The Power of the TikTok Generation: Female Athletes Raising the Standards Above Their Male Counterparts

LIna Nielsen recalls the moment when inspiration struck. While lounging around the Olympic Village in Paris with her sprinting comrades, she felt bored. “I turned to Yemi Mary John and said, ‘Let’s transform this into TikTok,'” Nielsen recounted. She retreated to her room, grabbed the flip phone assigned to each player, and entered the following into an Excel sheet: “Come on, come at me.”

Shortly after, she swiftly created a five-second parody of Kelly Rowland’s music video text message blunder. “It’s amusing how a video that’s both simple and effortless can be so impactful,” Nielsen remarked with a chuckle. She still finds it hard to believe that her TikTok channel was the most popular among all British athletes at the Olympics, surpassing even the second-place finisher Tom Daley. By the end of the two-week Olympic event, her channel had more views than the Australian and German teams combined.

Nielsen, along with her twin sister Raviai, who also participated in the Paris Games, joined countless athletes in sharing glimpses of village life, ranging from chocolate muffins to cardboard beds. “It served as a good distraction because too much focus on competition can lead to intensity. Social media helped to take my mind off things,” she stated. While Nielsen was defeated in the 400m hurdles semi-finals, she later aided the British relay team in clinching a bronze medal in the 4x400m event.

The “TikTok Olympics” of 2024 uncovered surprising trends, revealing that female athletes outnumbered their male counterparts on social media platforms. Research conducted by the Women in Sport Trust disclosed that female athletes constituted 69% of TeamGB’s total TikTok content and 67% of its views. Globally, women’s voices dominated the discourse in Paris, spanning from Australian water polo ace Tilly Kearns to Dutch skateboarder Keet Oldenbubing.

American gymnasts’ feeds showcased Mykayla Skinner criticizing her former teammate’s work ethic before seizing the gold medal, and Simone Biles celebrating post-victory with the caption, “Champions. Lack of talent, lazy, Olympians.” The subsequent attention on this post evolved into its narrative.

However, the standout star of the competition was American rugby luminary Ilona Maher. Her signature lipstick and unfiltered demeanor in the fake Love Island video from the Olympic Village captured hearts. The 28-year-old, who bagged a bronze medal for the United States in Paris and was a runner-up on Dancing with the Stars, soared to fame upon joining the Bristol Bears team recently.

“I won’t even earn six figures in rugby, that’s the harsh reality,” Maher shared in a recent interview. “Some might perceive that I’m not serious about my career, with TikTok-ing and all, but it’s necessary for me. That’s where I generate most of my income.”

Her candidness plays a vital role in her appeal. “She stays true to herself,” remarked rugby sevens player Ellie Boatman, who scored in the quarter-final clash between Great Britain and the United States. “Her authenticity resonates with audiences. She candidly shares about her journey. Initially hesitant, she now takes pride in it, something that many women can relate to.”

Boatman has amassed a substantial following of her own, with her kit rundown being Team GB’s most-viewed video. Her online presence has grown through open discussions about overcoming eating disorders, advocating social media as a platform for sportswomen to exhibit vulnerability and authenticity.

“Previously, athletes merely kept their focus on performing and diligent work,” Boatman reflected. “Now, people are more intrigued by the person behind the athlete. It’s wonderful to witness more narratives about personal journeys unfold recently.”

In an era where highly-paid male athletes appear disconnected from reality, empathy becomes a unique selling point in the sports industry.

Jenny Mitton, managing partner and head of women’s sport at M&C Saatchi Agency, noted that sportswomen naturally possess effective social communication skills due to the historical need for them to advocate for themselves. “When they are passionate about an issue, be it excelling in the sport or combating discrimination, their sincerity shines through, resonating with audiences,” Mitton added. She pointed out that authenticity is what flourishes on social media platforms.

This newfound power of female athletes in addressing important issues on social media is seen as a positive development by Lina Nielsen, who, living with multiple sclerosis, aspires to advocate for those with disabilities. “Using my voice to raise awareness about MS is something I strive for,” Nielsen expressed, highlighting the impact social media has in driving change and creating a platform for important conversations.

The bonding power of Cheerios leads to creation of innovative robot

A Cheerios-inspired robot that emits alcoholic fuel using fluorescent dye.

Jackson K. Wilt et al. 2024

The same phenomenon as beetles floating on a pond and Cheerios growing in clusters. You can combine them inside a cereal bowl to make a small floating robot.

One such effect, the Marangoni effect, occurs when a fluid with a low surface tension spreads rapidly across the surface of a fluid with a high surface tension. To take advantage of this effect, stenus There are beetles that have evolved to fly around ponds by secreting a substance called stenusin, and toy boats that run on soap.

To explore how engineers can use this, jackson wilt Harvard University and his colleagues 3D printed round plastic pucks about 1 centimeter in diameter. Each had an air chamber for buoyancy and a small fuel tank containing 10 to 50 percent alcohol, which has a lower surface tension than water. The alcohol gradually leaks out of the pack and the pack moves across the surface of the water.

The researchers used alcohol, which evaporates, as fuel, unlike soap, which ends up contaminating the water and ruining the Marangoni effect. It turns out that the stronger the alcohol, the better the results. “The beer would be pretty bad,” Wilt says. “Vodka is probably the best thing you can use. Absinthe…that's a lot of propulsion.” At top speed, the robot moves at 6 centimeters per second, and some experiments propelled the puck for as long as 500 seconds. It has been confirmed that

By printing pucks with multiple fuel outlets and gluing them together, researchers can also create larger devices that can make wide curves or rotate in place. Using multiple packs also allows researchers to study the “Cheerios effect,” where cereals and other similar floating objects cluster together. This occurs because they form a meniscus, or curved surface, in the fluid, and these surfaces are attracted to each other.

Wilt said 3D printed devices could be useful in education to help students intuitively understand concepts related to surface tension, but could also be carefully designed to produce more complex and elegant behavior. If this technology is developed, it can be expected to be applied to environmental and industrial processes.

For example, if there is a substance that needs to be dispersed throughout the environment and also acts as a suitable fuel, the robot can automatically disperse it around it. “Say you have a body of water that needs to release a chemical and you want it to be distributed more evenly, or say you have a chemical process that needs to deposit material over time,” Wilt says. . “I feel like there's some really interesting behavior here.”

Silk hydrogel battery could power pacemakers in mice

SEI 2269283401

A small soft lithium-ion battery made from water droplets

oxford university

The smallest soft lithium-ion battery ever made consists of just three tiny droplets formed from a silk-based hydrogel. Droplet batteries can provide pacemaker-style control and deliver defibrillator shocks to beating mouse hearts, but could eventually be used in biomedical implants and wearable electronics for humans. It may supply electricity.

“Potentially, our small battery could be used as an implantable microrobotic battery, which could be moved to a target location by a magnetic field and release its energy for treatment.” . Yuka Zhang at Oxford University.

Zhang and colleagues designed the small battery as three connected droplets that can self-assemble in solution after injecting various components into the liquid with a microsyringe. One droplet contains lithium manganese oxide particles and serves as the battery's negative electrode. The second droplet contains lithium titanate particles and serves as the positive electrode. A central droplet filled with lithium chloride separates these electrodes. UV light energizes the battery by breaking down the layers that separate each droplet, allowing lithium ions to flow freely between the droplets.

Droplet batteries are one-tenth the length of traditional soft lithium-ion batteries. At just 600 micrometers, it is about six times as wide as a human hair. The battery is also 1000 times smaller in volume than similar flexible lithium-ion batteries. The central droplet can also incorporate magnetic nickel particles, allowing the battery to be controlled remotely via an external magnetic field.

Such a small battery also provides an unprecedented amount of energy considering its small size. Wei Gao at the California Institute of Technology. “This energy density is significantly higher than what has been achieved with other similarly sized batteries,” he says.

The droplet battery was tested on a mouse heart removed from the animal's body. These successfully functioned as defibrillators to restore normal heartbeats and as pacemakers to regulate heartbeats. Additional testing showed that the battery retained 77% of its original capacity after 10 charge/discharge cycles.

The simplicity and scalability of such droplet batteries could be a potential advantage over traditional battery manufacturing in the future, Gao said. He suggested that such batteries could power minimally invasive biomedical implants and biodegradable medical devices.

“What impressed me most is how this soft battery mirrors the aqueous environment of human tissue by being hydrogel-based,” Gao says. “However, we still need to consider the safety and biocompatibility of the materials used in this battery, especially as we move towards commercialization and further research applications.”

Rebuilding democracy: unleashing the true power of the people

Many of us entered this so-called super-election year with a sense of foreboding. So far, not much has happened to allay these fears. Russia’s war against Ukraine has exacerbated the perception that democracy is under threat in Europe and beyond. In the United States, presidential candidate Donald Trump self-proclaimed dictatorial tendenciesfacing two assassination attempts. And more broadly, people seem to be losing faith in politics. A 2024 report from the International Institute for Democracy and Electoral Assistance states that “most citizens in diverse countries around the world have no confidence in the performance of their political institutions.”

By many objective measures, democracy is not functioning as it should. The systems we call democracies tend to favor the wealthy. Political violence is on the rise, legislative gridlock is severe, and elections are becoming less free and fair around the world. Nearly 30 years have passed since pundits proclaimed the triumph of Western liberal democracy, but their predictions seem further away than ever from coming true. what happened?

According to Rex Paulson At the Mohammed VI Institute of Technology in Rabat, Morocco, we have lost sight of what democracy is. “We have created a terrible confusion between the system known as a republic, which relies on elections, political parties, and a permanent ruling class, and the system known as democracy, where the people directly participate in decisions and change power. The good news, he says, is that the original dream of government by the people and for the people can be revived. That’s what he and other researchers are trying to do…

Evacuations and power outages as wildfires rage in California and Nevada

California wildfires spread rapidly on Tuesday as firefighters faced strong winds, dry conditions, and a heatwave that pushed temperatures into triple digits in the Los Angeles area. However, cooler temperatures are predicted, and the fires may soon be contained.

Firefighters were also contending with blazes in western Nevada, just south of Reno, in extremely windy conditions. The National Weather Service issued red flag warnings for most of Nevada and parts of Southern California. Vast tracts of land were at risk of ignition.

The fires have added pressure to what has already been a busy season for firefighters across the Western U.S., burning nearly 7 million acres, more than double last year’s total. Over 24,000 firefighters were mobilized as of Tuesday.

Rhine fire spreads in Southern California

The Line Fire, burning in the foothills of the San Bernardino National Forest, poses a threat to approximately 65,600 structures. The fire had expanded to 26,400 acres as of Tuesday morning and was only 5% contained, according to CalFire.

The fire, which started on Thursday night in East Los Angeles, triggered evacuation orders across the area with 9,200 buildings, primarily homes, at risk, said Fire Information Officer Arnold Menjivar.

Menjivar expressed concern about the fire’s proximity to homes in Running Springs, the gateway to Big Bear Lake and Bear Mountain ski resorts.

“We’re very close,” Menjivar said, noting that firefighters were employing an aggressive response strategy but were wary of gusty winds in the canyon. “This is very challenging terrain.”

The Rhine fire led to the formation of its own weather system on Saturday, creating a fire cloud resembling a thunderstorm. Fire clouds emerge when a fire generates its weather pattern. The cloud produced around 280 lightning strikes, which hit the ground. According to the National Weather Service.

Pyrocumulus has also been observed at two other sizable fires in Southern California: the Airport Fire in Orange County and the Bridge Fire in Angeles National Forest.

A red flag warning surrounding the Rhine Fire area is set to expire at 8 pm on Tuesday night, and the arrival of cooler temperatures starting Wednesday “may lead to reduced fire activity and increased fuel moisture,” as per Cal Fire.

Governor Gavin Newsom declared a state of emergency on Saturday due to the Rhine Fire, with fire officials announcing on Monday that the California National Guard would deploy four Black Hawk helicopters, other aircraft, and 80 soldiers to support the Modular Aerial Firefighting System. Approximately 2,100 firefighters were battling the blaze.

Evacuation Order and fire alerts were issued for several towns in the foothills east of California Highlands, outside San Bernardino, and along the route to Big Bear Lake. The Bear Valley Unified and Redlands Unified school districts canceled classes on Monday and Tuesday due to the fires.

More fires rage in Southern California

Hot, dry weather has fueled additional fires in the Southern California hills, prompting further evacuations.

The Airport Fire erupted on Monday afternoon. A 7-acre forest fire broke out in Trabuco Canyon, Orange County, south of Los Angeles. Within hours, the fire had spread to an estimated 5,400 acres, as reported by the Orange County Fire Department. By Tuesday morning, the fire had expanded to 9,000 acres, stated the fire department.

The fire was initially believed to have originated near an airfield used by RC aircraft enthusiasts. The website for the local flying club, Trabuco Flyers, mentioned that Remotely The controlled aircraft was in flight when the fire broke out..

As a result of this fire, Evacuation warnings were issued for Robinson Ranch and Trabuco Plateau, along with other nearby communities.

Meanwhile, the Bridge Fire ignited on Saturday in Angeles National Forest east of Los Angeles. By Tuesday morning, the fire had grown to over 3,800 acres and remained 0% contained. Residents from north of San Antonio Dam to Mount Baldy Resort, Other communities.

Dangerous conditions in the Sierra Nevada foothills

Windy, dry conditions have put firefighters on high alert near Reno, Nevada. The Davis Fire has charred nearly 5,600 acres and is currently 0% contained. As stated in a status update on Tuesday.

The fire Davis Creek Regional Parkbroke out just south of Reno on Saturday, burning substantial timber and brush, causing damage to at least 14 structures, road closures, and evacuations for approximately 12,000 to 14,000 people.

The fire also resulted in power outages, leaving 17,000 customers without electricity on Saturday. About 3,000 customers in Washoe County, Nevada, were still without power as of Tuesday morning. Power outage.Us.

Over 400 personnel are actively combating the blaze. El Dorado County Fire Department video Footage shared on social media depicted intense flames engulfing the densely wooded mountains and thick smoke clouding the sky.

Actor Jeremy Renner is among the community members affected by the Davis fire, and on Sunday, he shared an Instagram Story showing a massive plume of smoke billowing from the mountain. People Magazine Reportedly, he posted additional photos on Tuesday showcasing firefighters in action and a plane releasing pink fire retardant.

Tuesday marks the final day of high temperatures for the most at-risk areas burning in Nevada and Southern California.

A cold front from the Pacific Ocean is expected to lower temperatures by 10 to 15 degrees Fahrenheit in Southern California on Wednesday.

A cold front is also anticipated to move into the Reno area on Wednesday, which may not necessarily benefit the fires as it could bring stronger winds.

In areas prone to gusts, mountaintop winds could reach 50 mph. As per the National Weather Service forecast:.

The Guaranteed Method to Lose Weight and Maintain it: The Power of Fasting

In the past, intermittent fasting was not a choice due to scarcity of food. People would go hours or days without eating. Today, we have access to food whenever we want. This shift in eating habits has led to questions about the benefits of fasting and its potential reintroduction.

Intermittent fasting usually involves limiting food intake to specific times or days, like eating only for eight hours out of 24 (16:8 diet) or restricting calories for two days out of seven (5:2 diet).


Strong Points

Intermittent fasting can help with weight loss, particularly fat loss, as it reduces overall caloric intake. It also provides structure to eating days and can be flexible and intuitive. Some benefits include decreased hunger, lower levels of the hunger hormone ghrelin, reduced appetite, and improved fat burning.

Fasting may also lower the risk of type 2 diabetes and improve vascular health. Research shows that intermittent fasting is beneficial for cardiometabolic health and may have positive effects on long-term cardiovascular health.

There is evidence to suggest that fasting can protect against issues related to aging, improve autophagy, and potentially benefit brain health and cancer risk, but more research is needed to support these claims.

Cons

Concerns about fasting include potential muscle loss and the lack of long-term studies to support its safety. Some studies suggest that restricting eating to less than eight hours a day could increase the risk of death from cardiovascular disease, but data collection methods and sample sizes in these studies may be flawed.

There is also a risk of reduced protein intake with intermittent fasting, which could be problematic for some individuals, especially those with a history of eating disorders or health conditions that require regular meals.

Experts recommend ensuring adequate protein intake and incorporating strength training if trying intermittent fasting. It’s important to approach fasting like any other diet, not as a permanent solution, and to pay attention to food choices when breaking the fast.

About our experts

Dr. Jason Fung, Dr. Darryl Gioffre, Brady Holmer, and Drew Price are experts in their fields and have published work related to intermittent fasting, nutrition, and health.

New Google AI technology significantly decreases computing power required for weather forecasting

AI could help us predict the weather more accurately

LaniMiro Lotufo Neto/Alamy

Google researchers have developed an artificial intelligence that they say can predict weather and climate patterns as accurately as current physical models, but with less computing power.

Existing forecasts are based on mathematical models run by extremely powerful supercomputers that deterministically predict what will happen in the future. Since they were first used in the 1950s, these models have become increasingly detailed and require more and more computer power.

Several projects aim to replace these computationally intensive tasks with much less demanding AI, including a DeepMind tool that forecasts localized rainfall over short periods of time. But like most AI models, the problem is that they are “black boxes” whose inner workings are mysterious and whose methods can’t be explained or replicated. And meteorologists say that if these models are trained on historical data, they will have a hard time predicting unprecedented events now being caused by climate change.

now, Dmitry Kochkov The researchers, from Google Research in California, and his colleagues created a model called NeuralGCM that balances the two approaches.

Typical climate models divide the Earth's surface into a grid of cells up to 100 kilometers in size. Due to limitations in computing power, simulating at high resolution is impractical. Phenomena such as clouds, turbulence, and convection within these cells are only approximated by computer codes that are continually adjusted to more closely match observed data. This approach, called parameterization, aims to at least partially capture small-scale phenomena that are not captured by broader physical models.

NeuralGCM has been trained to take over this small-scale approximation, making it less computationally intensive and more accurate. In the paper, the researchers say their model can process 70,000 days of simulations in 24 hours using a single chip called a Tensor Processing Unit (TPU). By comparison, competing models, called X-Shield A supercomputer with thousands of processing units is used to process the simulation, which lasts just 19 days.

The paper also claims that NeuralGCM performs predictions at a rate comparable to or better than best-in-class models. Google did not respond to a request for an interview. New Scientist.

Tim Palmer The Oxford researcher says the work is an interesting attempt to find a third way between pure physics and opaque AI approximations: “I'm uncomfortable with the idea of ​​completely abandoning the equations of motion and moving to AI systems that even experts say they don't fully understand,” he says.

This hybrid approach is likely to spur further discussion and research in the modeling community, but time will tell whether it will be adopted by modeling engineers around the world, he says. “It's a good step in the right direction and the type of research we should be doing. It's great to see different alternatives being explored.”

Unlocking the Power of Aura: Aristotle’s Influence on the New Currency of Cool | Life & Style

yes
You can track your calories, steps, and even the number of streams on your favorite songs. Now, you can also quantify your awesomeness with Aura Points, which determine your level of attractiveness. (It’s basically charisma, and if you didn’t know that, you just lost 100 Aura points.)

Asking someone out and getting a “yes” results in losing 100 aura points. Using Snapchat after the age of 19 is frowned upon and leads to a deduction of 1,000 aura points. Answering a question confidently in class, even if it’s wrong, puts you in the negative.

According to a TikTok explanation, this trend has caused a 378% spike in posts with the hashtag #aurapoints between May and June. It’s all about exuding a positive, carefree, and confident attitude to earn points and gain entry into the cool-kids club.

The concept of Aura Points is a modern twist on the elusive “it” factor, popularized by stars like Clara Bow and Evelyn Nesbitt, now reimagined for the younger generation. Gain your Aura Points to join the cool club, or risk losing them and facing consequences.

Stories on TikTok illustrate how people earn and lose points. Acting breezy and confident in tough situations earns you points, while staying with a cheating partner results in a deduction that no aura person would accept. Some scenarios are absurd but entertaining.

While Aura Points are mostly light-hearted, some creators use them to symbolize personal growth moments. It can be a way to reflect on important life choices and behaviors that define one’s character positively.

Young TikTok users share anecdotes of their point-earning and losing experiences. The trend aligns with Gen Z’s interest in cosmic belief systems like astrology. It offers a playful yet insightful approach to evaluating personal growth and character development.

Aura Points may seem like a modern TikTok fad, but they draw parallels to ancient virtue ethics from Greek and Roman philosophy. It’s more than just a superficial trend; it encourages self-reflection and moral alignment with personal values.

The concept of Aura Points also relates to moral credit, where positive actions counterbalance potential negative ones. It serves as a gamified system to assess behavior and invite constructive criticism.

Just like Alain de Botton’s notion of “status anxiety,” Aura Points reflect the ongoing concern for how others perceive us and our quest for self-worth. It’s a way for individuals to navigate social evaluation and engage in status transactions.

Understanding the philosophy behind this TikTok trend? Congratulations, you’ve earned 1,000 Aura points!

Some skeptics warn that EVs will strain the power grid, but they could actually help to solve the problem

picture
Electric cars scares some people of the dark: their batteries produce much less carbon dioxide but require more power to run, prompting ominous warnings that Britain and other wealthy countries could plunge their citizens into darkness if they ban new petrol and diesel sales.

In recent months, UK net-zero skeptic newspapers have warned that a shift to EVs “risks overwhelming the grid and causing catastrophic blackouts” if intermittent solar and wind don't provide the needed power. Another article argued that “we don't need an enemy force to plunge us all into darkness – just some electricity customers doing their normal thing on a normal winter's night.”

But many who work in the electric vehicle industry believe these fears may be unfounded, arguing that the transition to electric vehicles is an exciting, potentially lucrative opportunity to build a smarter, greener energy system.


In the UK, polluting coal-fired power plants have been largely replaced by wind farms and solar panels. These renewable energies do not emit carbon dioxide, but they suffer from intermittency problems and cannot provide enough power on cloudy days or at night when there is no wind. Add in the prospect that all new cars will be electric by 2035 and it is not an exaggerated question how the power grid will keep supply and demand in balance.

Shifting demand

The transition to electric vehicles will undoubtedly require more electricity generation as electric vehicles, rather than land-based fossil fuels, become the primary source of energy for transportation, but smart technology can be used to shift demand away from peak times, such as 5pm in winter, when demand for electricity risks outstripping supply.

This isn't just a pipe dream: home charger company MyEnergy calculates that if balancing services were enabled across all installed compatible chargers, it could “provide over 1GW of demand-shifting flexibility to the grid, more than 98% of the UK's major fossil fuel power stations.”

Octopus Energy, which has quickly grown to become the UK's largest electricity supplier, says its Go electricity tariff manages the charging of the batteries of 150,000 electric vehicles. Charging them all at once would require 1GW of power, but smart chargers hold off charging until off-peak hours at night, shifting demand away from peaks. Electricity is also cheaper during off-peak hours, with clear benefits for consumers: Octopus says its customers save an average of about £600 a year.

One gigawatt is the equivalent of a medium-sized power station, enough to power 600,000 homes. Electric vehicles on UK roads are already on the rise in the UK. Peak electricity demand in winter is 61.1GWAccording to the National Grid, delaying charging for just a few hours can help reduce energy consumption.

Jack Fielder, chief strategy officer at MyEnergy, said: “If every EV charger could provide a grid balancing service and every driver took part in a grid balancing program, we could collectively eliminate periods of strain on the grid.”

It could also be useful when power supply exceeds demand, such as on warm, windy nights, said Chris Pateman-Jones, chief executive of charging company Connected Curve.

“Instead of wasting renewable energy, I see EVs as a giant sponge,” he says. For consumers, there will be little change: Connected Curve data shows that most cars are already charged by midnight, leaving them idle for hours before they're needed.

Powered by car battery

It's not just the timing of when electrons flow into car batteries that will help the National Grid Electricity Supply Operator (NGESO), the company responsible for balancing the U.K. power grid: It calls demand shifting a “low-regret action that will help reduce the impact on peak demand and reduce renewable curtailment,” but it also wants electrons to flow in the other direction.

Vehicle-to-grid technology is an attractive prospect: instead of building power plants, hydroelectric storage, or stationary battery fleets, the idea is to harness the energy stored in car batteries. Cars could become portable power packs, providing backup for homes in the event of a blackout, and even allowing drivers to earn money by selling power back to the grid.

NGESO is Annual estimate It predicts what the UK electricity system will look like in 2035 and 2050. It sees a growing role for cars feeding power back into the grid, and in the most optimistic scenario, capacity could reach 39GW (equivalent to one-tenth of the vastly expanded generating capacity).

Research indicates that the Aurora Borealis may soon jeopardize our power infrastructure

Seeing the Northern Lights is a dream for many, and the recent intense geomagnetic storm in May provided that opportunity for some. However, scientists are becoming increasingly concerned about the threat these natural light displays pose to modern infrastructure.

New research has revealed a connection between the Northern Lights and strong electrical currents known as geomagnetically induced currents (GICs), which can cause damage to critical infrastructure like pipelines and undersea cables.


Researchers have found that the angle at which an interplanetary shock wave hits Earth’s magnetic field plays a crucial role in determining the strength of these currents.

“Auroras and GICs are linked through the same space weather phenomenon,” explained Dr. Denny Oliveira, a researcher at NASA’s Goddard Space Flight Center. He emphasized that the aurora is a visual indication of the potential generation of GICs on the ground.

When solar particles interact with Earth’s magnetic field, geomagnetic storms are created, leading to the formation of the aurora. Interplanetary shock waves, arising from the Sun’s solar wind, also contribute to this process.

Interplanetary shock waves are formed similar to the sonic boom of a jet plane breaking the sound barrier. These shock waves compress Earth’s magnetic field and can generate powerful electrical currents that pose a threat to infrastructure conducting electricity.

Mitigating measures are crucial to protecting vulnerable infrastructure from the impact of interplanetary shock waves, as demonstrated by the severe power outage in Canada in 1989 following a geomagnetic storm. Oliveira emphasized the importance of monitoring and managing electrical circuits to prevent equipment damage.

Further research is needed to safeguard critical infrastructure from the strongest shock waves Earth encounters, Oliveira concluded.

California is facing an unexpected energy challenge due to excessive solar power use

Solar panels have become a common sight in suburban neighborhoods in California. However, the state’s ambitious clean energy vision has led to a unique challenge – sometimes producing more solar energy than it can use effectively, resulting in wastage of clean energy.

This excess of solar energy has resulted in a phenomenon known as the “duck curve,” where solar generation surpasses demand. This issue is most pronounced on sunny spring days when demand for electricity is low.

The surplus energy is often exported to other parts of the Western U.S. due to California’s grid connectivity, but in some cases, it may need to be curtailed. Independent System Operator data shows that California has lost a significant amount of renewable energy this year, primarily solar power.

To address this challenge, proposals have been made to increase electricity supply through additional transmission lines and more battery installations to store excess power. However, recent changes in financial incentives for homeowners installing solar power have negatively impacted the rooftop solar industry in California.

Despite the setbacks, Governor Gavin Newsom remains optimistic about California’s clean energy progress, pointing out the state’s significant solar power generation and increasing battery installations. Critics of the incentive changes argue that it could lead to higher energy costs for non-solar customers and hinder the state’s transition to renewable energy.

As California navigates these challenges on its path to achieving 100% clean energy by 2045, the state’s decisions are closely watched by other states considering similar transitions. The rooftop solar industry plays a crucial role in this transition, as highlighted by industry experts.

Google fails to meet major climate goal due to high AI power consumption

Three years ago, Google launched an ambitious plan to address climate change, aiming to achieve “net zero” emissions by 2030. This goal entails not emitting more climate-affecting gases into the atmosphere than it removes.

However, a recent report released by Google indicated that it is far from reaching this objective. Emissions are projected to increase by 13% in 2023 compared to the previous year and have surged by 48% since the base year of 2019.

The company attributes last year’s emission growth to electricity-intensive agriculture. The burning of coal or natural gas for electricity production releases greenhouse gases like carbon dioxide and methane, contributing to global warming and more extreme weather events.

Despite being a leader in climate change initiatives, Google faces challenges in meeting its net-zero target. Experts suggest that the rapid expansion of data centers, which require significant energy and resources, could hinder the transition to clean electricity and exacerbate climate change.

To address these issues, Google’s chief sustainability officer, Kate Brandt, emphasized the need for continued evolution and innovation in the company’s approach. She acknowledged the uncertainties surrounding the environmental impact of AI and the importance of partnering with cleaner companies and investing in sustainable practices.

Ultimately, achieving a net-zero goal by 2030 will require concerted efforts and collaboration across industries to accelerate the transition to clean energy sources and mitigate the effects of climate change.

Google’s commitment to using renewable energy and implementing energy-efficient practices in its data centers and offices is a step in the right direction. However, there is a need for ongoing improvement and collaboration to address the challenges posed by climate change.

Playing Out Each UK Party’s First Years of Power in a Video Game Revealed Disastrous Results

circleWhether referred to as manifestos or contracts, the documents released by political parties before elections often lack substance despite their length. Filled with idealistic scenarios, vague proposals, and questionable cost estimates, it’s difficult to gauge the true impact each party’s implementation would have on the UK. To investigate this, I’ve been inputting party documents into the political strategy video game Democracy 4 to see the outcomes. The results are… well, you can see for yourself.

Democracy 4 allows players to simulate their political fantasies or nightmares and witness how their decisions influence their chances of re-election. Developed by Positech Games, the game models various democracies, including the UK, with their respective institutions, government policies, and tax rates based on publicly available data. The simulation features thousands of virtual voters, each with unique characteristics. For example, the majority of UK citizens identify as capitalists, but they may also be middle-income, affluent, or farmers, commuters, or self-employed.

Democracy 4 serves as an approximate representation of the British political landscape of 2024, offering insights into the potential outcomes of each major party’s agenda. By testing the policies of the Conservatives, Labour, and the Liberal Democrats, the game reveals who stands to benefit, who may be adversely affected, and whether any real progress can be achieved.

Keep in mind that Democracy 4 does not simulate Scotland and Wales separately, thus unable to capture the nuances of the SNP and Plaid Cymru’s plans. I have focused on the Conservatives, Labour, and the Liberal Democrats in my simulations. Each party assumes power with a slim 10% majority on July 5th, facing similar economic challenges. Can Labour bridge the funding gap across all sectors by boosting the UK economy? Will the Conservatives’ tax cuts stimulate business growth? And can the Liberal Democrats’ wealth tax and public service investments eliminate the national debt deficit?

The Power of Music to Discover the Universe’s Hidden Secrets

Music and physics are two disciplines that transcend mere study to become intertwined aspects of human creativity. This hidden harmony between music and physics has been acknowledged by luminaries such as Albert Einstein, who expressed a longing for music had he not pursued physics.

As someone who navigates both fields, I have uncovered deeper connections between them. My journey began in the Bronx, where the worlds of hip hop and science collided in unexpected ways. Later, while studying at Imperial College London, I witnessed the fusion of artistic expression and scientific inquiry in Brian Eno’s studio.

This intersection between art and science inspired me to explore further and led me to write the book “Physics Jazz.” Through this exploration, I delved into the commonalities between music and physics, from improvisation to quantum uncertainty.

My passion for sharing these discoveries prompted the creation of the course “Jazz in Modern Physics” at Brown University, bridging the gap between disciplines and offering students a new way to appreciate the symphony of the universe through mathematics and melody.

Believing in the transformative power of education, I founded the “Sound + Science” after-school program to provide underserved students with an opportunity to explore the fusion of music and physics through hands-on experimentation and collaboration.

This fusion of art and science celebrates human ingenuity and the interconnectedness of the universe. In embracing this harmonious blend, we can unlock the mysteries of the universe and delve into the depths of the human soul.

The EPA’s latest regulation requires coal-fired power plants to either capture emissions or cease operations

WASHINGTON – The Environmental Protection Agency issued a rule on Thursday that will require coal-fired power plants to capture smokestack emissions or shut down. This new regulation aims to limit greenhouse gas emissions from fossil fuel-fired power plants, which are a major contributor to global warming. It is part of President Joe Biden’s pledge to eliminate carbon pollution from the power sector by 2035 and the entire economy by 2050.

The rule includes measures to reduce toxic wastewater pollutants from coal-fired power plants and safely manage coal ash in unlined retention ponds. EPA Administrator Michael Regan stated that the rule will reduce pollution, protect communities, and improve public health while ensuring a reliable electricity supply for the nation.

Industry groups and Republican-leaning states are expected to challenge the rule, citing concerns about the reliability of the power grid. However, environmental groups have praised the EPA’s actions as crucial in combating climate change and protecting public health.

The rule sets standards for existing coal-fired power plants to control carbon emissions, with future plants required to capture up to 90% of their carbon pollution. Coal-fired power plants must reduce or capture 90% of their carbon emissions by 2032 to continue operating beyond 2039. Plants scheduled to be retired by 2039 will also face stricter standards.

The EPA rule does not mandate carbon capture and storage technology but sets a cap on carbon pollution that power plant operators must adhere to. The regulation also addresses toxic wastewater pollution from coal-fired power plants and the safe management of coal ash, a hazardous byproduct of coal combustion.

Overall, the EPA’s new rule represents a significant step in reducing carbon pollution, protecting public health, and moving towards a cleaner energy future for the United States.

Muting people on social media can be done quickly, for free, and has the power to profoundly impact your life

I I don’t usually believe in life hacks. I’d like to imagine that with one simple adjustment my life would reappear like a cracked tennis court, but as time and experience have shown, positive change usually happens slowly and gradually.

But there is one hack that I truly believe in. It’s fast, free, and will instantly change your life for the better. Just mute the annoying people on social media.

The process varies by platform. Typically, you would go to the offending poster’s profile page or one of her posts and tap “Mute,” “Snooze,” or “Unfollow.” But that’s it. Thanks to this digital dust, social media is cleaner, or at least less dirty than it used to be. They’ll disappear from your timeline, and so will the various little annoyances they caused. Also, unlike unfollowing or blocking someone, the muted party won’t know they’ve been silenced, so there’s no risk of awkwardness or drama. .

Several people are muted. Some of them are people you don’t want to unfollow. I unfollowed some people, but I muted them because others might repost and pollute my pure timeline. One is a semi-celebrity who was rude to me about work many years ago. Another person was rude to my friend. There are also ex-lovers and people who are always humble and boastful and make you want to bang your head against something hard.

These people brought out the worst in me. When I saw their posts, I felt angry, mean, and small. I wondered how much it would cost to buy billboards along major highways with bullet points detailing just how bad it really is.

Luckily, I rarely think about these people anymore because I’ve muted them on all platforms. I usually forget these people exist unless someone brings it up in conversation. They were weeded from the lush garden of my brain.

But don’t just take my word for it.

Three lines of bold text that say “Actually,” then “Read more about how to live a good life in a complex world,” then pinkish text that says “Continue here.” ‘Graphic section with lavender pill-shaped buttons’

Bailey Parnell, founder and president of the Center for Digital Wellbeing, said, “Muting accounts that repeatedly make you uncomfortable is setting up digital boundaries to create a healthier digital environment.” I am. This allows you to avoid offensive content without disconnecting. It’s a solution, she says, to the complicated situation where a relationship with someone is important to you despite their annoying online presence.

“This allows you to maintain your social and professional networks while also maintaining your mental health,” she says.

This may seem like obvious advice. Still, it can be difficult to follow. The frustration you feel when you see someone’s bad posts can be accompanied by a sense of satisfaction. It’s like, “Look!” It’s annoying!

“There can be a dopamine rush at the end of a big emotion,” says Monica Amorosi, a certified trauma therapist in New York City. We may begin to crave the adrenaline spike that comes with content that makes us feel shocked, angry, or disgusted.

Skip past newsletter promotions

“If we lead a mundane life, lack stimulation, are bored or overwhelmed, consuming this substance can be a form of entertainment or distraction,” says Amoros. says Mr.

Amorosi emphasizes the importance of not creating a “space of ignorance” in your feed by avoiding different perspectives on current events and alarming news. But this does not mean that social media should only be used to access upsetting information. Our feed can be used for “healthy, positive education, connecting with like-minded people, understanding the nuances and diversity of the world, fact-checking information, and learning new hobbies and ideas,” she says. say.

So muting is probably most effectively applied against people who annoy you in a bland, everyday way, such as an arrogant colleague. Not seeing humble braggarts pretending to be ashamed of their professional successes does not limit my worldview. Instead, I get back the 5-10 minutes I might have wasted taking screenshots of posts and complaining to friends about them.

Frankly, I haven’t done anything with the time I’ve gained by not badmouthing the people I’ve muted. But how nice that at least he has days when he’s comfortable for even five minutes.

So feel free to mute yourself and often. And what if you disagree with me? Please mute. You never know!

Strong winds have the power to generate massive waves, scientists reveal

A rogue wave is a single swell that is much higher than nearby waves and can cause damage to ships and coastal infrastructure. Ocean waves are one of the most powerful natural forces on Earth, and they could become even more powerful as global trends suggest ocean winds will blow even stronger with climate change. there is. Scientists at the University of Melbourne have discovered in a new study that rogue waves are generated by strong winds and unpredictable wave patterns, confirming an idea previously only proven in the lab.



Toffoli other.We report direct observations of surface waves from a stereo camera system and simultaneous measurements of wind speed during an expedition across the Southern Ocean during the Antarctic winter aboard a South African icebreaker. SA Agulhas II. Image credit: Alessandro Toffoli.

“Rogue waves are huge, twice as tall as nearby waves, and appear out of nowhere,” said University of Melbourne’s Professor Alessandro Toffoli, lead author of the study.

Using cutting-edge technology and embarking on an expedition to one of the most unstable ocean regions on Earth, Professor Toffoli and colleagues have introduced a new technique for 3D imaging of ocean waves.

Operating a stereo camera on a South African icebreaker SA Agulhas II During their 2017 Antarctic expedition, they captured valuable insights into the behavior of waves in this remote region.

Their method, which mimics human vision through continuous imaging, allowed researchers to reconstruct the wavy ocean surface in three dimensions, providing unprecedented clarity into ocean wave dynamics. Ta.

The first scientific measurement of a rogue wave was the 25.6 m Draupner wave recorded in the North Sea in 1995. Since the beginning of the 21st century, 16 cases of suspected rogue waves have been reported to him.

“Scientists have long theorized that Antarctica’s rough seas and fierce winds can cause large waves to ‘self-amplify’, resulting in rogue wave frequencies. “However, this has not yet been tested underwater,” Professor Toffoli said.

The team’s observations, using numerical and laboratory studies that suggested the role of wind in the formation of rogue waves, provided validation of these theories in a real marine environment.

“Our observations show that unique sea conditions with rough waves occur during the ‘young’ stage of the waves, when they are most susceptible to wind effects. This suggests that wind parameters are the missing link,” Professor Toffoli said.

“Wind creates a chaotic situation where waves of different dimensions and directions coexist.”

“The wind causes young waves to grow higher, longer and faster.”

“During this self-amplification, waves grow disproportionately at the expense of neighboring waves.”

“We show that young waves are showing signs of self-amplification and are likely to be wind-driven.”

“Once every six hours, we recorded waves that were twice as high as nearby waves.”

“This reflects laboratory models. The theory is that sea conditions are more likely to self-amplify, creating more rogue waves.”

“In contrast, no rough waves were detected in mature oceans that are not influenced by winds.”

The authors highlight the critical importance of integrating wind dynamics into predictive models for rough sea prediction.

“This shows that scientists need to take wind into account thoroughly when developing tools to predict rogue waves,” Professor Toffoli said.

Nvidia Releases GB200 Grace Blackwell Superchip, Setting a New Standard for AI Power

Nvidia GB200 Grace Blackwell Super Chip

Nvidia

Nvidia has announced the most powerful “superchip” it has ever produced for training artificial intelligence models. The U.S. computing company, whose value has recently soared to become the world's third-largest company, has not yet disclosed the price of its new chips, but observers say they will be available to a small number of organizations.

The chip was announced by NVIDIA CEO Jensen Huang at a press conference on March 18 in San Jose, California. He showed off the company's new Blackwell B200 graphics processing unit (GPU). Each GPU is equipped with his 208 billion transistors, the tiny switches at the heart of modern computing devices, compared to his 80 billion transistors in Nvidia's current generation Hopper chips. He also revealed the GB200 Grace Blackwell Superchip, which combines two B200 chips.

“Blackwell will be a great system for generative AI,” Huang said. “And in the future, data centers will be thought of as AI factories.”

GPUs have become coveted hardware for any organization looking to train large-scale AI models. During his AI chip shortage in 2023, Elon Musk said his GPUs were “a lot harder to get than drugs,” and some academic researchers without access lamented that “GPUs are poor.” I did.

Nvidia says its Blackwell chips deliver 30x performance improvements compared to Hopper GPUs when running generative AI services based on large language models such as GPT-4, while consuming 25x less power. It claims to be 1 in 1.

OpenAI's GPT-4 large-scale language model required approximately 8,000 Hopper GPUs and 15 megawatts of power to run 90 days of training, whereas the same AI training could be performed using just 2,000 Blackwell GPUs. The company says it can run on 4 megawatts of electricity.

The company has not yet revealed the cost of its Blackwell GPUs, but given that Hopper GPUs already cost between $20,000 and $40,000 each, their prices could reach eye-watering levels. expensive. The focus on developing more powerful and expensive chips means they will be “available only to a select few organizations and countries,” he said. sasha ruccioni At Hugging Face, a company that develops tools to share AI code and datasets. “Aside from the environmental impact of this already highly ene… Read more

Power demand from data center expansion, driven primarily by the generative AI boom, is expected to double by 2026 and rival Japan's current energy consumption. If data centers that support AI training continue to rely on fossil fuel power plants, they may also be accompanied by a sharp increase in carbon emissions.

Global demand for GPUs also means more geopolitical complications for Nvidia, as tensions and strategic competition between the US and China increase. The U.S. government has instituted export controls on advanced chip technology to slow China's AI development efforts, saying it is critical to U.S. national security, so Nvidia is seeking performance improvements for Chinese customers. They are forced to produce lower versions of chips.

Epic Games challenges Apple and Google in Australia amid claims of market power abuse

When Apple’s first iPhone was released in 2007, all of its apps were created by Apple.

According to his biography by Walter Isaacson, Steve Jobs was reluctant to allow apps from third-party developers on the iPhone. He eventually succumbed to pressure with the launch of his App Store in 2008. However, the company wanted to maintain strict control over what was allowed on the platform: email. 2021 release schedule revealed.

The case, which will be heard over the next five months in Melbourne’s Federal Court, will center on Apple’s control over its empire. At the same time, Google, which has prided itself on having a more open ecosystem than Apple, will have its practices tested.


Two cases in Australia’s Federal Court were adjourned in April 2021, pending the outcome of a similar case in the United States. Epic Games, the maker of the popular game Fortnite, has spent the past three years in a global legal battle against Apple and Google, alleging abuse of market power over their app stores.


Fortnite announced a deal with Google in 2020 after Epic Games offered its own in-app payment system that bypasses the one used by the platform and reduced the fees Apple and Google receive on in-app payments. Removed from Apple’s app store.

Epic lost a 2021 antitrust lawsuit against Apple, but won a lawsuit against Google late last year. Although the Australian cases were initially separate, they are now integrated into one monolith. Judge Jonathan Beech decided to hear the two cases and a related class action at the same time to avoid duplication of witness evidence.

David and Goliath?

In an Australian lawsuit that originally began in 2020, Epic Games argued that Apple’s control over in-app purchases and Apple’s actions in banning the Fortnite app were an abuse of market power, and that it significantly reduced competition in app development. He claimed to have lowered it. The company also claims that Google has harmed Australian app developers and consumers by preventing them from distributing apps and choosing in-app payments on Android devices.

As with mobile phone operating systems, the litigation between Apple and Google has many similarities, but there are also important differences. Apple’s iOS and App Store are completely closed and controlled by Apple. This means that if you have an app on your phone and a payment is made through that app, it has to go through Apple.

Similar rules apply to the Play Store in Google’s Android operating system, but Google also allows apps to be “sideloaded,” or installed directly onto a phone without using the app store. It also allows phone manufacturers like Samsung to have their own app stores. Fortnite is still available on Android, but only through sideloading or the Samsung Store.

Companies charge fees for transactions in their app stores. In Google Play, he charges a commission of 15% for the first million dollars a developer earns each year, and above that he increases to 30%. If an Apple developer’s revenue in the previous year was less than $1 million, he would pay a 15% fee, but if it was more than that, he would pay a 30% fee.

Fees are common in the industry, with Epic’s own store charging developers a 12% fee.

Epic argues that it should be able to offer its store as a competitor to Apple’s store, and that it should also be able to offer alternative payment options within its official game store apps.


Google claims to be more open than the Apple App Store, but it was this openness that hurt the tech company in the US lawsuit. The jury found that tying the Google Play Store to in-app payments was illegal and that the company had entered into anti-competitive agreements with some developers to keep their apps on the Play Store.

In the Apple case, the judge took a narrower view, considering mobile game transactions specifically rather than app stores as a whole. The judge found that Apple is not a monopoly and is in competition with Google and other companies. The judge also upheld Apple’s concerns about the security implications of opening the App Store and sided with the company’s pursuit of intellectual property royalties through in-app payments.

Apple is expected to file a similar lawsuit in Australia. The company believes there is little difference between the cases and that the principles underlying Australian competition law are similar to US antitrust principles.

Apple sees Epic not as David the Goliath, but as a multibillion-dollar company seeking more profits at the expense of iPhone users’ safety.

Google claims that it not only offers customers a choice in the app store, but also offers alternative options for developers to sell their content outside of Google Play. It also points to permissions that allow sideloading of apps while maintaining user security, which Epic claims it is trying to water down.

“It’s clear that Android and Google Play offer more choice and openness than other major mobile platforms, and are a good model for Australian developers and consumers,” Google’s Government Affairs statement said. Vice President for Public Policy Wilson White said in a post this week. .


“We continue to have a right to sustainable business models that keep our users safe, grow our businesses in partnership with developers, and keep the Android ecosystem thriving and all Australians healthy. We will vigorously defend it.”

Apple forced to make changes to EU App Store

Initial submissions will last two weeks, followed by three months of evidence from fact witnesses and experts, followed by two weeks of final submissions, ending in mid-July.

Witnesses expected to testify include Epic CEO Tim Sweeney, who is in Melbourne for the hearing, as well as key executives from Apple and Google.

A concurrent class action lawsuit on behalf of Australian developers and consumers will fail if Epic’s lawsuit fails.

The case is unlikely to be resolved by the end of the year, and Beach is not expected to issue a verdict within six months, after which it could be appealed.

Whether or not Epic wins the battle, Apple and Google may ultimately lose the app store war. Apple has been forced to implement changes to its App Store in the European Union, including allowing alternative payment options and marketplaces, under the Digital Markets Act. As a result, Apple last week reinstated Epic’s developer account in the EU.

Epic says Apple’s implementation of these changes is incomplete, but other governments, including Australia, may follow suit.

Protecting the entire power grid from outages by rainproofing 1% of power lines

Damage from storms like Hurricane Harvey caused severe power outages to the Texas power grid.

Mark Ralston/AFP via Getty Images

Simulations suggest that storm sheltering just 1% of the power lines in a power grid can reduce the likelihood of a hurricane-induced power outage by a factor of five to one in 20. The demonstration, conducted on a mock version of the Texas power grid, could help improve the resiliency of power transmission systems around the world.

“The importance of different power lines to the overall system becomes clear only when studying the partial disruption of the power grid as the storm progresses,” he says. frank hellman at the Potsdam Institute for Climate Impact Research, Germany.

To identify the critical power lines most in need of protection, Hellman and his colleagues investigated how the power grid responds to widespread damage over time. They focused on the large-scale “failure cascade” that occurs after the initial storm damage. When power plants and transmission lines shut down to protect against further damage, secondary power outages can occur and increase the impact of a hurricane.

Researchers have determined that wind-related storm damage, such as damaged pylons and fallen tree limbs from gusts, and resulting damage to Texas during seven historic hurricanes between 2003 and 2020. simulated both a series of power outages that occurred on the power grid.

Rather than trying to predict individual power line failures, which can be caused by fallen trees or lightning strikes, researchers set each power line's probability of failure based on local wind speeds during each storm event. assigned. Their model maintains the same 20 critical transmission lines, where initial storm damage can cause a series of secondary line failures, even if they randomly vary the probability of failure for each line and rerun the simulation. Consistently identified electrical wires.

This experiment synthetic network model of the Texas Grid, which was previously developed by a team at Texas A&M University. It is not an exact replica of the actual physical grid, but represents the overall behavior of the grid. “None of the power lines in that grid are real power lines,” he says. adam burchfield at Texas A&M University. “Therefore, to see if these results hold true for the real Texas grid, we need to perform the study on at least a model of the real Texas grid.”

Power grid operators themselves can run this simulation with their own detailed power grid models, although independent researchers typically do not have access to such models for security reasons. Once you identify which specific lines are weak points, you can weatherize critical components of your grid.

Beyond Texas, such simulations can also model grids in other locations where similar storms have occurred. It says it “may provide an opportunity to validate the model and results.” Chuan Yi Ji from Georgia Tech in Atlanta was not involved in the study.

Hellman acknowledges that wind damage models have limitations. It does not take into account the possibility of further damage from flooding or how precautions grid operators can take to prevent power outages.

Still, Burchfield said the study's use of “different scenarios” to check the probability of outages in a realistic grid model further emphasized the study's main findings. “I think grid strengthening is a key element in making the grid more resilient,” he says. “And this paper shows that strategically choosing which transmission lines to strengthen is important to have the greatest impact on resiliency.”

The Power of Positive Male Role Models in Transforming the Social Media “Manosphere” | Social Media

I
Influencers like Andrew Tate have become synonymous with “toxic masculinity,” using a combination of motivational scoldings, fast cars, and demonstrations of sexual prowess to appeal to large audiences of young men and boys. It’s attracting.

But what about the other side of the coin? Are people creating content with healthier messages for the same audience? Or maybe men and boys simply don’t want to hear it? Or?

Jago Sherman, head of strategy at Goat Agency, an influencer subsidiary of marketing giant WPP, says: -Love, self-expression, fighting knife crime, education, but they don’t always make the headlines.



“People like Andrew Tate are using social media to make far-reaching and far-reaching unsubstantiated claims, as if they are providing a ‘quick-fix’ answer to a very complex problem. The problem, of course, is that these statements are most often not true, or are opinions disguised as facts.

In a social environment where creators compete for attention, this ‘shock factor’ content that can be consumed and understood very quickly can sometimes perform better than longer, thought-provoking, neutral content.

Against this backdrop, Labor last week announced plans to promote a more positive vision of masculinity. According to the proposal, schools would develop leaders from their own students who would help counter the misogynistic vision promoted by Tate and others, as well as be more critical of what they see on screen. Students will be supported to explain their analysis skills in class.

Some men who give a more positive vision of masculinity have already broken out and become famous in their own right. Fitness influencers like Joe Wicks, whose career began with his Instagram posts as The Body Coach, may not attract teenage boys with their lewd content. Simple advice delivered in a friendly, almost relentlessly cheerful manner can still garner millions of followers.

Perhaps the biggest symbol of this more assertive approach to masculinity is the philanthropic work of Russ Cook, known to many as Instagram’s biggest geek. If all goes to plan, he will complete his year-long attempt to cross the continent from tip to toe, ending in April. Mr. Cook raised around £200,000. running charity and sand blast and amassed nearly 1 million followers across his various social platforms, conclusively proving the appropriateness of his username in the process.

But there’s an asymmetry in some of the debate around toxic influencers, said Saul Parker, founder of. good side, we work with charities and brands to help them achieve their positive goals. While young women are encouraged to seek out positive role models for their own benefit, young men are often encouraged to seek out positive role models in order to treat women better. It risks ignoring the harm that harmful influencers can cause to boys and young people themselves, and undermines efforts to encourage them to find better people to learn from.

“There’s a generation of men who have been born into very difficult conversations about patriarchy and its impact on women’s lives,” Parker says. “As a result, they’re in a place where they feel like they’re third-class citizens. And accepting that young men are having a bit of a hard time and needing help is difficult, especially on the left. It’s very difficult.”


Skip past newsletter promotions

Because focusing on misogyny rather than the broader message of traditional masculine norms in which the “manosphere” thrives risks overshadowing a second generation of post-Tate pernicious influences, this is important. Through repetition, the boys learn that repeating the casual misogyny of someone like Tate in public is bad, and when asked, they say they don’t like the way he talks about women, but say, “Other things.” often insist that you just listen to him.

“David Goggins is the kind of guy we’re facing right now,” Parker said. “He’s a former Navy SEAL, he’s a huge influence on every social platform, but he and all his… The content is about ‘self-discipline’ and ‘self-motivation.’ He tells me things like ‘wake up in the morning,’ ‘go to the gym,’ ‘take a cold shower,’ and ‘be a man,’ but he never talks about women or sex.”

“Taking women out of the equation doesn’t make it any less of a problem. He just doesn’t have anything nasty to say, so it’s hard to find sharp points.”

In other words, attracting boys to a more positive vision of masculinity does not happen by default. But neither should lose hope. There is nothing inherent in childhood experiences that only stick with toxic messages, and with a little work, better role models can develop.

The Age-Defying Power of the New Supercomputer for Your Brain

The human brain is likely the most advanced computer in the world. While it operates differently than a traditional computer and has a much softer structure, its computing power is unparalleled.

Neuromorphic computing, which models machines after the human brain and nervous system, has been a growing concept since the 1980s. Many attempts have been made to achieve this, with the DeepSouth project at the International Center for Neuromorphic Systems at Western Sydney University aiming to be the most advanced yet, with the potential to perform 228 trillion actions per second.

How does a brain computer work?

DeepSouth uses an approach to computing that is inspired by the human brain and body, aiming to combine processing power and memory just like the human brain does. By distributing power to billions of tiny units (neurons) that interact through trillions of different connections (synapses), the brain becomes incredibly powerful while consuming very little energy.

What does this mean for the future of computers?

This approach could lead to significant improvements in energy efficiency and battery life for devices such as smartphones. It could also enable the development of smaller and more powerful computers, bringing high-powered computing to a variety of applications and industries.

How DeepSouth can help fight aging

While the primary goal of DeepSouth is to improve computing technology, the neuromorphic approach also offers insights into the workings of the human brain. This could lead to a better understanding of diseases such as Alzheimer’s, dementia, and Parkinson’s and potentially aid in developing treatments for these conditions.

Neuroscientist Luana Colloca aims to revolutionize pain treatment through the power of the placebo effect

Clove Jetsy; Fierce: Matthew Paul D'Agostino

Despite being a phenomenon known for hundreds of years, there is still much to learn about the placebo effect, which improves health after receiving dummy treatments like sugar pills. It is thought that behind this is the expectation of a positive outcome, and that negative expectations are responsible for the opposite undesirable phenomenon, the nocebo effect, which worsens symptoms. But questions remain about how the mind influences the body in this way and why some people feel its influence more strongly than others.

Luana Colloca are among those grappling with such questions. Colloka, a neuroscientist and director of the Placebo Beyond Opinion Center at the University of Maryland School of Nursing in Baltimore, and colleagues have shown how certain genetic variations shape the extent to which a person responds to a placebo. Ta. They are now studying how best to harness such effects to relieve pain, which could reduce the use of prescription opioid drugs and the risk of addiction to them. They are also exploring the use of virtual reality, with results published last year showing that virtual reality can effectively reduce levels of perceived pain and anxiety.

Tekken 8: The Power of 3D Fighting Explored in New Review

IIt's been nearly 30 years since the original Tekken hit arcades, facing off against Sega's Virtua Fighter and starting a decade-long battle for 3D fighting supremacy. The game's smooth, detailed 3D visuals, engaging characters, and easy-to-access four-button control system brought a new generation of fans to the fighting game genre when it debuted on PlayStation. Subsequent installments in the series have built on that solid track record, although they haven't always had the same impact. . Tekken 7 was a subtle step forward that rewarded dedicated players, but Tekken 8 feels like the first version in a while that truly ups the ante and appeals to newcomers. The result is a thrilling and vibrant video game.

For the uninitiated, Tekken 8 is the latest in a series of fighting games from arcade legends Namco. In this game, a group of brilliantly flashy warriors compete to win the King of Iron Fist tournament in his one-on-one battles in a closed arena. Players fight against increasingly powerful computer-controlled enemies in arcade and story modes, and against each other in local and online competitive matches.

Unlike 2D fighting games such as Street Fighter, characters can not only move on a 2D plane, but also pivot around each other, which adds a sense of depth. The combat system is also very different. In Tekken he uses four buttons, each controlling a different limb, so his basic move set is his two kicks and his two punches, and pressing two at the same time gives you access to a throw. Masu. You can chain button presses into sequences to access more powerful combinations (combos), and pressing both the short and long sides of the D-pad analog stick adds even more force. Tactics range from attacking the opponent with quick jabs and kicks to drain their defenses, to juggling the opponent in the air like a deranged circus performer.

Each fighter has a unique style that combines real martial arts and quasi-magical attacks. There's a ridiculous backstory about the Mishima family during the war, and they're like the Roy family from Succession, but with more wrestling and throwing each other into volcanoes. One of his characters in the game is a giant panda. That's pretty much all you need to know.

If it sounds like a relic from a bygone era, it is and it is not. Tekken 8 is a graphic and technical marvel, and his 32 characters are exquisitely detailed, exquisitely animated, and packed with personality and dignity. In addition to veteran fighters such as the rogue American street fighter Paul Phoenix and the psychic wildlife warden Jun Kazama (returning after a long hiatus), there are also three newcomers: Victor, Reina, and nervous coffee genie Azucena. . Nina Williams in a purple dress with tassels, Sergei Dragunov in high-heeled biker boots, giant cyborg Jack-8 showing off his crushing telescopic fists, all looking incredible That's the feeling.

With so many characters, the characters might feel the same, but there's real diversity here, so whether you're flying through the skies as Alisa Bosconovitch, a beautiful jet-powered android, or Zafina's You can also crawl with creepy tarantulas. The combo gives her a stunning light show of flames and pulsating energy waves. The sound effects that accompany every movement, such as bone-crushing impacts and whiplash sounds, are also fun. The sheer nuclear force of a king suplex or a kick to Li Chaolan's jaw reverberates through the speakers like a crazy Shaw Brothers fight scene at maximum volume.

Critical to Tekken 8's success are two new features: Heat and Arcade Quest. Heat His system, accessed via the right shoulder button, supercharges the fighter for a short period of time, giving them devastating smash moves and ensuring regular attacks do damage even when an opponent is blocking. However, the Heat only have access to him once per game, so timing is everything. Do you activate it early to get a head start, or do you save it as a sort of “get out of nowhere” card for when you’re pushed into a corner?

In the latter situation, Tekken 8 also uses a new interpretation of the Rage system introduced in Tekken 6, which adds extra power to your moves when your health drops below a certain point. In this game, you can also use the character Rage's art. This is an epic super move that will destroy your opponent. My favorite so far is Brian Fury's absolutely crushing storm of mega-punch, culminating in a laser-guided haymaker capable of knocking the moon out of orbit. While Rage doesn't quite match the fighting sim Mario Kart Blue Shell, it does imbue you with a never-say-die attitude that lets you see matches thrillingly turned upside down on the brink of death. .

Then there's Arcade Quest, a sort of narrative role-playing tutorial mode. Create your avatar and travel through the coin-op palace, training key moves and combos while battling non-player characters who offer hints and encouragement. As you win matches and win certain challenges, you unlock new items and rewards, making this a really fun and highly effective way to learn.

It's also a great preview of the online multiplayer mode, which takes your avatar into a vibrant hub world known as the Fight Lounge (which seems like a lot of clubs I've been to), and where you can play with others. You can meet players and challenge them to a duel. There's also a chat system and a place to customize your character and play a light-hearted game of Tekken Ball, your answer to volleyball. I love the attempt to remind me of the arcade atmosphere of the 1980s and 1990s and emphasize friendly competition and camaraderie. Indeed, Tekken 8 producer Michael Murray said, called it “A love letter to arcade culture.”

As someone who has been playing Tekken since 1995, once smashing a PlayStation controller into pieces trying to beat Kazuya Mishima in Tekken 2, and as a young games journalist, I found myself writing for the official PlayStation Magazine. As someone who used to take countless screenshots of Yoshimitsu's helicopter in the game room, Stomp, Tekken 8 is a lot of fun. It's both familiar and new, quirky and intuitive, and accomplishes what all good fighting games do. It feels incredible when you pull off a series of elusive movements with almost ballet-like effect. Tekken was once looked down upon by Street Fighter and Virtua Fighter veterans as a flashy poser, with its combos seen as too automated and unexpressive. But subsequent Tekken titles have added subtle complications, and now in Tekken 8, everyone wants to see how it works.

The King of Iron Fist Tournament is being called. Once again, it's time to answer.

“Tekken 8” has been released

Unlocking the Power of Your Business Data: 4 Ways Azure Cloud Drives Employee Engagement and Customer Insights

As organizations move their computing infrastructure to the cloud, they are harnessing the power of data like never before. Cloud-based services use artificial intelligence (AI) to make data easier to access, search, and understand. Instead of data being the property of a team of data scientists and analysts, new cloud-based tools and technologies are opening up this area of expertise to a wider range of employees across the organization.

Leighton Searle, director of Azure Solutions UK at Microsoft, believes there are significant benefits for businesses running their IT infrastructure. microsoft azure cloud platform. “The huge potential of new generative AI technologies has placed a renewed emphasis on the quality and availability of data in organizations,” he says. When companies move their data to the Microsoft Azure cloud platform, they can instantly access tools and services to unlock their value for both employees and customers. This will lead to culture change and deeper embedding of data throughout the business.

Searle identifies four areas where the cloud is accelerating the use of data, empowering employees, and increasing productivity.

1 Empower employees to make data-driven decisions
Searle emphasized that the cloud is helping to democratize data, allowing employees to access data directly in their daily workflows, rather than being locked into administrative reports or separate line-of-business applications. Masu. “To unlock the value of data and realize its potential, data must be accessible to the people who need it,” Searle said. “It provides contact center agents with a scannable overview of all previous customer interactions, transactions, and support calls, as well as instant access to a company-wide knowledge base of specialized information for world-class That could mean providing a better customer experience or enabling mobile mechanics to meet customer needs. Identifying parts and inventory status from a photo taken with a mobile phone.”

Almost every role can benefit from timely, secure and relevant data, Searle says. When staff become responsible for managing data related to their role, they need tools to simplify the process. Data visualization tools help employees create simple representations of data to glean insights and improve customer experiences.For example, Heathrow Airport Microsoft Power BI Use data visualization tools through Microsoft Teams to transform data from management systems into visualizations that are easy for staff to read. These allow employees to see at a glance how airport passenger numbers are changing in real time. Prepare your staff for the peaks and troughs rather than just reacting to them.

2 Breaking down data silos
To achieve a higher degree of data democracy, data must be made available throughout the organization, rather than being locked away in a central repository. “With the right guidance, governance, and guardrails in place, you can enable the rest of your business and provide access to the data you need,” Searle says.

For example, a group of five south London boroughs formed the South London Partnership; Linked with Azure Build a universal data platform. This includes sharing data from “Internet of Things” (IoT) sensors monitoring at-risk populations, and he estimates the partnership has already saved four lives. I am. IoT sensors also monitor air quality and flood risk. “The ability of cloud technology to share data while maintaining data rights and privacy has allowed us to break down data silos,” Searle says.

3 Building AI and modern search to accelerate your business
Customer and employee expectations have changed as AI-driven experiences play a larger role in daily life. Along with a good data foundation and a good data culture, these experiences are quickly becoming critical to both employee and customer retention. Employees can use internal apps to search for data and access historical information in “structured” tables and graphs or in “unstructured” formats from documents, images, and other sources. You need to dig deep into your knowledge.

Mr. Searle points out that: Azure cognitive search The platform and Azure Open AI service allow users to type common natural language queries into the search bar. This is processed by an AI-powered system that looks at all data sources and returns a natural language summary from the most relevant sources. Used for validation or further research. He says this type of his AI-driven experience will help companies derive insights and make data-driven decisions intuitively and at unprecedented speed.

For example, Cambridge and Peterborough NHS Foundation Trust moved its computing infrastructure to the cloud and used Azure Cognitive Search to Make patient records easier to search By the clinician. The trust has uploaded all records to Azure. The records included all kinds of unstructured data, including handwritten notes, doctor's notes, scanned images, and photographs.

Clinicians said they were “blown away” to learn that Azure Cognitive Search enabled them to discover these diverse formats, allowing them to quickly find handwritten notes and records from the previous year.

4 Building a data-driven culture
From frontline workers to boardroom executives, all employees should be open to incorporating data into the way they work, Searle says. He believes they can all learn from and contribute to enriching the data that flows through them. Employees who are involved in managing their own data are also better placed to reduce the risk of bias and incorrect assumptions in data-driven decision-making.

Searle believes that democratizing data requires a significant change in corporate culture. Departments across the organization, such as human resources, marketing, operations, sales, and finance, play a critical role in the data they generate and consume. For example, business users of organizational data are in the best position to set data security and access policies and manage the data so that it can be used with confidence by other parts of the business.

The pace of change can be daunting for leaders at all levels. To help organizations upskill, Microsoft has partnered with European business school Insead to AI Business School.

Searle outlines the steps businesses need to take to get the most out of their data. “We securely bring data into the Microsoft cloud. We lead from the top to build a data-driven culture across the organization and move quickly to projects that deliver business value. This positive experience ripples throughout the business, and this It will help us incorporate data-driven approaches to further scale.”

On the day the world ended, Renku Sketlish, CEO and founder of Fantail Social Network, sat under a redwood forest in a designated natural beauty spot at dawn and tried to inhale through his navel.

The snow-capped peaks of distant mountains capture the imagination with their curves and crevasses. The nearby trees were maroon for fawns and gray-green for sage. The sequoia's trunk was solid, with cords and twisted vine-like patterns, and its surface was softened by moss and grass. Small insects buzzed around in the dense mass.

“There is no way to really know what's going to happen next,” the instructor said.

Well, it was all a shit show. There was no way to know. Something might happen in the next moment. There might be an opportunity, someone might grab a new idea, or a competitor might try to steal your property. It's also possible that company-stealer Ellen Bywater has Medlar's all-seeing eye in his direction, and her gleaming, elegant hardware is an aspirational alternative to the workaday fantail. Medlar Torc is her new thing, and all her communication needs are handled by this stylish device. She now always seems to be one step ahead of him, seducing his key demographic like she stole Medlar. She may have new products from her, but of course there could also be an earthquake, a sudden heart attack, a deadly bomb released by an unstable dictator far away, or a global pandemic. . anything.

Renku Sketlish was a powerful man who had made a career out of knowing the future, smelling it, and feeling more present around him than the present. The future was his home and his solace. The urgency of tomorrow, the next decade, the next century loomed over him and drove him forward.

“There is no way to know what will actually happen even one second into the future.”

No, that doesn't work for me, thought Renku Sketlish. A low but urgent beep rang out from the thin screen on his wrist. The meditation instructor's brow furrowed, and a satisfying thought occurred to Lenk. Oh, look, there's no way to actually know what's going to happen, right? He glanced at the thin screen. That would be an emergency in Albania or Thailand, a decision to be made, a problem to be resolved, and a wonderful, financially uncontroversial excuse to end the session early. But that wasn't the case. The skin on his face tightened. He narrowed his eyes at the notification. It was no minor escapade. It was the end of days.

We always forget the truth about power. Every generation has learned that it is not the individual, not the office, but power that ultimately irreparably corrupts and distorts even the best characters with the best intentions. I need to be reminded of this again.

I thought about this a lot when writing the novel. future. I've always been interested in writing about power. Most of my books are about how power systems change us and how we change power systems. future It is by far the most powerful individuals on the planet today: those of us who operate, for the most part, without tax or government constraints, without term limits, and who are the “citizens” of their online spheres. We're talking about tech billionaires who operate without having to answer to anything. How did they get there? Why is it so difficult to live outside the infrastructure they have created? And how has it turned them into such centers of power?

There was one book that made a big difference in my way of thinking.

In 1974, Robert Caro published a unique and extraordinary book. power broker. This lifted the lid on Robert Moses, the great builder of New York City's infrastructure (roads, bridges, parks, tunnels, public buildings). Those who knew him personally knew him to be a tyrant and a bully. His plans had long since ceased to make sense except as a means to gain more power.

power broker The book is 1100 pages long, but it is so engaging and engaging that I wish it had a few hundred more pages. This work shows that Moses started out as an idealist. At the start of his career, this is a man who aspired to build diaper changing stations in New York parks, but was so changed by his powers that he ended up suppressing major infrastructure projects became. He cannot be in charge of them. At the back of my copy are questions most readers probably asked themselves as they read on. What did it take? ” Behind that lies another question. How can we detect this early and take immediate action?

Quantum Batteries: Revolutionizing Power Source Technology

Quantum batteries, with their innovative charging methods, are a revolutionary development in battery technology and offer potential for greater efficiency and a broader range of uses in sustainable energy solutions. These batteries use quantum phenomena to capture, distribute, and store power, surpassing the capabilities of traditional chemical batteries in certain low-power applications. A counterintuitive quantum process known as “indefinite causal order” is being used to improve the performance of these quantum batteries, bringing this futuristic technology closer to reality.

Despite being mostly limited to laboratory experiments, researchers are working on various aspects of quantum batteries with the hope of integrating them into practical applications in the future. Researchers, including Chen Yuanbo and associate professor Yoshihiko Hasegawa from the University of Tokyo, are focusing on finding the best way to charge quantum batteries in the most efficient manner.

Using a new quantum effect called “indefinite causal order,” the research team has found that charging quantum batteries can have a significant impact on their performance. This effect has also led to a surprising reversal of the relationship between charger power and battery charging, enabling higher energy batteries to be charged using significantly less electricity. Furthermore, the fundamental principles uncovered through this research have the potential to improve performance in various thermodynamics and heat transfer processes, such as solar panels.

The research paper, titled “Charging Quantum Batteries with Undefined Causal Order: Theory and Experiments,” provides further details on this groundbreaking work and its potential applications in sustainable energy solutions.

really like

heat transfer. He talks about it loudly and proudly, like a preacher in a big tent revival.

“There are several ways to describe energy,” says Beechem, an associate professor of mechanical engineering. “When we talk about light, we describe it in terms of particles called ‘photons.’ Heat also transports energy in a predictable manner. We call these energy waves “phonons.” However, in some materials, photons and phonons can come together to create new objects called “polaritons.” It carries energy in a unique way, different from photons and phonons. ”

Like photons and phonons, polaritons are not physical particles that can be seen or captured. These are similar ways of describing energy exchange.

as if

They were particles.

Still vague? How about another analogy? “Phonons are like an internal combustion engine, and photons are like an electric car,” Beechem says. “Polaritons are Toyota’s Prius. They are a hybrid of light and heat, retaining some of the properties of both. But they are special in their own right.”

Polariton is used in optical applications ranging from stained glass to home health testing. However, their ability to transfer heat has been largely ignored, as the effect becomes noticeable only when the size of the material becomes very small. “We now know that phonons do most of the heat-transferring work,” says Dr. Jacob Minyard. student in Beechem’s lab. “Polariton effects are observable only at the nanoscale. But thanks to semiconductors, we haven’t had to deal with heat transfer at that level until now.”

“Semiconductors have become incredibly small and complex,” he continued. “The people who design and manufacture these chips are starting to realize that phonons do not dissipate heat efficiently at very small scales. Our paper shows that on such length scales polaritons are not very efficient at conducting heat. We have demonstrated that we can contribute to a larger portion of the rate.”

Their research on polaritons was selected as a featured article in a magazine.

The Power of Salt and “Baking” in Addressing Environmental Challenges

Chemists at the University of Copenhagen have made a significant breakthrough in textile recycling by developing an environmentally friendly method to recycle polyester using Harthorn salt. Polyester, which is the second most used fiber in the world, poses a threat to the environment as very little of it is currently recycled. The fabric is a combination of plastic and cotton, making it challenging for the industry to separate and recycle. However, the chemists have discovered a simple solution using a single ingredient found in households.

Polyester is found in various everyday items, such as clothing, sofas, and curtains, with an astonishing 60 million tonnes of the fabric being produced annually. Unfortunately, the production and lack of recycling have a negative impact on the climate and environment, as only 15% of polyester is recycled, while the rest ends up in landfills or incineration, contributing to carbon emissions.

Recycling polyester presents significant challenges, particularly in separating the plastic and cotton fibers without losing them. Traditional methods prioritize preserving the plastic components, resulting in the loss of cotton fibers. These methods are also expensive and complex, with the use of metal catalysts generating harmful waste.

In a revolutionary development, a team of young chemists has found a remarkably simple solution to this problem that could transform sustainability in the textile industry. The researchers have developed a traceless catalytic methodology that allows for the depolymerization of polyester into monomers in an easy and environmentally friendly approach, at a large scale.

The process requires no special equipment and only relies on heat, a non-toxic solvent, and common household materials. By cutting a polyester garment into small pieces and placing them in a container with a mild solvent and Harthorn salt (ammonium bicarbonate), the mixture is heated to 160 degrees Celsius and left for 24 hours. The result is a liquid where the plastic and cotton fibers separate into distinct layers. This simple and cost-effective process preserves the cotton fiber while breaking down the polyester.

The Harthorn salt is broken down into ammonia, CO2, and water during the process. The combination of ammonia and CO2 acts as a catalyst, selectively breaking down the polyester while keeping the cotton fibers intact. The use of ammonia in combination with CO2 is environmentally friendly and safe. Due to the mild nature of the chemical reaction, the cotton fibers remain in excellent condition.

The researchers were pleasantly surprised by the success of their simple recipe for recycling polyester. Although the method has only been tested in the laboratory, the researchers believe it is scalable and are currently exploring partnerships with companies to test the method on an industrial scale. They are determined to commercialize this technology, which has the potential to make a significant impact on textile recycling.
