The Advantages of Group Exercise Over Solo Workouts

“Exercising with peers significantly boosts workout attendance.”

Rich Bowen Photography/Alamy

As a child, I steered clear of team sports; my hand-eye coordination was lacking, and my competitive nature led to more frustration than fun. However, new studies are challenging my perspective. Research indicates that group exercise, particularly in team sports, may provide greater health benefits than going solo.

A 2023 analysis showed that participating in sports—be it for fun or competition—boosts mental well-being, decreasing stress and anxiety levels, and enhancing self-esteem. These outcomes are notably stronger in team sports, suggesting they have a greater positive impact on mental health than other exercise forms, independent of physical activity levels.

The social elements of sports can amplify these physical advantages. Exercising with others increases the likelihood of attending workouts. In a 2024 study, over 770 participants received cash incentives for gym visits, with some required to bring friends. Those with workout partners attended about 35% more often than individuals who could go alone. Follow-up studies suggested this was due to greater accountability and enhanced enjoyment from exercising together.

Other research reveals that this enjoyment can even enhance performance. In one study, participants in a free community run reported feeling more energized when joined by friends or family, resulting in faster paces. Additionally, research on competitive rowers revealed that viewing pictures of loved ones while rowing allowed participants to endure about 20% longer compared to those who looked at images of strangers.

The exact reason remains unclear, but it likely relates to how we process fatigue. Ultimately, our brain governs our muscles, and fatigue serves as a protective mechanism, preventing us from overextending ourselves and risking injuries. Exercising alongside friends (or even just seeing their photos) signals safety to our brains, potentially delaying fatigue.

This concept aligns with a significant shift in exercise psychology, previously emphasizing competition as a performance enhancer. Increasingly, research is exploring the impact of cooperation. After all, our innate ability to run long distances likely developed through collective hunting, suggesting we may be inherently designed to exercise in groups.

This revelation brings me comfort, prompting a shift in focus from competition to collaboration in sports. I’m planning to run a half marathon with my best friend soon, and her suggestion to train together feels like the key to reaching the finish line.

Observing a Group of Young Giant Stars in the Lobster Nebula

Astronomers utilizing the NASA/ESA/CSA James Webb Space Telescope captured stunning new images of the Star Cluster Pismis 24, located in the heart of the nearby Lobster Nebula.

Pismis 24 is located roughly 5,500 light years away from the Scorpius constellation.

This cluster, part of the Lobster Nebula, is the largest known star cluster to date.

“As a vibrant stellar nursery and one of the closest locales for the birth of a massive star, Pismith 24 provides unusual insights into the characteristics of large-scale stars,” Webb astronomers noted in a statement.

“This region serves as an excellent venue for exploring the traits of hot, young stars and their evolutionary paths.”

“It’s remarkable to be at the center of this dazzling cluster Pismith 24-1.”

“Within a mass of stars towering above the jagged orange peak, the tallest spire points directly at it.”

“Initially appearing as a massive single star, Pismis 24-1 was once considered the largest known star.”

“In reality, it comprises at least two stars, which cannot be resolved in a Webb image.”

“With respective masses of 74 and 66 solar masses, the two known stars rank among the largest and brightest ever observed.”

This latest image from Webb’s Nircam (near-infrared camera) reveals thousands of gem-like stars of varying sizes and colors.

“The largest and most astonishing, with six diffraction spikes, is the biggest star in the cluster,” an astronomer commented.

“The numerous small members of the cluster appear as white, yellow, or red, differing by star type and surrounding dust levels.”

Webb also highlights tens of thousands of stars positioned behind clusters that belong to the Milky Way galaxy.

A very hot infant star—almost eight times the temperature of the Sun—creates powerful winds and radiation, shaping a cavity in the walls of the star-forming nebulae.

The nebula far exceeds what Nilkham can observe.

Only a few of these are visible at the bottom right and top right of the image.

“Streams of hot ionized gas from the nebula ridge and a faint veil of star-lit gas and dust surround the towering peak,” the researchers explained.

“A dramatic spire protrudes from the glowing gas walls, resisting the relentless radiation and winds.”

“These spires resemble fingers pointing towards the hot young stars that carved them.”

“The intense forces that shape and compress these spires will likely lead to the formation of new stars within them.”

“The tallest spire measures approximately 5.4 light years from its tip to the bottom of the image.”

“Over 200 solar systems in Neptune’s orbit could fit within its tip, which is 0.14 light-years wide.”

“In this image, cyan represents hydrogen gas that has been heated or ionized by a large young star.”

“Dust molecules akin to Earth’s smoke are depicted in orange. Red signifies cold, dense molecular hydrogen; the darker the red, the thicker the gas. Black indicates dense gas that does not emit light.

NSO Group Ordered to Pay Meta $167 Million in Damages

Israeli cybersecurity company NSO Group has been ordered to pay Meta $167 million in damages, concluding a six-year legal dispute after NSO hacked 1,400 WhatsApp accounts belonging to journalists, human rights activists, and government officials.

In December, U.S. District Court Judge Phyllis Hamilton ruled that NSO had breached cybersecurity laws by using the well-known Pegasus spyware to target mobile phones configured with WhatsApp across 20 countries. Meta, which owns Facebook, Instagram, and WhatsApp, provides an encrypted messaging platform used by over 2 billion individuals.

In March, Meta sought damages from NSO, and last week the court convened to discuss potential penalties. The ruling was made on Tuesday following two days of deliberation.

“Today’s verdict imposing penalties on NSO is a crucial deterrent for the spyware industry against unlawful activities targeting American companies and users globally. This is a threat to the entire industry, and we must all work to safeguard it.”

WhatsApp announced that it would donate the damages to digital rights organizations dedicated to protecting individuals.

“We are excited to share our commitment to providing a variety of services to our users,” stated Gil Rainer, Vice President of Global Communications at NSO Group. “We firmly believe that our technology plays a vital role in preventing serious crimes and terrorism, and is employed responsibly by authorized government agencies.”

WhatsApp initially filed a lawsuit against NSO in 2019, claiming they had accessed WhatsApp servers without authorization. An NSO executive testified about the company’s capability to install Pegasus software on targeted mobile devices without users’ awareness. This executive asserted that Pegasus assists law enforcement and intelligence agencies in combating crime and securing national safety.

Similarly, Apple sued NSO for device hacking in 2021, though it dropped the case in September. Additionally, in 2021, the Commerce Department blacklisted NSO, stating the firm acted “contrary to U.S. national security or foreign policy interests.”

Spyware, a type of software that infiltrates mobile phones, laptops, and other devices, is increasingly used to surveil unsuspecting victims. Initial spyware from NSO required targets to click on links or images sent via WhatsApp, which would then be unintentionally downloaded on their devices.

Evidence presented during the trial indicated that the latest version can penetrate phones through sent text messages without any action needed from the recipient. The proceedings also revealed that NSO has developed technology capable of infiltrating other messaging applications.

John Scott-Railton, an external expert whose work highlights how NSO Group’s spyware targets individuals through WhatsApp, remarked that Tuesday’s decision would adversely affect the company.

“NSO’s operations rely on compromising American companies,” stated Scott-Railton, a senior researcher at Citizen Lab, a cybersecurity watchdog affiliated with the University of Toronto. “Dictators can exploit this to track dissidents. This ruling conveys a strong message.”

Introducing… Anita Dump! The Facebook Group for the Wildest Drug Names – Both Good and Bad!

I distinctly recall the moment I discovered it. Back in university, seated in a plush auditorium that felt slightly uncomfortable. Ping. A notification from Messenger: “Now with LOL,” my best friend texted from 14 kilometers away, without incurring any student debt. I clicked the link.

It was then that I stumbled upon one of the most significant social media communities ever. The Facebook group, simply titled “Drag Name!!!!!,” was vibrant and inviting.

The exuberance in the names and exclamation points speaks volumes. It’s a gathering space for thousands who revel in sharing the cleverest drag queen names.




“When you play with these words, you can almost sense the formation of new gray matter”: A typical post from the Facebook group. Photo: Facebook

It’s organized this way: every day (or whenever creativity strikes), members toss a theme into the mix. Think “biscuits,” “afterlife,” or “unethical.” Then, names start rolling in. For “chocolate,” one participant might suggest Emmanem, another offers Lindor Evangelista, and a particularly clever entry could be she/her.

I felt an immediate spark of inspiration. That day, during the lecture, I realized that no idea of mine could rival the boundless creativity of a 55-year-old man from Missouri.

Some contributions are instantly recognizable. For instance, a photo-inspired name could be Paula Lloyd. Breakfast might yield Shak Shuker, and a humorous take could be Dee Parton for the deceased.

Others require a moment of reflection, and their brilliance becomes even more rewarding. “The Merciful Drug Name” encompasses options like Hildadropen, Karen’s Attention, and Maya L Pue.

I now see clever names everywhere. I sipped my coffee, recalling my favorite: flat white. When writing, I think of myself as a young journalist: Page Turner. After brewing, I might refer to myself as Anita Dump. In this world of words, I can almost feel new gray matter forming, as beneficial to my brain as learning new languages.

A few years back, I had the chance to interview pop sensation Dua Lipa during her visit to Australia for World Pride. I had to ask—did she come up with a drag name for the occasion? If not, how about Duo Apple?


Drag your name!!!!!! It’s a celebration of camp creativity, a blend of humor and joyful expression. The only guideline is to ensure that the name you propose hasn’t been shared before. This allows members to dive into an imaginative realm where they uncover the most delightful creations.

Unlike many groups, this one seems to be devoid of internal conflicts. There’s little risk of harmful disagreements; if they arise, they’ll likely spark even more fantastic names. Try the DEE platform.

Here, individuals from all backgrounds unite around a shared goal: to invent the most captivating names imaginable. Other online communities often lack this spirit of support.

Perhaps drag names embody true community spirit and joy—and what I dare to say is the essence of life? Call me a modern-day Hemingway, as the people truly are the gospel.

Researchers Uncover Potential Strategies for Coping with Dementia, with Insights from Unexpected Group

Can improving brain health be as simple as navigating your way through life? That’s the intriguing question posed in recent research published in the British Medical Journal, which found that being a taxi or ambulance driver may offer protection against dementia.

A study by Harvard researchers examined the working lives and causes of death of millions of Americans and discovered that taxi and ambulance drivers have the lowest incidence of Alzheimer’s disease-related deaths among about 400 different occupations.

The theory suggests that frequent navigation tasks could play a role in protecting against Alzheimer’s disease, which is a significant cause of mortality. In fact, between 2012 and 2021, more people died from dementia in the UK than from any other cause. According to Alzheimer’s Disease Research UK, 75,000 Britons succumbed to the disease in 2023 alone.

Navigating without GPS may help keep your brain sharp – Illustration Credit: Kyle Smart

As we live longer, the risk of dementia increases. The question arises: should we ditch the map app and rely on our natural navigation skills for a longer, healthier life? Previous research has shown that training to become a London taxi driver can actually alter the brain’s structure.

London cabbies, who undergo the rigorous “knowledge” test to master the city’s streets, show an enlargement of the hippocampus, the brain area responsible for spatial processing and navigation. This is significant because the hippocampus is one of the first areas affected by Alzheimer’s disease.

While Harvard’s research suggests that taxi and ambulance drivers have a lower risk of Alzheimer’s disease, it also points out that they tend to have shorter lifespans. This raises questions about the longevity of individuals in these professions and their susceptibility to the disease.

Despite the potential benefits of navigation tasks for brain health, researchers indicate that the study’s findings need to be interpreted within the context of historical mortality data. The widespread use of GPS today could impact the results, as navigation skills may vary among different generations.

Experts like Professor Hugo Spiers of UCL believe that honing navigation skills, especially through outdoor activities, can contribute to overall brain health. Engaging in activities that challenge spatial thinking and physical activity, such as walking in nature, can have positive effects on brain function and may help prevent Alzheimer’s disease.

So, the next time you’re choosing a route, consider stepping outside and navigating your way to improved brain health. Who knows, it might just be the key to a healthier, sharper mind.

About our experts

Hugo Spiers is a professor of cognitive neuroscience at UCL, leading the taxi brain project at the university. His research has been featured in prestigious journals like Nature, Proceedings of the United States Academy of Sciences, and Public Library Science.

Test Your Knowledge: Can You Recognize Your Group Chat After the Signal Leak?

Hey, do you want to send it to your group chat? Likewise, are you sure about 1,000%?

Just check it. It was a strange week in the history of group chats, so it’s a seemingly intimate textual conversation that goes back and forth between friends, family and apparently national security officials.

On Monday, Atlantic Editor-in-Chief Jeffrey Goldberg. I wrote it That he was accidentally added to group chat with encrypted messaging app signals. He announced plans for the attack on the base of Houthi in Yemen, followed when other national security officials came up with plans for the attack after the celebration emoji.

Just as lawmakers on both sides of the aisle condemned the security breaches, Americans were seen as perceived and distrustful with their own unruly group chat.

“It’s clearly a very relevant screw-in,” Goldberg said. Interview With Tim Miller of Bluwork on Tuesday. “We all texted the wrong people,” he added.

However, these careless texts do not contain high-stakes national security information that is usually shared outside of secure government channels.

The incident could be “the most shocking stupid group chat error in history,” said Tommy Beiotter, a liberal podcaster and former National Security Council spokesman. X’s Video. In the same post, he confessed that he was in an email thread that once mistakenly included singer Lyle Lovett in place of his colleague John Lovett. Approximately 30 emails had been sent before anyone noticed.

Group chat has quietly become a staple of modern communication since 2008, when Apple enabled text messaging with multiple recipients. Private group chats award a kind of juicy intimacy to a book club member, a neighbor’s mom, work friends, or a large family who exchanges hundreds of messages per day.

Feeds tend to be less self-conscious than posts on social media. In 2022, a guest essay from the New York Times declared the group chat “leave the last place online for real conversations.”

Even people with no security clearance are aware of what they share with the pleasant familiarity of group chats. Clayton Fletcher, 48, is part of the WhatsApp group, where he and about 35 other comedians roast each other and tackle new ingredients. He is wary high when a new phone number appears. It didn’t appear to happen when Goldberg was added to the signal chat.

“The wisdom of a comedian’s age is to know your audience,” Fletcher said. “In the modern world, I think it’s like knowing who’s in group chat.”

The intimacy of group chats is often elaborate when it spills into the public eye. In 2021, an anonymous leaker shared a group message from Sen. Ted Cruz’s wife, Heidi Cruz, where she planned a trip to Cancun, but millions of members of the senators had no electricity. (Heidi Cruz clearly didn’t understand that group chats didn’t know loyalty,” Jezebel said. read. )

In 2023, the New York Times published a text between the Fox News hosts, which were completely different from the official statement on the 2020 election results. And last year, Daily Beast reported Former House member George Santos texted the humiliation to a group chat that includes members of a New York Republican delegation.

“Sorry, new phone, who’s diss?” Representative Andrew Garbarino I responded.

Our group chats may include people who extend to our professionals and personal lives and who have strong and loose social connections to which we have. It could make them a “minefield” for error, said LM Chilton, author of the upcoming thriller “Everyone in the Group Chat Dies.”

The signal group chat incident was colloquial and especially uncomfortable due to just the tone of Amon Friends (including emojis). And while it may be easy to blame the technology for violations, it was a mistake by national security adviser Michael Waltz to make it accessible to journalists to group chats.

“At the end of the day, it was an artificial mistake and it was with us from the dawn of time,” Chilton said.

New York writer Matt Buquere, 35, found a bit of a dark humor in the way that members of the Signal Group introduced themselves one by one.

Everyone has been added to a group chat where they do not belong to completely. However, he suggested not to stand out unless he was certain he could trust the rest of the group.

“If you have a lot of numbers you don’t know, you should limit group chat participation to thumbs up or ‘haha’ reactions. There’s nothing else,” he said.

Musk-Linked Group Donates $5 Million to Investigate Voter Fraud, Finds Nothing | US Election Integrity

In May 2024, a Fantastic ads Going viral on social media, “There are real cases of fraud and abuse across the country. [election] “The system that erodes our trust.” advertisement The “whistleblower” who shared evidence of election fraud has vowed that he will “reward on payments from the $5 million fund.”

This reward was courtesy of the group that had just been announced. Fair Election Funddocumented documents show that there is a deep connection to Elon Musk’s political network.

The fair election fund “emphasis on these cases” to share their stories with “a large portion of the group’s budget is dedicated to whistleblower payments” and “affective pay and earned.” We have pledged to launch a “media campaign.”

It followed after that Another ad It was run in swing states during the Olympics, telling viewers to share evidence of election fraud, saying, “You might qualify for compensation.”

Despite the group’s high-profile, deep pocket supporters and favorable bounty offers, no evidence of voters or election fraud was revealed. Instead, the group incorporates a series of unrelated detours into tangential areas like third-party voting access, and efforts to reveal fraud have concluded that many research, court decisions, and bipartisan investigations have concluded.

You can do it. The group received funds from the same dark money vehicle that Musk used to guide his political spending, and also routed the funds to another musk-backed nonprofit.

Detours to third-party voting access

The fair election fund’s goal of exposing election fraud at first glance seemed to have no significance.

Elon Musk to lead group in unexpected $100 billion bid for OpenAI

Elon Musk stirred up a dispute between Openai and its CEO Sam Altman on Monday. The billionaire heads a group of investors that revealed they had put forth a $97.4 billion bid for “all assets” of the artificial intelligence company to Openai’s board of directors.

The startup behind ChatGpt is in the process of transitioning from its original non-commercial status. Openai also operates a for-profit subsidiary, and Musk’s unsolicited offer could complicate the company’s plans. Wall Street Journal first reported the proposed bid.

“If Sam Altman and the current Openai, Inc. board of directors are intending to fully focus on profit, it is crucial that the charity is adequately compensated for what its leadership is taking away from it. It’s about time,” stated Mark Toberov, a lawyer representing investors.

Altman quickly responded to Musk shortly after the news broke, stating, “Thank you, but I’ll buy Twitter for $9.74 billion if necessary.” Musk acquired Twitter for $44 billion in 2022 and rebranded it. Musk’s reply to the post was “Swindler.”

Musk co-founded Openai but left the company in 2019 to start his own AI company called Xai. There have been ongoing disagreements between him and Altman over the company’s direction. He sued Openai over its restructuring plan, dropped the lawsuit, and then reignited the conflict.

The bid is backed by Xai and several investment firms, including those managed by Joe Lonsdale, who co-founded Stealth Government contractor Palantir. Ari Emanuel, CEO of entertainment company Endeavor, also joined the group through his investment fund.

“At X.ai, we adhere to the values that Openai has committed to uphold. Grok has fostered open source. We respect the rights of content creators,” Musk stated. “It’s time for Openai to return to its roots of open-source, safety-focused power. We will ensure that happens.”

Toberoff informed the Wall Street Journal that Musk’s consortium of investors is prepared to match or exceed the value of any other potential bids.

Openai argues that the restructuring is crucial for the company’s sustainability and access to capital. They claim that sticking with the non-profit structure alone will not keep up with the highly competitive world of AI innovation. Openai anticipates the restructuring to be completed by 2026.

Musk is a close associate of Donald Trump, whereas Altman met with the president and attended the inauguration. Trump has identified Openai as part of a group of AI companies collaborating on a $500 million deal named Stargate to invest in cutting-edge technology. Musk’s Xai is not included in this agreement.

New Way to Navigate the Housing Crisis: Join a Facebook Group Celebrating Retro Australian Homes and Culture

One of my favorite Facebook group members is someone who shares a dislike for white paint.

In the comments, people discuss old houses from the mid-century era that have been painted white. Some debate whether they can undo the damage caused by previous owners. The focus is on the “incredibly destructive act” of whitewashing these homes, with a link shared to a house that is currently for sale. “I scrolled past three pictures and had to stop,” reads one of the 80 intense replies.

“Unbelievable destructive act”: A white-painted trend that surrounds the beauty of the Middle Ages. Photo: facebook / meta

These are my people and we belong to a retro house for sale group in Australia. This group is dedicated to sharing links to houses from the 1950s, 60s, and 70s (or earlier!) that are currently on the market. We also admire well-maintained vintage beach houses while mourning the tragically renovated interiors that have lost their charm due to new colors.


I may not know what this group is all about, but now it occupies most of my scrolling time and mental space. I find great joy in eavesdropping on discussions about old houses, connecting with strangers over a shared passion. The allure of retro pastel bathrooms and wooden paneling is like a free fashion show. My current favorite discovery is a church converted by Welby. It has a ghostly appearance and sits on 5 acres of land with aging houses around it. In Teac, Victoria, there are remnants of a cult commune or “church-based community” with a “rich heritage,” as delicately put in the listing.

But my obsession goes beyond curiosity. It’s no secret that the Australian housing market is tough, but within this Facebook group, dreams can flourish. I share links to remarkable properties with the group chat, envisioning myself repairing and restoring them.

“Church that looks like a ghost that looks like a ghost” … or a fixer upper that is perfect for this housing crisis. Photo: Realestate.com.au

I skip over listings in pricey Sydney suburbs that are out of reach and focus on fixer-uppers outside the city. I imagine a different life that could have been mine if I had bought one of these homes.

Could I live in a town like Kyogle, NSW, with a population of 2,751? Or perhaps Mount Barker, South Australia? But most of all, I dream of Tasmania with its retro mysteries, affordable prices, and proximity to the beach – if only the water temperature were a bit warmer.

“Can I live in Kaoguru, New South Wales? Population 2,751?” Photo: facebook / meta

This charm is on borrowed time. Retro houses in Australia continue to dwindle as money often triumphs over taste, leading to the demolition of older homes in favor of newer, cheaper options. I witness this reality daily. Despite the construction boom near my beachside Sydney neighborhood, I long for the stories that old houses hold. However, online, I maintain hope that one of these houses can be mine, exchanging thoughts and ideas with others in the group.

Privacy group claims that the gov.uk app could pave the way for a mandatory ID scheme

Privacy athleticist is a new app that emphasizes the risk of using citizens’ driver’s license, passport, and welfare documents as an “essential ID scheme lunch pad”.

Last week, Peter Kyle, a technology secretary, introduced a GOV.UK app and a GOV.UK wallet plan.

These include proof of rights to work in the UK, welfare rights, veteran ID cards, and DBS certificates. This technology incorporates biological authentication security like face scanning. Similar electronic government apps have been implemented in countries such as Poland, Estonia, and Iceland.

Kyle suggests that while paper documents will still be used, the convenience of the app is “inevitable” as more people find it “convincing.” He is working diligently to make this a reality.

Kyle explains that this app features a digital document wallet similar to those found on Apple and Google smartphones, “completely revolutionizing shopping, banking methods, and travel methods.” Ta.

However, the athleticist is now requesting transparency regarding the impacts of new systems on privacy before deployment.

“Kyle may not be in charge of the department for science, innovation, and technology, but the future government may easily utilize optional digital wallets as a fundamental ID scheme launch pad.”

“By including our face recognition data, this vast identity system becomes highly sensitive and tempting for hackers, becoming a honeypot.”

James Baker, Open Rights Group campaign manager, comments:

“Are we heading towards a world that prioritizes convenience? One of the potential concerns is the development of a national identity database where all interactions are monitored.

Kyle unveiled this technology this week with a presentation inspired by Silicon Valley launches. He mentioned that the app will be launched in June, and the wallet will continue to “securely store government-issued digital documents.” The hope is that this app will integrate with various government services, from paying vehicle tax to managing welfare benefits and interacting with NHS.

Authorities are using apps and wallets that are highly secure on modern smartphones, incorporating facial recognition checks similar to those used for digital bank card payments. There is no central database of documents stored in the wallet, requiring hackers to access individual mobile phones.

Skip past newsletter promotions

A government spokesperson explains: “By using the same technology as securing a digital bank card, even if the mobile phone is stolen, access by the thief is not possible, making the digital driver’s license much more secure than a physical copy.

“It is evident that digital identity is not only advantageous but also opens up new possibilities, such as maintaining call centers and in-person support for those requiring assistance with digital services.”

The credentials stored in the wallet should be more challenging to forge than paper documents. Additionally, consolidating numerous essential documents in one place eliminates the risk of losing or damaging physical copies with digital updates and streamlined paperless applications.

It also enhances privacy in certain scenarios, for example, citizens no longer need to reveal their names and addresses when purchasing age-restricted items like alcohol or fireworks.

If this system is outdated or misused, the government reserves the right to revoke qualifications as needed. However, if this is done unjustly, citizens can still utilize paper copies.

Navigating Zoom calls in 2025: Managing small group meetings with stationary backgrounds on the internet

WWhether it’s catching up with colleagues or gathering to set New Year’s resolutions, many of us will be reconnecting via Zoom, Teams, or Google Meet on Monday morning. But while such platforms have revolutionized flexible remote work in recent years, scientists are increasingly realizing that they can have a negative impact on people’s energy levels and self-esteem. So how can you have a healthier relationship with video conferencing in 2025?

Psychologists coined the term relatively early in the pandemic. “Zoom fatigue” Learn about the physical and psychological fatigue that can result from using video conferencing platforms such as Zoom for long periods of time. We found that people who had longer meetings using technology or who had a negative attitude toward meetings were more likely to feel: They made me even more exhausted..

Further research has found that the use of the self-view feature, which allows you to control whether your video is shown on screen during a meeting, is associated with increased fatigue levels. “We also found a gender effect, with women reporting more Zoom fatigue than men,” said Dr. Anna Carolina Queiroz, associate professor of interactive media at the University of Miami in Florida, who has been involved in these studies. says.

An insight from her the study People tend to feel more connected to others through frequent, short, and small group video calls rather than long meetings with many participants. This is likely because it takes longer to maintain nonverbal communication cues, such as eye contact, with many people. A lot of mental effort.

Those who are more sensitive to these communication cues may be more negatively affected, which may explain why women, who often feel greater pressure to present a positive image of themselves on video, tend to feel more fatigued. That could help explain things, Queiroz said.

She suggests keeping online meetings as short and small as possible and taking breaks between meetings to improve cognitive performance.

another the study This suggests that people who spend a lot of time video conferencing may become more conscious of their appearance and may be more likely to report greater dissatisfaction with it. Some people become so preoccupied with perceived flaws that they become anxious about attending gatherings and seek cosmetic surgery to change their appearance.

Dr. George Klompouzos, a professor of dermatology at Brown University and a practicing dermatologist, says, “If you’re worried about imperfections, continued exposure to images of yourself in virtual meetings tends to make those problems worse.” “There is,” he says. “Zoom dysmorphia is at least as common as body dysmorphia, which is a painful or disabling form of perceived or real defect that affects about 2% of the general population.” I’m thinking about it.

Dr. Cemre Turk, a dermatologist and postdoctoral fellow at Massachusetts General Hospital in Boston, US, says that Zoom dysmorphia is very likely to cause an increase in body dysmorphia, which can be devastating to people’s work and personal lives. It said it was important to identify it because it could have an impact. , in collaboration with Kroumpouzos. screening questionnaire It could help identify and treat more such patients.

Even if frequent video conferencing didn’t motivate people to seek facial surgery or “tweaks,” something else did. Recent research suggests It can unconsciously shape purchasing decisions in other ways.

Li Huang, Ph.D., an assistant professor of marketing at Hofstra University in New York, and his colleagues used a combination of eye tracking and surveys to determine how people liked different products after participating in different types of Zoom video calls and in-person meetings. Interest was assessed. Researchers found that video calls increased people’s anxiety about being negatively evaluated by others, whether they realized it or not, and increased their interest in self-help products in the aftermath of the call. It turns out.

Although it may sound negative, “this could actually have some positive consequences,” Huang said. “People are increasingly interested in self-improvement products, but this is not limited to body improvement products such as facial creams, but more general forms such as signing up for a LinkedIn learning course or participating in a health check-up. It also includes self-improvement.

“Most of the time, we are unaware that these types of virtual interactions are affecting our psychological well-being, and we may end up making impulse purchases online without knowing why. By learning about these findings, people can try to reduce these types of impacts.”

For example, the study found that this effect was reduced if study participants were able to turn off their webcams or use ring lights to emphasize their appearance during calls.

Switching to “Speaker View” instead of “Gallery View” and turning off “Self View” can also help, and asking participants to write about their strengths and characteristics after the call can also boost self-esteem. It was helpful.

Another factor that may help reduce the negative effects of video calls is zoom the background Selected. Dr. Heng Chan of Nanyang Technological University in Singapore and his colleagues assessed how tired people felt after video conferencing and found that virtual video backgrounds, such as videos of swaying palm trees or waves crashing on a beach, were associated with feelings of fatigue. I discovered that it does. There is a feeling of fatigue at the highest level, followed by a blurred background. Perhaps this is because the brain is forced to work harder by constantly reacting to new visual information, including the occasional intrusion of unblurred objects, Chan said.

People looking at static virtual backgrounds felt the least fatigued, especially if it was a nature-based image, and another study suggests it may have a calming effect. Masu.

The study didn’t assess the impact of people using real-world backgrounds, but Zhang, who uses backgrounds of trees and mountains for his video calls, said still images were still better. I think it might be better. “If you have your own office, that’s fine, but if you’re in a coffee shop or working outside, there’s a chance that people will be walking behind you or something else will happen that will distract your brain. Yes,” says Chan. “Even if you have your own office, you might be distracted by your personal belongings or worried about what others think of you.”

Huang hopes that in addition to using insights like this to help individuals protect themselves from the negative emotional impact of video conferencing, platforms will also take steps to foster a more positive user experience. I’m here. For example, instead of offering standard beauty filters, you can allow users to adjust lighting and background blur to improve their look more seriously.

“Increasing autonomy over privacy settings, such as controlling who can see and when, could also help reduce the pressure on users to always be visible to many people in meetings,” she said. I say.

Platforms could also consider leveraging artificial intelligence to detect signs of emotional distress in people’s voices and facial expressions, offering features such as discreet breaks and mindfulness exercises to help manage emotions. says Huang.

Elon Musk’s “declaration of war” does not deter anti-hate group from continuing its activities

A British-founded anti-hate speech campaign group involved in Labor’s interference in the US election has pledged to continue its efforts despite Elon Musk’s recent aggressive stance against the party.

The Center to Combat Digital Hate faced criticism from wealthy individuals this week after accusing Musk of violating laws against foreign interference in US elections.

Imran Ahmed, Founder and CEO of CCDH, stated: “We’re not backing down. We will persist in our mission through advocacy and research.”

Musk’s allegations were based on a report that highlighted connections between Labor Together and CCDH, a think tank once led by Keir Starmer’s chief of staff Morgan McSweeney.

Musk shared a report link on his social media platform, claiming, “This is war.” Musk previously attempted unsuccessfully to sue CCDH earlier this year.

President Donald Trump’s campaign filed a complaint against the Labor Party for alleged interference in the election by supporting Democratic candidate Kamala Harris. Mr. Starmer mentioned that party leaders volunteered to assist the Harris campaign in their spare time.

The complaint also mentioned that McSweeney and Downing Street communications director Matthew Doyle attended the Democratic convention in Chicago and met with the Harris campaign team.

In response to Musk’s actions, Mr. Ahmed stated, “Elon Musk has a history of targeting non-partisan organizations like us. This is not the first time we have been attacked by him.”

Mr. Ahmed, a former Labor Party aide, clarified that McSweeney assisted in establishing CCDH but had no operational role in the organization. He emphasized their commitment to their mission and bipartisan collaborations.

Musk’s recent criticism of CCDH followed the publication of an internal report by the organization. Disinformation Chronicle Newsletter revealed that combating misinformation on Musk’s platform was deemed a strategic priority for CCDH.

Mr. Ahmed clarified that ‘Kill Musk’s Twitter’ was used as shorthand to address Musk’s business model, emphasizing their commitment to combating misinformation.

Mr. Ahmed’s background in the Labor Party and his creation of CCDH in response to hate crimes demonstrate his dedication to fighting extremism and misinformation.

Mr. X has been contacted for further comment.

OpenAI claims Iranian group utilized ChatGPT in attempt to sway US elections

OpenAI announced on Friday that it had taken down the accounts of an Iranian group using its chatbot, ChatGPT, to create content with the aim of influencing the U.S. presidential election and other important issues.

Dubbed “Storm-2035,” the attack involved the use of ChatGPT to generate content related to various topics, including discussions on the U.S. presidential election, the Gaza conflict, and Israel’s involvement in the Olympics. This content was then shared on social media platforms and websites.

A Microsoft-backed AI company investigation revealed that ChatGPT was being utilized to produce lengthy articles and short comments for social media.


OpenAI noted that this strategy did not result in significant engagement from the audience, as most of the social media posts had minimal likes, shares, or comments. There was also no evidence of the web articles being shared on social media platforms.

These accounts have been banned from using OpenAI’s services, and the company stated that it will continue to monitor them for any policy violations.

In an early August report by Microsoft threat intelligence, it was revealed that an Iranian network called Storm 2035, operating through four websites posing as news outlets, was actively interacting with U.S. voters across the political spectrum.

The network’s activities focused on generating divisive messages on topics like U.S. presidential candidates, LGBTQ rights, and the Israel-Hamas conflict.

As the November 5th presidential election approaches, the battle between Democratic candidate Kamala Harris and Republican opponent Donald Trump intensifies.

OpenAI previously disrupted five covert influence operations in May that attempted to use their models for deceptive online activities.

A dinosaur from the Pseudopterygota group that inhabited the Panthalassa Ocean’s coast

US paleontologists have described a new genus and species of extinct crocodile relative based on a partially articulated skeleton found in the Middle Triassic Fossil Hill Formation of the Fabre Formation in Nevada, a pelagic region of the eastern Panthalasan Ocean rich in ammonites and giant ichthyosaurs.

Newly identified species Pseudobranchial reptiles It lived during the Middle Triassic period, between 247.2 million and 237 million years ago.

Named Bengwigiwishingasucus Elemical MinisThe animal probably reached a length of around 1.5-1.8 metres (5-6 feet).

It probably stayed fairly close to shore. Its limbs are well developed and well preserved, with no signs of aquatic life such as fins or changes in bone density.

“This intriguing new species provides evidence that pseudobranchs occupied coastal habitats worldwide during the Middle Triassic,” said Dr. Nate Smith, Gretchen Augustine Director and Curator of the Dinosaur Institute at the Natural History Museum of Los Angeles County.

“The area containing the Fabre Formation, which captured fossil life from the Triassic Eastern Panthalassa Ocean, is known for the fossils of marine creatures such as ammonites, as well as marine reptiles such as giant ichthyosaurs. Cymbospondylus youngholm — Newly written Bengwigiwishingasucus Elemical Minis It was a bit of a shock.”

“Our first reaction was, ‘What is this?'” said Dr Nicole Klein, a paleontologist at the University of Bonn.

“We expected to find something like a marine reptile. We couldn’t understand how a land animal could be so far out in the ocean amongst ichthyosaurs and ammonites.”

“It wasn’t until I actually saw the almost perfectly prepared specimen that I was convinced it was indeed a land animal.”

Although pseudopterygian archosaurs have been unearthed from coastal fossil beds in the Tethys Ocean, this is the first to be found in the Panthalassa Ocean and along the coasts of the Western Hemisphere, revealing that close relatives of these crocodiles were present in coastal environments worldwide during the Middle Triassic.

Interestingly, these coastal species do not all belong to the same evolutionary group, suggesting that Pseudobranchia (and Archosaurs more broadly) were uniquely adapted to life along the coast.

“Essentially, it seems like a very different group of archosaurs came together in the Middle Triassic and decided to dip their toes in the water,” Dr Smith said.

“What’s interesting is that many of these ‘independent experiments’ don’t seem to have led to a wider spread of semi-aquatic groups.”

Archosaurs appeared in the Triassic Period and split into two groups, with two representative species surviving: birds, which were descendants of dinosaurs, and pseudo-crocodile archosaurs such as crocodiles (alligators, crocodiles, and gharials). Bengwigiwishingasucus Elemical Minis.

Today’s crocodiles are similar enough to mistake them for other reptiles, but ancient species of crocodiles differed greatly in size and lifestyle.

Evolutionary relationships Bengwigiwishingasucus Elemical Minis and its relatives suggest that pseudobranchs gained great diversity very rapidly after the end-Permian mass extinction, but the extent of this remains to be elucidated in the fossil record.

“The recent and growing number of discoveries of Middle Triassic pseudobranchs suggests that there was underappreciated morphological and ecological diversity and experimentation taking place early in the group’s history,” Dr Smith said.

“Much of the public interest in the Triassic has been focused on the origin of the dinosaurs, but it was the pseudobranchs at the beginning of the Mesozoic that were actually doing interesting things.”

Discovery Bengwigiwishingasucus Elemical Minis It has been reported paper In the journal Biology Letters.

Russian Criminal Group Believed to Be Responsible for Cyber Attack on London Hospital, According to Experts

According to the former chief executive of the National Cyber Security Centre, a Russian cybercriminal group is responsible for a ransomware attack that disrupted operations and testing at a major NHS hospital in London.

The attack on pathology services firm Synovis resulted in a significant capacity impairment and was deemed a very serious incident.

Following the attack, the affected hospital declared a critical situation, halted operations and tests, and was unable to conduct blood transfusions.

A memo sent to NHS staff at multiple London hospitals and primary care services described the incident as a “major IT incident”.

During a BBC Radio 4 interview, Ciarán Martin confirmed that a group of Russian cybercriminals known as Kirin was behind the Synovis attack. These groups operate within Russia, targeting organizations globally for financial gain.

The cybercriminals, who have a history of attacks on various entities, inadvertently caused severe disruption to primary care with their ransomware attack.

While the government’s policy is to refrain from paying ransoms, companies affected by such attacks have the option to do so.

The National Cyber Security Centre is collaborating with NHS authorities to investigate the repercussions of the cyber attack.

Synovis has reported the incident to the police and the Information Commissioner.

Health Secretary Victoria Atkins assured that patient safety is the top priority and efforts are underway to resume services safely.

Synovis CEO Mark Darragh mentioned that a taskforce of Synovis and NHS IT experts is evaluating the impact and necessary measures.

It may take “weeks rather than days” to receive pathology results due to the severity of the attack, as per a senior source cited by the Health Service Journal.

Ransomware group issues warning that UK state is not profitable target | Cybercrime

Ransomware gangs have targeted the UK state after reports emerged that the British Library successfully withstood a damaging cyberattack without succumbing to the demands of the hackers responsible for the ransomware. The library has made it clear that they did not pay any ransom to the attackers or engage with them in any way.

In a statement released as part of their review of the incident, the library emphasized, “The library has not made any payments to the criminals who carried out the attack nor is it associated with them in any way. Ransomware gangs looking to target publicly funded institutions in the future need to be aware of the UK’s national policy as outlined by the NCSC [National Cyber Security Centre], which clearly prohibits such payments.”

Public institutions around the world, including governments, hospitals, schools, and universities, are frequent targets of ransomware attacks. These attacks often involve encrypting or stealing sensitive data and demanding a ransom for its release or to restore access. Prompt ransom payments have been a common response due to insecure cybersecurity practices and the urgent need to restore operations.

The incident report from the British Library highlights that the National Cyber Security Centre is escalating efforts to combat ransomware threats despite previous government discouragement of ransom payments. The aftermath of the attack has left the library operating below capacity, with research services still incomplete months later.

While the library maintains secure copies of its digital collections, the lack of viable infrastructure for restoration has hindered the recovery process. Efforts to combat ransomware have faced challenges with Russia’s withdrawal from international cybercrime cooperation following its invasion of Ukraine.

Recent crackdowns on ransomware gangs by international law enforcement agencies have shown some success, including the seizure of equipment belonging to the Rockbit gang. However, concerns have been raised by the government’s handling of the ransomware threat, with calls for increased attention and resources to address the growing cyber-attack landscape.

Google filed a lawsuit against European media group for $2.3 billion over digital advertising losses

Google, a subsidiary of Alphabet Inc., is facing a 2.1 billion euros ($2.3 billion) lawsuit from 32 media groups, such as Axel Springer and Schibsted. The media groups are alleging losses due to Google’s practices in digital advertising.


The lawsuit comes as antitrust regulators are tightening the grip on Google’s advertising practices. It was initiated by publishers from various European countries like Austria, Belgium, Bulgaria, and more, accusing Google of creating a less competitive market due to its illegal conduct.

The media companies’ lawyers, Geradin Partners and Steck, stated that the losses incurred by the publishers could have been avoided if Google hadn’t abused its dominant position. This could have led to higher advertising revenues for the media companies and lower fees for ad tech services, ultimately benefiting Europe’s media landscape.

The lawsuit is supported by previous actions taken against Google, such as the French competition authority’s fine in 2021 and the European Commission’s complaint last year. Analysts predict that Google may need to adjust its practices and pricing due to increased regulatory scrutiny.

A spokesperson for Google dismissed the lawsuit as “speculative and opportunistic,” emphasizing the company’s collaboration with European publishers to enhance their advertising tools.

Despite Google’s disagreements with antitrust violations, publishers worldwide have expressed concerns about Big Tech’s dominance in advertising and the subsequent decline in their revenue share. Google remains the leading digital advertising platform globally.

The group of media companies chose to file the lawsuit in Dutch courts, citing the country’s reputation for handling antitrust claims effectively in Europe. Companies like Krone, DPG Media, TV2 Danmark A/S, and others are part of the collective seeking legal action against Google.

Hubble spots a group of newly formed stars at the end of a colliding galaxy

Using the NASA/ESA Hubble Space Telescope, astronomers observed seven interacting galaxies with long tadpole-like tidal tails of gas, dust, and numerous stars. Hubble’s exquisite clarity and sensitivity to ultraviolet light led to the discovery of 425 clusters of newborn stars along these tidal tails. Each cluster contains up to a million newborn blue stars.



As seen in this Hubble image, galaxy AM 1054-325 has been distorted from its usual pancake-like spiral shape into an S-shape by the gravity of its neighboring galaxies. As a result, clusters of newborn stars form along tidal tails stretching across thousands of light years, resembling strings of pearls. Image credit: NASA/ESA/STScI/Jayanne English, University of Manitoba.

Tidal tail star clusters have been known for decades. When galaxies interact, gravitational tidal forces pull out long streams of gas and dust.

Two commonly used examples are antennas and rat galaxy It has elongated finger-like projections.

In a new study, astronomer Michael Rodrak of Randolph-Macon College and his colleagues combined new observational data with archival data to determine the age and mass of the tidal tail cluster.

Researchers discovered that these star clusters are very young, only 10 million years old.

And they appear to be forming at the same rate along a tail that extends over thousands of light years.

“It’s surprising that there are so many young objects in the tail,” said Dr Rodrak, lead author of the paper. paper Published in Royal Astronomical Society Monthly Notices.

“It tells us a lot about cluster formation efficiency.”

“With tidal tails, a new generation of stars will be built that otherwise would not exist.”

Tidal tails look like spiral arms of galaxies extending into space.

The outer part of the arm is pulled like taffy by the gravitational tug of war between a pair of interacting galaxies.

Before the merger occurred, galaxies may have been rich in dusty clouds of hydrogen molecules that simply remained inert.

However, during the encounter, the clouds swayed and clashed.

This compressed the hydrogen and triggered the firestorm of star birth.

“The fate of these strung star clusters is uncertain,” the astronomers said.

“They remain intact under gravity and can evolve into globular clusters that orbit outside the plane of the Milky Way.”

“Alternatively, they could disperse and form a stellar halo around their host galaxy, or be thrown off and become stars that wander between galaxies.”

“This pearly star formation may have been more common in the early Universe, when galaxies were colliding with each other more frequently.”

“These nearby galaxies observed by Hubble are proxies for what happened in the distant past, and are therefore laboratories for studying the distant past.”

Unprecedentedly fast radio burst detected in a galaxy group at extreme distance

A fast radio burst phenomenon called FRB 20220610A flashed in an unlikely location: a collection of at least seven galaxies that existed when the universe was only 5 billion years old. Most fast radio bursts to date have been found in isolated galaxies.

This Hubble image shows the host galaxy of the extremely powerful fast radio burst FRB 20220610A. Image credit: NASA/ESA/STScI/Alexa Gordon, Northwestern University.

FRB 20220610A was first detected by the Australian Square Kilometer Array Pathfinder (ASKAP) radio telescope in Western Australia on June 10, 2022.

ESO's Very Large Telescope confirmed that the FRB came from a distant place. The Fed was four times more energetic than its closer counterpart.

“We needed Hubble's acuity and sensitivity to pinpoint the source of the FRB,” said Northwestern University astronomer Alexa Gordon.

“Without Hubble's images, it will remain a mystery whether this arose from a monolithic galaxy or some kind of interacting system.”

“It's these kinds of environments, these strange environments, that are driving us to a deeper understanding of the Fed's mysteries.”

Hubble's sharp images suggest that FRB 20220610A arose in an environment where up to seven galaxies could be on a potential path to a merger, which is also very significant.

“We're ultimately trying to answer the question: What causes this? What are their ancestry and their origin?” said Wen-Fai Fung, an astronomer at Northwestern University. Ta.

“Hubble observations provide an incredible view of the surprising types of environments that give rise to these mysterious events.”

Although hundreds of FRBs have been detected, their ancestry is unknown. One of the leading candidates is magnetars.

They have magnetic fields so strong that if a magnetar were to be located halfway between the Earth and the Moon, it would erase the magnetic stripes on everyone's credit cards around the world.

Even worse, if the astronaut traveled within a few hundred miles of the magnetar, they would effectively be dissolved, as every atom in their body would be destroyed.

Possible mechanisms include some kind of shocking starquake, or an explosion triggered when the magnetar's twisted magnetic field lines break and recombine.

A similar phenomenon occurs on the Sun, causing solar flares, but the magnetar's magnetic field is a trillion times more powerful than the Sun's magnetosphere.

This snap can cause a flash of the FRB or create a shock wave that incinerates the surrounding dust and heats the gas to create a plasma.

There can be several types of magnetars. In some cases, it could be an explosive object orbiting a black hole surrounded by a disk of matter.

Another option is a pair of orbiting neutron stars whose magnetospheres interact periodically to create cavities in which eruptions can occur.

Magnetars are estimated to be active for about 10,000 years before becoming permanent, and are expected to be discovered in areas where violent storms of star formation occur. However, this does not seem to be the case for all magnetars.

In the near future, the sensitivity of FRB experiments will improve and FRBs will be detected at unprecedented rates at these distances.

“We need to continue to find more of these FRBs in different types of environments, both near and far,” Dr. Gordon said.

Astronomers announced that findings in AAS243243rd Meeting of the American Astronomical Society, New Orleans, Louisiana, USA.

Facebook disables previously used PGP-encrypted email, a feature once favored by a niche group of tech enthusiasts

In 2015, as part of a wave to encrypt everything on the internet encouraged by the Edward Snowden revelations, Facebook announced: Allows users to receive encrypted emails from your company..

Even back then, this was a feature for paranoid users. When you turn on this feature, all emails sent by Facebook to users who opt in (primarily like notifications and private messages) will be sent using a decades-old technology called Pretty Good Privacy (PGP). Encrypted.

After eight years, Facebook has discontinued the feature due to low usage, the company said. This feature was retired on Tuesday.

Message Facebook showed users ahead of deprecation of PGP-encrypted email.

Facebook declined to reveal exactly how many users are still using the encrypted email feature. It’s not hard to believe that no one was actually using it. I love encryption, but deprecating this feature makes a lot of sense.

First, you can turn off email notifications completely. The reason is simply that email notifications appear in the Facebook app or browser. Why would he want to get two notifications that a friend tagged you in a photo from a party where you were drunk without asking for permission?

For example, I was using the email encryption feature at the time, but since then I also turned off email notifications, so that feature was useless.

Also, who will be using PGP in the year of the Lord 2023? Even the inventor of PGP, the esteemed cryptologist Phil Zimmerman, has said that he does not use PGP Back in 2015.

“Ironically, I haven’t lost.” Zimmerman told me in an email at the time:.

Zimmerman said the main reason he didn’t use PGP since Symantec acquired PGP in 2010 to incorporate PGP technology into its products was because he couldn’t run the necessary encryption software on his MacBook. He said it was true. Zimmerman also said that “there was no version of his PGP that worked on iOS devices.” (It’s worth noting that you can encrypt email and files on your Mac. GPG Toolsafter its acquisition by Symantec, served as the de facto replacement for PGP (if you want to inflict that kind of pain on yourself).

I’m still using PGP very sometimes.If you want to annoy me, you can use my PGP public key Send an encrypted message. It will be much easier to read and respond if you send it on Signal or WhatsApp instead.

Rest in Peace, Facebook Email Encryption. I never really get lonely.
