Emergency Measures for Artificial Cooling of the Great Barrier Reef Amidst Warming Surge

Coral bleaching in the Great Barrier Reef off the coast of Queensland, Australia

Researchers stress the urgent need for strategies to artificially provide shade from rising temperatures affecting Australia. This alerts us following recent findings that link changes in transport fuels to an increased risk of coral bleaching.

In recent years, significant sections of barrier reefs have experienced severe bleaching due to rising sea temperatures attributed to climate change.

Adjustments made in 2020 to regulations governing fuel composition have led to additional detriment, according to Robert Ryan from the University of Melbourne. These changes have decreased sulfur dioxide emissions, which are protective pollutants for health, but have also eliminated aerosols that contribute to the cooling of marine clouds over the reefs.

In February 2022, Ryan and his team leveraged computer models to analyze the impacts of cloud cover and solar radiation in relation to fuel emissions over a span of 10 days.

They discovered that emissions at the pre-2020 levels would enhance the local cooling effect of clouds and noted that regulations aimed at reducing sulfate aerosol pollution diminished this cooling effect. Consequently, the new transport fuel regulations led to a rise in sea surface temperatures equivalent to 0.25°C, which created coral bleaching conditions that ranged from 21-40% during the studied period.

“There’s been an 80% reduction in sulfate aerosol transport, likely contributing to conditions that favor coral bleaching in the Great Barrier Reef,” states Ryan.

Bjørn Samset from the International Climate Research Centre in Oslo, Norway, asserts that this study will help address critical inquiries regarding the effects of reduced aerosol pollution on the surrounding environment. “The local aerosol influences may be more significant than previously considered, and we still have limited understanding of their impacts on ocean heat waves,” he remarks.

However, he cautions that the findings illustrate evident links between air quality and the conditions of clouds around notable reef systems, though they only represent a brief timeframe and are complex compared to other related research.

Ryan is also involved in efforts to devise methods to artificially cool coral reefs using Marine Cloud Brightening (MCB), a climate intervention technology that involves dispersing ocean salt particles into the atmosphere to amplify the cooling effects of marine clouds.

Researchers suggest that given their recent findings, such artificial cooling measures for large barrier reefs may be more crucial than ever. “If changes in sulfate emissions have diminished the brightening effects of ocean clouds, it could be worth reconsidering their reimplementation in targeted programs,” Ryan explains.

Daniel Harrison from Southern Cross University in Australia emphasizes that their findings indicate that MCBs can effectively cool the reef, mirroring the cooling effects seen with past shipping emissions. “This study highlights the real-world implications of ongoing changes,” he adds. “It confirms that it was indeed effective.”

Harrison has secured funding from the UK’s Advanced Research and Innovation Agency for a five-year initiative to test the MCB in the Great Barrier Reef, asserting that MCB “aims to harmonize our efforts to lower emissions.”

On the other hand, some experts remain skeptical, arguing that there is insufficient evidence to confirm the safety and efficacy of intentional MCBs. Terry Hughes from James Cook University in Queensland, Australia, has stated that previous trials of MCB were “not successful” and produced no compelling evidence that it can reduce the local sea temperatures of the reef.

IXPE Measures X-Ray Polarization from Magnetic Explosions

A magnetor is a type of neutron star that boasts an extraordinarily strong magnetic field, approximately one times stronger than Earth’s magnetic field. These colossal magnetic fields are believed to be generated when rapidly rotating neutron stars are birthed from the collapse of a giant star’s core. Magnetars emit brilliant X-rays and display erratic patterns of activity, with bursts and flares releasing millions of times more energy than the Sun emits in just one second. Polarization measurements offer insights into magnetic fields and surface characteristics. This was the focus of astronomers using the NASA Imaging X-ray Polarization Explorer (IXPE) to study 1E 1841-045, a magnetor located within Supernova Remnant (SNR) KES 73, situated nearly 28,000 light years from Earth. The findings are published in the Astrophysics Journal Letter.

Magnetors represent a category of young neutron stars. They are the remnants of giant stars that collapsed in on themselves at the end of their life cycles, resembling the mass of the Sun but compressed into a city-sized volume.

Neutron stars exemplify some of the most extreme physical conditions in the observable universe, offering a unique chance to investigate states that cannot be replicated in terrestrial laboratories.

The 1E 1841-045 magnetor was observed in an explosive state on August 21, 2024, by NASA’s Swift, Fermi, and other advanced telescopes.

The IXPE team has permitted several requests to pause scheduled observations of the telescope multiple times each year, redirecting focus to unique and unexpected celestial phenomena.

When 1E 1841-045 transitioned into this bright active phase, scientists chose to direct IXPE to capture the first polarization measurements of the magnetor’s flare.

Magnetors possess magnetic fields thousands of times stronger than most neutron stars, hosting the most powerful magnetic fields among known cosmic entities.

These extreme magnetic field fluctuations can lead to the emission of X-ray energies up to 1,000 times greater than usual for several weeks.

This heightened state is referred to as explosive activity, though the underlying mechanisms remain poorly understood.

IXPE’s X-ray polarization measurements may help unveil the mysteries behind these phenomena.

Polarized light carries information about the direction and orientation of emitted X-ray waves. A higher degree of polarization indicates that the X-ray waves are moving in harmony, akin to a tightly choreographed dance.

Studying the polarization characteristics of magnetors provides clues regarding the energy processes associated with observed photons and the direction and configuration of the magnetor’s magnetic field.

This diagram illustrates the IXPE measurements of X-ray polarized light emitted by 1E 1841-045. Image credit: Michela Rigoselli / Italian National Institute of Astrophysics.

IXPE results, supported by NASA’s Nustar and other telescope observations, indicate that X-ray emissions from 1E 1841-045 exhibit increased polarization at higher energy levels while maintaining a consistent emission direction.

This significant contribution to the high degree of polarization is attributed to the hard X-ray tail of 1E 1841-045, a highly energetic component of the magnetosphere responsible for the highest photon energies detected by IXPE.

Hard X-rays refer to X-rays characterized by shorter wavelengths and greater energy than soft X-rays.

While prevalent in magnetars, the processes that facilitate the generation of these high-energy X-ray photons remain largely enigmatic.

Despite several proposed theories explaining this emission, the high polarization associated with these hard X-rays currently offers additional clues to their origins.

“This unique observation enhances existing models that aim to explain magnetic hard X-ray emissions by elucidating the extensive synchronization seen among these hard X-ray photons,” remarked a student from George Washington University. First paper.

“This effectively demonstrates the power of polarization measurements in refining our understanding of the physics within a magnetar’s extreme environment.”

“It would be fascinating to observe 1E 1841-045 as it returns to its stable baseline state and to track the evolution of polarization,” added Dr. Michela Rigoselli, an astronomer at the National Institute of Astrophysics in Italy. Second paper.

Elon Musk Warns Trump’s Tax Bill Could Undermine Dogecoin’s Cost-Cutting Measures

Elon Musk has openly criticized Donald Trump’s tax plan, asserting that the US president’s financial strategy undermines the cost-saving initiatives implemented by Tesla executives.

These comments from the billionaire entrepreneur were shared with CBS during a comprehensive interview set to air this weekend on Sunday morning. Previews shared on social media included his sentiment saying, “I’m disappointed after witnessing the enormous spending bill that will escalate the fiscal deficit, harming the efforts of the Doge team.”


Musk has been at the helm of the Department of Government Efficiency (DOGE) since January. He later informed that he would step back from the Trump administration in April following a significant drop in Tesla’s revenue.

The proposal now seems to resonate with one major piece of Trump’s legislation, which was passed by the House of Representatives last week.

The legislation fulfills several of Trump’s campaign promises, including extending tax cuts for individuals and corporations while eliminating clean energy incentives established by Joe Biden.

However, the bill also allocates funds for the construction of barriers along the US-Mexico border and includes measures for the large-scale deportation of undocumented immigrants. The Non-partisan Congressional Budget Office predicts the bill will contribute approximately $2.3 trillion (£1.7 trillion) to the deficit, even after considering the tax cuts.

Musk conveyed to CBS:

This comment fuels speculation about a potential rift growing between the billionaire and the president, whom Musk financially supported last year. Altogether, Musk’s Super Political Action Committee contributed $200 million (£148 million) to Trump’s presidential campaign before the elections in November.

Webb telescope measures size of asteroid 2024 YR4 and captures images of potential danger

The destructive forces of shocking asteroids are estimated primarily by knowledge of their size. Near Earth Asteroid 2024 YR4 reached a peak 2032 impact probability on Earth at 3%, motivated the desire to determine its size. Due to its infrared capabilities, the NASA/ESA/CSA James Webbspace Telescope is uniquely suited to such evaluations. Johns Hopkins University astronomer Andrew Livkin and his colleagues used two Webb instruments to measure the diameter for 2024.

These web images show asteroid 2024 YR4 near Earth. Image credits: NASA/ESA/CSA/STSCI/A. RIVKIN, JHU/APL.

2024 yr4 On December 27, 2024, the Asteroid Terrestrial Impact of Río Hurtado was discovered by the Last Alert System (Atlas) station.

The asteroid took a close approach to Earth at a distance of 828,800 km (515,000 miles) two days before its discovery.

Initial observations from the 2024 YR4 showed that the diameter was 40-90 m (131-295 ft).

Dr. Eric McLennan, an astronomer at the University of Helsinki, said:

“However, thermal radiation at infrared wavelengths is a direct indicator of size.”

Dr. Livin, Dr. McLennan and his colleagues observed using the 2024 YR4 Webb’s Near-Infrared Camera (nircam) Mid-infrared instrument (Milli).

Nircam data reflects light, while Miri’s observations show heat light.

“The observations were taken to study the thermal properties of the 2024 YR4, including how quickly it heats and cools at the current distance from the sun, and how hot the heat is,” the astronomer said.

“These measurements show that this asteroid does not share the properties observed on the larger asteroid.”

“This could be a combination of its fast spin and a lack of fine sand on its surface.”

“More research is needed, but this is thought to coincide with surfaces dominated by rocks that are roughly below the size of a fist.”

New Webb observations show that the asteroid measures approximately 60 m (197 feet).

“The 2024 YR4 has been the smallest object that Webb has ever targeted and is one of the smallest objects that directly measure its size,” the researchers said.

“New observations from Webb provide unique information about the size of the YR4 in 2024, as well as complement the ground-based observations of the object’s location to improve understanding of the object’s trajectory and future trajectory.”

Team’s Survey results It was published in AAS research notes.

Italian Police Enhance Security Measures at Tesla Dealerships Following Destruction of 17 Cars in Rome Fire

The Italian Ministry of Interior has instructed police across the country to step up security at Tesla dealerships following a fire in Rome that destroyed 17 electric vehicles manufactured by Elon Musk’s company.

The Digos, an anti-terrorism force within the Italian state police, is investigating whether anarchists were behind the fire at a Tesla dealership in Torre Angela, a suburb of Rome.

Firefighters spent hours extinguishing the flames early Monday. Drone footage showed a line of charred vehicles in the dealership’s parking lot. Musk referred to the incident as “terrorism” on his social media platforms.

Italy is home to 13 Tesla dealerships managed by the parent company, with most located in cities like Rome, Florence, and Milan.

A source within the interior ministry indicated that they are alerting authorities to the possibility of anti-Tesla protests amidst a global trend of vandalism in response to Musk’s political involvement in the US. Surveillance at dealerships will be increased as needed.

Since Donald Trump’s presidency began, Musk has reduced government employees as part of his “government efficiency” initiative, leading to the establishment of the “Tesla Takedown” boycott movement that started in the US and spread to Europe.

While most protests have been peaceful so far, Tesla dealerships and vehicles are increasingly becoming targets of vandalism. In Germany, seven vehicles were vandalized at dealerships in Ottersburg, and in Sweden, two Tesla stores—one in Stockholm and another in Malmö—were destroyed with orange paint.

Musk has fostered ties with far-right leaders in Europe, such as Italian Prime Minister Giorgia Meloni, who praised him as “a great man.” Matteo Salvini, leader of the far-right league in Italy, expressed solidarity with Musk following the incident in Rome.

“There is unwarranted animosity towards Tesla,” Salvini stated.

Laid off NOAA employees warn of potential impact on weather forecasts and safety measures

A scientist with a Ph.D. issues tsunami alerts and serves as a Hurricane Hunting Flight Director. Researchers investigate communities that are prone to flooding during storms.

They were part of over 600 workers who were laid off last week by the Trump administration, resulting in around a 5% reduction in the workforce of the National Weather Service and the National Oceanic and Atmospheric Administration (NOAA).

Kayla Besong, a physical scientist at the Tsunami Warning Center, was one of the affected employees. She played a key role in the safety monitoring team, which was reduced from 12 members to 11. She was responsible for programming a system that assessed the risk to the U.S. coastline and issued alerts accordingly.

The layoffs have raised concerns about the impact on public safety programs and the ability to deal with the increasing frequency of weather disasters due to climate change. Last year alone, NOAA recorded a $27 billion disaster that resulted in 568 deaths in the U.S., marking the second-highest death toll since 1980, accounting for inflation.

Meteorologists are facing challenges and criticism, despite their improving accuracy in predicting weather events. The Trump administration’s decision to cut jobs at NOAA has been met with protests and legal challenges. Experts warn that these cuts threaten progress and could hinder crucial scientific advancements.

NOAA has declined to comment on the layoffs, emphasizing its commitment to providing timely information and resources to the public. Former agency officials argue that the cuts jeopardize public safety, especially during weather emergencies.

Congressional Democrats have also opposed the layoffs, citing the impact on public safety and the ability to provide accurate weather forecasts. The cuts have affected essential roles, such as hurricane modeling specialists and flight directors, who play a vital role in predicting and responding to severe weather events.

The reduction in NOAA’s workforce has sparked concerns about the agency’s ability to effectively respond to upcoming weather seasons, potentially putting lives at risk and undermining public safety efforts.

UK ratifies first international treaty on AI regulatory measures

The UK government has joined the first international treaty on artificial intelligence in a bid to prevent its misuse, such as the dissemination of misinformation or the use of biased data for decision-making.

The agreement, known as the Framework Convention on Artificial Intelligence, requires countries to implement protections against any threats AI may pose to human rights, democracy, and the rule of law. Drafted by the Council of Europe, the treaty was signed by the EU, UK, US, and Israel on Thursday.

According to Attorney General Shabana Mahmood, AI has the potential to enhance public services and drive economic growth, but its implementation should not compromise fundamental human rights.

Mahmood stated, “This treaty is a significant step in ensuring that these new technologies can be utilized without undermining our core values, such as human rights and the rule of law.”

Here we present an overview of the treaty and its implications for the use of AI.

What is the objective of this convention?

The Council of Europe aims to address any legal gaps that may arise due to rapid technological advancements. Recent advancements in AI have prompted a global effort to regulate the technology and mitigate potential risks.

The treaty requires AI systems to adhere to principles such as protecting personal data, non-discrimination, safe development, and respect for human dignity. Governments must implement safeguards to prevent AI-generated misinformation and biased data training that could lead to erroneous decisions.

Who is included in the treaty?

The treaty applies to the use of AI by both public authorities and the private sector. Companies and organizations using relevant AI systems must assess their impact on human rights, democracy, and the rule of law and make this information publicly available. Individuals should have the right to challenge AI decisions and file complaints with authorities.

How will this be enforced in the UK?

The UK will need to ensure that existing laws, such as the European Court of Human Rights and other human rights legislation, cover the treaty’s provisions. The government is planning to introduce a new AI Bill for consultation.

Once the treaty is ratified and enforced in the UK, it will enhance existing laws and measures, according to the government.

In terms of enforcement, authorities may prohibit certain uses of AI. For example, EU AI law prohibits systems using facial recognition databases obtained from CCTV or the internet, as well as systems that classify individuals based on their social behavior.

For the First Time, NASA’s Endurance Mission Measures Earth’s Bipolar Electric Field

First hypothesized over 60 years ago Bipolar electric field Polar winds are the primary driver of a constant outflow of charged particles into space above the Earth’s poles. These electric fields lift charged particles in the upper atmosphere to higher altitudes than usual, and may have shaped the evolution of Earth in ways that are still unknown.



Collinson othersThey report that a potential drop of +0.55 ± 0.09 V exists between 250 km and 768 km due to the planetary electrostatic field, generated solely by the outward pressure of ionospheric electrons. They experimentally demonstrate that the Earth’s ambipolar field controls the structure of the polar ionosphere, increasing its scale height by 271%. Image courtesy of NASA.

Since the 1960s, spacecraft flying over Earth’s poles have detected streams of particles streaming from Earth’s atmosphere into space.

Theorists predicted these outflows, named them polar winds, and stimulated research to understand their causes.

Some outflow from the atmosphere was expected — intense, unobstructed sunlight should send some atmospheric particles escaping into space, like water vapor evaporating from a pot of water — but the observed polar winds were more puzzling.

Many of the particles inside were cold and showed no signs of heating, but they were moving at supersonic speeds.

“Something must be attracting these particles to the outer reaches of the atmosphere,” said Dr. Glynn Collinson, Endurance mission principal investigator and a researcher at NASA’s Goddard Space Flight Center.

The electric fields, hypothesized to be generated at subatomic levels, would be incredibly weak and their effects would be expected to be felt only for distances of hundreds of miles.

For decades, detecting it has been beyond the limits of existing technology.

In 2016, Dr Collinson and his colleagues began inventing a new instrument that they thought would be suitable for measuring Earth’s bipolar magnetic field.

The team’s equipment and ideas were perfectly suited for a suborbital rocket flight launched from the Arctic.

The researchers named the mission “Antarctic Expedition,” in honor of the ship that carried Ernest Shackleton on his famous 1914 Antarctic voyage. Endurance.

They set course for Svalbard, a Norwegian island just a few hundred miles from the North Pole and home to the world’s northernmost rocket launch site.

“Svalbard is the only rocket launch site in the world that can fly through the polar winds and make the measurements we need,” said Dr Susie Ingber, an astrophysicist at the University of Leicester.

Endurance was launched on May 11, 2022, reaching an altitude of 768.03 kilometers (477.23 miles) and splashing down in the Greenland Sea 19 minutes later.

Over the 518.2 kilometres (322 miles) altitude where Endurance collected data, it measured a change in electrical potential of just 0.55 volts (V).

“Half a volt is almost meaningless – it’s about the strength of a watch battery – but it’s just right for describing polar winds,” Dr Collinson said.

Hydrogen ions, the most abundant type of particle in the polar wind, experience an outward force from this field that is 10.6 times stronger than gravity.

“That’s more than enough to counter gravity, in fact to launch you into space at supersonic speeds,” said Dr. Alex Grosser, a research scientist at NASA’s Goddard Space Flight Center and Endurance project scientist.

Heavier particles are also accelerated: an oxygen ion at the same altitude, immersed in this 0.5 volt electric field, loses half its mass.

In general, scientists have found that bipolar magnetic fields increase what’s called the scale height of the ionosphere by 271%, meaning the ionosphere remains denser up to higher altitudes than it would be without the bipolar magnetic field.

“It’s like a conveyor belt that lifts the atmosphere up into space,” Dr Collinson said.

The Endurance discovery has opened up many new avenues of exploration.

The polarity field, as a fundamental energy field of the Earth alongside gravity and magnetism, may have continually shaped the evolution of the atmosphere in ways that we are only now beginning to explore.

Because it is generated by the internal dynamics of the atmosphere, similar electric fields are expected to exist on other planets, including Venus and Mars.

“Any planet with an atmosphere should have a bipolar magnetic field, and now that we’ve finally measured it we can start to learn how it has shaped our planet and other planets over time,” Dr Collinson said.

UK government deliberates on retaliatory measures against Russian hackers responsible for theft of NHS records

According to The Guardian, the government is contemplating a response to Russian hackers who obtained records of 300 million NHS patient interactions, including sensitive data like HIV and cancer blood test results.

The National Crime Agency (NCA) is exploring potential actions against the Russia-based ransomware group Qilin, who recently leaked the stolen NHS records in a cyber attack on June 3.

Healthcare leaders in London, where the attack occurred, set up a helpline to address concerns from worried patients about their data and advised against contacting hospitals or GP practices directly for information.

The NCA and the National Cyber Security Centre are discussing possible responses to the ransom demand of $50 million, which has so far been ignored, prompting concerns about the severity of the attack.

Experts from the NCA are working to remove the data leaked by Kirin on the messaging platform, but the extent of the damage and the potential impact of retrieving or deleting the data remain uncertain.

Authorities have dealt with similar ransomware gangs previously, including taking down the LockBit group with international cooperation, showcasing their commitment to combatting cyber threats.

The recent attack on the NHS reveals a major breach in patient data security, affecting multiple hospitals and healthcare facilities, leading to cancellations and disruptions in medical services.

Patients are cautioned to be vigilant against potential scams targeting them based on the leaked data and are advised to report any suspicious activity to the appropriate authorities immediately.

The NHS Helpline is available for patients seeking information or assistance related to the incident, and efforts are being made to minimize the impact of the data breach on patient care.

The release of private healthcare test records along with NHS data indicates a broader breach that could have far-reaching implications, underscoring the need for enhanced cybersecurity measures in the healthcare sector.

Despite ongoing challenges, healthcare providers are striving to maintain essential services for patients while addressing the fallout from the cyber attack on the NHS.

Cybersecurity experts stress the importance of swift action in response to data breaches, indicating that negotiations with ransomware groups typically end once data is leaked.

While the situation remains precarious, authorities and healthcare institutions are working diligently to mitigate the impact of the attack and prevent further breaches in the future.

California requires indoor workers to adhere to heat stroke prevention measures

summary

  • California is set to implement state-first regulations aimed at protecting indoor workers from the heat.
  • The policy, which could go into effect later this summer, would require employers to provide water, breaks, and places to cool down if indoor temperatures reach 82 degrees Fahrenheit.
  • The only other states that mandate similar protections are Oregon and Minnesota.

California is poised to pass the state’s first regulations to protect people who work indoors from extreme heat, a policy that could take effect as soon as later this summer.

The California Department of Occupational Safety and Health (Cal/OSHA) Standards Committee unanimously voted Thursday to approve heycircle circleOak Place RulesThis will send the standards to the state’s Office of Administrative Law for quick final approval, meaning the standards could go into effect by early August.

The heat plan was originally scheduled to go into effect in 2019 but faced a five-year delay. If enacted into law, the policy would protect about 1.4 million warehouse workers, restaurant employees, manufacturing workers, and other indoor workers from dangerously hot working conditions.

The regulations require employers to monitor employees for heatstroke and provide hydration, breaks, and cool areas if indoor temperatures reach 82 degrees Fahrenheit. If temperatures reach 87 degrees Fahrenheit, employers must take further measures, such as providing more breaks, adjusting work schedules, slowing down work pace, and providing air conditioning.

If these rules go into effect, California would join Oregon and Minnesota as the only states with policies to protect indoor workers from the heat. In 2006, California passed heat standards for outdoor workers, including those in agriculture and construction.

Meanwhile, in Texas and Florida, recent state laws have weakened workplace protections against extreme heat by prohibiting cities and counties from enacting local regulations to protect outdoor workers, such as requiring water breaks or time in the shade.

Labor advocates have been pushing for national workplace heat standards for indoor and outdoor workers, but the federal Occupational Safety and Health Administration has yet to adopt such rules.

Advocates say California-style regulations are needed more urgently than ever as heat waves become more frequent and intense due to climate change.

“This is huge,” said Anastasia Nicole Wright, policy manager at WorkSafe, a non-profit worker advocacy group based in Oakland, Calif. “Workers need these protections as soon as possible.”

But the state’s new requirements don’t protect all indoor workers. For now, they exempt employees of state and local correctional facilities, as well as other prison staff. In March, Gov. Gavin Newsom’s administration revised the standards to exempt the state prison system, questioning how much it would cost to bring the California Department of Corrections and Rehabilitation into compliance with the requirements.

Some labor advocates believe the temperature standards set in California’s policy are still too high.

“The risk of heatstroke depends on both temperature and humidity, but it also has a lot to do with physical demands,” says Tim Shaddix, legal director for the Warehouse Workers Resource Center, an advocacy group based in Ontario, Calif. “If a warehouse worker is lifting heavy boxes for an eight- or 10-hour shift, they’re at risk for heatstroke even when temperatures are in the high 70s.”

Shaddix added that he hopes California’s restrictions will inspire other parts of the country to implement similar rules.

“As summer temperatures rise due to climate change, the problem is only going to get worse, so it’s really important that we see progress and we see more models that encourage other states to follow,” he said. “And that’s the push at the federal level, and we really need that, because we have to make sure that workers across the country are protected.”

More people die from heatstroke each year in the United States than from any other extreme weather event. In 2022, 43 people died from exposure to ambient heat in the workplace, up from 36 in 2021. According to the U.S. Bureau of Labor Statistics.

Robert Mootrie, senior policy advocate at the California Chamber of Commerce, said California employers are “moving into compliance mode,” but added that certain industries, such as restaurants, will bear a greater burden because kitchens are essentially hot, enclosed spaces.

Mootrie also said small businesses in particular have expressed concerns about how to best implement the rules when they come into effect in just a few months.

“It doesn’t take much to change your internal practices, train your staff, and talk to your lawyers,” he said. “All of these things take time and resources.”

Regarding workers in California prisons and jails, Cal/OSHA said in a statement that it plans to “proceed with proposing industry-specific regulations for local and state correctional facilities that take into account the unique operational realities of these workplaces,” but did not provide a specific timeline.

Wright expressed disappointment that tens of thousands of prison staff are exempt from the restrictions.

“They’re a big percentage of the workforce,” she said, “but heat is an issue for workers and non-workers alike. Many prisons don’t have central air conditioning, so forcing prisons to take certain measures to ensure temperatures inside prisons are safe for workers would benefit inmates as well.”

Light and sound therapy may provide preventative measures against chemically-induced brain changes in Alzheimer’s disease

Some cancer treatments can cause so-called chemobrain, commonly defined as problems with memory and concentration.

One Bar/Alamy

An experimental treatment for Alzheimer’s disease that involves flickering lights and low-pitched sounds may also help prevent cognitive impairment after cancer treatment, also known as chemical brain, a study in mice suggests.

In the case of Alzheimer’s disease, light and sound stimulation has been shown in small human trials to reduce memory and concentration problems, but larger studies are still investigating it.

The light flashes 40 times per second, or 40 Hz, and the sound also has a frequency of 40 Hz. This frequency was originally chosen because the brainwave intensity of Alzheimer’s patients is lower than 40 Hz and is associated with memory processing. The idea was that this treatment would stimulate these brain waves.

Subsequent research has shown that such brain waves may have a wide range of benefits for the brain, including increased immune cell activity and, more recently, strengthened drainage systems that may help remove a toxic protein called beta-amyloid. It suggests that there is.

Cai Li Hui The Massachusetts Institute of Technology researchers who developed this approach thought it could help cancer patients who have memory and concentration problems after chemotherapy and other cancer treatments. It is thought that these may be caused by damage to brain cells, but the exact mechanism is unknown and there is no cure.

In the latest study, Professor Tsai’s team exposed cancer-free mice to light and sound for one hour a day while being given a common chemotherapy drug called cisplatin, compared to those who had just received chemotherapy. They found that they experienced less decline in mental acuity than mice.

Acuity was assessed by a memory test in which mice were exposed to either new or familiar objects, and the animals typically showed more interest in things they had never seen before. Chemotherapy reduced the mice’s ability to identify objects, but this was prevented by light and sound treatment.

The therapy had several effects, including reducing inflammation in the brain, reducing DNA damage, and reducing the loss of myelin, the insulation around nerve cell fibers.

nazanin derakshan Researchers at Britain’s University of Reading say the idea needs to be tested in people to see if it has any overall benefits. If this treatment is given at the same time as chemotherapy and reduces cell death in the brain, it may help cancer cells survive there, she says.

Meta Accused of Inadequate Child Protection Measures by Whistleblower

According to a whistleblower, Mark Zuckerberg’s Meta Inc. has not done enough to protect children following Molly Russell’s death. The whistleblower claimed that the social media company already poses a risk to teenagers and that Zuckerberg had put in place infrastructure to protect against such content.

Arturo Bejar, the owner of Instagram and Facebook, voiced his concern that the company had not learned from Molly’s death and could have provided a safer experience for young users. Bejar’s survey of Instagram users revealed that 8.4% of 13- to 15-year-olds had seen someone harm themselves or threaten to harm themselves within the past week.

Bejar stressed that if the company had taken the right steps after Molly Russell’s death, the number of people encountering self-harm content would have been significantly lower. Russell, who committed suicide after viewing harmful content related to suicide, self-harm, depression, and anxiety on Instagram and Pinterest, sparked the whistleblower’s concerns. Bejar believes that the company could have made Instagram safer for teens but chose not to make necessary changes.

Former Meta employees have also asked the company to set goals for reducing harmful content and creating sustainable incentives to work on these issues. Meanwhile, Béjart has met with British politicians, regulators, and activists, including Ian Russell, Molly’s father.

Bejar has suggested a series of changes for Meta, including making it easier for users to flag unwanted content, surveying users’ experiences regularly, and facilitating the reporting of negative experiences with Meta’s services.

For those in need of support, various crisis support services and helplines are available in different regions. The Samaritans, National Suicide Prevention Lifeline, and other international helplines are accessible for anyone in need of assistance.

OpenAI enhances safety measures and grants board veto authority over risky AI developments

OpenAI is expanding its internal safety processes to prevent harmful AI threats. The new “Safety Advisory Group” will sit above the technical team and will make recommendations to management, with the board having a veto right, but of course whether or not they actually exercise it is entirely up to them. This is a problem.

There is usually no need to report on the details of such policies. In reality, the flow of functions and responsibilities is unclear, and many meetings take place behind closed doors, with little visibility to outsiders. Perhaps this is the case, but given recent leadership struggles and the evolving AI risk debate, it’s important to consider how the world’s leading AI development companies are approaching safety considerations. there is.

new document and blog postOpenAI is discussing its latest “preparation framework,” but this framework is based on two of the most “decelerationist” members of the board, Ilya Satskeva (whose role has changed somewhat and is still with the company). After the reorganization in November when Helen was removed, Toner seems to have been slightly remodeled (completely gone).

The main purpose of the update appears to be to provide a clear path for identifying “catastrophic” risks inherent in models under development, analyzing them, and deciding how to deal with them. They define it as:

A catastrophic risk is a risk that could result in hundreds of billions of dollars in economic damage or serious harm or death to a large number of individuals. This includes, but is not limited to, existential risks.

(Existential risks are of the “rise of the machines” type.)

Production models are managed by the “Safety Systems” team. This is for example against organized abuse of ChatGPT, which can be mitigated through API limits and adjustments. Frontier models under development are joined by a “preparation” team that attempts to identify and quantify risks before the model is released. And then there’s the “superalignment” team, working on theoretical guide rails for a “superintelligent” model, but I don’t know if we’re anywhere near that.

The first two categories are real, not fictional, and have relatively easy-to-understand rubrics. Their team focuses on cyber security, “persuasion” (e.g. disinformation), model autonomy (i.e. acting on its own), CBRN (chemical, biological, radiological, nuclear threats, e.g. novel pathogens), We evaluate each model based on four risk categories: ).

Various mitigation measures are envisaged. For example, we might reasonably refrain from explaining the manufacturing process for napalm or pipe bombs. If a model is rated as having a “high” risk after considering known mitigations, it cannot be deployed. Additionally, if a model has a “severe” risk, it will not be developed further.

An example of assessing model risk using OpenAI’s rubric.

These risk levels are actually documented in the framework, in case you’re wondering whether they should be left to the discretion of engineers and product managers.

For example, in its most practical cybersecurity section, “increasing operator productivity in critical cyber operational tasks by a certain factor” is a “medium” risk. The high-risk model, on the other hand, would “identify and develop proofs of concept for high-value exploits against hardened targets without human intervention.” Importantly, “the model is able to devise and execute new end-to-end strategies for cyberattacks against hardened targets, given only high-level desired objectives.” Obviously, we don’t want to put it out there (although it could sell for a good amount of money).

I asked OpenAI about how these categories are being defined and refined, and whether new risks like photorealistic fake videos of people fall into “persuasion” or new categories, for example. I asked for details. We will update this post if we receive a response.

Therefore, only medium and high risks are acceptable in any case. However, the people creating these models are not necessarily the best people to evaluate and recommend them. To that end, OpenAI has established a cross-functional safety advisory group at the top of its technical ranks to review the boffin’s report and make recommendations that include a more advanced perspective. The hope is that this will uncover some “unknown unknowns” (so they say), but by their very nature they’ll be pretty hard to catch.

This process requires sending these recommendations to the board and management at the same time. We understand this to mean his CEO Sam Altman, his CTO Mira Murati, and his lieutenants. Management decides whether to ship or refrigerate, but the board can override that decision.

The hope is that this will avoid high-risk products and processes being greenlit without board knowledge or approval, as was rumored to have happened before the big drama. Of course, the result of the above drama is that two of the more critical voices have been sidelined, and some money-minded people who are smart but are not AI experts (Brett Taylor and Larry・Summers) was appointed.

If a panel of experts makes a recommendation and the CEO makes a decision based on that information, will this friendly board really feel empowered to disagree with them and pump the brakes? If so, do we hear about it? Transparency isn’t really addressed, other than OpenAI’s promise to have an independent third party audit it.

Suppose a model is developed that guarantees a “critical” risk category. OpenAI has been unashamedly vocal about this kind of thing in the past. Talking about how powerful your model is that you refuse to release it is great advertising. But if the risk is so real and OpenAI is so concerned about it, is there any guarantee that this will happen? Maybe it’s a bad idea. But it’s not really mentioned either way.

Apple’s latest update includes security measures to protect stolen phones from hacking attempts by thieves

This is the perfect protection against hacking attacks.

Have you ever felt dizzy thinking your phone might be stolen? There’s no need to worry. Apple has devised a powerful new weapon in the fight against cybercrime. It’s a new IOS update called Stolen Device Protection that prevents thieves from accessing your smartphone with stolen passwords.

“In rare cases, a thief can steal your device by watching you enter your passcode, but Stolen Device Protection adds a sophisticated new layer of protection,” an Apple spokesperson said, says the person. said in a statement.

This bold new security feature, released Tuesday as an iOS 17.3 developer beta, is especially useful when users change their Apple ID password, remove Face ID, or remove other sensitive features. , requires the use of a biometric access code such as a face or fingerprint.

Whenever a user’s device is in an unfamiliar location, stolen device protection is initiated and the user is then required to complete the aforementioned protocol.


“In the rare case that a thief steals your device by watching you enter your passcode, Stolen Device Protection adds a sophisticated new layer of protection,” an Apple spokesperson said. Masu. Denphoto – Stock.adobe.com

As an additional safeguard against “smash-and-grab” operations, users must re-enter their data after an hour to confirm the change, effectively rendering any passcode hacking attempt futile.

Stolen Device Protection is currently only available to beta testers, but will be available to all users once Apple releases the final version of iOS 17.3. TechCrunch reported.

An Apple spokesperson said the move is part of an ongoing campaign to protect smartphone users “as threats to user devices continue to evolve.”

Last month, the release of a new iPhone feature, NameDrop, set off alarm bells. This allows a user to instantly share contact information with his iPhone or Apple Watch nearby, instead of physically handing the phone over to someone.

While it did speed up the information exchange process, viewers became concerned that users were unknowingly sharing their information with unknown iPhone users.
