Researchers caution that the implementation of AI models in scientific laboratories poses risks, potentially leading to dangerous experiments that could result in fires or explosions. While these models offer a convincing semblance of understanding, they might lack essential safety protocols. Recent testing on 19 advanced AI models revealed that all of them are capable of making critical errors.

Although severe accidents in academic laboratories are uncommon, they are not unheard of. Chemist Karen Wetterhahn tragically lost her life in 1997 due to dimethylmercury penetrating her protective gloves. In another incident in 2016, a researcher suffered severe injuries from an explosion; and in 2014, another scientist was partially blinded.

AI models are increasingly being utilized across various industries, including research institutions, for experiment and procedure design. Specialized AI tools have demonstrated success in various scientific sectors, such as biology, meteorology, and mathematics. However, general-purpose models often generate inaccurate responses due to gaps in their data access. While this may be manageable in casual applications like travel planning or cooking, it poses life-threatening risks when devising chemical experiments.

To assess these risks, Zhang Xiangliang, a professor at the University of Notre Dame, developed LabSafety Bench, a testing mechanism that evaluates whether an AI model can recognize potential dangers and adverse outcomes. This includes 765 multiple-choice questions and 404 scenario-based illustrations that highlight safety concerns.

In multiple-choice assessments, some AI models, like Vicuna, scored barely above random guessing, while GPT-4o achieved an 86.55% accuracy rate, and DeepSeek-R1 reached 84.49%. In image-based evaluations, models like InstructBlip-7B demonstrated less than 30% accuracy. The team evaluated 19 state-of-the-art large-scale language models (LLMs) and vision-language models and found that none surpassed a 70% overall accuracy.

Although Zhang expresses optimism about the future of AI in scientific applications, particularly in “self-driving laboratories” where robots operate autonomously, he underscores that these models are not yet equipped to plan experiments effectively. “Currently? In the lab? I don’t think so. These models are primarily trained for general tasks, such as email drafting or paper summarization, excelling in those areas but lacking expertise in laboratory safety,” he states.

An OpenAI representative commented, “We welcome research aimed at making AI safe and reliable in scientific settings, particularly where safety is a concern.” They noted that the recent tests had not included any of their major models. “GPT-5.2 is the most advanced scientific model to date, offering enhanced reasoning, planning, and error detection capabilities to support researchers better while ensuring that human oversight remains paramount for safety-critical decisions.”

Requests for comments from Google, DeepSeek, Meta, Mistral, and Anthropic went unanswered.

Alan Tucker from Brunel University in London asserts that while AI models may prove incredibly useful for aiding human experiment design, their deployment must be approached cautiously. He emphasizes, “It’s evident that new generations of LLMs are being utilized inappropriately because of misplaced trust. Evidence suggests that people may be relying too heavily on AI to perform critical tasks without adequate oversight.”

Craig Malik, a professor at UCLA, shared his recent experience testing an AI model’s response to a hypothetical sulfuric acid spill. The correct procedure—rinsing with water—was contrary to the model’s repeated warnings against it, which instead offered unrelated advice about potential heat buildup. However, he noted that the model’s responses had improved in recent months.

Malik stressed the necessity of fostering robust safety practices among new students due to their inexperience. Yet he remains more optimistic than some peers about the role AI could play in experimental design, stating, “Are they worse than humans? While it’s valid to critique these large-scale models, it’s important to realize they haven’t been tested against a representative human cohort. Some individuals are very cautious, while others are not. It’s conceivable that these models could outperform a percentage of novice graduates or even experienced researchers. Moreover, these models are continuously evolving, indicating that the findings from this paper may be outdated within months.”

Mosquitoes Are Poised to Become More Hazardous in the UK and US: Here’s Why

I woke up with a multitude of itchy red bites. And? Most likely, it’s those pesky mosquitoes that are causing the irritation. While they aren’t the sole culprits for the marks left behind, the redness is actually a reaction to the saliva from those tiny, blood-sucking insects.

Globally, there are around 3,500 mosquito species, including 36 in the UK and over 200 in the US, with only the females being the notorious bloodsuckers.

Mosquitoes are widely recognized as nuisances. Even in regions like the UK and the US, where concerns over diseases such as malaria, dengue, and Zika are minimal, it’s important to be aware of their potential threats.

However, Professor James Logan urges us to take these creatures seriously. He is the Dean of the London School of Hygiene and Tropical Medicine’s (LSHTM) School of Disease Control and the CEO of Arctech.

“As climate change progresses, more mosquitoes capable of transmitting diseases are encroaching closer to the UK and the US, including not just malaria-carrying mosquitoes but those that spread dengue as well,” he states.

“Currently, there are no active disease outbreaks, but that won’t be the case for long. It’s not a question of ‘if,’ but rather ‘when.’”

According to Logan, the US is “even further ahead” in this regard, with cases of dengue, malaria, and the West Nile virus on the rise.

In May 2025, the UK Health Security Agency reported the first detection of the West Nile virus within British mosquitoes.

Regardless of potential disease threats, mosquito bites tend to be a common nuisance every summer, with scant scientific evidence to support any immediate concerns.

In the UK, the National Health Service (NHS) has noted an uptick in visits to pages about “insect bites and stings,” indicating a rise in the number of people reporting bites in recent years.

“The warmer weather might encourage mosquito reproduction and activity, leading to more of them being around,” Logan mentions.

Why do mosquito bites itch?

As the weather heats up, the mosquito population rises—so what makes their bites so bothersome?

It all boils down to the mosquito’s mouthparts, slender and needle-like, designed for sucking.

“Mosquitoes are drawn to your scent, warmth, and moisture. When they alight on you, they insert their mouthparts into your skin,” Logan explains. “The tip of the mouthpart navigates around, seeking a blood vessel, and once it finds one, it feeds from there.”

In the process of feeding, these unwelcome intruders inject saliva into your bloodstream to prevent clotting and numb pain, allowing them to go undetected.

However, the chemicals they inject can trigger an allergic response, resulting in those itchy red welts.

“When bitten by a particular mosquito species for the first time, the reaction is generally mild,” states Logan. “With repeated bites, your body becomes sensitized, and the reactions may become stronger. Continuous exposure can further adapt your immune system.”

Your immune system treats substances like mosquito saliva as threats, prompting white blood cells to produce antibodies. Consequently, your body reacts with redness or swelling during subsequent encounters.

This process is known as sensitization, akin to how allergies develop. Fortunately, regular exposure—termed desensitization—can reduce your response over time.

In seasonal regions, the intermittent summer exposure to mosquitoes means our bodies take longer to acclimatize.

How to keep mosquitoes at bay

Now that we’ve identified the problem, how can we prevent mosquito bites? While closing windows and donning long clothing are effective strategies, they may not be appealing during hot summer days.

You might consider installing insect screens or mosquito nets in your sleeping areas.

“Removing breeding grounds is also crucial,” Logan advises, as mosquitoes thrive in stagnant water—anything deeper than a bottle cap can serve as ideal breeding conditions. Ensure to cover water sources such as flowerpots, buckets, and bird baths, and eliminate any trash or recyclables that might gather water.

In addition, wearing insect repellents is advisable. Logan praises DEET (N,N-diethyl-M-toluamide) as “one of the best repellents available,” affirming its safety when applied according to product instructions.

If you prefer a natural alternative, consider using Lemon Eucalyptus oil, noted also as OLE or PMD. Other options include IR3535 and picaridin.

Some essential oils have shown promise; a 2023 study found that clove, cinnamon, and geraniol oils can be effective.

Despite this, Logan cautions, “reliance solely on natural solutions may not be sufficient.”

If you’re willing to invest further, consider “impregnated” clothing—this doesn’t refer to anything sensational but involves fabric treated with insect repellents or insecticides, typically permethrin.

“We also have plug-in devices that distribute pesticides throughout our homes,” Logan adds, “which can eliminate pests like spiders and flies that venture inside.”

What to do if bitten

If you’ve already fallen victim to a mosquito bite, here are some tips to manage the situation.

“The first rule is not to scratch,” Logan advises, acknowledging the challenge. “Scratching only risks infection.”

In severe cases, mosquito bites could lead to serious infections, sepsis, or even limb amputation, Logan warns.

If a bite is particularly bothersome, you may consider over-the-counter antihistamines or hydrocortisone creams, although their effectiveness can vary.

“They may work wonders for some, while others experience little relief,” he notes. “Antihistamine creams need to be applied immediately after being bitten due to the rapid production of histamine.”

“Unfortunately, many people delay addressing the bite, making timely intervention essential.”

In summary, Logan emphasizes:

Researchers have discovered a method to eradicate hazardous “eternal chemicals” lurking in your household

For over 70 years, chemical compounds known as “Forever Chemicals” have been used in various products, ranging from non-stick cookware to food packaging. Despite their widespread use, these chemicals have been linked to serious health risks, including certain types of cancer. Recent scientific advancements have led to the development of new methods for breaking down and recycling these seemingly permanent materials, prompting a need for alternative names.

Mark Ruffalo, a fan of the 2019 film Dark Waters, is well aware of the environmental and health hazards posed by per- and polyfluoroalkyl substances (PFAS).

The difficulty in removing PFAS has been a significant challenge until now. Researchers from Oxford University and Colorado State University have collaborated to create a novel technique for not only destroying PFAS, but also recovering valuable components from it.

“The breakthrough in using phosphates to destroy PFAS represents a significant advancement in addressing longstanding environmental concerns,” stated Dr. Longyan, a chemist at Oxford University and the lead author of the study published in Nature.

“Through this effective PFAS destruction method, we aim to shift away from referring to these compounds as ‘Forever Chemicals’.”

So, how was this achieved? The scientists treated PFAS samples with potassium phosphate salts and mechanically ground the mixture using ball bearings to break the strong carbon-fluorine bonds present in PFAS and extract the fluorine content for other applications.

This process is crucial as fluorine is primarily sourced from a mineral called Fluorspar, which is used in various industries including pharmaceuticals and agriculture.

Professor Véronique Gouverneur, the Oxford chemist leading the study, emphasized the significance of recovering fluoride for essential drug production, highlighting the impact of large-scale mining on depleting this resource.

This innovative approach not only addresses the removal of PFAS but also enables the recycling of components to support other industries, making it a potentially beneficial solution for multiple sectors.

Astronomers Discover Fewer Potentially Hazardous Asteroids Near Earth than Initially Predicted

astronomer using Zwicky Temporary Facility (ZTF) investigated. Taurus resonance groupa large interplanetary system containing Comet 2P/Encke, several meteor showers, and possibly numerous near-Earth asteroids.

“We can take advantage of the unique opportunity that this asteroid swarm has to approach Earth to more efficiently search for celestial objects that may pose a threat to Earth,” said Dr. Kuanji Ye, an astronomer at the University of Maryland. ” he said.

“Our results suggest that the risk of impact from large asteroids in the Taurus group is much lower than we thought, which is good news for planetary defense.”

Prior to this study, astronomers had predicted that the Taurus resonance complex contained a significant number of large kilometer-sized space rocks, probably left behind by large objects up to 100 kilometers (62 miles) wide. I was guessing.

If a large object were to hit Earth, like the Chelyabinsk asteroid in 2013, it could cause regional damage.

Even larger objects can cause extinction-level events, like the asteroid that wiped out the dinosaurs more than 66 million years ago.

“Fortunately, we found that there are likely only a small number of asteroids in this large size class, perhaps only nine to 14, in this population,” Dr. Ye said.

“Judging by our findings, the parent object that first spawned the swarm was probably closer to 10 km (6.2 miles) in diameter, rather than a giant 100 km diameter object.”

“We still need to be cautious about asteroid impacts, but knowing this result will probably help us sleep better.”

The Taurus swarm holds important clues about planetary evolution, especially because of its association with Comet Encke.

This comet has the shortest orbital period of any known comet, at just 3.3 years.

It is also unusually large and dusty for a short-period comet that orbits the sun within 200 years.

Considering all available evidence, scientists believe that Encke has experienced significant fragmentation in the past and may continue to do so in the future.

“Studying the Taurus swarm helps us understand how small objects like comets and asteroids form and break up over time,” said Dr. Ye.

“Our research has implications not only for asteroid detection and planetary defense, but also for our broader understanding of the solar system's celestial bodies.”

The researchers presented their findings. findings this week's DPS56Annual Meeting of the Planetary Science Division of the American Astronomical Society.

Tesla facing lawsuit from 25 California counties over alleged mishandling of hazardous waste

A group of 25 California counties has sued Elon Musk’s Tesla, accusing the electric car maker of mishandling hazardous waste at its facilities in the state.

The lawsuits from Los Angeles, Alameda, San Joaquin, San Francisco and other counties were filed Tuesday in California state court. The company is seeking civil penalties and an injunction that would require it to properly dispose of its waste in the future.


Tesla did not immediately respond to a request for comment.

The counties accused Tesla of violating the state’s Unfair Business Practices Act and Hazardous Waste Management Act by improperly labeling the waste and sending the material to landfills that cannot accept hazardous materials. California’s Hazardous Waste Management Act can result in civil penalties of as much as $70,000 per day for each violation.

The waste generated or processed at the facility includes paint materials, brake fluid, used batteries, antifreeze, diesel fuel and more, according to the county.

The complaint alleges violations occur at 101 facilities, including Tesla’s manufacturing plant in Fremont. Spokespeople for each county did not immediately provide additional details about the incident.

The lawsuit is not the first time Tesla has faced allegations related to its hazardous waste management practices.

The company reached a settlement with the U.S. Environmental Protection Agency (EPA) in 2019 over alleged federal hazardous waste violations at its Fremont plant. In that agreement, Tesla agreed to take steps to properly manage waste within its facilities. and pay a $31,000 fine..

Tesla subsequently filed a lawsuit with the Environmental Protection Agency in 2022 after federal officials alleged it failed to maintain records and implement plans to minimize air pollutants from paint operations at its Fremont factory. They reached an agreement and agreed to pay a penalty of $275,000.
