The UK's reliance on glyphosate, a widely used herbicide, has come under fire from campaigners who argue that its use has spiralled out of control. Glyphosate, known for its effectiveness in killing weeds, has been linked to various health risks, including cancer, and environmental damage.Originally pioneered by Scottish farmers in the 1980s to dry crops before harvest, the use of glyphosate has expanded globally. In the UK, over 2,200 tonnes of glyphosate were applied in 2024, with more than half used on wheat and other cereals. This represents a 10-fold increase in usage over the past three decades.Despite the World Health Organization classifying glyphosate as 'probably carcinogenic to humans' in 2015, its use has remained high. Bayer, the manufacturer, maintains that its herbicides do not cause cancer, but this stance is contested by many health and environmental organizations.Campaigners, including Nick Mole of Pesticide Action Network UK, are urging the government to phase out and ultimately ban glyphosate, citing its links to a range of cancers and other life-threatening diseases, as well as its impact on the environment. They argue that safer, more sustainable alternatives are available and should be adopted by farmers and local councils.However, some agricultural experts, like Helen Metcalfe of Rothamsted Research, suggest that glyphosate is used differently in the UK compared to the US, where genetically modified crops are involved. The shift towards 'regenerative' farming practices has contributed to the increased use of glyphosate, as it helps protect soil health and prevent erosion.The debate over glyphosate's safety and environmental impact continues, with the EU banning its use in pre-harvest desiccation in 2023 due to concerns about food accumulation. In the US, Bayer has offered $7.25bn to settle lawsuits alleging that Roundup, which contains glyphosate, can cause cancer. The UK government maintains that pesticide use is strictly regulated and only approved if it does not harm human or animal health or the environment.

Peptides are short chains of amino acids that naturally occur in the body, acting as hormones such as insulin, oxytocin and vasopressin, or as fragments released during protein digestion.In recent years, a wave of interest has turned these molecules into purported therapeutic agents for everything from weight loss to anti‑ageing and tissue repair. Prescription drugs like semaglutide (Wegovy) and tirzepatide (Mounjaro) are synthetic peptides that have undergone rigorous clinical testing and are approved for specific medical uses.However, a large portion of the market consists of unregulated, experimental peptides sold for self‑administration. These products often bypass the strict approval processes required for medicines, raising serious safety concerns.Who is using these products? Initially confined to a niche of powerlifters and bodybuilders in the 2010s, the audience has expanded dramatically. Influential figures such as podcaster Joe Rogan have promoted combinations like the “Wolverine stack” (BPC‑157 and TB‑500) for injury recovery, while other compounds—CJC‑1295, MK‑677, ipamorelin, and GHK‑Cu—are marketed for muscle growth and anti‑ageing. Social media platforms are now flooded with instructions on purchasing and injecting these substances.Scientific backing is scant. Reviews of the literature reveal that most experimental peptides have only been tested in animal or cell models. For example, BPC‑157 shows promise for tendon and muscle repair in pre‑clinical studies, but no randomized human trials have validated these effects. Similarly, TB‑4 and its synthetic analogue TB‑500 have demonstrated limited blood‑vessel formation in laboratory settings, yet human data are absent and both are listed as prohibited substances by the World Anti‑Doping Agency.Researchers also highlight a critical knowledge gap: dosage, frequency and treatment duration remain undefined, making self‑administration a gamble.Legal landscape in the UK is clear that peptides not classified as medicines fall outside the Medicines and Healthcare products Regulatory Agency’s (MHRA) remit. If a seller makes medicinal claims, the product must hold a marketing authorisation under the Human Medicines Regulations 2012. The MHRA warns that labeling items as “research use only” does not shield vendors from enforcement when evidence shows the products are intended for human consumption.Health risks are multi‑fold. Experts caution that benefits observed in animal studies do not guarantee safety in humans. Contamination with harmful impurities or bacterial endotoxins can trigger severe reactions, including septic shock. Injecting excess natural peptides may disrupt the body’s tightly regulated hormonal balance, potentially affecting multiple physiological pathways.There is also theoretical concern that augmenting peptide levels could accelerate tumour growth, as some cancers over‑express certain peptide pathways. While no direct cases have been documented, the possibility underscores the need for caution.Additional dangers include improper injection techniques (e.g., air embolism), unknown interactions with existing medications, and the lack of systematic monitoring of long‑term effects. As one researcher put it, “If something goes wrong, users may never notice until irreversible damage has occurred.”

In a bid to reduce greenhouse gas emissions and improve public health, thousands of New Yorkers are making the switch from gas stoves to induction stoves. A recent project in the Washington Heights area of Manhattan has installed induction stoves in 15 co-op apartments, providing residents with a cleaner and healthier way to cook.The project, supported by state and city governments, as well as non-profit groups, aims to reduce the risks associated with gas stoves, including nitrogen dioxide emissions and climate change. According to a study, people who replaced their gas stoves with electric alternatives were exposed to less than half the amount of nitrogen dioxide emissions.Residents, such as Marcos Ramos, are excited about the change. “It makes sense”, he said. “If you’re minimizing risk with the gas, the fire, then environmentally, health-wise, it makes sense. It’s logical.”The induction stoves, supplied by Copper, use magnetic fields to heat cookware directly, making them more efficient and environmentally friendly. The project is part of a larger effort to promote clean energy and reduce greenhouse gas emissions in New York City.Advocates claim that induction stoves are a viable alternative to gas, which has jumped in price amid the Iran war and poses health risks to residents. The city is also working on a $32m pilot to replace gas stoves in 10,000 apartments across the New York City Housing Authority (NYCHA) system.While some states, including New York, California, and Hawaii, are stepping up to promote induction stoves through rebate programs, others are facing resistance from the gas industry and Republican politicians.

A blinking fault light on NASA’s Orion spacecraft signalled a malfunction in the Universal Waste Management System (UWMS) just as the historic Artemis II crew began their 10‑day lunar‑orbit mission. Mission control reported the issue was resolved within minutes, stating: “Happy to report that toilet is go for use. We do recommend letting the system get to operating speed before donating fluid, and then letting it run a little bit after donation.”The $30 million (≈£22.6 million) UWMS, years in development, is hailed as a breakthrough in deep‑space sanitation, dramatically improving on the primitive setups used during Apollo. Back then, astronauts used a condom‑like urine collector and a bagged solid‑waste system that was prone to leaks and even produced “a turd floating through the air,” according to mission transcripts.Orion now features a private toilet cubicle – the first of its kind on a space shuttle – accessed through a floor hatch beside the main entry hatch. Handrails and foot tethers keep the crew anchored while inside.“We’re pretty fortunate as a crew to get a toilet with a door on this tiny spacecraft,” noted Jeremy Hansen of the Canadian Space Agency in a pre‑launch video. “The one place during the mission where we can go and actually feel like we’re alone for a moment.”The system uses a funnel attached to a hose for urine and a small seat for solid waste. Because everything floats, faeces are suctioned into a sealed bag at the bowl’s base and then compressed into a canister. The suction is loud enough that the cubicle is insulated and crew members must wear ear protection while using it.On longer stays, such as ISS missions, astronauts now recycle almost all liquid waste, turning urine and sweat into drinkable water. For the short Artemis II flight, urine will be vented daily and solid waste stored for disposal after return to Earth.Beyond comfort, the upgraded toilet is a mission‑critical component for NASA’s goal of a permanent lunar presence. Sustainable waste handling prevents health risks and avoids contaminating the pristine space environment with Earth microbes. As historian David Munns explained, “Actually thinking about not only toilets but the entire life‑support systems is one of the foundations of long‑term living in space.”

The UK vape industry is sounding the alarm about the proliferation of fake vapes on the market, which can pose serious health risks to users. These counterfeit devices are often sold in high street shops and can look identical to legitimate products, making them difficult to spot.According to the UK Vaping Industry Association (UKVIA), around 5m illegal devices have been seized over the last three years, with a street value of £39m. These devices often lack safety features, such as circuit protection to prevent overheating, which can cause them to catch fire.John Dunne, head of the UKVIA, warns that fake vapes may cause damage to people's health as they have not undergone the same testing regime as legal devices. 'Where the packaging might look similar and the product itself may look similar, these companies may not have the same safety features built into the device, because the copycats tend to try and make the product as cheap as possible,' he says.So, how can you spot a fake vape? One of the key telltale signs is if the box does not have a UK distributor's address on it. Other signs include poor-quality packaging with low-resolution photos or labels, and missing nicotine warnings and ingredient lists. The device name or labelling may also be written in a foreign language.If you suspect that you have bought a fake vape, you can file a report through the UKVIA or contact your local Trading Standards office. You can also check whether a brand has been registered with the MHRA through its website.

Austria is set to introduce a compulsory minimum age of 14 for social media use, with the government citing concerns that certain online platforms are addictive and harmful to young people. The announcement was made by conservative junior minister for digitisation, Alexander Proell, at a joint news conference.“We will decisively protect children and young people in future from the negative effects of social media,” said Vice Chancellor Andreas Babler of the Social Democrats. “We will no longer stand by and watch while these platforms make our children addicted and often also sick … The risks associated with this use were ignored for long enough, and now it is time to act.”The Austrian government plans to draft legislation by June, which will determine which platforms are affected based on their addictive algorithms and content, such as “sexualised violence”. The ban will not target specific platforms but will focus on their impact on young users.This move follows a landmark social media addiction lawsuit in the US, where a jury found Alphabet’s Google and Meta liable for $6m in damages. The case involved a 20-year-old woman who claimed she became addicted to social media apps at a young age due to their platform design. Meta plans to appeal the decision.Other nations in Europe, including France, the UK, Denmark, Spain, and Greece, are also considering or have implemented bans on social media use for children, amid growing concerns about online bullying and mental health risks. The European Parliament has called for the EU to set minimum ages for children to access social media, although it is up to member states to impose age limits.

The UK government is set to trial social media curbs for teenagers in a major study aimed at understanding the impact of reduced social media use on young people's lives. Hundreds of UK teenagers will participate in the six-week pilot, which will test different restrictions on social media use, including bans, digital curfews, and time limits on popular apps like Instagram, TikTok, and Snapchat.The trial, led by the UK government, will involve 300 teens across all four nations of the UK, with some participants having their social apps disabled, while others will have access blocked overnight or capped to one hour's use. The goal is to gather evidence on how different restrictions affect young people's day-to-day lives.Technology Secretary Liz Kendall emphasized the importance of testing different options in the real world, stating that the pilots will provide the evidence needed to take the next steps, informed by the experiences of families themselves.The pilot is part of a broader effort to address concerns about the mental health risks associated with unfettered internet access. Nearly 30,000 parents and children have responded to the government's digital wellbeing consultation, which closes on May 26. An independent study, funded by the Wellcome Trust, will also examine the impact of reducing social media use among adolescents.The study, involving about 4,000 students between the ages of 12 and 15 from 10 Bradford secondary schools, will investigate changes in anxiety and sleep quality, time spent with friends and family, wellbeing, body image, social comparison, school absences, and bullying.The UK government faces pressure to follow Australia's move to ban access to social media sites for under-16s, with France, Spain, and Indonesia also considering similar bans. The European parliament has passed a resolution on age restrictions, although it is not legally binding.Critics argue that the pilot is a half-measure that puts pressure on parents rather than holding big tech accountable for the harm caused by social media. Bereaved parents have written to parliamentarians, urging them to support a ban and expressing concern about the consultation process.

Satellite images of Tehran have revealed that toxic fires caused by Israeli bombings on oil depots were still burning days after the strikes, posing serious health risks to millions of residents in the Iranian capital.The bombings, which occurred on March 7, caused clouds of smoke to blanket the city with pollutants ranging from soot to oil particles to sulphur dioxide. A passing storm then showered Tehran with poisonous, oil-filled rain.Residents have reported headaches, eye and skin irritation, and difficulty breathing. Experts have warned that these symptoms could be just the beginning, with long-term risks of cardiovascular disease, cognitive impairment, DNA damage, and cancer.Four fuel facilities in and around the capital were hit, including the Shahran depot in the north-west, the Aqdasieh oil depot in the north-east, the Tehran refinery in the south, and the Shahid Dolati facility in the west.Satellite images taken two days after the strikes showed the Shahran depot and the Tehran refinery were still burning. Another image taken by the European Space Agency satellite on Tuesday – 10 days after the strikes – showed that those two fires had smouldered, but smoke and flames were visible at the Aqdasieh oil depot.Iran has described the attacks as “ecocide”, which is described as wanton acts of environmental destruction.The United Nations Environment Programme (UNEP) has warned that heavy smoke from burning oil was “directly inhaled by people in Iran – including young children – raising serious concerns about long-term impacts on both human and environmental health”.
