A 47‑year‑old woman who had endured three life‑threatening autoimmune diseases for more than a decade is now living a near‑normal life after an experimental CAR‑T cell therapy reset her immune system at University Hospital Erlangen in Germany.Before the procedure she had exhausted nine different treatments with no lasting benefit, relying on daily blood transfusions and continuous anticoagulation to manage her illnesses.Within weeks of the infusion, doctors observed rapid improvement in all three conditions—a world‑first outcome. She has remained in treatment‑free remission for 14 months and has largely returned to everyday activities.Prof Fabian Müller, who led the team, called the speed and depth of the response “remarkable” and said the therapy “significantly improved her quality of life.” He emphasized that clinical trials are required to determine how durable the effect is and whether it can help other autoimmune patients.The patient suffered from three distinct disorders: autoimmune haemolytic anaemia (AIHA), where rogue immune cells destroy red blood cells; immune thrombocytopenia (ITP), which depletes platelets and raises bleeding risk; and antiphospholipid syndrome (APS), which promotes dangerous blood clots. All three stem from malfunctioning B‑cells.With no conventional options left, doctors turned to CAR‑T therapy, a technique that has revolutionised treatment for certain cancers. They harvested her white‑blood cells, isolated the T‑cells, engineered them to recognise the CD19 protein on B‑cells, and reinfused the modified cells.The engineered T‑cells swiftly eliminated the pathogenic B‑cells. She received her last blood transfusion a week after treatment and was able to perform routine tasks within two weeks. Follow‑up tests showed a reconstituted, healthy B‑cell population, suggesting an immune reset. The findings were published in the journal Med.She still exhibits a mildly low white‑cell count and slightly elevated liver enzymes, which researchers attribute to the cumulative impact of prior therapies rather than the CAR‑T product.Rheumatology expert Prof Ben Parker of Manchester University NHS Foundation Trust described the case as encouraging, noting that “the prolonged response off normal therapy suggests there has been an immune reset.” However, he warned that case reports alone cannot confirm efficacy and highlighted ongoing trials for lupus, myositis, multiple sclerosis, systemic sclerosis, vasculitis, and other autoimmune conditions.

Researchers have made a significant breakthrough in understanding why weight-loss medications, such as GLP1 receptor agonists, work better for some individuals than others. A recent study published in Nature has identified genetic variations in two genes involved in gut hormone pathways that regulate appetite and digestion. These genetic variations may help account for different weight-loss results or side-effects when taking glucagon-like peptide 1 (GLP1) medicines, which mimic natural gut hormones to regulate appetite, insulin release, and digestion. The study analyzed data from 27,885 patients on GLP1 drugs and found that specific genetic variants were associated with slightly more weight loss or side-effects like nausea and vomiting. The findings suggest that genetic differences may contribute to why people respond differently to weight-loss jabs. However, the overall impact of genetics appeared to be modest, with non-genetic factors such as sex, drug type, dose, and duration appearing to explain a substantially larger proportion of variability. The study's results reinforce that while there is substantial variability in response to GLP1 therapies, genetics is only one part of a much more complex picture. According to Marie Spreckley, an obesity expert at the University of Cambridge, the study provides plausible evidence that genetic variants could affect outcomes. However, she notes that the magnitude of these genetic effects is small in clinical terms, and that behavioral, clinical, and treatment-related factors remain the dominant drivers of outcomes. The study's authors suggest that their findings could support future efforts to use genetic information when making treatment choices for obesity. However, Spreckley cautions that the evidence is not yet sufficient to support using genetic information to guide treatment decisions in routine clinical practice.

Researchers at Rothamsted Research in Harpenden, Hertfordshire, have made a groundbreaking discovery in the field of food safety. By utilizing Crispr genome editing, they have successfully developed wheat that can be used to make bread with reduced levels of acrylamide, a toxic compound classified as a probable carcinogen.The innovation lies in the reduction of free asparagine, an amino acid in wheat that converts into acrylamide when bread is toasted, fried, or baked. Field trials over two years demonstrated that gene-edited wheat can have significantly lower concentrations of free asparagine without impacting crop yields. This translates into lower acrylamide formation in food products, making toasted bread safer for consumption.In tests, bread and biscuits made from the edited wheat showed substantially reduced acrylamide levels, with some bread samples having concentrations below detectable limits even after toasting. The Crispr editing targeted the gene responsible for asparagine production, achieving a reduction of up to 93% in free asparagine in dual-edited lines.Compared to conventional methods that achieved a 50% reduction in free asparagine but resulted in a 25% yield penalty, the Crispr-edited wheat offers a more efficient and effective solution. Dr. Navneet Kaur, a lead researcher, highlighted the potential of Crispr technology to deliver precise, beneficial changes in crop genetics, emphasizing the importance of supportive regulatory frameworks to unlock benefits for agriculture and food systems.The UK has become a global hub for gene editing research since Brexit, with the Genetic Technology (Precision Breeding) Act of 2023 facilitating the development and marketing of genetically modified crops. However, the future of these advancements may be influenced by negotiations with the EU over sanitary and phytosanitary agreements.Prof. Nigel Halford, who led the study, noted that low-acrylamide wheat could help food businesses meet safety standards without compromising product quality or incurring major costs, ultimately reducing consumers' dietary exposure to acrylamide.

Renowned artist and stage designer Es Devlin is pioneering a unique approach to addressing AI ethics through her latest project, which combines ceramics and collaboration. At the AI and Earth conference organized by Devlin, a diverse group of artists, AI researchers, spiritual leaders, academics, and tech experts gathered at Oxford Kilns to discuss AI and create pottery.The conference, held in preparation for the opening ceremony of the Schwarzman Centre for the Humanities at Oxford University, aimed to foster dialogue and understanding among individuals with varying perspectives on AI. Devlin's approach emphasizes the importance of human connection and hands-on engagement in the digital age.Participants, including Alan Turing and Isaac Asimov, discussed the implications of AI on society, while Ethan Mollick introduced his concept of centaurs or cyborgs, describing how humans use AI for specific tasks or close collaboration. The event also featured a performance by the University Chamber Choir and a choral piece by Nico Muhly, inspired by the works of 17th-century theologian and poet Thomas Traherne.Devlin's installation, 360 Vessels, will be showcased at the Schwarzman Centre's opening festival, featuring 360 pots created by participants and the public. The project serves as a platform for exploring the intersection of technology, art, and human values.As Devlin noted, 'I am aware that my art and my words and my every choice, my presence, is being used to train the algorithms that concentrate wealth among a small number of individuals, and, in spite of this – however confusing, however painful – I would like to try to stitch my digital shadow back on to my feet and dance with it myself, and invite others to dance with it too.'

Satellite‑imaging firm Planet Labs confirmed it will indefinitely suspend the distribution of visuals covering Iran and the wider Middle East conflict zone, responding to a direct request from the United States government.The California‑based company communicated the decision to its customers via email on Saturday, stating that the administration had asked imagery providers to impose an “indefinite withhold of imagery.”This restriction builds on a 14‑day delay introduced last month, which itself extended an earlier 96‑hour hold. Those temporary measures were intended to prevent hostile actors from exploiting commercial satellite data to target U.S. and allied forces.Planet Labs will withhold all imagery captured since March 9 and expects the policy to stay in place until the end of the war, which began on Feb. 28 when the United States and Israel launched aerial strikes against Iran. Since then, the conflict has escalated, with Iran firing missiles and drones at Israeli and U.S. assets and striking civilian infrastructure throughout the Gulf region.Founded in 2010 by former NASA scientists, the company said it will shift to a “managed distribution” model, releasing images only on a case‑by‑case basis for urgent, mission‑critical needs or when deemed to serve the public interest.“These are extraordinary circumstances, and we are doing all we can to balance the needs of all our stakeholders,” Planet Labs said in its statement.Satellite technology remains vital for military operations—supporting target identification, weapons guidance, missile tracking, and communications. Some space analysts warn that Iran could still access commercial imagery through adversarial channels, while journalists and researchers rely on such data to monitor hard‑to‑reach areas.

In December and January, researchers from the Bob Brown Foundation recorded the unmistakable call of the swift parrot – the world’s fastest bird – in a section of the Wielangta forest, southeast Tasmania, that had already been earmarked for clear‑felling.Dr Charley Gros, a lead scientist on the project, described the call as “tiny but very loud, sharp and quick,” making it easy to distinguish from other forest sounds. Over a two‑month period, the team – assisted by volunteer citizen scientists – logged 68 separate observations, which were later vetted by a government scientist and uploaded to the state environment department’s database.Gros argued that the frequency of detections indicated the area was being used for foraging and nesting, not merely as a fly‑by corridor. “If they’re there every day, that is their habitat,” he said.When the recordings were submitted, the Forest Practices Authority dispatched an ecologist to the site (identified as coupe WT003E) on 10 February. The official report stated that “no swift parrots were observed breeding in the harvest area.” By that time, the forest patch had already been cleared, which Gros noted made the absence of birds unsurprising.The logging operation was carried out by Sustainable Timber Tasmania (formerly Forestry Tasmania). The agency maintained that it operated “within Tasmania’s strict forest‑practice framework” and that “nesting trees are retained and harvested areas are regenerated as native forest,” asserting compliance with environmental regulations.The incident revives a broader debate over whether existing legislation adequately safeguards threatened species. Critics point to the swift parrot’s precipitous decline – a CSIRO‑published guide in 2021 estimated the population at about 750 individuals, down from roughly 2,000 a decade earlier – and warn that without stronger protection the bird could be extinct by the early 2030s. Forestry remains identified as the greatest threat, though government officials have historically downplayed the link.The Bob Brown Foundation accused both state and federal governments of “blatantly ignoring scientific advice” and allowing logging that drives the species toward extinction. A Tasmanian government spokesperson countered that the state’s “science‑based forest practices system” prohibits deforestation of swift‑parrot habitat, emphasizing that regenerated forests will provide future flowering eucalypts.At the federal level, a spokesperson for the Albanese government noted that a regional forestry agreement places responsibility for habitat protection on Tasmania, but an exemption for state‑run forestry from national environmental law expires in 2027. After that date, any logging that significantly impacts threatened species would require approval from Canberra.Environmental campaigners, including the Wilderness Society, have intensified pressure on retailers such as Bunnings to stop sourcing timber from the contested coupe. The society argues that the forest‑certification program awarded to logs from WT003E does not guarantee sustainable practices. Alice Hardinge, the Wilderness Society’s Tasmanian campaigns manager, warned that “customers don’t want to be sold timber that destroys unique forests and pushes the swift parrot to extinction.”Bunnings responded that an internal review found “no evidence to indicate non‑compliance with Tasmanian environmental or logging laws at this site,” reaffirming its commitment to sourcing wood from compliant, well‑managed operations.

The deployment of reflective mirrors on satellites and the launch of thousands more satellites into low Earth orbit could have significant consequences for human health and ecosystems. Leading sleep and circadian rhythm researchers have raised concerns about the potential disruption to natural night-time light environments.The US Federal Communications Commission (FCC) is considering plans by Reflect Orbital to illuminate parts of the Earth at night using reflective satellites, as well as applications from SpaceX that could dramatically expand satellite numbers in low Earth orbit.2,500 researchers from over 30 countries have expressed concerns that altering the light-dark cycle could disrupt biological clocks that regulate sleep and hormone secretion in humans and animals, migration in nocturnal species, seasonal cycles in plants, and the rhythms of marine phytoplankton.Prof Charalambos Kyriacou, president of the European Biological Rhythms Society (EBRS), emphasized that "plants need the night" and that eliminating it could have global implications for food security.Reflect Orbital aims to use satellites equipped with large reflective mirrors to redirect sunlight onto areas roughly 5km to 6km wide "on demand", with brightness adjustable "from full moon to full noon".Meanwhile, SpaceX has proposed launching up to 1m satellites to create a giant solar-powered computing network in orbit designed to run artificial-intelligence workloads.Ruskin Hartley, chief executive of DarkSky International, noted that scientific studies have already shown that the existing number of satellites in orbit has increased diffuse night sky brightness by roughly 10%.Experts warn that if current trends in satellite launches and debris generation continue, night sky brightness could increase substantially over the coming decade, approaching the threshold astronomers have set for preserving naturally dark skies.

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.”

Science is often seen as a dry and serious field, but does it have to be? A recent study published in Proceedings of the Royal Society B found that scientists deliver an average of only 1.6 jokes per presentation, with 66% generating only polite chuckles.The findings confirm previous research, including a randomized clinical trial conducted over 20 years ago by Timandra Harkness and Helen Pilcher under the guise of the Comedy Research Project. The study found that laughter levels failed to reach statistical significance, even when scientists attempted to incorporate humor into their talks.However, research suggests that humor can be an effective tool in science communication. A 2025 study called Wit Meets Wisdom found that humor can boost credibility and likability, making researchers seem more trustworthy and their findings less likely to be disputed.Helen Pilcher, a science writer and author, argues that scientists should not be afraid to adopt a more playful tone when communicating their research. By incorporating humor, scientists can build cohesion and foster a sense of shared perspective with their audience.Pilcher suggests that scientists can use humor to make their research more engaging and memorable, without having to convert it into standup comedy. By doing so, scientists can make their research more accessible and enjoyable for a wider audience.
