A scientific breakthrough not only promises faster testing for antimicrobial resistance, but also an ethical solution to the controversial issue of using rodents in research. University of Exeter scientists have created the world’s first genetically engineered wax moths – a development which could both accelerate the fight against antimicrobial resistance (AMR) and significantly reduce the need for mice and rats in infection research. The study, published in Nature Lab Animal, outlines how Exeter researchers have developed powerful new genetic tools for the greater wax moth (Galleria Mellonella). This small insect is increasingly recognised as a cost-effective, ethically ...

New York, NY [February 9, 2026] — Medical artificial intelligence (AI) is often described as a way to make patient care safer by helping clinicians manage information. A new study by the Icahn School of Medicine at Mount Sinai and collaborators confronts a critical vulnerability: when a medical lie enters the system, can AI pass it on as if it were true? Analyzing more than a million prompts across nine leading language models, the researchers found that these systems can repeat false medical claims when they appear in realistic hospital notes or social-media health discussions. The findings, published in the February 9 online issue of The Lancet Digital Health ...

Study of over 540,000 people suggests people with obesity are 70% more likely to be hospitalised or die from an infectious disease; people with the most severe obesity face three times the risk. Applying these risk estimates to global data suggests obesity was linked to one in ten infection-related global deaths in 2023.However, authors highlight estimates of the global impact should be interpreted with caution. The proportion of infection-related deaths associated with obesity differed between countries, with roughly one in six deaths in the UK an done in four deaths in the US. Authors warn that given rising global ...

Just over one in 10 deaths from a wide range of infectious diseases can be attributed to obesity worldwide, finds a major new study led by a University College London (UCL) researcher. People with obesity face a 70% higher risk of hospitalisation or death from an infection than those of a healthy weight, according to the findings published in The Lancet. Obesity can increase the risk posed by many different infectious diseases, from flu and Covid-19 to stomach bugs and urinary tract infections, and the researchers found that the higher the BMI, the greater the risk. The study’s lead author, Professor Mika Kivimaki (UCL Faculty ...

The legalisation of cannabis and the start of retail sales of the drug in the US are linked to both a rise in its recreational use and concurrent use of tobacco, as well as a fall in sole tobacco use, finds an analysis of health behavioural data, published online in the journal Tobacco Control.   These patterns were evident in higher risk groups, such as those with poor mental health, as well as those with historically lower levels of recreational cannabis use, such as older people and those with higher levels of education, the findings indicate.   Concurrent use of tobacco and cannabis is associated with an increased risk of developing ...

Harbour porpoises “buzz” less when boats and ships and nearby – suggesting a drop in feeding and socialising, new research shows. Scientists used underwater microphones in a narrow strait called the Little Belt (Denmark) then mapped porpoise sounds against vessel traffic. Buzzes (short sounds used when porpoises feed and socialise) reduced by up to 45% during busiest vessel traffic periods. Harbour porpoises are small but have a rapid metabolism and eat almost constantly – so reduced activity could ...

When we think about heat travelling through a material, we typically picture diffusive transport, a process that transfers heat from high-temperature to low-temperature as particles and molecules bump into each other, losing kinetic energy in the process. But in some materials heat can travel in a different way, flowing like water in a pipeline that – at least in principle – can be forced to move in a direction of choice. This second regime is called hydrodynamic heat transport. Heat conduction is mediated by movement of phonons, which are collective excitations of atoms in solids, ...

The study, recently published in the journal Nature Communications, is leading to a new understanding of how immune cells can influence  adult neurogenesis, the process of creating new neurons in the brain. Neurons are the brain's fundamental information messengers, and the immune cells conduct surveillance and send messages to new neurons. The study’s corresponding author is Yu (Agnes) Luo, PhD, professor and vice ...

Methane is a powerful greenhouse gas with strong heat-trapping capabilities. Although there is less methane in the atmosphere than carbon dioxide, the foremost greenhouse gas, researchers attribute 30% of modern global warming to methane. Observations show that methane levels have increased over time, but the factors driving changes in the rate of accumulation remain unclear. Methane stays in the atmosphere for approximately 10 years before it is broken down, or removed. Researchers need to know how much methane is removed to gauge what percentage of emissions are accumulating in the atmosphere, but the methane removal process is difficult ...

A new study conducted at the Potsdam Institute for Climate Impact Research (PIK) shows that grassland-based grazing systems – currently covering a third of the Earth’s surface and representing the world’s largest production system – will see a severe contraction as global temperatures rise. Depending on the scenario analysed, 36-50 percent of the land with suitable climatic conditions for grazing today will experience a loss of viability by 2100, affecting more than 100 million pastoralists and up to 1.6 billion grazing animals. The study, published in the scientific journal PNAS today, identifies a ‘safe climatic space’ for cattle, sheep and goat grazing. ...

UNIVERSITY PARK, Pa. —  Amino acids, the building blocks necessary for life, were previously found in samples of 4.6-billion-year-old rocks from an asteroid called Bennu, delivered to Earth in 2023 by NASA’s OSIRIS-REx mission. How those amino acids — the molecules that create proteins and peptides in DNA — formed in space was a mystery, but new research led by Penn State scientists shows they could have originated in an icy-cold, radioactive environment at the dawn of Earth’s solar system. According to the researchers, who published new findings today ...

Chimeric antigen receptor (CAR) T cell therapy, a type of immunotherapy that leverages the immune system to combat diseases, is a powerful treatment option for certain cancers. The treatment relies on genetically modified T cells — a type of immune cell — to destroy cancer cells. Now, researchers at Washington University School of Medicine in St. Louis and the Weizmann Institute of Science (WIS) in Israel and their collaborators have applied a similar approach to treating neurodegeneration. They engineered CAR-T ...

Toronto, February 9, 2026 – New research is proving persistent gender gaps in science, technology, engineering and mathematics (STEM) careers can’t be explained by academic ability alone. A recent Baycrest study suggests that success in STEM careers is shaped by different cognitive strengths and that these strengths relate differently to career outcomes for women and men. The findings offer new insight into why women remain underrepresented in computational STEM fields, such as computer science and engineering, despite comparable academic ability. The ...

GAINESVILLE, Fla. — Beginning in the late 1990s, nearly 3,000 older adults received brain training as part of a study to evaluate the training's effect on thinking and memory. Twenty years later, participants continued to reap the benefits.
