Ancient DNA used to map evolution of fever-causing bacteria
2025-05-22
Researchers at the Francis Crick Institute and UCL have analysed ancient DNA from Borrelia recurrentis, a type of bacteria that causes relapsing fever, pinpointing when it evolved to spread through lice rather than ticks, and how it gained and lost genes in the process.
This transition may have coincided with changes in human lifestyles, like living closer together and the beginning of the wool trade.
Borrelia recurrentis bacteria cause relapsing fever, an illness with many recurring episodes of fever, which is typically found ...

New standards in nuclear physics
An international research team led by the Paul Scherrer Institute PSI has measured the radius of the nucleus of muonic helium-3 with unprecedented precision. The results are an important stress test for theories and future experiments in atomic physics.
1.97007 femtometre (quadrillionths of a metre): That’s how unimaginably tiny the radius of the atomic nucleus of helium-3 is. This is the result of an experiment at PSI that has now been published in the journal Science. More than 40 researchers from international institutes collaborated to develop and implement a method that ...
Why Europe’s fisheries management needs a rethink
2025-05-22
As legally required by the European Union, sustainable fisheries may not extract more fish than can regrow each year. Yet, about 70 per cent of commercially targeted fish stocks in northern EU waters are either overfished, have shrunken population sizes or have collapsed entirely. So why does the EU continue to miss its sustainable fisheries targets, despite a wealth of scientific data and policy instruments? Researchers at GEOMAR Helmholtz Centre for Ocean Research Kiel and Kiel University examined this question using the well-explored ...

New factor linked to heart failure
2025-05-22
When the workload on the heart increases, the ventricular wall may thicken too, known as cardiac hypertrophy. This is an adaptive response that reduces pressure on the heart and maintains the activity of this vital organ. It is often a reversible process that does not cause serious effects on the structure or function of the heart, but if the factor causing cardiac overload becomes chronic, it can lead to pathological hypertrophy with more serious effects (dilatation of the ventricular cavities, alterations in cardiac function, heart failure, etc.).
People with diabetes — specially type 2 diabetes (DM2) — are at increased risk ...

New golden standard for medicine safety during breastfeeding
2025-05-22
Women who choose to stop treatment during pregnancy and breastfeeding are putting their health at risk, and have to weigh their desire to have children and breastfeed against a risk that we know very little about. In two ongoing clinical trials, researchers establish a new standard for human lactation studies that includes sampling of breast milk and plasma from both mothers and breastfed infants.
“The lack of scientific evidence is an ethical problem for women and doctors, considering that around 70 percent of women need to use medicines sometime during their pregnancy. In many cases, women are recommended ...
Infrared contact lenses allow people to see in the dark, even with their eyes closed
2025-05-22
Neuroscientists and materials scientists have created contact lenses that enable infrared vision in both humans and mice by converting infrared light into visible light. Unlike infrared night vision goggles, the contact lenses, described in the Cell Press journal Cell on May 22, do not require a power source—and they enable the wearer to perceive multiple infrared wavelengths. Because they’re transparent, users can see both infrared and visible light simultaneously, though infrared vision ...
Climate change: Penguin guano may help reduce effects of climate change in Antarctica
2025-05-22
Ammonia released from penguin guano may help to reduce the effects of climate change in the Antarctic by contributing to increased cloud formation, according to an analysis published in Communications Earth & Environment. The conclusion is the result of measurements taken downwind of a colony of Adelie penguins (Pygoscelis adeliae).
Antarctic ecosystems are facing significant pressures because of human-driven climate change, including a recent decreasing trend in the area covered by sea ice. Penguins are key species in the Antarctic ecosystem whose habitat is threatened by this ongoing ice loss. They are also, along with other ...
New study reveals impact of neighborhood disadvantage on menopause onset
2025-05-22
Key Findings
Women living in neighborhoods with high vulnerability had a higher risk of earlier natural menopause onset, primarily due to socioeconomic status and household conditions.
No significant association was found between neighborhood disadvantage and the severity of menopause symptoms.
Boston, MA – A new study led by the Harvard Pilgrim Health Care Institute highlights the significant impact of living in disadvantaged neighborhoods on the onset of menopause. The research followed 691 women from pregnancy to midlife and found that those residing in highly vulnerable neighborhoods, particularly within 10 years of perimenopause onset, experienced menopause approximately two ...
Cardiac events in adults hospitalized for RSV vs COVID-19 or influenza
2025-05-22
About The Study: In this cross-sectional study, 1 in 10 patients hospitalized for respiratory syncytial virus (RSV) had a concurrent acute cardiovascular event. Odds of cardiac events were significantly higher in RSV vs COVID-19 hospitalizations in both vaccine-boosted and unboosted individuals. In contemporaneous hospitalizations for RSV or influenza after the pandemic (2023-2024), odds of heart failure were significantly higher in RSV hospitalizations vs vaccine-breakthrough influenza hospitalizations. These findings suggest that patients with preexisting cardiovascular risk should consider vaccination ...

Early childhood weight patterns may signal future obesity risk, NIH study finds
2025-05-22
Not all children grow the same way. A new study from the Environmental influences on Child Health Outcomes (ECHO) Program suggests that body weight changes in early childhood may be associated with later obesity risk.
Funded by the National Institutes of Health (NIH), the study tracked children’s body mass index (BMI) from infancy through age 9 and found two distinct growth patterns. Most children followed a typical curve, with BMI decreasing in early childhood before gradually rising again. But a smaller group followed a trajectory marked by a sharp rise in BMI, ...
Motorcycle helmet laws save lives: Study shows universal laws increase helmet use and reduce injury severity
2025-05-22
Key Takeaways
Helmet laws work (when they’re universal): Motorcycle riders in North Carolina (with a universal helmet law) wore a helmet 94% of the time compared with 47% of riders in South Carolina (partial law).
Helmets mean less severe injuries: Motorcyclists who wore helmets were less likely to die or require intensive care after an accident.
Lost progress: Helmet laws have been rolled back in many states resulting in only 19 states now having universal helmet laws.
