Debilitating tropical virus can spread in cool weather, posing a greater health risk than previously thought

Chikungunya virus, a debilitating tropical disease caused by infected mosquito bites, poses a greater health threat in Europe than previously thought because it can be spread when air temperatures are as low as 13°C. Researchers at the UK Center for Ecology & Hydrology investigated the ability of the Asian tiger mosquito to spread the virus, which is rarely fatal but can cause long-term chronic joint pain.

They drew up a map showing the extent of the risk of chikungunya for 10 km-square areas across Europe including the U.K. The risk map shows the threat of virus transmission may last several months of the year in warmer parts of the continent where the tiger mosquito is already established. The research is published in the Journal of the Royal Society Interface.

There were record numbers of local outbreaks of chikungunya in France and Italy in 2025, and the tiger mosquito has also been responsible for increasing numbers of cases of dengue fever in these countries in recent years. This mosquito species is only occasionally detected in south-east England and is not yet established, so the current risk of local transmission in the U.K. remains very low.

Ancient mind-body practice proven to lower blood pressure in clinical trial

A traditional Chinese mind-body practice that combines slow, structured movement, deep breathing and meditative focus lowered blood pressure as effectively as brisk walking in a large randomized clinical trial published in JACC. Blood pressure reductions were seen after three months and sustained for one year.

High blood pressure is one of the leading preventable risk factors for heart disease. Clinical guidelines recommend regular physical activity, yet long-term adherence to exercise programs is challenging for many people, particularly when routines require equipment, dedicated space, gym memberships or ongoing supervision.

Baduanjin is a widely practiced, standardized eight-movement sequence that integrates aerobic, isometric, flexibility and mind–body components. Practiced for centuries and commonly performed in community settings across China, the routine typically takes 10–15 minutes and requires no equipment and only minimal initial instruction, allowing it to be performed in a wide range of settings. Because it is low-to moderate-intensity, it is considered safe and accessible for many adults.

Chitosan-nickel biomaterial becomes stronger when wet, and could replace plastics

A new study led by the Institute for Bioengineering of Catalonia (IBEC) has unveiled the first biomaterial that is not only waterproof but actually becomes stronger in contact with water. The material is produced by the incorporation of nickel into the structure of chitosan, a chitinous polymer obtained from discarded shrimp shells. The development of this new biomaterial marks a departure from the plastic-age mindset of making materials that must isolate from their environment to perform well. Instead, it shows how sustainable materials can connect and leverage their environment, using their surrounding water to achieve mechanical performance that surpasses common plastics.

Plastics have become an integral part of modern society thanks to their durability and resistance to water. However, precisely these properties turn them into persistent disruptors of ecological cycles. As a result, unrecovered plastic is accumulating across ecosystems and becoming an increasingly ubiquitous component of global food chains, raising growing concerns about potential impacts on human health.

In an effort to address this challenge, the use of biomaterials as substitutes for conventional plastics has long been explored. However, their widespread adoption has been limited by a fundamental drawback: Most biological materials weaken when exposed to water. Traditionally, this vulnerability has forced engineers to rely on chemical modifications or protective coatings, thereby undermining the sustainability benefits of biomaterial-based solutions.

One Injection. Permanent GLP-1? The Future of Weight Loss & Metabolic Therapy

A company called Fractal Health is developing a one-time GLP-1 gene therapy and the first humans are being dosed this year.

Instead of weekly injections like semaglutide or tirzepatide, this approach delivers genes directly into pancreatic beta cells. The therapy is controlled by the insulin promoter, meaning GLP-1 is only released when you eat — not continuously.

That could mean fewer systemic side effects and a more physiologic response.

They’re developing two versions:
• GLP-1 alone.
• GLP-1 + GIP (similar to tirzepatide)

One injection. Potentially permanent metabolic support.

If this works, it could redefine obesity and diabetes treatment.

Standard mental health tests may be inaccurate for highly intelligent people

The researchers found that as intelligence scores rise, the questions on common mental health surveys lose their ability to consistently measure the underlying psychological condition. These results were published in the journal Intelligence.

The concept of the “tortured genius” is a cultural staple. It suggests that high intelligence is accompanied by social isolation, existential anxiety, or other psychological difficulties. Previous research on this topic has produced conflicting results. Many large-scale studies indicate that intelligence generally correlates with better health and happiness.

However, other researchers argue that this relationship might not be a simple straight line. They propose a “nonlinear” relationship. This means intelligence could be protective up to a certain point, but extremely high levels might eventually lead to negative outcomes. This phenomenon is sometimes called the “too-much-of-a-good-thing” effect.

Peripheral Neural Plasticity in Cochlear Implant Users Across the Lifespan

Model-based analysis of ECAPs in CochlearImplant users showed stronger auditory nerve responses and plasticity in younger recipients, highlighting the value of early implantation.

Question Can neural responses measured in cochlear implant users be standardized to monitor auditory nerve health and plasticity over time?

Findings In this cohort study analyzing more than 169 000 recordings from more than 10 000 cochlear implants in 7,416 patients, auditory nerve activity varied by cochlear location and age at implantation. Children implanted at younger ages showed stronger responses and clear evidence of plasticity, particularly in the first 5 years after activation; these changes were not observed in older users.

Meaning Model-based analysis of neural recordings provide a scalable method for tracking auditory nerve health across the lifespan and highlight the importance of early implantation for long-term outcomes.

Studies show 11 genetic variants affect gut microbiome

In two new studies on 28,000 individuals, researchers are able to show that genetic variants in 11 regions of the human genome have a clear influence on which bacteria are in the gut and what they do there. Only two genetic regions were previously known. Some of the new genetic variants can be linked to an increased risk of gluten intolerance, hemorrhoids and cardiovascular diseases.

The studies are published in the journal Nature Genetics.

The community of bacteria living in our gut, or gut microbiome, has become a hot research area in recent years because of its great significance for health and disease. However, the extent to which our genes determine which bacteria are present in the intestines has been unclear. Until now, it has only been possible to link a few genetic variants to the composition of the gut microbiome with certainty.

Early signs of Parkinson’s can be identified in the blood

A team led by researchers at Chalmers University of Technology, Sweden, has succeeded in identifying biomarkers for Parkinson’s disease in its earliest stages, before extensive brain damage has occurred. The biological processes leave measurable traces in the blood, but only for a limited period.

The discovery thus reveals a window of opportunity that could be crucial for future treatment, but also for early diagnosis via blood tests, which could begin to be tested in health care within five years.

Parkinson’s is an endemic disease with over 10 million people affected globally. As the world’s population grows older, this number is expected to more than double by 2050. At present, there is neither an effective cure nor an established screening method for detecting this chronic neurological disorder at an early stage before it has caused significant damage to the brain.

New clue to treating hypertension: Blocking a brain receptor may calm blood pressure signals

The human body is often described in parts—different limbs, systems, and organs—rather than something fully interconnected and whole. Yet many bodily processes interact in ways we may not always recognize. For example, researchers at the University of Missouri School of Medicine may have found a link between high blood pressure and an overactive nervous system.

The paper is published in the journal Cardiovascular Research.

High blood pressure, also called hypertension, is a common cardiovascular condition and a risk factor for multiple diseases and sudden health concerns like stroke or heart attack.
