Love summer but hate winter? Here's why your mood shifts so much with the seasons

Wavefront shaping is a promising approach to deep tissue imaging. Until now, it was possible only via an invasive approach: fluorescent points were manually inserted into the sample, and the tissue was indirectly mapped by imaging them. That process has many disadvantages, and it was clear that direct imaging of the tissue is a better way.

Senescent cells, which are damaged and inflammatory, contribute significantly to aging. Researchers at the Max Planck Institute for Biology of Aging have found that worms can enter a senescent-like state, similar to that observed in mammals. This discovery provides a simple yet powerful model to study senescence at the whole organism level, enabling the identification of new ways to prevent or reverse senescence. Published in Nature Aging, these findings hold promise for developing therapies targeting age-related conditions and cancer dormancy.

When Novak Djokovic limped out of the 2024 French Open with a torn meniscus in his knee, all eyes turned to whether he'd be fit for Wimbledon. And when Nick Kyrgios pulled out of Wimbledon for the third year running earlier this month due to a knee injury, fans were disappointed, but medical experts may not have been surprised.

An engineered protein turns off the kind of immune cells most likely to damage tissue as part of type-1 diabetes, hepatitis, multiple sclerosis, shows a new study in mice.

"He hides his smile in every school photo," Jayden's mother told me, holding up a picture of her 6-year-old son.

Because aging weakens cognitive skills, older people can struggle to read difficult social cues. A brain region involved in attention and arousal—the locus coeruleus (LC)—helps with complex tasks, and its connections to the cortex may adapt as humans age to support cognition.

How does the human brain track emotions and support transitions between these emotions? In a new eNeuro paper, Matthew Sachs and colleagues, from Columbia University, used music and an advanced approach for assessing brain activity to shed light on the context dependence and fluctuating nature of emotions.

In a world flooded with fitness fads and "quick-fix" workout plans, solid evidence can often get drowned out. Yet the science is clear: jogging for just five to ten minutes a day can lower your risk of dying from heart disease and even reduce your overall risk of dying from any cause. This kind of research rarely gets the attention it deserves.

Many of us have gotten into the habit of listening to podcasts, audiobooks and other online content at increased playback speeds. For younger people, it might even be the norm. One survey of students in California, for instance, showed that 89% changed the playback speed of online lectures, while there have been numerous articles in the media about how common speedy viewing has become.

A recent study of outcomes in infants and young deaf children with cochlear implants (implanted electronic hearing device), suggests that socioeconomic status (SES) plays a major role in whether spoken language becomes their primary communication mode. The researchers found that communication primarily using spoken language occurred in 85% of commercially insured children with cochlear implants compared to 33% of Medicaid-eligible children. Results were published in the journal Laryngoscope.

A drug used for Parkinson's disease has been shown to be effective in reducing the symptoms of difficult to treat depression, according to a study led by the University of Oxford.

Nestle has joined a growing list of major food companies pledging to voluntarily eliminate artificial colors from their U.S. products by the middle of next year amid mounting health concerns.

If you've started running for the first time, started again after a break, or your workout is more intense, you might have felt it. A dull, nagging ache down your shins after you exercise.

Why is it so hard to stop at just one cookie? For many people, sweet foods like chocolate, pastries, and candy aren't just a treat—they're a source of craving, guilt and emotional struggle. A newly published pilot study introduces the FitMIND Foundation Sweets Addiction Scale (FFSAS)—the first validated tool developed specifically to measure addiction-like behaviors related to sweets.

Millions of adults around the world are diagnosed with ADHD every year, and there is a great need for research in the field. However, much clinical research on adult ADHD suffers from serious methodological shortcomings that make it difficult to use the results in practice, researchers from the University of Copenhagen and the University of Sao Paulo show in a new study.

U.K. adults with psoriasis may be compromising their health and risking exacerbating their skin condition by seeking unverified dietary advice on social media, Herts researchers have warned.

A study from Texas A&M University reveals that hospital rooms designed with natural elements—like indoor plants, green decor and views of green nature—significantly enhance relaxation and mental clarity in simulated patients, even when experienced through virtual reality (VR).

Researchers from Monash University, in collaboration with the European Biostasis Foundation and Apex Neuroscience, have revealed that although most neuroscientists agree that long-term memories depend primarily on neuronal connectivity patterns, significant uncertainties persist regarding precisely how these memories are structurally encoded.
