The world is getting brighter at night but some places are going dark

Satellite observations show that the planet is steadily getting brighter at night, but the trend is far from uniform. Data from the VIIRS DNB instrument, covering 2014 to 2022, indicate that global nighttime lighting has been increasing by roughly two percent each year. “Although there has been a total increase…

Scientists just found a hidden “drain” inside the human brain

How does the brain get rid of waste? It relies on a specialized drainage network known as the lymphatic system. Scientists have been working to understand how this system functions, and in the process, they have pushed brain imaging technology to new limits. A new study published in iScience by…

Dragonflies can see a color humans can’t and it could change medicine

Different species sometimes arrive at the same biological solution on their own, a phenomenon known as parallel evolution. Researchers at Osaka Metropolitan University (OMU) have now found that dragonflies detect red light in a way that closely mirrors how mammals, including humans, do. Because many medical technologies depend on red…

Il question time al Senato, Giorgetti: ‘Credo nei miracoli, in passato previsioni superate’ – Notizie – Ansa.it

“Premesso che io ai miracoli ci credo, vorrei sottolineare che il quadro” delineato dalle ultime ultime statistiche “non indica il deterioramento strutturale” dell’economia italiana e ha dimostrato una significativa resilienza allo shock del commercio internazionale”. Lo afferma il ministro dell’Economia, Giancarlo Giorgetti, rispondendo al question time al Senato. “Guardando al…

Your brain can trick you into liking artificial sweeteners

Researchers from Radboud University, the University of Oxford, and the University of Cambridge set out to test a surprising idea. Could simply changing what people expect to taste alter how much they enjoy sweet drinks? Their findings, published in JNeurosci, suggest the answer is yes. The team studied 99 healthy…

Brain study reveals hidden link between autism and ADHD

A study published in Molecular Psychiatry suggests that autism and ADHD may be connected at a biological level in ways that go beyond traditional diagnostic labels. While it is well known that the two conditions often occur together, the underlying mechanisms they may share have remained unclear. Researchers from the…

Scientists discover hidden gut trigger behind ALS and dementia

Researchers at Case Western Reserve University have uncovered a finding that could reshape how doctors approach two of the most devastating brain disorders. Their work points to an unexpected player in disease progression: gut bacteria. The team identified a clear connection between microbes in the digestive system and brain damage…

The hidden tradeoff behind today’s most popular weight loss drugs

New research from Vanderbilt Health shows that both modern weight loss drugs and bariatric (weight loss) surgery can improve body composition in people with obesity. These treatments lead to a large drop in fat while also causing a smaller reduction in fat-free mass (including lean muscle). This balance matters because…

Scientists discover spice synergy that boosts anti-inflammation 100x

Chronic inflammation often develops quietly, without obvious pain or noticeable symptoms. Over time, however, it can contribute to serious health problems such as type 2 diabetes, heart disease, obesity, arthritis, and even cancer. Inside the body, this process is driven by immune cells that release chemical signals to respond to…

Humans reached Australia 60,000 years ago, new DNA study reveals

A large international collaboration between researchers at the University of Huddersfield and the University of Southampton has provided new insight into when and how modern humans, Homo sapiens, first settled New Guinea and Australia. The project brought together experts in archaeogenetics and maritime archaeology, with funding from the European Research…

Breakthrough water filter removes 98% of toxic PFAS forever chemicals

Contamination from perfluoroalkyl and polyfluoroalkyl substances (PFAS) has spread into groundwater, surface water, and even drinking supplies, affecting millions of people around the world. Researchers at Flinders University have now developed a promising new approach that could help remove some of the hardest-to-capture forms of these long-lasting pollutants from water.…
