For years, scientists have debated whether humans or the climate have caused the population of large mammals to decline dramatically over the past several thousand years. A new study from Aarhus University confirms that climate cannot be the explanation.

In a novel study, researchers introduced LoGoFunc, an advanced computational tool that predicts pathogenic gain- and loss-of-function variants across the genome. Unlike current methods that predominantly focus on loss of function, LoGoFunc distinguishe…

Increased sedentary time in childhood can raise cholesterol levels by two thirds as an adult, leading to heart problems and even premature death — but a new study has found light physical activity may completely reverse the risks and is far more effec…

Blue light from LED lamps and consumer electronics can mess with your sleep because it disrupts production of the natural sleep hormone melatonin. Tinted glasses or displays in night mode can mask, but don’t remove, a portion of the disruptive waveleng…

With the holiday season in full swing, gifts of all shapes and sizes are being shipped around the world. But all that packaging generates lots of waste, including cardboard boxes and plastic-based foam cushioning. Rather than discard those boxes, resea…

Researchers have identified a welding technique that can be used to join composite metal foam (CMF) components together without impairing the properties that make CMF desirable. CMFs hold promise for a wide array of applications because the pockets of …

Using cells from kidney biopsies, researchers report progress in the search for more accurate and easier-to-obtain markers to help predict, manage and assess treatment of acute kidney injury (AKI). Marked by serious inflammation, AKI can lead to sudden…

New research has identified key, naturally occurring biochemical components of a novel therapeutic food that is aimed at repairing malnourished children’s underdeveloped gut microbiomes. The study also has identified the important bacterial strains tha…

Brown dwarfs are objects that straddle the dividing line between stars and planets. They form like stars, growing dense enough to collapse under their own gravity, but they never become dense and hot enough to begin fusing hydrogen and turn into a star…

People who have very irregular sleep patterns may have a higher risk of dementia than those who have more regular sleep patterns, according to new research. The study does not prove that sleep irregularity causes dementia. It only shows an association.

People who are very sleepy during the day, despite a good night’s rest, may have a sleep disorder called idiopathic hypersomnia. New research has found this neurologic disorder may not be as rare as once thought.

Researchers have come one step closer to unlocking the potential of synthetic DNA, which could help scientists develop never-before-seen proteins in the lab.

Scientists studied two complement components that are important parts of the immune system and are linked to schizophrenia and autoimmune disorders. They studied the link between two protein concentrations — C3 and C4 — in over 68,000 newborn babies …

While screen time is generally known to affect sleep, new research suggests that interactive engagement, such as texting friends or playing video games, delays and reduces the time spent asleep to a greater extent than passive screen time, like watchin…

New research has now demonstrated that it takes much longer than previously believed, longer than a month, for the effects of alcohol consumption to leave the father’s sperm. Because of this, it’s crucial that couples planning on getting pregnant know …

Using questionnaires created to determine whether a particular earthquake is natural or induced by human activity, a panel of experts concluded that the November 2022 magnitude 5.2 Peace River earthquake sequence in Alberta, Canada was likely to be ind…

Body dissatisfaction at age 11 is linked to increased risk of depression by age 14, finds a new longitudinal study.
