Having coronary heart disease at a younger age was associated with an increased risk of dementia, Alzheimer’s disease and vascular dementia, finds a new study.

Around 400,000 years ago, early humans hunted beavers as a food resource and possibly also for their pelts.The authors show that Middle Pleistocene humans systematically fed on these smaller animals and hence had a more varied diet than thus far known….

People with personality traits such as conscientiousness, extraversion and positive affect are less likely to be diagnosed with dementia than those with neuroticism and negative affect, according to a new analysis. The difference was not linked to phys…

Researchers have discovered antibodies that interact with pancreatic cancer cells and healthy cells. These findings contribute to our knowledge of how the disease works. And they could help pinpoint future efforts for developing immunotherapy strategies.

Researchers discover a new type of ultrafast magnetic switching by investigating fluctuations that normally tend to interfere with experiments as noise.

While life on Earth is relatively new, geologically speaking, the ingredients that combined to form it might be much older than once thought. The simplest amino acid, carbamic acid, could have formed alongside stars or planets within interstellar ices….

New research has provided a detailed examination of England’s bottlenose dolphin population’s existence and the challenges it faces from human activities and environmental factors on a daily basis.

Blood tests are a common, yet often painful, step in health care. But what if we could skip the needles altogether? Saliva and blood contain many of the same biomarkers, and collecting spit is as simple as drooling into a container. Researchers have de…

Bees, wasps and ants belong to the Hymenoptera order and inject a whole cocktail of venomous ingredients when they sting. Despite their tremendous ecological and economic importance, little was previously known about the origins of their venom. Through…

Perceptions about sustainability and healthy food choices are closely linked, a new study shows.

Scientists have developed an injectable or catheter-administered hydrogel with enhanced capabilities for treating hepatocellular carcinoma, a deadly form of liver cancer. This drug-eluting hydrogel can provide sustained, pH-dependent drug co-delivery a…

Researchers have been working to better understand what drives melanoma brain metastasis. They now report on the identification of a cell signaling pathway that regulates the metastatic spread of melanoma cells to the brain.

Used lithium-ion batteries from cell phones, laptops and a growing number of electric vehicles are piling up, but options for recycling them remain limited mostly to burning or chemically dissolving shredded batteries. Researchers have improved on appr…

Cutting-edge computer simulations combined with theoretical calculations are helping astronomers better understand the origin of some of the universe’s most energetic and mysterious light shows — gamma-ray bursts, or GRBs. The new unified model confir…

In a new study using brain scans of former NFL athletes, researchers say they found high levels of a repair protein present long after a traumatic brain injury such as a concussion takes place.

A novel pilot study incorporating mindfulness into exposure therapy shows promise for reducing symptoms of post-traumatic stress in cardiac arrest survivors. One in three survivors of cardiac arrest survivors develop PTSD,  increasing their risk of mor…

The largest review of papers for brain cancer that has spread from the lungs has found abnormalities in the brain cancer and for which licensed drugs could be clinically trialed to find out if they could treat the disease.  The research also found gene…

Cryptocurrency mining uses a significant amount of water amid the global water crisis, and its water demand may grow further. Researchers provides the first comprehensive estimate of Bitcoin’s water use. He warns that its sheer scale could impact drink…

A landmark study into the geological timescale distribution of sediment and nutrients over 500 million years shows that species biodiversity on Earth is driven by landscape dynamics.

Scientists have developed a new tool for the measurement of entanglement in many-body systems and demonstrated it in experiments. The method enables the study of previously inaccessible physical phenomena and could contribute to a better understanding …
