A drug used to treat agitation in people with dementia is no more effective than a placebo, and might even increase mortality, according to a new study. The research has shown that antidepressant mirtazapine offered no improvement in agitation for peop…

The skin bacterium Staphylococcus aureus often develops antibiotic resistance. It can then cause infections that are difficult to treat. Researchers have now uncovered an ingenious way in which a certain strain of Staphylococcus aureus protects itself …

Want to ensure your child hits their expected developmental milestones? New research suggests living in areas with high exposure to green-space can help set them up for success.

Collagen, the main component of the skin’s extracellular matrix, can cause a pathological condition if it is in excess. Applying an electric field to the skin affects collagen pathways, temporarily reducing collagen production and increasing its degrad…

Lakes in the Northern Hemisphere are warming six times faster since 1992 than any other time period in the last 100 years, new research has found.

New findings add to a growing body of evidence indicating that type 1 diabetes is not a single disease. The presentation and, perhaps, cause of autoimmune diabetes differs among genetically high-risk children, the University of South Florida Health-led…

Fossil footprints found in an Australian coal mine around 50 years ago have long been thought to be that of a large ‘raptor-like’ predatory dinosaur, but scientists have in fact discovered they were instead left by a timid long-necked herbivore.

The first-ever Africa-wide assessment of great apes — gorillas, bonobos and chimpanzees — finds that human factors, including roads, population density and GDP, determine abundance more than ecological factors such as forest cover.

With age, the human heart gradually loses its ability to repair itself following injury. Damage wrought by injuries such as cardiac ischemia and heart attack, which are associated with decreased oxygen levels in the heart, can cause the heart to functi…

Researchers have used high-density nanofibers that mimic the microenvironment of the brain to capture tumor cells, opening doors to novel therapeutic solutions for aggressive brain cancer.

Scientists have created wearable, stitchable, and sensitive sensors from flexible polymers and bundles of carbon fibre. Like our skin, these sensors respond to pressure and can measure body position and movement. They could be used to measure disease p…

Tap water produces a natural protective shield against harmful microplastics, which can help prevent household products such as plastic kettles from releasing them.

Scientists believe they have found the earliest evidence for complex herd behavior in dinosaurs. Researchers say Mussaurus patagonicus may have lived in herds some 193 million years ago — 40 million years earlier than other records of dinosaur herding.

Scientists have taken a holistic approach to find that concrete alone doesn’t make urban water ecosystem services sustainable.

Researchers have developed ‘mini brains’ that allow them to study a fatal and untreatable neurological disorder causing paralysis and dementia — and for the first time have been able to grow these for almost a year.

What if we could identify proteins as easily as we can sequence DNA and RNA? Perhaps soon we will, thanks to new DNA Nanoswitch Calipers. DNA Calipers create a unique ‘fingerprint’ for peptides (the building blocks of proteins) by repeatedly applying f…

A team has updated its asteroid bombardment model of the Earth with the latest geologic evidence of ancient, large collisions. These models have been used to understand how impacts may have affected oxygen levels in the Earth’s atmosphere in the Archea…
