Adults with attention-deficit/hyperactivity disorder (ADHD) are nearly three times more likely to develop dementia than adults without ADHD, according to a new study. The study followed more than 100,000 older adults in Israel over 17 years to examine …

Using lake sediment cores, scientists determined how these subalpine ecosystems recovered after 4,800 years of fire.

Researchers are now presenting a new and efficient way to recycle metals from spent electric car batteries. The method allows recovery of 100 per cent of the aluminum and 98 per cent of the lithium in electric car batteries. At the same time, the loss …

In certain cases, a new method can provide as much information from brain images taken with computed tomography (CT) as images captured with magnetic resonance imaging (MRI). The method could enhance diagnostic support, particularly in primary care, fo…

Scientists  examining the evolutionary roots of language say they’ve discovered chimp vocal development is not far off from humans.

Researchers say mapping the genetic code of the brushtail possum will benefit those working to both conserve and control the animal.

The DNA double helix is composed of two DNA molecules whose sequences are complementary to each other. The stability of the duplex can be fine-tuned in the lab by controlling the amount and location of imperfect complementary sequences. Fluorescent mar…

A team has studied the mountainous star coral, Orbicella faveolata, to determine whether coral populations that have survived higher temperatures can pass their heat tolerance on to their offspring.  To the scientists’ surprise, the results showed the …

Now is the time to identify the conditions that cause plants to die. Doing so will allow us to better protect plants by choosing conservation targets more strategically, botanists argue.

A new study has revealed a significant association between eating disorders and physical multimorbidity, shedding new light on the health risks faced by people with these conditions. The research explores the complex relationship between eating disorde…

Researchers have shown female sex hormones play a significant role in how Alzheimer’s manifests in the brain. The study also highlights the importance of developing therapeutic strategies focused on these hormonal connections. The research indicates a …

Using cryo-electron microscopy (cryo-EM), researchers captured unprecedented images of key immune system receptors interacting with messenger proteins, elucidating how the receptors change shape upon activation and transmit signals within the cell. The…

Scientists measured microplastic concentrations in the highly productive Barents Sea and suggest that ocean circulation, ice melt, tourism, inadequate waste management, shipping and fishing are all likely contributors.

Infections with cytomegalovirus (CMV) are extremely common and often pose no major threat to the vast majority of people. They can however be deadly for people whose immune system is weakened, e.g., after bone marrow transplantation. Current treatments…

Depression and anxiety among college students is a growing public health problem. And new research suggests the problem may be worse for students who aren’t the same race as most of their peers. The new study found that students who were not the majori…

Researchers took a closer look at what would happen to agriculture if there was an extra cost, or so-called social cost, added to fossil fuels, which are essential for making fertilizer used in farming. They found that while CO2 emissions would decline…

Scientists have announced the results of an unprecedented collaboration to search for the source of the largest ever seismic event recorded on Mars. The study rules out a meteorite impact, suggesting instead that the quake was the result of enormous te…

The world may have crossed a ‘tipping point’ that will inevitably make solar power our main source of energy, new research suggests.

As Halloween approaches, so too does the anticipation of a trick-or-treating stash filled with fun-sized chocolate candy bars. But to satisfy our collective craving for this indulgence, millions of cocoa pods are harvested annually. While the beans and…

Schizophrenia, a neurodevelopmental disorder that features psychosis among its symptoms, is thought to arise from disorganization in brain connectivity and functional integration. Now, a new study finds differences in functional brain connectivity in p…
