We humans are fixated on big brains as a proxy for smarts. But headless animals called brittle stars have no brains at all and still manage to learn through experience, new research reveals. These shy marine creatures have no brain to speak of -- just nerve cords running down each of their five wiggly arms. But that seems to be enough to learn by association, researchers report.   Read more ›

With little insight into the impact of a lack of sleep on risky decision-making at the neuroimaging level, researchers found a 24-hour period of sleep deprivation significantly impacted individuals' decision-making processes by dampening neural responses to the outcomes of their choices.

For many people with migraine, it can be difficult to find a treatment that is effective and reliable, and information on how medications compare to one another is lacking. A new study draws data from nearly 300,000 people using a smartphone app to help people make decisions about their medications. The study found that certain migraine medications like triptans, ergots and anti-emetics may be two to five times more effective... Read more ›

The record storm surge in October 2023 caused severe damage to the German Baltic coast. Effective adaptation scenarios to rising sea levels are therefore becoming increasingly urgent. In two recent studies, researchers have modeled both the flooding extent along the Baltic Sea coastal areas and two possible upgrades for current dike lines in high resolution. They modeled various storm surge and sea level rise scenarios. Read more ›

Using artificial intelligence (AI) to analyze specialized brain MRI scans of adolescents with and without attention-deficit/hyperactivity disorder (ADHD), researchers found significant differences in nine brain white matter tracts in individuals with ADHD. Read more ›

The ARIES-HM3 Randomized Clinical Trial assessed the safety and efficacy of excluding aspirin from the antithrombotic regimen in patients with advanced heart failure who have undergone implantation of a fully magnetically levitated left ventricular assist device (LVAD). The clinical trial found that excluding aspirin from the antithrombotic regimen in patients with a levitated left ventricular assist device was safe. Read more ›

The San Joaquin Valley in California has experienced vast variability in climate extremes, with droughts and floods that were more severe and lasted longer than what has been seen in the modern record, according to a new study of 600 years of tree rings from the valley. Read more ›

When entering public restrooms, it's hard not to dwell on what germs previous users have left behind in the toilet bowl. Imagine, instead, a self-cleaning system that doesn't require a brightly colored gel. Researchers have developed a simple, transparent coating that makes surfaces, like porcelain, more water-repellent. They show how this surface treatment effectively prevents bacteria from sticking to the inside of a toilet bowl. Read more ›

World War II concluded decades ago, but live mines lurking on the ocean floor still pose threats, potentially spewing unexpected geysers or releasing contaminants into the water. Experts conduct controlled explosions to clear underwater munitions, but concerns have arisen over the environmental impacts from these blasts. New results show that the contamination produced by detonation depends on the blast type, with weaker explosions leaving behind more potentially toxic residues. Read more ›

Researchers have uncovered a mechanism that safeguards the biallelic expression of haploinsufficient genes, shedding light on the importance of having two copies of each chromosome. A study identified the epigenetic regulator MSL2 an 'anti-monoallelic' factor that maintains biallelic gene dosage. This discovery not only reveals a communication system between parental alleles but also points to potential therapeutic strategies for diseases associated with haploinsufficient genes. Read more ›

Astronomers have found a key new system of six transiting planets orbiting a bright star in a harmonic rhythm. This rare property enabled the team to determine the planetary orbits which initially appeared as an unsolvable riddle. Read more ›

The Second Plague Pandemic of the mid-14th century, also known as the Black Death, killed 30-60 percent of the European population and profoundly changed the course of European history. New research suggests that this plague, potentially through resulting changes in diet and hygiene, may also be associated with a shift in the composition of the human oral microbiome toward one that contributes to chronic diseases in modern-day humans.  Read more ›

A new study has confirmed that pesticides, commonly used in farmland, significantly harm bumblebees one of the most important wild pollinators. In a huge study spanning 106 sites across eight European countries, researchers have shown that despite tightened pesticide regulations, far more needs to be done. Read more ›

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 physical damage to brain tissue found in dementia patients, but more likely to how certain personality traits help people navigate dementia-related impairments.
