New research has uncovered that anxiety and apathy — two common but distinct emotional states — lead to fundamentally different patterns in how people learn and make decisions.

Hydrogen energy is widely recognized as a sustainable source for the future, but its large-scale production still relies on expensive and scarce platinum-based catalysts. In order to address this challenge, researchers have developed Bis(diimino)palladium coordination nanosheets (PdDI), a novel two-dimensional electrocatalyst that effectively facilitates the hydrogen evolution reactions while minimizing the use of precious metals like platinum, paving the way for affordable hydrogen production.

A study of Asian hornets has found about 1,400 different species in their guts.

Everyday smartwatches are extremely accurate in detecting viral infection long before symptoms appear — now, research shows how they could help stop a pandemic before it even begins.

Results from a phase 1/2 clinical trial of a novel stem cell treatment for cornea injuries found 14 patients treated and tracked for 18 months had a more than 90% success rate at restoring the cornea’s surface and improvements in vision. The procedure, called CALEC (cultivated autologous limbal epithelial cells) involves taking stem cells from a healthy eye, expanding it into a graft over several weeks, then transplanting it into a patient’s damaged eye. The groundbreaking procedure was developed to help people with injuries like chemical burns that lead to irreversible limbal stem cell deficiency, and the researchers hope the new findings warrant additional trials.

Researchers explore the likelihood that Earth’s climate, as affected by solar heat, plays a role in seismic activity. Using mathematical and computational methods, they analyzed earthquake data alongside solar activity records and surface temperatures on Earth and observed that when they included Earth surface temperatures into their model, the forecasting became more accurate, especially for shallow earthquakes.

Having one traumatic experience is bad enough. If you’ve constantly experienced stress since before birth, you may be in for an especially tough time. Our emotions may be influenced by infections experienced in the mother’s womb. This can result from two-hit stress, where an infection during pregnancy is followed by social stress during postpartum development. A team of researchers recently set out to understand the mechanisms behind which two-hit stress contributes to brain dysfunction and mental disorders.

Hundreds of thousands die each year with millions more suffering due to lack of access to medical oxygen.

Obesity rates are set to skyrocket, with one in six children and adolescents worldwide forecast to be obese by 2050, according to a new study. But with significant increases predicted within the next five years, the researchers stress urgent action now could turn the tide on the public health crisis.

Melting ice sheets are slowing the Antarctic Circumpolar Current (ACC), the world’s strongest ocean current, researchers have found. This melting has implications for global climate indicators, including sea level rise, ocean warming and viability of marine ecosystems. The researchers have shown the current slowing by around 20 per cent by 2050 in a high carbon emissions scenario.
