Black carbon pollution from tourism and research activities in Antarctica is likely increasing snowmelt on the continent by an estimated 83 tonnes for each visitor, according to new research. Scientists have estimated that the black carbon produced by vessels, planes and diesel generators results in 23mm of additional snowmelt each summer in ... Read More »
It is widely accepted as one of life’s bleak but unavoidable facts: as we get older, our brains get slower. But now a study, based on data from more than 1 million people, suggests that mental processing speed remains almost constant until the age of 60. The analysis puts perceived ... Read More »

We may have a new planetary neighbor orbiting just four light-years away. Astronomers have detected evidence of a third planet orbiting Proxima Centauri, our sun’s nearest stellar neighbor, at 25 trillion miles (40.2 trillion kilometers) away. A light-year, the distance light travels in one year in a vacuum, is equivalent ... Read More »
When young stars coalesce out of a cloud of molecular hydrogen, a disk of leftover material called a protoplanetary disk surrounds them. This disk is where planets form, and astronomers are getting better at peering into those veiled environments and watching embryonic worlds take shape. But young stars aren’t the ... Read More »
Research shows that average time from first exposure to viral detection and early symptoms was 42 hours, significantly shorter than existing estimates A controversial study in which participants were willingly infected with Covid has shown that it typically takes two days for symptoms to start developing after exposure to the virus. ...

A scientist who reported the existence of a new Covid-19 variant that combines characteristics of Delta and Omicron has insisted his findings are accurate after experts dismissed them as the result of laboratory samples becoming contaminated. Dr Leonidos Kostrikis, a professor of biological sciences at the University of Cyprus, told the Cypriot channel Sigma TV that ... Read More »
A new study found that introducing peanut products to babies and infants, and gradually increasing exposure, led to greater tolerance for the common allergen. The peer-reviewed study, published in The Lancet, involved 146 peanut-allergic children aged between zero and three over two-and-a-half years. Of the group, 96 were given peanut ... Read More »
