The global loss of wildlife is “significantly more alarming” than previously thought, according to a new study that found almost half the planet’s species are experiencing rapid population declines. Humans have already wiped out huge numbers of species and pushed many more to the brink – with some scientists saying we are entering a “sixth mass ... Read More »
Scientists have used a “surprising” new animal model – the African killifish – to show that muscles reverse to an “early-life” state towards the end of life, an advance which may lead to reversing age-related strength loss in humans. While previous research has shown that muscles start to waste in old age ... Read More »
A rare genetic resilience to Alzheimer’s disease has been identified in a second patient, a new study suggests. Researchers have found a patient with a genetic predisposition for developing early-onset Alzheimer’s who remained cognitively intact until his late 60s. According to the study, a series of tests and analyses revealed ... Read More »
Advanced artificial intelligence could pose a catastrophic risk to humanity and wipe out entire civilisations, a new study warns. AI could be the potential “Great Filter” answer to the Fermi paradox, with the potential to wipe out intelligent life in the universe before it can make contact with others, suggested the yet-to-be peer-reviewed study, posted ...

Simple tests assessing grip strength and mobility can predict people’s risk of ageing-related health conditions such as dementia, according to a new study. Previous studies have shown that as people age, they generally tend to lose muscle strength and slow down. The new research, published recently in the Journal of Cachexia Sarcopenia and Muscle, suggests this could also ... Read More »
Scientists have found a planetary system with a “forbidden” world, which could rewrite the story of how such planets form. The planet has a large, gas giant planet, similar to our Jupiter. But its star is a red dwarf, just four times the size of Jupiter itself. Scientists previously thought that it ... Read More »
A recent study found that heart attacks in people ages 25 to 44 increased by 30% compared to the expected number over the first two years of the COVID-19 pandemic. When Demi Washington, a basketball player at Vanderbilt University came down with COVID-19 in late 2020, her symptoms were mild, ... Read More »
In rare good news for the planet, Earth’s ozone layer is on track to recover completely within decades, as ozone-depleting chemicals are phased out across the world, according to a new United Nations-backed assessment. The ozone layer protects the planet from harmful ultraviolet rays. But since the late 1980s, scientists have sounded the ... Read More »
Scientists have discovered a while new layer of tissues in the brain that acts as a protective barrier and also as a platform from which immune cells monitor the brain for infection and inflammation. The research, published in the journal Science on Thursday, assessed membranes that encase the brain and keep it bathed in CSF ... Read More »
An experimental Alzheimer’s drug modestly slowed the brain disease’s inevitable worsening, researchers reported — but it remains unclear how much difference that might make in people’s lives. Japanese drugmaker Eisai and its U.S. partner Biogen had announced earlier this fall that the drug lecanemab appeared to work, a badly needed bright spot after ... Read More »
