In a pioneering new study, researchers made the skin on the skulls and abdomens of live mice transparent by applying to the areas a mixture of water and a common yellow food coloring called tartrazine.
For many animals sleep is a social activity, but it’s usually studied as an individual process
Group sleeping can impact when animals sleep, how long they sleep for, and how deeply they sleep. For example, groups of meerkats time their sleep according to 'sleep traditions'; olive baboons sleep less when their group size increases; bumblebees suppress sleep in the presence of offspring; and co-sleeping mice can...
Travel could be the best defense against aging
Forget about retinol night creams, researchers believe travel could be the best way to defy premature aging. An interdisciplinary study has applied the theory of entropy to tourism, finding that travel could have positive health benefits, including slowing down the signs of aging.
Agriculture accelerated human genome evolution to capture energy from starchy foods
Scientists have suspected that modern humans have more genes to digest starch than our hunter-gatherer ancestors, but the amylase locus of the genome is hard to study. Researchers have now developed new methods to isolate the multiple amylase genes and compare the locus to ancient genomes. They found that amylase...
How Earth’s most intense heat wave ever impacted life in Antarctica
An atmospheric river brought warm, moist air to the coldest and driest corner of the planet in 2022, pushing temperatures 70 degrees above average. A new study reveals what happened to Antarctica's smallest animals.
Fungus-controlled robots tap into the unique power of nature
In creating a pair of new robots, researchers cultivated an unlikely component, one found on the forest floor: fungal mycelia. By harnessing mycelia's innate electrical signals, the researchers discovered a new way of controlling 'biohybrid' robots that can potentially react to their environment better than their purely synthetic counterparts.
Researchers identify mechanism underlying allergic itching, and show it can be blocked
Researchers identified a mechanism for why some people will itch from an allergen or mosquito bite exposure, while others will not in a new study, and showed this pathway can be targeted to prevent allergic responses in preclinical models.
‘Forever chemicals’ influence the development and function of the brain
Some per- and polyfluoroalkyl substances (PFAS) are poorly degradable and are also known as 'forever chemicals'. They adversely affect health and can lead to liver damage, obesity, hormonal disorders, and cancer. A research team has investigated the effects of PFAS on the brain. Using a combination of modern molecular biology...
New population model identifies phases of human dispersal across Europe
Researchers have developed a model that captures the dynamics of human dispersal across the continent during the last Ice Age in unprecedented detail.
Prescribing nature can improve happiness and reduce anxiety
Green Social Prescribing is the practice of supporting people with mental health needs to engage in nature-based activities. Referrals will typically come from GPs, community mental health teams, or social workers, but people can also self-refer. Social Prescribing Link Workers, and other trusted professionals, then connect people to community groups...
