Giraffes combine quantities similarly to addition
In addition to humans, some species of primates and birds have demonstrated under experimental conditions their ability to manipulate quantities in tasks that require combining or separating them, in a manner similar to addition or subtraction. Now, a study by the University of B
Dangerous temperatures forecast for parts of Europe as heatwave moves east
Red warnings issued in Hungary, Poland, Romania and the Balkans, with authorities urging people to stay indoorsParts of central, eastern and southern Europe sweltered on Monday as the “heat dome” behind last week’s record-breaking temperatures shifted east, bringing dangerous con
Table sugar could hold a cheaper, quicker key to making vital drugs
Pioneering research has developed a new way of creating carbohydrate-based medicines that could ultimately replace costly drugs for common health conditions, using two cheap basic ingredients—table sugar and vinegar.
Deep-sea extremophile yields protein that forms super stable biofilm
Scientists discovered a protein secreted by a deep-sea extremophile—an organism adapted to extreme environmental conditions—that self-assembles into a biofilm and is highly stable, boosting its potential for biomedical applications.
Grasslands could lose four times more carbon uptake under future drought conditions
The effects of individual climate factors on ecosystems are usually considered in isolation. However, in reality, they occur simultaneously and influence each other. Increasing CO2 concentrations in the atmosphere contribute to climate warming, which in turn fosters more frequent
Specieswatch: How heatwaves play havoc with bees’ fertility
Study reveals extreme heat causes sharp drop with knock-on effect for pollination of food crops in following yearsWe know heatwaves have serious health consequences for humans, but what about other species? A study has shown they severely diminish bees’ fertility, with significan
Climate resilience of brown bears over 175,000 years revealed in 3D analyses of their jaws
European brown bears are masters of survival: These animals have weathered Pleistocene climate fluctuations and survived the cycles of ice ages and interglacial periods to the present day. Zoologists have now investigated the origins of this evolutionary flexibility: 3D analyses
Beyond the dust: Families describe daily health challenges near the Salton Sea
A study examining air quality and respiratory health in communities surrounding the Salton Sea in Southern California shows how environmental conditions, poor housing quality and structural inequities combine to place children at greater risk for respiratory illness.
This spray-on powder can stop life-threatening bleeding in 1 second
A new spray-on powder developed by KAIST can stop life-threatening bleeding in about one second by instantly forming a strong gel over a wound. It works on deep and irregular injuries where conventional hemostatic products often struggle and remains effective even after years of
How winter conditions shape future jellyfish blooms
Marine scientists at the University of Chester have discovered that environmental conditions experienced by jellyfish before winter can have lasting effects on the size and intensity of jellyfish blooms many months later. The study focused on the moon jellyfish, Aurelia aurita, o
Long-lived radio outburst from black hole exhibits properties of the early universe
Short-lived sources of radio radiation in the sky, known as radio transients, can originate in the vicinity of supermassive black holes in the centers of galaxies. They are the result of processes that take place under extreme physical conditions. While most radio transients asso
