Experiments show gray seals can monitor their own blood oxygen levels to prevent drowning
A team of scientists with the Sea Mammal Research Unit, School of Biology, University of St Andrews, in the U.K. has found that gray seals are able to monitor their blood oxygen levels as a means to prevent drowning. In their ...
We found a new wasp! Students in Australia are discovering insect species through citizen science
Playgrounds can host a variety of natural wonders, and of course, kids. Now some students are not just learning about insects and spiders at school—they are putting them on the map and even discovering and naming new species.

Two bees or not two bees? How wild bees feel the sting of honeybee competition
Researchers from the University of Florence and University of Pisa conducted an experiment demonstrating that managed honeybees (Apis mellifera) on Giannutri Island significantly deplete nectar and pollen availability, leading ...
Massive, long-lived trees discovered in the Tanzanian rainforest are a new species
A team of botanists with members from Muse–Museo delle Scienze, Udzungwa Corridor LTD, Via Grazia Deledda and the National Museum of Kenya has discovered a new species of tree growing in the mountainous rain forests of ...
Deadly bacteria have developed the ability to produce antimicrobials and wipe out competitors, scientists discover
A drug-resistant type of bacteria that has adapted to health care settings evolved in the past several years to weaponize an antimicrobial genetic tool, eliminating its cousins and replacing them as the dominant strain. University ...
