Sixty-six million years ago, at the end of the Cretaceous Period, an asteroid impact near the Yucat n Peninsula of Mexico triggered the extinction of all known non-bird dinosaurs. But for the early ancestors of today's waterfowl, surviving that mass extinction event was like ... water off a duck's back. Location matters, as Antarctica may

Based on the current pledges of countries for limiting their emissions of greenhouse gases, global temperatures are projected to reach 2.7 degrees Celsius beyond pre-industrial levels by the end of this century. A new review paper highlights how this would dramatically reshape the Arctic, the fastest-warming region of Earth. In 2024, annual average global air

New research using publicly-shared DNA barcodes and citizen science images have provided new evidence on the establishment and spread of a biological control agent used for the control of the major invasive shrub Lantana camara. New CABI-led research using publicly-shared DNA barcodes and citizen science images have provided new evidence on the establishment and spread
Because of climate change, harmful algal blooms are increasing in frequency and intensity. New science helps demystify the frequent harmful algal blooms in the Pacific off the coast of Chile by studying how algae species interact with each other and their environment. Harmful algal blooms, sometimes called HABs, occur when algae grow out of control.
Researchers have analyzed the soft tissue from a fossilized plesiosaur for the first time. The results show that the long-necked marine reptile had both smooth and scaly skin. This was likely so it could both swim rapidly and move along rough seabeds. Researchers at Lund University in Sweden have analysed the soft tissue from a

An international research team has discovered various mechanisms in asexual mites that generate genetic diversity and thus ensure survival. In collaboration with colleagues from international partner institutions, researchers at the University of Cologne have investigated the asexual reproduction of oribatid mites using genome sequencing techniques. They show that the key to evolution without sex in
New research shows bacteria form distinct species and maintain cohesion through frequent DNA exchange via homologous recombination. When Kostas Konstantinidis proved that many microbes -- like plants and animals -- are organized into species, he upended a long-held scientific belief. Scientists widely believed that bacteria, due to their unique genetic exchange mechanisms and the vast
Rising carbon dioxide levels affect more than just the climate; they also affect the chemistry of the oceans. When saltwater absorbs carbon dioxide, it becomes acidic, which alters the aquatic animal ecosystem. But how exactly does ocean acidification impact animals whose genetic makeup can shift depending on environmental cues? A study addresses this question through
In addition to being hypoallergenic, camel milk could potentially protect the gut from harmful enzymes and create healthier digestion.

New research from Edith Cowan University (ECU) has found that camel milk contained more naturally occurring bioactive
There's a downside to being a powerful alpha male -- at least if you're a baboon. Studies show that despite their high rank, the No. 1 males in baboon society are also some of the most stressed out, as measured by their high levels of glucocorticoid hormones. But new research reveals it's not the time
