Ants Carry Spotted Lanternfly DNA in Honeydew, Helping Detect Infestations

Biology /

Virginia might have a new partner in battling one of its most destructive insect pests. Researchers at Virginia Tech, led by Assistant Professor Scotty Yang from the Department of Entomology, have discovered a method to use ants to detect the presence of spotted lanternflies in new regions. Published in Pest Management Science and Neobiota, new […]

Scientists Discover Hidden Loading Dock Structure Within Human Cells

Biology /

Researchers at the University of Virginia (UVA) have discovered a previously unknown organelle—an ultra-small, specialized structure inside human cells that plays a role in recycling cellular material. This breakthrough could pave the way for new treatments for a variety of diseases. Just like our bodies rely on organs to perform vital tasks, our cells contain

Wildlife Forensics Team Unveils Method to Spot Elephant Ivory Masquerading as Mammoth Ivory

Biology, Evolution /

In an effort to protect elephants from extinction, the global community banned the trade of elephant ivory. However, mammoth ivory remains legal to sell, and the two types are hard to distinguish—particularly for those without expertise. This creates a potential loophole that illegal ivory traders can take advantage of. Stable isotope analysis may now offer

Scientists Develop Genetically Engineered Mosquito STD to Help Fight Malaria

Biology /

Mosquitoes have been one of humanity’s deadliest foes for millennia, responsible for more deaths than any other animal. As mosquitoes grow increasingly resistant to conventional control strategies, scientists are turning to novel solutions to fight mosquito-borne illnesses. Genetically Modified Fungus Targets Malaria-Carrying Mosquitoes At the University of Maryland, entomologists have genetically modified a fungus to

Blood Clotting Discovery Heralds A “New Era In Vascular Biology”

Biology, Evolution /

Scientists have uncovered a previously unrecognized biological process responsible for tissue and organ damage in low-oxygen conditions like heart attacks and strokes. The findings indicate that rupturing red blood cells, rather than blood clots, are to blame. The microvasculature—a network of tiny blood vessels—is essential for supplying oxygen and nutrients to body tissues. When these

New Bioluminescent Virus Sensor Is 515 Times More Efficient Than Earlier Techniques

Biology, Cell Biology /

Animals that generate their own light through internal chemical reactions are one of nature’s marvels—and scientists have long sought to replicate this for human applications. Now, researchers at Mass General Brigham have made a major leap by tweaking the chemistry behind the glow, creating a  bioluminescence diagnostic tool that’s 515 times brighter and lasts eight

Dolphins Create Their Own “Names” That May Carry Hidden Information

Biology, Science /

Just like humans, many animals rely on social interactions to survive and thrive. As a result, effective communication between individuals is essential. Highly social species tend to develop more complex communication systems. Think of chimpanzees using gestures and vocalizations, or elephants exchanging information through touch and low-frequency calls. Bottlenose dolphins live in complex social structures,

Giant Megalodon’s Prey Finally Revealed — And It’s Not What We Thought

Biology, Plants & Animals, Science /

The massive Megalodon, one of the greatest predators of the Neogene period, ruled the oceans for about 20 million years before vanishing. During that time, it fed on virtually any marine creature large enough to become a meal. New Evidence Challenges Old Assumptions That’s the conclusion of a new study that analyzed fossilized Megalodon teeth
