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 […]

Man Voluntarily Bitten by Snakes 200 Times Inspires New Hope for Antivenom Development

Biology /

Feeling especially low the day after the September 11 attacks, Tim Friede went to his basement and allowed himself to be bitten by two of the world’s most venomous snakes. Four days later, Tim Friede awoke from a coma. “I know what it feels like to die from a snakebite,” he told AFP in a

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,

Spectacular Cat-Sized Rat Caught On Video For The Very First Time

Biology, Science, Zoology /

A rare, large nocturnal rodent living in mountainous regions has been filmed and photographed for the first time — an impressive milestone for zoology, comparable to winning the scientific lottery. The animal had only been seen once in the past 30 years, with descriptions limited to a few museum specimens. Scientific expedition to uncover New

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

Doctors Used first Personalized Gene-editing Therapy on Baby

Biology, Genetics /

A team of doctors and scientists has successfully treated a rare genetic disorder using the first personalized gene-editing therapy. The results, published in The New England Journal of Medicine, were accompanied by an editorial from a former FDA gene-therapy regulator. The patient in this landmark case was KJ, an infant diagnosed with CPS1 deficiency—a condition

First-ever Gene-edited Spider Creates red Fluorescent Silk

Biology, Evolution /

Scientists at the University of Bayreuth have successfully engineered the world’s first spider modified with CRISPR-Cas9 to produce red fluorescent silk. They achieved this using the common house spider species Parasteatoda tepidariorum. Spiders’ cannibalistic behavior and complex genomes make them hard to modify and breed in labs, limiting their use in research. To overcome this,

Flamingos Stir up Whirlpools with their Feet and Beaks to Catch Prey

Biology, Zoology /

When we think of a flock of flamingos, we usually picture their long pink legs standing in shallow water and their heads down as they feed. While it may seem calm, there’s actually a flurry of activity underwater. With their webbed feet and uniquely angled beaks, flamingos create swirling mini-tornadoes to trap prey. A recent
