A Mysterious Group of Orcas Near Chile has Been Found, Revealing New Hunting Techniques

Biology, Science /

Off the coast of Chile, in the krill- and anchovy-rich waters influenced by the Humboldt Current, resides a rarely seen population of orcas. Through citizen science and years of diligent monitoring, a research team led by Dr. Ana García Cegarra from the Universidad de Antofagasta is beginning to uncover their mysteries—starting with their feeding habits.

Medicinal Tree Grown From a 1,000-Year-Old Cave Seed

Biology, Evolution, Science /

An international team of botanists, agriculturists, and historians has successfully cultivated a mature tree from an ancient seed discovered in an Israeli cave. In fact, in their study published in Communications Biology, the researchers detail the seed’s origin, the process of tracing its history, and the insights gained as the seed germinated and developed into

Mirrors on the Forest Floor Increase the Growth of Shaded Seedlings by 175%

Biology, Evolution, Science /

Indoor plant enthusiasts are familiar with using mirrors to direct sunlight onto plants. Now, scientists have adapted this idea to help endangered tree seedlings struggling to grow in shaded forests. The Serianthes nelsonii, a large tree native to Guam and Rota, is one of the rarest plants in the world, with only one mature tree

New Fossil Fish Species Bolsters Evidence of Earth’s Evolutionary Progress

Biology, Evolution, Science /

“Groundbreaking” new fossil research reveals that climate change, asteroids, and plate tectonics are interconnected with the origins and extinction of animals, highlighting the significant evolutionary role of these factors. A recent study published in Nature Communications links the discovery of a remarkably well-preserved ancient Devonian coelacanth in remote Western Australia to a period of intense

Suspended Animation Drug Could Extend Time in Emergencies

Biology, Science /

In a medical emergency, timely treatment is essential. However, a commonly used drug could be repurposed to induce a hibernation-like state, slowing organ damage and extending the time available to get patients to a hospital, potentially saving lives. Medical professionals often emphasize the ‘Golden Hour‘ following a traumatic injury. Though it’s not literally one hour,

Scientists have Found Out Why Humans no Longer have Tails

Biology, Science /

About 25 million years ago, an evolutionary divergence happened between our ancestors—the early humans and apes—and monkeys, leading to the loss of tails in our lineage. The specific genetic mutation behind this change, however, has been unknown until recently. In a recent study published in Nature, scientists revealed a distinct DNA mutation connected to the

DNA-Shedder Status May Impact Crime Scene Investigations

Biology, Genetics, Science /

If you’ve ever watched CSI, you know that suspects often leave incriminating DNA traces at crime scenes. However, a recent study suggests that the amount of this genetic material could also indicate a person’s guilt or innocence. The Role of Touch DNA in Crime Scenes Although we usually think of crime-scene DNA as coming from

For Improved Plant Growth, Simply Incorporate Ground Glass

Biology, Science /

Glass-fragment waste usually ends up in landfills, but that might not always be necessary. A recent study suggests that mixing ground glass particles with soil can create a plant growth medium that outperforms soil on its own. While larger glass items can be recycled into glass of the same color, small, mixed-color glass fragments are
