Even Awake, Our Brains Rest and Activate During Sleep

Biology, Science /

Scientists have made a groundbreaking discovery: a small region of our brain shuts down briefly to take microsecond-long naps while we’re awake. Interestingly, these same areas become active during sleep. These findings could provide crucial insights into neurodevelopmental and neurodegenerative diseases associated with sleep disturbances. Researchers from Washington University in St. Louis (WashU) and the […]

A Freeze-Dried Mammoth Reveals the Most Complete Ancient Genome in 3D

Biology, Science /

Scientists have created the most complete 3D reconstruction of the woolly mammoth genome, thanks to a remarkably well-preserved specimen that was “freeze-dried” immediately after death. With its DNA preserved in a glass-like state, they discovered fossilized chromosomes for the first time, enabling them to see which genes were active or inactive. While mammoths and other

Video: First-Ever Footage of a Blue Whale Nursing its Calf

Biology, Science /

The first video of a blue whale nursing her calf has been released, alongside other remarkable footage of the species’ intimate behaviors, captured in 2022 by a fortunate snorkeler. This marks the first occasion for both scientists and the public to observe these behaviors in these notoriously elusive cetaceans. These historic few seconds, filmed in

Pre-Dinosaur Predator: Gaiasia, the Giant of Permian Swamps

Biology, Science /

Long before dinosaurs dominated the Earth, another formidable predator thrived in its environment. Gaiasia, resembling a large salamander, roamed the Permian swamps. Unlike the cute axolotl, Gaiasia jennyae was a massive amphibian measuring approximately 2.5 m (8.2 ft) in length, equipped with a skull and jaw structure suggesting it could prey upon even large animals

Many of Us Are Dominantly Right-Handed but Left-Eyed. Here’s the Reason

Biology, Neuroscience, Psychology /

The study explores the complex interplay of handedness and visual biases in humans, drawing parallels with similar traits observed across the animal kingdom. While handedness is well-known as a defining characteristic, the study reveals lesser-known biases that impact social dynamics and cognitive functions. Human Biases and Brain Lateralization Humans exhibit a strong tendency towards right-handedness,

Two New Hallucinogenic Mushrooms Found

Biology, Science /

Two new hallucinogenic fungi species have been discovered and formally classified, adding to the approximately 140 known varieties of psychoactive gilled mushrooms. Researchers from Stellenbosch University, along with citizen mycologists, used phylogenetic and morphological analysis to confirm that the two mushrooms, Psilocybe ingeli and Psilocybe maluti, are novel species. These were found in southern Africa,

The Anti-Aging Compound Rejuvenates Youth Indicators Effectively

Biology, Genetics, Science /

In pre-clinical studies, a small molecule successfully stimulated neuron regeneration, decreased inflammation, and enhanced memory, speed, coordination, grip strength, and other factors. These findings hold significant promise for aging and associated diseases. Researchers at the University of Texas MD Anderson Cancer Center investigated telomerase reverse transcriptase (TERT), an enzyme crucial for synthesizing and elongating telomeres—the

New Dinosaur Named After a Deity Due to its Unique Headgear

Biology, Science /

The Natural History Museum of Utah has unveiled a previously undiscovered species of horned, herbivorous dinosaur, an ancestor of the Triceratops. Its distinctive and impressive headgear has led to it being named after a deity. Paleontologists discovered fragments of the dinosaur’s skull in 2019 in northern Montana, near the US-Canada border. As they began assembling
