Hormonal Differences May Explain Gender Disparity in Opioid Misuse

The opioid epidemic has devastated communities across the United States, claiming the lives of over half a million people since 1999. Of those deaths, approximately three-quarters are men, according to the National Institutes of Health. This gender disparity in opioid misuse and overdose rates is well documented, but the underlying reasons for why men are … Read more

Study Reveals Thalamic Dominance in Behavioral State Encoding

Researchers at the National Institutes of Health (NIH) have made a significant breakthrough in understanding how individual neurons in the primary somatosensory cortex receive brain-wide presynaptic inputs that are involved in encoding behavioral states. This work refines our understanding of cortical activity and challenges previous theories about how sensory information processing and motor control are … Read more

New Study Revises Megalodon Size and Shape Estimates

A groundbreaking study led by Professor Kenshu Shimada of DePaul University has provided new insights into the biology of the prehistoric giant shark Megalodon (Otodus megalodon), which once roamed the oceans globally from about 15 million to 3.6 million years ago. The study, conducted in collaboration with 28 experts in shark biology, paleontology, and vertebrate … Read more

Peruvian Fossils Uncover Megalodon’s Diet and Demise

A team of international researchers from Italy, Belgium, and Peru has uncovered new evidence that sheds light on one of the ocean’s greatest mysteries: the extinction of the giant prehistoric shark known as megalodon. This massive predator, whose scientific name is Otodus megalodon, once dominated the oceans from approximately 17 million to 2.6 million years … Read more

How Lost Nurseries Led to Megalodon’s Demise

For millions of years, Otodus megalodon, the largest predatory shark ever known, ruled the world’s oceans. These massive creatures were the undisputed apex predators of their time, terrorizing seas from the Miocene through the Pliocene epochs. But while the adult megalodon was a near-unstoppable force, dominating its marine ecosystem with sheer size and power, its … Read more

Megalodon’s Teeth Were Weaker Than Thought, Study Finds

A groundbreaking new study led by researchers at the University of Bristol has shed light on the mysterious evolution of the iconic prehistoric shark Megalodon, suggesting that the massive size of its teeth was less about changing dietary habits and more a side effect of the shark’s monumental growth. This discovery challenges long-held assumptions about … Read more

34,000-Year-Old Mongolian Skull Reveals Complex Human Migration

In a groundbreaking study that reshapes our understanding of early human migration and interaction, scientists have analyzed the genome of the oldest human fossil ever found in Mongolia. This ancient individual, a woman who lived roughly 34,000 years ago, has provided valuable insight into the movements and relationships of early populations across the vast expanse … Read more

Ancient Czech Skull of Zlatý Kůň Yields Oldest Modern Human Genome

Recent advances in ancient DNA research have significantly enhanced our understanding of human history, revealing fascinating insights into the interactions between early modern humans and Neanderthals. Studies have shown that these two groups likely interbred in the Near East around 50,000 years ago, soon after modern humans began migrating out of Africa. This interbreeding has … Read more
