Recent scholarship has concluded that Neanderthals made a second major migration from Eastern Europe to Central and Eastern Eurasia between 120,000 and 60,000 years ago. But the routes they took have long been a mystery—primarily because there are few archaeological sites connecting the two regions.  In a new analysis, a team of anthropologists—using computer simulations—has offered a map of possible pathways, which concludes Neanderthals likely used river valleys as natural highways and traveled during warmer periods to move approximately 2,000 miles (3,250 km) in less than 2,000 years.  “Our findings show that, despite obstacles like mountains ...

A new study from The University of Texas at Arlington details a novel strategy for how the body clears out dead cells during stress, revealing unexpected roles for well-known stress-response genes—a discovery that could help scientists better understand diseases affecting the immune system, brain and metabolism.   “The body is constantly creating new cells and removing old cells once they die,” said Aladin Elkhalil, lead author of the study and a third-year doctoral student in the lab of Piya Ghose, ...

DARIEN, IL – A new study to be presented at the SLEEP 2025 annual meeting found that teens with earlier, more efficient, and less variable sleep patterns at age 15 had better cardiovascular health at age 22. Results show that several healthy sleep habits at age 15 predicted a higher (better) cardiovascular health score at age 22: falling asleep and waking up earlier, spending a lower percentage of time in bed awake, and having lower variability in total sleep time and sleep onset. In contrast, average total sleep time did not predict future cardiovascular health. Results were adjusted for potential confounders ...

Cancer cannot be understood as a single, uniform disease. The more we delve into studying each type of tumor, the more we recognize the need to subclassify the disease. This concept has led to what we now call precision oncology, characterizing the molecular features of a patient's specific cancer to determine the most effective treatment. Prostate cancer is considered the most prevalent tumor among men, and it typically has a high cure rate. As such, although many men will be diagnosed with this cancer, the majority will be cured. "However, when we refer ...

Stress worsens sleep quality and can impair memory. Shinjae Chung, from the University of Pennsylvania, led a study to explore a neural pathway in male mice that stress may influence to cause sleep and memory disturbances.   In their JNeurosci paper, the researchers artificially activated neurons in the paraventricular nucleus of the hypothalamus (PVN) that were previously linked to stress. This experimental manipulation made mice sleep less and impaired how well mice performed in a memory task. Notably, when mice were stressed, artificially inhibiting these PVN neurons reduced stress-related memory ...

Guns are now the leading cause of death for youth in the United States. Researcher from Mass General Brigham investigated whether firearm mortality rates among U.S. children ages 0-17 changed in the 13 years following a 2010 Supreme Court ruling that applied the Second Amendment to state and local governments. In states with the most permissive firearm laws, they found evidence of 6,029 more pediatric deaths due to firearms than would have been expected based on the existing demographic trends—and more than 1,400 excess ...

Imagine having to eat something that makes you sick – just to see what’s making you ill in the first place.  That’s the harsh reality of current diagnostic tests for coeliac disease, which require people to eat large amounts of gluten for weeks in order to get an accurate diagnosis. But this painful process could soon be a thing of the past, with WEHI researchers and industry partner Novoviah Pharmaceuticals developing a world-first blood test that can identify the condition in patients – even when they’re on gluten-free diets.   At a glance New clinical research published in the high-impact ...

Tokyo, Japan – Across the world the demand for meat is growing, despite associated environmental and animal welfare costs. Although lab-grown – or cultured – meat could be part of the answer, scientists have yet to perfect one crucial detail: the taste. In an article to be published in Food Chemistry, researchers from the Institute of Industrial Science, The University of Tokyo, have measured and found a way to control the key amino acids responsible for flavor in a step toward making cultured meat taste just like the real thing. The push toward cultured meat has been adopted because conventional production is not a sustainable solution for ...

Even with today’s advanced agricultural technologies, plant diseases can still be extremely devastating to crops, causing billions of dollars in losses worldwide every year. Begomoviruses represent a prominent example of this threat—these whitefly-transmitted pathogens cause yellow leaf curl disease in peppers and can destroy up to 100% of fruit yield in affected fields across Asia, Africa, and the Americas. Breeding crops that are resistant to begomoviruses has long been the most effective and widely used strategy for preventing such massive losses. Though usually effective, this approach has serious limitations, especially when dealing with mixed infections. Scientists ...

Kyoto, Japan -- After the island of Madagascar drifted away from India 88 million years ago, isolating it from all other landmasses, its flora and fauna evolved in seclusion. As these transformed into plants and animals completely unique to their island, Madagascar became a biodiversity hotspot unlike anywhere else on Earth. An important facet of this biodiversity is an ecological process called endozoochory, which is when animals eat plant seeds and then poop them out somewhere else, aiding in the spread of the plants. Most research on endozoochory has focused on the roles of ...

Brain-computer interface (BCI) technology is opening an unprecedented chapter in human-machine integration by establishing direct communication between the brain and external devices. Once a science fiction concept, BCI is now reshaping the landscape of neurosurgery and neurorehabilitation. By decoding brain signals to restore lost motor, sensory, and language functions, BCIs offer new hope for individuals affected by paralysis, aphasia, and neurodegenerative diseases. But their impact extends well beyond the clinic—BCIs are poised to influence cognition, ethical governance, and national security. As this disruptive technology matures, ...

Plant fossils found in the abdomen of a sauropod support the long-standing hypothesis that these dinosaurs were herbivores, finds a study publishing June 9 in the Cell Press journal Current Biology. The dinosaur, which was alive an estimated 94 to 101 million years ago, ate a variety of plants and relied almost entirely on its gut microbes for digestion.   “No genuine sauropod gut contents had ever been found anywhere before, despite sauropods being known from fossils found on every continent and despite the group ...

Two topical treatments applied to kids’ cavities can stop the majority of them from progressing for years, according to a study led by NYU College of Dentistry and published in JAMA Network Open. Treating more than 10,000 cavities in New York City elementary school students, the researchers found that both atraumatic restorations (ART) and silver diamine fluoride (SDF) kept most dental decay from worsening, supporting the use of non-surgical approaches for managing cavities. Children miss an estimated 34 million hours of school each year due to emergency dental care. Bringing cavity prevention programs to schools can improve kids’ oral health and stave ...

In one of the largest and most comprehensive studies of its kind, a research team led at UC San Francisco has identified the regions where dementia occurs most often.  What They Discovered Using the Mid-Atlantic* as the basis for comparison, researchers found that dementia rates were 25% higher in the Southeast.** The Northwest*** and Rocky Mountains**** were both 23% higher, and the South***** was 18% higher. The Southwest, which includes California, was 13% higher; while the Northeast, which includes New York, was 7% higher.  These differences remained when researchers accounted for factors like age, ...

In 2017, scientists at Cincinnati Children’s revealed that using antibiotics to protect newborns from dangerous infections often comes with a long-term consequence—a permanently underdeveloped immune system that can make children prone to poor outcomes from future lung infections. Now a study published June 9, 2025, in Cell, details the mechanisms behind antibiotic-related immune disruptions, which in turn suggests a way to reverse or minimize the risk. "These remarkable findings indicate that we might be able to protect at-risk infants through targeted supplementation," says senior author Hitesh Deshmukh, MD, PhD, a neonatologist with the Perinatal ...

Background IVD is a key enzyme in leucine catabolism, catalyzing the conversion of isovaleryl-CoA to 3-methylcrotonyl-CoA. Defects in IVD function lead to toxic accumulation of metabolites such as isovaleric acid, resulting in isovaleric acidemia (IVA)—a life-threatening autosomal recessive disorder characterized by vomiting, metabolic acidosis, and neurological damage. Although IVD gene mutations are known to cause IVA, the enzyme's structural dynamics and complex substrate-binding mechanisms have long hindered ...
