Long obscured in the shadows of history, the world’s first nomadic empire - the Xiongnu - is at last coming into view thanks to painstaking archaeological excavations and new ancient DNA evidence. Arising on the Mongolian steppe 1,500 years before the Mongols, the Xiongnu empire grew to be one of Iron Age Asia’s most powerful political forces - ultimately stretching its reach and influence from Egypt to Rome to Imperial China. Economically grounded in animal husbandry and dairying, the Xiongnu were famously nomadic, building their empire on the backs of horses. ...

The 2022 eruption of a submarine volcano in Tonga was more powerful than the largest U.S. nuclear explosion, according to a new study led by scientists at the University of Miami Rosenstiel School of Marine, Atmospheric, and Earth Science and the Khaled bin Sultan Living Oceans Foundation.   The 15-megaton volcanic explosion from Hunga Tonga-Hunga Ha'apai, one of the largest natural explosions in more than a century, generated a mega-tsunami with waves up to 45-meters high (148 feet) along the coast of Tonga’s Tofua Island and waves up to 17 meters (56 feet) on Tongatapu, ...

UNIVERSITY PARK, Pa. — New research provides insight into how an enzyme that helps regulate aging and other metabolic processes accesses our genetic material to modulate gene expression within the cell. A team led by Penn State researchers have produced images of a sirtuin enzyme bound to a nucleosome—a tightly packed complex of DNA and proteins called histones—showing how the enzyme navigates the nucleosome complex to access both DNA and histone proteins and clarifying how it functions in humans and other animals.  A paper describing the results appears April 14 in the journal ...

BOSTON – New research from Boston Medical Center concluded that offering medications to treat opioid addiction in jails and prisons leads to a decrease in overdose deaths. Published in JAMA Network Open, the study also found that treating opioid addiction during incarceration is cost-effective in terms of healthcare costs, incarceration costs, and deaths avoided. Overdoses kill more than 100,000 people per year in America and this number continues to increase every year. People with addiction are more likely to be incarcerated than treated, with those from communities of color who use drugs more likely to be incarcerated than ...

Young babies and newborn mice can naturally heal damage to the bones that form the top of the skull, but this ability is lost in adults. In a new study published in Proceedings of the National Academy of Sciences, University of Pittsburgh researchers developed a novel approach that promoted bone regeneration in mice without implantation of bone tissue or biomaterials. The technique uses a device similar to an orthodontic wire used to realign teeth to carefully stretch the skull along its sutures, activating ...

When it comes to height, our fate is sealed along with our growth plates—cartilage near the ends of bones that hardens as a child develops. Research publishing April 14 in the journal Cell Genomics shows that cells in these plates determine the length and shape of our bones and can hint at our stature. The study identified potential "height genes" and found that genetic changes affecting cartilage cell maturation may strongly influence adult height. "The study is really understanding ...

Associate Professor Jonathan Boreyko leads a team at Virginia Tech that has built a strong portfolio of work with ice and water, exploring the possibilities for de-icing planes, building novel water harvesting devices, and creating snow globes out of bubbles. This familiarity with water has given the team a strong sense of its behavior in different states, leading to a new project that shows how ice quenches heat in comparison to water. The findings were published in Chem on April 14. Mojtaba Edalatpour and master’s student Camryn ...

Chronic conditions such as type 2 diabetes, asthma, HIV infection, and mental illness may be greatly undertreated in the U.S. jail and prison population, suggests a new study from researchers at the Johns Hopkins Bloomberg School of Public Health. For their analysis, the researchers used national health survey data covering 2018 to 2020 to estimate rates of chronic conditions among recently incarcerated people, and a commercial prescription database to estimate the distribution of medication treatments to the jail and prison population. Their analysis suggests ...

Researchers from the University of Eastern Finland, the University of Turku, and Tampere University have developed an artificial intelligence-based method for virtual staining of histopathological tissue samples as a part of the Nordic ABCAP consortium. Chemical staining has been the cornerstone of studying histopathology for more than a century and is widely applied in, for example, cancer diagnostics. “Chemical staining makes the morphology of the almost transparent, low-contrast tissue sections visible. Without it, analysing tissue morphology is almost impossible for human vision. Chemical staining is irreversible, and in most ...

Québec City, April 14, 2023 - Fuchs' endothelial corneal dystrophy, a degenerative eye disease, causes progressive vision loss that can induce blindness. It is the leading cause of corneal transplantation, but the scarcity of grafts hinders its treatment. A research team from Université Laval and Université de Montréal has identified a way to slow the disease and even avoid transplantation if diagnosed at an early stage.  In people with the disease, the endothelial cells at the back of the cornea die more quickly than in healthy people. "Everyone loses them at a slow rate, slow enough to make it to the end of our lives ...
