Tiny but mighty: sophisticated next-gen transistors hold great promise

Tokyo, Japan – Hailed as one of the greatest inventions of the 20th century, transistors are integral components of modern electronics that amplify or switch electrical signals. As electronics become smaller, it is becoming increasingly difficult to continue scaling down silicon-based transistors. Has the development of our electronics hit a wall? Now, a research team led by the Institute of Industrial Science, The University of Tokyo, has sought a solution. As detailed in their new paper, to be issued in 2025 Symposium on VLSI Technology and Circuits , the team ditched the silicon and instead opted to create a transistor made from gallium-doped ...

Medieval murder: Records suggest vengeful noblewoman had priest assassinated in 688-year-old cold case

A Cambridge criminologist has uncovered new evidence in the killing of a priest, John Forde, who had his throat cut on a busy London street almost seven centuries ago. The case is among hundreds catalogued by the Medieval Murder Maps project at Cambridge University’s Institute of Criminology, a database of unnatural death in England during the 14th century. This one, however, has a few twists. Records traced by Prof Manuel Eisner suggest that John Forde’s slaying in 1337 was a revenge killing orchestrated by a noblewoman ordered to enact years of degrading penance after the Archbishop of Canterbury discovered the clergyman was her lover – possibly from ...

NIH researchers conclude that taurine is unlikely to be a good aging biomarker

Scientists at the National Institutes of Health (NIH) have found that levels of circulating taurine, a conditionally essential amino acid involved in multiple important biological functions, is unlikely to serve as a good biomarker for the aging process. In blood samples from humans, monkeys, and mice, scientists found that circulating taurine levels often increased or remained constant with age. Analysis of longitudinal data showed that within individual differences in taurine levels often exceeded age-related changes. Researchers also found that taurine levels were inconsistently associated with ...

Taurine is not a reliable biomarker for aging, longitudinal study shows

Research in animals and humans has suggested low levels of taurine may be a driver for aging, which has led to discussions about whether taurine is an aging biomarker. Now, a comprehensive study involving longitudinal data from humans, monkeys, and mice shows that taurine levels in the blood do not consistently decline with age, and that levels of taurine vary more by factors unique to each individual than based on aging. These results lead the study authors – Maria Fernandez and colleagues – to conclude that “the efficacy of taurine supplementation to delay aging ...

Dehorning of rhinos reduced poaching by 78% in Greater Kruger African reserves from 2017 to 2023

Dehorning rhinos proactively removed the incentive for poachers and reduced poaching activity by 78% across 11 Greater Kruger African reserves from 2017 to 2023, a new study has found. Conversely, law enforcement interventions designed to punish poachers retroactively had no statistical effect on poaching. “Our results present a challenge to governments, funders, the private sector, and nongovernmental organizations to reassess their strategic approaches to wildlife crime in general,” Timothy Kuiper and colleagues write. “Although detecting and arresting poachers is essential, ...

Archaeologists uncover massive 1000-year-old Native American fields in Northern Michigan that defy limits of farming

With its cold climate, short growing season, and dense forests, Michigan's Upper Peninsula is known as a challenging place for farming. But a new Dartmouth-led study provides evidence of intensive farming by ancestral Native Americans at the Sixty Islands archaeological site along the Menominee River, making it the most complete ancient agricultural site in the eastern half of the United States. The site features a raised ridge field system that dates to around the 10th century to 1600, and much of it is still intact today. The raised fields are comprised of clustered ...

Fish ‘beauty salons’ offer insight into how microbes move within reefs

Where do you go when you’re a fish and you need a skincare treatment? Coral reefs contain natural “beauty salons,” lively social hubs of activity where fish “clients” swim up and wait to be serviced by smaller fish cleaners. The little cleaners dart under and around their much bigger clients — even entering their mouths — cleaning their scales of bacteria and parasites like a team of car washers servicing a Buick. Sometimes cleaners even rub against their clients, providing a soothing massage. But aside from skincare benefits, what role might busy cleaner fish stations play in spreading microbes and bacteria — for good or ill — throughout ...

When the sky takes a midday dip: global patterns in ionospheric bite-outs

Around midday, Earth’s ionosphere sometimes experiences sharp, short-lived dips in its electron density—an unusual phenomenon known as a noontime bite-out. A new study takes a global view of these midday disruptions, using finely detailed ionospheric maps to compare their behavior in years of high and low solar activity. The research reveals that noontime bite-outs are more widespread and frequent during solar minimum, especially in winter and at higher latitudes. With detailed tracking of timing, intensity, and ...

US self-reported race and ethnicity are poor proxies of genetic ancestry

Genetic ancestry is much more complicated than how people report their race and ethnicity. New research, using data from the National Institutes of Health’s (NIH) All of Us Research Program, finds that people who identify as being from the same race or ethnic group can have a wide range of genetic differences. The findings are reported June 5 in the Cell Press journal the American Journal of Human Genetics. As doctors and researchers learn more about how genetic variants influence the incidence and course of human diseases, the study of genetic ancestry has become increasingly important. This research is driving the field of precision medicine, ...

Living towers of worms observed in nature

Nematodes are the most abundant animal on earth, but when times get tough, these tiny worms have a hard time moving up and out. So, they play to the strength of their clade. If food runs out and competition turns fierce, they slither towards their numerous kin. They climb onto each other and over one another until their bodies forge a living tower that twists skyward where they might hitch a ride on a passing animal to greener and roomier pastures. At least that’s what scientists assumed. For decades, these worm structures ...

Chimpanzees can catch yawns from androids

Chimpanzees (Pan troglodytes) can ‘catch’ yawns from an android imitating human facial expressions, according to new research from City St George’s, University of London. The study, published in Scientific Reports, demonstrates that chimpanzees will both yawn and lie down in response to yawns made by an android, suggesting that it may act as a cue to rest rather than simply triggering an automatic response. The findings appear to show contagious yawning due to an inanimate model for the first time, according to the authors, and the study also ...

Have female earwigs evolved their forceps as weapons in battles for mates?

A new study from Toho University reveals that female earwigs exhibit a similar pattern of exaggerated forceps growth as males, suggesting that both sexes may have evolved these traits through sexual selection. Do larger male elk have proportionally larger antlers? The answer is no. In fact, larger individuals tend to have disproportionately larger antlers—a phenomenon known as positive allometry. This pattern, where certain body parts grow disproportionately large relative to body size, is observed not only in mammals ...
