Police officers are more than twice as likely to have traumatic brain injuries compared to the general population. Officers who incur these injuries while on duty face more than double the risk of developing complex post-traumatic stress disorder (PTSD). That’s according to a new survey-based study from the University of Exeter, published in The Journal of Head Trauma Rehabilitation, which found a connection between traumatic brain injuries and PTSD in police officers. Authors say the findings ...

Since cefixime and tellurite are known to inhibit most bacteria belonging to Enterobacterales, we found that addition of tellurite inhibited E. albertii growth in Luria Bertani broth but not in tryptic soy broth (TSB), and addition of phosphate and soy peptone enhanced E. albertii growth in TSB in presence of tellurite. Subsequently, to find the positive factor present in TSB, E. albertii growth was examined in tryptone, soy peptone, glucose, or phosphate deficient tryptic soy agar plates. Phosphate, soy peptone, and/or ...

Dr. Ho Seong Jang and colleagues at the Extreme Materials Research Center at the Korea Institute of Science and Technology (KIST) have developed an upconversion nanoparticle technology that introduces a core@multi-shell nanostructure, a multilayer structure in which multiple layers of shells surround a central core particle, and enables high color purity RGB light emission from a single nanoparticle by adjusting the infrared wavelength. Luminescent materials are materials that light up on their own and are used in a variety of display devices, including TVs, tablets, monitors, and smartphones, to allow us to view a variety of images ...

In today’s increasingly interconnected world, language learning has become essential for education, business, and cultural exchange. However, accurately measuring proficiency in language learners is a complex matter. One particularly valuable approach involves asking learners to listen to sentences and then repeat them back as accurately as possible. Known as elicited imitation (EI), this method reveals much more than mere memory and mimicking abilities. When sentences exceed our working memory capacity—typically beyond 8 to 10 syllables—successful repetition requires learners to quickly process and ...

The persistent higher rate of alcohol deaths in England since the pandemic in 2020 is an “acute crisis” requiring urgent action from government, according to a new study led by researchers at UCL and the University of Sheffield. For the study, published in Lancet Public Health, researchers analysed Office for National Statistics (ONS) figures of deaths caused solely by alcohol in England. They found that death rates were stable between 2009 and 2019, but increased by a fifth in 2020, rising by a further 13.5% between 2020 and 2022. The team estimated that 3,911 more people had died solely because of alcohol in England ...

Decarbonisation in the automotive and housing sectors is paramount if the UK’s legally binding commitment to achieving net zero by 2050 is to succeed, say researchers at University of Sheffield Exploring the presence of socioeconomic inequalities in the uptake of low-carbon technologies (LCTs), such as solar panels and electric vehicles, has important policy implications for the decarbonisation in the UK The new report advocates for interventions at an individual, as well as community-level, to help those from more disadvantaged backgrounds adopt technologies that ...

TAMPA, Fla. (Apr. 10, 2025) — A multi-institutional study led by Moffitt Cancer Center found that percutaneous hepatic perfusion using a melphalan hepatic delivery system may help patients with a rare eye cancer that has spread to their liver. This disease, known as metastatic uveal melanoma, is traditionally very hard to treat and usually has poor outcomes. The phase 3 FOCUS trial, published in the Annals of Surgical Oncology, compared two treatments for metastatic uveal melanoma. One group of patients received the melphalan hepatic delivery system treatment, while the other group received standard of care treatment. Patients treated with the melphalan hepatic delivery ...

Shoulders are, in many ways, a marvel. One shoulder has four separate joints, packed with muscles, that allow us to move our arm in eight different major ways, giving us the most degrees of freedom of any joint in the body. We can swim, toss, hug, and even punch because of the movement our shoulders enable. But the same complexity that allows us such motion also presents opportunities for pain when something goes wrong. Another complication: shoulders change as we age, and new types of injuries come with it. Clinical practitioners ...

Hoboken, N.J., April 10, 2025 — If you eat a snack — a meatball, say, or a marshmallow — how will it affect your blood sugar? It’s a surprisingly tricky question: the body’s glycemic response to different foods varies based on individual genetics, microbiomes, hormonal fluctuations, and more. Because of that, providing personalized nutritional advice — which can help manage diabetes, obesity, and cardiovascular diseases, among other conditions — requires costly and intrusive testing, making it hard to deliver effective care at scale. In a paper in the Journal of Diabetes Science and Technology, ...

A combined study on the morphology of the human pelvis – leveraging genetics and deep learning on data from more than 31,000 individuals – reveals genetic links between pelvic structure and function, locomotion, and childbirth outcomes, researchers report. The findings offer fresh insights into how our species evolved to balance the competing demands of bipedalism and childbirth. The transition to bipedalism in hominins led to significant changes in pelvic morphology, including a shorter and wider pelvis, which facilitated an upright posture and efficient locomotion. However, ...

A fossil Pleistocene-age hominin jawbone discovered in Taiwan has now been identified as belonging to a Denisovan, according to a new paleoproteomic analysis of the remains. The findings provide direct molecular evidence that Denisovans occupied diverse climates, from the cold Siberian mountains to the warm, humid subtropical latitudes of Taiwan, and offer new morphological insights into this enigmatic hominin lineage. Recent research has revealed a surprising variety of ancient human relatives that lived in eastern Asia during the Pleistocene before modern humans arrived. One of the most important discoveries is the Denisovans, a distinct group identified through DNA ...

Researchers from the KATRIN (Karlsruhe Tritium Neutrino) experiment report the most precise measurement of the upper mass limit of the neutrino to date, establishing it as 0.45 electron volts (eV) – less than one-millionth the mass of an electron. The findings tighten the constraints on one of the universe’s most elusive fundamental particles and push the boundaries of physics beyond the Standard Model. Neutrinos – electrically neutral elementary particles – are the most abundant particles in the universe and ...

By studying the skilled movements of marmoset tongues, researchers have discovered that Purkinje cells (P-cells) in a brain region called the cerebellum signal to stop protrusion as the tongue approaches its target, according to a study published April 10th in the open-access journal PLOS Biology by Reza Shadmehr from Johns Hopkins School of Medicine, U.S., and colleagues. We use our tongue to shape the air and generate sounds to communicate, and we use our tongue to evaluate food morsels and transport them through the oral cavity when eating. These skillful acts involve coordination of more ...
