– By Alison Hatt The prospect of a quantum internet, connecting quantum computers and capable of highly secure data transmission, is enticing, but making it poses a formidable challenge. Transporting quantum information requires working with individual photons rather than the light sources used in conventional fiber optic networks. To produce and manipulate individual photons, scientists are turning to quantum light emitters, also known as color centers. These atomic-scale defects in semiconductor materials can emit single photons of fixed wavelength or color and allow photons to interact with electron spin properties in controlled ways.  A team ...

Bacteria live in nearly every habitat on earth including within soil, water, acidic hot springs and even within our own guts. Many are involved in fundamental processes like fermentation, decomposition and nitrogen fixation. But scientists don’t understand a fundamental process within bacteria cells: how they organize themselves before division. Driving vs. surfing When cells divide the cell splits into two “daughter cells” with the same genetic material as the original cell. During this process, the DNA and other cellular components replicate, and then this “cargo” ...

In humans, the SLC29A3 gene regulates the function of lysosomes to control waste recycling in cells such as macrophages (that engulf and destroy foreign bodies). This gene encodes for the lysosomal protein that transport nucleosides — degradation products of RNA and DNA — from lysosomes to the cytoplasm.  Loss-of-function mutations in the SLC29A3 gene lead to aberrant nucleoside storage, resulting in a spectrum of conditions called SLC29A3 disorders. These disorders can manifest in the form of pigmented skin patches, enlargement of the liver/spleen, hearing loss, or type 1 diabetes. A key manifestation of this group of disorders is histiocytosis, ...

Bottom Line: The U.S. Preventive Services Task Force (USPSTF) recommends that clinicians prescribe preexposure prophylaxis using effective antiretroviral therapy to persons at increased risk of HIV acquisition to decrease the risk of acquiring HIV. An estimated 1.2 million persons in the U.S. currently have HIV, and more than 760,000 persons have died of complications related to HIV since the first cases were reported in 1981. Although treatable, HIV is not curable and has significant health consequences. Therefore, effective strategies to prevent HIV are an important public health and ...

DURHAM, N.C. -- A few years ago while on a fishing trip in the Florida Keys, biologist Lori Schweikert came face to face with an unusual quick-change act. She reeled in a pointy-snouted reef fish called a hogfish and threw it onboard. But later when she went to put it in a cooler she noticed something odd: its skin had taken on the same color and pattern as the deck of the boat. A common fish in the western Atlantic Ocean from North Carolina to Brazil, the hogfish is known for its color-changing skin. ...

A new powerful antibiotic, isolated from bacteria that could not be studied before, seems capable to combat harmful bacteria and even multi-resistant ‘superbugs’. Named Clovibactin, the antibiotic appears to kill bacteria in an unusual way, making it more difficult for bacteria to develop any resistance against it. Researchers from Utrecht University, Bonn University (Germany), the German Center for Infection Research (DZIF), Northeastern University of Boston (USA), and the company NovoBiotic Pharmaceuticals (Cambridge, USA) now share the discovery of Clovibactin and its killing mechanism in the scientific journal Cell. Urgent need for new antibiotics Antimicrobial ...

WASHINGTON, August 22, 2023 – Millions of people around the world experience some form of hearing loss, resulting in negative impacts to their health and quality of life. Treatments exist in the form of hearing aids and cochlear implants, but these assistive devices cannot replace the full functionality of human hearing and remain inaccessible for most people. Auditory experiences, such as speech and music, are affected the most. In JASA, published on behalf of the Acoustical Society of America by AIP Publishing, researchers from the University of Oldenburg studied the impact of hearing loss on subjects’ enjoyment of different ...

LA JOLLA (August 22, 2023)—The prevalence of colorectal cancer in people under the age of 50 has risen in recent decades. One suspected reason: the increasing rate of obesity and high-fat diets. Now, researchers at the Salk Institute and UC San Diego have discovered how high-fat diets can change gut bacteria and alter digestive molecules called bile acids that are modified by those bacteria, predisposing mice to colorectal cancer.   In the study, published in Cell Reports on August 22, 2023, the team found increased levels of specific gut bacteria in mice fed high-fat diets. Those gut bacteria, they ...

(Boston)—For more than 100 years, it has been believed that sunlight and vitamin D deficiency were associated with the risk for many deadly cancers including colorectal, prostate and breast. But some scientists remained skeptical that this nutrient provides any benefit for reducing cancer risk and morbidity and mortality and several randomized controlled trials that have supported this doubt.  However, in a new commentary in JAMA Network Open, Michael F. Holick, PhD, MD, professor of medicine, pharmacology, physiology & biophysics and molecular medicine at Boston University Chobanian & Avedisian School of Medicine, explores the controversy as to ...

For people who have experienced a heart attack or stroke, taking a daily aspirin has been shown to help prevent a second one. Yet, despite aspirin’s low cost and its clear benefits in such scenarios, fewer than half of people worldwide who have had a heart attack or stroke take the medication, according to a new study led by researchers at Washington University School of Medicine in St. Louis and the University of Michigan. The study appears Aug. 22 in JAMA. Cardiovascular disease, including heart attack and ...

While COVID-19 lockdowns are no longer mandated, the stress and anxiety of the pandemic still lingers, especially among young South Australians, say health experts at the University of South Australia.   In a new study released today, researchers show that children’s mental health and wellbeing have gradually worsened over the past six years, particular during and post the pandemic.   Examining measures of wellbeing – life satisfaction, optimism, happiness, cognitive engagement, emotional regulation, perseverance, worry, and sadness – ...

The Venus flytrap can survive in the nutrient-poor swamps of North and South Carolina because it compensates for the lack of nitrogen, phosphate and minerals by catching and eating small animals. It hunts with snap traps that have sensory hairs on them. If an insect touches these hairs two times, the traps shut and digests the prey. In its location in the swamp, the carnivorous plant is often not visible because it is overgrown by grass. In summer, the grass dries up. Then it can catch fire from the frequent lightning storms typical of North Carolina – ...
