Monash University researchers have demonstrated a new, counterintuitive way to protect atomically-thin electronics — adding vibrations, to reduce vibrations. By ‘squeezing’ a thin droplet of liquid gallium, graphene devices are painted with a protective coating of glass, gallium-oxide. This oxide is remarkably thin, less than 100 atoms, yet covers centimetre-wide…

University of Auckland Business School researcher Dr William Cheung is analysing micro-level data about people and households to examine the effects of moving house on mental well-being and stress. His study, co-authored with business analyst Daniel Wong scrutinises stress levels among adults in the Auckland region, namely homeowners and renters,…

Researchers from the University of Tsukuba have shown how adding a tiny resonator structure to an ultrafast electron pulse detector reduced the intensity of terahertz radiation required to characterize the pulse duration. To study proteins — for example, when determining the mechanisms of their biological actions — researchers need to…

Materials scientists at UNSW Sydney have shown that human pluripotent stem cells in a lab can initiate a process resembling the gastrulation phase — where cells begin differentiating into new cell types — much earlier than occurs in mother nature. For an embryo developing in the womb, gastrulation occurs at…

Hunnic peoples migrated westward across Eurasia, switched between farming and herding, and became violent raiders in response to severe drought in the Danube frontier provinces of the Roman empire, a new study argues. Hungary has just experienced its driest summer since meteorological measurements began, devastating the country’s usually productive farmland.…

Researchers at Tokyo Institute of Technology and the National Institute for Fusion Science have clarified the chemical compatibility between high temperature liquid metal tin (Sn) and reduced activation ferritic martensitic, a candidate structural material for fusion reactors. This discovery has paved the way for the development of a liquid metal…

Sea urchin larvae raised in high levels of plastic pollution die due to developmental abnormalities, new research shows. Scientists put fertilised urchin eggs in seawater with varying levels of plastic, and compared the effects of newly made PVC pellets (called nurdles) with fragments collected on beaches. In all three concentrations…

For the longest time, clinicians have treated cardiovascular disease by focusing on diabetes and blood pressure control, reducing cholesterol using medications like aspirin and statins. Despite these measures, heart disease remains the number one cause of death in the United States, with many patients having heart attacks even after their…

Cell division, i.e., the process through which a parent cell divides into two daughter cells, is fundamental to the growth, repair, and reproduction of living organisms. During cell division, chromosomes are pulled towards opposite spindle poles through the shortening of molecular ropes known as microtubules. Microtubules, which are composed of…

Millions of people across the globe regularly consume arsenic-contaminated water. Exposure to arsenic has previously been associated with the development of various cancers including skin cancer. Research on the underlying molecular mechanisms regulating arsenic-mediated carcinogenesis remains sparse. Using in vitro studies, researchers from Japan demonstrate how calcitriol, or activated vitamin…

Researchers have developed a new all-optical method for driving multiple highly dense nanolaser arrays. The approach could enable chip-based optical communication links that process and move data faster than today’s electronic-based devices. “The development of optical interconnects equipped with high-density nanolasers would improve information processing in the data centers that…

Enhancing the virtual experience with the touch sensation has become a hot topic, but today’s haptic devices remain typically bulky and tangled with wires. A team led by the City University of Hong Kong (CityU) researchers recently developed an advanced wireless haptic interface system, called WeTac, worn on the hand,…

CNN  —  The Senate passed legislation Wednesday evening to ban TikTok from US government devices, in a move designed to limit perceived information-security risks stemming from the social media app. The vote by unanimous consent approved the No TikTok on Government Devices Act, a bill authored by Missouri Republican Sen.…

Kremlin spokesman Dmitry Peskov said that if US Patriot missiles are sent to Ukraine, they would be legitimate targets for Russian forces. But he added that the US plan had not been confirmed. Peskov was asked by CNN if he held the same view as former Russian President Dmitry Medvedev, who…

Kremlin spokesman Dmitry Peskov said that if US Patriot missiles are sent to Ukraine, they would be legitimate targets for Russian forces. But he added that the US plan had not been confirmed. Peskov was asked by CNN if he held the same view as former Russian President Dmitry Medvedev, who…

CNN  —  The woman who hosted an American college student studying in France before he went missing told CNN she thinks he may have left voluntarily – a claim echoed by a French prosecutor. But the young man’s parents don’t believe that’s the case and on Wednesday, the student’s father…

CNN  —  At least three people have died and more than a dozen were left injured across Louisiana over the past 24 hours as severe weather moves across the South carving a path of destruction. A tornado touched down in New Orleans around 4 p.m. CT Wednesday, the National Weather…

CNN  —  Twitter on Wednesday permanently suspended an account that tracked the location of Elon Musk’s private jet, despite the social media company’s owner last month vowing, “My commitment to free speech extends even to not banning the account following my plane, even though that is a direct personal safety…

A new gelatinous robot that crawls, powered by nothing more than temperature change and clever design, brings “a kind of intelligence” to the field of soft robotics. The inchworm-inspired work is detailed today in Science Robotics. “It seems very simplistic but this is an object moving without batteries, without wiring,…

Scientists at Scripps Research and Massachusetts Institute of Technology (MIT) have found a clue to the molecular cause of Alzheimer’s — a clue that may also explain why women are at greater risk for the disease. In the study, reported on December 14, 2022, in Science Advances, the researchers found…

Human bipedalism — walking upright on two legs — may have evolved in trees, and not on the ground as previously thought, according to a new study involving UCL researchers. In the study, published today in the journal Science Advances, researchers from UCL, the University of Kent, and Duke University,…

People with cluster headaches may be more than three times more likely to have other medical conditions such as heart disease, mental disorders and other neurologic diseases, according to a study published in the December 14, 2022, online issue of Neurology®, the medical journal of the American Academy of Neurology.…

Two randomized, placebo-controlled trials evaluating three Ebola vaccine administration strategies in adults and children found that all the regimens were safe in both age groups, according to results published today in the New England Journal of Medicine. Antibodies were produced in response to the vaccine regimens beginning at 14 days…

A new study published on Dec. 14, 2022 in the New England Journal of Medicine reports the identification of a previously unknown genetic cause of a late-onset cerebellar ataxia, a discovery that will improve diagnosis and open new treatment avenues for this progressive condition. Late-onset cerebellar ataxias (LOCA) are a…

When it comes to studying food and diet, it’s difficult to know what people are eating — let alone their risk of disease caused by what they eat. Doctors and researchers usually ask people to fill out a long-from food frequency questionnaire that estimates caloric intake, food groups and nutrients.…

A single particle has no temperature. It has a certain energy or a certain speed — but it is not possible to translate that into a temperature. Only when dealing with random velocity distributions of many particles, a well-defined temperature emerges. How can the laws of thermodynamics arise from the…
