UNIVERSITY PARK, Pa. — A new twist on a classic material could advance quantum computing and make modern data centers more energy efficient, according to a team led by researchers at Penn State.    Barium titanate, first discovered in 1941, is known for its powerful electro-optic properties in bulk, or three-dimensional, crystals. Electro-optic materials like barium titanate act as bridges between electricity and light, converting signals carried by electrons into signals carried by photons, or particles of light.   However, despite its promise, barium titanate never became the industry standard for electro-optic devices, such as modulators, switches and ...

The drug development pipeline is a costly and lengthy process. Identifying high-quality “hit” compounds—those with high potency, selectivity, and favorable metabolic properties—at the earliest stages is important for reducing cost and accelerating the path to clinical trials. For the last decade, scientists have looked to machine learning to make this initial screening process more efficient. Computer-aided drug design is used to computationally screen for compounds that ...

Staying cool during heatwaves is challenging for small creatures, but the problem could be even more extreme for nocturnal creatures that are unable to move to cooler locations while slumbering. ‘Roosting bats may face lethally high body temperatures during extremely hot days’, says Ruvinda de Mel, from the University of New England, Australia. And bat boxes are often designed to retain heat to keep bats cozy, which could place the animals at even greater risk during heatwaves, depending on the box’s position ...

Researchers at the University of Chicago have found that patients with violent injuries often face legal and financial needs that can have an impact on their recovery—and that providing legal help at the bedside can make a measurable difference. The study, published in JAMA Network Open, evaluated the Recovery Legal Care program at the University of Chicago Medical Center, the nation’s first medical-legal partnership embedded in a trauma center. The team of UChicago investigators, led by ...

In the hunt for new therapeutics for cancer and infectious diseases, lasso peptides prove to be a catch. Their knot-like structures afford these molecules high stability and diverse biological activities, making them a promising avenue for new therapeutics. To better unleash their clinical potential, a team from the Carl R. Woese Institute for Genomic Biology developed LassoESM, a new large language model for predicting lasso peptide properties. The collaborative study was recently published in Nature Communications. Lasso peptides are natural products made by bacteria. To produce these peptides, bacteria use ribosomes to build chains of amino acids that are then folded by biosynthetic ...

A new study from researchers at Washington University School of Medicine in St. Louis provides some answers. Published Sept. 15 in Nature Mental Health, it mined an enormous set of data collected from pre-teens and teens across the U.S. and found that social conflicts — particularly family fighting and reputational damage or bullying from peers — were the strongest predictors of near- and long-term mental health issues. The research also revealed sex differences in how boys and girls experience stress from ...

Key Takeaways An evaluation of 50 surgical QI projects found that only one scored above 70% on criteria for a well-conducted effort, with major deficits in the critical early "front-end" planning stage. The new EPoSSI framework provides a structured, nine-step guide and checklist to help clinicians systematically plan projects before launch. In testing, using the full EPoSSI tool (diagram and guidance table) led to an increase in planning comprehensiveness, with participants meeting 100% of scoring criteria compared to just 24% without the framework. CHICAGO ...

Political attitudes and opinions can and do shift, sometimes drastically. Recent psychological research from Washington University in St. Louis offers insight into how emotional responses to threats contribute to shifts in political attitudes. One striking example of how emotions drive political shifts is that people tend to become more supportive of conservative views during times of external, or foreign, threat. Immediately after the 9/11 attacks, for example, national polls showed that support for President George W. Bush — a moderately conservative Republican — soared by 39 points to a record-breaking ...

Like us humans, insects possess sensory organs responsible for vision, hearing, smell, taste, and touch. For vision, insects primarily rely on compound eyes. But what about hearing? For example, crickets develop tympanal organs on their forelegs, which function like a human’s eardrum to detect sound. They use these “ears on the legs” to listen to courtship songs and sense approaching enemies.   The tympanal organs have evolved in insects repeatedly. For example, cicadas, grasshoppers, moths and mantises have tympanal ears on their abdomen or thorax. Uniquely, stinkbugs of the family Dinidoridae, encompassing around 100 species representing ...

Sleep-like slow-wave patterns persist for years in surgically disconnected neural tissue of awake epilepsy patients, according to a study published October 16th in the open-access journal PLOS Biology by Marcello Massimini from Universita degli Studi di Milano, Italy, and colleagues. The presence of slow waves in the isolated hemisphere impairs consciousness, however, whether they serve any functional or plastic role, remains unclear. Hemispherotomy is a surgical procedure used to treat severe cases of epilepsy in children. The ...

In a Policy Forum, David Victor and colleagues outline a framework for incentivizing meaningful investments into high-risk, transformative clean technologies in the aviation industry. While massive reductions in global emissions are needed to combat climate change, most current clean investments focus on low-risk, mature technologies such as renewable energy, batteries, and electric vehicles. However, many sectors, including aviation, which accounts for about 3% of global emissions, face steep technological and economic barriers to decarbonization, making ...

What looked like a hearing organ on a tiny stinkbug’s leg turned out to be something far stranger: a fungal nursery that mother bugs use to coat their newly laid eggs in protective symbiotic hyphae, shielding their offspring from parasitic wasps. Tympanal organs have repeatedly evolved in many insect species and are often considered to be used for sensing sound. Previous studies have reported a conspicuously enlarged structure on the real legs of adult female dinidorid stinkbugs, which has long been interpreted as a tympanal ...

Although many ecosystems can weather several years of moderate drought, consecutive years of extreme dryness push them past a tipping point, resulting in dramatic declines in plant growth, researchers report. The findings – borne from a global experiment spanning six continents – reveal threats to Earth’s grasslands and shrublands as climate extremes intensify. Although most droughts are brief and moderate, the most ecologically and economically damaging events are both prolonged and extreme. Evidence suggests such extreme events are becoming more frequent with ongoing climate change. However, the effects of multi-year ...

Cutting planet-warming pollution to near-zero will take more than inventing new clean technologies—it will require changing how the world invests in them. That’s especially true for industries like aviation, where developing and adopting greener solutions is risky and expensive, according to a University of California San Diego commentary piece in Science.  The paper calls for smarter ways of managing investment risk could help speed up the shift toward cleaner air travel and other hard-to-decarbonize sectors.   “The aviation sector—a ...

A research team led by Prof. BI Guo-Qiang from the University of Science and Technology of China (USTC) of the Chinese Academy of Sciences (CAS), in collaboration with several domestic and international institutions, has resolved a 50-year-old controversy in neuroscience. By employing a self-developed, time-resolved cryo-electron tomography (cryo-ET) technique, the team has delineated the intricate choreography of synaptic vesicle (SV) release and rapid recycling, the cornerstone of neural communication. Their findings, which introduce a new biophysical mechanism termed the “Kiss-Shrink-Run”, ...

CORVALLIS, Ore. — Large changes in global sea level, fueled by fluctuations in ice sheet growth and decay, occurred throughout the last ice age, rather than just toward the end of that period, a study publishing this week in the journal Science has found. The findings represent a significant change in researchers’ understanding of how the Pleistocene – the geological period from about 2.6 million to 11,700 years ago and commonly known as the last ice age – developed, said Peter Clark, a paleoclimatologist at Oregon State University ...

In recent years, Americans have gotten used to logging on to a patient portal through their smartphone or computer to have telehealth appointments with their doctors and health care teams, see their prescriptions and lab test results, send messages to their providers, and much more. But a new study suggests that the integration of this technology into many aspects of patient care may have created an unintended barrier to healthcare access for the more than 25 million patients with limited English proficiency. The study finds that the patient portal login page for many hospitals is not accessible ...

Infrared vibrational spectroscopy at BESSY II can be used to create high-resolution maps of molecules inside live cells and cell organelles in native aqueous environment, according to a new study by a team from HZB and Humboldt University in Berlin. Nano-IR spectroscopy with s-SNOM at the IRIS beamline is now suitable for examining tiny biological samples in liquid medium in the nanometre range and generating infrared images of molecular vibrations with nanometre resolution. It is even possible to obtain 3D information. ...

As our hairs go gray and our muscles weaken with age, our immune system also changes. In particular, the stem cells that become blood or immune cells can develop mutations, potentially leading to cancers or other dysfunctions. Researchers at the University of Illinois Chicago have discovered an important cellular mechanism that drives this aging: the lack of a protein called platelet factor 4, whose levels decrease with age, they report in the journal Blood. What’s more, adding this protein to old blood cells reversed these signs of aging, which points to a promising therapeutic target for preventing ...

Palm oil isn’t inherently bad, and olive oil isn’t inherently good, conservation scientists say in an opinion paper publishing October 16 in the Cell Press journal Cell Reports Sustainability. They argue that the vegetable oil industry is haunted by narratives and myths about different types of oil crops, but the reality is much more nuanced. Almost all oils—including soybean, olive, coconut, and sesame oil—are associated with biodiversity and human rights issues in some contexts, depending on crop management and supply chains. The researchers call ...
