When the wireless data runs dry

To train artificial intelligence (AI) models, researchers need good data and lots of it. However, most real-world data has already been used, leading scientists to generate synthetic data. While the generated data helps solve the issue of quantity, it may not always have good quality, and assessing its quality has been overlooked. Wei Gao, associate professor of electrical and computer engineering at the University of Pittsburgh Swanson School of Engineering, has collaborated with researchers ...

Inquiry into the history of science shows an early “inherence” bias

Early scientific theories—such as those explaining basic phenomena like gravity, burning, and the movement of molecules in water—centered on presumed inherent properties rather than external factors, thereby misleading famous philosophers and scientists, from Aristotle to Scottish botanist Robert Brown, in their theorizing. A new study by a team of psychology researchers has now found that this tendency is in fact common in the history of science. Moreover, through a series of experiments and surveys, the paper’s authors conclude these misfires were likely driven by cognitive constraints, among scientists and non-scientists alike, that have acted ...

Why do people believe lies?

Detecting lies involves processing social information. How do people process social information and evaluate honesty? And do people process this information differently when it comes from a friend versus a stranger? Yingjie Liu, from North China University of Science and Technology, led a study to explore how people assess different kinds of information from friends or strangers. As reported in their JNeurosci paper, the researchers used a neuroimaging technique on 66 healthy volunteers as they communicated on computer screens while sitting across from each other. When the information being communicated led to benefits for pairs, this was considered a “gain” and likewise ...

A new perspective in bone metabolism: Targeting the lysosome–iron–mitochondria axis for osteoclast regulation

Background: Osteoporosis is a common skeletal disorder characterized by excessive bone loss, leading to increased fragility and an increased risk of fractures. Osteoclasts, the bone-resorbing cells, are widely recognized as central players in this process. Osteoclast-mediated bone resorption relies critically on two organelles: lysosomes, which degrade the bone matrix, and mitochondria, which provide the necessary energy. Iron, acting as a key connector between lysosomes and mitochondria, has emerged as an essential regulator of osteoclast activity. ...

Few military spouses use formal support services during, after deployment

CHAMPAIGN, Ill. — Cycles of deployment and reintegration can be stressful, disruptive times for military spouses and their families. Although the Department of Defense and its military communities offer a number of formal resources to help military spouses cope during these challenging periods, very few of those who participated in a recent study said they actually used them. Only 16.5% of those in the study had participated in a formal reintegration program after their partners returned from deployment. The findings are concerning and contribute to a growing body of research indicating that thousands of military spouses may not be receiving the support they need ...

Rational high entropy doping strategy via modular in-situ/post solvothermal doping integration for microwave absorption

Materials scientists have long pursued advanced microwave absorption materials to address growing electromagnetic pollution challenges in both military stealth and civilian shielding applications. Transition metal dichalcogenides, particularly MoS2, have emerged as promising candidates due to their unique 2D layered structures and tunable electronic properties. However, conventional single-element doping strategies have shown limited effectiveness in achieving broadband absorption, while multi-element high-entropy doping in MoS2 systems remains ...

Recent advances in exciton-polariton in perovskite

Perovskites, a class of materials known for their stellar performance in solar cells, are now making waves in the world of advanced optics. These versatile semiconductors can capture and emit light in ways that traditional materials like silicon cannot, offering a cheaper and simpler way to create cutting-edge technologies. This review explores a fascinating phenomenon called exciton-polaritons, hybrid particles formed when light and matter merge so strongly that they act as one. This merging, or “strong coupling,” happens when light bounces inside tiny cavities, interacting intensely ...

Country of birth, race, ethnicity, and prenatal depression

About The Study: Across racial and ethnic groups, prenatal depression diagnosis and moderate to severe depression symptoms varied by maternal nativity in this cross-sectional study. The observed advantage among non–U.S.-born individuals across other maternal and neonatal outcomes may not uniformly apply to prenatal mental health conditions when race and ethnicity are considered. Future research should explore sociocultural factors that may influence this association. Corresponding Author: To contact the corresponding author, ...

You’ve never seen corn like this before

Plant stem cells are crucial for the world’s food supply, animal feed, and fuel production. They lay the foundation for how plants grow. Yet, much about these mysterious building blocks remains unknown. Previous analyses have failed to locate many of the important genes that regulate how these cells function. Now, for the first time, Cold Spring Harbor Laboratory (CSHL) plant biologists have mapped two known stem cell regulators across thousands of maize and Arabidopsis shoot cells. Their research also uncovered new stem cell regulators in both species and linked some to size variations in maize. This method for recovering rare stem cells could be used across the plant kingdom. ...

‘Preventable deaths will continue’ without action to make NHS more accessible for autistic people, say experts

Life-saving opportunities to prevent suicide among autistic people are being missed because systemic barriers make it difficult for them to access NHS support during times of mental health crisis, according to new research. Autistic people experience poorer mental and physical health and live shorter lives than the general population. They are significantly more likely than non-autistic people to die by suicide. Recent estimates suggest that one in three autistic people has experienced suicidal ideation and nearly one in four has attempted suicide. In a study ...

Could we use eye drops instead of reading glasses as we age?

Copenhagen, Denmark: Everybody develops presbyopia as they age – a difficulty in focusing on near objects and text – and often have to resort to reading glasses. However, the solution might be as simple as using special eye drops two or three times a day. A retrospective study of 766 patients presented today (Sunday) at the 43rd Congress of the European Society of Cataract and Refractive Surgeons (ESCRS) [1], found that the majority could read an extra two, three or more lines on the eye chart used for testing near visual acuity (the Jaeger chart) after using specially formulated ...

New hurdle seen to prostate screening: primary-care docs

Although Black men die of prostate cancer at twice the rate of the rest of U.S. males, this fact often is not known or considered during appointments with their primary-care clinicians to discuss a common screening test. The new qualitative study published this week in JAMA Network Open showed that Black men often view their primary-care providers as the gatekeepers to receiving a prostate specific antigen (PSA) test, which is the first step to screening for prostate cancer. “There is an often-used phrase, ‘Prostate cancer is a cancer one dies with; it’s not a disease you die from,’” ...

Cheese fungi help unlock secrets of evolution

Many scientific discoveries are serendipitous—the result of chance. Seeing evolution in action in a cheese cave turned out to be exactly that for Benjamin Wolfe, associate professor of biology, and his colleagues. Back in 2016, Wolfe convinced his former post-doc advisor to drive with him to Jasper Hill Farm in Vermont to get samples of a special cheese called Bayley Hazen Blue, a ruse for her boyfriend to propose marriage at the spot where they first met. Wolfe ended up keeping that cheese in the freezer in his lab. “I’m notorious for not throwing samples away just in case we might ...

Rented e-bicycles more dangerous than e-scooters in cities

E-scooters have often been identified as more dangerous than e-bikes, but that picture changes when they are compared on equal terms. A recently published study from Chalmers University of Technology, Sweden, shows in fact that the crash risk is eight times higher for e-bikes than for e-scooters, calculated based on the trip distance with rental vehicles in cities. This surprising result provides a better basis for cities to make decisions on how much to facilitate different types of micromobility. E-scooters have ...

In-situ molecular passivation enables pure-blue perovskite LEDs via vacuum thermal evaporation

Researchers report an in-situ passivation strategy for pure-blue perovskite light-emitting diodes (PeLEDs), promising for next-generation displays, fabricated by vacuum thermal evaporation. Co-evaporating a phenanthroline ligand (BUPH1) with perovskite precursors coordinates Pb(II) and suppresses halide-vacancy defects, reducing non-radiative losses and spectral drift. Their work is published in the journal Industrial Chemistry & Materials on August 25. Metal halide perovskites are rapidly emerging as candidates for the next generation of displays thanks to their narrow emission linewidths, ...
