Defects often limit the performance of devices such as light-emitting diodes (LEDs). The mechanisms by which defects annihilate charge carriers are well understood in materials that emit light at red or green wavelengths, but an explanation has been lacking for such loss in shorter-wavelength (blue or ultraviolet) emitters. Researchers in…
Geoscientists have long thought that water — along with shallow magma stored in Earth’s crust — drives volcanoes to erupt. Now, thanks to newly developed research tools at Cornell, scientists have learned that gaseous carbon dioxide can trigger explosive eruptions. A new model suggests that basaltic volcanoes, typically located on…
Researchers at Kobe University discovered an entirely new and unexpected mechanism by which the immune system can get rid of cells lacking molecules that identify them as part of the self in mice. The finding, published in PNAS, has possible implications for cancer treatment. The immune system comprises many types…
Social learning is typically thought to be most beneficial when the environments in which individuals live change quite slowly – they can safely learn tried and tested information from one another and it does not go out of date quickly. Innovating brand-new information, on the other hand, is thought to…

The new technology allows for the first time the placement of optical elements or electronics on live cells with…
There is more to a harmful algal bloom than the green stuff in water that meets the eye — specifically, a changing hazard level of toxins produced by the microbes that make up the scummy mess. A new study analyzing toxins produced by Microcystis, the main type of cyanobacteria that…
A new study explores the relationship between a canine’s facial appearance and how expressive they appear to be when communicating with their human companions. The domestication of canines and their co-evolution with humans has fostered an incredibly unique relationship with these animals. Over time, our four-legged friends have adapted well…
An antibody in single-chain fragment variable (scFv) format that binds to the powerful opioid carfentanil was shown to reverse signs of carfentanil overdose in preclinical tests conducted by scientists at Scripps Research. Carfentanil is a variant of the synthetic opioid fentanyl, and about 100 times as potent as its chemical…
CNN — An alleged informant for Russia has been detained in connection to a plot to assassinate Ukrainian President Volodymyr Zelensky, the Ukrainian Security Service (SBU) said Monday. The detained woman has not been named publicly but is from the southern Ukrainian region of Mykolaiv, according to a statement from…
Heliconius butterflies are capable of spatial learning, scientists have discovered. The results provide the first experimental evidence of spatial learning in any butterfly or moth species. The findings, published today in Current Biology, also suggest Heliconius butterflies may be able to learn spatial information at large scales, consistent with the…
Researchers from the UCLA Samueli School of Engineering have unveiled an artificial intelligence-based model for computational imaging and microscopy without training with experimental objects or real data. In a recent paper published in Nature Machine Intelligence, UCLA’s Volgenau Professor for Engineering Innovation Aydogan Ozcan and his research team introduced a…
The Covid-19 pandemic created a global increase in domestic violence against women. Now, an MIT-led experiment designed with that fact in mind shows that some forms of social media can increase awareness among women about where to find resources and support for addressing domestic violence. In the randomized experiment, set…
As Canadian wildfire smoke continues to impact large swaths of the United States, resulting in poor air quality and negative health outcomes for millions of Americans, more people than ever are feeling the effects of longer fire seasons and a changing climate. Now, researchers at Washington University in St. Louis…
Researchers from the National Institutes of Natural Sciences and Nagoya City University have achieved a significant breakthrough by elucidating the structure of amyloid β (Aβ) bound to glycolipids on the surface of nerve cells. This finding shed light on the critical role of abnormal Aβ fibril formation, a major contributor…
As we start to edge out of winter, improving our diet and boosting our exercise start to appear on our agenda. But, when it comes to encouraging a healthier lifestyle, it may surprise you that artificial intelligence could be your best friend. Now, in a first systematic review and meta-analysis…
Researchers at Tohoku University and Massachusetts Institute of Technology (MIT) have unveiled a representative effect of the anomalous dynamics at play when an electric current is applied to a new class of magnetic materials called non-collinear antiferromagnets. Their findings were published in the journal Nature Materials on August 3, 2023.…
“Your presence means the world to me” may sound like a wedding invitation cliché, but an Osaka Metropolitan University study has shown that the presence of others while working does generate a state of relaxation and positive brain activity. In psychiatry, occupational therapy encompasses not only the individual-therapist relationship but…
An international collaboration between researchers at the RIKEN Center for Brain Science (CBS) in Japan, the University of Tokyo, and University College London has demonstrated that self-organization of neurons as they “learn” follows a mathematical theory called the free energy principle. The principle accurately predicted how real neural networks spontaneously…
Today in the U.S., a child with risk factors for heart disease (high blood pressure, overweight, etc.) can wait close to a year to see a cardiologist because of high demand and limited resources. This is precious time that could be spent managing their conditions to help them avoid having…
Scientists have worked out how one unusual species of trilobite — an ancient, sea-dwelling relative of spiders and lobsters — was able to defend itself against predators and survive a bumpy ride as Earth’s oxygen levels fluctuated. Source link
ells or B lymphocytes are an important part of the body’s immune system. When healthy B cells are infected with the Epstein-Barr virus (EBV), they undergo growth transformation, a process that immortalizes B cells, leading to their uncontrolled proliferation. The induction of immortalized B cells is the first step in…
A Roman road network that spanned Devon and Cornwall and connected significant settlements with military forts across the two counties as well as wider Britannia has been discovered for the first time. Archaeologists at the University of Exeter have used laser scans collected as part of the Environment Agency’s National…
Heart rate (HR) estimation is an essential component of health monitoring, and provides useful insights regarding the physiological and emotional state of humans. In the past decade or so, researchers have explored newer approaches for contactless HR estimation, primarily to overcome the discomfort or dermatitis associated with conventional methods that…
New research shows that a person’s own behavior is the primary driver of how they treat others during brief, zero-sum-game competitions. Generous people tend to reward generous behavior and selfish individuals often punish generosity and reward selfishness — even when it costs them personally. The study found that an individual’s…
The spectacled caiman, a species native to Central and South America, has been established in Florida since the 1970s. The pet trade and crocodilian farming industries, escapes and deliberate releases made it possible for caimans to invade the Florida Everglades. They pose a threat to native wildlife occupying the same…
