WASHINGTON, Nov. 4, 2025 — LEDs, or light-emitting diodes, are essential components in near-eye displays like virtual reality and augmented reality headsets and smart glasses, along with electronics like cameras and medical equipment. Conventional LEDs use direct current power, which requires two contacts, like the positive and negative contacts to connect a battery. As device form factors continue to shrink, fabricating nano-LEDs requires each of the hundreds of microscopic components to touch both contacts, which presents a complicated alignment problem for device manufacturers. In Applied Physics Letters, ...

About The Study: The findings of this cohort study suggest that facility-based colorectal cancer screening among adults ages 45 to 49 increased nearly 10-fold following U.S. Preventive Services Task Force (USPSTF) guideline changes, far exceeding growth among those ages 50 to 75. This rapid adoption highlights early implementation by practitioners and patients. Although screening rates among adults ages 50 to 75 increased during the study period, the accelerated growth among those ages 45 to 49 reflected guideline ...

A hidden structure inside the cell is rewriting how scientists understand leukemia. Beneath the microscope, what looked like disorder turned out to follow a simple physical rule – one that connects several major mutations behind the disease.   In new research from Baylor College of Medicine published in Cell, scientists reveal that different genetic drivers of leukemia use the same secret compartments inside the cell nucleus to keep cancer growing. The finding points to a shared physical target that could inspire new kinds of treatments.   The ...

CAMBRIDGE, MA - MIT engineers have developed a flexible drug-delivery patch that can be placed on the heart after a heart attack to help promote healing and regeneration of cardiac tissue. The new patch is designed to carry several different drugs that can be released at different times, on a pre-programmed schedule. In a study of rats, the researchers showed that this treatment reduced the amount of damaged heart tissue by 50 percent and significantly improved cardiac function. If approved for use in humans, ...

A new study by investigators from Mass General Brigham shows that patients with traumatic spinal cord injuries (TSCI) are at a higher risk of developing a myriad of chronic health problems, regardless of age, location of the injury and prior health status. Their results are published in JAMA Network Open. “The journey doesn't end when patients with traumatic spinal cord injuries leave the hospital or rehab,” said corresponding author Saef Izzy, MD, FAAN, FNCS, a neurologist in the Department of Neurology at Mass General Brigham. “Programs should be implemented to identify patients at risk so that ...

Temperature is a key physiological factor that determines the speed of immune reactions. While this may seem obvious, it has remained largely unexplored at the single-cell level—until now. Stefan Wieser from the Institute of Zoology at the University of Innsbruck and his colleagues report in Developmental Cell that the motor protein Myosin II regulates the temperature sensitivity of immune cells and drives the acceleration of immune responses at elevated body temperature. Wieser first noticed that temperature affects the movement of immune ...

Contrails form when hot exhaust gas from an aircraft’s engine mixes with the cold air at an altitude of about 10 kilometres. In dry air, most contrails dissipate quickly. In cold, humid air, however, they can persist for several hours and develop into extensive cirrus clouds. Cirrus clouds are high, thin ice clouds at an altitude of about 5 to 12 kilometres, which often appear as delicate, wispy veils in the sky. Until now, researchers had assumed that long-lived contrails form mainly in clear skies, where they exert their warming effect. However, the new study shows that they mostly form within existing natural ...

ukuoka, Japan—Researchers at Kyushu University have designed a class of molecules whose ability to amplify light energy can be actively controlled by simply applying pressure. The findings, published in the journal Chemical Science, may open new possibilities for highly efficient energy conversion devices and advanced medical therapies. The study is centered on a physical process called singlet fission (SF). SF is a mechanism where, when a molecule is struck by a single high-energy photon, it splits that energy to create two lower-energy excited states instead of just one. In effect, it acts like an ...

Bullying and lack of psychological support from managers top the list of workplace factors that can lead to serious mental health problems, according to a new investigation of work-related anxiety in four countries. The study shows that 11.2 per cent of people in Norway have reduced capacity for work due to work-related anxiety. “Work-related anxiety is not just stress. Anxiety is the worry that follows you home, steals your sleep, and meets you again the next day at work,” said Leon De Beer, an associate professor at the Norwegian ...

Research on human brain organoids (HBOs) is directly challenging how biobanks and biomedical institutes recruit volunteers. That is what a new study by Japanese researchers in Frontiers in Genetics concludes after finding that the Japanese public overwhelmingly rejects the common practice of broad consent when their donated cells could be used to create HBOs. This attitude jeopardizes recruitment and calls for an alternative form of consent that follows the project-specific consent model. Researchers can culture ...

The road to genocide doesn’t begin with bullets and mass graves, but with more subtle violations. Declining workers’ rights or compromises on the right to a fair trial may come first. Brutality by law enforcement and prison guards becomes widespread. The judiciary loses its independence from the executive branch. And then, more serious signs follow: Freedom of speech is restricted for a specific group of people, and then their right to assemble in public places. Members of this group may find themselves increasingly imprisoned for their beliefs, ...

Different species of spiders produce different silks that serve different purposes, from floating on air to cradling eggs. The triangle weaver spider, Hyptiotes cavatus, weaves and holds a three-sided web under tension, which it releases the moment prey flies into the web, quickly tangling the prey in the spring-loaded threads. Thus, the web can move much faster than any muscle in the spider’s body, illustrating how silk can amplify a spider’s abilities. Jessica Garb and colleagues sequenced the genome of ...

An analysis of brain scans from 572 people reveals that activity in brain regions linked to reward and social processing can predict how effective messages will be. Christin Scholz, Hang-Yee Chan, Emily Falk, and colleagues pooled data from 16 functional MRI studies to explore how the human brain responds to persuasive messages across various contexts, including public health campaigns, crowdfunding sites, movie trailers, and YouTube videos. Across these diverse settings, the researchers found that effective messages activated brain regions involved in anticipating and receiving rewards, ...

Australians who speak a language other than English at home were more likely ...

Ribonucleic acid (RNA) is one of life’s most versatile molecules, with roles going far beyond being a messenger of genetic code, as it is fundamentally involved in gene regulation, processing, and maintenance across all living systems. This versatility is deeply tied to RNA’s ability to adopt complex three-dimensional shapes, known as secondary and tertiary structures. With the global rise of RNA-based therapeutics, understanding and precisely predicting secondary and tertiary structures is essential to fully harness the RNA’s ...

Closing the skull safely and securely after surgery remains one of neurosurgery’s biggest challenges. Traditional fixation systems made from titanium or semi-absorbable polymers can interfere with brain imaging, degrade unevenly, or remain in the body long after healing. These drawbacks can slow down recovery, cause discomfort, and increase the risk of complications. To address these issues, a team led by Dr. Siyi Wanggou and Professor Xuejun Li from the Department of Neurosurgery, Xiangya Hospital, Central South University, China, collaborated with MedArt Technology Co., Ltd., China, to develop a fully degradable cranial flap fixation system made from high-purity poly-L-lactic ...
