RICHLAND, Wash.—After thousands of years as a highly valuable commodity, silk continues to surprise. Now it may help usher in a whole new direction for microelectronics and computing. While silk protein has been deployed in designer electronics, its use is currently limited in part because silk fibers are a messy tangle of spaghetti-like strands.  Now, a research team led by scientists at the Department of Energy’s Pacific Northwest National Laboratory has tamed the tangle.  They report in the journal ...

NEW YORK, NY (September 18, 2024)—Columbia University will award the 2024 Louisa Gross Horwitz Prize to Scott Emr and Wesley Sundquist for discovering the ESCRT (Endosomal Sorting Complexes Required for Transport) pathway and revealing how it works. ESCRT (pronounced “escort”) complexes deform the cell membrane and bend parts of it away from the cytoplasm, the space that houses all material inside a cell. This unique process plays an essential role in keeping cells healthy by packaging and sorting molecules, removing waste, and regulating important functions such as cell division, neuron remodeling, ...

Images A set of knee exoskeletons, built with commercially available knee braces and drone motors at the University of Michigan, has been shown to help counteract fatigue in lifting and carrying tasks. They helped users maintain better lifting posture even when tired, a key factor in defending against on-the-job injuries, the researchers say.   "Rather than directly bracing the back and giving up on proper lifting form, we strengthen the legs to maintain it," said Robert Gregg, U-M professor of robotics and corresponding author of the study in Science Robotics. "This differs from what's more commonly done in industry."   Already ...

Researchers at the National Institutes of Health (NIH) and their collaborators have identified a protein, known as RNF114, that reverses cataracts, a clouding of the eye’s lens that occurs commonly in people as they age. The study, which was conducted in the 13-lined ground squirrel and rats, may represent a possible surgery-free strategy for managing cataracts, a common cause of vision loss.  The study published in the Journal of Clinical Investigation. “Scientists have long searched for an alternative to cataract surgery, which is effective, but not without risk. Lack of access to cataract surgery is a barrier to care in some ...

Tomorrow’s workplace will be run on mind-boggling amounts of data. To make sense of it all, businesses, developers and individuals will need better artificial intelligence (AI) systems, better trained AI workers and more efficient number-crunching servers. While big tech companies have the resources and expertise to meet these demands, they remain beyond the reach of most small and medium-sized enterprises and individuals. To respond to this need, a Concordia-led international team of researchers has developed a new framework to make complex AI tasks more accessible ...

Anyone who has ever pet a cat or shuffled their feet across the carpet knows that rubbing objects together generates static electricity. But an explanation for this phenomenon has eluded researchers for more than two millennia. Now, Northwestern University scientists have finally uncovered the mechanics at play.  When an object slides, the front and back parts of that object experience different forces, researchers found. This difference in forces causes different electrical charges to build up on the front and back parts of the object. And the difference in electrical charges creates a current, leading to a light zap. The study was published yesterday (Sept. 17) in the journal ...

In a rare and extraordinary discovery, researchers have identified a unique configuration of galaxies that form the most exquisitely aligned gravitational lens found to date. The Carousel Lens is a massive cluster-scale gravitational lens system that will enable researchers to delve deeper into the mysteries of the cosmos, including dark matter and dark energy. “This is an amazingly lucky ‘galactic line-up’ – a chance alignment of multiple galaxies across a line-of-sight spanning most of the observable universe,” said David Schlegel, a co-author of the study and a senior scientist in Berkeley Lab’s Physics Division. "Finding one such alignment is ...

A newly identified wasp species, Chrysonotomyia susbelli, has been discovered in Houston, Texas, marking the 18th new species identified by Rice University’s Scott Egan and his research team since 2014. The discovery, the fourth wasp species found on the university grounds in seven years, reveals the hidden world of parasitoid wasps and the intricate ecosystems that thrive outside our doors. The Chrysonotomyia susbelli is a parasitoid wasp, about 1 millimeter long, that emerges from galls, or tumorlike growths created by the gall wasp Neuroterus bussae found on southern live oak leaves. The galls serve as microhabitats within which larvae feed, develop and pupate. ...

Researchers have achieved a groundbreaking advancement in plant biotechnology by using a magnetofected pollen gene delivery system to genetically transform cucumbers. This cutting-edge method uses DNA-coated magnetic nanoparticles to introduce foreign genes into pollen, producing genetically modified seeds without the need for traditional tissue culture or regeneration steps. This technique significantly streamlines and accelerates crop genetic modification, opening up new avenues to boost agricultural productivity and resilience. Genetic modification in horticultural crops, particularly within the Cucurbitaceae family, is often hindered by complex tissue culture requirements and ...

Some of the greatest discoveries don’t come merely from observations but from thinking. Einstein developed theories about relativity through thought experiments, and Galileo derived insights about gravity through mental simulations. A review published September 18 in the journal Trends in Cognitive Sciences shows that this process of thinking is not exclusive to humans. Artificial intelligence, too, is capable of self-correction and arriving at new conclusions through “learning by thinking.” “There are some recent demonstrations of what looks like learning by thinking in AI, ...

In an opinion article publishing September 18 in the Cell Press journal Trends in Molecular Medicine, physician-scientists argue that with most placentas discarded after birth, placental pathology is underutilized clinically, should be a routine part of obstetric and neonatal care, and also deserves more research attention. “Placentas should not be considered a waste tissue,” says senior author Mana Parast, MD, PhD, professor of pathology at University of California San Diego School of Medicine. ...

Drug overdose mortality has risen faster among adolescents than the general population in recent years, largely due to fentanyl, a potent opioid pain medication. A new study published in JAMA sheds light on trends in nonfatal opioid overdoses in youth – an area that was not as well characterized, but key to formulating prevention strategies to save lives. Researchers from Ann & Robert H. Lurie Children’s Hospital of Chicago and colleagues analyzed data using Emergency Medical Services (EMS) encounters from January 2018 to December 2022. They found that opioid overdoses in youth increased at pandemic onset and remained elevated compared to pre-pandemic levels. The majority ...

About The Study: Prehospital encounters for youth opioid overdoses were increasing prior to the pandemic, increased with the onset, and then stabilized, remaining higher than pre-pandemic levels. Although overall patterns were largely driven by those ages 18 through 24, adolescents ages 12 through 17 were the only subgroup with an increasing number of encounters both before and during the pandemic.

Risk calculators are used to evaluate disease risk for millions of patients, making their accuracy crucial. But when national models are adapted for local populations, they often deteriorate, losing accuracy and interpretability. Investigators from Brigham and Women’s Hospital, a founding member of the Mass General Brigham healthcare system, used advanced machine learning to increase the accuracy of a national cardiovascular risk calculator while preserving its interpretability and original risk associations. Their results showed higher accuracy overall in an electronic health records cohort ...

One of the main targets of Russia’s ongoing attacks on Ukraine is the energy infrastructure. The extent of the destruction is enormous. “One year after the start of the war in February 2022, 76 percent of thermal power plants had been destroyed; now the figure is 95 percent,” says Ukrainian scientist Iryna Doronina. “And all the large hydroelectric power plants have also failed.” The breaching of the Kakhovka dam proved to be particularly devastating. The huge outflow of water – the reservoir ...
