Metamaterials are products of engineering wizardry. They are made from everyday polymers, ceramics, and metals. And when constructed precisely at the microscale, in intricate architectures, these ordinary materials can take on extraordinary properties.  With the help of computer simulations, engineers can play with any combination of microstructures to see how certain materials can transform, for instance, into sound-focusing acoustic lenses or lightweight, bulletproof films. But simulations can only take a design so far. To know for sure whether a metamaterial will stand up to expectation, physically testing them is a must. But there’s been no reliable way to push and pull ...

Cerebral edema, the dangerous brain swelling that occurs after traumatic brain injury (TBI), can increase risk of death tenfold and significantly worsen prospects for recovery in brain function.  In extreme cases, surgeons will remove a portion of the skull to relieve pressure, but this has significant risks and is not viable for the vast majority of TBI cases. Physicians have very few tools at their disposal that are effective in treating cerebral edema, which is one of the leading causes of in-hospital deaths, and is associated with long-term neurological disability. New ...

About The Study: The findings of this study suggest that rates of completion for 4,133 diagnostic tests and referrals (colonoscopies, cardiac stress tests, and dermatology referrals) were low for all visit types but worse when ordered during telehealth visits.

Seabirds roam far and wide in the Indian Ocean – so they need ocean-wide protection, new research shows. All other oceans are known to contain “hotspots” where predators including seabirds feast on prey. But the new study – by a team including Exeter, Heriot-Watt and Réunion universities, and ZSL – found no such concentrations in the Indian Ocean. With seabirds facing numerous threats due to human activity, their survival depends on protecting the open ocean. “Efforts are being made to protect key breeding colonies, but until now little was known about where Indian Ocean seabirds ...

Researchers from the University of B.C. and the BC Provincial Toxicology Centre (BCPTC) have developed a more efficient way to find out which new ‘designer drugs’ are circulating in the community. In a study published today in Analytical Chemistry, they showed how high-resolution mass spectrometry can be used to analyze urine samples at scale and uncover molecules from emerging designer drugs that have been missed by conventional testing. The approach can support public health and safety by enabling swift identification of new substances, potentially saving lives and guiding timely clinical responses to drug-related ...

With 3D inkjet printing systems, engineers can fabricate hybrid structures that have soft and rigid components, like robotic grippers that are strong enough to grasp heavy objects but soft enough to interact safely with humans.  These multimaterial 3D printing systems utilize thousands of nozzles to deposit tiny droplets of resin, which are smoothed with a scraper or roller and cured with UV light. But the smoothing process could squish or smear resins that cure slowly, limiting the types of materials that can be used.   Researchers from MIT, the MIT spinout Inkbit, and ETH Zurich have developed a new 3D inkjet printing system that works ...

For a magnet to stick to a fridge door, inside of it several physical effects need to work together perfectly. The magnetic moments of its electrons all point in the same direction, even if no external magnetic field forces them to do so. This happens because of the so-called exchange interaction, a combination of electrostatic repulsion between electrons and quantum mechanical effects of the electron spins, which, in turn, are responsible for the magnetic moments. This is common explanation for the fact that certain materials like ...

A research team, led by Tokyo Medical and Dental University（TMDU）, identifies disease-associated variants in a rare case of RAD50 deficiency/Nijmegen breakage syndrome-like disorder Tokyo, Japan – Many disorders are caused by genetic variants; to make matters worse, the genetic origin of most disorders remains unknown. Now, in a study recently published in the Journal of Clinical Immunology, researchers have shed light on the specific variants responsible for one rare and serious disorder: ‘RAD50 deficiency/Nijmegen breakage syndrome-like ...

In China, there is an old saying: "Don't let your children lose on the starting line." It highlights parents' desire to jumpstart their child's early development. Especially in recent years, parents have become increasingly anxious about their children's education, making it a trend to encourage children to participate in extracurricular activities from an early age. But is participating in extracurricular classes always advantageous for young children? Recently, a study published in the Journal of School Psychology found that extracurricular activities don't always improve a child's skills or behaviour. The ...

University of Virginia School of Medicine public health researchers, together with colleagues at the University of South Carolina, have received a $3.37 million grant from the National Institutes of Health to determine if online behavioral weight-management programs for rural residents can be improved by adding a human touch. Online obesity programs have typically failed to yield the same benefits as in-person programs, the researchers note, so they will test three approaches to add human involvement. More than 600 volunteer participants will be enrolled in a core online 24-week weight-loss ...

Recently, morning omelets and holiday dinners have gotten more expensive. One likely cause is bird flu, outbreaks of which led to the deaths of millions of chickens and turkeys from infection or culling in 2022, according to the U.S. Department of Agriculture, and which still demands rigorous monitoring of wild populations. Now, reporting in Environmental Science & Technology Letters, researchers have developed a method that detected infectious bird flu virus in wetlands frequented by waterfowl. Wild birds represent a significant reservoir of avian influenza ...

From the depths of the seas to snow on mountains and even the air above cities, microplastics are turning up increasingly often. Now, in ACS’ Environmental Science & Technology Letters, researchers have analyzed microplastics in clouds above mountains. They suggest that these tiny particles could play a role in cloud formation and, in turn, affect weather. Microplastics — plastic fragments smaller than five millimeters — originate from a myriad of items used daily, such as clothing, packaging and car tires. As research in the field evolves, scientists are not only detecting microplastics in the atmosphere but also investigating how they may play a role in cloud formation. ...

Considering the molecular subtype of muscle-invasive bladder cancer (MIBC) based on differences in tumor RNA expression can improve the ability of an existing tumor biomarker such as the COXEN score to predict which patients’ tumors are likely to respond to chemotherapy given before surgery. Individual molecular subtypes, however, were not associated with significant differences in patients’ overall survival (OS) or progression-free survival (PFS) times. Those are the conclusions from a secondary analysis of data from the S1314 clinical trial, a large study in patients with MIBC that was conducted by the SWOG Cancer Research Network, a clinical trials group funded by ...

Aldehydes are toxic compounds that are produced in the body by metabolic processes, especially upon alcohol consumption. They are dangerous because they bind to cellular macromolecules such as DNA, RNA, and proteins, and crosslink them.   Crosslinking damage to DNA must be repaired by the cell to prevent premature aging and cancer. However, it was previously unknown whether and how cells sense and resolve crosslinking damage to single-stranded RNA. A team led by Professor Julian Stingele from ...

Every tree species has its story. Unraveling all 73,000 of them is a significant undertaking for science, in no small part because a considerable proportion of tree biodiversity is tropical, rare, remote and subject to the ravages of deforestation. And an estimated 9,200 tree species have yet to be discovered. Even trees well-known to science have mysteries. One is the Seychelles’ endangered coco de mer, or sea coconut palm tree, which is now relegated to parts of two small Indian Ocean islands and in decline. Only some 8,200 individuals remain. What Lodoicea madivica lacks in range it makes ...
