Scientists are understanding more about natural killer (NK) cells, which are your allies when it comes to fighting infections and cancer.

New research shows table corals can regenerate coral reef habitats on the Great Barrier Reef decades faster than any other coral type. The research suggests overall reef recovery would slow considerably if table corals declined or disappeared on the Great Barrier Reef.

Researchers have developed a technique that could allow deep brain stimulation devices to sense activity in the brain and adjust stimulation accordingly.

Researchers have developed a robotic mechanism for mushroom picking and trimming and demonstrated its effectiveness for the automated harvesting of button mushrooms.

Simulators have long been used for training surgeons and surgical teams, but traditional simulator platforms typically have a built-in limitation: they often simulate one or a limited number of conditions that require performance of isolated tasks, such as placing an intravenous catheter, instead of simulating and providing opportunities for feedback on the performance of multiple interventions...

Recent failed clinical trials of a drug designed to clear the mutant Huntingtin protein that causes Huntington's disease (HD) heightens the need for new approaches for the devastating, incurable, progressive neurodegenerative genetic disorder. Scientists have found that the targeting the protein called FK506-binding protein 51 or FKBP51 promotes the clearing of those toxic proteins via autophagy,...

An unexpected discovery suggests that the first humans may have arrived in North America more than 30,000 years ago - nearly 20,000 years earlier than originally thought.

Researchers have developed a novel approach to mitigating electromigration in nanoscale electronic interconnects that are ubiquitous in state-of-the-art integrated circuits. This was achieved by coating copper metal interconnects with hexagonal boron nitride (hBN), an atomically-thin insulating two-dimensional (2D) material that shares a similar structure as the 'wonder material' graphene.

Observational studies have suggested that increased vitamin D levels may protect against COVID-19. However, these studies were inconclusive and possibly subject to confounding. A new study suggests that genetic evidence does not support vitamin D as a protective measure against COVID-19.

A new study analyzing the association between an individual's genetics (genotype) and their observable characteristics resulting from the interaction of genetics and the environment (phenotype), contributes new knowledge to the understanding of human complex traits and diseases.

Researchers experimentally show that quantum resources have an advantage over classical -- even in the NISQ era.

Many organisms in need of conservation are still unknown or lumped in with similar species, which potentially interferes with conservation efforts. Researchers present a new 'return-on-investment' approach to best direct efforts to identify new species before they are lost.

Evidence of sleep-dependent low-frequency (less than 0.1 Hz) global brain activity in the clearance of Alzheimer's disease-related toxin buildup is presented in new research. This neuronal activity was more strongly linked with cerebrospinal fluid flow in healthy controls than higher risk groups and patients, and the findings could serve as a potential imaging marker for clinicians in evaluating...

New research describes a new metamaterial system that acts as its own sensor, recording and relaying important information about the pressure and stresses on its structure. The so-called 'self-aware metamaterial' generates its own power and can be used for a wide array of sensing and monitoring applications.

Researchers have discovered a gene, OTUD7A, that impacts the development of Ewing sarcoma, a bone cancer that occurs mainly in children. They have also identified a compound that shows potential to block OTUD7A protein activity. Critical relationships between proteins contribute to the development of cancers such as Ewing sarcoma. So, it was a seminal discovery when the researchers found that...

A new analysis of adults aged 80 years and older shows that a healthier lifestyle is associated with a lower risk of cognitive impairment, and that this link does not depend on whether a person carries a particular form of the gene APOE.

Malaria, a disease caused mainly by the parasites Plasmodium falciparum and Plasmodium vivax, is associated with over 400,000 deaths each year. Previously, the spleen was assumed to mostly play a role in parasite destruction, as it eliminates malaria parasites after antimalarial treatment. A new study suggests that in chronic P. vivax infections, malaria parasites survive and replicate via a...

A clinical trial examining the efficacy of two devices to monitor and detect atrial fibrillation (AF), or an irregular heartbeat, in ischemic stroke patients -- one an implantable device that monitors over 12 months, the other an external device that monitors over a 30-day period -- found the implantable device is more than three times more effective in detecting AF.

Researchers have discovered a new mechanism in magnetic compounds that couples multiple topological bands. The coupling can significantly enhance the effects of quantum phenomena.

Aerosol reductions that would take place as countries meet climate goals could contribute to global cooling and prevent more than one million annual premature deaths over a decade, according to a new study.

Researchers have developed an artificial-intelligence-powered tool to predict and warn of a deadly phenomenon in burning buildings known as flashover, when flammable materials in a room ignite almost simultaneously, producing a potentially ferocious blaze. The tool's predictions are based on temperature data from a building's heat detectors, and, remarkably, it is designed to operate even after...

Scientists have revealed a potential mechanism for how traumatic brain injury leads to neurodegenerative diseases.

Scientists working to unlock the mysteries Australia's deadly stonefish have made a discovery which could change how sting victims are treated in the future.

Researchers have conducted the first precise and comprehensive measurements of sea level rises in the Baltic Sea and the North Sea. A new method now makes it possible to determine sea level changes with millimeter accuracy even in coastal areas and in case of sea ice coverage. This is of vital importance for planning protective measures.
