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.
News raises optimism in No 10 for unlocking despite warnings from scientists over third waveCoronavirus – latest updatesSee all our coronavirus coverageThe UK has reported no deaths from Covid in a day, for the first time in 10 months, raising optimism in Downing Street that England could forge ahead with the final stage of the roadmap despite scientists warning that extra restrictions might be...
A college education is estimated to add $1 million to a person's lifetime earning potential, but for some students the path to earning one is riddled with obstacles. That journey is even more difficult for students who have been in the foster care system or experienced homelessness, according to a new study from the University of Georgia.
Siberian jays are group living birds within the corvid family that employ a wide repertoire of calls to warn each other of predators. Sporadically, however, birds use one of these calls to trick their neighboring conspecifics and gain access to their food. Researchers from the universities of Konstanz (Germany), Wageningen (Netherlands), and Zurich (Switzerland) have now examined how Siberian jays...
The discovery of graphene, a 2D layered form of carbon, once caused a paradigm shift in science and technology like no other. As this wonder material drew attention from material scientists around the world, it spurred research on other materials that were structurally similar, such as "van der Waals materials," which comprise strongly-bonded 2D atomic layers that are held together by weak...
In the early days of COVID-19 vaccine development, a new social media platform provided a place for like-minded people to discuss vaccines, share misinformation and speculate about the motivations for its development. A new study from the University of Kansas shows people flocked to Parler to discuss the vaccines in an echo chamber-type environment, and those conversations can shed light about how...
While the term "supergene" may bring to mind the genetic hocus-pocus of Peter Parker's transformation into Spiderman, supergenes are actually fairly common phenomena in the realm of biology. A supergene refers to a genomic region containing multiple genes or genetic elements that are tightly linked, allowing genetic variants across the region to be co-inherited. Supergenes may arise when there is...
An interdisciplinary research team from TU Dresden at the Chair of Network Dynamics headed by Prof. Marc Timme has studied people's motivation to use "shared mobility" offers.
Quantum computing and quantum sensing have the potential to be vastly more powerful than their classical counterparts. Not only could a fully realized quantum computer take just seconds to solve equations that would take a classical computer thousands of years, but it could have incalculable impacts on areas ranging from biomedical imaging to autonomous driving.
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.
From the biggest bridges to the smallest medical implants, sensors are everywhere, and for good reason: The ability to sense and monitor changes before they become problems can be both cost-saving and life-saving.
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 from the University of California San Diego.
The electronic structure of metallic materials determines the behavior of electron transport. Magnetic Weyl semimetals have a unique topological electronic structure—the electron's motion is dynamically linked to its spin. These Weyl semimetals have come to be the most exciting quantum materials that allow for dissipationless transport, low power operation, and exotic topological fields that can...
Since the introduction on the market in 1995 of Doxil, pegylated liposomal doxorubicin, liposomes have become one of the most clinically established drug delivery systems in nanomedicine. Among different liposomal formulations, cationic liposomes have attracted great attention because of their capacity to bind negatively charged nucleic acids to perform as non-viral gene delivery tools, and due to...
