For the study, published in Lancet Healthy Longevity, researchers looked at rates of Covid-19 infections between October and February among more than 2,000 care home residents and staff, comparing those who had evidence of a previous infection up to 10 months earlier, as determined by antibody testing, with those who had not been previously infected.
Researchers at Washington University School of Medicine in St. Louis have discovered that the immune cells that protect the brain and spinal cord come primarily from the skull. The finding opens up the possibility of developing therapies to target such cells as a way to prevent or treat brain conditions.
A new West Health/Gallup survey finds nearly all Democrats (97%) and the majority of Republicans (61%) support empowering the federal government to negotiate lower prices of brand-name prescription drugs covered by Medicare.
New research shows that diet, including fish oil supplements, can alter not only the breast microbiome, but also breast cancer tumors. The study appears online in Cancer Research, a journal of the American Association for Cancer Research.
Sea ice thickness is inferred by measuring the height of the ice above the water, and this measurement is distorted by snow weighing the ice floe down. Scientists adjust for this using a map of snow depth in the Arctic that is decades out of date. In the new study, researchers swapped this map for the results of a new computer model designed to estimate snow depth as it varies year to year.
Dogs may have earned the title "man's best friend" because of how good they are at interacting with people. Those social skills may be present shortly after birth rather than learned, a new study by University of Arizona researchers suggests.
A study of two methods for reconstructing ancient temperatures has given climate researchers a better understanding of just how cold it was in Antarctica during the last ice age around 20,000 years ago.
The impact of deploying Artificial Intelligence (AI) for radiation cancer therapy in a real-world clinical setting has been tested by Princess Margaret researchers in a unique study involving physicians and their patients.
A team of scientists led by Nanyang Technological University (NTU Singapore) and Rice University in the US, has uncovered the key to the outstanding toughness of hexagonal boron nitride (h-BN). h-BN can withstand ten times the amount of force that graphene can, which is known as one of the toughest materials on Earth.
How mangrove roots interact with water flow is believed to be a key element in mitigating coastal erosion. Researchers are the first to quantify the optimal mangrove root hydrodynamic with a predictive model, which provides insight into the sediment transport and erosion processes that govern the evolution of the shapes of shorelines. Results can provide useful guidance for coastal managers restoring estuarine mangrove forests or planting mangroves as part of living shoreline stabilization.
Nearly three-quarters of breast cancer patients (73%) report using at least one type of complementary medicine after cancer diagnosis, while oncologists believe that less than half (43%) of patients are using these approaches during cancer care. These and other findings from a national survey of oncologists and breast cancer patients were released in conjunction with the 2021 ASCO Annual Meeting. The study found that doctors report discussing integrative health with only about half of patients, leading... Читать дальше...
A highly-detailed VLA image indicates that the jets of material propelled outward by young stars much more massive than the Sun may be very different from those ejected by less-massive young stars.
A dash of milk could make all the difference to a healthy heart as new research from the University of South Australia finds that people who regularly consume milk have a lower risk of heart disease.
Disruptions from sea-level rise and coastal flooding events have significant indirect impacts on urban traffic networks and road safety.
A research team led by Osaka University precisely set the number of layers in multilayer graphene nanoribbons, controlling the semiconducting and metallic properties of field effect transistors and establishing a design guideline for the practical applications of graphene devices.
An international team of researchers, led by UC Davis Health, developed a new therapeutic approach to treating psoriatic arthritis, a chronic inflammatory disease affecting the joints.
Seismic waves generated by earthquakes travel through Earth's solid iron inner core faster in the direction of the rotation axis than along the equator. UC Berkeley scientists created a core growth model to explain this. To fit seismic data, the model predicts that asymmetric growth of the core leads to crystal movement that preferentially aligns iron-nickel crystals north-south. The model implies that the core is only 0.5-1.5 billion years old, a fraction of Earth's age.
A recent study by a team of researchers led by Yale-NUS researcher Dr. Vinod Kumar Saranathan has discovered a novel way to manufacture single gyroid photonic crystals to work in the visible light spectrum, based on the self-assembly mechanism found in blue-winged leafbirds.
College students who engaged in four or more high-impact practices such as study abroad or internships have a 70% chance of either enrolling in graduate school or finding a full-time job after graduating with a bachelor's degree, finds a new University at Buffalo study. These practices - such as study abroad, internships, undergraduate research, community service, first-year seminars and capstone courses - have the greatest influence on college success, regardless of student or family background.
Controlling coherent interaction between optical fields and quantum systems in scalable, integrated platforms is essential for quantum technologies. A German-British research team has developed an on-chip hollow-core light cage that could provide a platform for quantum-storage and quantum-nonlinear applications. Showing stable non-degrading performance and extreme versatility, the laterally accessible light cage could be a compelling candidate for all-on-chip, integrable, low-cost, vapor-based photon delay.
The system offers an economical way to source essential battery material.
Making quantum networks a reality relies crucially on building efficient optical fiber-based quantum light sources. Here, scientists in Germany present an advanced manufacturing approach to accomplish this task. Femtosecond 3D printing is used to create complex micrometer-sized optics to both enhance the single-photon extraction efficiency of semiconductor quantum dots and couple their emission into single-mode optical fibers. This compact on-chip solution enables high coupling efficiency into a... Читать дальше...
Scientists at the Centro Nacional de Investigaciones Cardiovasculares (CNIC), have identified Meis transcription factors as essential biomolecules for the formation and antero-posterior patterning of the limbs during embryonic development.
Regular strength and impact-type training may decrease or even prevent age-related bone deterioration in men, new research at the University of Jyväskylä, Finland, shows.
Autism spectrum has a particular impact on social interaction. Bilingual families with an autistic child often tend to forego the use of one of the home languages, so as not to further complicate the development of their child's communicative skills. A team led by UNIGE has shown that bilingualism allows autistic children to partially compensate for deficits in theory of mind and executive functions, which are at the root of many of their challenges.
