Researchers in the materials department in UC Santa Barbara's College of Engineering have uncovered a major cause of limitations to efficiency in a new generation of solar cells.
A study by University of Guam researchers has found that shade can mitigate the effects of heat stress on corals. The study, which was funded by the university's National Science Foundation EPSCoR grant, was published in February in the peer-reviewed Marine Biology Research journal.
Lightning bolts break apart nitrogen and oxygen molecules in the atmosphere and create reactive chemicals that affect greenhouse gases. Now, a team of atmospheric chemists and lightning scientists have found that lightning bolts and, surprisingly, subvisible discharges that cannot be seen by cameras or the naked eye produce extreme amounts of the hydroxyl radical -- OH -- and hydroperoxyl radical...
Researchers at Karolinska Institutet and the Public Health Agency of Sweden have studied newborn babies whose mothers tested positive for SARS-CoV-2 during pregnancy or childbirth. The results show that although babies born of test-positive mothers are more likely to be born early, extremely few were infected with COVID-19. The study, which is published in the esteemed journal JAMA, supports the...
Largest study of its kind reveals the way relative brain size of mammals changed over the last 150 million years
Mantis shrimp pack one of the most powerful punches on the planet, splitting water with their explosive blows, but when do their larvae begin letting fly with their ballistic appendages and how fast? The 4.2mm long larvae begin flicking their limbs as early as 9 days after hatching, around when they begin feeding, letting lose accelerations of 22 million deg/s2 and moving at ~0.385m/s, 5-10 times...
Hispanic Americans have died of COVID-19 at a disproportionately high rate compared to whites because of workplace exposure to the virus, a new study suggests.
A collaboration between experts and a Danish-based, global reaching patient organization has resulted in a groundbreaking medical publication, where guidelines are being presented on how to manage patients with unexplained low blood sugar.
Scientists have recreated the reaction by which carbon isotopes made their way into different organic compounds, challenging the notion that organic compounds, such as amino acids, were formed by isotopically enriched substrates. Their discovery suggests that the building blocks of life in meteorites were derived from widely available substrates in the early solar system.
Melting of the Arctic ice sheets caused rapid methane release from the ocean floor during the last two deglaciations, according to a new study in Geology. A similar release is likely to happen today, and should be included in climate models, say the scientists.
A research group working at Uppsala University has succeeded in studying 'translation factors' - important components of a cell's protein synthesis machinery - that are several billion years old. By studying these ancient 'resurrected' factors, the researchers were able to establish that they had much broader specificities than their present-day, more specialised counterparts.
New research published in the American Journal of Emergency Medicine found that in the State of Florida, and also at the local level in Miami-Dade County, higher stringency efforts during the first two months of the pandemic kept overall transmission numbers low.
The researchers identified troubling disparities along race, income and education lines.
Scientists have been able to track how a multi-drug resistant organism is able to evolve and spread widely among cystic fibrosis patients - showing that it can evolve rapidly within an individual during chronic infection. The researchers say their findings highlight the need to treat patients with Mycobacterium abscessus infection immediately, counter to current medical practice.
A UCLA-led study shows that physicians frequently order preventive medical services for adult Medicare beneficiaries that are considered unnecessary and of "low value" by the U.S. Preventive Services Task Force -- at a cost of $478 million per year.
A top-level international research team including researchers from the University of Eastern Finland has developed a new algorithm for the diagnostics of dementia. The algorithm is based on blood and cerebrospinal fluid biomarker measurements. These biomarkers can be used to aid setting of an exact diagnosis already in the early phases of dementia.
A new study draws the most detailed picture yet of SARS-CoV-2 infection in the lung, revealing mechanisms that cause lethal COVID-19 and how COVID-19 differs from other infectious diseases.
Thirty-one new articles were published online ahead of print for Geology in April. Topics include shocked zircon from the Chicxulub impact crater; the Holocene Sonoran Desert; the architecture of the Congo Basin; the southern Death Valley fault; missing water from the Qiangtang Basin; sulfide inclusions in diamonds; how Himalayan collision stems from subduction; ghost-dune hollows; and the history...
The choice between two non-invasive diagnostic tests is a common dilemma in patients who present with chest pain. Yale cardiologist Rohan Khera, MD, MS, and colleagues have developed ASSIST©, a new digital decision-aiding tool.
A new study published in Nature Communications documents an inexpensive, spark-free, optical-based hydrogen sensor that is more sensitive -- and faster -- than previous models.
After surgical removal of a tumor, tests for signs of cancer DNA circulating in the blood typically rely on knowing the mutations that were present in a patient's tumor. A new study has found that a "tumor-uninformed" blood-only test can also detect residual disease.
Scientists from around the world have produced a new analysis--believed to be the most detailed study of specialized ecological data from global forests--that is furthering science's understanding of species interactions and how diversity contributes to the preservation of ecosystem health.
New research shows that the global models used to project how Earth's climate will change in the future underestimate the impact of forest fires and drying climate on forests' ability to capture and store atmospheric carbon.
Today, the G10K sponsored Vertebrate Genomes Project (VGP) announces their flagship study and associated publications focused on genome assembly quality and standardization for the field of genomics. This study includes 16 diploid high-quality, near error-free, and near complete vertebrate reference genome assemblies for species across all taxa with backbones (i.e., mammals, amphibians, birds,...
Obesity and a high-salt diet are both bad for our hearts but they are bigger, seemingly synergistic risks for females, scientists report.
