A team of researchers have developed a new metric called the stopover-to-passage ratio that can help determine if a majority of birds are flying over a particular site or stopping at the site to refuel or rest. The answer to this question can have important implications for what action is ultimately taken on the ground to help migratory birds.
Treatment with a peptide that mimics the naturally occurring protein GIV prevents immune overreaction and supports a mechanism critical for survival in mouse models of sepsis and colitis, according to a new study.
The way leaves reflect light, known as plant reflectance spectra, can illuminate the evolutionary history of seed plants, according to researchers. The researchers found that by measuring the light spectrum reflected by leaves, they can identify the plant and its chemistry, evolution and place in the tree of life.
Researchers have taken an important step toward explaining why genetically identical cells can produce varying amounts of the same protein associated with the same gene. Researchers demonstrated that most of the fluctuations in gene expression between identical cells occur in the first step of protein production, called transcription.
New studies suggest people with blood type O may have a lower risk of COVID-19 infection and reduced likelihood of severe outcomes, including organ complications, if they do get sick.
Researchers have identified a blood profile that could help identify COVID-19 patients at greatest risk of deterioration and direct them towards trials of specific treatments that could modify their immune systems' responses.
Autism is considered a disorder of the brain. But a new study suggests that the peripheral nervous system, the nerves that control our sense of touch, pain and other sensations, may play a role as well.
Understanding sounds in language is a critical building block for child literacy, yet this skill is often overlooked. Researchers have now developed a new software tool to assess children's phonological awareness -- or, how they process the sound structure of words.
Researchers have developed a microchip technology that can convert invisible near-infrared laser light into any one of a panoply of visible laser colors, including red, orange, yellow and green. Their work provides a new approach to generating laser light on integrated microchips.
Physicists have made a breakthrough in the long sought-after quest for a room-temperature superconductor, what they call the 'holy grail' of energy efficiency.
A new set of assessment tools shows promise in capturing how the COVID-19 pandemic affects patterns of criminal activity.
Researchers reveal in a mouse study that chronic jet lag alters the microenvironment surrounding tumor cells, making it more favorable for tumor growth, and also hinders the body's natural immune defenses.
On average, about a third of women between 15 and 34 years old from 43 low- and middle-income countries (LMIC) have lost at least one sibling before the age of 25, according to a new study.
A new model can more accurately and efficiently assess which children are at highest risk of preventable death, according to a new study.
In a randomized clinical trial, the effectiveness of different strategies for boosting physical activity varied according to participants' demographic, psychological, and behavioral characteristics.
Recent years have witnessed a widespread and catastrophic decline in the number of forest elephants in protected areas in Côte d'Ivoire, according to a new study.
The range of AI technologies available for dealing with brain disease is growing fast, and exciting new methods are being applied to brain problems as computer scientists gain a deeper understanding of the capabilities of advanced algorithms. Researchers conducted a systematic literature review to understand the state of the art in the use of AI for brain disease. Their qualitative review sheds...
Lustrous metallic paints are used to enhance the beauty of many products, such as home decorations, cars and artwork. But most of these pigments owe their sheen to flakes of aluminum, copper, zinc or other metals, which have drawbacks. Now, researchers have developed organic-only dyes that can form films resembling gold or bronze, without the need for metals.
Growing global demand for palm oil has led to a rapid spread of oil palm monoculture plantations in South East Asia, often associated with the loss of habitats and biodiversity. Plantations are uniformly structured, offering little space for different species. Diversification using indigenous tree species can help. Researchers found diversification can be encouraged through information campaigns...
An injury to the anterior cruciate ligament (ACL) can lead to severe osteoarthritis in both animal and human patients. Now, a new interdisciplinary study on the protein that lubricates our joints says that lubricant may actually be a precursor of joint disease.
Discussions about immigration are heated, even antagonistic. But what happens when supporters and opponents undertake to show more empathy? A study reveals that people who support immigration are ready and willing to adopt an empathetic approach and a wider perspective. By contrast, when opponents of immigration are asked to engage in perspective taking, they feel more competition with their...
A retrospective study of 52 COVID-19 patients may help researchers better understand why not everyone show symptoms of the disease. The study's authors found that asymptomatic patients hosted viral loads comparable to those of symptomatic patients, but asymptomatic patients showed higher levels of lymphocytes (a type of white blood cell responsible for immune responses), cleared the viral...
Rapid detection of the SARS-CoV-2 virus, in about 30 seconds following the test, has had successful preliminary results. The test uses a nanotube-based electrochemical biosensor, a similar technology used for detecting tuberculosis and colorectal cancer as well as detection of biomarkers for food safety.
Results of a retrospective analysis suggest that people born with a heart defect who developed COVID-19 symptoms had a low risk of moderate or severe COVID-19 infection, according to a new article.
