Jupiter's polar cap is threaded in part with closed magnetic field lines rather than entirely with open magnetic field lines, new research finds.

Researchers have been able to obtain data from underneath Thwaites Glacier, also known as the 'Doomsday Glacier'. They find that the supply of warm water to the glacier is larger than previously thought, triggering concerns of faster melting and accelerating…

The virus that causes tick-borne encephalitis appears to trick the immune system, misdirecting it into producing inferior antibodies. But new research shows some people produce more potent antibodies, providing hope for treatment.

A new study using human genetics suggests researchers should prioritize clinical trials of drugs that target two proteins to manage COVID-19 in its early stages. Based on their analyses, the researchers call for prioritizing clinical trials of drugs targeting…

A tiny protein of SARS-CoV-2, the coronavirus that gives rise to COVID-19, may have big implications for future treatments, according to a team of Penn State researchers.

A new study continues to support a growing body of evidence that aluminum contributes to the pathogenesis of Alzheimer's disease (AD). Researchers found aluminum co-located with phosphorylated tau protein, which is an early initiator of AD.

Psychosocial stress - typically resulting from difficulty coping with challenging environments - may work synergistically to put women at significantly higher risk of developing coronary heart disease, according to a new study.

The properties of carbon-based nanomaterials can be altered and engineered through the deliberate introduction of certain structural 'imperfections'. The challenge, however, is to control the number and type of these defects. Chemists and materials scientists…

Throughout the last ice age, the climate changed repeatedly and rapidly during so-called Dansgaard-Oeschger events, where Greenland temperatures rose between 5 and 16 degrees Celsius in decades. When certain parts of the climate system changed, other parts of…

Researchers have made a significant discovery in the field of materials science, for the first time providing a full picture of how fatigue in ferroelectric materials occurs.

In some men, having traditional masculine characteristics such as competitiveness and adventurousness was linked to being better fathers to infants, a new study found. But the men in this study - highly educated and from dual-earner couples - combined those…

The concentration of the radioactive element radon is known to change in the ground before and after earthquakes. Previous studies have shown elevated radon levels in the atmosphere before the mainshock of a large inland earthquake due to foreshock activity…

A twin study indicates that the machinery responsible for energy handling in fat tissue is working poorly in obesity. In the study, a clear reduction was seen in the activity of mitochondrial genes in obesity in fat tissue, while similar genome-level change in…

A new study reveals the involvement of interleukin-33, an important alarm signal, when immune cells get exposed to Sars-CoV-2 for a second time.

Researchers succeed in producing rapid, cost-effective and environmentally friendly material.

A team of scientists has analyzed how microbes in the gut process the plant-based, sulfur-containing sugar sulfoquinovose. Their study discovered that specialized bacteria cooperate in the utilization of the sulfosugar, producing hydrogen sulfide. This gas has…

Researchers have discovered that bird blood produces more heat in winter, when it is colder, than in autumn.

A research team has uncovered a new technique that can speed up recovery from bone replacements. Novel micropillars, 10 times smaller than the width of a human hair, can change the size, shape and nucleus of individual stem cells and 'trick' them to become…

For those who have sickle cell disease, there are only a few treatment options, which include bone marrow transplants, gene therapy or other treatments that address a subset of symptoms. Now, researchers report discovery of a small molecule that could treat…

A dementia diagnosis turns the world upside down, not only for the person affected but also for their relatives, as brain function gradually declines. Those affected lose their ability to plan, remember things or behave appropriately. At the same time, their…

Exercise and a healthy diet in childhood leads to adults with bigger brains and lower levels of anxiety, according to new research.

As demonstrated by multiple studies, women who breastfeed have a lower risk for developing cardiovascular disease and diabetes, though the mechanisms by which these risks are reduced for lactating women are still not fully understood. Scientists recently…

Dengue risk is exacerbated in highly populated areas of Brazil after extreme drought because of improvised water containers housing mosquitoes, suggests a new study.

Sunnier areas are associated with fewer deaths from COVID-19, an observational study suggests. Increased exposure to the sun's rays -- specifically UVA -- could act as a simple public health intervention if further research establishes it causes a reduction in…

The first large study showing that leisure time physical activity and occupational physical activity have opposite, and independent, associations with cardiovascular disease risk and longevity.

A new study shows how the principles of Mario Kart -- especially the parts of it that make the game fun for players -- can be applied to reduce world poverty and improve sustainability in farming and agriculture.

Scientists have discovered a surprising response in lung cells infected with the SARS-CoV-2 virus, which might explain why the disease is so difficult to treat. The researchers suggest testing a new pairing of drugs to combat the disease.

Researchers have managed to visualize the vortex tubes in a quantum fluid, findings that could help researchers better understand turbulence in quantum fluids and beyond.

The network of nerves connecting our eyes to our brains is sophisticated and researchers have now shown that it evolved much earlier than previously thought, thanks to an unexpected source: the gar fish.

For nearly a decade, scientists have relied on an MRI-based map, or atlas, of the pig brain - developed using 4-week-old pigs - to understand where and how nutrients and other interventions affect the developing brain. Now, scientists have updated that atlas,…
