Mars had a global magnetic field much earlier -- and much later -- than previously known. Analysis of new satellite data found clear evidence of a magnetic field coming from a lava flow that formed less than 3.7 billion years ago, half a billion years after many people thought the Martian dynamo had ceased. The researchers also detected low-intensity magnetic fields over the Borealis Basin,...

More than a thousand years ago, people from across the Southeast regularly traveled to a small island on Florida's Gulf Coast to bond over oysters, likely as a means of coping with climate change and social upheaval.

The mechanism underlying Parkinson's dyskinesia has been unknown, until now. An international collaboration has found a key cause, and with it, potentially, a new route to providing relief.

Using the most advanced Earth-observing laser instrument NASA has ever flown in space, scientists have made precise, detailed measurements of how the elevation of the Greenland and Antarctic ice sheets have changed over 16 years.

The first step in many light-driven chemical reactions, like the ones that power photosynthesis and human vision, is a shift in the arrangement of a molecule's electrons as they absorb the light's energy. This subtle rearrangement paves the way for everything that follows and determines how the reaction proceeds. Now scientists have seen for the first time how the molecule's electron cloud...

This study sheds new light on the body's initial response to dengue virus infection, describing the molecular diversity and specificity of the antibody response. These results identify an unappreciated role for DENV-reactive IgA antibodies and set the stage for future work to fully characterize the body's immune response to DENV, understand risk factors to severe dengue and ultimately could be...

Certain genetic changes, termed 'pathogenic variants,' substantially increase risk for cardiovascular disease and cancer--the leading causes of death -- but testing to identify individual carriers is not part of current clinical practice.

Chronic exposure to inhaled nicotine alone increases blood pressure in both the body's general circulation and in the lungs that can lead to pulmonary hypertension, according to a new study.

A team of researchers has developed a portable, more environmentally friendly method to produce hydrogen peroxide. It could enable hospitals to make their own supply of the disinfectant on demand and at lower cost.

Native bees that boost food crops are in decline but changing fire management policies could help them. A new study finds these native bees are better able to survive harsh climate events, like drought, in areas where naturally occurring fires are allowed to burn. 

When the master regulator of protein production malfunctions, it may contribute to the development of neuronal diseases such as Alzheimer's and Huntington's.

Like people, neurons need to talk to one another. But instead of turning thoughts into words, these cells convert electrical signals into chemical ones. Scientists have new findings on how one protein triggers this crucial conversion.

Giant elliptical galaxies are not as likely as disk-shaped galaxies, such as our own Milky Way, to be cradles of technological civilizations, according to a recent article by a astrophysicist.

A new study adds to the evidence that people with type 2 diabetes (T2D) are at greater risk of a poor outcome should they become infected with the virus that causes COVID-19. But there is some encouraging news: people with T2D whose blood sugar is well controlled fare much better than those with more poorly controlled blood sugar.

A study of deforestation in Colombia has revealed some valuable insights which could be used to help slow deforestation in areas around the globe.

From snowflakes to quartz, nature's crystalline structures form with a reliable, systemic symmetry. Researchers who study the formation of crystalline materials have shown that it's now possible to control how crystals grow - including interrupting the symmetrical growth of flat crystals and inducing them to form hollow crystal spheres. The discovery is part of a broader design effort focused on...

A new class of self-forming membrane has been developed. Capturing the carbon dioxide which can then be processed, the membrane dramatically reduced the demand for silver and the cost.

Honey bee colonies from across the UK are increasingly suffering from a viral disease, a new study has shown. The team found that the number of honey bee colonies affected with chronic bee paralysis rose exponentially between 2007 and 2017.

Inland waters play an important role in the global carbon cycle. Calculations that scale up the carbon dioxide emissions from land and water surface areas do not take account of inland waters that dry out intermittently. This means that the actual emissions from inland waters have been significantly underestimated -- as shown by the results of a recent international research project.

Researchers have developed a method that could enable scientists to accurately forecast ocean acidity up to five years in advance. This would enable fisheries and communities that depend on seafood negatively affected by ocean acidification to adapt to changing conditions in real time, improving economic and food security in the next few decades.

Researchers can now grow twistronic material at sizes large enough to be useful. While an exciting potential area of nanotechnology, twistronics until now has mostly been explored on samples smaller than human hairs. Now researchers can produce samples on the centimetre scale.

People with the genetic condition neurofibromatosis type 1 (NF1) are prone to developing tumors on nervous system tissue. A new study has found that the development and growth of such tumors are driven by nearby noncancerous neurons and immune cells. The findings point to potential new therapeutic targets for people with NF1.

Scientists have identified a key process in the way bacteria protect themselves from attack -- and it heralds a new strategy in the hunt for antibiotics. The researchers have pieced together how bacteria build their outer, defensive wall -- in essence, the cell's armor plating.

Researchers have gained insights into a promising material for organic light-emitting diodes (OLEDs). The substance enables high light yields and would be inexpensive to produce on a large scale -- that means it is practically made for use in large-area room lighting. Researchers have been searching for such materials for a long time. The newly generated understanding will facilitate the rapid and...
