New drone technology improves ability to forecast volcanic eruptions

Specially-adapted drones have been gathering data from never-before-explored volcanoes that will enable local communities to better forecast future eruptions. The cutting-edge research at Manam volcano in Papua New Guinea is improving scientists' understanding of how volcanoes contribute to the global carbon cycle, key to sustaining life on Earth.

Water on ancient Mars

A meteorite that originated on Mars billions of years ago reveals details of ancient impact events on the red planet. Certain minerals from the Martian crust in the meteorite are oxidized, suggesting the presence of water during the impact that created the meteorite. The finding helps to fill some gaps in knowledge about the role of water in planet formation.

Coronavirus mutation may have made it more contagious

A study involving more than 5,000 COVID-19 patients in Houston finds that the virus that causes the disease is accumulating genetic mutations, one of which may have made it more contagious. This mirrors a study published in July that found that around the world, viral strains with the same genetic mutation quickly outcompeted other strains.

Asteroid's scars tell stories of its past

Asteroid Bennu only recently migrated into Earth's neighborhood, according to a detailed analysis of impact marks on boulders on its surface. The report provides a new benchmark for understanding the evolution of asteroids and offers insights into space debris hazardous to spacecraft.

China's most important trees are hiding in plain sight

Scientists have synthesized long-term biodiversity data from 12 immense forest study plots spanning 1,500 miles, from China's far north to its southern tropics. Their results point to maple trees - long appreciated for their autumn foliage and the syrup that graces our tables - as potential foundation species in both China and North America.

A malformation illustrates the incredible plasticity of the brain

One in 4,000 people is born without a corpus callosum, a brain structure consisting of neural fibers that are used to transfer information between hemisphere. 25% of them do not have any symptoms. Neuroscientists discovered that when the neuronal fibers that act as a bridge between the hemispheres are missing, the brain reorganizes itself and creates an impressive number of connections inside each...

Future lake food webs in Subarctic have more biomass and contain more omega-3 fatty acids

Subarctic regions are facing rapid changes in climate and land-use intensity. An international research team recently completed an investigation to see how these changes are affecting the food webs and fish communities of lakes in northern Finland. Biomasses and omega-3 fatty acids, EPA and DHA, were determined from the algal producers at the base of food web to large carnivorous fish from 20...
