Scientists have studied how the screen habits of US children correlates with how their cognitive abilities develop over time. They found that the children who spent an above-average time playing video games increased their intelligence more than the average, while TV watching or social media had neither a positive nor a negative effect.

Scientists have, for the first time, grown plants in soil from the Moon. They used soil collected during the Apollo 11, 12 and 17 missions. In their experiment, the researchers wanted to know if plants would grow in lunar soil and, if so, how the plants would respond to the unfamiliar environment, even down to the level of gene expression.

How does a cell balance risk and speed when dividing? Scientists have developed and experimentally tested the first mathematical theory that describes the cell's best strategy for dividing safely and efficiently.

A new method of detecting mega earthquakes, which picks up on the gravity waves they generate by using deep-learning models, can estimate earthquake magnitude in real time and provide earlier warning of tsunamis.

The famous double slit experiment shows that particles can travel on two paths at the same time -- but only by looking at a lot of particles and analysing the results statistically. Now a two-path-interference experiment has been designed that only has to measure one specific particle to prove that it travelled on two paths.

Liquid fuels with high energy density, though used worldwide, are dangerous to transport and store owing to their volatility, which produces explosive gas mixtures. To address this problem, researchers recently investigated the possibility of storing liquid fuel within polymeric gel networks, preventing their fast evaporation, and demonstrating good combustion performance. Their work paves the way for safer transport and storage of liquid fuels.

By clarifying the role of 'real' and 'virtual' charge carriers in laser-induced currents, researchers have taken a decisive step toward creating ultrafast computers.

After running simulations on the world's most powerful supercomputer, an international team of researchers has developed a theory for the nuclear structure and origin of carbon-12, the stuff of life. The theory favors the production of carbon-12 in the cosmos.

A new study has revealed the strongest evidence to date that all bison in North America carry multiple small, but clearly identifiable, regions of DNA that originated from domestic cattle.

Perovskite materials may hold the potential to play an important role in a process to produce hydrogen in a renewable manner, according to a recent analysis. Hydrogen has emerged as an important carrier to store energy generated by renewable resources, as a substitute for fossil fuels used for transportation, in the production of ammonia, and for other industrial applications.

Fruit flies synchronize the movements of their heads and bodies to stabilize their vision and fly effectively, according to researchers who utilized virtual-reality flight simulators. The finding appears to hold true in primates and other animals, the researchers say, indicating that animals evolved to move their eyes and bodies independently to conserve energy and improve performance. This understanding could inform the design of advanced mobile robots.

Global warming can result in the spread of peatland vegetation in the Arctic. An international research group has discovered signs of 'proto-peat', which may be the beginning of new peatlands.

The Westdahl Peak volcano in Alaska last erupted in 1992, and continued expansion hints at another eruption soon. Experts previously forecasted the next blast to occur by 2010, but the volcano -- located under about 1 kilometer of glacial ice -- has yet to erupt again. Using the Westdahl Peak volcano as inspiration, a new volcanic modeling study examined how glaciers affect the stability and short-term eruption cycles of high-latitude volcanic systems -- some of which exist along major air transportation routes.

In June 2019, a magnitude 4.0 earthquake occurred beneath Lake Erie just off the shoreline of Ohio, about 20 miles northeast of Cleveland.

Pervasive parasitic infections reduce herbivory rates and can therefore trigger trophic cascades that impact plant communities, according to new research. This work helps fill a recognized knowledge gap regarding the ecological consequences of parasitic infections in natural ecosystems.

Researchers have devised a potentially easier way of gazing into the abyss. Their imaging technique could allow astronomers to study black holes smaller than M87's, a monster with a mass of 6.5 billion suns, harbored in galaxies more distant than M87, which at 55 million light-years away, is still relatively close to our own Milky Way.

Scientists used an unprecedented technique to detect that levels of helium are rising in the atmosphere, resolving an issue that has lingered among atmospheric chemists for decades.

Researchers have examined the mass extinction of large animals over the past tens of thousands of years and found that extinct species had, on average, much smaller brains than species that survived.

Scientists identified the most relevant predictive variables for anticipating hospital demand and proposed using an ensemble model based on the average of the predictions of several individual models.

A major hurdle for work at the forefront of fundamental physics is the inability to test cutting-edge theories in a laboratory setting. But a recent discovery opens the door for scientists to see ideas in action that were previously only understood in theory or represented in science fiction.
