Scientists have tracked a cuckoo's migratory flight from Africa to its breeding ground in Mongolia.
Consumers often struggle to achieve self-set life improvement goals, but what if deliberately emulating the successful strategies used by their friends could help them?
Researchers have found that the chance of a false negative result -- when a virus is not detected in a person who actually is, or recently has been, infected -- is greater than 1 in 5 and, at times, far higher.
The COVID-19 pandemic has magnified the social, educational and health care disparities already plaguing the nearly 40 million Americans the US Census Bureau estimates are living in poverty. Perhaps the hardest hit members of that population, say pediatricians, are children from low-income households.
Researchers have discovered a phenomenon that could be harnessed to control the movement of tiny particles floating in suspension. This approach, which requires simply applying an external electric field, may ultimately lead to new ways of performing certain industrial or medical processes that require separation of tiny suspended materials.
Shake, rattle and roll. Even though they are miles from the epicenter of an earthquake, buildings can collapse due to how an earthquake energy makes the ground shake and rattle. Now, a team of engineers has designed a flexible material that can help buildings withstand multiple waves of energy traveling through a solid material, including the simultaneous forward and backward and side-to-side...
Correlation discovered between magnetic turbulence in fusion plasmas and troublesome blobs at the plasma edge.
Giving beneficial bacteria to stressed mothers during the equivalent of the third trimester of pregnancy prevents an autism-like disorder in their offspring, according to a new animal study.
Organized crime groups have adapted their illegal operations to the COVID-19 pandemic and are successfully scamming Canadians, according to the RCMP. Experts say they are behind cyberscams and the trade in counterfeit and substandard medical...
With the weather looking up, SpaceX and NASA officials vowed Tuesday to keep crew safety the top priority for the nation's first astronaut launch to orbit in nearly a decade.
Electrolysis, passing a current through water to break it into gaseous hydrogen and oxygen, could be a handy way to store excess energy from wind or solar power. The hydrogen can be stored and used as fuel later, when the sun is down or the winds are calm.
Scientists have known for a decade that cells that fuse with others to perform their essential functions—such as muscle cells that join together to make fibers—form long projections that invade the territory of their fusion partners. But how the thin and floppy polymers involved in this process propel mechanically stiff protrusions has been unknown.
Five years after NASA's MAVEN spacecraft entered into orbit around Mars, data from the mission has led to the creation of a map of electric current systems in the Martian atmosphere.
E-learning could be a crucial tool in the biosecurity fight against invasive alien species such as Japanese Knotweed, Zebra Mussels and Signal Crayfish according to a new study published in the academic journal Biological Invasions.
For the first time, scientists have introduced minuscule tracking devices directly into the interior of mammalian cells, giving an unprecedented peek into the processes that govern the beginning of development.
Just as a literature buff might explore a novel for recurring themes, physicists and mathematicians search for repeating structures present throughout nature.
Spring is in full swing. Trees are leafing out, flowers are blooming, bees are buzzing, and birds are singing. But a recent study published in Proceedings of the National Academy of Sciences found that those birds in your backyard may be changing right along with the climate.
An international research collaboration has developed a mathematical method that can speed up search and rescue operations at sea. The new algorithm accurately predicts locations to which objects and people floating in water will drift.
Analysis of two cosmic explosions indicates to astronomers that the pair, along with a puzzling blast from 2018, constitute a new type of event, with similarities to some supernovae and gamma-ray bursts, but also with significant differences.
In a recent theoretical study, scientists discovered the presence of the Hopfion topological structure in nano-sized particles of ferroelectrics -- materials with promising applications in microelectronics and information technology.
Researchers hope giving Remdesivir along with a powerful anti-inflammatory could be the key to treating the most severe COVID-19 cases.
In living cells, enzymes drive biochemical metabolic processes. It is this very ability which allows them to be used as catalysts in biotechnology, for example to create chemical products such as pharmaceutics. Researchers have identified an enzyme that, when illuminated with blue light, initiates a reaction that was previously unknown in enzymatics.
Researchers have made artificial cilia, or hair-like structures, that can bend into new shapes in response to a magnetic field, then return to their original shape when exposed to the proper light source.
Traffic congestion is a serious problem in the United States, but a new analysis shows that interactive technology -- ranging from 511 traffic information systems and roadside cameras to traffic apps -- is helping in cities that use it.
The interaction between 'transfer RNAs' and the enzymes that help them in protein synthesis has always been the key area of interest for understanding the evolution of the genetic code. Now, a team of scientists reports that a subunit of 'alanyl-tRNA synthetase' enzyme of the primitive microorganism Nanoarchaeum equitans can mimic the super-primitive tRNA 'aminoacylation' independent of the...
Researchers have developed a mathematical formula that, computer simulations suggest, could help 5G and other wireless networks select and share communications frequencies about 5,000 times more efficiently than trial-and-error methods.
In women with a history of miscarriage, higher levels of physical activity were associated with a greater risk of subclinical, or very early, pregnancy loss, according to new research. Among women with confirmed pregnancy, physical activity and miscarriage risk were unrelated.
As astronomers ramp up study of the atmospheres of hot, Jupiter-like planets around other stars, they encounter clouds that obscure study of atmospheric gases. A new computer model looks at the proposals for cloud compositions -- from smog to rubies -- and finds that the most likely, over a large range of temperatures, are silicate clouds: aerosols of silicon and oxygen, like molten quartz or...
