Astronomers have detected a stinky, toxic gas in Venus’ clouds that could be a sign of life, or some strange unknown chemistry. | Continue reading
The biggest merger of two black holes so far raises questions about how the pair of objects came to be. | Continue reading
Tiny clumps of bacteria can survive at least three years in outer space, raising the prospect of interplanetary travel by microbial life. | Continue reading
A gap in the energy levels of positronium seems to be substantially larger than predicted, and physicists don’t know why. | Continue reading
High-speed 3-D microscopy and mathematical analyses reveal that rolling and lopsided tail flicks keep the cells swimming in a straight line. | Continue reading
Investing in halting deforestation and limiting the wildlife trade could be a cost-effective way to reduce the risk of pandemics, a new analysis finds. | Continue reading
Computer simulations and observations of nearby galaxies let astrophysicists put a firm number on the Milky Way's size. | Continue reading
A theoretical study could help physicists searching for a theory of quantum gravity. | Continue reading
People generally convert a dog’s age to human years by multiplying its age by seven. But a new study shows the math is way more complex. | Continue reading
A new X-ray map of the entire sky, using data from the eROSITA telescope’s first full scan, looks deeper into space than any other of its kind. | Continue reading
The first evidence of an object more massive than any neutron star and more lightweight than any black hole has astronomers wondering what it is. | Continue reading
In the lab, a few carp eggs survived and even hatched after being pooped out by ducks. The finding may help explain how fish reach isolated waterways. | Continue reading

Conflicting reports offer little clarity about whether COVID-19 targets the brain. | Continue reading
It’s now known that a Modigliani’s lizard, first found in 1891 in Indonesia, is bright green but can shift shades like a chameleon. | Continue reading
Astronomers have used fast radio bursts as cosmic weigh stations to tease out where the universe’s “missing matter” resides. | Continue reading
Life, time, intelligence — plenty of terms used in science have imprecise definitions. | Continue reading
Cold atoms can form crystals as a result of the Pauli exclusion principle. | Continue reading
People who recover from COVID-19 but later test positive again for the coronavirus don’t carry infectious virus, a study finds. | Continue reading
Quantum mysteries can be avoided if reality encompasses possibilities as well as actualities, a new paper proposes. | Continue reading
Claude Shannon, born 100 years ago, devised the mathematical representation of information that made the digital era possible. | Continue reading
Most children need help learning to read, but there’s long-standing disagreement on how best to help them. Decades of research have identified the most effective approaches. | Continue reading
Mathematical models explain why large gatherings are especially dangerous in an epidemic, and identify how large is too large. | Continue reading
The latest volume of Einstein’s papers covers the infancy of quantum mechanics and new challenges to the theory of relativity. | Continue reading
Sturdy types of plastic may persist in seawater for much long than scientists previously thought. | Continue reading
A new study of cells in lab dishes hints at why viruses found in bats tend to be so dangerous when they jump to other animals. | Continue reading
Infections and deaths on the Diamond Princess suggest that, in the real world, 0.5 percent of COVID-19 infections in China end in death. | Continue reading
China’s Yutu-2 rover found layers of fine sand and coarse gravel under the surface of the moon’s farside. | Continue reading
At least two ancient paths to urban development existed, some archaeologists argue. | Continue reading
Verifying proofs to very hard math problems is possible with infinite quantum entanglement. | Continue reading
Experiments test the effectiveness and safety of human composting, which may soon be an alternative to burial or cremation in Washington state. | Continue reading
To slip past predators, beaked whales appear to synchronize their deep dives, staying silent while not hunting and ascending far from where they dove. | Continue reading
Circulation in the top 2,000 meters of the world’s oceans has increased as a result of faster winds around the globe, a study suggests. | Continue reading
Physicists decreased a nanoparticle’s motion to the lowest level allowed by quantum mechanics. | Continue reading
