Hijacking a cell process called RNA interference can let scientists turn off a selected gene. Its silencing can point to what genes do when they’re on — and may lead to new treatments for disease.
Questions for Silencing Genes
Biologists had suspected the deep seafloor would be little more than barren sediment. But they found a surprising amount of oxygen — and life.
Plate tectonics is the process whereby Earth continually rebuilds itself — and causes destructive events like earthquakes and volcanic eruptions.
Rapid warming in the Arctic is sapping summer storms of their power to cool. That worsens heat waves across the Northern Hemisphere.
A new 2-in-1 desktop machine quickly recycles plastic trash into low-cost 3-D printer ‘ink’ at the push of a button.
Scientists in South Korea have developed a fabric that captures energy from its wearer’s motions and turns it into electricity.
Grit in one of Saturn’s rings likely formed in hot water on the planet’s ice-covered moon Enceladus. That suggests conditions on this moon might be able to support life.
Rabbits may breed rapidly, but not fast enough to compensate for the huge summer appetites of huge pythons roaming Florida’s Everglades.
Stress and anxiety can lead to serious mental and behavioral problems. Identifying stressors can help people cope with anxiety. Even better, viewing stress as a strength can tone down anxious feelings and boost productivity.
Questions for Stress for Success
A new bird flu virus threatens to spread outside of China. Experts traced the germ to markets where live chickens are sold.
Plastic in the ocean is a growing problem. New research finds that corals may eat tiny bits of plastic, prompting new concerns about the health of living reefs.
A massive galaxy’s gravity is so strong that it bends light, creating a “lens” in space. This natural magnifying glass is giving astronomers a rare view of a supernova on the other side of the universe.
Bisphenol chemicals are the basic building block of many common plastics. Some governments have banned BPA from baby bottles. But mounting evidence suggests that its replacement, BPS, may be no safer.
A few stars have been spotted departing our galaxy. The fastest of these might have been propelled by another exploding star, a new study finds.
New tools are giving scientists an unprecedented glimpse into the behaviors of whales and dolphins. And these new data are upending long-held assumptions.
Questions for Risso’s Dolphins
The supercontinent Pangaea started breaking apart 200 million years ago. This may have been triggered by the shrinking of the Tethys Ocean, a new study finds.
The Intel Science Talent Search is America’s top high school science competition. This year, the top finishers took home more than $1 million in prizes.
