Sleepy mosquitoes prefer dozing over dining
Mosquitoes repeatedly shaken to prevent slumber lagged behind well-rested ones when offered a leg to feed on.

You might someday ‘wallpaper’ your bedroom with this loudspeaker
This thin, flexible and lightweight loudspeaker could reduce noise in loud spaces. It also might enable listeners to experience sound in new ways.
- Physics
When dominoes fall, how fast the row topples depends on friction
Two types of friction help determine how quickly a line of dominoes collapses, computer modeling shows.
- Chemistry
Simple process destroys toxic and widespread ‘forever’ pollutants
Ultraviolet light, sulfite and iodide break down these PFAS molecules faster and more thoroughly than other methods.
- Space
Let’s learn about surviving a trip to Mars
Getting to and surviving on the Red Planet will take lots of innovation.
- Computing
A new supercomputer just set a world record for speed
Able to perform more than a quintillion calculations per second, it will allow scientists to study exploding stars, subatomic particles and more.
- Computing
Scientists Say: Supercomputer
These ultrafast computers perform complex calculations for research on cancer, quantum physics and more.
- Tech
Virtual critters evolve bodies that help them learn
A combination of evolution and learning may lead to more intelligent and agile robots.
- Health & Medicine
To test for COVID-19, a dog’s nose can match a nose swab
Dogs can sniff out COVID-19 cases as well as PCR tests can — and are better at ID’ing cases having no symptoms, a new study finds.
- Science & Society
Some scientists want serious research into UFOs. Here’s why
Science grapples with unknown phenomena all the time. Investigating “unidentified flying objects” shouldn't be different, researchers say.
- Space
A massive rogue roaming our galaxy may be a black hole
Alternatively, this unseen wanderer might be a hefty neutron star. Whatever it is, its gravity caused starlight to be warped — and that gave it away.
- Tech
This robotic finger is covered in living human skin
The advance brings super realistic cyborgs one small step closer to reality.
