Waves and Their Applications in Technologies for Information Transfer
- Physics
Nuclear clocks are nearly here
More precise clocks could improve technologies such as GPS and help scientists test major ideas in science.
- Physics
Light from space has record-breaking energy
Hundreds of newly detected gamma rays hint at environments in the cosmos that accelerate particles to energy extremes.
- Chemistry
Sleep-friendlier lighting is on the way
Chemists have created a new glowing material for LEDs. It should lessen how much near-bedtime lighting impairs your ability to nod off.
- Physics
Stars made of antimatter could lurk in our galaxy
Fourteen sources of gamma rays in our galaxy look like they could be antistars — celestial bodies made of antimatter.
- Computing
Will this smartphone app become your exercise coach?
When one teen couldn’t go to the gym, she invented an app to bring her gymnastics coach to her home. She succeeded and won a major award for it.
- Computing
New device gets power from 5G signals grabbed from the air
A new way to harvest electricity relies on a tiny array of antennas and a lens. Together, they collect and focus 5G signals coming from any direction.
- Earth
Light levitation might help explore Earth’s ‘ignorosphere’
A toy called a light mill inspired researchers to invent a new way to fly. They’re using light to levitate small nanotube-coated discs.
- Space
Ingenuity helicopter makes history by flying on Mars
The copter's 40-second-long flight in the Red Planet’s thin air is only the first in a planned series of daring flights.
- Physics
Getting cozy with a science experiment
Items you use in your home can inspire a scientific experiment.
- Planets
Signs of a hidden Planet Nine in our solar system may be an illusion
Hints of the remote planet, also called Planet X, relied on clumped up orbits of bodies beyond Neptune. A new study suggests that clumping doesn’t exist.
- Physics
Scientists Say: Radiation
Radiation is the motion of energy through space as waves or particles.
- Computing
5G promises new energy savings for digital tech
A new way to transmit wireless communications promises time and energy savings by using networks of smaller cells.
