Waves and Their Applications in Technologies for Information Transfer
- Computing
A single chip like this could transmit a world’s worth of data
The internet has a big environmental footprint. But this new type of tech could help reduce the climate impact of computing.
- Materials Science
Analyze This: Algae behind blue-glowing waves light up a new device
Some algae glow blue when they experience forces. Held in transparent plastic, they now make devices light up in response to gentle pushes and tugs.
- Physics
In a breakthrough experiment, fusion gave off more energy than it used
The sun creates energy through nuclear fusion. Now scientists have too. This achievement raises hopes for developing a new type of clean energy.
- Computing
Sleep helps AI models learn new things without forgetting old ones
Breaks in training meant to mimic human sleep helped artificial intelligence learn multiple tasks.
- Earth
Scientists Say: Seismology
Seismology is the branch of science focused on seismic waves — vibrations that run through or around Earth.
- Humans
When it comes to dance, it’s all about the bass
During a concert, people danced more when they were bathed in sounds that were too low for their ears to hear.
- Climate
Green energy is cheaper than fossil fuels, a new study finds
Switching over to clean, renewable power — and away from fossil fuels — could save trillions of dollars by 2050, a new study finds.
- Chemistry
Was that fingerprint left during a crime? A new test may answer that
In what could be a boon to forensics, Iowa State University chemists have come up with a way to analyze the age of fingerprints.
- Computing
Scientists Say: Artificial intelligence
Artificial intelligence is technology smart enough to do tasks that would normally require human brainpower.
- Tech
Will the internet soon reach the one-third of people without it?
Access to the internet is a human right, yet much of the world can’t get online. New tech has to be affordable and usable to end this digital divide.
- Tech
A tool as small as a human cell can scan for contaminants and more
Tiny spectrometers might someday show up on smart devices. They could help people scan for ingredients or contaminants in foods and other materials.
- Chemistry
Scientists Say: Fluorescence
This property causes materials — including some animals’ skin, fur or feathers — to glow under light.
