Let’s learn about virtual reality

Scientists use virtual reality to build new games and to help people fight their fears.

Materials Science

This artificial skin feels ‘ghosts’ — things you wish were there

Engineers have developed a wearable device that simulates the sense of touch. It may benefit robotic surgery and deep-sea exploration.

Computers are changing how art is made

Some people have challenged the idea that artificial intelligence can be creative. But new software can provide inspiration to artists or fully partner with them in the creative process.

Computing

Explainer: What is an algorithm?

These step-by-step instructions underlie social media, internet searches and other computer-based activities. But what are they exactly? We explain.

Chemistry

Ordinary paper turns into flexible human-powered keypad

Engineers have figured out how to turn sheets of paper into rugged, low-cost electronic devices, such as a computer keypad.

Materials Science

‘Frozen smoke’ could protect electronics from annoying static

A fluffy material made from cellulose nanofibers and silver nanowires can protect electronic devices by blocking more than 99.99 percent of disrupting interference, a new study reveals.

Health & Medicine

Surviving Mars missions will take planning and lots of innovation

Astronauts that go to Mars will need protection from microgravity and radiation, plus mini-medical devices to diagnose problems and manage emergencies.

Environment

Batteries not included: This Game Boy look-alike doesn’t need them

Game Boy revolutionized the gaming industry. A newer version could help slow the rate of climate change.

Physics

Trees power this alarm system for remote forest fires

Wind moving through tree branches is all the energy needed to power devices that can detect a remote fire before it rages into an uncontrolled inferno.

Physics

This high-tech sweeper is designed for super-clingy moon dust

An electron beam is the newest tool being developed to remove sticky and damaging lunar dust from surfaces.

Materials Science

Will bacterial ‘wires’ one day power your phone?

An accidental discovery helps scientists generate electricity out of thin —but humid — air with bacteria-made protein nanowires.
