New technology can get inside your head. Are you ready?
New technologies aim to listen to — and maybe even change — your brain activity. But just because scientists can do this, should they?

Space station sensors saw how weird ‘blue jet’ lightning forms
A mysterious type of lightning in the upper atmosphere has been traced to a brief, bright flash of light at the top of a storm cloud.

Bye-bye batteries? Power a phone with fabric or a beacon with sound
New piezoelectric systems produce electricity in unusual ways, such as when a certain nylon bends or underwater ceramics vibrate.

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.

Let’s learn about solar power
Solar power is a way to harness energy from the sun, and lessen our reliance on fossil fuels.
- Space
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.
- Brain
Confidence can make you miss important information
Being confident can feed a confirmation bias in us, new studies show. This bias can make your brain ignore other people’s ideas and any conflicting information.

Understanding light and other forms of energy on the move
Radiation needn’t be scary, especially if it allows us to see our family or use our cell phones. Here’s a guide to light and other types of emitted energy.
- Physics
A contrast between shadows and light can now generate electricity
A new device exploits the contrast between bright spots and shade to produce a current that can power small electronics.

Zapping the brain may make it work right again
Sending electrical zaps to electrodes implanted deep in the brain can help people with Parkinson’s disease, depression and even obsessive-compulsive disorder.

Study appears to rule out volcanic burps as causing dino die-offs
New data on when massive volcanic eruptions happened do not match when the dinosaur mass extinction took place.
