Disabilities don’t stop these experts in science and tech
People with disabilities are as varied as the careers some of them pursue in science, technology, engineering and math.
- Chemistry
Scientists Say: Photochromic
Photochromic chemicals change shape when exposed to a specific wavelength of light. The shape change changes the chemical’s color.

Gravitational waves detected yet again
For the third time in 16 months, scientists have announced detection of gravitational waves washing over the spacetime environment in which Earth resides. This seems to show that such waves may not be rare.

Ancient Arctic ‘gas’ melt triggered enormous seafloor explosions
Methane explosions 12,000 years ago left huge craters in bedrock on the Arctic seafloor. Scientists worry more could be on the way today as Earth’s ice sheets melt.

BPA-free plastic may host BPA-like chemical, teen finds
Something has to replace the BPA in ‘BPA-free’ plastics. A teen has been probing what that is.

When is an epileptic seizure about to strike?
Two high-school research projects suggest ways to identify early warnings of a coming epileptic seizure. This might give people time to free themselves from potentially dangerous activities.

Needle-free blood typing may be on the way
A teen in Kuwait presents data suggesting how, one day, it may be possible to figure out your blood type just by shining infrared light into your skin.

Auto-focus eyeglasses rely on liquid lenses
Engineers have designed what could be the last eyeglasses anyone would need. Right now, they’re bulky but smart. Liquid lenses are key to their adjustability — and those lenses focus automatically.
