This startup is trying to solve lab-grown meat’s biggest problem
A biotech startup has developed a new kind of bioreactor that could help increase cultivated meat production.
Future nuclear power reactors could rely on molten salts — but what about corrosion?
Proton irradiation decreases the rate of corrosion in certain metal alloys — potentially good news for promising nuclear power reactors .
Why aren’t there solar-powered cars?
There are a number of reasons why solar-powered cars aren’t an option for everyday travel, at least not yet.
3D-printed “metamaterial” is stronger than anything in nature
Australian scientists used an advanced 3D printing technique to create a super strong, super lightweight new “metamaterial.”
Artificial reef designed by MIT engineers could protect marine life, reduce storm damage
An MIT team is hoping to fortify coastlines with “architected” reefs engineered to mimic the wave-buffering effects of natural reefs.
Korea’s “artificial sun” sets nuclear fusion record
An upgrade to KSTAR, an “artificial sun” in Korea, enabled scientists to set a new world record in nuclear fusion.
“Stone wool”: lava-based material is more efficient, lasts longer than most insulation materials
Stone wool, a lava-based material, is more efficient and lasts longer than today's most common insulation materials.
Expert explains why a nearly new Boeing 737 MAX 9 door flew off
A 60-pound “door plug” blew out from a nearly new Boeing 737 MAX 9 in flight at 16,000 feet, leaving a gaping hole in the fuselage. Why?
Safer skies with self-flying helicopters
Engineers start with an existing helicopter model and add control, sensing, and other software systems to make it autonomous.
