These metal flowers open and close based on the temperature around them, in a process known as thermal expansion. A bimetal coil expands when it’s hot and contracts when it’s cold, allowing the flowers to act like their natural counterparts without electricity. Creator and Aerospace Engineer Greg Mathy from Bimetal Creations has a Kickstarter campaign for…

When researchers used to try to diagnose and treat diseases, they would often search for one mutation on a single gene that was causing the problem. Or maybe they would look for average effects of a mutation that led to a disease across the entire population. But these approaches ignored the complexities and specifics that…

If doctors knew which trauma survivors would develop Posttraumatic Stress Disorder, or PTSD, when the patients arrived at the emergency room, they could prevent it from occurring in the first place. Sisi Ma, a research scientist at New York University’s Langone Medical Center, presented her work trying to do just that at the Leveraging Big…

Once you suck smog out of the air, what should you do with it? Pollution particles are mostly made up of carbon, so Dutch Artist Daan Roosegaarde decided to compress them into jewelry in a nod to diamond, carbon’s sparkliest allotrope. The device extracting this pollution powder is Studio Roosegaarde’s Smog Free Tower, a 23-foot-tall…

Expedition 44 launched from Kazakhstan around 5 p.m. ET on Wednesday and arrived at the International Space Station at 10:45 p.m. ET.

No images were more captivating this week than those released from our reconnaissance of the last great world in our solar system, Pluto. The New Horizons spacecraft completed its nearly decade-long journey to the dwarf planet, cruised past it at 35,000 miles per hour, and will beam its images and data back to earth over…

I had sporadically seen mysterious nitrogen canisters on New York City sidewalks, and wondered what they were doing there. Each tank has a hose snaking its way into a manhole, where it presumably dispenses nitrogen under the street. Luckily, Popular Science let me find out as part of my job (booyah). It turns out they’re…
