Superhard materials can slice, drill and polish other objects. They also hold potential for creating scratch-resistant coatings that could help keep expensive equipment safe from damage.

Now, science is opening the door to the development of new materials with these seductive qualities.

Researchers have used computational techniques to identify 43 previously unknown forms of that are thought to be stable and superhard—including several predicted to be slightly harder than or nearly as hard as diamonds. Each new carbon variety consists of carbon atoms arranged in a distinct pattern in a .

Imperial College London biomedical materials scientist Molly Stevens teamed up with Massachusetts Institute of Technology biomedical engineer Sangeeta Bhatia to develop the approach, which they think has the potential to help patients in low-resource and rural areas, where available medical technology may be limited. Stevens specializes in low-cost catalyst-based diagnostics and Bhatia works on creating nanosensors that respond to enzymatic activity. The two combined their expertise to create nanoparticle-protein complexes that, once injected, can reveal the presence of disease-related enzymes through a simple urine test.

Facebook’s Developer Circles are local communities designed to help developers learn and grow. For the 2019 Developer Circles Community Challenge, you are invited to build software applications that use at least one of three featured technologies: React360, Spark AR, and/or HTML5 Games. Your software must also fit into one of three categories: Gaming and Entertainment, Productivity and Utility, or Social Good.


Build software using React360, Spark AR, or HTML5 Games to give people the power to connect with friends and family, find communities and grow businesses.

SAN JOSE DEL GUAVIARE, COLOMBIA — Cerafín Méndez was out drinking one night when a fight broke out with his neighbor. The next day, three FARC soldiers came for him, bound his hands, and led him away.

That was the last time his family would see him alive.

“I was worried he had been left in the bush and eaten by animals, as if he were a dog,” said his wife, Miriam Méndez. “20 days passed, a month and nothing, nothing was found.”

Thirty years later, Méndez was finally given some closure when the Colombian government successfully identified her husband’s remains, and scheduled an event to bring them home for a proper burial.

“I finally feel like my mind was put to rest. Knowing his final location makes us feel less like he was abandoned alone,” Méndez’s daughter Mary told VICE News. “Before this, it was like he was forgotten in time.”

Méndez’s story isn’t uncommon in Colombia. More than 80,000 Colombians were violently disappeared at the hands of Guerrilla groups, armed gangs, and government forces during a half century of civil war. And for decades, their cases went cold, ignored or out of reach of authorities.

Optical microresonators convert laser light into ultrashort pulses travelling around the resonator’s circumference. These pulses, called “dissipative Kerr solitons,” can propagate in the microresonator maintaining their shape.

When solitons exit the , the output takes the form of a train—a series of repeating pulses with fixed intervals. In this case, the repetition rate of the pulses is determined by the microresonator size. Smaller sizes enable pulse trains with high repetition rates, reaching hundreds of gigahertz in frequency. These can be used to boost the performance of optical communication links or become a core technology for ultrafast LiDAR with sub-micron precision.

Exciting though it is, this technology suffers from what scientists call “light-bending losses”—loss of light caused by structural bends in its path. A well-known problem in , light-bending loss also means that the size of microresonators cannot drop below a few tens of microns. This therefore limits the maximum repetition rates we can achieve for pulses.

10.) Euhaplorchis Californiensis
The Euhaplorchis Californiensis is a parasite that is primarily found in southern California. These parasites live on the gut of shorebirds. Once the very tiny eggs of these parasites develop, they are released into the waters through the shorebirds’ feces. These eggs will live and develop into larva if they are swallowed up by snails.

9.) Acacia Trees
Ants and acacia trees have had a relationship for generations. For the longest time, people just assumed this is how it was and no one really looked into the reasoning for this relationship. That was until some scientists discovered that the relationship is actually more one sided than what people have previously thought.

8.) Phorid Flies

SEATTLE, Wash. — There were 2,275 bolts of lightning in Saturday’s lightning storm that shocked Puget Sound, according to the National Weather Service on Sunday.

“To have this much lightning in the lowlands is exceptionally rare,” said Reid Wolcott, Warning Coordination Meteorologist for the National Weather Service.
