With their often high-sugar diets and lax brushing habits, many children are particularly susceptible to cavities. An experimental new treatment could help, however, using enzymes to weaken the plaque that forms on the teeth.

Once it's been injured, the protective cartilage in our knees and other joints heals very slowly – if at all. A new injectable gel, however, could both reinforce the tissue after it's been damaged, and encourage new cartilage to grow over top of it.

Seventy five years ago, the world was introduced to ENIAC, the first ever electronic, programmable, general purpose, digital computer, which not only ushered in the beginning of the computer age, but also shaped popular conceptions of the computer.

Osteoarthritis is a painful and fairly common condition that’s hard to slow, so treatment options are mostly limited to reducing pain. But a new study in mice has now found that nanotherapeutic injections into the knee can slow cartilage degradation.

Antibiotic-resistant bacteria are poised to become a huge health problem, and we desperately need new treatments. Now, researchers have engineered new antimicrobial molecules from wasp venom, which have shown promise in tests in mice.
-
University of Pennsylvania scientists have demonstrated how a glowing dye can be used to light up cancer cells in tumors and the lymph nodes of dogs, which they say offers hope for improved surgical outcomes in humans.

The Mars Helicopter drone may be scheduled to launch soon, but it's still just a single aircraft that will be useless if it conks out. With that in mind, scientists are now looking into an alternative – fleets of tiny, cheap "Nanocardboard Flyers."
-
As electronic devices shrink batteries are becoming too heavy and inefficient for some uses. Now, researchers at the University of Pennsylvania have developed a new type of robot that powers itself by “eating” metal from its environment.

Made famous in the movie Jurassic Park, the raptor dinosaurs are scientifically known as the dromaeosaurids. A newly-discovered member has recently been added the group, and it was likely one of the last raptors to exist.
-
A link between diseases such as Alzheimer’s and sleep loss has been frequently cited, and a new study has now discovered a signaling pathway that both regulates sleep and controls the protein aggregations commonly associated with neurodegeneration.
-
Well over 100 new minor planets have been discovered in our solar system, in the darkness out beyond the orbit of Neptune. The discoveries were made by sifting through several years’ worth of data gathered by the Dark Energy Survey (DES).

New research has analyzed hundreds of brain scans from patients with schizophrenia revealing two distinct subtypes with differences in gray matter volumes, busting the previously held notion that all schizophrenia patients' brains are the same.
