A new tooth-regenerating paste could reverse bacterial-induced tooth decay, sweeping dental drills into the dustbin of history. Hopefully.
As your hygienist probably told you, tooth decay happens when bacteria in plaque dissolve your enamel, creating cavities. Eventually the cavity gets big enough that your dentist has to take out the decay and drill a hole that can be filled with resin, gold or something else. But a new treatment developed at the University of Leeds in the UK reverses the decay, allowing your teeth to rebuild themselves.
Something to reflect on over your lunch break today: Scientists are developing a new approach for producing human-derived gelatin in large enough quantities to be a commercially viable replacement for the animal-based gelatins used in all kinds of gelatin-like desserts, candies, and other foodstuffs as well as pharmaceuticals and cosmetics. Think about that next time you crack open a mid-afternoon pudding snack.
Most glues become brittle and lost their stickiness when moisture is removed, but a new peptide-based adhesive developed at Kansas State University does the exact opposite, becoming stickier in drier environments. While that may not mean much for those living in a swamp, this unique property could make adhering objects in outer space a whole lot easier.
Some of the greatest discoveries in science have been total accidents — Alexander Fleming's use of penicillin, Wilson and Penzias' discovery of the cosmic microwave background, etc. Today, scientists announced they've once again unintentionally made a monumental discovery: A cure for baldness. OK, only in mice.
Still, the finding — involving a chemical compound that blocks a stress hormone — could lead to human hair loss treatments, the scientists say. The researchers have applied for a patent on the use of the compound for hair growth.
As bacteria grow increasingly resistant to antibiotics, a synthetic molecule may be our best chance at fighting back

Humans are in an escalating battle with bacterial infections. Our last lines of antibiotic defense are increasingly becoming our only lines. Bacteria have demonstrated an adept ability to mutate and foil drugs at a pace which nearly bests our research and development efforts. However, a new class of molecules recently synthesized by researchers at Stanford University is
showing early promise in fighting off infection in a manner unlike any other.
