Say Goodbye to Fillings

There’s not a whole lot to like about fillings, what with the prodding, scraping and jabbing and all. And that’s before the drill even comes out (followed by the bill at the end). Tending to our cavities might one day be a much more comfortable experience, with scientists discovering that a type of Alzheimer’s drug can actually stimulate stem cells within the tooth pulp to promote natural repair instead.

The drug in question is a small molecule called a glycogen synthase kinase (GSK-3) inhibitor. read more

In 1996, scientists discovered what may be the strangest stone ever found, in an equally strange section of the Sahara desert that’s littered with unique yellow glass. Nicknamed the Hypatia stone, the relic was later found to be extraterrestrial in origin, but was unlike any known kind of meteorite or comet. A new study has deepened the mystery even further, finding that Hypatia could predate the formation of the Solar System, or have interstellar origins. read more

Lobsters are the Key To Jellyfish Blooms

Jellyfish blooms are regarded by some as an ecological menace, but they may sound the dinner gong for the commercially valuable Norway lobster. Recently, a team of scientists from Heriot-Watt University in Edinburgh have photographed the tasty crustacean in the waters off western Norway chowing down on jellyfish carcasses, suggesting that they could form a major part of its diet.

The 25-cm (10-in) Norway lobster (Nephrops norvegicus), also known as the Dublin Bay prawn, langoustine, or scampi, is the most important commercial crustacean in Europe, responsible for revenues of £78 million (US$105 million) to Scotland alone. They’re remarkably abundant in the north-eastern Atlantic and parts of the Mediterranean, and they’re cheaper than the larger common lobster. Each year 60,000 tonnes of them are hauled in with half taken in British waters. read more

5,000 Year Old Murder

A scientist has finally confirmed with 3D models that legendary ice man Otzi was indeed killed 5,300 years ago by an arrow.

Otzi, a 5,300-year-old mummified man, was found in 1991 in a glacier in the Alps between what is now Austria and Italy.

Since the discovery, Otzi has been examined by multiple teams of scientists, with new discoveries coming to light each time.

Now an expert claims it was the arrow that delivered the fatal blow, severing the nerve to his shoulder and hitting his major vessels.

There are already skin patches that help people quit smoking … could patches that help them lose weight be far behind? Well, thanks to research being conducted at Singapore’s Nanyang Technological University, the things already exist – for mice, at least. read more

Currently, post traumatic stress disorder (PTSD) is usually treated with psychotherapy and antidepressants, but with the variability of the human mind those aren’t always effective. Now a study conducted at Wake Forest Baptist Medical Center has found that a novel form of treatment reduced symptoms of the disorder by effectively letting patients “hear” their own brainwaves. read more

Cardboard Delivery Drone

Once the goods have arrived, the drones biodegrade in a matter of days

In developing regions where lack of road infrastructure is problematic for those in the business of moving goods, drones are already having an impact. But also problematic is the fact that the people sending drones off to do the courier work kinda need them back again. A new cardboard drone being funded by DARPA won’t concern itself with such limitations, with the ability to deliver vital goods and disappear soon after the job is done.
