Since 1944, physicists at Trinity College in Dublin have been trying to measure the viscosity of pitch tar, a polymer seemingly solid at room temperature, and witness it dripping from a funnel.

"The viscosity of pitch-tar is calculated to be 230 billion times that of water or 230,000 times the viscosity of honey," the college's School of Physics says on the experiment page.

Pigeons -- the rats of the winged world -- have shown an aptitude for using touchscreens to carry out an intelligence test, according to psychology research from the University of Iowa.

When the birds pecked the correct button on the screen, the virtual bowl would move a bit closer. After continually pecking at the button connected to the virtual food, the birds would be rewarded with a real edible treat.

The 10,000-year-old beast was found on one of the Lyakhovsky Islands in the Novosibirsk archipelago off the northern coast of Siberia. Researchers from the Northeastern Federal University in Yakutsk poked the remains with an ice pick and, incredibly, blood flowed out.

In September 2012 reports came in that remains with "living" cells had been found by Grigoriev and his team elsewhere in Siberia, but the excitement soon dissipated when it became clear that a translation error had made the discovery seem more impressive than it was.

A teenage girl puts two household chemicals in a water bottle at school to see what might happen. There is a small explosion. No one is hurt. She is expelled and charged with weapons possession.

The top of the bottle popped off and there was some smoke. No one was hurt.

So, despite the fact that Wilmot reportedly told police this was nothing more than the experimentation of a curious mind, she was taken to a juvenile detention center and may now be labeled a felon.

Some people can boast a green thumb, but very few people can boast a glowing green thumb. For a pledge of $40, Glowing Plants will send you 50 to 100 seeds to let you raise your own glowing plant at home.

While prototype glowing plants have been created, there's a chance that this first round of Kickstarter plants may not glow quite as much as people would like. "We hope to have a plant which you can visibly see in the dark (like glow in the dark paint) but don't expect to replace your light bulbs with version 1.0," the teams says.

Jeffrey P. Khan writes in the NY Times that recent anthropological research suggests that human's angst of anxiety and depression ultimately results from our transformation, over tens of thousands of years, from biologically shaped, almost herd-like prehistoric tribes, to rational and independent individuals in modern civilization and that the catalyst for suppressing the rigid social codes that kept our clans safe and alive was fermented fruit or grain.

Examining potential beer-brewing tools in archaeological remains from the Natufian culture in the Eastern Mediterranean, the team concludes that 'brewing of beer was an important aspect of feasting and society in the Late Epipaleolithic' era.

Sausages, ham, bacon and other processed meats appear to increase the risk of dying young, a study of half a million people across Europe suggests.

She said if everyone in the study consumed no more than 20g of processed meat a day then 3% of the premature deaths could have been prevented.

"For most people there's no need to cut back on fresh, red meat. For people who have very high intake of red meat - eat lots of red meat every day - there is the recommendation that they should moderate their intake," she added.

A baby girl in the US born with HIV appears to have been cured after very early treatment with standard drug therapy, researchers say.

It suggests the treatment wiped out HIV before it could form hideouts in the body.

These so-called reservoirs of dormant cells usually rapidly re-infect anyone who stops medication, said Dr Persaud.

CERN has revealed that the world's largest and most powerful atom smasher – the Large Hadron Collider (LHC) is going into hibernation and will be shut down for a period of two years for upgrade purposes.

Gillies told AFP on Friday that the shutdown will enable engineers to lay superconducting cables in huge numbers thereby bringing the machine up to "full design energy."

The fourth annual Maker Faire debuted the 14-and-15 year-old girls' invention. The generator provides six hours of electricity with a liter of urine.

The electrolysis of urea that will generate the hydrogen requires an electrical input. Therefore, the urine cannot be used to create electricity in areas that do not have an existing power supply.
