After injecting poop bacteria into brain cancer patients' brains, doctors forced to resign - Boing Boing
Two neurosurgeons at UC Davis have resigned after infecting brain cancer patients with a pathogenic bacteria from their bowels in a last-ditch effort to halt progression of their cancers. The three patients gave their consent to Dr. J. Paul Muizelaar, 66, the former head of the neurosurgery department, and his colleague, Dr. Rudolph J. Schrot. But the doctors hadn't received OKs from the FDA, or school authorities, and the procedure hadn't even been tested on animals.
Detached octopus arms show awareness, react to danger | io9
After the animals were euthanized, their arms were removed and kept in chilled seawater for up to an hour until they were ready for experimentation. Some arms were suspended vertically, and others were laid out horizontally. When pinched, suspended arms recoiled from the unpleasant stimulus by shortening and curling in a corkscrew shape within one second. (After this, the arms slowly relaxed and returned to their previous length.) Tap water and acid applied to the arms evoked a similar response. Horizontal arms also moved away from the undesirable stimuli, many bending in a sort of contrived joint toward the top. “The results demonstrate that the arms are capable of reflex withdrawal to a ‘noxious’ stimulus without reference to the brain,” the researchers noted in their paper.
Drones Protect Peru's Cultural Treasures from Encroaching Development - Skift
Small drones have been helping a growing number of researchers produce three-dimensional models of Peruvian sites instead of the usual flat maps – and in days and weeks instead of months and years.
Speed is an important ally to archaeologists here. Peru’s economy has grown at an average annual clip of 6.5 percent over the past decade, and development pressures have surpassed looting as the main threat to the country’s cultural treasures, according to the government.
Researchers are still picking up the pieces after a pyramid near Lima, believed to have been built some 5,000 years ago by a fire-revering coastal society, was razed in July by construction firms. That same month, residents of a town near the pre-Incan ruins of Yanamarca reported that informal miners were damaging the three-story stone structures as they dug for quartz.
BBC News - Unlocking the secrets of the Elephant Man
The Elephant Man, Joseph Merrick, was an object of curiosity and ridicule throughout his life - studied, prodded and examined by the Victorian medical establishment. Now, 123 years after his death, scientists believe his bones contain secrets about his condition which could benefit medical science today.
BBC News - Huge canyon discovered under Greenland ice
One of the biggest canyons in the world has been found beneath the ice sheet that smothers most of Greenland.
The canyon - which is 800km long and up to 800m deep - was carved out by a great river more than four million years ago, before the ice arrived.
It was discovered by accident as scientists researching climate change mapped Greenland’s bedrock by radar.
Ancient Romans' Color-Changing Goblet Was Feat of Nanotechnology - D-brief | DiscoverMagazine.com
The mystery wasn’t solved until 1990, when researchers in England scrutinized broken fragments under a microscope and discovered that the Roman artisans were nanotechnology pioneers: They’d impregnated the glass with particles of silver and gold, ground down until they were as small as 50 nanometers in diameter, less than one-thousandth the size of a grain of table salt. The exact mixture of the precious metals suggests the Romans knew what they were doing—“an amazing feat,” says one of the researchers, archaeologist Ian Freestone of University College London.
