What's all the jubilation about? Well, for one of the last people who touched the little spaceship's battery before it left the earth in 2011, it's a time for joyous celebration. That would be Mike Surline, a guy who knows batteries.

I've often thought it interesting that when SETI scientists imagine extraterrestrial civilizations, they usually think in terms of unified worlds that have one civilization. The image is very much unlike our world, in which we have multiple civilizations that are fractured and in conflict with other societies. The Brexit event...

With the Paris Agreement leaving it up to the governments of individual countries to determine their own emission reduction targets, it is clear that the only way those targets will ever improve is if we - the citizens of those countries - insist to our governments that they do so.

In early May, a rapid, low-cost, freeze-dried, paper-based, strain-specific diagnostic system for detection of the Zika virus was introduced by an international consortium of researchers led by synthetic biologist James Collins of Harvard's Wyss Institute for Biologically Inspired Engineering. It could soon be used in the field to screen blood, urine or saliva samples.

Newborns sleep about 16 hours a day, but as they age they develop a homeostatic mechanism that balances their increasing ability to stay awake and their ongoing need for sleep. The circadian rhythm of sunlight and darkness helps to drive one part of this mechanism.
We can't erase memories yet. But our lab is working on a new tool that could lessen the emotional impact of burdening memories by targeting them during sleep.
We are going through a profound change in the way we think, called the cognitive revolution. Over the last hundred years our lives have become ever more dominated by the need to think in abstract terms and categorize objects scientifically. The doubling and quadrupling of knowledge, or at least data,...
Since ancient times, compounds containing mercury have been used in the treatment of skin diseases and other ailments. However, mercury toxicity was not fully appreciated until March 8, 1809 when two British ships, the HMS Triumph and HMS Phipps, came to the rescue of a Spanish ship that had been damaged in a hurricane. They rescued the crews and transferred the valuable cargo of mercury. Within weeks, the crews began to experience the effects of mercury poisoning, eventually many were hospitalized and some died. Mercury was known to ancient peoples and was even found adorning a 15th century BCE ceremonial cup in an Egyptian tomb. Aristotle authored the earliest record of what he called "fluid silver" or quicksilver in the 4th Century BCE. Mercuric chloride, calomel, was used as an antiseptic to kill bacteria while mercuric sulfide is used to make the bright red vermillion paint. Mercury was also commonly used in batteries, fluorescent lights, thermometers, barometers and felt production leading to dementia in those workers and the phrase "mad hatters" coined by Lewis Carroll in Alice in Wonderland. Mercury has been used to extract gold and silver by a process of amalgamation. The Spanish ship was transporting mercury to South America for the extraction of silver. On March 16th some of the mercury was transferred into the sloop HMS Phipps. The cargo had been saturated with water leading to rotting containers with several tons of mercury leaking into the lower decks and holds of both ships. Mercury quickly contaminated everything on the lower decks. Within 3 weeks, mercury poisoning appeared among the crews. Symptoms of mercury poisoning were excessive saliva secretion, mouth ulcerations, and partial paralysis as well as lung and bowel complaints. At an estimated temperature below decks of 68 degrees F, the saturation point of mercury would have been 140 times the maximum allowable concentration. Those with the highest exposure, some of whom later died, suffered from dramatic swelling of their heads and tongues, lost their teeth and suffered from gangrene of the face and tongue. By mid-April, 200 men, one third of the crew, showed signs of mercury poisoning. On April 22nd, the men were transferred to hospital ships and the Triumph was inspected by four fleet surgeons. The Triumph was a large 79 gun ship of the line. The very different structure of the sloop HMS Phipps lessened the impact of mercury on board, though some of her sailors were also affected. The Triumph was cleaned and returned to service in June only to have fresh cases of mercury poisoning appear. By June 13th, she was ordered to sail home to England which took 40 days and despite numerous precautions, additional men became ill, but the symptoms were not as severe. The Triumph was emptied and little is known about her fate other than she became a quarantine ship before being broken up in 1850. Though poisoning with mercury was known, accidental poisoning by mercury vapor was rare and the incident on the Triumph is unique in the history of toxicology. It gave everyone a fuller appreciation for the dangers of mercury poisoning.
