Scientists have detected water vapor on other planets in the past, but these detections could only take place under very specific circumstances. The new technique expands a radial velocity technique, commonly used to detect carbon dioxide using light in the visible spectrum, into the infrared spectrum. This has opened up the ability of astronomers to analyze the molecules that comprise the atmosphere of exoplanets that don't exist under those specific circumstances.

Keck Observatory have developed a new technique for planetary scientists that could provide insight into how many water planets like Earth exist within our universe.
A bacterium normally responsible for human acne, has been found clustered in grape vines. In this striking case of pathogen transfer, the bacterium has been found colonizing bark tissues, and the pith, where the bacterium can localize intracellularly.
In a striking case of pathogen transfer involving the bacteria responsible for human acne, P. acnes, authors Campisano, et. al., report in the journal Molecular Biology and Evolution on a new type of P. acnes which exploits grapevines, dubbing it P. acnes type Zappae.
Canadian astrophysicist Niayesh Afshordi and his colleagues have turned to an idea first proposed 13 years ago. In that model, our 3D universe is merely a membrane- also known as a brane- floating through a 4D “bulk universe.”
There could be a gaping hole in the Big Bang theory. Or rather, a giant, colossal black-hole caused by the collapse of a four-dimensional star. One of the main problems with the Big Bang is that the temperature of the universe is nearly uniform.
There’s been disagreement over precisely what caused Chris McCandless’s death, but new evidence assembled by curious writer and then chronicled by Into the Wild author Jon Krakauer points a likely final verdict: poisoning from a toxin unknown to be in the wild potato seeds he consumed, which led to McCandless’s weakening, paralysis, and starvation.
As with Aron Ralston, the story of Chris McCandless has sharply divided observers, between those who see him as a hero for eschewing a materialistic, traditional western life and those who think he was an idiot who got in over his head and then paid the ultimate price in the Alaskan bush.
While researchers at Duke University have demonstrated brain-to-brain communication between two rats, and Harvard researchers have demonstrated it between a human and a rat, researchers at the University of Washington believe this is the first demonstration of human-to-human brain interfacing.
University of Washington researchers have performed what they believe is the first noninvasive human-to-human brain interface, with one researcher able to send a brain signal via the Internet to control the hand motions of a fellow researcher.
