One hundred years ago, Einstein re-envisioned space and time as a rippling, twisting, flexible fabric called spacetime. His theory of general relativity showed how matter and... Read Full Post From Nature of Reality | Sep 28, 2015.

Energy. Butterfly wings feel the heat › News in Science (ABC Science) News in Science Monday, 13 February 2012 Stuart GaryABC Lepidoptric imaging Scientists are using a five million year old design to make a better infrared detector.
Dr Radislav Potyrailo and colleagues at General Electric in the United States are copying the microscopic structures found on the scales of butterfly wings to develop new technology with medical, industrial and military applications. The future of space with Bill Nye, Neil deGrasse Tyson, Pamela Gay, and Lawrence Krauss discuss our future in space.

Note the snake's girth and head size relative to the size of the men holding her carcass. VoiceDraw. VoiceDraw is a drawing program designed to be controlled using only one's voice.
Since no mouse, keyboard or stylus is required, it can be used by people with various forms of motor impairments to express themselves creatively. VoiceDraw is built upon the Vocal Joystick engine in order to process "non-linguistic vocal parameters" in addition to traditional speech recognition for providing continuous and fluid control of the virtual brush. Non-linguistic vocal parameters are voice features that do not correspond to a particular word or phrase in a language, such as changes in loudness, pitch, and vowel quality. Your Brain On Psilocybin Might Be Less Depressed : Shots - Health Blog. Hide captionThis could be your forest on psilocybin.
Baxterclaus/Flickr This could be your forest on psilocybin. Magic mushrooms are said to blow your mind, but the hallucinogenic chemical psilocybin, the active ingredient, actually reins in key parts of the brain, according to two new studies. The memorably vivid emotional experiences reported by mushroom users may flourish because the parts of the brain suppressed by psilocybin usually keep our world view tidy and rational. And since the brain area affected by psilocybin can also be out of whack in mental health problems such as depression, the researchers speculate that the drug may turn out to be useful in treating mental illness.
Some animals are more active during the day (diurnal) and some are more active during the night (nocturnal). How much time do animals spend sleeping? Well, it depends on the animal: References: This table was adapted from four sources: Aserinsky, E., Eyelid condition at birth: relationship to adult mammalian sleep-waking patterns, In Rapid Eye Movement Sleep, edited by B.N.

Faster-than-light neutrinos could be proof of extra dimensions. Similarly, how can I get my ice cream scoops to jump between flavours and manipulate them?
Because my wife is always buying Chocolate, but I prefer Strawberry and would like it to be in the shape of a bunny rabbit. Three main issues I see with that. First, neutrinos fluctuate seemingly at random. The type is also created at random.

An Alcubierre Warp Drive stretches spacetime in a wave causing the fabric of space ahead of a spacecraft to contract and the space behind it to expand.
The ship can ride the wave to accelerate to high speeds and time travel. The Alcubierre drive, also known as the Alcubierre metric or Warp Drive, is a mathematical model of a spacetime exhibiting features reminiscent of the fictional "warp drive" from Star Trek, which can travel "faster than light" (although not in a local sense - see below). The key characteristics of the application of Alcubierre warp drives for time control and time travel are presented in the picture below. This is followed by more detail describing the effect below.
