Giant Cosmic Space Clouds of Beer Every now and then you hear something which grabs your attention. This captured my attention: There is a cloud of alcohol (ethyl alcohol – the happy juice found in beer, wine, and spirits) floating in space. This isn’t a small cloud either. There is enough alcohol in this cloud to make fill 400 trillion trillion pints of beer.
How Many Dimensions Does the Universe Really Have? An engineer, a mathematician and a physicist walk into a universe. How many dimensions do they find?
Charles Wenzel August 5, 2005 Gubs are those round, black spots you see on the pavement and sidewalks outside most public establishments, especially gas stations and restaurants. You may have seen thousands of them but never realized what they are or even noticed them. Once you do, your world will never be as clean; some establishments have thousands of gubs on the ground in the immediate vicinity of the door. Gubs
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.

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. In developing the VoiceDraw application, we worked with an "electronic voice painter" named Philip Chavez who has had a spinal cord injury for over 30 years and had been creating artwork using his computer and a speech recognition software for over 15 years. A short video documentary featuring the artist and a mention of our VoiceDraw application can be viewed at this link.

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.

Most animals have a daily pattern of rest and activity. 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:

Nature's game of intimidation and imitation comes full circle in the waters of Indonesia, where scientists have recorded for the first time an association between the black-marble jawfish (Stalix cf. histrio) and the mimic octopus (Thaumoctopus mimicus). Undescribed by scientists until 1998, the talented mimic octopus is known to impersonate toxic flatfish, lionfish, and even sea snakes by creatively configuring its limbs, adopting characteristic undulating movements, and displaying bold brown-and-white color patterns. Thanks to these brazen habits, it can swim in the open with relatively little fear of predators. Fish mimics octopus that mimics fish
It's something you would never expect to go missing, but one of the world's brightest glow-in-the-dark mushrooms has been rediscovered after an absence of more than 170 years, according to USA Today. The bioluminescent shrooms had become a Brazilian legend of sorts. They were first spied in 1840 by an English botanist named George Gardner, who was alarmed after he saw some boys playing with a glowing object in the streets of Vila de Natividad, a village in the Goiás state in central Brazil. After that, no more sightings of the brightly glowing fungus had ever been reported. The mushroom was nearly forgotten until 2002, when Brazilian chemist Cassius Stevani came across Gardner's early reports. Then, in 2005, a breakthrough occurred.
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. Faster-than-light neutrinos could be proof of extra dimensions
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.
