While groundbreaking ideas such as quantum theory, relativity and even the Earth going around the Sun might be commonly accepted now, science still continues to show that the universe contains things you might find it difficult to believe, and even more difficult to get your head around. Theoretically, the lowest temperature that can be achieved is absolute zero, exactly ? 273.15°C, where the motion of all particles stops completely. However, you can never actually cool something to this temperature because, in quantum mechanics, every particle has a minimum energy, called “zero-point energy,” which you cannot get below.
Remarkably, this minimum energy doesn’t just apply to particles, but to any vacuum, whose energy is called “vacuum energy.” One prediction of Einstein’s theory of general relativity is that when a large object moves, it drags the space-time around it, causing nearby objects to be pulled along as well. 2008 / Juketube.
Test that can predict death - with a terrifying degree of accuracy. Click graphic to enlarge The test measures the average length of tiny structures on the tips of chromosomes called telomeres which are known to get shorter each time a cell divides during an organism’s lifetime. Telomeres are believed to act like internal clocks by providing a more accurate estimate of a person’s true biological age rather than their actual chronological age. This has led some experts to suggest that telomere tests could be used to estimate not only how fast someone is ageing, but possibly how long they have left to live if they die of natural causes.
Telomere tests have been widely used on experimental animals and at least one company is offering a £400 blood test in the UK for people interested in seeing how fast they are ageing based on their average telomere length. Now scientists have performed telomere tests on an isolated population of songbirds living on an island in the Seychelles and found that the test does indeed accurately predict an animal’s likely lifespan. Popular Science - A Nerd's Guide to Reading. How can parts of Canada be 'missing' gravity?" For more than 40 years, scientists have tried to figure out what's causing large parts of Canada, particularly the Hudson Bay region, to be "missing" gravity. In other words, gravity in the Hudson Bay area and surrounding regions is lower than it is in other parts of the world, a phenomenon first identified in the 1960s when the Earth's global gravity fields were being charted.
Two theories have been proposed to account for this anomaly. But before we go over them, it's important to first consider what creates gravity. At a basic level, gravity is proportional to mass. So when the mass of an area is somehow made smaller, gravity is made smaller. Gravity can vary on different parts of the Earth. One theory centers on a process known as convection occurring in the Earth's mantle. A new theory to account for the Hudson Bay area's missing gravity concerns the Laurentide Ice Sheet, which covered much of present-day Canada and the northern United States.
So which theory is correct? Saturn's moon Enceladus holds promise of alien life. By Robin McKie, The ObserverSunday, July 29, 2012 17:21 EDT Enceladus is little bigger than a lump of rock and has appeared, until recently, as a mere pinprick of light in astronomers’ telescopes. Yet Saturn’s tiny moon has suddenly become a major attraction for scientists. Many now believe it offers the best hope we have of discovering life on another world inside our solar system. The idea that a moon a mere 310 miles in diameter, orbiting in deep, cold space, 1bn miles from the sun, could provide a home for alien lifeforms may seem extraordinary.
Nevertheless, a growing number of researchers consider this is a real prospect and argue that Enceladus should be rated a top priority for future space missions. This point is endorsed by astrobiologist Professor Charles Cockell of Edinburgh University. “It just about ticks every box you have when it comes to looking for life on another world,” says Nasa astrobiologist Chris McKay. Equally remarkable is the impact of this water on Saturn. Best layman's explanation for Scientific Theory I have ever seen. Earth From Space. Scientists twist light to send data: Beams of light can be twisted and combined to transmit data dramatically faster. A multi-national team led by USC with researchers hailing from the U.S., China, Pakistan and Israel has developed a system of transmitting data using twisted beams of light at ultra-high speeds -- up to 2.56 terabits per second.
To put that in perspective, broadband cable (which you probably used to download this) supports up to about 30 megabits per second. The twisted-light system transmits more than 85,000 times more data per second. Their work might be used to build high-speed satellite communication links, short free-space terrestrial links, or potentially be adapted for use in the fiber optic cables that are used by some Internet service providers. "You're able to do things with light that you can't do with electricity," said Alan Willner, electrical engineering professor at the USC Viterbi School of Engineering and the corresponding author of an article about the research that was published in Nature Photonics on June 24.

What the Hell is it Used For? In addition to making screens that can be rolled up and stuck in our back pocket, a lot of scientists and doctors want to use elastic conductors to make flexible-lensed cameras... to be fitted to the back of the eyeball. A non-Newtonian liquid, in practical terms, is a liquid that turns solid when sufficient stress is applied. Also, something with lasers.

An incandescent light bulb recognized by Guinness World Records as being the longest burning is still glowing strong days after celebrations that marked its 110th anniversary. The Centennial Light Bulb, at Fire Station No. 6 in Livermore, Calif., has been burning bright since it was first installed in 1901. (The exact date appears unknown, though the bulb’s “birthday” is typically held in June, most recently June 18th.) Since then, the 60-watt bulb has been alight 24 hours a day, operating at about 4 watts, to provide night illumination of the fire engines.
Other than a few power outages, there has only been one break in its operation, when it was removed from one fire station and fitted in another in 1976. The cord was severed out of fear that unscrewing the bulb would break it, and it was moved with a full police and fire truck escort, under the watch of Capt.

Therapy Fixes Color Blindness in Monkeys. Monkeys once color-blind can now see the world in full color thanks to gene therapy. The results demonstrate the potential for such methods to eventually cure human vision disorders, from color blindness to possibly other conditions leading to full blindness.
The primate patients, named Dalton and Sam, are two adult, male squirrel monkeys that were red-green color-blind since birth — a condition that similarly affects human males more than females. Five months after researchers injected human genes into the monkeys' eyes, the duo could see red as if they had always had this ability. Since human genes were used and the monkeys' eyes and brains are similar to ours, at least in terms of color vision, the researchers hope the same procedure could work in humans.
"People who are color-blind feel that they are missing out," said study researcher Jay Neitz, a professor of ophthalmology at the University of Washington, Seattle. Color-coded Like humans, monkeys' eyes contain cone and rod cells. What Are The Odds? Geek image scares women away from tech industry. High performance access to file storage Women don't consider IT careers because “the popular media’s ‘geek’ image of the technology field” along with other factors including a lack of female role models and support at home and work “tend to dissuade talented girls from pursuing a tech career.”
“Misguided school-age career counselling” is another problem, as it often suggests to young women that ICT careers are too hard or somehow unfeminine. That's the conclusion of a “high-level dialogue” hosted by the International Telecommunication Union (ITU) in New York yesterday. The event was staged on Girls in IT Day, an annual United Nations day to promote careers in technology for women. Girls in IT Day events were staged in more than 70 countries. In his welcoming remarks, ITU Secretary-General Dr Hamadoun Touré said that the ICT industries need women. “Over the coming decade, there are expected to be two million more ICT jobs than there are professionals to fill them,” he said.

MIT Creates New Energy Source. This is some pretty exciting news. It seems that researchers at the Massachusetts Institute of Technology (MIT), one of the most prestigious science and engineering schools in the United States, has created a new energy source -- and it's clean and renewable. The odd thing is that the only way you can see this energy source is with a very powerful microscope, because it is created by using nanotechnology. For a few years now, we have been hearing about the possibilities offered by the new field of nanotechnology.
Now it looks like the first usable breakthrough has been accomplished. MIT has devised a process to generate electricity using nanotechnology. The researchers built tiny wires out of carbon nanotubes. The nanotechnology batteries will have a couple of other advantages over current batteries. Second, these batteries are non-toxic since they are made of carbon. Computers, cell phones and other electronic devices will be the first to benefit from the nanotechnology batteries.

Why Humans Are So Smart…and Groovy. Grooved fingers make us smart. ...as do grooved brains. When you are next in the shower, take a look at your wrinkled fingers. They aren't pretty to look at, but they help make you smart. Pruney fingers are not an accidental side effect of getting soaked as is typically believed, but are, instead, highly efficient rain treads that help us primates grip the world when it is wet ( something we've recently been studying in the lab ).
Without wrinkled fingers you would need to possess two categories of behavior, one for dry conditions, and one for wet. That would require more brain space than you can spare. Lucky for you, you can get by with just one set of behaviors ("all-weather-behaviors") because your fingertips and feet "know" when to change from race-tire-smooth to rain-tire-wrinkled. The strategy of "subcontracting" out brain responsibilities to low-brow reflex-like mechanisms is one of the oldest tricks in evolution's book. We humans are different.

Pythagorean cup. Cross section Cross section of a Pythagorean cup. A Pythagorean cup (also known as a Pythagoras cup, a Greedy Cup or a Tantalus cup) is a form of drinking cup that forces its user to imbibe only in moderation.
Credited to Pythagoras of Samos, it allows the user to fill the cup with wine up to a certain level. If he fills the cup only to that level, the imbiber may enjoy a drink in peace. If he exhibits gluttony, however, the cup spills its entire contents out of the bottom (onto the lap of the immodest drinker).[1] Form and function[edit] A Pythagorean cup looks like a normal drinking cup, except that the bowl has a central column in it – giving it a shape like a Bundt pan in the center of the cup. When the cup is filled, liquid rises through the second pipe up to the chamber at the top of the central column, following Pascal's principle of communicating vessels.
