Everything in the Universe emits radiation, and the electromagnetic spectrum is a range of radiations with features in common, such as having electric and magnetic fields. Visible light forms part of the electromagnetic spectrum. So do emissions from TV and radio transmitters, mobile phones and the energy inside microwave ovens. The X-rays used in diagnostic imaging and the materials used in advanced positron emission tomography scanners (PET) also form part of this amazing range of radiations which share some features in common. Why electromagnetic? As the name implies, they have electric and magnetic fields associated with them. Although it is a bit complicated to demonstrate ...

Explosion on Jupiter spotted by amateur astronomers By Tariq Malik Video link (SPACE.com) An apparent impact on Jupiter early Monday (Sept. 10) created a fireball on the planet so large and bright that amateur astronomers on Earth spotted the flash. The surprising impact on Jupiter was first reported by amateur astronomer Dan Peterson of Racine, Wisc., who was observing the largest planet in our solar system when the event occurred, according to the website Spaceweather.com, which tracks space weather and night sky events. "It was a bright flash that lasted only 1.5 - 2 seconds," Peterson told Spaceweather.com. Peterson used a Meade 12-inch LX200GPS telescope to observe the ...

The Optical Ground Station, run by the European Space Agency on the Canary Island of Tenerife, was used to receive photons in a quantum teleportation experiment reported in September 2012. Physicists have "teleported" quantum information farther than ever in a new study reported Wednesday (Sept. 5). This kind of teleportation isn't quite what Scotty was "beaming up" on television's Star Trek, but it does represent a kind of magic of its own. While Star Trek's teleporters transport people from place to place instantaneously, quantum teleportation sends information. A team of scientists from Austria, Canada and Germany have now beamed the quantum state of ...

BERKELEY, Calif. (CBS Seattle) – It sounds like something out of the movie “Johnny Mnemonic,” but scientists have successfully been able to “hack” a brain with a device that’s easily available on the open market. Researchers from the University of California and University of Oxford in Geneva figured out a way to pluck sensitive information from a person’s head, such as PIN numbers and bank information. The scientists took an off-the-shelf Emotiv brain-computer interface, a device that costs around $299, which allows users to interact with their computers by thought. The scientists then sat their subjects in front of a computer screen and showed them ...

Too Much Protein HUWE1 Causes Intellectual Disability ScienceDaily (Aug. 30, 2012) — Two to three percent of children are born with an intellectual disability. Possibly by a genetic defect, but in 80 percent of these cases, we do not know -- yet -- which genes are responsible. VIB researchers at KU Leuven show that increased production of the HUWE1 protein is the cause in some patients. "The fact that HUWE1 regulates the dose of several other proteins in the brains, has an important impact on the quest for new therapies. It would then be possible to intervene in these different proteins. Research into the role of HUWE1 has already started in the lab." Defects on the ...

ScienceDaily (Aug. 30, 2012) — "Wisdom comes with winters," Oscar Wilde once said. And it's certainly comforting to think that aging benefits the mind, if not the body. But do we really get wiser as time passes? There are many way to define what exactly wisdom is, but previous literature suggests that having wisdom means that you are also good at resolving conflict. But conflict is not handled the same way across cultures. Americans have been shown to emphasize individuality and solve conflict in a direct manner, such as by using direct persuasion. In contrast, the Japanese place a greater emphasis on social cohesion, and tend to settle conflict more indirectly, ...

By DAVID MERCER Associated Press (AP:CHAMPAIGN, Ill.) Well driller Randy Gebke usually uses a geology database and other high-tech tools to figure out where to sink new water wells for clients. But if asked, he'll grab two wires, walk across the property, waiting for the wires to cross to find a place to drill. Gebke is water witching, using an ancient method with a greater connection to superstition than science. Thousands of wells have gone dry this summer in the worst drought the nation has experienced in decades. Some homeowners are spending as much as $30,000 to have new ones drilled, and Gebke said most potential customers in his area expect water witching to be part the deal. ...

The Republican Brain: The Science of Why They Deny Science—and Reality, Chris Mooney, 327 pages Chris Mooney believes conservatives are wrong about many more important issues than are liberals. Like any principled science writer, he’s also certain he could be wrong. Had Mooney chosen a less insulting title, he might have convinced a few conservatives to consider his positions on climate change, evolution, and President Obama’s healthcare program. Of course, he’d also sell fewer books. He and his publisher know their audience, just as Ann Coulter and Jonah Goldberg know theirs. Mooney admits that he has little hope of changing conservative minds through education. His 20 ...

This campion plant grew from a 32,000-year-old fruit.AP/Institute of Biophysics of the Russian Academy of Sciences Deep in the frozen tundra of northeastern Siberia, a squirrel buried fruits some 32,000 years ago from a plant that bore white flowers. This winter a team of Russian scientists announced that they had unearthed the fruit and brought tissue from it back to life. The fruits are about 30,000 years older than the Israeli date palm seed that previously held the record as the oldest tissue to give life to healthy plants. The researchers were studying ancient soil composition in an exposed Siberian riverbank in 1995 when they discovered the first of 70 fossilized Ice Age squirrel ...

Australian researchers have developed a sodium-ion-based battery which, they say, has the potential to solve one of sustainable energy’s greatest challenges – storing energy cheaply ‘offline’ after it has been generated. Dr Manickam Minakshi and Dr Danielle Meyrick from Western Australia’s Murdoch University point out that, while the efficiency of wind and solar technologies has improved rapidly, the problem of storage has yet to be solved. ‘The central obstacle facing sustainable energy is unreliability. Wind turbines don’t turn on a still day. Solar doesn’t work at night and can be hampered in the day by cloud, dust or snow coverage,’ Dr ...

Neil Armstrong, the first man to walk on the moon during the 1969 Apollo 11 mission, has died, following complications resulting from cardiovascular procedures. He was 82. Armstrong's words "That is one small step for (a) man, one giant leap for mankind," spoken on July 20, 1969, as he became the first person ever to step onto another planetary body, instantly became a part of history. Those few words from the Sea of Tranquillity were the climactic fulfillment of the efforts and hopes of millions of people and the expenditure of billions of dollars. A plaque on one of the lander's legs that concluded "We came in peace for all mankind," further emphasized that ...

BEIJING, Aug. 23 (Xinhua) -- Charles Bennett, winner of the 2012 Gruber Cosmology Prize, has devoted himself to the detection of new evidence for inflation, the theorized rapid expansion of the universe that occurred in the very first moments after its birth. "We don't know how to detect gravitational waves very well, but we can detect their impact - polarization," the 55-year-old astrophysicist from Johns Hopkins University said at the 28th General Assembly of the International Astronomical Union (IAU) held in Beijing from Aug. 20 to 31. The inflation theory postulates that the universe expanded far faster than the speed of light and grew exponentially almost ...
