An unexpected discovery has led scientists to open an intriguing new window into the human brain, via the visual system. Their finding may have implications for better understanding of states such as sleep, epilepsy and anaesthesia say the research team leaders Dr Sam Solomon and Professor Paul Martin of The Vision Centre and The University of Sydney. Potentially it could open up a new pathway for manipulating brain rhythms to manage disorders such as insomnia and epilepsy, the team speculate in an article published today in the Proceedings of the National Academy of Sciences of the USA. “It was purely a chance observation we made while we were activating the three cell layers of ...

In recent years, former Vice President Al Gore has been the object of a great deal of humor — and ire — for his extremist views and hypocritical actions when it comes to the environment. But a bizarre rant from the man who was once heartbeats away from becoming President of these United States calls forth a term which Americans want nowhere near the Oval Office: unhinged. The ideology of manmade global warming has fallen on hard times in recent years due to a series of revelations that have fundamentally undermined the credibility of the “science” and its advocates. Beginning with “Climategate” and “Glaciergate” and continuing through such public ...

The death of the Sun to be accompanied with gigantic fireworks. 45090.jpegThe long-anticipated and widely discussed doomsday will come, but it is going to happen in approximately five billion years. The core of the Sun will run out of hydrogen by this time, and our celestial body will turn into a red giant. The star will then gradually turn into a white dwarf - the core of the Sun. Scientists from the University of Cambridge have recently presented the computer model of this process. When scientists say that the Sun can explode, common people mostly take such forecasts as absurdity. However, the Sun is not eternal. The Universe is not stable at all, and any of its bodies, including stars, ...
How cancer cells metastasize

Scientists have discovered how cancerous cells can "elbow" their way out of tumours, offering clues for new drugs to prevent cancers spreading. They say they have identified a protein called JAK which helps cancerous cells generate the force needed to move. Writing in Cancer Cell, they say the cells contract like muscle to force their way out and around the body. Cancer Research UK said the study provided fresh understanding of ways to stop cancer spreading. When cancers spread, a process known as metastasis, they become more difficult to treat, as secondary tumours tend to be more aggressive. It is thought that 90% of cancer-related deaths occur after metastasis. JAK attack ...

Scientists have discovered a natural preservative substance that keeps food fresh for years by destroying different food rotting bacteria. The agent called bisin is produced by harmless bacteria and has the capability of destroying a whole class of food decomposing germs including E-coli, salmonella and listeria. A team of researchers led by Dr. Dan O'Sullivan, an Irish microbiologist working with the University of Minnesota, isolated the substance from a culture of Bifodobacterium longum, a harmless bacterium commonly found in the human gut. The researchers claim that bisin can extend the life of many daily foods which have strict use-by dates including seafood, meat, eggs, dairy ...

Open source unemployment. Here is a very serious thought. As far as we know few people have written about it. Few have even thought about it. And no one has figured out what it means. But it could mean that the whole nature of the economy...and how we measure it...will have to change. More immediately, it is another cigarette for the wheezing Middle Class. The seed was planted by a headline from the Wall Street Journal. We didn't read the article. But we noticed the headline. "Porn industry profits down," or something like that. Hmmm.... surely, the demand had not decreased. We began to think about why the porn industry might be less profitable. We'll take a guess -- ...

Looking to nature for their muse, researchers have used a common protein to guide the design of a material that can make energy-storing hydrogen gas. The synthetic material works 10 times faster than the original protein found in water-dwelling microbes, the researchers report in the August 12 issue of the journal Science, clocking in at 100,000 molecules of hydrogen gas every second. This step is just one part of a series of reactions to split water and make hydrogen gas, but the researchers say the result shows they can learn from nature how to control those reactions to make durable synthetic catalysts for energy storage, such as in fuel cells. In addition, the natural protein, an ...

Contact lost with hypersonic glider after launch By JOHN ANTCZAK Associated Press LOS ANGELES (AP) -- An unmanned hypersonic glider developed for U.S. defense research into super-fast global strike capability was launched atop a rocket early Thursday but contact was lost after the experimental craft began flying on its own, the Defense Advanced Research Projects Agency said. There was no immediate information on how much of the mission's goals were achieved. It was the second of two planned flights of a Falcon Hypersonic Technology Vehicle-2. Contact was also lost during the first mission. The small craft is part of a U.S. military initiative to develop technology to respond to ...
"Super" mouse evolves resistance to most poisons

Scientists say that some European house mice have developed resistance to the strongest poisons. German and Spanish mice have rapidly evolved the trait by breeding with an Algerian species from which they have been separate for over a million years. The researchers say this type of gene transfer between different species is highly unusual and normally found in plants and bacteria. They are concerned that this rare form of rapid evolution could herald the spread of new generations of rodents resistant to almost any form of chemical pest control. Warfarin is a drug widely used in medicine as an anticoagulant to prevent the build up of harmful blood clots. It works through inhibiting a ...

Like most forms of renewable energy, solar power still loses points for cost effectiveness. Two Swiss energy pioneers hope to change that with a blow-up solution. Felix Tiefenbacher and Samuel Kutter of Vienna-based Heliovis have seen the future and the future is sausage shaped and inflatable. The prototype is impressive: a 35-metre long tube, two metres in diameter. The final 200-metre long device is due on the market in 2016. The solar innovators have permission to assemble and test their device on the grounds of the Dürnrohr steam power plant near Zwentendorf in Austria. Swissinfo.ch went along for a physics lesson. Tiefenbacher is pleased and annoyed in equal parts. On the plus ...

Researchers at Taiwan's Industrial Technology Research Institute are developing a new kind of electronic paper that's as promising as its name is spectacularly un-catchy. Dubbed "i2R e-Paper" by its developers, it's coated with a compound that can be erased, reproduces different colors, and doesn't need a backlight to print, according to Reuters. "I think the greatest breakthrough was that traditional display devices usually require electricity to write, but our technology made it closer to how we would use normal paper," John Chen, general director of the institute's Display Technology Center, told the wire agency Monday. "First, it does not ...

Using gold as a potential treatment for cancer could become a reality thanks to a combination of imaging techniques. In work published recently in The Royal Society of Chemistry journal Metallomics, researchers at The University of Western Australia and Griffith University's Institute for Glycomics describe how using two imaging techniques allows scientists to see where gold complexes used in potential chemotherapeutic treatments end up in cells. They are also able to monitor the gold's effects on the cells in a non-destructive way. Previous methods for this type of analysis were destructive to the cell. Lead author, Dr Louise Wedlock, who carried out the work while at UWA's ...

US Space weather scientists have predicted that large sun explosion over the last few days could affect communications and global positioning system (GPS) satellites. Weather scientists in the US have warned the users of satellite, telecommunications and electric equipment, due to three explosions from the sun, to be ready for possible disruptions during the next few days. "The magnetic storm that is soon to develop probably will be in the moderate to strong level," said Joseph Kunches, a space weather scientist at the Space Weather Prediction Center, a division of the U.S. National Oceanic and Atmospheric Administration (NOAA). Although solar activities rarely induce massive ...
Dieting forces brain to eat itself, scientists claim

Dieters struggle to lose weight because a lack of nutrition forces their brain cells to eat themselves, making the feeling of hunger even stronger, scientists claim. Like other parts of the body, brain cells begin to eat themselves as a last-ditch source of energy to ward off starvation, a study found. The body responds by producing fatty acids, which turn up the hunger signal in the brain and increase our impulse to eat. Researchers from the Albert Einstein College of Medicine at Yeshiva University in New York said the findings could lead to new scientifically proven weight loss treatments. Tests on mice found that stopping the brain cells from eating themselves – a process known ...

(Reuters) - Scientists have identified an emerging "superbug" strain of salmonella that is highly resistant to the antibiotic Ciprofloxacin, or Cipro, often used for severe salmonella infections, and say they fear it may spread around the world. The strain, known as S. Kentucky, has spread internationally with almost 500 cases found in France, Denmark, England and Wales in the period between 2002 and 2008, according a study in the Journal of Infectious Diseases. French researchers who led the study also looked at data from North America and said reports of infection in Canada and contamination of imported foods in the United States suggest the strain has also reached there. ...
