ScienceDaily... Aug. 22, 2013 — In the aftermath of a heart attack, cells within the region most affected shut down. They stop beating. And they become entombed in scar tissue. But now, scientists at the Gladstone Institutes have demonstrated that this damage need not be permanent -- by finding a way to transform the class of cells that form human scar tissue into those that closely resemble beating heart cells. Share This: ? Last year, these scientists transformed scar-forming heart cells, part of a class of cells known as fibroblasts, into beating heart-muscle cells in live mice. And in the latest issue of Stem Cell Reports, researchers in the laboratory of Gladstone Cardiovascular ...

Al Gore and his traveling medicine show is back in town with his new, improved snake oil, guaranteed to grow hair, improve digestion, promote regularity and kill roaches, rats and bedbugs. Al and his wagon rumbled into town on the eve of “a major forthcoming report” from the Intergovernmental Panel on Climate Change, which is a panel of scientists affiliated with the United Nations. Their report is expected to buck up the spirits of the tycoons of the snake-oil industry. A snake-oil salesman’s lot, like a policeman’s, is not a happy one. There’s always a skeptic or two (or three) standing at the back of the wagon, eager to scoff and jeer. The global-warming scam ...

Aug. 20, 2013 — The Lighting Research Center (LRC) at Rensselaer Polytechnic Institute recently released a guide for designing light scoops -- an innovative type of skylight designed by the LRC with funding from the New York State Energy Research and Development Authority (NYSERDA). Light scoops provide optimal levels of daylight throughout the changing seasons and daily fluctuations in weather by capturing and strategically redirecting daylight into buildings. Share This: ? Many conventional horizontal skylights provide too much sun on days that are warm and sunny, and too little sun on days that are cold and dark. The LRC's new light scoops design balances out these daily and ...

Earth was attacked by a solar super storm on Tuesday, August 20, sending giant clouds of extremely heated particles directly towards us. The storm, known as coronal mass ejection (CME) took place at 4:24 a.m. EDT (0824 GMT) on Tuesday and unleashed billions of tons of solar particles toward Earth at an unimaginable speed of two million miles per hour (mph). “Experimental NASA research models based on observations from NASA’s Solar Terrestrial Relations Observatory, show that the CME left the sun at speeds of around 570 miles per second, which is a fairly typical speed for CMEs,” NASA officials wrote in an update on Tuesday. NASA’s twin Stereo spacecraft and the Solar ...

Earlier tonight JT posted an article from The Onion. When I clicked the link to go to the source I got it for just a couple of seconds and then it disappeared. Happened again when I just typed in theonion.com without the rest of the url that went to that specific article. It came up but just for a second or two and then vanished. I have no idea why that happened or how it is possible. That is why I am asking--thanks for clearing it up for me if you understand it (I sure don't).
Taco Bell serving ‘soylent gringo’? GMO corn causes concern

(PNS reporting from WASHINGTON, DC) A new Food and Drug Administration study has detected a questionable strain of genetically-engineered corn in taco shells produced for Taco Bell. “It could cause digestive problems, cramping, spasms, allergic reactions and even night blindness,” Colonel Ben Enoso of the FDA’s Genetic Corn Division told a press conference Monday. “Unfortunately, this makes it pretty hard to distinguish from other Taco Bell food items.” The corn, which carries a gene designed to kill insect pests if eaten, has been approved as feed for animals but not humans. Scientists suspect the human body will not be able to digest a key protein in this killer ...

What's the MEMS stock being teased by Michael Robinson's Radical Technology Profits? Radical Technology Profits, edited by Michael Robinson over at Money Map Press, is one of the newsletters that, like Breakthrough Technology Alert or the many other competitors, aims to get in early on technology and biotech stories — and also like most of these letters, they pitch their ideas by selling a big picture story that weaves some little company’s product into a larger and more easily identified trend that sounds entirely plausible. Which isn’t to say that they’re all bad ideas — far from it, I’m sure these kinds of “breakout technology” ...
Light-heat selectivity in windows

— Researchers at the U.S. Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) have designed a new material to make smart windows even smarter. The material is a thin coating of nanocrystals embedded in glass that can dynamically modify sunlight as it passes through a window. Unlike existing technologies, the coating provides selective control over visible light and heat-producing near-infrared (NIR) light, so windows can maximize both energy savings and occupant comfort in a wide range of climates. "In the US, we spend about a quarter of our total energy on lighting, heating and cooling our buildings," says Delia Milliron, a chemist at Berkeley ...

Imagine driving on the freeway at 60 miles per hour and your car suddenly screeches to a halt, causing a pileup that injures dozens of people. Now imagine you had absolutely nothing to do with the accident because your car was taken over by hackers. Charlie Miller, a security researcher at Twitter, and Chris Valasek, director of security intelligence at IOActive, a security research company, recently demonstrated car hacks at the DefCon computer security conferences in Las Vegas. The researchers completely disabled a driver’s ability to control a vehicle. No brakes. Distorted steering. All with a click of a button. While the demos were with hybrid cars, researchers warn that dozens of ...

Everything old is new again. Partially borrowing a technology concept used by banks, entrepreneur Elon Musk introduced a design for a new transportation system that he said could shuttle passengers between Los Angeles and San Francisco in 30 minutes. For now, it's an early, conceptual design at best -- a proposal for an idea that may never be built and likely gone unnoticed had it not been for the attention Musk receives for his other projects, including Tesla Motors and PayPal. "The Hyperloop (or something similar) is, in my opinion, the right solution for the specific case of high traffic city pairs that are less than about 1500 km or 900 miles apart," he wrote on his ...

Fighting Scientism Without Theism

I feel like we go around this track every other month. A scientist or science- popularizer writes an unpersuasive essay arguing that science “proves” that religion is bad for children and other living things; a theist responds with an unpersuasive essay arguing that without some grounding in the divine, we’re doomed to become Nazis. Here’s the latest go-round with Ross Douthat critiquing Steven Pinker. It’s almost as if nobody in the debate wants to acknowledge that there are whole libraries of philosophical debate about these “how shall we live” questions that don’t start either with Thomas Aquinas or Jeremy Bentham. Heck, there are entire ...

Every August, just when many people go vacationing in the country where skies are dark, the best- known meteor shower, makes its appearance. This year, the Perseid meteor shower is expected to reach its peak overnight on Monday (Aug. 12), and there are some key tips to keep in mind for your "shooting stars" viewing. Peak activity for the Perseids is unfortunately predicted for the daylight hours across North America, so stargazers with clear skies are encouraged to seek out the meteor display during the pre-dawn hours of Monday and again during the early morning hours of Tuesday (Aug. 13). At these times, the absence of bright moonlight can maximize your chances of spotting a ...

Genetic ancestors ‘Adam’ and ‘Eve’ could have been contemporaries, scientists say

Most evolutionary anthropologists say that the event depicted in Albrecht Dürer's 1507 painting, 'Adam and Eve,' is apocryphal, but new evidence suggests that humanity's most recent common male and female ancestor might have lived at the same time. Thousands of years ago, somewhere in Africa, lived a man who – probably – had no idea that he, among all the other men in his group, would go on to become humankind’s most recent common male ancestor. Scientists would call him “Adam.” Now, a new paper published in the journal Science significantly narrows the time during which Adam could have lived – about 120,000 to 156,000 years ago – ...
