NEW YORK (Reuters) - After more than 15 years of failures by scientists around the world and one outright fraud, biologists have finally created human stem cells by the same technique that produced Dolly the cloned sheep in 1996: They transplanted genetic material from an adult cell into an egg whose own DNA had been removed. The result is a harvest of human embryonic stem cells, the seemingly magic cells capable of morphing into any of the 200-plus kinds that make up a person. The feat, reported on Wednesday in the journal Cell, could re-ignite the field of stem-cell medicine, which has been hobbled by technical challenges as well as ethical issues. Until now, the most natural sources ...
Warp Drive Feasible? Relativity Loophole Means 'Star Trek' Device Might Actually Work, Physicists Say
Post Date: 2013-05-15 07:41:56 by Ada

In the "Star Trek" TV shows and films, the U.S.S. Enterprise's warp engine allows the ship to move faster than light, an ability that is, as Spock would say, "highly illogical." However, there's a loophole in Einstein's general theory of relativity that could allow a ship to traverse vast distances in less time than it would take light. The trick? It's not the starship that's moving — it's the space around it. In fact, scientists at NASA are right now working on the first practical field test toward proving the possibility of warp drives and faster-than-light travel. Maybe the warp drive on "Star Trek" is possible after all. [See ...

In the near future our mobile phones will be powered by wearable electronics that incorporate piezoelectric devices into fabric. Image: Image: Yonggang Huang/Northwestern University Imagine having a wafer-thin touchscreen on your sleeve that, like a scene out of a Philip K. Dick novel, gives you all the functionality of a smartphone without the awkwardness of a cumbersome battery. The best part about this scenario is it may not be as far from reality as you think. The bulky packaging of batteries limits innovation of some of the amazing new, ultra-slim electronics today. If you open up an iPhone 5, you’ll see that a large proportion of the phone’s volume is taken up by the ...
Wheat-tomato rotation helps reduce nematodes: study
Post Date: 2013-05-14 23:38:58 by Tatarewicz
0 Comments
WASHINGTON, May 14 (Xinhua) -- U.S. researchers said Tuesday they have found a resistant strain of wheat that can reduce nematode numbers in soil and protect the next rotation of tomato plants. Root-knot nematodes cause crop losses around the world, and they can be difficult to control. Once they are present in soil, they can survive winter in a fallow field and infect plants during the next growing season. The resistant wheat, however, serves as a trap crop to trick the nematodes into starting their life cycle but then prevents them from reproducing, according to researchers at the University of California, Davis, who described it in the journal Crop Science as "a better option ...

May 13, 2013 — Most Americans want the U.S. to place more emphasis on developing solar power, recent polls suggest. A major impediment, however, is the cost to manufacture, install and maintain solar panels. Simply put, most people and businesses cannot afford to place them on their rooftops. Share This: Tweet Fortunately, that is changing because researchers such as Qiaoqiang Gan, University at Buffalo assistant professor of electrical engineering, are helping develop a new generation of photovoltaic cells that produce more power and cost less to manufacture than what's available today. One of the more promising efforts, which Gan is working on, involves the use of ...

THE act of exploring helps shape the brain and adventuring is what makes each individual different, according to researchers in Germany. The findings published in the US journal Science may offer new paths to treating psychiatric diseases, scientists said. Researchers sought to pin down why identical twins are not perfect replicas of each other, even when they have been raised in the same environment, and studied the matter using 40 genetically identical mice. The mice were kept in an elaborate, five-level cage connected by glass chutes and filled with toys, scaffolds, wooden flower pots, nesting places and more. The space available to explore spanned about five square metres (yards). ...
Is science being corrupted to the point of fraud?

Petroleum and coal are referred to as fossil fuels, which supposedly means they started out as biological materials. They didn't. Oil and coal are in a higher state of chemical energy than biological materials. They are often called hydrocarbons, because they have hydrogen attached to carbon, which is a high energy state. Biological materials have a lot of oxygen added, which is a lower energy state. There is no method of increasing chemical energy other than through radiation. Commentators blissfully mention heat and pressure. Those forces cannot increase chemical energy, because they act upon nuclei, while chemical energy is in electrons which spin around nuclei. No force acting upon ...

Science Daily: May 8, 2013 — Anyone who has seen pictures of the giant, red-hot cauldrons in which steel is made -- fed by vast amounts of carbon, and belching flame and smoke -- would not be surprised to learn that steelmaking is one of the world's leading industrial sources of greenhouse gases. But remarkably, a new process developed by MIT researchers could change all that. Share This: The new process even carries a couple of nice side benefits: The resulting steel should be of higher purity, and eventually, once the process is scaled up, cheaper. Donald Sadoway, the John F. Elliott Professor of Materials Chemistry at MIT and senior author of a new paper describing the process, ...

Explainer: what is intuition?
Post Date: 2013-05-06 04:27:58 by Tatarewicz
0 Comments
Science Alert: The word intuition is derived from the Latin intueor – to see; intuition is thus often invoked to explain how the mind can “see” answers to problems or decisions in the absence of explicit reasoning – a “gut reaction”. Several recent popular psychology books – such as Malcolm Gladwell’s Blink, Daniel Kahneman’s Thinking Fast and Slow and Jonah Lehrer’s The Decisive Moment – have emphasised this “power of intuition” and our ability to “think without thinking”, sometimes suggesting we should rely more heavily on intuition than deliberative (slow) or “rational” thought processes. Such books ...

This week the rocket motor on the Scaled Composite built SpaceShipTwo was fired in flight for the first time. The Burt Rutan designed rocketplane accelerated beyond Mach 1and reached an altitude of about 55,000 feet during the short rocket burn. It was an important step in testing what will probably be the first civilian craft to carry passengers into space. The initial suborbital flight is expected to happen next year. Price of a passenger ticket is said to be $200,000. This second space race, one being conducted this time by private industry instead of cold war enemy governments, raises the question of just what is space? Where does space begin? How does one know when they reach space? ...

With a bomb strapped to his chest, one of the Boston Marathon suspects was killed early Friday after he and his accomplice robbed a 7-Eleven, shot a police officer to death, carjacked an SUV and hurled explosives out the window in an extraordinary firefight with law enforcement, authorities told NBC News. The second suspect — the one in the white hat in photos released by the FBI — was on the loose, and police ordered people in the Boston suburb of Watertown to stay in their homes and businesses not to open. Boston shut down its buses and subway system for the hunt. The suspects are brothers with the last name Tsarnaev, law enforcement officials told NBC News. The suspect at ...

Power Practical, a student startup that sprang from research at the University of Utah, is selling a portable cook pot that transforms heat and water into a power source. Imagine charging your cellphone or using speakers in the mountains at night far from civilization. That's what the device, called the PowerPot, can do with just a campfire and a little water. Using thermoelectricity, the PowerPot generates power by capturing the electrons moving from the heated pot to the cooler water inside. The greater the temperature difference, the more electricity is generated. The company has a growing variety of PowerPots that serve different needs. The basic model, the PowerPot V, weighs ...
Two Intifadas and a Flawed Theory

For at least a decade, Colonel Tom Hammes has been one of the Marine Corps’ leading intellectuals. His book The Sling and the Stone: On War in the 21st Century should be read by anyone who has an interest in Fourth Generation warfare (4GW). In some ways, this is two books in one. One book describes Fourth Generation war and the reforms our military needs in order to fight it, and here Colonel Hammes is at his best. His distinction between the first and second intifadas is especially valuable. He writes that the Palestinians won the first intifada because they were careful to present themselves as victims of a vastly more powerful Israeli military. Avoiding the use of weapons other ...
FreeStyle InsuLinx Glucose Meter Voluntarily Recalled in United States

Abbott is voluntarily recalling its FreeStyle InsuLinx blood glucose meters in the United States due to a malfunction that could lead to a delay in the identification and treatment of severe hyperglycemia or incorrect treatment being given, which could potentially lead to serious injury or death. The problem is occurring at extremely high blood glucose levels of 1024 mg/dL and above, says the company. When this happens, the FreeStyle InsuLinx Meter will display and store in memory an incorrect test result that is 1024 mg/dL below the measured result. For example, at a blood glucose value of 1066 mg/dL, the meter will display and store a value of 42 mg/dL (1066 mg/dL - 1024 mg/dL = 42 ...

Bald men are at greater risk of developing heart problems than those who retain a full head of hair – but only those with hair loss on top of their heads, and not at the front, are affected, new research suggests. While baldness is associated with an increased risk of coronary heart disease (CHD), men who have a receding hairline are not at heightened risk of the condition, according to a study in the journal BMJ Open. Researchers in Japan who examined six previous studies from Europe and America of the link between baldness and CHD, comprising 36,990 men, found that five of the studies confirmed an association. Men who have lost most of their hair are 32% more likely to go on to ...

Science Daily Apr. 4, 2013 — The number of online educational offerings has exploded in recent years, but their rapid rise has spawned a critical question: Can such "virtual" classes cut through the maze of distractions -- such as email, the Internet, and television -- that face students sitting at their computers? The solution, Harvard researchers say, is to test students early and often. By interspersing online lectures with short tests, student mind-wandering decreased by half, note-taking tripled, and overall retention of the material improved, according to Daniel Schacter, the William R. Kenan Jr. Professor of Psychology, and Karl Szpunar, a postdoctoral fellow in ...
