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 ...

Yahoo News: When you’re about to buy a new gadget or computer, you have to make a ton of decisions – decisions that could end up costing you way too much. So what are the worst tech rip-offs – and how can you avoid them? Rip-off #1: Buying from the Carrier Buying a new phone poses lots of questions – starting with: where should you get your new device? The cell service providers would love you to believe that if you buy from them, you’ll get an amazing package deal. They’d also love you to believe that you HAVE to get your phone from them. You don’t. As long as the type of phone is supported by the service provider you choose, you can often save a ...
Male baldness linked to risk of coronary heart disease, research claims

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 ...

Science Daily: Mar. 28, 2013 — Chemists at the California Institute of Technology (Caltech) and the Lawrence Berkeley National Laboratory believe they can now explain one of the remaining mysteries of photosynthesis, the chemical process by which plants convert sunlight into usable energy and generate the oxygen that we breathe. The finding suggests a new way of approaching the design of catalysts that drive the water-splitting reactions of artificial photosynthesis. "If we want to make systems that can do artificial photosynthesis, it's important that we understand how the system found in nature functions," says Theodor Agapie, an assistant professor of chemistry at ...

Researchers believe they have pinpointed the skeletal remains of the first known human-Neanderthal hybrid, according to a study published Wednesday in the peer reviewed scientific journal PLoS ONE. The finding comes from northern Italy, where some 40,000 years ago scientists believe Neanderthals and humans lived near each other, but developed separate and distinctly different cultures. A portion of a jawbone found during an archaeological dig in the area reveals that the bone’s owner had facial features attributable to both modern humans and Neanderthals, the study explains. Scientists have debated the theory of human-Neanderthal interbreeding since DNA analysis revealed in 2010 ...

Ephemeral vacuum particles induce speed-of-light fluctuations March 25, 2013 New research shows that the speed of light may not be fixed after all, but rather fluctuates. Two forthcoming European Physical Journal D papers challenge established wisdom about the nature of vacuum. In one paper, Marcel Urban from the University of Paris-Sud, located in Orsay, France and his colleagues identified a quantum level mechanism for interpreting vacuum as being filled with pairs of virtual particles with fluctuating energy values. As a result, the inherent characteristics of vacuum, like the speed of light, may not be a constant after all, but fluctuate. Meanwhile, in another study, Gerd Leuchs and ...

For many of us, the concept of living in a place with stuff growing on its walls won’t necessarily be foreign. What will be unusual for those who have experienced the joys of residing in damp student flats and first homes away from the parental nest, however, is the idea that microorganisms flourishing on your walls is a good thing. This is precisely the logic at work in the construction of a state-of-the-art apartment building in the once rundown, but increasingly trendy riverside quarter of Wilhelmsburg in Hamburg. Clad on its two south-facing sides with a transparent shell housing millions of microalgae, the five-storey Bio Intelligence Quotient (BIQ) house has been designed to ...

Wal-Mart shoppers will be able bypass the traditional checkout process at more than 200 stores with the Scan & Go app, but they still must pay the old-fashioned way. Wal-Mart Stores Inc. said it is tripling the number of U.S. stores in a pilot program that lets shoppers scan items with their iPhones and pay at self-checkout counters. Wal-Mart's Scan & Go program will soon be in more than 200 stores, up from about 70. The pilot began near its home office in Bentonville, Ark., in late 2012, then expanded to Atlanta. While the program is tripling in size, for now it will be in only a small fraction of Wal-Mart's more than 4,000 U.S. stores. Walmart expanding iPhone-based ...
