Alaska’s controversial HAARP facility closed -- will it come back online?
Post Date: 2013-07-23 21:16:00 by hondo68
Fringe thinkers have tenuously linked HAARP to everything from the 2011 Japanese Earthquake to mind control and hurricanes. But this almighty facility has been closed for weeks as the military hopes for a change between contractors to operate the facility.HAARP photo Alaskas High-Frequency Active Auroral Research Program (HAARP) has drawn its fair share of conspiracy theories over the years, as it sits in Gakona, an array of antennas intended to heat the Earths ionosphere and study the effects. Fringe thinkers have tenuously linked HAARP to everything from the 2011 Japanese Earthquake to mind control and hurricanes. But if there are no major earthquakes or bizarre global ...

Too green to be true? Researchers develop highly effective method for converting CO2 into methanol Jun 20, 2013
Post Date: 2013-06-23 18:38:07 by A K A Stone
Université Laval researchers have developed a highly effective method for converting CO2 into methanol, which can be used as a low-emissions fuel for vehicles. The team led by Professor Frédéric-Georges Fontaine presents the details of this discovery in the latest issue of the Journal of the American Chemical Society. Researchers have been looking for a way to convert carbon dioxide into methanol in a single step using energy-efficient processes for years. "In the presence of oxygen, methanol combustion produces CO2 and water," explained Professor Fontaine. "Chemists are looking for catalysts that would yield the opposite reaction. That would allow us to ...
Do you carry DNA of former lovers in your body?

This bit of science arcanum is especially cringe-worthy. Many years ago, scientists first discovered that a large minority of women have Y-chromosome gene sequences in their blood. At first glance, this seems strange. Men are born with Y-chromosomes but most women are not. The male cells in these women mustve come from somewhere else. But where? The most obvious source is a fetus. Nearly every woman who has ever been pregnant or had a baby has cells from her fetus circulating in her bloodstream. These cells filter through the placenta and reside in the mothers bloodstream and/or organs including her heart and brain for the rest of her life. This condition is ...

Scientists Invent Oxygen Particle That If Injected, Allows You To Live Without Breathing
Post Date: 2013-05-08 22:29:49 by A K A Stone
New Medical Discovery A team of scientists at the Boston Childrens Hospital have invented what is being considered one the greatest medical breakthroughs in recent years. They have designed a microparticle that can be injected into a persons bloodstream that can quickly oxygenate their blood. This will even work if the ability to breathe has been restricted, or even cut off entirely. This finding has the potential to save millions of lives every year. The microparticles can keep an object alive for up to 30 min after respiratory failure. This is accomplished through an injection into the patients veins. Once injected, the microparticles can oxygenate the blood to near ...
Climate scientists struggle to explain warming slowdown
Post Date: 2013-04-16 22:39:22 by jwpegler
Scientists are struggling to explain a slowdown in climate change that has exposed gaps in their understanding and defies a rise in global greenhouse gas emissions. Often focused on century-long trends, most climate models failed to predict that the temperature rise would slow, starting around 2000. Scientists are now intent on figuring out the causes and determining whether the respite will be brief or a more lasting phenomenon. Getting this right is essential for the short and long-term planning of governments and businesses ranging from energy to construction, from agriculture to insurance. Many scientists say they expect a revival of warming in coming years. Theories for the pause ...

Birds might be evolving to dodge vehicles
Post Date: 2013-03-18 12:50:54 by Ferret Mike
Fewer cliff swallows are being killed by moving vehicles. Does a new study offer a bird's-eye view into evolution? Fewer cliff swallows are being killed by moving vehicles because of evolution, suggests a study published online today in the journal Current Biology. "These birds have been exposed to vehicles and roads for 30-plus years," says Charles Brown, the study's lead author. "During that time, they have evolved to avoid being killed by traffic. Evolution can happen very rapidly, and some animals can adapt to urban environments very rapidly." The decrease in road deaths is likely because these birds have shorter wingspans, making them more agile fliers, ...
There Used To Be Freaking Camels In The Arctic
Post Date: 2013-03-06 20:00:18 by Ferret Mike
In the northernmost reaches of Canada, within the Arctic Circle, scientists have found fossils of...camels. Wait, what? North America was a crazy place a few million years ago. The megafauna alone would make the world's most awesome zoo collection: giant sloths! Mastodons! Nine-foot saber-toothed salmon! Dire wolves! And, believe it or not, camels. Yes, camels originally arose in North America 45 million years ago and lived there until human migrated into the area around 16,000 years ago. So, we might expect to find camels somewhere in North America, sure. But researchers just found fossils on Ellesmere Island, in the northern territory of Nunavut, Canada, far above the Arctic ...

Time to save up your plastic junk for recyling: mini shredder and FilaMaker
Post Date: 2013-02-01 16:07:49 by A K A Stone
In 2012, Marcus Thymark of Germany introduced his mini DIY shredder that can be used to recycle all your failed prints or any other plastic scrap. A year later, Marcus has improved his system and also started a new open source project: FilaMaker. FilaMaker is a personal filament producing machine that grinds old plastic and make new filament for your 3D printer. You can produce standard 1.75 mm or 3 mm filament by changing only one nozzle. The FilaMaker is still in development. Marcus is currently making some test with extruders. FilaMaker uses high pressure system which can work with low temperature to prevent degradation of plastic. The high pressure system can be used for plastic ...
Can We Trust CBS or CNET Again After a Scandal This Shady?
Post Date: 2013-01-14 21:20:14 by A K A Stone
CNET, one of the Internet's first and most influential authorities on gadgets and tech news, watched its editorial integrity spiral out of control Monday, with staffers quitting and editors left to explain themselves in the wake of explosive new charges over its annual Consumer Electronics Show awards — a scandal, it would appear, that goes all the way to the top of its corporate umbrella, and could shake the entire ecosystem of online tech journalism.

New thermoelectric material sucks electricity out of hot water
Post Date: 2013-01-01 17:36:36 by A K A Stone
When humans produce energy, we do it very inefficiently. Usually what happens is that we make something very hot (like a car engine), use a tiny bit of that energy to do work, and then spend even more energy getting rid of all the waste heat. Panasonic has developed a new thermoelectric material that can get a chunk of that energy back. A thermoelectric material is something that can convert heat directly into electricity. It's not a new thing, but generally it's so inefficient that anyone who's serious about capturing electricity through heat instead uses some sort of steam generator. Where thermoelectrics have potential is in microgenerators, where you're just looking ...
Unlocking New Talents in Nature: Protein Engineers Create New Biocatalysts
Post Date: 2012-12-30 16:45:09 by A K A Stone
Dec. 20, 2012 Protein engineers at the California Institute of Technology (Caltech) have tapped into a hidden talent of one of nature's most versatile catalysts. The enzyme cytochrome P450 is nature's premier oxidation catalyst -- a protein that typically promotes reactions that add oxygen atoms to other chemicals. Now the Caltech researchers have engineered new versions of the enzyme, unlocking its ability to drive a completely different and synthetically useful reaction that does not take place in nature. The new biocatalysts can be used to make natural products -- such as hormones, pheromones, and insecticides -- as well as pharmaceutical drugs, like antibiotics, in a ...
Helium Reserves, Cutting Spending, and Prudence
Post Date: 2012-12-28 13:08:50 by Abcdefg
In the comments of James' excellent post on the imprudence of arbitrarily cutting Federal workers, a discussion arose about "wasteful" Federal spending. In that discussion, James said: It never ceases to amaze me how hard it is to muster the political backbone to make obvious cuts. Aren't we still subsiding helium for dirigibles? This caught my attention because it's a subject near and dear to my heart: the absolutely, positively stupid, shortsighted, and ignorant manner in which Congress decided to privatize the Federal Helium Reserves. In the name, of course, of cutting costs. A little background is in order. It's true that yes, the Federal Helium Reserves were ...

Summation of Paper: Deliberately concealing information from parents for the sole purpose of getting them to comply with an official vaccination schedule could be considered as a form of ethical violation or misconduct. Official documents obtained from the UK Department of Health (DH) and the Joint Committee on Vaccination and Immunisation (JCVI) reveal that the British health authorities have been engaging in such practice for the last 30 years, apparently for the sole purpose of protecting the national vaccination program. The same vaccines that are MANDATED to American children. A Freedom of Information Act filed in the US with the CDC by a doctor with an ...

Study On Rising Sea Levels Likely Confirms Existence Of Global Warming
Post Date: 2012-12-02 12:45:48 by Brian S
A newly released study finds that ice sheets in Greenland and Antarctica are disappearing three times faster than they were two decades ago, the latest evidence supporting the existence of global warming. The study was published in the journal Science and is considered an extremely accurate portrayal of ice melts in these polar regions. According to the papers authors, the rapid polar ice melting has caused an increase in sea level that may become problematic to low coastal regions. Perhaps the most alarming data found by the researchers was in Greenland where the ice was melting an estimated five times the rate it was in the mid-1990s. Melt from Greenland accounted for a whopping ...
Will The Peak Of The Solar Cycle In 2013 Produce Technology Crippling Solar Super Storms?
Post Date: 2012-11-26 12:04:40 by hondo68
Our sun is becoming increasingly unstable, and most people have no idea the complete and utter devastation that a massive solar storm could potentially cause. A giant solar storm could potentially take out satellites, GPS systems, electrical grids, communication networks and pretty much anything else that runs on electricity or that relies upon electronics. And considering how dependent our society has become on technology, we are talking about an event that could possibly bring about the end of the world as we know it. Right now, solar activity is increasing as we approach the peak of Solar Cycle 24. But the worst is yet to come. Scientists are expecting a significant increase in coronal ...
Fetuses Yawn in the Womb, 4D Scans Suggest
Post Date: 2012-11-23 20:08:53 by A K A Stone
The 4D scans of 15 healthy fetuses, by Durham and Lancaster Universities, also suggest that yawning is a developmental process which could potentially give doctors another index of a fetus' health. The study is published Nov. 21 in the journal PLOS ONE. While some researchers have suggested that fetuses yawn, others have disagreed and claim it is simple mouth opening. But the new research clearly distinguished 'yawning' from 'non-yawn mouth opening' based on the duration of mouth opening. The researchers did this by using the 4D video footage to closely examine all events where a mouth stretch occurred in the fetus. Using their newly developed criteria, the ...
Human Intelligence Slowly Declining, Says Leading Geneticist
Post Date: 2012-11-13 10:42:21 by Brian S
Humans are slowly losing their cognitive capabilities as adverse genetic mutations fail to be weeded out by evolutionary pressures, according to a bold hypothesis put forward by Dr. Gerald Crabtree of Stanford University. I would wager that if an average citizen from Athens of 1000 BC were to appear suddenly among us, he or she would be among the brightest and most intellectually alive of our colleagues and companions, with a good memory, a broad range of ideas, and a clear-sighted view of important issues. Furthermore, I would guess that he or she would be among the most emotionally stable of our friends and colleagues, the leading geneticist began his article in the ...
Industry Radiation Experts Nail it: Greenhouse Gas Theory Debunked
Post Date: 2012-10-22 18:28:19 by Capitalist Eric
Typical Industrial Infrared Heater ( F J Evans Engineering Co) Millions of hours of commercial tests have scorched the cornerstone of global warming science: the disputed greenhouse gas effect. Hidden in plain sight for years has sat irrefutable evidence from heating manufacturers to prove that infrared radiation does not heat the air. Is this a big deal? You bet. It means that only in the fantasy world of climatologists computer models can man-made global warming still exist. Below Carl Brehmer is first to go public with this compelling new analysis.
