The Bone Destroying Daily Drink Fooling Millions of Americans
Post Date: 2011-08-08 09:21:25 by A K A Stone
Two new North American studies investigated the impact of low-level fluoride consumption on the strength and density of bone. While these important (yet largely overlooked) studies are not slam-dunks, they provide some of the strongest evidence to date that low-level fluoride exposure alters the quality of bone tissue, and strengthen concerns that fluoride exposure may increase the rate of bone fracture in the population. Skeletal FluorosisA Real Danger of Excessive Fluoride Consumption The harmful effects of chronic fluoride exposure on bone are well established. Since the 1930s it has been known that fluoride intake causes excessive bone growth, which can result in joint pain, ...
Happy 20th birthday, World Wide Web!
Post Date: 2011-08-06 19:36:10 by jwpegler
Happy birthday, Web! On August 6, 1991--20 years ago--Tim Berners-Lee posted a summary of a project for organizing information on a computer network using a "web" of hyperlinks: the "WorldWideWeb," or W3. At the same time, the W3 made its debut as a publicly available service on the Internet. Now, as the Web turns 20, those of us here at CNET and sister site CBS News.com are giving it a big thank you for revolutionizing the world as we know it. There have been some definite downsides to the Web, such as online predation and a reduction in privacy, but the good has far outweighed the bad. Web companies have created millions of jobs across the globe, opened people up to ...

No, new data does not “blow a gaping hole in global warming alarmism”
Post Date: 2011-07-29 15:44:53 by go65
I received a few emails, tweets, and comments on the blog yesterday asking about an Op/Ed article in Forbes magazine that claims that new NASA data will "blow [a] gaping hole in global warming alarmism". Except, as it turns out, not so much. The article is just so much hot air (see what I did there?) and climate scientists say the paper on which its based is fundamentally flawed and flat-out wrong. Its clear after reading just a few words that this article is hugely biased. The use of the word "alarmist" and its variants appeared no fewer than 14 times, 16 if you include the picture caption and the headline. The word "alarmist" is pretty clearly ...
New NASA Data Blow Gaping Hole In Global Warming Alarmism
Post Date: 2011-07-28 18:25:37 by Sebastian
NASA satellite data from the years 2000 through 2011 show the Earth's atmosphere is allowing far more heat to be released into space than alarmist computer models have predicted, reports a new study in the peer-reviewed science journal Remote Sensing. The study indicates far less future global warming will occur than United Nations computer models have predicted, and supports prior studies indicating increases in atmospheric carbon dioxide trap far less heat than alarmists have claimed. Study co-author Dr. Roy Spencer, a principal research scientist at the University of Alabama in Huntsville and U.S. Science Team Leader for the Advanced Microwave Scanning Radiometer flying on ...

Fingerprint Analysis Tech Aims To Revolutionize Drug Testing
Post Date: 2011-07-26 11:51:38 by Brian S
A new technology that analyzes the sweat from a person's fingertips looks to revolutionize the drug testing market, providing on-site results in minutes with a test so advanced it can even detect marijuana intoxication. Using gold nanoparticles and special antibodies, the tech produced by British firm Intelligent Fingerprinting latches on to metabolites on the fingerprint and turns a specific color depending on which drug byproducts are detected. While it can be configured to search for drugs like nicotine, methadone and cocaine, it also presents another innovation: helping to determine if someone is actively intoxicated on marijuana. Marijuana's psychoactive ingredient is fat ...
We are destined to travel to other worlds
Post Date: 2011-07-19 23:59:46 by Annica Mc
I think that there are many species in universe. We are destined to either destroy ourselves or travel to other planets and dimensions. I think it is imperative that our govt develop our technology so that those of us that want to leave this world can go and seek better opportunities and more happiness. There is way to much fiction in this world for us in the know to be able to coexist with these people on this planet and their ancient superstitions. We need to encourage Obama to turn Nasa's attention to the development of a warp drive. It would be well worth the effort. When the warp drive is developed we will leave this world and no zionists will be allowed to come.

Scientists Unveil New Tools for Rewriting the Code of Life
Post Date: 2011-07-15 15:15:46 by jwpegler
The power to edit genes is as revolutionary, immediately useful and unlimited in its potential as was Johannes Gutenberg's printing press. And like Gutenberg's invention, most DNA editing tools are slow, expensive, and hard to use -- a brilliant technology in its infancy. Now, Harvard researchers developing genome- scale editing tools as fast and easy as word processing have rewritten the genome of living cells using the genetic equivalent of search and replace -- and combined those rewrites in novel cell strains, strikingly different from their forebears. "The payoff doesn't really come from making a copy of something that already exists," said George Church, a ...
China’s ‘Eye-In-The-Sky’ Nears Par With US
Post Date: 2011-07-12 14:54:21 by Brian S
Chinas rapidly expanding satellite programme could alter power dynamics in Asia and reduce the US militarys scope for operations in the region, according to new research. Chinese reconnaissance satellites can now monitor targets for up to six hours a day, the World Security Institute, a Washington think-tank, has concluded in a new report. The Peoples Liberation Army, which could only manage three hours of daily coverage just 18 months ago, is now nearly on a par with the US military in its ability to monitor fixed targets, according to the findings. Starting from almost no live surveillance capability 10 years ago, today the PLA has likely equalled the USs ...
New laser technology could kill viruses and improve DVDs
Post Date: 2011-07-11 21:59:42 by A K A Stone
A team led by a professor at the University of California, Riverside Bourns College of Engineering has made a discovery in semiconductor nanowire laser technology that could potentially do everything from kill viruses to increase storage capacity of DVDs. Ultraviolet semiconductor diode lasers are widely used in data processing, information storage and biology. Their applications have been limited, however, by size, cost and power. The current generation of ultraviolet lasers is based on a material called gallium nitride, but Jianlin Liu, a professor of electrical engineering, and his colleagues have made a breakthrough in zinc oxide nanowire waveguide lasers, which can offer smaller ...
The Green Nazi Deep Ecology of Martin Heidegger
Post Date: 2011-07-10 08:20:39 by CZ82
The Green Nazi Deep Ecology of Martin Heidegger By Mark Musser One of the most influential philosophers of the 20th century, foundational to the academic left and deep ecology of the greens, was committed to Nazism. The green Nazi/deep ecology connection in the life and works of Martin Heidegger have been routinely given a pass over the years by many western scholars who love his existential philosophy. According to French professor Emmanuel Faye's latest book on Heidegger, the days of viewing his commitment to Nazism as something incidental to his life are now officially over. In his book Heidegger: The Introduction of Nazism into Philosophy in Light of the Unpublished Seminars ...
After Last Shuttle Lifts Off, Russia Owns Space
Post Date: 2011-07-08 20:48:16 by Brian S
(Newser) After the last US space shuttle flight blasts off tomorrow, Russia will officially have a monopoly on outer space. The 40-year-old Soyuz capsule will be the only vessel capable of reaching the International Space Station, and Russia can charge dearly for rides, the Wall Street Journal reports. We are not in a very comfortable situation, and when I say uncomfortable, that is a euphemism, says the director of the European Space Agency. We made a collective mistake. Already, Russia has increased its asking price 175% since George W. Bush announced the end of the shuttle program in 2004and itll rise again later this summer, to $43.4 million ...

Credit: Reuters/Kim Kyung-Hoon LONDON (Reuters) - Smoke belching from Asia's rapidly growing economies is largely responsible for a halt in global warming in the decade after 1998 because of sulphur's cooling effect, even though greenhouse gas emissions soared, a U.S. study said on Monday. The paper raised the prospect of more rapid, pent-up climate change when emerging economies eventually crack down on pollution.World temperatures did not rise from 1998 to 2008, while manmade emissions of carbon dioxide from burning fossil fuel grew by nearly a third, various data show.

Russia Gains Edge In Space Race As US Shuttle Bows Out
Post Date: 2011-07-04 11:32:46 by Brian S
MOSCOW As the United States winds down its shuttle programme in a symbolic twist in a long-running space rivalry, Russia will gain complete control of access to the International Space Station. The Russian space agency plays down any triumphalism, but US astronauts will remain dependent on Russia for access to the ISS at least until 2015 and will have to pay for seats in its Soyuz space capsules. "We cannot say that we have won the space race, but simply that we have reached the end of a certain stage," the deputy head of the Russian space agency, Vitaly Davydov, said in an interview. On July 8, four US astronauts will board the Atlantis shuttle for its last flight, ...

Chemical in plastic containers makes male mice act like females By Agence France-Presse Monday, June 27th, 2011 -- 6:51 pm WASHINGTON Male mice who were exposed as babies to BPA, a chemical common in canned foods and plastic containers, act more like females and are seen as less desirable mates, a US study showed Monday. The findings could have implications for how BPA, or Bisphenol A, may affect human development and behavior, said the study published in the Proceedings of the National Academy of Sciences. "The BPA-exposed deer mice in our study look normal; there is nothing obviously wrong with them. Yet, they are clearly different," said lead author Cheryl ...
Why guzzling diet drinks could make you FATTER - they can trigger the appetite
Post Date: 2011-06-28 14:13:15 by Capitalist Eric
Diet soft drinks can actually make people fatter, say scientists. Reaching for the Diet cola is a bad idea for those trying to cut calories - because it may make you want to eat more, according to two studies. Artificial sweeteners could be to blame, as they were shown to increase blood sugar levels over time, and researchers believe they could also actually trigger the appetite. In one study that followed nearly 500 people, those who drank any amount of the soft drinks each day had 70 per cent bigger waists after a decade than those who drank none. And those who drank two or more a day had roughly a five-fold increase - almost two inches around the girth, according to the findings ...
Inflatable Shark Among 300 New Species Discovered in Philippines
Post Date: 2011-06-28 00:13:52 by A K A Stone
treasure trove of hundreds of new species may have been discovered in the Philippines, including a bizarre sea star that feeds exclusively on sunken driftwood and a deep-sea, shrimp-eating shark that swells up to scare off other predators. Scientists braved leeches and a host of venomous creatures from the mountains to the sea to uncover more than 300 species that are likely new to science. These findings include dozens of new insects and spiders, more than 50 colorful new sea slugs and a number of deep-sea armored corals "which protect themselves against predatory nibbles from fish by growing large, spiky plates," said researcher Terrence Gosliner, dean of science and research ...
Conservatives Scare More Easily Than Liberals, Say Scientists
Post Date: 2011-06-24 11:15:40 by lucysmom
Deep-seated political differences arent simply moral and intellectual: Theyre also biological. In reflex tests of 46 political partisans, psychologists found that conservatives were more likely than liberals to be shocked by sudden threats. Accompanying the physiological differences were deep differences on hot-button political issues: military expansion, the Iraq war, gun control, capital punishment, the Patriot act, warrantless searches, foreign aid, abortion rights, gay marriage, premarital sex and pornography. "People are experiencing the world, experiencing threat, differently," said University of Nebraska political scientist John Hibbing. "We have very ...

New battery design could give electric vehicles a jolt
Post Date: 2011-06-07 22:19:49 by Skip Intro
Significant advance in battery architecture could be breakthrough for electric vehicles and grid storage. A radically new approach to the design of batteries, developed by researchers at MIT, could provide a lightweight and inexpensive alternative to existing batteries for electric vehicles and the power grid. The technology could even make refueling such batteries as quick and easy as pumping gas into a conventional car. The new battery relies on an innovative architecture called a semi-solid flow cell, in which solid particles are suspended in a carrier liquid and pumped through the system. In this design, the batterys active components the positive and ...
‘Malintent Detection’ Technology Tested In The Northeast United States
Post Date: 2011-05-31 15:53:16 by Brian S
The U.S. Department of Homeland Security (DHS) has begun field testing new technology designed to identify people who intend to commit a terrorist act. Nature reported that the DHS has been conducting tests of Future Attribute Screening Technology (FAST) in the past few months at an undisclosed location in the northeast. The technology uses remote sensors to measure physiological properties, such as heart rate and eye movement, which can be used to infer a person's current mindset. According to a Privacy Impact Assessment (PDF) released by the DHS in 2008, the technology is intended to measure a person's malintent -- the intent to cause harm. "Behavioral scientists ...

A new golden age of Egyptology may have only just begun. But this time things are a little different. Instead of treks through the desert, khaki hats, and camel rides into the sunset, modern archeologists are using satellite imaging and modern technology to uncover the lost secrets of Egypt. Astoundingly, scientists at the University of Alabama at Birmingham believe they have discovered 17 "lost" pyramids using this methodology, according to MSNBC. 1,000 tombs and 3,000 ancient settlements have also been uncovered with the use of infra-red technology, according to the BBC. Thus far, at least two of the suspected pyramids have been confirmed and excavated. From the BBC: We ...
