Science gets short shrift in California elementary schools, study finds By Diana Lambert dlambert@sacbee.com Published: Saturday, Nov. 5, 2011 - 11:00 pm | Page 1B Few local educators are surprised by a recent UC Berkeley study that says most California children aren't getting a decent science education. Gretchen Bly, a first-grade teacher at Rancho Cordova Elementary School, generally teaches about 90 minutes of science a week, integrating it into the curriculum as much as possible. "If I had my druthers, we'd do it three or four hours a week," said Bly, who coordinates the school's annual Science Night and other science programs. "With 32 students and less ...

Biggest jump ever seen in global warming gases By SETH BORENSTEIN, AP Thu Nov 3, 7:05 PM EDT WASHINGTON — The global output of heat-trapping carbon dioxide jumped by the biggest amount on record, the U.S. Department of Energy calculated, a sign of how feeble the world's efforts are at slowing man-made global warming. The new figures for 2010 mean that levels of greenhouse gases are higher than the worst case scenario outlined by climate experts just four years ago. "The more we talk about the need to control emissions, the more they are growing," said John Reilly, co-director of MIT's Joint Program on the Science and Policy of Global Change. The world pumped ...

How Albert-László Barabási went from mapping systems to controlling them In 1736 the Swiss mathematician Leonhard Euler ended a debate among the citizens of Königsberg, Prussia, by drawing a graph. The Pregel River divided the city, now Kaliningrad, Russia, into four sections. Seven bridges connected them. Could a person cross all seven without walking over the same one twice? Euler began with a map that cleared away everything—the homes and streets and coffeehouses—irrelevant to the question at hand. Then he translated that map into something even more abstract, a depiction not of a physical place but of an interconnected system. The four sections ...

Never mind the recent spate of satellite showers. An asteroid the size of an aircraft carrier is sailing toward Earth, NASA says. Never fear, however. The space agency says that although next week's flyby of Asteroid 2005 YU55 will bring the rock closer to our home planet than even the moon gets, the asteroid will cruise safely past, leaving in its wake not destruction but data. The agency has already begun using radio waves to scan the 1,300-foot-wide space rock, which will get closest to Earth on Tuesday at about 3:30 p.m. PT. With antennas at its Deep Space Network at Goldstone, Calif., and the Arecibo Planetary Radar Facility in Puerto Rico, NASA hopes to gather a wealth of detail ...
Removing Old Cells Could Extend Human Life

Removal of specific cells that accumulate with age can delay or prevent the onset of age-related disorders, new research suggests. If adapted for humans, this intervention may represent an avenue for treating or delaying age-related diseases and improving healthy lifespan in humans. The old adage "Out with the old and in with the new" could help prevent age-related diseases if applied to certain cells, new research on mice suggests. By removing the body's worn-out cells, called senescent cells, several times during the lifetime of aging-accelerated mice, researchers were able to spare the mice of cataracts, aging skin and muscle loss. "We started treating animals ...

9,000 year old Caucasian mummy found in Nevada [Full Thread]

"> Poster Comment:I suspect that the real reason that the Paiute's do not want the mummy DNA tested is because if it is Caucasoid, as is "Kennewick Man" it provides another data point showing that the Indians were NOT the first inhabitants of the North American Continent. So, the real reason is ethnic politics. Of course there will be narrow parochial assertions made by the "White is Right" crowd as though this proves anything beyond the established evidence suggesting that North America has been inhabited much longer than the Lamestream Archaeologists wish to put forth and by more than one group having disparate geographical origins. Both groups are likely ...

The so-called fine-structure constant, denoted by the symbol ‘alpha' - seems to vary across the Universe. One of the laws of nature may vary across the Universe, according to a study published today in the journal Physical Review Letters. One of the most cherished principles in science - the constancy of physics - may not be true, according to research carried out at the University of New South Wales (UNSW), Swinburne University of Technology and the University of Cambridge. The study found that one of the four known fundamental forces, electromagnetism - measured by the so-called fine-structure constant and denoted by the symbol ‘alpha' - seems to vary across the ...

New research on brain cells could shed more light on neurological diseases, scientists have discovered. Researchers from The Roslin Institute at the University of Edinburgh have found brain cells alter their genetic make-up during a person's lifetime. They have identified genes - known as retrotransposons - responsible for thousands of tiny changes in the DNA of brain tissue. Researchers, whose work is published in the journal Nature, found that the genes were particularly active in areas of the brain linked to cell renewal. By mapping the locations of these genes in the human genome, scientists could identify mutations that impact on brain function and that may cause diseases to ...

With its unique properties, the applications for the metal appeared so vast and revolutionary that, at the time, they bordered science fiction: Half the weight of titanium and twice as stiff Transparent to X-rays Doesn't spark Non-magnetic Doesn't rust Extremely low neutron absorption rate Owning the atomic number 4, it's the lightest metal on the planet next to its unpredictable neighbor, lithium. These scientists knew combining it as an alloy wouldn't just make an extremely light material, but a phenomenally stiff one as well... lighter and stronger than anything they could imagine. The team also observed that beryllium is an excellent absorber and conductor of heat, ...
Scientist who said climate change sceptics had been proved wrong accused of hiding truth by colleague

It was hailed as the scientific study that ended the global warming debate once and for all – the research that, in the words of its director, ‘proved you should not be a sceptic, at least not any longer’. Professor Richard Muller, of Berkeley University in California, and his colleagues from the Berkeley Earth Surface Temperatures project team (BEST) claimed to have shown that the planet has warmed by almost a degree centigrade since 1950 and is warming continually. Published last week ahead of a major United Nations climate summit in Durban, South Africa, next month, their work was cited around the world as irrefutable evidence that only the most stringent measures to ...

In this Friday, Oct. 28, 2011 photo, Richard Muller, left, and his daughter, Elizabeth Muller, hold a globe as they talk about their study on climate at their home in Berkeley, Calif. A new study of Earth’s temperatures going back more than 200 years finds the same old story: It’s gotten hotter in the last 60 years. What’s different is the scientist behind the latest study - Richard Muller. The California physicist was doubtful of what climate scientists have been saying - until he did his own research, partly funded by climate change skeptics. Elizabeth Muller, co-founder and executive director of the Berkeley Earth Surface Temperature Study, ran the study. WASHINGTON ...

‘Hide the Decline’ – Part Deux Here we go again. More questionable warmer data released, which only takes a short period of time to be discredited. Yet more unprecedented, irrefutable proof going down the global warming toilet. That this was touted as the “scientific study that ended the global warming debate once and for all” is laughable. From the Daily Mail we get this information: It was hailed as the scientific study that ended the global warming debate once and for all – the research that, in the words of its director, ‘proved you should not be a sceptic, at least not any longer’.

Sulphur dioxide dual bolster to post-harvest grape health A UWA research team has made the surprise discovery that sulphur dioxide (SO2) enhances grape berries’ natural defence system, making better able to fight off pathogens. Shiraz The sulphur dioxide provided an oxidative stress on the post-harvest grape berries and so strengthens their own defences. flickr: tannic teeth It was previously thought that sulphur dioxide—used as a preservative in dried fruits and winemaking—directly attacked the bacterial and fungal pathogens that cause spoilage. UWA School of Plant Biology, Assistant Professor Michael Considine who led the team says the sulphur dioxide provided an ...

"Every man desires to live long," wrote Jonathan Swift, "but no man would be old." Much has changed over the centuries, but the desire to retain youthful vigor during the golden years has endured. Fortunately, modern medicine has developed a plan for successful aging. It includes getting regular physical activity and mental stimulation; eating right; controlling blood pressure, cholesterol, and blood sugar levels; staying lean; building strong interpersonal relationships; and avoiding tobacco and other risky exposures and activities. A wise lifestyle can help extend life and slow the aging process - but it takes effort and discipline, especially for gents who have ...

Scientist Prove DNA Can Be Reprogrammed by Words and Frequencies By Grazyna Fosar and Franz Bludorf THE HUMAN DNA IS A BIOLOGICAL INTERNET and superior in many aspects to the artificial one. Russian scientific research directly or indirectly explains phenomena such as clairvoyance, intuition, spontaneous and remote acts of healing, self healing, affirmation techniques, unusual light/auras around people (namely spiritual masters), mind’s influence on weather patterns and much more. In addition, there is evidence for a whole new type of medicine in which DNA can be influenced and reprogrammed by words and frequencies WITHOUT cutting out and replacing single genes. Only 10% of our DNA ...
