Spike in carbon-14 levels indicates a massive cosmic event — but supernovae and solar flares ruled out. Just over 1,200 years ago, the planet was hit by an extremely intense burst of high-energy radiation of unknown cause, scientists studying tree-ring data have found. The radiation burst, which seems to have hit between ad 774 and ad 775, was detected by looking at the amounts of the radioactive isotope carbon-14 in tree rings that formed during the ad 775 growing season in the Northern Hemisphere. The increase in 14C levels is so clear that the scientists, led by Fusa Miyake, a cosmic-ray physicist from Nagoya University in Japan, conclude that the atmospheric level of 14C must ...

You’ve probably heard of Dolly the sheep, the world’s first cloned mammal. But you’ve probably never heard of Tiny the mouse...one of the first creatures ever created from “reprogrammed” adult cells. Don’t be fooled by this little mouse’s name, what Tiny represents in the world of regenerative medicine is anything but tiny... In July 2009, a team from the Beijing’s Institute of Zoology reported in the journal Nature that it created healthy, fertile animals (Tiny and its brethren) by using so-called pluripotent stem cells (iPS). IPS cells are adult cells that have been genetically reprogrammed back to a pluripotent state. A pluripotent cell is simply ...

ScienceDaily (June 13, 2012) — Scientists agree that carbon dioxide (CO2) has an effect on global warming as a greenhouse gas, but we still pump tons and tons of CO2 into the atmosphere every day. A research team at the Freiburg Materials Research Center (FMF) led by the chemist Prof. Dr. Ingo Krossing has now developed a new system for producing methanol that uses CO2 and hydrogen. Methanol can, for example, be used as an environmentally friendly alternative for gasoline. The goal of the scientists is to harness the power of CO2 on a large scale and integrate it into the utilization cycle as a sustainable form of energy production. In order to produce methanol, Krossing's ...
Early experience prunes brain wiring

ScienceDaily (June 6, 2012) — New research shows mice brains are 'very wired up' at birth, and suggests experience selects which connections to keep. Ask the average person the street how the brain develops, and they'll likely tell you that the brain's wiring is built as newborns first begin to experience the world. With more experience, those connections are strengthened, and new branches are built as they learn and grow. A new study conducted in a Harvard lab, however, suggests that just the opposite is true. As reported on June 7 in the journal Neuron, a team of researchers led by Jeff Lichtman, the Jeremy R. Knowles Professor of Molecular and Cellular Biology, ...

Calibrate your mouse Funny, but I never knew this even after all these years of using my personal computer. MOUSE CALIBRATION: You should actually do this every year. Even more often if you spend a lot of time on the computer. This was recommended by Kim Komando (the computer guru) in one of her recent emails. I was surprised to see how well it works, and how far off mine was. To re-calibrate your mouse, click and hold on the capital S below, then drag it toward the small g. If it doesn't work immediately, you might want to clean your mouse, as the calibration is off. Shit! You'll believe anything
Molecular Imaging Finds Link Between Low Dopamine Levels and Aggression

ScienceDaily (June 11, 2012) — Out of control competitive aggression could be a result of a lagging neurotransmitter called dopamine, say researchers presenting a study at the Society of Nuclear Medicine's 2012 Annual Meeting. During a computer game against a putative cheating adversary, participants who had a lower capacity to synthesize this neurotransmitter in the brain were more distracted from their basic motivation to earn money and were more likely to act out with aggression. For many people, anger is an almost automatic response to life's challenges. In clinical psychiatry, scientists look at not only the impact of aggressive behavior on the individual, their loved ...

New primitive primate unearthed in Myanmar Fossil highlights critical step in primate evolution Lee Flohr From just four teeth, an international team of researchers have identified a new species of anthropoid primate – the ancestors of humans, apes and monkeys – that’s approximately 37-million years old. Weighing barely 100 grams – about as much as a small stick of butter – and unearthed at the Pondaung Formations of Myanmar, Afrasia djijidae may help bridge primate migration from Asia to Africa. “We’ve found nearly the same taxa in both Asia and Africa,” Jean-Jacques Jaeger, study co-author and paleontologist at the University of Poitiers in ...

ScienceDaily (June 6, 2012) — The dramatic melt-off of Arctic sea ice due to climate change is hitting closer to home than millions of Americans might think. That's because melting Arctic sea ice can trigger a domino effect leading to increased odds of severe winter weather outbreaks in the Northern Hemisphere's middle latitudes -- think the "Snowmageddon" storm that hamstrung Washington, D.C., during February 2010. Cornell's Charles H. Greene, professor of earth and atmospheric sciences, and Bruce C. Monger, senior research associate in the same department, detail this phenomenon in a paper published in the June issue of the journal Oceanography. ...
Japan team create liver from stem cells: report

Japanese researchers have created a functioning human liver from stemcells, a report said Friday, raising hopes for the manufacture of artificial organs for those in need of transplants. A team of scientists transplanted induced pluripotent stem (iPS) cells into the body of a mouse, where it grew into a small, but working, human liver, the Yomiuri Shimbun said. Stemcells are frequently harvested from embryos, which are then discarded, a practice some people find morally objectionable. But iPS cells -- which have the potential to develop into any body tissue -- can be taken from adults. A team led by professor Hideki Taniguchi at Yokohama City University developed human iPS cells into ...
Bee-killing virus gets supercharged by mites

LONDON, June 7, 2012 (Reuters) — Parasitic mites have turbo-charged the spread of a virus responsible for a rise in honey bee deaths around the world, scientists said on Thursday. Bee populations have been falling rapidly in many countries, fuelled by a phenomenon known as colony collapse disorder. Its cause is unclear but the Varroa mite is a prime suspect, since it spreads viruses while feeding on hemolymph, or bee's "blood". To clarify the link between mites and viruses, a team led by Stephen Martin of Britain's University of Sheffield studied the impact of Varroa in Hawaii, which the mites have only recently invaded. They found the arrival of Varroa increased ...

ScienceDaily (June 4, 2012) — A new Purdue University-developed process for creating biofuels has shown potential to be cost-effective for production scale, opening the door for moving beyond the laboratory setting. A Purdue economic analysis shows that the cost of the thermo-chemical H2Bioil method is competitive when crude oil is about $100 per barrel when using certain energy methods to create hydrogen needed for the process. If a federal carbon tax were implemented, the biofuel would become even more economical. H2Bioil is created when biomass, such as switchgrass or corn stover, is heated rapidly to about 500 degrees Celcius in the presence of pressurized hydrogen. Resulting ...

The Peak Oil Crisis: The Edisonian Approach By Tom Whipple Wednesday, May 30 2012 12:50:29 PM While waiting to see if Greece leaves the Eurozone, Spain collapses, and the Iranians can get their act together, it is a good time to discuss some of the recent developments on the Low Energy Nuclear Reactions (LENR) front. There is still no definitive word on whether commercial scale production of cheap and clean energy will be available in time to save us from unaffordable fossil fuels, global warming, economic collapse and whatever else seems destined to make life on earth rather uncomfortable, but claims of progress and circumstantial evidence that the phenomenon is for real continues to ...
