Physicists Confirm Existence of New Particle
Post Date: 2011-07-23 23:44:09 by Tatarewicz

Physicists working at Fermilab’s particle accelerator have confirmed the observation of an entirely new particle — the the Xi-sub-b baryon. Baryons are particles formed of three quarks, in different configurations. The proton is a baryon that consists of two up and one down quark, and the neutron is two down and one up. The Xi-sub-b has an up quark, a strange quark (yes, that’s its real name) and a heavy bottom quark (again, real name), meaning that it weighs around six times as much as a proton or neutron. Its existence has been predicted for some time, but hadn’t previously been observed. It doesn’t stick around long, though — traveling a fraction of a ...

Mozambique has exported its first batch of biofuel produced from the jatropha plant for use by the German airline Lufthansa, a company official told AFP on Friday. Oil crushed from non-edible seeds from the drought resistant and fast growing plant are produced in the central province of Manica by British company Sun Biofuels which has sent 30 tons to Germany. "The world market is demanding huge quantities of bio-fuel," the firm's director of corporate affairs Sergio Gouveia told AFP. "Luftansa alone is seeking 400 million litres per year of bio-fuel across the world." He did not reveal how much they had been paid for the shipment, but said biofuel prices vary ...
Scientists identify seventh and eighth bases of DNA
Post Date: 2011-07-23 21:27:29 by Tatarewicz

For decades, scientists have known that DNA consists of four basic units -- adenine, guanine, thymine and cytosine. Those four bases have been taught in science textbooks and have formed the basis of the growing knowledge regarding how genes code for life. Yet in recent history, scientists have expanded that list from four to six. Now, with a finding published online in the July 21, 2011, issue of the journal Science, researchers from the UNC School of Medicine have discovered the seventh and eighth bases of DNA. These last two bases – called 5-formylcytosine and 5 carboxylcytosine – are actually versions of cytosine that have been modified by Tet proteins, molecular entities ...

This is the first time light-induced evaporation has been shown to occur in diamonds. In a paper published in the US journal Optical Materials Express this week, Macquarie University researchers show that even the earth's hardest naturally occurring material, the diamond, is not forever. Associate Professor Richard Mildren and his colleagues from the Macquarie University Photonics Research Centre discovered that diamonds evaporate under exposure to light. "Although this type of light-induced evaporation has been observed in some materials, this is the first time it's been shown to occur for diamond," Mildren said. The diamonds were exposed to intense light pulses in ...

Half of the extraordinary heat of the Earth that erupts on its surface volcanically and drives the titanic motions of the continents is due to radioactivity, scientists find. This new discovery shows that the planet still retains an extraordinary amount of heat it had from its primordial days. To better understand the sources of the Earth's heat, scientists studied antineutrinos, elementary particles that, like their neutrino counterparts, only rarely interact with normal matter. Using the Kamioka Liquid-scintillator Antineutrino Detector (KamLAND) located under a mountain in Japan, they analyzed geoneutrinos — ones emitted by decaying radioactive materials within the Earth ...

The widespread use of search engines and online databases has affected the way people remember information, researchers are reporting. The scientists, led by Betsy Sparrow, an assistant professor of psychology at Columbia, wondered whether people were more likely to remember information that could be easily retrieved from a computer, just as students are more likely to recall facts they believe will be on a test. Dr. Sparrow and her collaborators, Daniel M. Wegner of Harvard and Jenny Liu of the University of Wisconsin, Madison, staged four different memory experiments. In one, participants typed 40 bits of trivia — for example, “an ostrich’s eye is bigger than its ...

A team of Japanese scientists have created complete tooth units by using mouse stem cells and successfully transplanted them into mice. The tooth units, which also contain connective fibers and bones, were attached successfully to the lower jaw bones, and helped the rats to chew normally, researchers wrote in PLoS One. As the first step, researchers isolated two types of stem cells from the molar teeth of mice and grew them in the laboratory. The cells formed a tiny "tooth bud" within five days, which were then placed in a mold. The primary structures were then placed inside the body of the mouse until a complete tooth unit was formed. "The bioengineered teeth were ...

The US space agency says its Dawn probe should go into orbit around the Asteroid Vesta early on Saturday (GMT). The robotic satellite will be spending a year at the 530km-wide body before moving on to the "dwarf planet" Ceres. New pictures on Dawn's approach to Vesta show the giant rock in unprecedented detail. The asteroid looks like a punctured football, the result of a colossal collision sometime in its past that knocked off its south polar region. Dawn's encounter is occurring about 188 million km (117 million miles) from Earth. Engineers have put the spacecraft on a course to be captured in the gravitational field of Vesta. They expect to hear confirmation from ...

SINGAPORE, July 13 (Xinhua) -- A team of researchers at Singapore's Nanyang Technological University have developed a special anti-rust coating for metals, local Channel NewsAsia reported on Wednesday. The coating contains microscopic capsules with chemicals highly reactive to water. When the coating is scratched, the micro- capsules break and release the chemicals, creating a "self-healing " effect. The chemicals react with water or moisture to form a plastic- like sealant over the scratch, preventing corrosion. Yang Jinglei, an assistant professor who led the research, said corrosion losses can be up to five percent of a country's gross domestic product. ...
