SCienceDaily: Sep. 18, 2013 — Habitable conditions on Earth will be possible for at least another 1.75 billion years - according to astrobiologists at the University of East Anglia. Findings published today in the journal Astrobiology reveal the habitable lifetime of planet Earth - based on our distance from the sun and temperatures at which it is possible for the planet to have liquid water. The research team looked to the stars for inspiration. Using recently discovered planets outside our solar system (exoplanets) as examples, they investigated the potential for these planets to host life. The research was led by Andrew Rushby, from UEA's school of Environmental Sciences. ...

ScienceDaily: In a paper published today in the Proceedings of the National Academy of Sciences, co-authors Yi Cui, a materials scientist, Craig Criddle, an environmental engineer, and Xing Xie, an interdisciplinary fellow, call their invention a microbial battery. One day they hope it will be used in places such as sewage treatment plants, or to break down organic pollutants in the "dead zones" of lakes and coastal waters where fertilizer runoff and other organic waste can deplete oxygen levels and suffocate marine life. At the moment, however, their laboratory prototype is about the size of a D-cell battery and looks like a chemistry experiment, with two electrodes, one ...
Global Warming Warnings Called 'Gravely Flawed'

Global Warming Warnings Called 'Gravely Flawed' Six years ago, the BBC cited climate scientists in predicting that the Arctic would be ice-free in summer by 2013. Instead, Arctic ice this August covered nearly a million more square miles of ocean than in August 2012 — an increase of 60 percent. This has led Britain's Mail on Sunday to report: "Some eminent scientists now believe the world is heading for a period of cooling that will not end until the middle of the century — a process that would expose computer forecasts of imminent catastrophic warming as dangerously misleading." The newspaper also asserted that global warming had paused since the ...

Soldiers stalk through a ghostly, urban jungle of bombed-out buildings, approaching a pair of machine gun-toting enemies. “Ok. I see two tangoes ahead. The closer one…take him out first,” orders a gravelly voice, as a German shepherd leaps onto one of the targets. Blood spurts from the fallen enemy, as he cries out in pain. “Nice,” whispers the voice, as the soldier raises his machine gun to carefully sight the second of the two enemies. The machine gun roars to life as the viewer watches the enemy mortally fall through a series of well-placed head shots. If it all sounds like footage from an on-the-ground documentary out of the wars in Afghanistan, or Iraq, you ...

Arctic Sea Ice Up 60 Percent in 2013 Tuesday, 10 Sep 2013 03:29 PM By Melanie Batley An unusually cold Arctic summer has resulted in almost a million more square miles of ocean covered with ice compared to the same time last year, bucking predictions that global warming would result in the disappearance of the ice cap by 2013. According to the MailOnline, Arctic sea ice averaged 2.35 million square miles in August 2013 compared to the low point of 1.32 million square miles recorded in September 2012. "We are already in a cooling trend, which I think will continue for the next 15 years at least. There is no doubt the warming of the 1980s and 1990s has stopped," Anastasios ...

ScienceDaily... Sep. 12, 2013 — A genetic study has identified a biological process that influences whether we are right handed or left handed. Scientists at the Universities of Oxford, St Andrews, Bristol and the Max Plank Institute in Nijmegen, the Netherlands, found correlations between handedness and a network of genes involved in establishing left-right asymmetry in developing embryos. 'The genes are involved in the biological process through which an early embryo moves on from being a round ball of cells and becomes a growing organism with an established left and right side,' explained first author William Brandler, a PhD student in the MRC Functional Genomics Unit at ...

ScienceDaily...UC Irvine neurobiologists created new, specific memories by direct manipulation of the brain, which could prove key to understanding and potentially resolving learning and memory disorders. Research led by senior author Norman M. Weinberger, a research professor of neurobiology & behavior at UC Irvine, and colleagues has shown that specific memories can be made by directly altering brain cells in the cerebral cortex, which produces the predicted specific memory. The researchers say this is the first evidence that memories can be created by direct cortical manipulation. Study results appeared in the August 29 issue of Neuroscience. During the research, Weinberger and ...

LONDON (Reuters) - Scientists have succeeded in generating new stem cells in living mice and say their success opens up possibilities for the regeneration of damaged tissue in people with conditions ranging from heart failure to spinal cord injury. The researchers used the same "recipe" of growth-boosting ingredients normally used for making stem cells in a petri dish, but introduced them instead into living laboratory mice and found they were able to create so-called reprogrammed induced pluripotent stem cells (iPS cells). "This opens up new possibilities in regenerative medicine," said Manuel Serrano, who led the study at the Spanish National Cancer Research Centre ...

Michael Ferguson sometimes jokingly refers to himself among colleagues as "the other black brewer." That's because Ferguson, of the BJ's Restaurants group, is one of only a small handful of African-Americans who make beer for a living. Latinos and Asian-Americans are scarce within the brewing community, too. "For the most part, you've got a bunch of white guys with beards making beer," says Yiga Miyashiro, a Japanese-American brewer with Saint Archer Brewery in San Diego. Sure, there are prominent exceptions — like Garrett Oliver, the brewmaster at Brooklyn Brewery, and Celeste and Khouri Beatty, the owners and operators of Harlem Brewing Co. There ...

BEIJING, Sept. 7 (Xinhua) -- Chinese scientists have discovered that a type of H7N9 can bind with a human receptor, which explains how the virus can infect human beings. Research focused on how H7N9 infected human beings, examining the two earliest reported virus types, known as isolates. These were SH-H7N9 and AH-H7N9, discovered in Shanghai and Anhui province respectively. Researchers evaluated the viral hemagglutinin receptor binding properties of the two isolates. A receptor is a protein molecule in a cell, or on a cell, to which a substance can bind. A virus has to combine with a receptor in order to infect the host. Researchers found that SH-H7N9 (reported in Shanghai) ...
Left Brain vs. Right: It's a Myth, Research Finds

LiveScience... It's the foundation of myriad personality assessment tests, self-motivation books and team-building exercises – and it's all bunk. Popular culture would have you believe that logical, methodical and analytical people are left-brain dominant, while the creative and artistic types are right-brain dominant. Trouble is, science never really supported this notion. Now, scientists at the University of Utah have debunked the myth with an analysis of more than 1,000 brains. They found no evidence that people preferentially use their left or right brain. All of the study participants — and no doubt the scientists — were using their entire brain equally, ...

ScienceDaily Sep. 4, 2013 — No one knows for sure, but it is not at all unlikely that the universe is constructed in a very different way than the usual theories and models of today predict. The most widely used model today cannot explain everything in the universe, and therefore there is a need to explore the parts of nature which the model cannot explain. This research field is called new physics, and it turns our understanding of the universe upside down. New research now makes the search for new physics easier. Share This: "New physics is about searching for unknown physical phenomena not known from the current perception of the universe. Such phenomena are inherently very ...

Remembering to Remember: Two Routes of Memory Retrieval
Post Date: 2013-09-04 04:51:28 by Tatarewicz

When remembering to perform tasks in the future, 2 separate attentional brain processes appear equally successful in achieving the same outcome, a new study suggests. According to a popular theory, top-down attentional control is necessary in maintaining activation in prospective memory. For example, in trying to remember to take reusable bags to the grocery store, the top-down approach would involve constant reminders to oneself not to forget them. Another theory maintains that a bottom-up approach of spontaneous retrieval triggered by cues is effective. In the grocery bag scenario, such a cue might involve hanging the reusable bags from the front door knob as a reminder. In the ...

BBC... Miniature "human brains" have been grown in a lab in a feat scientists hope will transform the understanding of neurological disorders. The pea-sized structures reached the same level of development as in a nine-week-old foetus, but are incapable of thought. The study, published in the journal Nature, has already been used to gain insight into rare diseases. Neuroscientists have described the findings as astounding and fascinating. The human brain is one of the most complicated structures in the universe. Scientists at Institute of Molecular Biotechnology of the Austrian Academy of Sciences have now reproduced some of the earliest stages of the organ's development ...

ScienceAlert: Most strains of E.coli live quite happily in human and animal intestines, but some of these bacteria can cause diarrhoea as well as serious illnesses. There has been a small outbreak of E.coli infection in Brisbane. Three children and one adult who attended the Brisbane Royal Agricultural Show, also known as Ekka, tested positive for the bacterial infection last week. The children were apparently infected through direct contact with animals at the petting zoo. Another 13 cases have since come forward. The Queensland Health Department today confirmed eight cases of the Shiga toxin producing E.coli strain (STEC), with the age of those infected ranging from six to 42. Another ...

Cosmologist claims Universe may not be expanding Particles' changing masses could explain why distant galaxies appear to be rushing away. Jon Cartwright It started with a bang, and has been expanding ever since. For nearly a century, this has been the standard view of the Universe. Now one cosmologist is proposing a radically different interpretation of events — in which the Universe is not expanding at all. In a paper posted on the arXiv preprint server1, Christof Wetterich, a theoretical physicist at the University of Heidelberg in Germany, has devised a different cosmology in which the Universe is not expanding but the mass of everything has been increasing. Such an ...
