PressTV A new study conducted by American researchers suggests that children’s afternoon short sleep gives them better learning power. The new study shows that naps are critical for memory consolidation and early learning among kids particularly for those who are three to-five-year-olds. Sleep researchers at the University of Massachusetts Amherst say an hour-long nap after lunch boosts brain power and memory in preschool children. As the children napped, they experienced increased activity in brain spots linked with learning and integrating new information, according to the findings published in Proceedings of the National Academy of Sciences. "Our study shows that naps ...

ScienceDaily Sep. 24, 2013 — Humans and other mammals show particularly intensive sleeping patterns during puberty. The brain also matures fastest in this period. But when pubescent rats are administered caffeine, the maturing processes in their brains are delayed. This is the result of a study supported by the Swiss National Science Foundation (SNSF). Children's and young adults' average caffeine consumption has increased by more than 70 per cent over the past 30 years, and an end to this rise is not in sight: the drinks industry is posting its fastest-growing sales in the segment of caffeine-laden energy drinks. Not everybody is pleased about this development. Some people ...

Science Daily Sep. 23, 2013 — The Institute for Solar Energy Systems ISE, Soitec, CEA-Leti and the Helmholtz Center Berlin jointly announced today having achieved a new world record for the conversion of sunlight into electricity using a new solar cell structure with four solar subcells. Surpassing competition after only over three years of research, and entering the roadmap at world class level, a new record efficiency of 44.7% was measured at a concentration of 297 suns. This indicates that 44.7% of the solar spectrum's energy, from ultraviolet through to the infrared, is converted into electrical energy. This is a major step towards reducing further the costs of solar ...

The "Fast Food Nation" author on his frightening new exposé of America's nuclear weapons mishaps. The term "wake-up call" is a tired cliché, but it is appropriate in the case of Command and Control, the frightening new exposé of America's nuclear weapons mishaps by Fast Food Nation author Eric Schlosser. (Click here to read an excerpt and my detailed review.) In short, Schlosser delivers a book full of revelations that left me agape. While we still worry in the abstract about Iran and North Korea and Pakistan, it's easy to forget that we still have thousands of our own ungodly devices on hair-trigger alert at this very moment. And even ...

Neandertals made the first specialized bone tools in Europe Edited by Erik Trinkaus, Washington University, St. Louis, MO, and approved May 22, 2013 (received for review February 12, 2013) Abstract Modern humans replaced Neandertals ∼40,000 y ago. Close to the time of replacement, Neandertals show behaviors similar to those of the modern humans arriving into Europe, including the use of specialized bone tools, body ornaments, and small blades. It is highly debated whether these modern behaviors developed before or as a result of contact with modern humans. Here we report the identification of a type of specialized bone tool, lissoir, previously only associated with modern humans. The ...

Solar activity drops to 100-year low, puzzling scientists Reuters | Sep 18, 2013, 10.51 PM IST LONDON: Predictions that 2013 would see an upsurge in solar activity and geomagnetic storms disrupting power grids and communications systems have proved to be a false alarm. Instead, the current peak in the solar cycle is the weakest for a century. Subdued solar activity has prompted controversial comparisons with the Maunder Minimum, which occurred between 1645 and 1715, when a prolonged absence of sunspots and other indicators of solar activity coincided with the coldest period in the last millennium. The comparisons have sparked a furious exchange of views between observers who believe the ...
Equinox Arrives September 22nd

Why is the time of the equinox so specific? S&T's editors explain. For those of us already seeing blushing foliage or feeling a chill in the air, it might seem as though autumn has already arrived. But astronomically speaking, fall officially comes to Earth's Northern Hemisphere at 20:44 Universal Time on Sunday, September 22, 2013. At that moment, the Sun's path crosses Earth's equator heading south, an event called the autumnal equinox. Why do we say summer ends and fall begins at an exact moment, when the natural events happen gradually? Because the four seasons many of us use — winter, spring, summer, and fall — have beginning and ending points defined as ...

ScienceDaily Sep. 21, 2013 — The sweep of a needle across the grooves of a worn vinyl record carries distinct sounds: hisses, scratches, even the echo of skips. For many years, though, those yearning to hear Frank Sinatra sing "Fly Me to the Moon" have been able to listen to his light baritone with technical clarity, courtesy of the increased signal-to-noise ratio of digital remasterings. Now, with advances in neurofeedback techniques, the signal-to-noise ratio of the brain activity underlying our thoughts can be remastered as well, according to a recent discovery in the Proceedings of the National Academy of Sciences by a research team led by Stephen LaConte, an assistant ...

Scientists believe they have found the first evidence of life arriving to Earth from space, which could “completely change our view of biology and evolution”. The team, from the University of Sheffield, made the discovery after sending a balloon high into the stratosphere. On its return they found organisms that were too large to have originated from Earth. Professor Milton Wainwright, who led the team, said the results could be revolutionary. “If life does continue to arrive from space then we have to completely change our view of biology and evolution,” he said. “In the absence of a mechanism by which large particles like these can be transported to the ...

Food waste gets the high-tech treatment at Aflac with ORCA machine later. Composting is a great way to deal with food waste naturally, but there's an even faster method that can convert solid waste into nutrient-rich greywater — and do it within 24 hours. The ORCA Green Machine is a high-tech waste digester that's now in use at the Aflac cafeteria to keep thousands of pounds of waste from ending up in landfills each year. Aflac has a corporate goal to recycle at least 75 percent of its solid waste. Now, with the ORCA Green Machine, the company can recycle its food waste, too. In this video, Aflac employees discuss how the ORCA machine works, and the impact that it can have on ...

Increasing Number of British Public Deny World's Climate is Changing Friday, 20 Sep 2013 04:39 PM By Sandy Fitzgerald The world's climate is not changing, more than one-fifth of the British public believe, according to a survey from the UK Energy Research Centre. The findings come as scientists continue their work on a United Nation's report on the impact of climate change. The poll was done as part of a larger survey concerning changing attitudes toward nuclear power, and showed that people are less willing to accept new nuclear power stations because they don't think climate change is occurring. The survey showed that just under 75 percent of the British public still ...

30,000 scientists, including the founder of The Weather Channel, have come forward to sue former US Vice President Al Gore for fraud, alleging that he made massive profits in the promotion of the global warming mythology. They scientists are hoping the lawsuit will finally give the thousands of 'dissenting' scientists a voice again. Environmentalism has been politically linked to alternative medicine for many years, due to the unfortunate pervasive presence of the paganistic religions. It is truly a tragic situation that has impeded alternative medicine in the U.S. perhaps as much as any other factor. At The Health Wyze Report, scientists believe that reducing human harm to the ...

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. ...

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 ...
