We're bombarded with information at all times, so much that if we had to try and process it all times, we'd be paralyzed. Our cerebellum does information damage control by filtering out what changes. Evolution made it possible for us to conserve energy while still processing anomalies quickly.
When the United States Environmental Protection Agency wrecked the ecosystem in Colorado, CEOs across the America likely had a private sentiment - if a corporation not being paid by the EPA had done it, they'd be in jail.
Sure enough, when the EPA caused toxic sludge to spill into a river, their bureaucrats assured us nature would fix itself.
New Haven, Conn.--The most effective prescription drug used to quit smoking initially helps women more than men, according to a Yale School of Medicine study.
The study, published Oct. 7 by the journal Nicotine and Tobacco Research, found that varenicline, marketed as Chantix, was more effective earlier in women, and equally effective in women and men after one year.
Back in February, General Mills announced that five varieties of gluten-free Cheerios (Apple Cinnamon, Frosted, Honey Nut, Multi Grain, and Original) would be available nationwide for purchase later in the year. With the launch of gluten-free Cheerios in recent months, General Mills embarked on one of the company's largest marketing offensives for cereal in many years.
It was great marketing, food is all about chasing the latest fads. But it was not without missteps. On October 5th they recalled 1.8 million boxes of original and Honey Nut Cheerios labeled gluten-free because they contained wheat and the U.S. Food and Drug Administration (FDA) had received 125 complaints from consumers who ate gluten-free Cheerios and experienced gastrointestinal problems.
Fresh research at Sahlgrenska Academy has found that antioxidants can double the rate of melanoma metastasis in mice. The results reinforce previous findings that antioxidants hasten the progression of lung cancer. According to Professor Martin Bergö, people with cancer or an elevated risk of developing the disease should avoid nutritional supplements that contain antioxidants.
Researchers at Sahlgrenska Academy, University of Gothenburg, demonstrated in January 2014 that antioxidants hastened and aggravated the progression of lung cancer. Mice that were given antioxidants developed additional and more aggressive tumors. Experiments on human lung cancer cells confirmed the results.
Scientists writing in Environmental Research Letters estimate that the onset of spring plant growth will shift by a median of three weeks over the next century - and global warming is to blame.
The scholars from University of Wisconsin-Madison applied the extended Spring Indices to predict the dates of leaf and flower emergence based on day length. These general models capture the phenology of many plant species. Their results show particularly rapid shifts in plant phenology in the Pacific Northwest and Mountainous regions of the western US, with smaller shifts in southern areas, where spring already arrives early. Much of their data is available at http://silvis.forest.wisc.edu/
Researchers have developed a new strategy for helping African farmers fight a parasitic plant that devastates crops - plants in the genus Striga, also known as witchweed.
Though their purple flowers are pretty to look at, a field full of Striga plants is in fact a nightmare for a farmer who wants to grow corn, sorghum, rice or other subsistence crops. The problem affects more than 100 million people across 25 countries in sub-Saharan Africa.
University of Toronto chemical engineering professor Alexei Savchenko, along with professor Peter McCourt in the Department of Cell and Systems Biology, have created a genetically engineered plant biosensor, a tool that will help them hunt for molecules that could prevent Striga infestations.
By meticulously examining sediments in China's Yellow River, a Swedish-Chinese research group are showing that the history of tectonic and climate evolution on Earth may need to be rewritten. Their findings are published today in the highly reputed journal Nature Communications.
To reconstruct how the global climate and topography of the Earth's surface have developed over millions of years, deposits of eroded land sediment transported by rivers to ocean depths are often used. This process is assumed to have been rapid and, by the same token, not to have resulted in any major storages of this sediment as large deposits along the way.
A new paper gives psycholgists a unique glimpse at how humans develop an ability to use tools in childhood while nonhuman primates--such as capuchin monkeys and chimpanzees--remain only occasional tool users.
Dorothy Fragaszy, a psychology professor at the University of Georgia, created two studies to look at how non-human primates and human children differ in completing simple spatial reasoning tasks.
Much like a game of Operation, human children ages 2, 3 and 4 and adult nonhuman primates were asked to fit a stick, a cross and a tomahawk into a matching cutout space on a tray. Children were also given an opportunity to complete this task by placing the sticks on a mat with a drawing of the matching shape, as well as into a space on a tray.
Renewable energy is not very sustainable in the European Union (EU) yet but the food industry, which is heavily reliable on subsidies to stay competitive with the rest of the world, needs renewable energy costs to come down to remain viable.
Until then, the food sector is going to resist using renewable energy, which is a scant 7 percent of their usage, compared to 15 percent in the EU overall. Instead of advocating basic research to improve renewable energy, the call is out to lower meat consumption in a new report. And of course to reduce food choices by shopping locally and seasonally.
Osteoporosis, a disease of progressive bone loss, affects 70 percent of the U.S. population older than age 50 - about 50 percent of women and 20 percent of men. These individuals are at risk for fragility fractures, a break that results from a fall, or occurs in the absence of obvious trauma, and most commonly seen in the wrist, the upper arm, the hip, and the spine.
People who sustain a fragility fracture are at a higher risk for future fractures and face increasing treatment costs. According to a new study, anti-osteoporotic therapy, a treatment intended to increase bone mineral density and slow or stop the loss of bone tissue, can decrease the risk of subsequent fractures by 40 percent.
A course on critical thinking has generated a new proposal to remove sources of bias in research and improve confidence in published studies.
Social science research got a black eye recently when the authors of several studies were shown to have manipulated data. But the more prevalent issue in the social sciences today is not actual fraud, but subtle and usually inadvertent bias that skews the conclusions of studies and often makes them unrepeatable.
Pioneering new research sheds light on the impact of climate change on subglacial lakes found under the Greenland ice sheet.
A team of experts, led by Dr Steven Palmer from the University of Exeter, has studied the water flow paths from one such subglacial lake, which drained beneath the ice sheet in 2011.
The study shows, for the first time, how water drained from the lake - via a subglacial tunnel. Significantly, the authors present satellite observations that show that a similar event happened in 1995, suggesting that this lake fills and drains periodically.
The study, called Subglacial lake drainage detected beneath the Greenland Ice Sheet is published in the journal Nature Communications.
