Iceland Stands Down On Travel Alert: From Orange To Red and Back Again

Slashdot - Sun, 24/08/2014 - 9:06pm
Iceland's tiered system of air travel alerts went to orange last week, then to red with a believed under-ice eruption of the volcano beneath the Dyngjujokull glacier, but has now been eased back to orange. "Observations show that a sub-glacial eruption did not occur yesterday. The intense low-frequency seismic signal observed yesterday has therefore other explanations," the Icelandic Met Office said. The office had therefore decided to move the aviation warning code from red to orange, it said, but since there was no sign the seismic activity was slowing down, an eruption could still not be excluded. The national police commissioner said separately that all restrictions on aviation had been cancelled. Airspace of 140 by 100 nautical miles above the volcano had been closed to aircraft on Saturday.

Slashdot Asks: How Prepared Are You For an Earthquake?

Slashdot - Sun, 24/08/2014 - 8:06pm
With three earthquakes of some significance in the news this weekend (Chile, California, and Iceland), it seems a good time to ask: If you live in an area of seismic danger, how are you prepared for an earthquake (or tsunami, mudslide, or other associated danger) and how prepared are you? Do you have a stash of emergency supplies, and if so, how did you formulate it? In the U.S. alone, it's surprising how many areas there are with some reasonable chance of earthquakes, though only a few of them are actually famous for it — and those areas are the ones where everything from building codes to cultural awareness helps mitigate the risks. I'm not sure I'd want to be in a skyscraper in Memphis or St. Louis during a replay of the New Madrid quakes of 1811-1812, which is probably worth worrying about for those in the region. Beyond personal safety, do you have a plan for your electronics and data if the earth starts shaking?

'Just right' plant growth may make river deltas resilient

Science Daily - Sun, 24/08/2014 - 7:23pm
Geologists suggest that an intermediate amount of vegetation -- not too little and not too much -- is most effective at stabilizing freshwater river deltas. Vegetation on marsh surfaces in river deltas can slow the flow of water and cause more sediment to be deposited, helping prevent sea-level rise from drowning sensitive marshlands. But the study finds that, if the vegetation is too tall or dense, it diverts water into the river channel, resulting in less sediment being deposited on the marsh.

Neuroscience and big data: How to find simplicity in the brain

Science Daily - Sun, 24/08/2014 - 7:23pm
Scientists can now monitor and record the activity of hundreds of neurons concurrently in the brain, and ongoing technology developments promise to increase this number. However, simply recording the neural activity does not automatically lead to a clearer understanding of how the brain works. In a new article, researchers describe the scientific motivations for studying the activity of many neurons together, along with a class of machine learning algorithms for interpreting the activity.

Haven't my neurons seen this before? What happens in the brain with familiar pictures?

Science Daily - Sun, 24/08/2014 - 7:23pm
The world grows increasingly more chaotic year after year, and our brains are constantly bombarded with images. A new study reveals how neurons in the part of the brain responsible for recognizing objects respond to being shown a barrage of images. Researchers found that when subjects were exposed to familiar and unfamiliar images in a rapid succession, their neurons -- especially the inhibitory neurons -- fired much more strongly and selectively to images the subject had seen many times before.

Are you as old as what you eat? Researchers learn how to rejuvenate aging immune cells

Science Daily - Sun, 24/08/2014 - 7:23pm
Researchers have demonstrated how an interplay between nutrition, metabolism and immunity is involved in the process of aging. It has been suspected for a long time that these are linked, and this paper provides a prototype mechanism of how nutrient and senescence signals converge to regulate the function of T lymphocytes.

Bioengineers close to brewing opioid painkillers without using opium from poppies

Science Daily - Sun, 24/08/2014 - 7:23pm
A process that uses genetically engineering yeast cells to replicate the entire opioid production process, eliminating the need to grow poppies, is close to conclusion, one researcher reports. Her ultimate goal is to produce opioid medicines, from start to finish, in fermentation vats.

Driving brain rhythm makes mice more sensitive to touch

Science Daily - Sun, 24/08/2014 - 7:23pm
In a new study researchers show that they could make faint sensations more vivid by triggering a brain rhythm that appears to shift sensory attention. The study in mice provides the first direct evidence that the brain's 'gamma' rhythms have a causal role in processing the sense of touch.

Cutting emissions pays for itself, study concludes

Science Daily - Sun, 24/08/2014 - 7:23pm
Health care savings can greatly defray costs of carbon-reduction policies, experts report. But just how large are the health benefits of cleaner air in comparison to the costs of reducing carbon emissions? Researchers looked at three policies achieving the same reductions in the U.S., and found that the savings on health care spending and other costs related to illness can be big -- in some cases, more than 10 times the cost of policy implementation.

Repurposing anti-depressant medication to target medulloblastoma

Science Daily - Sun, 24/08/2014 - 7:23pm
A novel molecular pathway that causes an aggressive form of medulloblastoma has been identified by researchers. Now scientists suggest repurposing an anti-depressant medication to target medulloblastoma to help combat one of the most common brain cancers in children. The scientists say their laboratory findings in mouse models of the disease could lead to a more targeted and effective molecular therapy that would also reduce the harmful side effects of current treatments.

Mimicking natural evolution with 'promiscuous reactions' to improve the diversity of drugs

Science Daily - Sun, 24/08/2014 - 7:23pm
A revolutionary new scientific method will improve the diversity of 'biologically active molecules', such as antibiotics and anti-cancer agents. "Nature produces some amazing structures with really interesting biological activity, but the plant or animal did not design them. Instead the organisms gradually evolved both the chemical structures and the methods to produce them over millennia because they were of benefit. We wanted to capture the essence of this in our approach to discovering new drugs," said the lead author.
