NASA data shows surfer-shaped waves in near-Earth space

July 8, 2015 - 4:53pm
The universe overflows with repeating patterns. From the smallest cells to the largest galaxies, scientists are often rewarded by observing similar patterns in vastly different places. One such pattern is the iconic surfer's waves seen on the ocean - a series of curled hills moving steadily in one direction. The shape has a simple cause. A fast fluid, say wind, moving past a slower one, say water, naturally creates this classic shape. Named Kelvin-Helmholtz waves in the late 1800s after their discoverers, these waves have since been discovered all over the universe: in clouds, in the atmospheres of other planets, and on the sun. Now two recently published papers highlight these shapely waves at the boundaries of near-Earth space.

Hibernating bears protect bones by reducing resorption

July 8, 2015 - 4:00pm
Even a short period of inactivity can be extremely bad for our bones, and for astronauts facing months in zero gravity, the risks are serious. But there is an animal that has already solved all of the problems faced by immobile humans. Black bears routinely hibernate for 6 months without stirring, and although it can take several weeks for them to regain their full metabolic vigour, their bones seem largely unaffected by the lengthy period of inactivity. Yet, how these impressive beasts protect their bones was a mystery, with previous studies yielding contradictory results.

Diving dolphins are exhalation champions

July 8, 2015 - 4:00pm
Every air-breathing marine mammal faces a multitude of challenges as it dives beneath the waves: carbon dioxide and nitrogen accumulation in the blood can cause intoxication and decompression sickness, while low internal pressures in rigid lungs can force blood into the delicate airways. Yet, whales, dolphins and seals rarely seem to suffer these ill effects. Andreas Fahlman from Texas A&M University - Corpus Christi, USA, says, 'It had been assumed that the respiratory systems of all marine mammals are similar with a stiff upper airway and collapsible lungs'. However, there was little evidence to support the assumption and Fahlman was repeatedly told that the measurements couldn't be made because of the incredibly high flow rates generated by exhaling dolphins.

Chameleons' eyes are not so independent

July 8, 2015 - 4:00pm
Famed for their ability to change colour, chameleons have yet another mind-boggling talent: their eyes appear to swivel completely independently. This means that they can simultaneously track two completely different views of the world, which is quite impressive from our primate perspective.

'Straintronic spin neuron' may greatly improve neural computing

July 8, 2015 - 1:30pm
(Phys.org)—Researchers have proposed a new type of artificial neuron called a "straintronic spin neuron" that could serve as the basic unit of artificial neural networks—systems modeled on human brains that have the ability to compute, learn, and adapt. Compared to previous designs, the new artificial neuron is potentially orders of magnitude more energy-efficient, more robust against thermal degradation, and fires at a faster rate.

New horned dinosaur reveals evolution of nose horn in Triceratops family

July 8, 2015 - 12:00pm
Scientists have discovered a striking new species of horned dinosaur (ceratopsian) based on fossils collected from a bone bed in southern Alberta, Canada. Wendiceratops (WEN-dee-SARE-ah-TOPS) pinhornensis was approximately 6 meters (20 feet) long and weighed more than a ton. It lived about 79 million years ago, making it one of the oldest known members of the family of large-bodied horned dinosaurs that includes the famous Triceratops, the Ceratopsidae. Research describing the new species is published online in the open access journal, PLOS ONE.

Remediating abandoned, inner city buildings reduces crime and violence in surrounding area

July 8, 2015 - 12:00pm
Fixing up abandoned buildings in the inner city doesn't just eliminate eyesores, it can also significantly reduce crime and violence, including gun assaults, researchers from the University of Pennsylvania and Penn's Perelman School of Medicine report in the first study to demonstrate the direct impact of building remediation efforts on crime. The findings were published this week in the journal PLOS ONE.

World record: Most powerful high-energy particle beam for a neutrino experiment ever generated

July 8, 2015 - 11:44am
A key element in a particle-accelerator-based neutrino experiment is the power of the beam that gives birth to neutrinos: The more particles you can pack into that beam, the better your chance to see neutrinos interact in your detector. Today scientists announced that Fermilab has set a world record for the most powerful high-energy particle beam for neutrino experiments.

NASA sees Tropical Storm Linfa approaching southeastern China coast

July 8, 2015 - 11:35am
NASA's Aqua satellite provided a bird's eye view of Tropical Storm Linfa as it was approaching the southeastern China coast on July 8. NASA's RapidScat instrument found that the typhoon's strongest winds were on its eastern side toward Taiwan and away from China. Both countries have posted warnings on July 8.
