Meteorite study indicates volcanic activity on early small asteroids

(Phys.org) —Examination of one of the Almahata Sitta meteorites (aka, ALM-A, found in Sudan in 2008) by a team of space scientists working in Germany has revealed a volcanic past. In their paper published in Proceedings of the National Academy of Sciences, the team describes how they dated the meteorite to just a few million years after our solar system was born and uncovered evidence that it suggests it was produced by volcanic activity.

GPIM spacecraft to validate use of "green" propellant

Two dynamos drive Jupiter's magnetic field

(Phys.org) —Superlatives are the trademark of the planet Jupiter. The magnetic field at the top edge of the cloud surrounding the largest member of the solar system is around ten times stronger than Earth's, and is by far the largest magnetosphere around a planet. Just why this field has a similar structure to that of our own planet although the interiors of the two celestial objects have a completely different structure, has mystified researchers for a long time. With the aid of the most detailed computer simulations to date, a team headed by the Max Planck Institute for Solar System Research in Göttingen has now succeeded in explaining the origin of the magnetic field deep inside the gaseous giant.

Technology news

Michigan team finds security flaws in traffic lights

What if attackers could manipulate traffic lights so that accidents would happen with mayhem as the result? That is a question many would rather put off for another day but authorities feeling responsible for road safety are generally willing to consider all the what-ifs, assess their impact, and look for protective measures. According to a detailed report in Tuesday's MIT Technology Review, a road agency gave Michigan researchers permission to hack into almost 100 wirelessly networked traffic lights. The real news is what this electrical engineering and computer science team from the University of Michigan discovered. They saw three troubling weaknesses in the traffic light system they studied: unencrypted wireless connections, the use of default usernames and passwords that can be found online, and a debugging port easy to attack. Who is to blame? In their paper, "Green Lights Forever: Analyzing the Security of Traffic Infrastru! cture," which they will present at a computer security conference, they said no single device or design choice is at fault; the weaknesses instead "show a systemic lack of security consciousness.".

New algorithm lets drones monitor their own health during long package-delivery missions

In the near future, the package that you ordered online may be deposited at your doorstep by a drone: Last December, online retailer Amazon announced plans to explore drone-based delivery, suggesting that fleets of flying robots might serve as autonomous messengers that shuttle packages to customers within 30 minutes of an order.

Security event to learn about side-channel attacks on PCs

A paper to be presented at next month's Workshop on Cryptographic Hardware and Embedded Systems (CHES) in Busan, South Korea, will discuss physical side-channel attacks on laptop computers, in findings from a team from the Technion and Tel Aviv University. "We demonstrated physical side-channel attacks on a popular software implementation of RSA and ElGamal, running on laptop computers," they said, using novel side channels. They said their attacks were based on the observation that the ground electric potential in many computers fluctuates in a computation-dependent way. An attacker can measure the signal by touching exposed metal on the computer chassis with a plain wire or even with a bare hand. The signal can also be measured at the remote end of Ethernet, VGA or USB cables They noted "non-negligible" impedance between the grounding point(s) and other points in the chassis. "Due to currents and electromagnetic fields inside the computer, voltages of large magnitude develop across this impedance (often 10mV RMS or more, after filtering out the 50 or 60 Hz mains frequency). This is the voltage we measure."

Engineer leads effort to develop computer systems that can see better than humans

"Deep learning" is the task at hand for Vijaykrishnan Narayanan and his multidisciplinary team of researchers who are developing computerized vision systems that can match—and even surpass—the capabilities of human vision. Narayanan, professor of computer science and engineering and electrical engineering, and his team received a $10 million Expeditions in Computing award from the National Science Foundation (NSF) last fall to enhance the ability of computers to not only record imagery, but to actually understand what they are seeing—a concept that Narayanan calls "deep learning."

For secure software: X-rays instead of passport control

Trust is good, control is better. This also applies to the security of computer programs. Instead of trusting "identification documents" in the form of certificates, JOANA, the new software analysis tool, examines the source text (code) of a program. In this way, it detects leaks, via which secret information may get out or strangers may enter the system from outside. At the same time, JOANA reduces the number of false alarms to a minimum. The analysis tool developed by Karlsruhe Institute of Technology (KIT) has already proved to work successfully in realistic test scenarios. In a next step, an industrial case study is planned.

Smartphone-loss anxiety disorder

The smart phone has changed our behavior, sometimes for the better as we are now able to connect and engage with many more people than ever before, sometimes for the worse in that we may have become over-reliant on the connectivity with the outside world that these devices afford us. Either way, there is no going back for the majority of users who can almost instantaneously connect with hundreds if not thousands of people through the various social media and other applications available on such devices and not least through the humble phone call.

We need new laws to govern cyberwarfare

President Bush is reported to have said: "When I take action, I'm not going to fire a US$2m missile at a US$10 empty tent and hit a camel in the butt. It's going to be decisive." As the quote suggests, when it comes to national defence, enemies are unlikely to be deterred by an army of three, a leaky canoe and a fleet of second-hand microlights. In times of war we usually expect a powerful, graphic display of military might.

Researchers use expanding gels to mimic creation of folds in mammalian brain

(Medical Xpress)—A team of researchers with members from facilities in Finland, the U.S., and the U.K. has found a way to mimic the process that leads to folds in mammalian brains. In their paper published in Proceedings of the National Academy of Sciences, the team describes how they developed computer models to explain the development of folds in the cerebral cortex and then used what they'd learned to mimic the process using expanding gels.

Children with autism have extra synapses in brain

Children and adolescents with autism have a surplus of synapses in the brain, and this excess is due to a slowdown in a normal brain "pruning" process during development, according to a study by neuroscientists at Columbia University Medical Center (CUMC). Because synapses are the points where neurons connect and communicate with each other, the excessive synapses may have profound effects on how the brain functions. The study was published in the August 21 online issue of the journal Neuron.

Biologists reprogram skin cells to mimic rare disease

Johns Hopkins stem cell biologists have found a way to reprogram a patient's skin cells into cells that mimic and display many biological features of a rare genetic disorder called familial dysautonomia. The process requires growing the skin cells in a bath of proteins and chemical additives while turning on a gene to produce neural crest cells, which give rise to several adult cell types. The researchers say their work substantially expedites the creation of neural crest cells from any patient with a neural crest-related disorder, a tool that lets physicians and scientists study each patient's disorder at the cellular level.

The finding revealed a promising new way to customise a potentially preventive drug for atherosclerosis.

Learning to play the piano? Sleep on it!

According to researchers at the University of Montreal, the regions of the brain below the cortex play an important role as we train our bodies' movements and, critically, they interact more effectively after a night of sleep. While researchers knew that sleep helped us the learn sequences of movements (motor learning), it was not known why. "The subcortical regions are important in information consolidation, especially information linked to a motor memory trace. When consolidation level is measured after a period of sleep, the brain network of these areas functions with greater synchrony, that is, we observe that communication between the various regions of this network is better optimized. The opposite is true when there has been no period of sleep," said Karen Debas, neuropsychologist at the University of Montreal and leader author of the study. A network refers to multiple brain areas that are activated simultaneously.

Researchers examine impact of race and ethnicity in motor complete spinal cord injury

Researchers have published a study examining racial and ethnic influences in the outcomes of patients with motor complete spinal cord injury (SCI). The article, "Racial and ethnic disparities in functioning at discharge and follow-up among patients with motor complete SCI," was published online ahead of print on August 2 by the Archives of Physical Medicine & Rehabilitation. Findings included small but significant differences in self-care and mobility at discharge; no differences were apparent at 1-year followup. Authors are Denise Fyffe, PhD, and Amanda Botticello, PhD, MPH, of Kessler Foundation, Steven Kirshblum, MD, of Kessler Institute for Rehabilitation, Anne Deutsch, RN, PhD, CRRN, of Rehabilitation Institute of Chicago and RTI International, and Kenneth Ottenbacher, PhD, OTR, of the University of Texas Medical Branch.

Coronary calcium predicts heart disease risk in patients with chronic kidney disease

Calcium buildup in the coronary arteries may be a better indicator of kidney disease patients' risk of heart disease than traditional risk factors used in the general population, according to a study appearing in an upcoming issue of the Journal of the American Society of Nephrology (JASN). The findings provide valuable new information that could help safeguard the heart health of patients with kidney disease.

Vision loss adversely affects daily function which can increase risk for death

Vision loss can adversely affect the ability of older adults to perform instrumental activities of daily living (IADL), such as using the telephone, shopping and doing housework, which are all measures of an individual's ability to live independently, and that subsequently increases the risk for death.

New process helps overcome obstacles to produce renewable fuels and chemicals

(Phys.org) —There's an old saying in the biofuels industry: "You can make anything from lignin except money." But now, a new study may pave the way to challenging that adage. The study from the Energy Department's National Renewable Energy Laboratory (NREL) demonstrates a concept that provides opportunities for the successful conversion of lignin into a variety of renewable fuels, chemicals, and materials for a sustainable energy economy.

Alternate mechanism of species formation picks up support, thanks to a South American ant

A newly-discovered species of ant supports a controversial theory of species formation. The ant, known to live only under a single eucalyptus tree on the São Paulo State University campus in Brazil, branched off from its original species while living in the same colony, something thought rare in current models of evolutionary development.

Some anti-inflammatory drugs affect more than their targets

Researchers have discovered that three commonly used nonsteroidal anti-inflammatory drugs, or NSAIDs, alter the activity of enzymes within cell membranes. Their finding suggests that, if taken at higher-than-approved doses and/or for long periods of time, these prescription-level NSAIDs and other drugs that affect the membrane may produce wide-ranging and unwanted side effects.

Salmon forced to 'sprint' less likely to survive migration

Sockeye salmon that sprint to spawning grounds through fast-moving waters may be at risk, suggests new research by University of British Columbia scientists.

Canola flowers faster with heat genes

(Phys.org) —A problem that has puzzled canola breeders for years has been solved by researchers from The University of Western Australia - and the results could provide a vital breakthrough in understanding the impact of increasing global temperatures on crop flowering.

Of bees, mites, and viruses

Honeybee colonies are dying at alarming rates worldwide. A variety of factors have been proposed to explain their decline, but the exact cause—and how bees can be saved—remains unclear. An article published on August 21st in PLOS Pathogens examines the viral landscape in honeybee colonies in New Zealand after the recent arrival of the parasitic Varroa destructor mite.

From dandruff to deep sea vents, an ecologically hyper-diverse fungus
