UAlberta researchers are taking a closer look at how two metabolic pathways interact to increase the lifespan of cells with mitochondrial defects. Magnus Friis is the lead author of the study, which was published online on April 10 and will be published in the April 24 issue of Cell Reports.

A new paper from the Swansea University, College of Engineering team working on the BLOODHOUND SSC (Supersonic car) project has been published on the aerodynamic characteristics of travelling at 1,000mph. Simulations have looked at how the car will cope with the supersonic rolling ground, rotating wheels and resulting shock waves in close proximity to the test surface at the record attempt site in Hakskeen Pan, South Africa. Where, in 2015, it will make high speed test runs of up to 800mph, with the full 1,000mph attempt scheduled for 2016.
Scratches in the car finish or cracks in polymer material: Self-healing materials can repair themselves by restoring their initial molecular structure after the damage. Scientists of the Karlsruhe Institute of Technology and Evonik Industries have developed a chemical crosslinking reaction that ensures good short-term healing properties of the material under mild heating. The research results have now been published in the Advanced Materials journal. DOI:10.1002/adma.201306258
Researchers are programming robots to communicate with people using human-like body language and cues, an important step toward bringing robots into homes.
Researchers at the University of British Columbia enlisted the help of a human-friendly robot named Charlie to study the simple task of handing an object to a person. Past research has shown that people have difficulty figuring out when to reach out and take an object from a robot because robots fail to provide appropriate nonverbal cues.
In a feat that may provide a promising array of applications, from energy efficiency to telecommunications to enhanced imaging, researchers at UC Santa Barbara have created a compound semiconductor of nearly perfect quality with embedded nanostructures containing ordered lines of atoms that can manipulate light energy in the mid-infrared range. More efficient solar cells, less risky and higher resolution biological imaging, and the ability to transmit massive amounts of data at higher speeds are only a few applications that this unique semiconductor will be able to support.
Academics at the University of Sheffield have dispelled a long-held theory that the Titanic was unlucky for sailing in a year with an exceptional number of icebergs and say the risk of icebergs is actually higher now.
Previously it had been suggested that the seas which sank the famous cruise ship – which set off on its maiden voyage 102 years ago today (Thursday 10 April 2014) – had an exceptional number of icebergs caused by lunar or solar effects.
But academics at the University have shown the ship wasn't as unlucky as previously thought.
Porous silicon manufactured in a bottom up procedure using solar energy can be used to generate hydrogen from water, according to a team of Penn State mechanical engineers, who also see applications for batteries, biosensors and optical electronics as outlets for this new material.
The surface area of this porous silicon is high," said Donghai Wang, assistant professor of mechanical engineering. "It is widely used and has a lot of applications."
The standard method for manufacturing porous silicon is a subtraction method, similar to making a sculpture.
Providence, RI---Your financial advisor calls you up to suggest a newinvestment scheme. Drawing on 20 years of data, he has set hiscomputer to work on this question: If you had invested according tothis scheme in the past, which portfolio would have been the best?His computer assembled thousands of such simulated portfolios andcalculated for each one an industry-standard measure of return onrisk. Out of this gargantuan calculation, your advisor has chosen theoptimal portfolio.
An international team of scientists has reported the first experimental observation of the quantum critical point (QCP) in the extensively studied "unconventional superconductor" TiSe2, finding that it does not reside as predicted within the superconducting dome of the phase diagram, but rather at a full GPa higher in pressure.
The team has so far identified 14 vulnerable HTML5-based apps from three types of mobile systems, including Android, iOS and Blackberry. Developers of those vulnerable apps have been informed and in an effort to give them time to fix the problem, researchers have decided not to disclose the names of the vulnerable apps.
Growing agave and other carefully chosen plants amid photovoltaic panels could allow solar farms not only to collect sunlight for electricity but also to produce crops for biofuels, according to new computer models by Stanford scientists.
Stanford University scientists have found a new, highly efficient way to produce liquid ethanol from carbon monoxide gas. This promising discovery could provide an eco-friendly alternative to conventional ethanol production from corn and other crops, say the scientists. Their results are published in the April 9 advanced online edition of the journal Nature.
OAK RIDGE, Tenn., April 9, 2014 – People who pack their cars and drive like Clark Griswold in National Lampoon's "Vacation" pay a steep penalty when it comes to fuel economy, according to a report by the Department of Energy's Oak Ridge National Laboratory.
Scientists in Singapore develop novel ultra-fast electrical circuits using light-generated tunneling

The expansion of health insurance accomplished under the Affordable Care Act may alter costs for several major types of liability insurance, although any such changes are likely to be modest, according to a new RAND Corporation report.
Automobile, workers' compensation and general business liability insurance costs may fall under the Affordable Care Act, while costs for medical malpractice coverage could be higher, according to the study.
