Enzyme triggers cell death in heart attack
Adding a third anti-cancer agent to a current drug cocktail appears to have contributed to dramatic improvement in three infants with the most severe form of Pompe disease -- a rare, often-fatal genetic disorder characterized by low or no production of an enzyme crucial to...

More than just 'zoning out': Exploring the cognitive processes behind mind wandering
A new study shows that CaM kinase II enzyme activity triggers heart cell death by making the cells' energy-producing mitochondria leaky. Inhibiting the enzyme in mitochondria protected mice from heart cell death during heart attack and other forms of heart stress. The findings could lead to better therapies for common forms of heart...

New studies could result in better treatments for epilepsy, behavioral disorders
It happens innocently enough: One minute you're working on a report and the next minute you're thinking about how you need to do laundry. Mind wandering is frequent and common. And while it can be counterproductive, research suggests that mind wandering isn't necessarily a bad thing. New research explores mind wandering in various contexts, examining how it relates to cognitive processes involved...

Regular Aspirin Use May Reduce Ovarian Cancer Risk
Early results of a Phase II intra-arterial stem cell trial for ischemic stroke showed no adverse events associated with the first 10 patients, allowing investigators to expand the study to a targeted total of 100 patients.
Massive diamond planet discovered by astronomers
Regularly taking certain pain relievers may reduce women's risk of deadly ovarian cancer, a new study from Denmark suggests.
Transplanted Purcell Mountain caribou fail to survive
New research led by Yale University scientists suggests that a rocky planet twice Earth's size is composed partially of diamond.
Green Blog: Panda Cub Died of Lung and Liver Damage
An expensive plan to relocate mountain caribou from northern B.C. to the Kootenays, has failed after 15 of the 19 transplanted caribou died from accidents, predators or undetermined causes.

The Smithsonian National Zoo discloses the results of a final necropsy.
Samsung Intros Galaxy S III Mini with Smaller Screen, Lower Specs
NEW YORK — Prominent climate scientist James Hansen has been warning that humans have brought the planet to a tipping point, after which changes, such as melting ice, can pick up momentum with potentially devastating effects.

A Handheld Projector You Might Actually Want
Adding even more size diversity to its array of Android devices, mobile king Samsung Electronics on Thursday unveiled its Galaxy S III mini, a scaled-down version of its flagship phone, targeted at European markets.
Instead of 4.8 inches, its Super AMOLED touchscreen is just 4 inches, the same size as Apple's iPhone 5. The iPhone is the most popular single device in the world, while Samsung is...
Despite slow start, ebooks gain ground in Europe
With built-in Roku, it's like a portable internet TV.
Here’s something you probably didn’t know you wanted. 3M has come up with a handheld projector--or “picoprojector”--with a Roku Streaming Stick built in. That means that the $300 device can function as something of a portable TV, with access to Netflix, Amazon Instant, Hulu Plus, HBO Go, and the like....
Developmental biologist proposes new theory of early animal evolution, challenges basic assumptions
Electronic books, which have sparked excited chatter for several years in the publishing world, are now gaining momentum among European readers, despite a late start compared to the US, industry insiders say.
Earth sunblock only needed if planet warms easily
A New York Medical College developmental biologist whose life's work has supported the theory of evolution has developed a concept that dramatically alters one of its basic assumptions—that survival is based on a change's functional advantage if it is to persist. Stuart A. Newman, Ph.D., professor of cell biology and anatomy, offers an alternative model in proposing that the origination of the...
Fly eye mystery: Research provides insight into why flies have fastest vision in animal kingdom
(Phys.org)—An increasing number of scientists are studying ways to temporarily reduce the amount of sunlight reaching the earth to potentially stave off some of the worst effects of climate change. Because these sunlight reduction methods would only temporarily reduce temperatures, do nothing for the health of the oceans and affect different regions unevenly, researchers do not see it as a...
Focus on space debris: Envisat
Fly eyes have the fastest visual responses in the animal kingdom, but how they achieve this has long been an enigma. A new study shows that their rapid vision may be a result of their photoreceptors - specialised cells found in the retina - physically contracting in response to light. The mechanical force then generates electrical responses that are sent to the brain much faster than, for example,...
Friends vie for bragging rights online at TopThat
(Phys.org)—Space debris came into focus last week at the International Astronautical Congress in Naples, Italy. Envisat, ESA's largest Earth observation satellite, ended its mission last spring and was a subject of major interest in the Space Debris and Legal session.
Half-century-long quest to observe chemical reactions in quantum realm achieved
Brandon Caruana thinks friends are ready to swap online social network niceties for trash talk and competition in a virtual arena that challenges people to "TopThat."
Moroccan desert meteorite delivers Martian secrets
At very low temperatures, close to absolute zero, chemical reactions may proceed at a much higher rate than classical chemistry says they should – because in this extreme chill, quantum effects enter the picture. A Weizmann Institute team has now confirmed this experimentally; their results would not only provide insight into processes in the intriguing quantum world in which particles act as...
New web-based model for sharing research datasets could have huge benefits
A meteorite that landed in the Moroccan desert 14 months ago is providing more information about Mars, the planet where it originated. University of Alberta researcher Chris Herd helped in the study of the Tissint meteorite, in which traces of Mars' unique atmosphere are trapped.
Researchers ID unique geological 'sombrero' uplift in South America
A group of researchers have proposed creating a new web-based data network to help researchers and policymakers worldwide turn existing knowledge into real-world applications and technologies and improve science and innovation policy.
Researchers work across fields to uncover information about hadrosaur teeth
(Phys.org)—Scientists at Scripps Institution of Oceanography at UC San Diego have used 20 years of satellite data to reveal a geological oddity unlike any seen on Earth.
Scientists focus on quorum sensing to better understand bacteria
(Phys.org)—An unusual collaboration between researchers in two disparate fields resulted in a new discovery about the teeth of 65-million-year-old dinosaurs.
Unusual genetic structure confers major disease resistance trait in soybean
The relatively new field in microbiology that focuses on quorum sensing has been making strides in understanding how bacteria communicate and cooperate. Quorum sensing describes the bacterial communication between cells that allows them to recognize and react to the size of their surrounding cell population. While a cell's output of extracellular products, or "public goods," is dependent on the...
Scientists have identified three neighboring genes that make soybeans resistant to the most damaging disease of soybean. The genes exist side-by-side on a stretch of chromosome, but only give resistance when that stretch is duplicated several times in the plant.
