When investigating a murder, every clue helps. New research from North Carolina State University sheds light on how – and whether – blow flies survive when buried underground during their development. It's an advance that will help forensic investigators understand how long a body may have been left above ground before being buried – or possibly whether remains were moved from one grave to another.

LOMA LINDA, Calif. — New research shows that following a vegetarian diet and exercising at least three times a week significantly reduced the risk of diabetes in African Americans, who are twice as likely to be diagnosed with diabetes when compared to non-Hispanic whites.

CLEMSON, S.C. — Your ability to recognize emotional content in faces and texts is linked to your blood pressure, according to a Clemson University researcher.

A recently published study by Clemson University psychology professor James A. McCubbin and colleagues has shown that people with higher blood pressure have reduced ability to recognize angry, fearful, sad and happy faces and text passages.

Hybrid cars, powered by a mixture of gas and electricity, have become a practical way to "go green" on the roads. Now researchers at Tel Aviv University are applying the term "hybrid" to power plants as well.

WASHINGTON, Nov. 2—In the emerging field of tissue engineering, scientists encourage cells to grow on carefully designed support scaffolds. The ultimate goal is to create living structures that might one day be used to replace lost or damaged tissue, but the manufacture of appropriately detailed scaffolds presents a significant challenge that has kept most tissue engineering applications confined to the research lab.

Professional safecrackers use a stethoscope to find the correct combination by listening to the clicks of the lock. Researchers at the Ruhr-University Bochum have now demonstrated how to bypass the security mechanisms of a widely used contactless smartcard in a similar way. Employing so-called "Side-Channel Analysis" the researchers of the Chair for Embedded Security (Prof. Dr.-Ing. Christof Paar) can break the cryptography of millions of cards that are used all around the world.

Santa Barbara, Calif. –– A discovery by physicists at UC Santa Barbara may earn silicon carbide –– a semiconductor commonly used by the electronics industry –– a role at the center of a new generation of information technologies designed to exploit quantum physics for tasks such as ultrafast computing and nanoscale sensing.

The research team discovered that silicon carbide contains crystal imperfections that can be controlled at a quantum mechanical level. The finding is published this week in the journal Nature.

The world may seem painted with endless color, but physiologically the human eye sees only three bands of light — red, green, and blue. Now a Tel Aviv University-developed technology is using colors invisible to the naked eye to analyze the world we live in. With the ability to detect more than 1,000 colors, the "hyperspectral" (HSR) camera, like Mr. Spock's sci-fi "Tricorder," is being used to "diagnose" contaminants and other environmental hazards in real time.

Solar power may be on the rise, but solar cells are only as efficient as the amount of sunlight they collect. Under the direction of a new professor at Northwestern University's McCormick School of Engineering and Applied Science, researchers have developed a new material that absorbs a wide range of wavelengths and could lead to more efficient and less expensive solar technology.

As soon as DNA is mentioned, we automatically think of biology and living beings. It is the DNA molecule found inside each and every cell that holds the encoded blueprints for humans, animals or plants. But factories too have a master plan of this kind. All modern manufacturing facilities resemble living organisms in their complex structure. And, just as in biology, all their constituent parts are linked to one another and have to be painstakingly coordinated.

When fat, sugar and gluten come out of salad dressings, sauces, cookies, beverages, and other foods with the new genre of package labels shouting what's not there, what goes into "light" or "-free" versions of products to make them taste like the original version? The answers appear in the cover story in the current edition of Chemical & Engineering News, ACS' weekly newsmagazine.

A flying robot as small as a dinner plate that can zoom to hard-to-reach places and a fleet of eco-friendly robotic farm-hands are just two of the exciting projects the robotics team at the Queensland University of Technology (QUT), based in Brisbane, Australia, is working on.

The pint-sized propellor-powered robots can be packed away into a suitcase. They have multiple cameras which enable them to 'see' the world around them as they navigate their way through buildings, carrying out tasks like deliveries or inspections.

Piroska Östlin of the WHO, Copenhagen, Denmark and colleagues argue in this week's PLoS Medicine that a paradigm shift is needed to keep the focus on health equity within the social determinants of health research agenda. The authors recommend four priority areas for future research on health equity, and suggest possible steps for advancing such an agenda, such as creating a critical mass of researchers and refining norms and standards for the monitoring and assessment of health inequalities.

Cambridge, Mass. -- Americans spend upwards of $40 billion a year on dieting advice and self-help books, but the first step in any healthy eating strategy is basic awareness -- what's on the plate.

If keeping a food diary seems like too much effort, despair not: computer scientists at the Harvard School of Engineering and Applied Sciences (SEAS) have devised a tool that lets you snap a photo of your meal and let the crowd do the rest.

Drying of northern wetlands has led to much more severe peatland wildfires and nine times as much carbon released into the atmosphere, according to new research led by a University of Guelph professor.

The study, published today in Nature Communications, is the first to investigate the effect of drainage on carbon accumulation in northern peatlands and the vulnerability of that carbon to burning.
