NYU study: Blood from periodontal disease can be used to screen for diabetes

Oral blood samples drawn from deep pockets of periodontal inflammation can be used to measure hemoglobin A1c, an important gauge of a patient's diabetes status, an NYU nursing-dental research team has found. Hemoglobin A1c blood glucose measures from oral blood...

UCLA engineers create tandem polymer solar cells that set record for energy-conversion

In the effort to convert sunlight into electricity, photovoltaic solar cells that use conductive organic polymers for light absorption and conversion have shown great potential. Organic polymers can be produced...

In older adults, fluctuating sense of control linked to cognitive ability

Everyone has moments when they feel more in control of their lives than at other times. New research from North Carolina State University shows that this sense of control fluctuates...

New cases of rare genetic disorder identified

Scientists at the University of Liverpool, working with international partners, have shown a rare genetic disease, that causes crippling osteoarthritis in the spine and major joints, is far more prevalent...

Motivation to exercise affects behavior

For many people, the motivation to exercise fluctuates from week to week, and these fluctuations predict whether they will be physically active, according to researchers at Penn State. In an...

Researchers discover molecular secrets of ancient Chinese herbal remedy

For roughly two thousand years, Chinese herbalists have treated Malaria using a root extract, commonly known as Chang Shan, from a type of hydrangea that grows in Tibet and Nepal....

A mitosis mystery solved: How chromosomes align perfectly in a dividing cell

To solve a mystery, sometimes a great detective need only study the clues in front of him. Like Agatha Christie's Hercule Poirot and Arthur Conan Doyle's Sherlock Holmes, Tomomi Kiyomitsu...

Arthritic knees, but not hips, have robust repair response

Researchers at Duke University Medical Center used new tools they developed to analyze knees and hips and discovered that osteoarthritic knee joints are in a constant state of repair, while...

Hovering not hard if you're top-heavy, NYU researchers find

Top-heavy structures are more likely to maintain their balance while hovering in the air than are those that bear a lower center of gravity, researchers at New York University's Courant...

Putting the squeeze on planets outside our solar system

Just as graphite can transform into diamond under high pressure, liquid magmas may similarly undergo major transformations at the pressures and temperatures that exist deep inside Earth-like planets.

Researchers develop new method for creating tissue engineering scaffolds

Researchers at Northwestern University have developed a new method for creating scaffolds for tissue engineering applications, providing an alternative that is more flexible and less time-intensive than current technology.

Big fish reveal shelter secrets on reefcam

When it comes to choosing a place to hang out, big reef fish like coral trout, snappers and sweetlips have strong architectural preferences.

Indiana University scientist works to detach protein that HIV uses as protective shield

One of the frustrations for scientists working on HIV/AIDS treatments has been the human immunodeficiency virus' ability to evade the body's immune system. Now an Indiana University researcher has discovered...

Children at risk for ingestion of PAHs from pavement sealant, study finds

Children living near coal-tar-sealed pavement are likely to receive a far higher dose of carcinogenic polycyclic aromatic hydrocarbons (PAHs) from incidental ingestion of house dust than do children living near...

New HIV-vaccine tested on people

Scientists from the Antwerp Institute of Tropical Medicine, Antwerp University Hospital and Antwerp University have tested a new 'therapeutic vaccine' against HIV on volunteers. The participants were so to say...

Starve a virus, feed a cure?

A protein that protects some of our immune cells from the most common and virulent form of HIV works by starving the virus of the molecular building blocks that it...

Researchers develop method to examine batteries -- from the inside

There is an ever-increasing need for advanced batteries for portable electronics, such as phones, cameras, and music players, but also to power electric vehicles and to facilitate the distribution and...

Human cognitive performance suffers following natural disasters, HF/E researchers find

Not surprisingly, victims of a natural disaster can experience stress and anxiety, but a new study indicates that it might also cause them to make more errors -- some serious-...

3-D laser map shows earthquake before and after

Geologists have a new tool to study how earthquakes change the landscape down to a few inches, and it's giving them insight into how earthquake faults behave. In the Feb....

The power of estrogen -- male snakes attract other males

A new study has shown that boosting the estrogen levels of male garter snakes causes them to secrete the same pheromones that females use to attract suitors, and turned the...

Grass to gas: UGA researchers' genome map speeds biofuel development

Researchers at the University of Georgia have taken a major step in the ongoing effort to find sources of cleaner, renewable energy by mapping the genomes of two originator cells...

Domestic consumption main contributor to Africa's growing E-waste
