Licorice is a hot trend in hot flashes, but could interact with medications

Dom, 08/20/2017 - 22:00
Licorice roots have a flavorful history, having been used in ancient Egyptian teas and in traditional Chinese medicines, all the way to today as a flavoring agent and candy. And some women now take licorice extracts as supplements to treat menopausal symptoms. But scientists caution that licorice could pose a health risk by interacting with medications. The researchers are presenting their results today at the 254th National Meeting & Exposition of the American Chemical Society.

Racial stereotypes influence perception of NFL quarterbacks

Dom, 08/20/2017 - 22:00
Racial stereotypes affect the public's perception of NFL quarterbacks and may, in some cases, become a self-fulfilling prophecy for black athletes, new University of Colorado Boulder research shows.

Behavior theory may offer key to ensuring infants are put to sleep safely

Dom, 08/20/2017 - 22:00
It is still common for infants to be placed in unsafe sleeping positions by their caregivers, report researchers from Yale and Boston University (BU). Fewer than half of infants are always placed on their backs for sleep, the recommended safe sleep position.

Comparison of screening recommendations indicates annual mammography

Dom, 08/20/2017 - 22:00
When to initiate screening for breast cancer, how often to screen, and how long to screen are questions that continue to spark emotional debates.

Sedentary behavior increases risk of death for frail, inactive adults

Dom, 08/20/2017 - 22:00
Sedentary time, for example, time spent sitting, increases the risk of death for middle-aged and older people who are frail and inactive, but does not appear to increase the risk for non-frail people who are inactive, according to a new study published in CMAJ.

Key protein to regulate synapse formation

Sáb, 08/19/2017 - 22:00
Korean researchers have identified the control mechanism of synapse formation using a protein crystallography method. It is expected to be used in the study of brain diseases caused by dysfunction of synapses and to develop therapeutic drugs.

3-D particle tracking? There's an app for that

Sáb, 08/19/2017 - 22:00
Smartphones put state-of-the-art 3-D particle tracking in the hands of the masses.

People who hear voices can detect hidden speech in unusual sounds

Sáb, 08/19/2017 - 22:00
People who hear voices that other people can't hear may use unusual skills when their brains process new sounds, according to research led by Durham University and University College London (UCL).

Sugars in human mother's milk are new class of antibacterial agents

Sáb, 08/19/2017 - 22:00
A new study has found that sugars in mother's' milk do not just provide nutrition for babies but also help protect them from bacterial infections, making them a new class of antimicrobial agent.

Silk could improve sensitivity, flexibility of wearable body sensors

Sáb, 08/19/2017 - 22:00
From smart socks to workout clothes that measure exertion, wearable body sensors are becoming the latest 'must-have' technology. Now scientists report they are on the cusp of using silk, one of the world's most coveted fabrics, to develop a more sensitive and flexible generation of these multi-purpose devices that monitor a slew of body functions. The researchers are presenting their results at the 254th National Meeting & Exposition of the American Chemical Society.

Mussel-inspired glue could one day make fetal surgery safer

Sáb, 08/19/2017 - 22:00
Whether to perform surgery on a fetus is a heart-wrenching decision. This type of surgery involves penetrating the delicate amniotic sac, increasing health risks to the fetus. Now researchers report the development of a glue, inspired by the tenacious grip of mussels on slippery rocks, that could one day help save the lives of the youngest patients. The researchers present their findings today at the 254th National Meeting & Exposition of the American Chemical Society.

No guts no glory: Harvesting the microbiome of athletes

Sáb, 08/19/2017 - 22:00
Scientists have tapped into the microbiome of elite runners and rowers, and have identified particular bacteria that may aid athletic performance. The goal is to develop probiotic supplements that may help athletes -- and even amateur fitness enthusiasts -- recover from a tough workout or more efficiently convert nutrients to energy. The researchers will present their work today at the 254th National Meeting & Exposition of the American Chemical Society.

Sugars in some breast milk could help protect babies from group B strep

Sáb, 08/19/2017 - 22:00
Group B strep bacteria remain the leading cause of severe infections in newborns worldwide. Now researchers have found that although the pathogen can be transmitted to infants through breastfeeding, some mothers produce protective sugars in their milk that could help prevent infection and fight biofilm formation -- the first example of carbohydrates in human milk having this function. The researchers are presenting their results at the 254th National Meeting & Exposition of the American Chemical Society.

Testing TVs and tablets for 'green' screens

Sáb, 08/19/2017 - 22:00
Today, researchers report preliminary results suggesting that under simulated landfill conditions, quantum dots can leach out of TVs and tablets. But because this happens in such tiny amounts, the team says that in the grand scheme of things, it might make sense to use the more toxic quantum dots that are made with a more eco-friendly process. The researchers are presenting their results at the 254th National Meeting & Exposition of the American Chemical Society.

Energized fabrics could keep soldiers warm and battle-ready in frigid climates

Sáb, 08/19/2017 - 22:00
Soldiering in arctic conditions is tough. Protective clothing can be heavy and can cause overheating and sweating, while hands and feet can grow numb. To keep military personnel more comfortable, scientists are trying to create high-tech fabrics that heat up when powered and that capture sweat. These fabrics could conceivably be used in future consumer clothing. The researchers will present their results today at the 254th National Meeting & Exposition of the American Chemical Society.

Wood frogs research clarifies risks posed to animals by warming climate

Vie, 08/18/2017 - 22:00
As conditions warm, fish and wildlife living at the southern edge of their species' ranges are most at risk, according to Penn State researchers who led a major collaborative study of how wood frogs are being affected by climate change.

Few women with history of breast cancer and ovarian cancer take a recommended genetic test

Jue, 08/17/2017 - 22:00
More than 80 percent of women living with a history of breast or ovarian cancer at high-risk of having a gene mutation have never taken the test that can detect it.

Yemen's Saudi-led coalition is responsible for the 'worst cholera outbreak in the world'

Jue, 08/17/2017 - 22:00
The cholera outbreak in Yemen is overwhelmingly affecting rebel-controlled areas due to Saudi-led airstrikes and blockades, according to a letter by researchers from Queen Mary University of London, published in The Lancet Global Health.

Seeking the secret ingredient in the original smallpox vaccine

Jue, 08/17/2017 - 22:00
Thanks to a secret vaccine ingredient as well as a net of worldwide researchers and successful vaccination campaigns, smallpox was finally eradicated in 1977. A new study entitled 'Revisiting Jenner's mysteries, the role of the Beaugency lymph in the evolutionary path of ancient smallpox vaccines' and published in The Lancet Infectious Diseases, provides an in-depth investigation of the mysteries associated with the development of smallpox vaccine and is a rich and interesting account of how the vaccine lymph was spread worldwide.
