Make a New Year's resolution to manage your diabetes

Posted: 31 Dec 2014 08:37 AM PST

Early detection and treatment can decrease the risk of developing complications from diabetes. Certified diabetes educators report that the new year is a good time to see a doctor if you think you have diabetes.

Dawn spacecraft begins approach to dwarf planet Ceres

Posted: 31 Dec 2014 08:19 AM PST

NASA's Dawn spacecraft has entered an approach phase in which it will continue to close in on Ceres, a Texas-sized dwarf planet never before visited by a spacecraft. Dawn launched in 2007 and is scheduled to enter Ceres orbit in March 2015.

Discovery of mutated gene in dogs could help treat blindness

Posted: 31 Dec 2014 06:57 AM PST

A MERTK gene defect responsible for a recently identified form of progressive retinal atrophy in Swedish vallhund dogs has been found by an international team of scientists. This discovery opens the door to the development of therapies for diseases that cause blindness both in dogs and humans.

Significant link between daily physical activity, vascular health

Posted: 31 Dec 2014 06:56 AM PST

As millions of Americans resolve to live healthier lives in 2015, research shows just how important diligent daily physical activity is. The researchers found that reducing daily physical activity for even a few days leads to decreases in the function of the inner lining of blood vessels in the legs of young, healthy subjects causing vascular dysfunction that can have prolonged effects.

Parental history of suicide attempt associated with increased risk in kids

Posted: 30 Dec 2014 06:10 PM PST

A suicide attempt by a parent increased the odds nearly five-fold that a child would attempt suicide, according to a report. Other studies have established that suicidal behavior can run in families but few studies have looked at the pathways by which suicidal behavior is transmitted in families.

Molecules seen binding to HIV-1's protective capsule, blocking infection

Posted: 30 Dec 2014 01:08 PM PST

New research shows an HIV-1 inhibitor and a host protein binding to HIV-1's protective capsule, preventing it from disassembling. Viral genetic information is kept inside. Researchers believe the process can be targeted for therapeutic purposes in HIV-1 infections.

Cancer treatment potential discovered in gene repair mechanism

Posted: 30 Dec 2014 11:52 AM PST

A two-pronged therapeutic approach has been discovered that shows great potential for weakening and then defeating cancer cells. The research team's complex mix of genetic and biochemical experiments unearthed a way to increase the presence of a tumor-suppressing protein which, in turn, gives it the strength to direct cancer cells toward a path that leads to their destruction.

Malaria combination drug therapy for children

Posted: 30 Dec 2014 11:52 AM PST

A drug combination of artemisinin-naphthoquine should be considered for the treatment of children with uncomplicated malaria in settings where multiple parasite species cause malaria according to researchers.

Gift-wrapped gas molecules

Posted: 30 Dec 2014 08:18 AM PST

A group of scientists has worked out how to stably gift-wrap a chemical gas known as nitric oxide within metal-organic frameworks. Such an encapsulated chemical may allow doctors to administer nitric oxide in a more highly controlled way to patients, suggesting new approaches for treating dangerous infections and heart conditions with the biologically-active substance.

New treatment strategy allows lower doses of toxic tuberculosis drug without compromising potency

Posted: 30 Dec 2014 07:20 AM PST

While an effective treatment is available for combating multidrug-resistant tuberculosis, it carries serious side effects for patients. New research shows that lower doses of the toxic drug bedaquiline — given together with verapamil, a medication that's used to treat various heart conditions — can lead to the same antibacterial effects as higher toxic doses of bedaquiline.

Neutrinos can deliver not only full-on hits but also 'glancing blows'

Posted: 30 Dec 2014 07:19 AM PST

In what they call a 'weird little corner' of the already weird world of neutrinos, physicists have found evidence that these tiny particles might be involved in a surprising reaction. Neutrinos are famous for almost never interacting. As an example, ten trillion neutrinos pass through your hand every second, and fewer than one actually interacts with any of the atoms that make up your hand. However, when neutrinos do interact with another particle, it happens at very close distances and involves a high-momentum transfer.

Simulation of universe with realistic galaxies

Posted: 30 Dec 2014 07:19 AM PST

An international team of astronomers has developed a simulation of the universe in which realistic galaxies are created; their mass, size and age are similar to those of observed galaxies. Their similarity is caused by the simulation of strong galactic winds -- gas winds that are blown from galaxies.
