MIT research: Delivering RNA with tiny sponge-like spheres
A new RNA interference method holds promise for treating cancer and other diseases.

Mass. General researchers isolate egg-producing stem cells from adult human ovaries
For the first time, Massachusetts General Hospital researchers have isolated egg-producing stem cells from the ovaries of reproductive age women and shown these cells can produce what appear to be normal egg cells or oocytes.

Elusive platelet count and limb development gene discovered
This release outlines the identification of an elusive gene responsible for Thrombocytopenia with Absent Radii, a rare inherited blood and skeletal disorder.

New insights into understanding brain performance
People who take Ritalin are far more aware of their mistakes, a University of Melbourne study has found.

New drug improves glucose control without increasing risk of hypoglycemia in patients with Type 2 diabetes
TAK-875, a new treatment for Type 2 diabetes, improves glycemic (blood sugar) control and is equally as effective as the sulphonylurea glimepiride (a common drug treatment) but has a significantly lower risk of hypoglycemia (low blood sugar) and few side effects, according to the results of a Phase 2 randomized trial published online first in the Lancet.

Volcanoes deliver 2 flavors of water
By analyzing submarine volcanic glass from the Manus Basin, scientists found unexpected changes in hydrogen and boron isotopes from the deep mantle.

Ancient Arabic writings help scientists piece together past climate
Ancient manuscripts written by Arabic scholars can provide valuable meteorological information to help modern scientists reconstruct the climate of the past, a new study has revealed.

Some bacteria attack using spring-loaded poison daggers
Bacteria have evolved different systems for secreting proteins. One, called a type VI secretion system, is found in about a quarter of all bacteria with two membranes.

Scientists score 1 more victory over uncertainty in quantum physics measurements
Uncertainty affects the accuracy with which measurements can be made in quantum physics.

Call for tough new targets on European Union energy reduction
Energy efficiency experts at the University of East Anglia are calling for ambitious new targets to reduce energy demand across the European Union.

Math can save Tylenol overdose patients
University of Utah mathematicians developed a set of calculus equations to make it easier for doctors to save Tylenol overdose patients by quickly estimating how much painkiller they took, when they consumed it and whether they will require a liver transplant to survive.

In vino veritas: Promiscuous yeast hook up in wine-making vats, Stanford study shows
Humans aren't the only species that like to get busy with a glass of bubbly, according to researchers at the Stanford University School of Medicine.

Dental pulp stem cells transformed by 'bad breath' chemical
Japanese scientists have found that the odorous compound responsible for halitosis -- otherwise known as bad breath -- is ideal for harvesting stem cells taken from human dental pulp.

How to rescue the immune system
In a study published in Nature Medicine, Loyola researchers report on a promising new technique that potentially could turn immune system killer T cells into more effective weapons against infections and possibly cancer.
