The Viking journey of mice and men
House mice happily live wherever there are humans. When populations of humans migrate the mice often travel with them.

UMass Amherst theoretical physicists find a way to simulate strongly correlated fermions
The paper includes crucial results of an experimental validation conducted by Martin Zwierlein and colleagues at MIT.

Marine Protected Areas are keeping turtles safe
Marine Protected Areas are providing sea turtles with an ideal habitat for foraging and may be keeping them safe from the threats of fishing.

American College of Cardiology honors 2 Cedars-Sinai Heart Institute physicians
Two physicians from the Cedars-Sinai Heart Institute will receive the American College of Cardiology's highest honors for scientific research and clinical care during the organization's upcoming annual scientific meeting in Chicago.

Exotic materials will change optics, Duke researchers say
Duke University engineers believe that continued advances in creating ever-more exotic and sophisticated man-made materials will greatly improve their ability to control light at will.

Columbia Engineering and Penn researchers increase speed of single-molecule measurements
Columbia Engineering researchers, together with colleagues at the University of Pennsylvania, have devised a way to measure nanopores -- tiny holes in a thin membrane that can detect single biological molecules such as DNA and proteins -- with less error than can be achieved with commercial instruments.

Stanford researchers boost potency, reduce side effects of IL-2 protein used to treat cancer
The utility of a naturally occurring protein given, sometimes to great effect, as a drug to treat advanced cancers is limited by the severe side effects it sometimes causes.

Researchers reveal how a single gene mutation leads to uncontrolled obesity
Researchers at Georgetown University Medical Center have revealed how a mutation in a single gene is responsible for the inability of neurons to effectively pass along appetite suppressing signals from the body to the right place in the brain.

Bone marrow transplant arrests symptoms in model of Rett syndrome
A paper published today in Nature describes the results of using bone marrow transplant to replace faulty immune system cells in models of Rett syndrome.

The Japanese traditional therapy, honokiol, blocks key protein in inflammatory brain damage
Microglia are the first line defense of the brain and are constantly looking for infections to fight off.

Tracking proteins behaving badly provides insights for treatments of brain diseases
A research team led by the University of Melbourne, Australia, has developed a novel technique that tracks diseased proteins behaving badly by forming clusters in brain diseases such as Huntington's and Alzheimer's.

Genetic variation in East Asians found to explain resistance to cancer drugs
A multi-national research team led by scientists at Duke-NUS Graduate Medical School has identified the reason why some patients fail to respond to some of the most successful cancer drugs.

New insight into mechanisms behind autoimmune diseases suggests a potential therapy
A mutant form of a protein called LYP has been implicated in multiple autoimmune diseases, but the precise molecular pathway involved has been unknown.

Hazy shades of life on early Earth
When microbes ruled the world -- new research provides evidence of the key role played by microorganisms in the creation of our atmosphere and the development of complex life on Earth.

Need for speed
In fruit fly egg cells, oskar RNA carries a stamped ticket detailing its destination and guaranteeing it will travel fast enough, scientists at EMBL Heidelberg have found.

Looking at quantum gravity in a mirror
Einstein's theory of gravity and quantum physics are expected to merge at the Planck-scale of extremely high energies and on very short distances.

A surprising new kind of proton transfer
Common wisdom has it that protons only travel between molecules via hydrogen bonds: no hydrogen bonds, no proton transfer.

Fox Chase Cancer Center leads efforts to establish national standards for survivorship care
People are living longer with and after a cancer diagnosis, making survivorship clinics and programs -- as well as official guidelines and practices governing the care of survivors -- an important emerging component of modern cancer care.
