Study reveals strain of V. cholerae in Haiti cholera outbreak originated from single source

The strain of cholera that has sickened thousands in Haiti came from a single source and was not repeatedly introduced to the island over the past three years as some have thought, according to a new study published in mBio-, the online open-access journal of the American Society for Microbiology.

Cerebral aneurysms are more likely to rupture if they grow in size

Cerebral aneurysms of all sizes-even small ones below seven millimeters-are 12 times more likely to rupture if they are growing in size, according to a new study published online in the journal Radiology.

Low levels of amyloid fibres are more harmful to health, say scientists

Neurodegenerative diseases such as Alzheimer's could be better understood thanks to insight into proteins linked to such conditions, a study suggests.

Father's lifestyle has potential to affect DNA of multiple generations

Gene mutations caused by a father's lifestyle can be inherited by his children, even if those mutations occurred before conception. What's more, these findings show that mutations in the germ-line are present in all cells of the children, including their own germ cells. This means that a father's lifestyle has the potential to affect the DNA of multiple generations and not just his immediate offspring. These findings were published in the July 2013 issue of The FASEB Journal.

RORA: A novel candidate gene for autism regulates large number of other genes

A new study by Valerie Hu, Ph.D., professor of biochemistry and molecular medicine at the George Washington University (GW) School of Medicine and Health Sciences (SMHS), reports that RORA, a novel candidate gene for autism discovered by her group in a 2010 study, regulates a large number of other genes associated with autism.

DNA fragments in blood may help doctors to quickly identify coronary artery disease

DNA fragments in your blood may someday help doctors quickly learn if chest pain means you have narrowed heart arteries, according to a new study published in the American Heart Association journal Arteriosclerosis, Thrombosis, and Vascular Biology.

Arizona State University physicist explains new theory of cancer

With death rates from cancer have remained largely unchanged over the past 60 years, a physicist is trying to shed more light on the disease with a very different theory of its origin that traces cancer back to the dawn of multicellularity more than a billion years ago.

Researchers discover an important mechanism that regulates proteasome activity

Dysfunction of the ubiquitin-proteasome system (UPS) has been detected in many neurodegenerative diseases, such as Alzheimer's and Parkinson's diseases, and certain types of cancer. Such dysfunction is also believed to be related to some degenerative muscle diseases. Researchers at the University of Helsinki, Finland, have now discovered an important mechanism that regulates proteasome activity.

Researchers find fear can increase or decrease ability to discriminate among sounds depending on context

Anyone who's ever heard a Beethoven sonata or a Beatles song knows how powerfully sound can affect our emotions. But it can work the other way as well - our emotions can actually affect how we hear and process sound.

Protein in liver plays a crucial role in mice's pregnancy and human menstrual cycle

A protein first shown to function in the liver plays a crucial role in pregnancy in mice and has a key role in the human menstrual cycle, according to researchers at the University of Montreal. Mice that were genetically engineered not to produce the liver receptor homolog-1 (Lrh-1) molecule were unable to create the uterine conditions necessary for establishing and sustaining pregnancy, resulting in the formation of defective placentas.

Scientists identify neuronal circuits in spinal cord control limb alternation during walking

Scientists at Karolinska Institutet in Sweden have identified the neuronal circuits in the spinal cord of mice that control the ability to produce the alternating movements of the legs during walking.

Research: Systemic dose of dendritic cells prevent rejection in kidney transplantation

A single systemic dose of special immune cells prevented rejection for almost four months in a preclinical animal model of kidney transplantation, according to experts at the University of Pittsburgh School of Medicine.

Tiny RNA molecules work as powerful regulators of immune response in mammals

A team led by scientists at The Scripps Research Institute (TSRI) has identified a family of tiny RNA molecules that work as powerful regulators of the immune response in mammals. Mice who lack these RNA molecules lose their normal infection-fighting ability, whereas mice that overproduce them develop a fatal autoimmune syndrome.

Study shows autophagy blockers play a role in treatment of non-small-cell lung cancer

New research from Rutgers Cancer Institute of New Jersey, Princeton University and other collaborators suggests that inactivation of an essential gene responsible for the cell survival process known as autophagy can suppress the growth of non-small-cell lung cancer tumors and render them more benign.

Biomolecular interactions of nanoparticles can improve drug development, optical sensors and more

In chemical reactions, left and right can make a big difference. A "left-handed" molecule of a particular chemical composition could be an effective drug, while its mirror-image "right-handed" counterpart could be completely inactive.

Synthetic biology technology could lead to new antibiotics, modified protein-generators

Synthetic biology researchers at Northwestern University, working with partners at Harvard Medical School, have for the first time synthesized ribosomes -- cell structures responsible for generating all proteins and enzymes in our bodies -- from scratch in a test tube.

Study shows lymphatic circulatory system may be intimately involved in vascular disorders

The often forgotten lymphatic circulatory system may be intimately involved in vascular disorders, according to a study by researchers from The University of Texas Health Science Center at Houston (UTHealth) and University of Michigan. Their research was reported recently in the Proceedings of the National Academy of Sciences.

Researchers develop new drug delivery systems to treat cancer by blocking signaling receptor

A cardiac hormone signaling receptor abundantly expressed both in inflamed tissues and cancers appears to recruit stem cells that form the blood vessels needed to feed tumor growth, reports a new study by scientists at the University of South Florida Nanomedicine Research Center.

Ecology, evolution of infectious diseases to be highlighted at ESA's annual meeting

West Nile virus, Lyme disease and hantavirus. All are infectious diseases spreading in animals and in people. Is human interaction with the environment somehow responsible for the increase in these diseases? The ecology and evolution of infectious diseases will be highlighted at two symposia at the Ecological Society of America's annual meeting, held from Aug. 5-9 in Minneapolis, Minn.
