Seoul virus outbreak associated with home-based rat-breeding facilities

Posted: 20 Jan 2017 12:43 PM PST

Experts from CDC are working with the Illinois Department of Health and the Wisconsin Department of Health Services to investigate cases of Seoul virus infections among eight people who worked at several rat-breeding facilities in the two states. Seoul virus is not commonly found in the United States, though there have been several reported outbreaks in wild rats. This is the first known outbreak associated with pet rats in the United States.

The first molecular study of an organism able to survive intracellular freezing (freezing within its cells) is published in a new paper that represents a milestone in scientists' understanding of an extraordinary adaptation.

Tracking movement of immune cells identifies key first steps in inflammatory arthritis

Using a novel approach for imaging the movement of immune cells in living animals, researchers have identified what appear to be the initial steps leading to joint inflammation in a model of inflammatory arthritis.

Researchers unlock mechanism of drug resistance in aggressive breast cancer

Posted: 20 Jan 2017 09:11 AM PST

Scientists report findings of how triple negative breast cancer cells are able to bypass treatment with trametinib, a U.S. Food and Drug Administration-approved drug that belongs to a class of commonly used anti-cancer drugs called kinase inhibitors. The researchers also reported findings from laboratory models of breast cancer testing a potential treatment approach that could prevent the onset of resistance.

New 'smart needle' to make brain surgery safer

A new high-tech medical device to make brain surgery safer has now been developed.

New genetic engineering technique could help design, study biological systems

Posted: 20 Jan 2017 06:10 AM PST

A new technique will help biologists tinker with genes, whether the goal is to turn cells into tiny factories churning out medicines, modify crops to grow with limited water or study the effects of a gene on human health. The technique allows scientists to precisely regulate how much protein is produced from a particular gene. The process is simple yet innovative and, so far, works in everything from bacteria to plants to human cells.

Number of women who take maternity leave has stalled

Posted: 20 Jan 2017 06:06 AM PST

The number of U.S. women taking maternity leave has not changed in 22 years despite factors that suggest it should be increasing, a new study found. During the same time, the number of fathers taking paternity leave more than tripled.

Think binge drinking is safer for your liver than regular heavy drinking? Think again

Posted: 20 Jan 2017 06:06 AM PST

Alcoholic liver disease (ALD) occurs on a spectrum of severity. The majority of people who drink excessively develop a fatty liver, which though often symptom free, can progress to a state of inflammation, fibrosis, and cell death that can be fatal. Little is known about liver disruption that may occur in problem drinkers who are not alcohol dependent. To help understand the development of ALD, this study used a rodent model to examine differences in liver damage between binge drinkers and heavy drinkers.

Pancreatic tumors rely on signals from surrounding cells
