New way to image how brain cells coordinate with each other to control specific behaviors

A team led by MIT neuroscientists has developed a way to monitor how brain cells coordinate with each other to control specific behaviors, such as initiating movement or detecting an odor.

Recurrent patterns of genomic imbalances determine evolution of invasive breast cancer

Ductal carcinoma in situ (DCIS) is considered a precursor lesion for invasive breast cancer if untreated, and is found in approximately 45% of patients with invasive ductal carcinoma (IDC). Patients with DCIS only (not accompanied by invasive disease) have a 5-year-survival of nearly 100%, compared to 89% for all stages of invasive breast cancer (24% for patients with distant metastasis).

Male infertility linked to an enzyme complex issue

An enzyme complex present in sperm plasma membranes plays an important role in the overproduction of reactive oxygen species and oxidative stress in sperm with abnormal morphology, researchers have shown.

Inscopix to introduce nVista HD at Neuroscience 2012

Inscopix, Inc. will announce the launch of nVista HD, an end-to-end solution for in vivo brain imaging in freely behaving mice, this weekend at Neuroscience 2012 (SfN).

New mechanism may alter principle understandings of molecular interactions within a cell's nucleus

Scientists at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory, with collaborators from Harvard University, the University of Madrid, Princeton University, and the University of Zurich, have discovered a new mechanism that may alter principle understandings of molecular interactions within a cell's nucleus.

Study sheds light on fundamental cellular process

Scientists at the Gladstone Institutes have mapped the precise frequency by which genes get turned on across the human genome, providing new insight into the most fundamental of cellular processes-and revealing new clues as to what happens when this process goes awry.

Novel technology can identify potential biomarkers of ulcerative colitis

Scientists from the Florida campus of The Scripps Research Institute have developed a novel technology that can identify, in animal models, potential biomarkers of ulcerative colitis, a type of inflammatory bowel disease that affects the lining of the colon.

U.S. Pharmacopeial announces winners of 2012-13 Global Fellowship awards

Since the program's inception more than thirty years ago, USP has invested nearly $4 million in over 200 fellowship awards.

New understanding about function of MYC proteins

Scientists may have discovered why a protein called MYC can provoke a variety of cancers. Like many proteins associated with cancer, MYC helps regulate cell growth. A study carried out by researchers at the National Institutes of Health and colleagues found that, unlike many other cell growth regulators, MYC does not turn genes on or off, but instead boosts the expression of genes that are already turned on.

New spray could help avoid contact dermatitis

With more than half of all adults allergic to poison ivy, oak and sumac, scientists are reporting an advance toward an inexpensive spray that could reveal the presence of the rash-causing toxic oil on the skin, clothing, garden tools, and even the family cat or dog. Using the spray, described in ACS' The Journal of Organic Chemistry would enable people to wash off the oil, or avoid further contact, in time to sidestep days of misery.

Study elucidates memory-forming signal transmission in the hippocampus

The hippocampus represents an important brain structure for learning. Scientists at the Max Planck Institute of Psychiatry in Munich discovered how it filters electrical neuronal signals through an input and output control, thus regulating learning and memory processes.

Adult stem cells can prevent Alzheimer's disease

In the first study of its kind, researchers at Korea's leading university and the RNL Bio Stem Cell Technology Institute announced this week the results of a study that suggests an astounding possibility: adult stem cells may not only have a positive effect on those suffering from Alzheimer's disease, they can prevent the disease.

k-MITOMI device can simultaneously measure up to 768 biomolecular interactions

Inside our cells, molecules are constantly binding and separating from one another. It's this game of constant flux that drives gene expression asides essentially every other biological process.

New nanotechnology detects micrometastases in mouse models of breast cancer

Malignant cells that leave a primary tumor, travel the bloodstream and grow out of control in new locations cause the vast majority of cancer deaths. New nanotechnology developed at Case Western Reserve University detects these metastases in mouse models of breast cancer far earlier than current methods, a step toward earlier, life-saving diagnosis and treatment.

Lasers manipulate neurons in worms' brains

In the quest to understand how the brain turns sensory input into behavior, Harvard scientists have crossed a major threshold. Using precisely-targeted lasers, researchers have been able to take over an animal's brain, instruct it to turn in any direction they choose, and even to implant false sensory information, fooling the animal into thinking food was nearby.

Nanoparticles for non-invasive photodynamic therapy of deep cancer

National University of Singapore researchers at the Faculty of Engineering's Department of Bioengineering have discovered a new technology that paves the way for a new safe and non-invasive method of treating deep cancer. Led by Associate Professor Zhang Yong, the team has so far, proven that their technology could inhibit tumour growth and control gene expression in mice. This is a world's first for the use of nanoparticles for non-invasive photodynamic therapy of deep cancer.

Researchers regenerate axons at spinal cord injury site

In a study at the University of California, San Diego and VA San Diego Healthcare, researchers were able to regenerate "an astonishing degree" of axonal growth at the site of severe spinal cord injury in rats.

UMass Amherst develops 'chemical nose' array to detect metastatic cancers

In the fight against cancer, knowing the enemy's exact identity is crucial for diagnosis and treatment, especially in metastatic cancers, those that spread between organs and tissues. Now chemists led by Vincent Rotello at the University of Massachusetts Amherst have developed a rapid, sensitive way to detect microscopic levels of many different metastatic cell types in living tissue. Findings appear in the current issue of the journal ACS Nano.

Some gut microbes increase absorption of dietary fats

You may think you have dinner all to yourself, but you're actually sharing it with a vast community of microbes waiting within your digestive tract. A new study from a team including Carnegie's Steve Farber and Juliana Carten reveals that some gut microbes increase the absorption of dietary fats, allowing the host organism to extract more calories from the same amount of food.
