Novel mechanism may help explain the virulence of 1918 'Spanish' flu

While yearly outbreaks of flu kill about 250,000 to 500,000 people worldwide, the 1918 "Spanish" flu infected one-third of the world's population and killed 50 million to 100 million. Chad Petit, Ph.D., assistant professor in the University of Alabama at Birmingham Department of Biochemistry and Molecular Genetics, has discovered a novel mechanism for one 1918 flu virus protein that may help explain the virulence of that unusually deadly pandemic.

Johns Hopkins scientists discover earliest premalignant genetic changes that mark potential onset of lung cancer

Working with tissue, blood and DNA from six people with precancerous and cancerous lung lesions, a team of Johns Hopkins scientists has identified what it believes are among the very earliest “premalignant” genetic changes that mark the potential onset of the most common and deadliest form of disease.

TSRI study reveals key morphine regulator that may help develop less-addictive pain medications

Once used in the 18th century as currency to reverse the trade imbalance between China and Britain, opiates that contain morphine have been misunderstood almost continually ever since.

UF researchers create fungi database to promote healthier environments

University of Florida Assistant Professor Matthew E. Smith is readying millions of fungi specimens for their close-ups. He and members of his team are helping to take photographs of and catalogue 2.3 million microfungi specimens for a worldwide database of mushrooms, truffles, molds and mildews, among other types of fungi.

Innovative detector could expand use of polarized light for drug screening, surveillance

Invention of the first integrated circularly polarized light detector on a silicon chip opens the door for development of small, portable sensors that could expand the use of polarized light for drug screening, surveillance, optical communications and quantum computing, among other potential applications.

Healthy adults with larger orbitofrontal cortex are more optimistic, less anxious

A new study links anxiety, a brain structure called the orbitofrontal cortex, and optimism, finding that healthy adults who have larger OFCs tend to be more optimistic and less anxious.

Reduced conflict-related brain activity linked to higher risk for psychosis

Researchers led by Bradley S. Peterson, MD, director of the Institute for the Developing Mind at Children's Hospital Los Angeles, have shown that lower levels of conflict-related brain activity are associated with a higher risk for later psychosis.

University of Adelaide study sheds light on the activity of cancer-suppressing gene

University of Adelaide researchers have uncovered the role played by a gene which suppresses the development of cancer. The findings, published in the journal PLOS ONE, open new opportunities for scientists to find treatments for cancer.

Study demonstrates potential of FCPCs as new source for cartilage regeneration

The self-repair of injured cartilage is difficult for several reasons, foremost of which is the lack of blood supply to the tissue. Therapeutic efforts aimed at cartilage repair are often not optimal. Surgical repair techniques often lead to the formation of fibrocartilage, which is weaker and less durable. Although cell transplantation aimed at cartilage repair has been carried out using mesenchymal stem cells (MSCs), varying outcomes have resulted, despite the propensity of MSCs to proliferate and differentiate.

Researchers receive $13 million NIH grant to develop new stem cell-based assays for studying autism

The National Institutes of Health has awarded a $13 million grant over five years to develop and disseminate new stem cell-based technologies and assays for studying autism spectrum disorder (ASD) and other mental health diseases to a consortium of researchers at the University of California, San Diego and the Salk Institute for Biological Studies, working in tandem with leaders in the biotechnology sector.

Findings may suggest new therapeutic target to combat memory loss in aging, Alzheimer's disease

Northwestern Medicine scientists have examined activity in a little-studied part of the brain associated with memory and found for the first time the reason that neurons there become more active in old age, findings that may suggest a new target for future therapies to combat memory loss in aging and Alzheimer's disease.

University of Alberta researchers discover diabetes 'dimmer' switch

Patrick MacDonald has dedicated much of his life to diabetes research. It's a job he knows is far too large and complex for any one person, but with his latest publication, he knows his work is playing a part.

Mayo Clinic's Gianrico Farrugia highlights five areas that may impact patient care

How is individualized medicine working? Let us count the ways. That's just what Mayo Clinic Vice President Gianrico Farrugia, M.D., did this morning in his opening keynote at the 4th annual Individualizing Medicine Conference. The core of his talk highlighted five areas in which the knowledge and know-how from the human genome will be most impactful in patient care, not just at Mayo Clinic, but anywhere in the nation and globally.

UCSF researchers successfully separate human muscle stem cells

UC San Francisco researchers have successfully isolated human muscle stem cells and shown that the cells could robustly replicate and repair damaged muscles when grafted onto an injured site. The laboratory finding paves the way for potential treatments for patients with severe muscle injury, paralysis or genetic diseases such as muscular dystrophy.
