Less Surveillance Needed for Simple Ovarian Cysts

Simple ovarian cysts are extremely common in women and do not require additional ultrasound surveillance or surgical removal, according to a new study of more than 72,000 women and close to 119,00 pelvic ultrasound exams over a dozen years. The study, a collaboration between UC San Francisco and Kaiser Permanente Washington, found that simple cysts are normal, extremely common in both pre- […]

Suicide Handshakes Kill Precursor T Cells that Pose Autoimmune Dangers

Ball lands in cup; cup triggers spring; spring clamps lever tightly onto ball. That’s a rough description of newly discovered cellular mechanisms that eliminate T cells that may cause autoimmune disorders. Although the mechanisms are intertwined with biochemical processes, they also work mechanically, grasping, tugging and clamping, say researchers at the Georgia Institute […]

Poor nutrition ruled out as cause for obesity in adults abused as children

In a new study, recently published in the journal Preventive Medicine, Assistant Professor Susan Mason from the University of Minnesota School of Public Health ruled out poor food choices and eating practices in the childhood home as a major factor in the development of obesity in adults who were maltreated. Mason acquired observational survey data […]

Stripping the Linchpins From the Life-Making Machine Reaffirms Its Seminal Evolution

So audacious was Marcus Bray’s experiment that even he feared it would fail. In the system inside cells that translates genetic code into life, he replaced about 1,000 essential linchpins with primitive substitutes to see if the translational system would survive and function. It seemed impossible, yet it worked swimmingly, […]

Scientists simplify and accelerate directed evolution bioengineering method

In a process known as directed evolution, scientists reengineer biomolecules to find ones that perform beneficial new functions. The field is revolutionizing drug development, chemical engineering and other applications, but to realize its promise involves painstaking and time-consuming laboratory work. In a study published in the journal Cell, University of California, […]

‘Orphan’ RNAs Make Cancer Deadlier, But Potentially Easier to Diagnose

Scientists have long known that cancer can hijack a cell’s existing regulatory circuitry and transform healthy cells into deadly malignancies. But a new discovery from UC San Francisco demonstrates that cancer is more than just a mutineer that seizes control of the cell’s administrative operations – it’s also a clever […]

Scanning blood vessels in the neck could help predicting the risk of dementia

Sadly, dementia is in the cards for many people. Detected early it can be slowed down, which is why scientists are looking for new, more accurate early diagnosis measures. Now researchers at UCL have found that neck scan could predict risk of developing cognitive decline. This new idea is based […]

Community Choirs Reduce Loneliness and Increase Interest in Life for Older Adults

An innovative San Francisco program of community choirs for older adults found that singing in a choir reduced loneliness and increased interest in life, but did not improve cognition or physical function, according to a study by researchers at UC San Francisco. The program – Community of Voices – was a collaboration […]

Montreal Researchers Explain How Your Muscles Form

All vertebrates need muscles to function; they are the most abundant tissue in the human body and are integral to movement. In a recent article published in Nature Communications, an international team of researchers discovered two proteins essential to the development of skeletal muscle. This research, led by Jean-François Côté, a […]

Embryos remember the chemicals that they encounter

We all start out as a clump of identical cells. As these cells divide and multiply, they gradually take on distinct identities, acquiring the traits necessary to form, for instance, muscle tissue, bone, or nerves. A recent study from Rockefeller scientists offers new insight into how these cellular identities are […]

Scientists shine new light on link between obesity and cancer

Scientists have made a major discovery that shines a new, explanatory light on the link between obesity and cancer. Their research confirms why the body’s immune surveillance systems – led by cancer-fighting Natural Killer cells – stutter and fail in the presence of excess fat. Additionally, it outlines possible paths […]
