Controlling the Shape-Shifting Skeletons of Cells

You know you have a skeleton, but did you know that your cells have skeletons, too? Cellular skeletons, or cytoskeletons, are shapeshifting networks of tiny protein filaments, enabling cells to propel themselves, carry cargo, and divide. Now, an interdisciplinary team of Caltech researchers has designed a way to study and […]

Electromagnetic fields may hinder spread of breast cancer cells

Electromagnetic fields might help prevent some breast cancers from spreading to other parts of the body, new research has found. The study showed that low intensity electromagnetic fields hindered the mobility of specific breast cancer cells by preventing the formation of long, thin extensions at the edge of a migrating […]

NIH researchers uncover role of repetitive DNA and protein sequences in tumor evolution

A team of researchers from the National Library of Medicine (NLM), part of the National Institutes of Health, and collaborating academic research institutions developed a method to measure a type of gene mutation involved in the evolution of cancer. This type of mutation, called “repeat instability,” may be useful in […]

The brain’s amyloid buildup is not a powerful indicator of Alzheimer’s disease

While the presence of beta-amyloid plaques in the brain may be a hallmark of Alzheimer’s disease, giving patients an amyloid PET scan is not an effective method for measuring their cognitive function, according to a new study from researchers in the Perelman School of Medicine and Thomas Jefferson University. The […]

Researchers reverse engineer the ‘fireworks of life’

Imagine standing in a lumberyard and being asked to build a house — without blueprints or instructions of any kind. The materials are all in front of you, but that doesn’t mean you have the first idea how to get from point A to point B. That was the situation […]

Probing the Origin of Alzheimer's… with Transistors

Novel high-sensitivity detector could aid in early diagnosis. A prime suspect in the onset of Alzheimer’s and Parkinson’s diseases is a normally benign enzyme that is essential to proper development of the nervous system. Under certain conditions, however, its chemical structure changes and it goes rogue, contributing to the neural […]

Beyond DNA

Pretty much all of your cells have the same DNA code, yet they come in an astonishing number of forms. Some cells contract so the heart can beat or your muscles flex. Others have jobs in the immune system, tuned to recognize different threats. Cells can change their behavior, altering […]

Blood test is highly accurate at identifying Alzheimer’s before symptoms arise

Up to two decades before people develop the characteristic memory loss and confusion of Alzheimer’s disease, damaging clumps of protein start to build up in their brains. Now, a blood test to detect such early brain changes has moved one step closer to clinical use. Researchers from Washington University School […]

Dancin’ to the Music: More than Just Exercise

“Music evokes emotion, and emotion can bring with it memory… it brings back the feeling of life when nothing else can.” This quote by well-known British neurologist Oliver Sacks (author of Awakenings) shows the power of music. Indeed, like the aroma of cookies baking, a familiar song can bring us back to […]

Most Seniors with Dementia Live at Home, Despite Pain, Anxiety, Poor Health

Contrary to popular belief, most older Americans with advancing dementia remain in their own homes — many until they die. But a new study by researchers at UC San Francisco has revealed that this population may endure more pain and have more complex or unaddressed medical needs than their counterparts […]

1 in 300 Thrives on Very-Early-to-Bed, Very-Early-to-Rise Routine

A quirk of the body clock that lures some people to sleep at 8 p.m., enabling them to greet the new day as early as 4 a.m., may be significantly more common than previously believed. So-called advanced sleep phase — previously believed to be very rare — may affect at […]

Cell combo might unlock a heart repair strategy

A combination of two different kinds of heart cells, derived from stem cells, might be key to designing an effective graft for repairing damaged hearts. During embryonic development, cells originating in the epicardium – the protective outer wall of the heart – are pivotal in certain aspects of how the […]

Researchers take key step toward cancer treatments that leave healthy cells unharmed

Researchers have opened up a possible avenue for new cancer therapies that don’t have the side effects that oftentimes accompany many current cancer treatments by identifying a protein modification that specifically supports proliferation and survival of tumor cells. Depending on the kind of cancer and the type of treatment, a […]

Paper trail leads to heart valve discoveries

Paper is at the heart of an experimental device developed by Rice University bioengineers to study heart disease. They are using paper-based structures that mimic the layered nature of aortic valves, the tough, flexible tissues that keep blood flowing through the heart in one direction only. The devices allow the engineers […]

Transgender Women Can Regain Fertility Shows Case Study

Scientists at Magee-Womens Research Institute (MWRI), collaborating with clinicians at UPMC Magee-Womens Hospital and UPMC Children’s Hospital of Pittsburgh report two cases in which young transgender women attempted to recover their fertility after starting and stopping gender-affirming medications. The study, published in Pediatrics, found that one transgender woman was able to produce viable sperm after a […]

Scientists discover immune cell subtype in mice that drives allergic reactions

Allergies can be life-threatening when they cause anaphylaxis, an extreme reaction with constriction of the airways and a sudden drop in blood pressure. Scientists have identified a subtype of immune cell that drives the production of antibodies(link is external) associated with anaphylaxis and other allergic reactions. The research was funded by […]

Clinical trial to evaluate experimental treatment in people allergic to multiple foods

Though food allergy affects more than 4.8 million children in the United States, no approved preventative treatments currently exist. While experimental desensitization strategies are available in research settings, people with food allergies must avoid known allergens and are advised to carry injectable epinephrine to prevent potentially life-threatening allergic reactions caused […]

Liver Damage More Commonly Due to Malignant Tumors than Cancer Immunotherapy Drug

Immunotherapy as a treatment for advanced solid organ tumors has rapidly evolved over the past decade, often yielding remarkable results. However, its use has also given way to new adverse effects, including drug-induced gastrointestinal and liver toxicities. “Checkpoint inhibitors are a game changer for a lot of oncology patients with […]
