Targeting Stem-Like Cells Prevents Ovarian Cancer Recurrence

Ovarian cancer is not the most common form of cancer, but it’s among the deadliest. That’s because about 70 percent of cases recur. A new study by researchers at the University of Pittsburgh, UPMC Hillman Cancer Center, Magee-Womens Research Institute (MWRI) and several other collaborating institutions targets the root of recurrence with new drugs […]

Artificial Intelligence Cuts Lung Cancer False Positives

Lung cancer is the leading cause of cancer deaths worldwide. Screening is key for early detection and increased survival, but the current method has a 96 percent false positive rate. Using machine learning, researchers at the University of Pittsburgh and UPMC Hillman Cancer Center have found a way to substantially reduce false positives without […]

Forgetting requires more Conscious Effort than Remembering, Study Finds

Despite the decades of research on the brain‘s ability to voluntarily discard certain memories, scientists are still trying to pin down the mechanism behind it, which could eventually allow mental health professionals to offer their patients the option of getting rid of memories which trigger involuntary, maladaptive responses. Now, a […]

Scientists identify genetic factors that may cause some people to become obese

Obesity is a major public-health problem in the United States and around the world, with an estimated 650 million people suffering from the condition. One of the biggest challenges of this ever-worsening condition is figuring out why people become obese in the first place, and why some people are more […]

Insulin protects against colorectal cancer

Excess weight promotes the development of insulin resistance and the incidence of colon cancer. Scientists from the Max Planck Institute for Metabolic Research in Cologne identified a new mechanism of the insulin signaling in the intestinal mucosa, which is responsible for maintaining the intestinal barrier and explains the connection between […]

Electrifying wound care: Better bandages to destroy bacteria

Bandages infused with electricity can help heal wounds faster than typical bandages or antibiotics—but for years, researchers have not really understood why. A recent study by a team at The Ohio State University is offering new clues about the science behind those bandages, and researchers say the findings could help […]

New optical imaging system could be deployed to find tiny tumors

Many types of cancer could be more easily treated if they were detected at an earlier stage. MIT researchers have now developed an imaging system, named “DOLPHIN,” which could enable them to find tiny tumors, as small as a couple of hundred cells, deep within the body. In a new […]

New CRISPR technique for studying gene function developed

When researchers want to understand a gene’s function, they silence or disable that gene in a model organism, such as a fruit fly, and then look for unusual effects on the fly. This is referred to as creating loss-of-function, or “knocking out” a gene. A study published in the journal […]

Researchers find high blood pressure link

Early onset menstruation linked to high blood pressure in late adulthood, UGA study finds. The age a woman begins menstruation is associated with having high blood pressure later in her life, according to a team of researchers at the University of Georgia. Specifically, researchers found that early onset menstruation significantly increased […]

Pregnancy infection increases a child’s autism, suicide risk

Children whose mothers were hospitalized with an infection during pregnancy may be at increased risk for autism, depression and suicide later in life, according to a new study by researchers at the University of Washington School of Medicine in Seattle, Washington, and the Sahlgrenska Academy in Gothenburg, Sweden. Previous research […]

Embryos’ signals take multiple paths

Rice University scientists have found significant differences between the methods signaling pathways use to prompt cells to differentiate – that is, whether to become organs, bone, blood vessels, nerves or skin. Rice bioscientist Aryeh Warmflash and alumnus Idse Heemskerk led a team that discovered stem cells are sensitive not only to the signals that […]

New Insight into Aging Hearts

A team led by Harvard Medical School researchers based at Massachusetts General Hospital has found that activity of an important signaling pathway increases with aging and with heart failure. In a report published in Science Translational Medicine, the team describes evidence from both humans and animal models that increased activin type II […]

‘Game changer’ in treatment of chronic lymphocytic leukaemia

The Cardiff researchers say that the test could now be a ‘game changer’ in the treatment of chronic lymphocytic leukaemia (CLL). It also has the potential to change how other cancers, including myeloma and breast cancer, are treated. While previous versions of the test had taken a week to process, […]

Using sleep disorder to predict Parkinson’s disease

A large multi-centre study of more than 1,200 patients provides important predictors of Parkinson’s disease progression, which will allow better candidate selection for clinical trials and more effective therapy development. The study, led by Dr. Ron Postuma at The Neuro (Montreal Neurological Institute and Hospital) and the Montreal General Hospital […]

Genomics Could Guide Pancreatic Cancer Treatment

Pancreatic cancer is a grim diagnosis, with a five-year survival rate of less than 9 percent. To improve those odds, researchers at UPMC and the University of Pittsburgh School of Medicine sought genetic signatures in the largest study of its kind that could be used to better match drugs to patients and for early […]

Diet reverses Alzheimer’s-like symptoms in lab model

A diet containing compounds found in green tea and carrots reversed Alzheimer’s-like symptoms in mice genetically programmed to develop the disease, USC researchers say. Researchers emphasize that the study, published in the Journal of Biological Chemistry, was in mice, and many mouse discoveries never translate into human treatments. Nevertheless, the findings […]

Largest-Ever Alzheimer’s Gene Study Reveals Five New Genes that Increase Risk

The International Genomic Alzheimer’s Project (IGAP) analyzed information from more than 94,000 individuals and found new information on the underlying causes of Alzheimer disease (AD), including five new genes that increase risk for the disease. Their findings were published in Nature Genetics. The study, which was funded in part by the […]

The link between sleep, genes, and mental health

We’ve known for some time that sleep can affect a person’s risk for developing mental health problems. New research from Penn Medicine and a host of other institutions and organizations shows that whether you stay up until the wee hours or bound out of bed with the first rays of sunshine matters, […]

By Blocking Protein, Researchers Keep Brain Tumors from Repairing Themselves

Researchers at the San Diego branch of the Ludwig Institute for Cancer Research at University of California San Diego, with colleagues around the country, report that inhibiting activity of a specific protein in glioblastomas (GBM) boosts their sensitivity to radiation, thus improving treatment prospects for one of the most common […]
