Want to be a supercentenarian? The chances of reaching the ripe old age of 110 are within reach – if you survive the perilous 90s and make it to 105 when death rates level out, according to a study of extremely old Italians led by UC Berkeley and Sapienza University […]

University of Nebraska–Lincoln psychologist Maital Neta aims to find out why people interpret ambiguous everyday events — are they whispering about me? — more favorably as they get older. Her research could one day help inform treatment options for depression, anxiety and similar maladies. Neta has earned a $756,611 Faculty Early Career […]

Most cells in the human body have a cilium, a slender cell protuberance that picks up signals from the cell's external environment. Researchers at the University of Zurich have now shown that these fine sensory antennae play a key role in the formation of melanoma. When cilia are prevented from […]

In a new study published online in Nature Medicine, UC San Francisco researchers have identified a key biological pathway in human cancer patients that appears to prime the immune system for a successful response to immunotherapy drugs known as checkpoint inhibitors. The findings, including initial observations from human tumor samples, mechanistic […]

More than 60 percent of breast cancer cases involve defects in the same biochemical chain of events within cancer cells — known as the PI3 kinase (PI3K) pathway — but efforts to develop therapies targeting this pathway have met with little success after hundreds of mostly failed clinical trials. And […]

Many cases of early-stage kidney cancer can be treated with a relatively new, nonsurgical procedure used to destroy tumors, a study by a team led by Weill Cornell Medicine and NewYork-Presbyterian suggests. The procedure, called percutaneous ablation, involves the insertion of a needle through the skin into a kidney tumor, […]

A tumor’s goal is simple: to grow, grow, grow, by making more cancer cells. But that often means growing so fast that the oxygen supply gets scarce, at which point cells within the tumor start to suffocate. Without oxygen, these ever-dividing cells struggle to make enough aspartate, a crucial ingredient […]

Remove tumor cells from a living organism and place them in a dish, and they will multiply even faster than before. The mystery of why this is has long stumped cancer researchers, though many have simply focused on the mutations and chains of molecular reactions that could prompt such a […]

Men with non-metastatic castrate-resistant prostate cancer and a quickly rising PSA level present a medical dilemma. The rising PSA (prostate-specific antigen) means there is cancer activity, but no visible metastasis in a scan. These men are receiving hormone treatments to reduce the testosterone on which their cancer feeds, but their cancers […]

Need to kill tumors? Just add heat. That’s the promise of heated magnetic nanoparticles, a futuristic-sounding technology that could one day be used to fry and eradicate cancer cells without harming healthy tissue elsewhere in the body.
