In a novel study comparing healthy cells from people in their 20s with cells from people in their 80s, researchers say they have documented that cell division rates appear to consistently and markedly slow down in humans at older ages.
Read moreChronic stress during pregnancy triggers an immune response in the brain that has potential to alter brain functions in ways that could contribute to postpartum depression, new research in animals suggests.
Read moreScience tells us that a lot of good things happen in our brains while we sleep — learning and memories are consolidated and waste is removed, among other things. New research shows for the first time that important immune cells called microglia — which play an important role in reorganizing the connections between nerve cells, fighting infections, and repairing damage — are also primarily active while we sleep.
Read moreChemotherapy and radiation therapy are commonly used to treat cancer, but are not always effective and can have toxic side effects. Researchers tested a new radiotherapy technique that sends alpha-emitting particles to stroma cells in pancreatic tumors. The method slowed tumor growth in mice with minimal side effects, pointing to a new potential treatment option in the future for patients with pancreatic cancer.
Read moreThe study, conducted in mice, is the first to show that creatine uptake is critical to the anti-tumor activities of killer T cells, the foot soldiers of the immune system.
Read moreResearchers have developed a new cheap method that can identify highly heterogeneous tumors that tend to be very aggressive, and therefore need to be treated more aggressively.
Read moreScientists are developing powerful new devices and technologies to monitor and regulate brain activity. To ensure NIH keeps pace with rapid technological development and help clinicians and researchers ethically fit these new tools into practice, a new article highlights potential issues around and offers recommendations about clinical research with both invasive and noninvasive neural devices.
Read moreA compound effective in killing chemotherapy-resistant glioblastoma-initiating cells (GICs) has been identified, raising hopes of producing drugs capable of eradicating refractory tumors with low toxicity.
Read moreNon-invasive brain stimulation is to be trialled for the first time alongside advanced brain imaging techniques in patients who are minimally conscious or in a vegetative state.
Read moreResearchers have identified a targeted therapy for adolescent patients with neuroblastoma, a deadly pediatric nerve cancer, who would otherwise have no treatment options, according to a new study.
