A protein that breast, lung and other cancers use to promote their spread – or metastasis – to the brain, has been identified by a team led by Weill Cornell Medicine and NewYork-Presbyterian investigators. The protein, CEMIP, will now be a focus of efforts to predict, prevent and treat brain […]

MIT engineers have shown that they can enhance the performance of drug-delivery nanoparticles by controlling a trait of chemical structures known as chirality — the “handedness” of the structure. Many biological molecules can come in either right-handed or left-handed forms, which are identical in composition but are mirror images of […]

NK cells mean Natural Killer cells. They are part of the innate immune system. They are known primarily for their ability to recognize and kill tumor cells, cells infected by viruses and bacteria, or dying by apoptosis. Although evidence about their antitumoral capacity, how this activity occurred remained unknown. The […]

A blood test that measures the amount of cell-free DNA (cfDNA) in the bloodstream – called a liquid biopsy – correlates with how patients will progress after they are diagnosed with glioblastoma (GBM), the deadliest and most common primary brain tumor in adults. In a new study, researchers from the Abramson […]

There is, in Colombia, a family with a tragic legacy of forgetfulness. “People in this large family get Alzheimer’s like clockwork at age 45-50,” said UC Santa Barbara neuroscientist Kenneth S. Kosik, the campus’s Harriman Professor of Neuroscience and co-director of the Neuroscience Research Institute. Their aggressive, genetic form of the […]

Researchers have found a way to create a super-inhibitor that effectively stops the development of Parkinsons by using the Parkinson disease itself as an active building block. Various neurodegenerative diseases such as Parkinson’s are closely linked to the aggregation of individual components called monomers of a specific protein that forms […]

Inserted in the human genome thousands of years ago, the genes can produce viral proteins without activating the whole virus. Genes from a virus that was stitched into the human genome thousands of years ago are active, producing proteins in the human brain and other tissues, according to researchers at […]

A modified protein in benign-appearing meningiomas can reveal which are truly benign and which are more dangerous and require more aggressive treatment, researchers have discovered. The finding may also offer clues as to why these ‘benign’ tumors, which arise from the membranes that surround the brain and spinal cord, start […]

The checkpoint inhibitor pembrolizumab (Keytruda) increases the survival time of patients with advanced head and neck cancers, according to a new global study led by Yale Cancer Center (YCC). The data was published in the journal The Lancet. The findings of the phase 3 study show that, compared to the standard […]

Sandia scientist pushes technology’s limits to see fundamental feature of stretched S-DNA. An advanced imaging technique reveals new structural details of S-DNA, ladder-like DNA that forms when the molecule experiences extreme tension. This work conducted at Sandia National Laboratories and Vrije University in the Netherlands provides the first experimental evidence […]

Do you know how many people in the world suffer from diabetes? About 422, according to World Health Organization, but we can’t know for certain. The issue here is that many people who are suffering from diabetes live without diagnosis. This is a huge problem, but scientists think that one […]

Researchers reveal structures of skeletal components in hair-like cilia. It’s not every day that scientists get to publish a paper on Halloween about a skeleton, but that’s what the laboratories of Alan Brown in the Blavatnik Institute at Harvard Medical School and Rui Zhang at Washington University in St. Louis just did. As reported […]

Finding a handful of cancer cells hiding among billions of blood cells in a patient sample can be like finding a needle in a haystack. In a new approach enabled by 3D-printed cell traps, researchers are removing the hay to expose the cancer cells. Trapping the white blood cells – […]

Between 2005 and 2015, as the opioid crisis in America came into focus, prescriptions for gabapentinoid medications — gabapentin and pregabalin — to adults with cancer saw a two-fold increase, a University of Michigan Rogel Cancer Center study has found. Gabapentin, which affects voltage-gated calcium channels in the brain, was originally approved […]

The researchers from the Department of Experimental Psychology, the Wellcome Centre for Integrative Neuroimaging (WIN) and the Nuffield Department of Clinical Neurosciences, used an MRI scanner to observe changes in parts of the brain associated with learning and learned experiences while volunteers completed tasks that involved a reward.
