Mental Miscues
February 2, 2024 10:13 am | by Carnegie Mellon University | News | CommentsA study investigated the brain’s neural activity during learned behavior and found that the brain makes mistakes because it applies incorrect inner beliefs, or internal models, about how the world works.
Cancer Cells Travel Together to Forge ‘Successful’ Metastases
February 2, 2024 10:05 am | by Johns Hopkins University | News | CommentsThere’s apparently safety in numbers, even for cancer cells. New research in mice suggests that cancer cells rarely form metastatic tumors on their own, preferring to travel in groups since collaboration seems to increase their collective chances of survival, according to researchers.
How, Not Why, the Human Brain Folds
February 2, 2024 10:00 am | by Harvard University | News | CommentsResearchers have shown that while many molecular processes are important in determining cellular events, what ultimately causes the brain to fold is a simple mechanical instability associated with buckling.
Better Cystic Fibrosis Test Invented
February 2, 2024 9:50 am | by Stanford University | News | CommentsResearchers have developed a fast, inexpensive and highly accurate test to screen newborns for cystic fibrosis. The new method detects virtually all mutations in the CF gene, preventing missed diagnoses that delay babies’ ability to begin receiving essential treatment.
Curing Disease by Repairing Faulty Genes
February 2, 2024 9:30 am | by Anne Trafton, MIT News Office | News | CommentsResearchers have now developed a way to deliver the CRISPR genome repair components more efficiently than previously possible, and they also believe it may be safer for human use. In a study of mice, they found that they could correct the mutated gene that causes a rare liver disorder, in 6 percent of liver cells — enough to cure the mice of the disease, known as tyrosinemia.
WHO Declares Global Emergency Over Zika Virus Spread
February 2, 2024 9:10 am | by Jamey Keaten and Maria Cheng, Associated Press | News | CommentsThe World Health Organization declared a global emergency over the explosive spread of the Zika virus, which has been linked to birth defects in the Americas, calling it an "extraordinary event" that poses a public health threat to other parts of the world.
Walgreens Won’t Send Tests to Theranos Lab in California
February 2, 2024 8:58 am | by Bevin Fletcher, Associate Editor | News | CommentsWalgreens will no longer have its tests for customers performed at healthcare startup Theranos’s Newark, Calif., laboratory after the Centers for Medicare & Medicaid Services (CMS) reported violations of a number of clinical policies.
Desiccator Cabinets
February 1, 2024 10:05 am | Product Releases | CommentsNew from Terra Universal are their IsoDry Desiccators cabinets, designed to increase efficiency of low relative-humidity storage. This patent-pending design features a gas dilution module that automatically mixes internal air with nitrogen, or other process gas, to reach the programmed set-point.
Scientists Discover Stem Cells Capable of Repairing Skull, Face Bones
February 1, 2024 10:02 am | by University of Rochester | News | CommentsA team of scientists has, for the first time, identified and isolated a stem cell population capable of skull formation and craniofacial bone repair in mice--achieving an important step toward using stem cells for bone reconstruction of the face and head in the future, according to a new paper.
Free Raptor Protein Found to Prevent Fatty Liver
February 1, 2024 9:59 am | by Columbia University | News | CommentsNon-alcoholic fatty liver disease (NAFLD) is now the most common chronic liver disease, and the fastest-growing reason for liver transplantation. It is estimated that more than half of patients with type 2 diabetes (T2D) have NAFLD, and even patients with type 1 diabetes have higher risk of developing fatty liver than people without diabetes.
Higher Fitness Linked to Reduced Risk of Death After First Heart Attack
February 1, 2024 9:51 am | by Johns Hopkins University | News | CommentsResearchers report evidence that higher levels of physical fitness may not only reduce risk of heart attacks and death from all causes, but also possibly improve the chances of survival after a first attack.
'BPA-free' Plastic Accelerates Embryonic Development, Disrupts Reproductive System
February 1, 2024 9:44 am | by UCLA | News | CommentsCompanies advertise "BPA-free" as a safer version of plastic products ranging from water bottles to sippy cups to toys. Yet new research demonstrates that BPS (Bisphenol S), a common replacement for BPA, speeds up embryonic development and disrupts the reproductive system.
Mapping Regulatory Elements
February 1, 2024 9:37 am | by Larry Hardesty, MIT News Office | News | CommentsResearchers describe a new technique for systematically but efficiently searching long stretches of the genome for regulatory elements. And in their first application of the technique, they find evidence that current thinking about gene regulation is incomplete.
