Neuronal Feedback Could Change What We "See"
March 30, 2024 9:59 am | by Carnegie Mellon University | News | CommentsEver see something that isn't really there? Could your mind be playing tricks on you? The "tricks" might be your brain reacting to feedback between neurons in different parts of the visual system, according to a new study.
Blood Test for Concussions? Researchers Report Some Progress
March 30, 2024 9:40 am | by Lindsey Tanner, AP Medical Writer | News | CommentsNew research bolsters evidence that a simple blood test may someday be used to detect concussions. It suggests that a protein linked with head trauma may be present in blood up to a week after injury, which could help diagnose patients who delay seeking treatment.
Primary Human Cancer Cells Obtained Directly From Variety of Tumors
March 29, 2024 10:47 am | by AMSBIO | Product Releases | CommentsAMSBIO's extensive range of primary human cancer cells are obtained directly from a variety tumor types, including breast, colon and prostate. Provided with the original pathological diagnoses and analyzed for key mutations, the primary human cancer cells present the real characteristics of their in vivo state, remain heterogeneous for several passages and thus enhance pharmacogenetic and molecular diagnostic testing abilities.
Imaging Predicts Long-term Effects in Veterans with Brain Injury
March 29, 2024 10:41 am | by Radiological Society of North America | News | CommentsDiffusion tensor imaging (DTI), a type of MRI, may be able to predict functional post-deployment outcomes for veterans who sustained mild traumatic brain injury (MTBI), or concussion, during combat, according to a new study.
Researchers Learn How The Bat Got Its Wings
March 29, 2024 10:37 am | by UCSF | News | CommentsAn international team of scientists have for the first time identified genes and gene regulatory elements that are essential in wing development in the Natal long-fingered bat (Miniopterus natalensis), a species widely distributed in eastern and southern Africa.
How Cancer Stem Cells Thrive When Oxygen Is Scarce
March 29, 2024 10:26 am | by Johns Hopkins University | News | CommentsWorking with human breast cancer cells and mice, scientists say new experiments explain how certain cancer stem cells thrive in low oxygen conditions. Proliferation of such cells, which tend to resist chemotherapy and help tumors spread, are considered a major roadblock to successful cancer treatment.
Fluorescent Nanoparticle Tracks Cancer Treatment’s Effectiveness in Hours
March 29, 2024 10:00 am | by Bevin Fletcher, Associate Editor | News | CommentsBioengineers at Brigham and Women’s Hospital have developed a new technique to help determine if chemotherapy is working in as few as eight hours after treatment. The new approach, which can also be used for monitoring the effectiveness of immunotherapy, has shown success in pre-clinical models.
Scientists Develop Blood Test for Tuberculosis
March 29, 2024 9:55 am | by Bevin Fletcher, Associate Editor | News | CommentsAn international team of scientists have developed a blood test, based on biomarkers in gene activity that can reliably predict whether a person with the Mycobacterium tuberculosis bacterium will develop active tuberculosis (TB).

Study Finds Vast Diversity Among Viruses that Infect Bacteria
March 28, 2024 9:54 am | by Washington University in St. Louis | News | CommentsA new study suggests that bacteriophages made of RNA – a close chemical cousin of DNA – likely play a much larger role in shaping the bacterial makeup of worldwide habitats than previously recognized.
Microbe With Stripped-down DNA May Hint at Secrets of Life
March 28, 2024 9:46 am | by Malcolm Ritter, AP Science Writer | News | CommentsScientists have deleted nearly half the genes of a microbe, creating a stripped-down version that still functions, an achievement that might reveal secrets of how life works.
Scientists Pinpoint Brain Circuit for Risk Preference in Rats
March 28, 2024 9:39 am | by Stanford University | News | CommentsInvestigators have identified a small group of nerve cells in a specific brain region of rats whose signaling activity, or lack of it, explains the vast bulk of differences in risk-taking preferences among the animals.
New Class of Molecular 'Lightbulbs' Illuminate MRI
March 28, 2024 9:33 am | by Duke University | News | CommentsResearchers have taken a major step towards realizing a new form of MRI that could record biochemical reactions in the body as they happen.
