PHILADELPHIA -- (Sept. 19, 2017) -- In a multi-institutional collaborative study, scientists at The Wistar Institute and the Medical University of Vienna, Austria, have identified the role of tumor-infiltrating or tumor-associated B-cells ("TABs") in melanoma progression and resistance to targeted therapy. This study provides a molecular mechanism that governs the cross-talk between TABs and tumor cells as well as a potential new therapeutic strategy for combating tumors resistant to treatment. The study was published online in Nature Communications.
WASHINGTON, D.C., September 19, 2017 -- The beautiful sound of birdsongs emerging from the trees is a wonderful example of how much nature can still teach us, even as much about their origins are still mysterious to us. About 40 percent of bird species learn to vocalize when they are exposed to a tutor, a behavior of interest to many neurologists and neurobiologists. The other 60 percent can vocalize instinctually in isolation. The variety across species, and the relationship between the nervous system and biomechanics makes birdsong production a complex process to unravel and understand.
WASHINGTON, D.C., Sept. 19, 2017 - Fluorescence microscopy gives researchers incredible power to illuminate the tiniest structures and capture the real-time activities of live cells by tagging biological molecules with a veritable rainbow of fluorescent dyes. This power comes at a cost: The technology can be expensive and time-consuming and, so far, has resisted attempts at automation.
Progress on the way to smart nanomachines: Chemists of Ludwig-Maximilians-Universitaet (LMU) in Munich have modified the synthesis of a molecular motor so as to reduce the speed of its light-driven rotation, thus permitting the researchers to analyze the mechanism of motion in complete detail.
CARVER, Mass., September 19, 2017 - A thorough review of dozens of studies led scientists to conclude that healthcare professionals should be telling their patients to have cranberry products as a first step in reducing recurrent UTIs. The comprehensive meta-analysis and assessment of human clinical trials, published in the official journal of the American Urological Association, The Journal of Urology®, assures practitioners and their patients that cranberry products are a low cost, low risk and effective way to help prevent recurrent UTIs.1
How does a driver's brain realize that a stop sign is behind a bush when only a red edge is showing? Or how can a monkey suspect that the yellow sliver in the leaves is a round piece of fruit?
The human (and non-human) primate brain is remarkable in recognizing objects when the view is nearly blocked. This skill let our ancient ancestors find food and avoid danger. It continues to be critical to making sense of our surroundings.
New York, NY -- Sept. 19, 2017-- Researchers at Columbia Engineering have solved a long-standing issue in the creation of untethered soft robots whose actions and movements can help mimic natural biological systems. A group in the Creative Machines lab led by Hod Lipson, professor of mechanical engineering, has developed a 3D-printable synthetic soft muscle, a one-of-a-kind artificial active tissue with intrinsic expansion ability that does not require an external compressor or high voltage equipment as previous muscles required.
HOUSTON -- Immune-cell based therapies opening a new frontier for cancer treatment carry unique, potentially lethal side effects that provide a new challenge for oncologists, one addressed by a team led by clinicians at The University of Texas MD Anderson Cancer Center with proposed guidelines for systematically dealing with the toxicities of these drugs.
Scarce metals are found in a wide range of everyday objects around us. They are complicated to extract, difficult to recycle and so rare that several of them have become "conflict minerals" which can promote conflicts and oppression. A survey at Chalmers University of Technology now shows that there are potential technology-based solutions that can replace many of the metals with carbon nanomaterials, such as graphene.
BINGHAMTON, NY - A new paper-based sensor patch developed by researchers at Binghamton University, State University of New York could allow diabetics to effectively measure glucose levels during exercise.
Today's most widespread methods for glucose self-testing involve monitoring glucose levels in blood. Conventional measurements, however, are not suitable for preventing hypoglycemia during exercise, said Binghamton University Electrical and Computer Science Assistant Professor Seokheun Choi.
