Collaborative Cancer Research UK-funded studies from University of Oxford researchers have uncovered a new mechanism by which cancer cells adapt to the stresses they encounter as they grow and respond to therapies. This mechanism involves cells releasing small vesicles, known as exosomes. These contain complex mixtures of proteins, RNAs and other molecules, which can re-programme surrounding cells. Exosomes are thought to be released by all cells within the body, and play important roles in many processes in healthy individuals such as immunity and reproduction.
Antibiotic resistance is an increasing battle for scientists to overcome, as more antimicrobials are urgently needed to treat biofilm-associated infections. However scientists from the School of Life Sciences at the University of Warwick say research into natural antimicrobials could provide candidates to fill the antibiotic discovery gap.
Companies seeking to commercialize seafood products made from the cells of fish or shellfish should use the term "cell-based" on product labels, according to a Rutgers study - the first of its kind - in the Journal of Food Science.
Both the U.S. Food and Drug Administration and U.S. Department of Agriculture require food products to have a "common or usual name" on their labels so consumers can make informed choices about what they're purchasing.
Madagascar is a biodiversity hotspot. In the last 20 years new lemur species have been discovered while forested habitats have been quickly disappearing. Recent reports by the IUCN (International Union for the Conservation of Nature) have identified the lemurs as one of the most threated groups of vertebrates, with 33 of the 107 recognized species being critically endangered.
Blood platelet counts at the higher end of normal suggest a high risk of cancer in men aged 60 or over, and should be investigated, according to new University of Exeter research.
Research from the Sidney Kimmel Cancer Center - Jefferson Health (SKCC) found significant decreases nationwide in the number of patients being seen for cancer-related care as the COVID-19 pandemic progressed during the few first months of 2020. The most significant decline was seen in encounters related to new cancer incidences, which included screening, initial diagnosis, second opinion, and treatment initiation appointments.
Irvine, CA - July 27, 2020 - In a new study, researchers found that night- versus day-biting species of mosquitoes are behaviorally attracted and repelled by different colors of light at different times of day. Mosquitoes are among major disease vectors impacting humans and animals around the world and the findings have important implications for using light to control them.
Tiny finger-like projections called filopodia drive invasive behavior in a rare subset of lung cancer cells, researchers at Winship Cancer Institute of Emory University have found.
Adam Marcus' lab has developed innovative techniques for separating "leaders" and "followers," subpopulations of tumor cells that cooperate during the process of metastasis. The lab's new analysis of what molecular features distinguish leader from follower lung cancer cells focuses on filopodia. The results are published in Science Advances.
HOUSTON - (July 27, 2020) - Materials scientists at Rice University and the University of Pennsylvania are calling for a collective, global effort to fast-track the mass production of 2D materials like graphene and molybdenum disulfide.
In a perspective article published online in Materials Today, journal editor-in-chief Jun Lou and colleagues make a case for a focused, collective effort to address the research challenges that could clear the way for large-scale mass production of 2D materials.
Scientists at Tokyo Institute of Technology (Tokyo Tech) and Yokohama National University (YNU) uncover the peculiar mechanism by which spin perturbations travel through a seemingly unpassable region of a quantum spin liquid system. This new insight may represent another building block in next-generation electronics and even quantum computers.
Death Valley doesn't seem like the most ideal place to ride out rising temperatures amid a changing climate. But for the desert plants that live there, it's home--and they face the choice to adapt or die.
By tuning into a subset of brain waves, University of Michigan researchers have dramatically reduced the power requirements of neural interfaces while improving their accuracy--a discovery that could lead to long-lasting brain implants that can both treat neurological diseases and enable mind-controlled prosthetics and machines.
The team, led by Cynthia Chestek, associate professor of biomedical engineering and core faculty at the Robotics Institute, estimated a 90% drop in power consumption of neural interfaces by utilizing their approach.
What The Study Did: Changes over 25 years in how common spanking of children was by parents in the United States are examined in this study.

Graphene, an atomically thin hexagonal structure of carbon atoms is a potential candidate for electronic and optoelectrical applications such as transparent electrodes and interconnect for integrated circuits. Yet, it is one thing to possess such useful properties and to induce an intended characteristic from this "wonder material" is another.
Topology, which is a branch of mathematics, is rising as a universal notion in physics, from condensed matter physics to classical wave systems. Topology has been received particularly warmly in photonics and has spawned a new field called topological photonics. Over the past decade, topological photonics has undergone surprisingly rapid development. Researchers in topological photonics have realized physical phenomena that have only been predicted so far in other fields and have even discovered new phenomena for the first time ever.
