Medical Xpress / Turning brain neurons on and off with light: A reversible synaptic switch
A research team led by Professor Ji Won Um of the Center for Synapse Diversity and Specificity, Department of Brain Sciences, DGIST, in collaboration with a team led by Professor Alice Ting at Stanford University, has developed ...
Phys.org / Greenwashing firms are scrutinized less if they are in politicians' pockets, study finds
Companies with strong political connections are more likely to escape scrutiny over greenwashing, according to new research from Durham University Business School. Greenwashing occurs when organizations overstate or misrepresent ...
Medical Xpress / In Crohn's disease and ulcerative colitis, inflammation blocks its own healing
Why does inflammation persist in Crohn's disease and ulcerative colitis, even as the body is trying to bring it under control? Researchers in Kiel and the United States have identified a mechanism that offers a surprising ...
Medical Xpress / Supercentenarians have an abundance of cancer-killing immune cells
The human immune system has specialized cells called CD4 cytotoxic T lymphocytes (CD4 CTLs), which have been shown to kill tumor cells in some cancers. When a person gets sick, these cells multiply in a process called clonal ...
Phys.org / Search in strange quark sector reveals new particle possibilities
Despite science's best efforts to classify the vast menagerie of subatomic particles discovered over the past few decades, some exotic varieties defy explanation. Now, nuclear physicists at the U.S. Department of Energy's ...
Phys.org / Light-driven proteins in artificial membranes—a new method for biohybrid systems
Light-driven membrane proteins are key components in biohybrid systems because they can convert light energy into ion gradients, enabling energy conversion or sensory applications. While their integration into natural lipid ...
Tech Xplore / Inexpensive reflective tiles pave the way for millimeter wave wireless communications
Unlike Wi-Fi or cellular signals, millimeter-wave wireless communication channels are unable to pass through walls, furniture or other objects. This reality is part of what is holding back the implementation of millimeter-wave ...
Phys.org / Fastest known Milky Way star offers new test of supermassive black hole's spin
Astronomers have discovered the fastest known star in our galaxy, the Milky Way, orbiting the black hole at its center. The star, named S301, was detected with the European Southern Observatory's Very Large Telescope Interferometer ...
Phys.org / Jellyfish reveal how rapid cell turnover may suppress early cancer growth
Although increased cell proliferation is a hallmark of cancerous tissues, in some cases it may actually protect against tumor growth, according to a new study by Caltech researchers. Using mathematical models, the work suggests ...
Medical Xpress / For students, consistent exercise may matter more for mental health than intense workouts
Infrequent exercise is associated with a higher prevalence of common mental disorders such as depression and anxiety among higher education students in Norway, according to a study published in PLOS ONE by Michael Grasdalsmoen ...
Medical Xpress / World's largest psilocybin brain-imaging study maps how context reshapes psychedelic effects
A landmark five-year study by Monash University has found psychedelics reorganize brain patterns, giving clinicians powerful new insights into their therapeutic potential.
Phys.org / A 100-year-old mystery in the cat kidney may be linked to scent communication
Many animals obtain information about others from scent marks left in the environment, including urine. Because these marks remain after the sender has left, they allow animals to communicate across space and time. But odor ...
