Medical Xpress / Molecular switch links early-life stimulation to lasting memory changes
Researchers have identified a molecular mechanism that helps explain why growing up in a stimulating environment enhances memory. In contrast, a lack of stimulation can impair it. The team from the Institute for Neurosciences ...
Phys.org / New molecular view of cholera 'tail' could inform better treatment
Cholera is a deadly bacterial disease that kills about 95,000 people every year. Vibrio cholerae bacteria infect cells in the small intestine, which the bacteria can do in part due to their flagella—powerful tail-like structures ...
Phys.org / Seeing inside smart gels: Scientists capture dynamic behavior under stress
Advances in materials science have led to the development of "smart materials," whose properties do not remain static but change in response to external stimuli. One such material is poly(N-isopropylacrylamide), or PNIPAM, ...
Phys.org / The inequalities of laundry: Research reveals overlooked source of microplastic pollution
Researchers at University of Toronto Engineering have observed that handwashing synthetic fabrics in water with higher total dissolved solids (TDS) leads to more microplastic fibers (MPF) being released, creating implications ...
Phys.org / Chance discovery converts toxic nitric oxide into nitrogen gas at room temperature
Nitrogen is a crucial component of proteins and nucleic acids, the fundamental building blocks of all living things, and thus is essential to life on Earth. Gaseous N2 from the atmosphere can be fixed by soil bacteria capable ...
Medical Xpress / Backup DNA repair system could be cancer's weak spot
The DNA inside our cells is constantly being damaged, and one of the worst kinds of damage is a double-strand break—when both sides of the DNA helix are cut at once. Healthy cells can normally fix these breaks using highly ...
Phys.org / Sunlight, water and air power a cleaner method for making hydrogen peroxide
Cornell scientists have discovered a potentially transformative approach to manufacturing one of the world's most widely used chemicals—hydrogen peroxide—using nothing more than sunlight, water and air. The research is ...
Phys.org / Astronomers warn satellite growth may contaminate nearly all space telescope data
Light from the half a million satellites that humanity is planning to launch into Earth's orbit in the coming years could contaminate almost all the images taken by space telescopes, NASA astronomers warned Wednesday.
Medical Xpress / KRAS-mutant cancers: Potential target could overcome treatment resistance
Researchers at The University of Texas MD Anderson Cancer Center have identified a specific protein, RASH3D19, that is responsible for activation of RAS signaling pathways involved in aggressive tumor growth and resistance ...
Phys.org / Common aldehydes transformed by light could accelerate drug discovery and material development
A new chemical method that could speed up the creation of medicines, materials and products people rely on every day has been developed by University of Hawaiʻi at Mānoa Department of Chemistry researchers. The work, published ...
Phys.org / Self-adapting fiber component tackles heat challenges in high-power fiber lasers
Thulium fiber lasers, operating at a wavelength of 2 micrometers, are valued for applications in medicine, materials processing, and defense. Their longer wavelength makes stray light less damaging compared to the more common ...
Phys.org / C-Compass: AI-based software maps proteins and lipids within cells
A new tool developed by Helmholtz Munich and the German Center for Diabetes Research and the University of Bonn makes spatial proteomics and lipidomics easier to use—no coding required. C-COMPASS allows scientists to profile ...
