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 ...
Medical Xpress / Protein unties tangled DNA linked to hotspots of cancer mutations
New research published in Nature Communications has linked a normal cellular process to an accumulation of DNA mutations in cancer and identified cancer-driving mutations in an underexplored part of the genome.
Medical Xpress / Ancient genetics and modern pollutants could provide a clue to endometriosis risk
A new study suggests that certain genetic differences, passed down from ancient human ancestors, and exposure to common present-day chemicals could explain why some women are more likely to develop endometriosis.
Medical Xpress / Childhood instability accelerates women's sexual strategies, study suggests
California State University, Sacramento, researchers traced how disordered childhood social worlds in women connected to faster life history traits and greater mating effort, with those traits explaining 22.2% of the association ...
Phys.org / Sugars, 'gum,' stardust found in NASA's asteroid Bennu samples
The asteroid Bennu continues to provide new clues to scientists' biggest questions about the formation of the early solar system and the origins of life. As part of the ongoing study of pristine samples delivered to Earth ...
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 ...
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 / Why the Amazon's ability to make its own rain matters more than ever
Dr. Magali Nehemy stood on the banks of the Tapajós River in the Amazon rainforest when the community's chief—a man in his seventies who had lived there his whole life—looked out over the bare shoreline and shook his ...
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 / 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 / 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 ...
Tech Xplore / What's the best way to expand the US electricity grid? Study illuminates choices about reliability, cost and emissions
Growing energy demand means the U.S. will almost certainly have to expand its electricity grid in coming years. What's the best way to do this? A new study by MIT researchers examines legislation introduced in Congress and ...
