Phys.org / The way a cell fails to divide after copying its DNA can determine its fate
Cell division is one of the most fundamental and complex processes underpinning life. In human cells, thousands of molecules coordinate with one another in highly precise steps, all within a fraction of a second. But things ...
Phys.org / How photosynthetic bacteria pass light along: Two major energy pathways identified
RIKEN researchers have found out how light energy harvested by pigments besides chlorophyll is transferred to the molecular site where photosynthesis occurs in cyanobacteria. The work is published in the journal Plant and ...
Phys.org / Invisible fertility crisis: Chemicals and climate change threaten reproduction across species
The rise in infertility is not limited to humans, as environmental stressors are quietly undermining the reproductive potential of different forms of life. A recent review published in npj Emerging Contaminants investigated ...
Tech Xplore / Portable detector spots GPS spoofing in real time, even on move
In a world where cell phones and cars guide us everywhere, we've come to trust global positioning as much as we trust our own senses. What happens when that trust is broken?
Medical Xpress / FDA approves once-daily Idvynso tablet for treating HIV
The U.S. Food and Drug Administration has approved Merck's Idvynso (doravirine/islatravir), a new, once-daily, two-drug single tablet for the treatment of HIV-1 infection in adults to replace the current antiretroviral regimen ...
Medical Xpress / Blood test shows promise for detecting testicular cancer when standard markers miss
Mayo Clinic researchers have developed a blood-based method that may help detect germ cell tumors, the most common type of testicular cancer, including cases that do not show up on standard blood tests, according to a study ...
Medical Xpress / A routine virus can slow breast cancer spread to the lungs, offering hidden protective power
Respiratory syncytial virus (RSV), mostly infects the lungs, nose, throat, and respiratory tract, and can cause illness ranging from mild cold and fever-like symptoms to severe pneumonia and bronchitis. A recent study has ...
Medical Xpress / Study urges alcohol drinkers to be aware of emotional state
While, historically, men in the United States have tended to drink more than women, that trend has reversed over the last decade, prompting a University of Rhode Island behavioral science psychology student to study the implications ...
Phys.org / Mechanochemistry simplifies synthesis of challenging conductive organic molecules
Mechanochemistry is a growing field for chemical reactions that proceed in the solid state in the absence, or with minuscule amounts, of solvent added. For decades, solvents have been considered conventional for the progression ...
Medical Xpress / One of the world's most common knee surgeries does not help and may even be harmful
Partial meniscectomy does not improve patient symptoms or function, reveals a 10-year follow-up of the FIDELITY, a placebo-surgery controlled trial published in the New England Journal of Medicine.
Phys.org / ALMA reveals giant molecular clouds across Needle galaxy's full disk
An international team of astronomers has employed the Atacama Large Millimeter/submillimeter Array (ALMA) to perform high-resolution observations of the Needle galaxy. Results of the new observational campaign, presented ...
Medical Xpress / Turning immune cells into tumor allies: A cancer cell protein can reprogram frontline defenders
Cancer cells can disarm the immune system not just by hiding from it, but by actively reprogramming nearby immune cells into a suppressed state. This previously unrecognized molecular interaction, discovered by scientists ...
