Phys.org / The mechanical ratchet: A new mechanism of cell division
Cell division is an essential process for all life on Earth, yet the exact mechanisms by which cells divide during early embryonic development have remained elusive—particularly for egg-laying species.
Medical Xpress / How a rare genetic variant protects some people from developing blood cancers
Blood cancer is an umbrella term for a variety of diseases that affect the blood, bone marrow and lymphatic system. Like most cancers, the cause is usually mutations in the DNA, which are genetic errors that accumulate as ...
Medical Xpress / Fatigue before cancer treatment linked to adverse events
Fred Hutchinson Cancer Center-led investigators found that higher patient-reported fatigue before cancer treatment aligned with higher odds of severe, life-threatening, and fatal treatment-related toxic effects.
Phys.org / Creating psychedelic-like molecules by shining light on life's basic building blocks
UC Davis researchers have developed a new method that uses light to transform amino acids—the building blocks of proteins—into molecules that are similar in structure to psychedelics and mimic their interaction with the ...
Phys.org / Lunar spacecraft exhaust could obscure clues to origins of life
Over half of the exhaust methane from lunar spacecraft could end up contaminating areas of the moon that might otherwise yield clues about the origins of Earthly life, according to a recent study. The pollution could unfold ...
Medical Xpress / Pharmacists and female pharmacy technicians face higher suicide risk, study shows
A new national study led by researchers from University of California San Diego Skaggs School of Pharmacy and Pharmaceutical Sciences reveals that pharmacists and female pharmacy technicians face a significantly higher risk ...
Phys.org / Synchronizing ultrashort X-ray pulses for attosecond precision
Scientists at the Paul Scherrer Institute PSI have, for the first time, demonstrated a technique that synchronizes ultrashort X-ray pulses at the X-ray free-electron laser SwissFEL. This achievement opens new possibilities ...
Tech Xplore / AI gobbling up memory chips essential to gadget makers
As devices from toys to cars get smarter at the Consumer Electronics Show, gadget makers are grappling with a shortage of memory needed for them to work.
Medical Xpress / Study links low lycopene intake to higher risk of severe gum disease in older adults
A new study has found that insufficient dietary lycopene intake is associated with a significantly higher risk of severe periodontitis among U.S. adults ages 65 to 79, with differences in risk patterns observed across race ...
Phys.org / Boosting the cell's own cleanup: New class of small molecules accelerate natural protein degradation
Cells have a remarkable housekeeping system: Proteins that are no longer needed, defective, or potentially harmful are labeled with a molecular "tag" and dismantled in the cellular recycling machinery. This process, known ...
Phys.org / Earth's early sponges were soft: Scientists close fossil record gap
Sponges are among Earth's most ancient animals, but exactly when they evolved has long puzzled scientists. Genetic information from living sponges, as well as chemical signals from ancient rocks, suggest that sponges evolved ...
Medical Xpress / How neuron groups team up to embed memories in context
Humans have the remarkable ability to remember the same person or object in completely different situations. We can easily distinguish between dinner with a friend and a business meeting with the same friend. "We already ...
