Phys.org / How plants balance woody xylem and fleshy tissues: Thermospermine targets methylated ribosomes
Scientists have identified a crucial mechanism that allows plants to shape their vascular systems, determining whether they grow soft edible storage organs or develop the rigid woody tissue characteristic of trees. Published ...
Medical Xpress / Cancer cell study sheds light on cachexia's origins
New research from the University of Oklahoma, published today in Cancer Cell, describes for the first time a "triangle regulation theory" of cancer-induced cachexia and anorexia. Cachexia is a muscle-wasting and fat-loss ...
Phys.org / mRNA fragments reveal a hidden process that protects cells from harmful mutations
Some genetic mutations that are expected to completely stop a gene from working surprisingly cause only mild or even no symptoms. Researchers in previous studies have discovered one reason why: cells can ramp up the activity ...
Phys.org / A little protein with a big role in building Earth's carbon fixing machinery
An international team of scientists has discovered that a small, low-abundance protein plays a surprisingly big role in assembling carboxysomes—specialized bacterial microcompartments that enable efficient carbon fixation ...
Phys.org / Scientists uncover Iron Age origins of Vietnamese tooth blackening practices
Not everyone wants their teeth to be white and gleaming. Tooth blackening is a recognized part of modern Vietnamese culture, and a recent discovery hints that the roots of this practice may stretch all the way back to the ...
Phys.org / Exploring how the Gulf Stream affects the climate system and the carbon cycle
It is well documented that the Gulf Stream plays a pivotal role in the climate system through its transfer of heat, which ultimately supplies warmth to northern latitudes in the North Atlantic. What remains less well understood ...
Phys.org / Major earthquakes are just as random as smaller ones
For obvious reasons, it would be useful to predict when an earthquake is going to occur. It has long been suspected that large quakes in the Himalayas follow a fairly predictable cycle, but nature, as it turns out, is not ...
Phys.org / A DNA 'on-off' switch? Light and redox cues reversibly link strands for nanotech
DNA, the blueprint of life, is best known for its fundamental role as genetic material—storing and transmitting biological information through the precise sequence of its bases. For decades, this information-storage function ...
Medical Xpress / Researchers identify promising Alzheimer's disease drug target
Indiana University School of Medicine scientists have identified a promising drug target for Alzheimer's disease. The team found that removing an enzyme from neurons in the brain substantially reduces amyloid plaques—a ...
Medical Xpress / Commonly used drugs could help prevent delirium after surgery
A new study has found that several commonly used drugs could significantly reduce the risk of delirium in older people following surgery. Delirium—a sudden state of confusion and memory problems—affects around one in ...
Medical Xpress / What to know about common Winter Olympics injuries
As the world collectively watches the 2026 Winter Olympics, we are in awe of athletes making their intense sports look graceful and natural. What we do not see behind the scenes are the countless hours of training to compete ...
Medical Xpress / Best diagnostic test for ovarian cancer in premenopausal women identified
Premenopausal women would benefit from a significantly more accurate diagnostic pathway for ovarian cancer, as a new study finds that an advanced ultrasound test, IOTA ADNEX, identified 9 out of 10 cancers in women who took ...
