Scientists discover small RNA that regulates bacterial infection

People with weakened immune systems are at constant risk of infection. Pseudomonas aeruginosa, a common environmental bacterium, can colonize different body parts, such as the lungs, leading to persistent, chronic infections ...

Mediterranean diet's cellular effects revealed

People who follow the Mediterranean diet—rich in fats from olive oil and nuts—tend to live longer, healthier lives than others who chow down primarily on fast food, meat and dairy. But it hasn't been clear on a cellular ...

Studying epigenetic regulation at the single-molecule level

If one imagines the genome as an instruction manual for the functioning of a cell, every page of this manual is covered with annotations, highlights, and bookmarks. The role of some of these marks remains mysterious—do ...

New tool for early detection of hypertension

Russian scientists have come up with a new tool for early detection of hypertension. They applied surface-enhanced Raman spectroscopy powered by silver nanoparticles to detect hypertension-induced molecular changes in blood ...

How plants' threat-detection mechanisms raise the alarm

New work led by Carnegie's Zhiyong Wang untangles a complex cellular signaling process that underpins plants' ability to balance expending energy on growth and defending themselves from pathogens. These findings, published ...

Ocean life may adapt to climate change, but with hidden costs

Suppose that we could watch twenty generations of whales or sharks adapting to climate change—measuring how they evolve and how their biology changes as temperatures and carbon dioxide levels rise. That could tell us a ...
