MIT biologist relishes the challenge of picking apart the cell's most complex structure
One of the most important structures in a cell is the nuclear pore complex — a tiny yet complicated channel through which information flows in and out of the cell’s nucleus, directing all other cell ...

How one strain of MRSA becomes resistant to last-line antibiotic
Researchers have uncovered what makes one particular strain of methicillin-resistant Staphylococcus aureus (MRSA) so proficient at picking up resistance genes, such as the one that makes it resistant to vancomycin, the last ...

Mechanical properties of stem cells can foretell what they will become
To become better healers, tissue engineering need a timely and reliable way to obtain enough raw materials: cells that either already are or can become the tissue they need to build. In a new study, Brown ...

Bacteria alive (more or less) in 86-million-year-old seabed clay
(Phys.org) -- A new study by scientists from Denmark and Germany has found live bacteria trapped in red clay deposited on the ocean floor some 86 million years ago. The bacteria use miniscule amounts of oxygen ...

Zooming in on bacterial weapons in 3-D
The plague, bacterial dysentery, and cholera have one thing in common: These dangerous diseases are caused by bacteria which infect their host using a sophisticated injection apparatus. Through needle-like ...

Garlic constituent blocks biofilm formation, could benefit CF patients and others
E Pluribus Unum, the motto of the United States, could just as well apply to biofilm-forming bacteria. Bacterial biofilms are far more resistant than individual bacteria to the armories of antibiotics we have devised to combat ...

How environmental effects regulate genes
Swiss researchers provide evidence that a protein in the cell nucleus responds to environmental stimuli like a kind of sensor, regulates genes accordingly and thus exchanges information with the cell memory. ...

New technique reveals unseen information in DNA code
Imagine reading an entire book, but then realizing that your glasses did not allow you to distinguish "g" from "q." What details did you miss? Geneticists faced a similar problem with the recent discovery ...

Mixed bacterial communities evolve to share resources, not compete
New research shows how bacteria evolve to increase ecosystem functioning by recycling each other's waste. The study provides some of the first evidence for how interactions between species shape evolution when there is a ...
