Timing is key for bacteria surviving antibiotics

For bacteria facing a dose of antibiotics, timing might be the key to evading destruction. In a series of experiments, Princeton researchers found that cells that repaired DNA damaged by antibiotics before resuming growth ...

Researchers create most complete model of complex protein machinery

Environmental conditions, lifestyle choices, chemical exposure, and foodborne and airborne pathogens are among the external factors that can cause disease. In contrast, internal genetic factors can be responsible for the ...

How does plant DNA avoid the ravages of UV radiation?

If the ultraviolet radiation from the sun damages human DNA to cause health problems, does UV radiation also damage plant DNA? The answer is yes, but because plants can't come in from the sun or slather on sunblock, they ...

How are long strands of DNA packed into tiny cells?

Scientists are a step closer to understanding how DNA, the molecules that carry all of our genetic information, is squeezed into every cell in the body. How DNA is "packaged" in cells influences the activity of our genes ...
