Chilled-out tadpoles defy climate odds

University of Queensland researchers have discovered a previously unknown mechanism that allows tadpoles in cold environments to mitigate the detrimental effects of ultraviolet (UV) radiation.

Increase in forest fires may damage the crucial ozone layer

All particles that reach the atmosphere cause different chemical reactions. Particles come partly from natural sources such as volcanic eruptions and forest fires, and partly from pollution and emissions. Aerosol researcher ...

How a single enzyme unleashes a complex DNA repair process

Our DNA is constantly exposed to damaging factors that can lead to aging and age-related diseases such as cancer. PARP1 is an important enzyme that facilitates the response to DNA damage by attaching chemical groups called ...

DNA damage caused by migrating light energy

Ultraviolet light endangers the integrity of human genetic information and may cause skin cancer. For the first time, researchers at Karlsruhe Institute of Technology (KIT) have demonstrated that DNA damage may also occur ...

Molecular sensor scouts DNA damage and supervises repair

In the time it takes you to read this sentence, every cell in your body suffers some form of DNA damage. Without vigilant repair, cancer would run rampant, and now scientists at the University of Pittsburgh have gotten a ...
