Study gives insight into sun-induced DNA damage and cell repair

A team led by a Baylor University researcher has published a breakthrough article that provides a better understanding of the dynamic process by which sunlight-induced DNA damage is recognized by the molecular repair machinery ...

How plant cells neutralize the potential for self-harm

Photosynthesis makes our atmosphere oxygen-rich and forms the bedrock of our food supply. But under changing or stressful environmental conditions, the photosynthetic process can become unbalanced, resulting in an excess ...

CRISPR-based tool maps gene function in human cells

UC San Francisco scientists have used a high-throughput CRISPR-based technique to rapidly map the functions of nearly 500 genes in human cells, many of them never before studied in detail.

Sex obsession a killer for male snakes

An international team of scientists led by the University of Sydney has confirmed a frenzied approach to the mating season is resulting in males ageing faster and dying earlier and in worse condition than their female counterparts, ...

Scientists publish the first RNA interactome of the human nucleus

Studying sequence and function of DNA has been in the focus of life sciences for decades, but now the interest of many researchers has turned to the RNA. Today, many scientists believe that RNA molecules, together with a ...

Space Station worms' research potential is anything but flat

For years, it was assumed the world was flat. Now, we have a laboratory that orbits our big, blue marble. So, it's funny to think of returning to flatness aboard the International Space Station, but this outpost currently ...

Laser pulses reveal DNA repair mechanisms

A new straightforward method enables monitoring the response of nuclear proteins to DNA damage in time and space. The approach is based on nonlinear photoperturbation.

University takes on taste challenge: MREs

A ready-to-eat Army meal can survive a 1,200-foot parachute drop and stay fresh for up to three years - only to go straight into the trash can if it doesn't appeal to a soldier's taste.

DNA damage: The dark side of respiration

(Phys.org) —Adventitious changes in cellular DNA can endanger the whole organism, as they may lead to life-threatening illnesses like cancer. Researchers at LMU now report how byproducts of respiration cause mispairing ...
