Worms can evolve to survive intersex populations

(PhysOrg.com) -- Sexually reproducing species need at least two sexes in order to produce offspring, but there are many ways that nature produces different sexes. Many animals (including humans and other mammals) use a chromosomal ...

Ultraviolet protection molecule in plants yields its secrets

Lying around in the sun all day is hazardous not just for humans but also for plants, which have no means of escape. Ultraviolet (UV) radiation from the sun can damage proteins and DNA inside cells, leading to poor growth ...

New type of drug can target all disease-causing proteins

Current drugs block the actions of only about a quarter of known disease-causing proteins, but Yale University researchers have developed a technology capable of not just inhibiting, but destroying every protein it targets.

On guard against drought

Identification of a gene that helps plants to conserve water under drought conditions will bring biologists closer to understanding how plants tolerate drought. Researchers, led by Takashi Kuromori at Japan's RIKEN Plant ...

How do plants rest photosynthetic activity at night?

Photosynthesis, the process by which plants generate food, is a powerful piece of molecular machinery that needs sunlight to run. The proteins involved in photosynthesis need to be 'on' when they have the sunlight they need ...

Scientists discover RNA modifications in some unexpected places

The so-called central dogma of molecular biology—that DNA makes RNA which makes protein—has long provided a simplified explanation for how genetic information is deciphered and translated in living organisms.
