Diabetes drug found in freshwater is a potential cause of intersex fish
A medication commonly taken for Type II diabetes, which is being found in freshwater systems worldwide, has been shown to cause intersex in fish – male fish that produce eggs. The medication is found to be widespread in freshwater.

Beyond genes: Are centrioles carriers of biological information?
Scientists have discover that certain cell structures, the centrioles, could act as information carriers throughout cell generations. The discovery raises the possibility that transmission of biological information could involve more than just genes. Centrioles may actually be carriers of information, which holds profound implications for biology and disease treatment.

Discovery of a protein capable of regulating DNA repair during sperm formation
Researchers have discovered that the signalling route - a cascade activation of several molecules - triggered by the ATM protein regulates DNA repair during the production of spermatocytes by meiosis, the cell division process which yields spermatozoa.

Researchers add a new wrinkle to cell culture
Using a technique that introduces tiny wrinkles into sheets of graphene, researchers have developed new textured surfaces for culturing cells in the lab that better mimic the complex surroundings in which cells grow in the body.

Finding new life for first-line antibiotics
Researchers have identified a single, simple measure -- recovery time -- to guide antibiotic dosing that could bring an entire arsenal of first-line antibiotics back into the fight against drug-resistant pathogens.

A GPS for chromosomes: Microtubules direct chromosomes during cell division
Scientists have identified a " Highway Code" within cells, a finding that changes the way we perceive how chromosomes move during cell division. Using chromosomes as a model to explain this navigation system, the research team show how this signaling mechanism determines the path through which molecular transporters travel. They have revealed that the existence of specific signals on microtubules -- which work as intracellular highways -- give directions to chromosomes on which route to take in the course of cell division.

Human tape worm drug shows promise against MRSA in lab
A drug already approved to fight tapeworms in people, effectively treated MRSA superbugs in lab cultures and in infected nematode worms. The scientists are pursuing further testing with hope that the findings will lead to new treatments for deadly MRSA infections.

Looking to fossils to predict tooth evolution in rodents: Ever-growing molars in the future?
Fifty million years ago, all rodents had short, stubby molars -- teeth similar to those found in the back of the human mouth, used for grinding food. Over time, rodent teeth progressively evolved to become taller, and some rodent species even evolved continuously growing molar teeth. A new study predicts that most rodent species will have ever-growing molars in the far distant future.

Thawing permafrost feeds climate change
Single-cell organisms called microbes are rapidly devouring the ancient carbon being released from thawing permafrost soil and ultimately releasing it back into the atmosphere as carbon dioxide, according to new research. Increased carbon dioxide levels, of course, cause the Earth to warm and accelerate thawing.
