Apr. 24, 2015 — 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 ... read more

Apr. 24, 2015 — 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 ... read more

Apr. 23, 2015 — 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 ... read more

Apr. 23, 2015 — 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 ... read more

Apr. 23, 2015 — 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 ... read more

Apr. 23, 2015 — Scientists have evidenced, at the atomic scale, the three-dimensional structure of the complete human ribosome and the detailed interactions that occur within it. These findings open the way to ... read more

Apr. 23, 2015 — An international team of researchers has sequenced the nearly complete genome of two Siberian woolly mammoths -- revealing the most complete picture to date -- including new information about the ... read more

Apr. 22, 2015 — The genome of an important bacteria contains far more 'junk DNA' than scientists expected -- making its genome more closely resemble that of a higher ... read more

Apr. 22, 2015 — The likelihood of being bitten by mosquitoes could be down to our genes, according to a study carried out on ... read more

Toxic Mushroom-Based Drug May Help Battle Colorectal Cancer

Apr. 22, 2015 — For some time, cancer scientists have considered the toxin, alpha-amanatin derived from “death cap” mushrooms, as a possible cancer treatment. However, due to its penchant for causing liver ... read more

Canine Cancer Cell Lines for Research and Drug Development

Apr. 22, 2015 — Analagous to the NCI-60, a new panel of authenticated canine cancer cell lines lets veterinary researchers experiment with known ... read more

Battle in the Gut: Immune Cells Help 'Good Bacteria' Triumph Over 'Bad Bacteria'

Apr. 21, 2015 — The body's immune system may be the keeper of a healthy gut microbiota, report scientists. They found that a binding protein on white blood cells could affect whether or not mice produced a ... read more

Messenger RNA-Associated Protein Drives Multiple Paths in T-Cell Development

Apr. 21, 2015 — A lab studies how splicing occurs in T cells and how it is regulated by multiple proteins. This study describes a cascade of events that may explain changes in gene expression that occur during the ... read more

Apr. 21, 2015 — Proteins and lipids have been assumed to move through cell membranes as 'nano rafts'. This 'raft hypothesis' has now been disproved by scientists. "We should not think of the ... read more

Apr. 21, 2015 — Nerve cells come in very different shapes. Researchers now reveal why, in insects, the cell body is usually located at the end of a separate extension. Using mathematical models, they show that this ... read more

Making Biotechnology Interactive With Games, Remote-Control Labs

Apr. 21, 2015 — What if you could interact with cells like fish in an aquarium? Build your own micro-aquarium for cells? Even perform remote-control experiments in robotic biolabs in the cloud? A research team shows ... read more
