Feed Science Daily: CryoSat launch delayed (

The launch of ESA's CryoSat-2 satellite from the Baikonur Cosmodrome in Kazakhstan, scheduled for 25 February, has been delayed due to a concern related to the second stage steering engine of the Dnepr launcher.

Feed Science Daily: Contrast-enhanced MRI could play a key role in differentiating between common ty (

Contrast-enhanced magnetic resonance imaging may help physicians differentiate between rheumatoid arthritis and psoriatic arthritis in the hand and wrist enabling more targeted therapies unique to each condition, according to a study. Contrast-enhanced MRI uses contrast media to improve the visibility of internal bodily structures.

Feed Science Daily: Personalized blood tests for cancer using whole genome sequencing (

Scientists have used data from the whole genome sequencing of cancer patients to develop individualized blood tests they believe can help physicians tailor patients' treatments. The genome-based blood tests, believed to be the first of their kind, may be used to monitor tumor levels after therapy and determine cancer recurrence.

Feed Science Daily: Potentially deadly infection linked to frequent cow exposure (

A common bacteria found in many healthy adult females that can cause life-threatening infections when passed to newborns could be introduced to some women through frequent contact with cows, according to a new research. Group B streptococcus could be a zoonotic disease -- transmitted between different species -- which may have significant public health implications.

Feed Science Daily: Chemical tags likely to affect metabolism, cancer development (

New research suggests that the addition or removal of a certain type of chemical tag -- called an acetyl group -- onto metabolic enzymes plays a key role in how cellular metabolism is regulated. The finding gives researchers vital clues to understand how normal cells respond to nutrient changes and how the process by which normal cells turn cancerous, and could one day lead to new drugs that starve cancer cells into submission.

Feed Science Daily: Scientists discover how protein trips up germs (

If bad bacteria lurk in your system, chances are they will bump into the immune system's protective cells whose job is gobbling germs. The catch is that these do-gooders, known as macrophages, ingest and destroy only those infectious invaders that they can securely hook and reel in. Now, scientists have shown that a healthy immune response depends on a protein called TRPV2 which, they discovered, is the means by which macrophages capitalize on brief and accidental encounters with nasty bugs.

Feed Science Daily: In learning, the brain forgets things on purpose (

Scientists have known that newly acquired, short-term memories are often fleeting. But a new study in flies suggests that kind of forgetfulness doesn't just happen. Rather, an active process of erasing memories may in some ways be as important as the ability to lay down new memories.

Feed Science Daily: Life's smallest motor, cargo carrier of the cells, moves like a seesaw (

Life's smallest motor -- a protein that shuttles cargo within cells and helps cells divide -- does so by rocking up and down like a seesaw according to new high-resolution snapshots of a protein called kinesin. The result is the closest look yet at the structural changes kinesin proteins undergo as they ferry molecules.
