Trial pitches MGB-BP-3 against clostridium difficile
Scientists at the University of Strathclyde in Glasgow have been working to identify compounds with important anti-infective activity and suitable for treating serious infectious diseases caused by bacteria and parasites, such as Clostridium difficile. Their work has led to the creation of the new drug known as MGB-BP-3 (MGB = minor groove binder). Report: Mark Nicholls

Timing is everything in cells
Everyone who has played in a band or orchestra knows that playing in time creates music, while playing out of time creates cacophony. In an orchestra, each player may be out of tune when warming up, but eventually, all players must reach the same pitch, rhythm, and timing to produce a viable piece of music.

Subpopulation of white blood cells stands guard
One goal of immunotherapy is to rally a patient’s often over-burdened immune cells to effectively attack a tumor. Among foot soldiers on the immune front line is a subpopulation of white blood cells called “patrolling monocytes,” whose job is to cruise the bloodstream, cart off cellular debris, and block invasion of a less benign population of inflammatory cells.

X-Citing X Chromosome
A team of scientists from the University of Michigan Medical School shows that the genetic material in female (but not male) cells makes tiny amounts of a special genetic material called RNA to make one of the two X chromosomes silent. They call this RNA XistAR.

New way of doing ‘lab on a chip’ medical diagnostics?
Northwestern University scientists have developed the first liquid nanoscale laser. And it’s tunable in real time, meaning you can quickly and simply produce different colors, a unique and useful feature. The laser technology could lead to practical applications, such as a new form of a “lab on a chip” for medical diagnostics.

'Smart bandage' detects bed sores
Engineers at the University of California, Berkeley, are developing a new type of bandage. Thanks to advances in flexible electronics, the researchers have created a new "smart bandage" that uses electrical currents to detect early tissue damage from pressure ulcers, or bedsores, before they can be seen by human eyes - and while recovery is still possible.

Blame your health problems on your grandfather
If you have diabetes, or cancer or even heart problems, maybe you should blame it on your dad’s behaviour or environment. Or even your grandfather’s. That’s because, in recent years, scientists have shown that, before his offspring are even conceived, a father’s life experiences involving food, drugs, exposure to toxic products and even stress can affect the development and health not…

How the brain decides blame and punishment
Juries in criminal cases typically decide if someone is guilty, then a judge determines a suitable level of punishment. New research confirms that these two separate assessments of guilt and punishment – though related - are calculated in different parts of the brain. In fact, researchers found that they can disrupt and change one decision without affecting the other.
