Drivers on cell phones clog traffic
Motorists who talk on cell phones drive slower on the freeway, pass sluggish vehicles less often and take longer to complete their trips, according to a University of Utah study that suggests drivers on cell phones congest traffic.

Scientists find protein potential drug target for treatment-resistant prostate cancer
Scientists at Jefferson’s Kimmel Cancer Center in Philadelphia have found that a signaling protein that is key to prostate cancer cell growth is turned on in nearly all recurrent prostate cancers that are resistant to hormone therapy. If the findings hold up, the protein, called Stat5, may be a specific drug target against an extremely difficult-to-treat cancer.

What Tips The Balance? Understanding Why X Chromosome Inactivation Can Be Skewed
To ensure that women and men express equivalent levels of the genes found on X chromosomes, one of the two X chromosomes in the cells of a women is inactive. X chromosome inactivation (XCI) occurs early in development, at approximately the time an embryo implants in the womb, and all cells stemming from a given cell have the same X chromosome inactivated.

New plant study reveals a 'deeply hidden' layer of the transcriptome
Cells keep a close watch over the transcriptome – the totality of all parts of the genome that are expressed in any given cell at any given time. Researchers at the Salk Institute for Biological Studies and the University of Missouri-Kansas City teamed up to peel back another layer of transcriptional regulation and gain new insight into how genomes work.

The approach is still experimental, but holds promise for millions of women left with cratered areas and breasts that look very different from each other after cancer surgery. It also might be a way to augment healthy breasts without using artificial implants.

That's how 24-year-old Erik Ramsey has spent the last eight years of his life. He suffered a brain stem stroke after a car accident when he was 16, leaving him with "locked-in" syndrome

Profound immune system discovery opens door to halting destruction of lupus
A researcher has discovered an entirely new and powerful molecular switch that controls the inflammatory response of the immune system. The major finding, reported in the December 14th issue of the journal Cell, means that new methods can now be pursued to shut down uncontrolled inflammation, restore immune system regulation, and treat chronic autoimmune disorders such as lupus.

Deadly virus strips away immune system's defensive measures
When the alert goes out that a virus has invaded the body, cells that have yet to be attacked prepare by "armoring" themselves for combat, attaching specific antiviral molecules to many of their own proteins to help resist the invader. Unfortunately, the deadly Crimean Congo hemorrhagic fever virus knows a simple but devastating way around this defense: just cut the armor off host cell proteins.

New chemistry and microsurfaces have led to super oil-repellent materials that are self-cleaning
Researchers have made materials that repel oil and are able to clean themselves without the help of soap and water. What's more, the researchers describe exactly how the materials work, which could help others design similar materials. This could lead to a range of applications, including fingerprint-shedding cell-phone displays.

Heads Or Tails? Scientists Identify Gene That Regulates Polarity In Regenerating Flatworms
When cut, a planarian flatworm can use a population of stem cells called neoblasts to regenerate new heads, new tails or even entire new organisms from a tiny fragment of its body. Mechanisms have been sought to explain this process of regeneration polarity for over 100 years, but until now, little was known about how planaria can regenerate heads and tails at their proper sites.
