Previously poorly investigated signalling pathway is critical for proliferation of cancer cells

06-02-2013

A previously poorly investigated signalling pathway is crucial for the growth and proliferation of prostate cancer cells. An international research team discovered this when studying the enzyme "soluble adenylyl cyclase" that produces the second messenger molecule cAMP. When the scientists ...

Remote sensing, microbiology used to trace foodborne pathogens

06-12-2012

In 2011, an outbreak of Listeria monocytogenes in cantaloupe led to almost 150 illnesses and 30 deaths. With a spate of recent outbreaks of such foodborne pathogens as Salmonella, Shiga toxin-producing E. coli and L. monocytogenes, the ability to predict where and how these deadly microbes ...

Decoded genome paves way for better watermelons

29-11-2012

Sweeter and more disease-resistant watermelons just may be on their way, thanks to an international consortium of more than 60 scientists that has just published the genome sequence of watermelon (Citrullus lanatus). Such information could dramatically accelerate breeding to produce more ...

The sorcerer's apprentice started a water-carrying system, but couldn't stop it, and soon he was up to his neck in water, and trouble. Living cells have a better design: When they activate a gene, they have a system in reserve to turn it off. The cell does not want to waste energy making ...

In a two-day-old mouse, a heart attack causes active stem cells to grow new heart cells; a few months later, the heart is mostly repaired. But in an adult mouse, recovery from such an attack leads to classic after-effects: scar tissue, permanent loss of function and life-threatening ...
