A natural, biological pacemaker; that's what a heart is, right?  Sure, but our hearts can wear out and while artificial heart pacemakers have saved and extended the lives of thousands of…

Complex objects like automobiles and birthday cakes are created using a 'top down' process; the structure is imposed from the outside.    When things grow using order imposed from within,…

New genome sequence information from the humble baker's yeast has revealed surprising variation in a set of genes that can be thought of as nature's oldest clock. In a paper published in Genome…

Johns Hopkins researchers have discovered a new energy-making biochemical twist in determining the lifespan of yeast cells, one so valuable to longevity that it is likely to also functions in humans…

Results of the first human clinical studies confirm that a new yogurt fights the bacteria that cause gastritis and stomach ulcers with what researchers describe as almost vaccine-like effects,…

A preliminary study on the application of thermo-microbiology and its relation to time of death has been released by Professor Isabel Corcobado and colleagues at the University of Granada.  The…

 Cells keep up with the Joneses.  The peer pressure of signals from complementary cells tells a stem cell how and when to differentiate and grow.  Dr. Carolyn Bertozzi and her team at…

Sometimes known as "nature's origami", the way that proteins fold is vital to ensuring they function correctly. But researchers at the University of Leeds have discovered this is a 'hit and miss'…

The agglutination and accumulation of proteins in nerve cells are major hallmarks of age-related neurodegenerative illnesses such as Alzheimer's disease. Cellular survival thus depends on a…

In times of starvation, cells tighten their belts: they start to digest their own proteins and cellular organs. The process - known as autophagy - takes place in special organelles called…
