- Recipe For Making Adult Stem Cells Behave Like Embryonic Just Got A Little Simpler
The simple recipe scientists earlier discovered for making adult stem cells behave like embryonic-like stem cells just got even simpler. A new report in the February 6th issue of the journal Cell shows for the first time that neural stem cells taken from a ...

- Fix A Broken Heart- Literally- With Adult Stem Cells
A little more than a year after University of Wisconsin-Madison scientists showed they could turn skin cells back into stem cells, they have pulsating proof that these "induced" stem cells can indeed form the specialized cells that make up heart ...

- Microbe Evolution 2.5 Billion Years Ago Began The Aerobic Nitrogen Cycle
As we mark the 200th anniversary of Charles Darwin's birth, there is much focus on evolution in animals and plants. But new research shows that for the countless billions of tiniest creatures – microbes – large-scale evolution was completed 2.5 billio ...

- Reverse Ecology- Reconstructing Bacterial Environments From Millions Of Years Ago
We learn a lot from genes but it turns out we can learn even more- like where you lived or even who you spent time with. It just requires knowing where and how to look. Researchers from Stanford and Tel-Aviv University are using a technique called " ...

- How Cells Survive Starvation: Self-Digestion
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 autophagosomes. It is a strategy that simple yeast cells have develope ...

- Old Cells Work Differently Than Young Ones
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 controlled removal of excessive protein. Scientists at Johann ...
