A discovery that’s set to rewrite textbooks on biology.
When power runs low, neurons start going haywire.
Maybe other drugs have similar effects.
It changes their genes.
Mitochondrial DNA is inherited only from the mother, and there’s a lot we can learn starting from this basic fact.
We’re living in the future.
A team led by Professor Jun-Ichi Hayashi from the University of Tsukuba in Japan, known as the white lion to his students given his white hair and powerful voice, challenges the current consensus surrounding the mitochondrial theory of aging, proposing epigenetic regulation, and not genetic mutation, may be responsible for the age-related effects seen in mitochondria. When Hayashi and colleagues tested their theory, they reversed the age defects in cell lines collected from 97-year-old Japanese participants. They then singled out two genes involved in glycine production which they believed are responsible for the mitochondria reversal. The findings thus suggest that a glycine supplementation could help curb aging or age-related diseases.
A new milestone study found that mitochondria – the energy factories in animal and plant cells – were initially very similar to parasitic bacteria some two billion years ago, and only later did they become energy sources. Very little is known about the origins of mitochondria, but by probing the genomes of bacteria closely related to the energy cell scientists at University
The recent discovery of DNA of a 400,000-year-old human thigh bone could provide valuable insight into the evolution of humans; researchers explain this is easily the oldest human genetic material ever found. When it comes to being a mountain, the Atapuerca Mountains in Spain don’t really have much going for them. It’s an ancient karstic region of Spain comprising mostly of
