A primitive, non-photosynthesizing microbe, Methanospirillum hungatei, which is thought to have existed since before the development of photosynthesis, possess genes similar to those that play a role in photosynthesis, finds a new study.

Photosynthesis, creating oxygen and carbohydrates such as glucose from solar energy, water, and CO2, is indispensable for many species on this planet. However, it is unclear exactly how or when organisms evolved the ability to photosynthesize. A team has discovered an evolutionary model for the biological function that creates CO2 from glucose in photosynthesis. 
Though scant progress has been made in treating or understanding Alzheimer's disease in the last 100 years, one thing is known; there are declines in glucose levels in the hippocampus early on. What has remained unclear is whether that is a cause or consequence. 
Mitochondrial dysfunction, which leads to rare genetic disorders in children, some forms of heart disease, and most likely some cases of Parkinson’s disease, is bewildering in the variety and complexity of problems it can cause. 

Mitochondria are, after all, the energy factories contained inside most of our cells, they convert the diverse food we consume into a common energy type. No energy, no life. 
Holy grail -againAfter being only theorized for 80 years, Harvard scientists claim they have succeeded in creating the rarest - and potentially one of the most valuable - materials on the planet.
The number of theoretically possible fatty acids with the same chain length but different structures can be determined with the aid of the famous Fibonacci sequence.

The ability to calculate the number of possible fatty acids is of great importance for their chemical analysis (‘lipidomics’) and a new paper states the number of possible fatty acids with increasing chain length rises at each step by a factor that agrees with what is called the ‘Golden Ratio’. The Golden Ratio is essentially a ratio that is the midpoint between asymmetry and symmetry, when "the whole is to the larger as the larger is to the smaller". In numerical terms, it is 1.618.
A new analysis finds that youths who hold off on trying marijuana until age 17 do better on cognitive tests and drop out of school at a lower rate than those who start by age 14. Obviously negative health behavior in alcohol and cigarettes are linked in the same ways, but those two have not gotten the health halo that marijuana has gotten, thanks to politicians who have turned a blind eye to health concerns in the interest of generating more revenue.
