Cosmonauts find sea plankton on outside of International Space Station

Cosmonauts found traces of sea plankton and microscopic particles on outside of ISS.

ITAR-TASS, a Russian press agency, is reporting something so surprising that it’s hard to believe: Cosmonauts have found microorganisms on the exterior of the International Space Station. Russian scientists are shocked by this discovery and can’t really explain how it is possible.

Creating liquid fuel with electricity

isobutanol_bioconversion

Researchers have generated isobutanol from CO2 using a genetically engineered microorganism with solar electricity the sole energy input.

Electric vehicles have come a long way in the past decade, but they still have many disadvantages when compared to internal combustion engine-driven vehicles. The lithium-ion batteries that power electric vehicles have a much lower energy storage density when compared to liquid fuel, they take longer to “refuel,” and they lack the supporting infrastructure that has built up around conventional vehicles over the past century. Now researchers at the UCLA Henry Samueli School of Engineering and Applied Science have developed a process that could allow liquid fuel to be produced using solar generated electricity.

Darwin’s Theory of Universal Common Ancestry Confirmed in First Large-Scale Test

Darwin

More than 150 years ago, Darwin proposed the theory of universal common ancestry (UCA), linking all forms of life by a shared genetic heritage from single-celled microorganisms to humans. Until now, the theory that makes ladybugs, oak trees, champagne yeast and humans distant relatives has remained beyond the scope of a formal test. This week, a Brandeis biochemist reports in Nature the results of the first large scale, quantitative test of the famous theory that underpins modern evolutionary biology.

Nanomaterials Movement Measured in Simple Model Food Chain

New research* shows that while engineered nanomaterials can be transferred up the lowest levels of the food chain from single celled organisms to higher multicelled ones, the amount transferred was relatively low and there was no evidence of the nanomaterials concentrating in the higher level organisms.
