Pacific Gas and Electric Company (PG&E) is a subsidiary of PG&E Corporation and is a major natural gas utility in the USA. The company is now testing a new device for the detection of methane leaks based on an instrument of the Mars Rover Curiosity. Developed to find out if there is methane on Mars, a possible trace of biochemical reactions, this instrument is a thousand times more sensitive than those used so far by PG&E to detect leaks of methane.

Google announced the Baseline Study project, a detailed study on the biological level of human beings to determine what a healthy person should be. The initial study includes 175 people of which an enormous amount of medical information will be collected. A team that includes dozens of specialists led by molecular biologist Andrew Conrad will use this information to create a portrait of a person in perfect health.

Frederick Sanger

Yesterday Frederick Sanger died. He was a British biochemist described by many as one of a fathers of genetics and one of the greatest scientists in the world and not only of his generation. Born in 1918, he received two Nobel Prizes in Chemistry: one in 1958 and one in 1980.
