Oxygen is the newest gas found on Mars that appears to be acting in strange ways that may, theoretically, be an indirect sign of life on the planet. According to researchers studying the Gale Crater, a seasonal spike in oxygen levels does not appear to follow patterns of other gases which spike in spring and summer. According to Melissa Trainer, study leader, “”The fact that the oxygen behavior isn’t perfectly repeatable every season makes us think that it’s not an issue that has to do with atmospheric dynamics. It has to be some chemical source and sink that we can’t yet account for.” http://bit.ly/350EsJE

As physicists grow more comfortable with quantum entanglement, they are introducing the phenomenon into settings much larger than the subbatomic universe they were initially found in. An article in the Proceedings of the National Academy of Sciences comments, “physicists have taken entanglement and other quantum effects to new extremes by observing them in large systems including clouds of atoms, quantum drums, wires, and etched silicon chips. Device by device, they are bringing the quantum world into new territory—the macroscopic world.” Quantum computers and a completely new frontier in technology appears to be inching closer every day. http://bit.ly/2NJmRA4

For some time now, Ebola has been the poster-virus of messy, mostly lethal death. The name elicits immediate responses, mostly fear. Now, Science has had its say. As per Nature magazine, “The world finally has an Ebola vaccine. On 11 November, European regulators approved a vaccine that has already helped to control deadly outbreaks of the virus — the first time any immunization against Ebola has passed this hurdle.” Wonderful news. Let’s hear it for the scientific method… and Big Pharma. “Merck’s vaccine, which is marketed under the name Ervebo and known to researchers as rVSV-ZEBOV-GP, was tested in a clinical trial conducted in Guinea towards the end of the 2014–16 Ebola outbreak in West Africa.” https://go.nature.com/373fona

A recent study investigated whether a shift from sedentary behavior in older adults to more activity had measurable effects on cholesterol levels. The answer is yes. Just by moving around more, cholesterol levels decreased. So, everybody get up. http://bit.ly/2q2fxqi
