Green R&D - Hypergiant Algae is a single-celled organism that is capable of multiplying rapidly through the absorption of sunlight and carbon dioxide. It is considered one of nature’s most efficient machines. Algae can be grown nearly anywhere and it requires very few nutrients to survive. It is high in proteins, lipids, and starches, making it suitable for a variety of uses, including as food. The Hypergiant Eos Bioreactor uses algae, specifically Chlorella Vulgaris which is capable of pulling CO2 from the atmosphere at a much higher rate than any other plant. Algae is the central ingredient in our bioreactor.

antigenic shift - definition Antigenic shift: A sudden shift in the antigenicity of a virus resulting from the recombination of the genomes of two viral strains. Antigenic shift is seen only with influenza A viruses. It results usually from the replacement of the hemagglutinin (the viral attachment protein that also mediates the entry of the virus into the cell) with a novel subtype that has not been present in human influenzaviruses for a long time. The source of these new genes is the large reservoir of influenzaviruses in waterfowl. The consequences of the introduction of a new hemagglutinin into human viruses is usually a pandemic, or a worldwide epidemic.

Could humans be Earth's second civilization? “How do you know we’re the only time there’s been a civilization on our own planet?” [said Goddard Institute for Space Studies director Gavin Schmidt]. [T]hat first conversation launched a new study we’ve recently published in the International Journal of Astrobiology. Substitution Mutation Substitution Mutation Definition A substitution mutation is a type of replication error during DNA replication which places the wrong nucleotide or sequence of nucleotides in the wrong position. A type of substitution mutation, a point mutation, occurs which a single nucleotide is substituted. This can be seen in the image below.

MACH: The best and latest in Tech & Innovation Dominic Hogdson / Sentinel-2/ESA Environment Iceberg's break from Antarctic ice shelf is 'geologically imminent' Scientists are eyeing a huge crack in the ice that has grown more than 650 feet in the past month. U.S. news Analysis predicts extremely disruptive, total transition to EV / autonomous vehicles in 13 years (Tech Xplore)—RethinkX, an independent think tank that analyzes and forecasts disruptive technologies, has released an astonishing report predicting a far more rapid transition to EV/autonomous vehicles than experts are currently predicting. The report is based on an analysis of the so-called technology-adoption S-curve that describes the rapid uptake of truly disruptive technologies like smartphones and the internet. Additionally, the report addresses in detail the massive economic implications of this prediction across various sectors, including energy, transportation and manufacturing. Rethinking Transportation 2020-2030 suggests that within 10 years of regulatory approval, by 2030, 95 percent of U.S. passenger miles traveled will be served by on-demand autonomous electric vehicles (AEVs).

Weird things start to happen when you stare into someone's eyes for 10 minutes Giovanni Caputo recruited 20 young adults (15 women) to form pairs. Each pair sat in chairs opposite each other, one metre apart, in a large, dimly lit room. Specifically, the lighting level was 0.8 lx, which Caputo says "allowed detailed perception of the fine face traits but attenuated colour perception." The participants' task was simply to stare into each other's eyes for 10 minutes, all the while maintaining a neutral facial expression. A control group of a further 20 participants also sat in a dimly lit room in pairs, but their chairs faced the wall and they stared at the wall. Beforehand both groups were told that the study was going to involve a "meditative experience with eyes open."

What is this thing called science? As a scientist, Evelyn Fox Keller hated experiments. Today a professor emerita in the History of Science at MIT, she started out her scientific career in theoretical physics before jumping to molecular biology. What got her was the trivial volatility inherent in experimentation. “Someone could brush by the thermostat on the water bath, and a months’ work would be down the drain. You didn’t have control over it.” Physical Review X Does Research on Foundations of Quantum Mechanics Fit into PRX’s Scope? October 24, 2014 The editors and Bill Poirier from Texas Tech University spotlight an original, thought-provoking paper by Hall, Deckert, and Wiseman on foundations of quantum mechanics, Phys.
