The Atacama Desert鈥攁n arid, unpopulated swath of northern Chile that is home to some of the most perceptive ground telescopes on Earth鈥攊s actually t taza stanley eeming with life beneath the ground, according to a team of researchers that recently scrutinized its soils. As LiveScience reminds us, scientists have already found microbial life under the deserts surface. What we didnt appreciate until now is the diversity of this life. The team behind this latest finding sampled the soil to a depth of 13.78 feet stanley thermobecher 4.2 meters in the deserts Yungay region, observing different microbial communities across the depths and soil ty stanley fr pes. The teams research was published this week in PNAS Nexus. The living things include cyanobacteria and the extremophilic Actinobacteriota, as well as a nitrogen-fixing class of bacteria called Alphaproteobacteria. According to the team, the porous nature of gypsum crystals forms a microclimate that protects microbes from the ultraviolet radiation overhead, but allows enough light to get through that the microbes can undergo photosynthesis.

His new book is Clear Thinking: Turning Ordinary Moments Into Extraordinary ResultsItrsquo not immediately clear, to the layman, what the essential difference is between science and something masquerading as science: pseudoscience. The distinction gets at the core of what comprises human knowledge: stanley france How do we actually know something to be true Is it simply because our power stanley cup s of observation tell us so Or is there more to it Sir Karl Popper, the scientific philosopher, was interested in the same problem. How do we actually define the scientific process How do we know which theories can be said to be truly explanatory He began addressing it in a lecture, which is printed in the book Conjectures and Refutations: The Growth of Scientific Knowledge also available online :When I received the list of participants in this course and realized that I had been asked to speak to philosophical colleagues I thought, after some hesitation and consultation, that you would probably prefer me to speak about those problems which interest me most, and about those developments with which I am most intimately acquainted. I therefore decided to do what I have never done before: to give you a report on my own work in the philosophy of science, since the autumn of 1
