The mats, which the researchers believe are likely similar to the type that evolved in some early lagoons during the Ediacaran Period, some 542 million years ago (the time most agree multicellular animals first began to appear) are comprised of a bottom layer of sulphide-oxidizing bacteria, which is covered by a top layer of blue green algae, which produces the oxygen through photosynthesis. They found oxygen levels of between 0.25 and 0.45 atm near the mats, compared to 0.10 at or near the surface.The findings are important because fossil evidence suggests mobile animals first evolved in early salty lagoons that should have been too salty to produce normal plant growth.Of course there is one hiccup in the theory, and that is the fact that the mats only produce oxygen during the day when the sun is shining; oxygen levels around the mats plunge at night, leaving the lagoons a very inhospitable place. However, at Los Roques, there are some insect larvae that exist inside the mats that for the most part shut down at night; hibernating, if you will, and thus can survive with almost no oxygen when it’s dark. Gingras and his team support the notion that perhaps some early life forms could have done the same, though others are not quite ready to jump on that bandwagon.Another issue is that the results are based on the notion that the mats that exist today are in fact the same as the mats that existed way back then; a bit of a leap seeing as how there is really no evidence to support such a supposition. Thus, in order for the ideas suggested in this paper to gain credence, evidence of some similarity will have to be found through further research. © 2010 PhysOrg.com This document is subject to copyright.

In situ fossils of the mobile forms of these animals are associated with microbial sedimentary structures1, 2, 3, and the animal’s trace fossils generally were formed parallel to the surface of the seabed, at or below the sediment–water interface4, 5. This evidence suggests the earliest mobile animals inhabited settings with high microbial populations, and may have mined microbially bound sediments for food resources6, 7, 8. Here we report the association of mobile animals—insect larvae, oligochaetes and burrowing shore crabs—with microbial mats in a modern hypersaline lagoon in Venezuela. The lagoon is characterized by low concentrations of dissolved O2 and pervasive biomats dominated by oxygen-producing cyanobacteria, both analogous to conditions during the Ediacaran. We find that, during the day, O2 levels in the biomats are four times higher than in the overlying water column. We therefore conclude that the animals harvest both food and O2 from the biomats. In doing so, the animals produce horizontal burrows similar to those found in Ediacaran-aged rocks. We suggest that early mobile animals may have evolved in similar environments during the Ediacaran, effectively exploiting oases rich in O2 that formed within low oxygen settings.

Image illustration: Nature Geoscience, doi:10.1038/ngeo1142 (PhysOrg.com) — Researchers from Canada studying the highly salty coastal lagoons at Los Roques, Venezuela and the microbial mats found at the bottom of the sea there, have discovered that oxygen levels in the mats, at least in the day time, are high enough to support the development of mobile life forms. Led by University of Alberta palaeontologist, Murray Gingras, the team writes in Nature Geoscience, that levels of oxygen on the ocean floor were up to four times as high as that near the surface; high enough to support the development of mobile sea life; which the team believes could explain how early life forms could have evolved in waters with high salt concentrations.

Other issues such as sonic booms and the safety of not just those aboard, but those on the ground that lie in its path will need to be addressed as well. Engineers and managers working on the project are well aware of the difficult issues of course, but by publicly announcing their goal, they have shown that they are confident that they will succeed. Credit: DLR-SART The SpaceLiner project has been around since 2005, and is supported by the European Space Agency. The goal is to build a vehicle similar to the space shuttle flown previously by the United States – the main differences would be that the vehicles’ purpose would be to transport people from point to point across the globe and that it would not actually ever reach space. It would also be launched using liquid oxygen and hydrogen based propellants – only hydrogen and water vapor would be left behind in the atmosphere, a much cleaner approach than that used by other rockets.As with the space shuttle, a SpaceLiner vehicle would launch vertically, attached to a rocket booster. Passengers (up to 50) would be taken to an altitude of 47 to 50 miles, at which point the booster would fall away. From that point on, the craft would glide down to Earth on a trajectory that would have it arrive at its pre-designated destination. As the craft glides, it would reach speeds of up to 15,000 mph, which would account for the short travel time. But such plans also pose a problem for engineers as the vehicle would experience the same heat buildup as space reentry vehicles. For that reason, the design of the craft itself is still a work in progress. Engineers are analyzing the results of FAST20XX, a joint European project that has been studying the types of high speed craft that might carry people in the not so distant future. They will also no doubt be consulting with NASA on lessons learned from the space shuttle program. © 2013 Phys.org (Phys.org)—Martin Sippel, project coordinator for the SpaceLiner project has announced that the German Aerospace Center believes it can plan, build and launch a suborbital craft capable of flying from Europe to Australia in just 90 minutes, in as few as 50 years.

Scientists know that the first modern humans to migrate to Europe were hunter-gatherers—they arrived approximately 40,000 years ago. But then, the hunter-gatherers were slowly replaced by new migrants from the Near East approximately 9,000 years ago—migrants that were farmers. But the path they took has been under dispute by historians. In this new effort the researchers sought to lay the arguments to rest by conducting an exhaustive DNA study of the people that live in the region today.The team collected DNA samples from 964 people living in 32 different places in the region—from northern Africa, to the Middle and Near East to islands in the Mediterranean Sea, to the European continent. Each of the DNA samples was scrutinized for markers known as single-nucleotide polymorphisms (SNPs). People from the same place tend to have SNPs in common, which makes tracking their migration possible by looking for such markers in different populations. Analysis of the samples allowed the researchers to trace the movement of early people from the fertile crescent in the Middle East, to the Near East and into Turkey, and then as they sailed to nearby islands off the southern coast and finally, as they arrived on the southern shores of mainland Europe.

The researchers note that despite the lack of archeological evidence, such as boats used by the migrants, the DNA analysis allowed for near certainty in plotting the course of Neolithic migration of early farmers to Europe. The SNPs showed very clearly, they claim, the path that the people took, thus, island hopping may be considered the main, if not only route that was taken. That would rule out such possibilities as a northern land route from Turkey to Europe through the Bosphorus strait, or farmers sailing directly to Europe from the Middle East.

An alternative route would have been island hopping across the Southern European coast. To test this hypothesis, we analyzed genome-wide DNA polymorphisms on populations bordering the Mediterranean coast and from Anatolia and mainland Europe. We observe a striking structure correlating genes with geography around the Mediterranean Sea with characteristic east to west clines of gene flow. Using population network analysis, we also find that the gene flow from Anatolia to Europe was through Dodecanese, Crete, and the Southern European coast, compatible with the hypothesis that a maritime coastal route was mainly used for the migration of Neolithic farmers to Europe.Press release Genetic markers in modern populations indicate the Neolithic migrants who brought farming to Europe traveled from the Levant into Anatolia and then island hopped to Greece via Crete and then to Sicily and north into Southern Europe.

Although significant progress has been achieved in recent years in designing observational tests of gravity’s effects in the universe that might reveal the presence of modified gravity, there is still no conclusive evidence for its existence.Now in a new paper published in Physical Review Letters, Wojciech A. Hellwing, et al., have proposed a new test of modified gravity that is based on measuring the tendency of well-separated galaxies to approach each other. This movement is called the galaxy pairwise velocity. The physicists show that the galaxy pairwise velocity distribution of many galaxies with a wide range of masses is expected to deviate from the predictions of general relativity by significant amounts: between 5 and 10 standard deviations or higher, depending on the model. Due to these large deviations, this proposed test could potentially offer the strongest evidence in support of modified gravity to date.”Modified gravity (MG) theories have gained a lot of attention in the last decade,” Hellwing, a researcher at Durham University in the UK and the University of Warsaw in Poland, told Phys.org. “Mostly because this class of theories provides an alternative explanation of the late-time accelerated expansion of the universe, while avoiding some conceptual problems related to the classical general relativity (GR) picture in which Einstein’s cosmological constant is supposed to drive this acceleration. In the classical GR picture, one needs to have a very small value of the cosmological constant, which is hard to reconcile with quantum field theory. MG theories provide an alternative explanation, but in most of these theories modifications to gravity not only can account for accelerated expansion but also can produce non-negligible enhancement to gravity at cosmic scales relevant to galaxy formation and dynamics. Therefore it is of utmost importance to find observational evidence that could distinguish between these two scenarios (GR or MG).” Study finds ‘lumpy’ universe cannot explain cosmic acceleration A thin slice of the large-scale cosmic density field (the clustering of dark matter and galaxies) is depicted for four models: GR and three different MG models.

Credit: ” Monthly Notices of the Royal Astronomical Society, Volume 428, Issue 1, p.743-755 (Phys.org) —Since 1916, general relativity has provided a description of gravity that can explain many observations, including objects in free fall, gravitational lensing by massive objects, and black holes. Despite the success of the theory for nearly 100 years, scientists have been looking at ways to modify general relativity in order for it to better explain certain observations—particularly the accelerated expansion of the universe. Although these modifications can be very different from one another, they generally fall into the category of “modified gravity.” Although one possible type of observational evidence of MG is related to the clustering of luminous galaxies, Hellwing explained that these observations have been plagued by ambiguities connected to non-linear baryonic physics responsible for galaxy formation and clustering. The complications make it very difficult to find a clear and measurable signal that could help researchers distinguish between GR and MG scenarios. Citation: New test may provide ‘smoking gun’ for modified gravity (2014, June 20) retrieved 18 August 2019 from https://phys.org/news/2014-06-gun-gravity.html “In our paper we have shown that the peculiar velocities of galaxies bear a significant signal of the underlying theory of gravity,” Hellwing said. “The advantage here is that the galaxy velocities are much less prone to the effects of the non-linear baryonic physics of galaxy formation. We also show this in our paper, when we present that the MG signal is present for galaxies of all masses and can also be measured both on large and small cosmological scales. Thanks to these unique features connected to the statistics of the galaxy velocity field, these kinds of observables pose a clean ‘smoking gun’-like signature of either GR or MG.”The physicists explain that the MG signal can be measured in two ways because it involves two different observational data sets. One set consists of the data of galaxy peculiar velocities, the other the clustering of galaxies in so-called redshift space. In the latter, the galaxy positions (clustering) are affected by their peculiar velocities and in the former the galaxy velocities are measured directly. “Both data sets call for a different approach,” Hellwing said. “However, the quality of the current data should allow for a clear measurement of the signal we discuss. Redshift space data is very abundant but it needs an extra theoretical effort to model properly the expected signal in GR and MG. The velocity data can be interpreted directly but it is much sparser and contained by much larger observational errors. A program aimed to extract the signal we have predicted theoretically is already in progress.”If experiments confirm that a modified version of general relativity can explain observations better than the original version, the results could shed light on some fundamental cosmological questions.”The implications of measuring the signal we have found are very profound,” Hellwing said. “Firstly the GR commonly adopted as a crucial ingredient of the standard cosmological model has only being tested at scales corresponding to the Solar System. Einstein’s theory was never directly tested on cosmological scales (relevant to galaxy velocities). Confirming that the GR is a valid theory of gravitation also on intermediate cosmological scales is very important. On the other hand, if the measured signal will indicate that GR is not enough to explain the observed motion of galaxies, then we will be dealing with a paradigm shift and a real breakthrough in modern cosmology and physics, comparable in magnitude to the accelerated expansion discovered in the late ’90s of the 20th century.” Journal information: Physical Review Letters , Monthly Notices of the Royal Astronomical Society A schematic picture of how researchers can observe galaxy peculiar velocities, “a cosmic dance of galaxies.” Credit: Wojciech A.

Located some 4,000 light years away from the Earth, CoRoT-20 is a star of spectral type G2V, similar in size and mass to our sun. In 2011, astronomers found a planet orbiting this star on a short-period eccentric orbit. The exoworld, which received designation CoRoT-20 b, is about the size of Jupiter but four times more massive. The exoplanet, classified as a “hot Jupiter,” circles its host every 9.24 days at a distance of approximately 0.09 AU from it.Now, a team of researchers led by Javiera Ray of the Geneva Observatory in Switzerland, have found a new substellar object in this system, also on an eccentric orbit, but with a much longer orbital period than that of CoRoT-20 b. The discovery was made as a result of follow-up observations of the CoRoT-20 system conducted between November 2011 and November 2017, using the HARPS and SOPHIE spectrographs.”In this paper, we report a new substellar companion orbiting CoRoT-20, thanks to six years of additional observations obtained with HARPS and SOPHIE spectrographs,” the researchers wrote in the paper.Observations carried out by Ray’s team show that the newly detected object, designated CoRoT-20 c, has a minimum mass of 17 Jupiter masses. Due to its mass, CoRoT-20 c was initially classified as a brown dwarf. Although the boundary between planet and brown dwarf is poorly defined, astronomers generally agree that brown dwarf are substellar objects at least 13 times more massive than Jupiter.According to the study, CoRoT-20 c is separated from its parent star by approximately 2.9 AU. The planet has an orbital period of 4.59 years and orbital eccentricity of 0.6.Notably, orbital parameters of the newly identified brown dwarf make CoRoT-20 the first known system with an eccentric “hot Jupiter” and an eccentric massive companion.”CoRoT-20 is the first identified system with an eccentric hot Jupiter (e ≥ 0.2) and an eccentric massive companion with a fully probed orbit,” the paper reads.The researchers noted that the newly detected brown dwarf interacts with the “hot Jupiter,” adding that the currently high eccentricity of CoRoT-20 b is likely entirely due to the presence of CoRoT-20 c.Due to this interaction, the CoRoT-20 system is perceived by Ray’s team as an excellent candidate to test tidal migration models. So far, astronomers have identified at least three migration mechanisms that can explain the existence of close-in “hot Jupiters” on eccentric orbits. Therefore, further observations of CoRoT-20 c, during its next transit, which is expected to occur in late 2020, could help us advance our understanding of these mechanisms.

As Dr. Salganik explained, even if a system is gamed, the worst product probably won’t end up at the top of your screen for long; assuming there’s a considerable difference in quality among the options, it will eventually be knocked down. But if the products are pretty similar, then yes, it’s possible that the very best one will actually not float to the very top — though that’s no tragedy either. As Barry Schwartz, the author of “The Paradox of Choice,” argues, if everything is essentially the same, then there’s nothing wrong with ending up with a product that’s the second- or third-best of the heap. Read the whole story: The New York Times Last Saturday, I was desperate for Mozart sheet music. It had to be for piano, and it had to be easy to play. Out of 84 options on Amazon, a book with 4.7 stars caught my eye — good enough for a 9-year-old’s music-class presentation. Later that afternoon, I needed to book a hotel for our summer vacation and I trusted the 1,310 reviewers on TripAdvisor who gave my pick an average of four stars, along with a good number of “fantastics” and “wonderfuls.” It’s not that I’m afraid of a little research. As a writer at Wirecutter, The New York Times’s product review site, I pore over user ratings professionally, though I don’t rely on them solely. For my review of foam mattresses, I focused my efforts on extensive reporting and slept on the mattresses myself. I analyzed online comments to deduce trends, and I certainly didn’t take stars at face value. Dinner was a 4.5 star meatloaf recipe. And this weekend, with Memorial Day sales in full swing, I will turn to an army of online reviewers who will help me bite the bullet and replace a toilet that has mysteriously begun flushing of its own accord. Someone else will have put the time in at Home Depot so I don’t have to. — But which someone? Who are these reviewers I’m trusting with my purchasing decision, big and small? I don’t know for sure, and yet I feel completely stalled until I’ve scrolled through everything they have to say.

It’s almost a faraway world from our city-centric lives; a world where everything is alive- the rocks, the leaves, and the atmosphere around. That is what physics says as well. Shamanistic traditions emphasize upon an interconnected web of life; you disturb its balance, and its repercussions come back to you.

Still, during the course of the film, was there anything that left you flabbergasted? Share an anecdote with us. I was shooting Gur Tularam, a shaman of goddess Hadimba in the Kullu valley. Hadimba is a demon goddess. When Tularam goes into a trance, it’s terrifying to see him as he turns violent over a period of time. I could feel his waves of energy travelling to me and I was left flabbergasted with goosebumps on my skin. Shooting this four-hour -long documentary was a massive exercise. I remember chasing a procession of Shamans. I was almost jumping around with my small camera to keep up with their pace. There has been a pattern to your documentaries; you seem to be travelling to a new state with every fresh documentary you make. I started my television career in the 90s with travel shows. During that time, I used to drive or travel around the country all the time. Wherever I went, I found a new culture, a different way of life. This is what inspires me to document the fragile and vulnerable aspects of life in India for posterity. If these cultures get lost with the passage of time, a way of life will be lost, leaving us empty for forever.
