The phenomenon is called “sexually antagonistic grandparental care,” and it has been known for some time that a grandmother will naturally prefer her son’s daughters (with whom she shares 31 percent of her genes) to her son’s sons (with whom she shares only 23 percent, suggesting she will most nurture the grandchild who inherits more of her genes.

A father has an XY chromosome pair, with the X derived from his mother and the Y derived from his father. He passes copies of the X to his daughters and Y to his sons. This has evolutionary consequences, according to Friberg’s team, because of the innate drive to ensure the survival of our genes in future generations. The team developed a new paradigm they called the “no-cost-to-self nepotism” rule to generate predictions about the behaviors of grandparents.The major prediction the group found was that grandmothers (and to a lesser degree, grandfathers) will evolve grandson-harming phenotypes that effectively reduce the competition between siblings, and favor their more closely related granddaughters, especially daughters of their sons (who have definitely inherited the grandmother’s X chromosome).Women always know their children are their own, while fathers always have some uncertainty because of the possibility they were cuckolded. This means maternal grandmothers know for certain their grandchildren are recipients of copies of their genes, while paternal grandfathers are doubly uncertain about the genetic inheritance of their grandchildren. The results of the current research supports the findings of previous studies that showed a baby girl’s chances of survival are increased if a paternal grandmother cares for her, while a boy’s chances are diminished. If a maternal grandmother is involved, the boys have improved chances of survival.The results of the study are published in the Proceedings of the Royal Society B.

Nanosilicon rapidly splits water without light heat or electricity

first_img The researchers, Folarin Erogbogbo at the University of Buffalo and coauthors, have published their paper on using nanosilicon to generate hydrogen in a recent issue of Nano Letters.If hydrogen is ever to be used to deliver energy for wide commercial applications, one of the requirements is finding a fast, inexpensive way to produce hydrogen. One of the most common hydrogen production techniques is splitting water into hydrogen and oxygen. There are several ways to split water, such as with an electric current (electrolysis), heat, sunlight, or a substance that chemically reacts with water. Such substances include aluminum, zinc, and silicon.As the scientists explained, silicon-water oxidation reactions have so far been slow and uncompetitive with other water splitting techniques. However, silicon does have some theoretical benefits, such as being abundant, being easy to transport, and having a high energy density. Further, upon oxidation with water, silicon can theoretically release two moles of hydrogen per mole of silicon, or 14% of its own mass in hydrogen.For these reasons, the scientists decided to take a closer look at silicon, specifically silicon nanoparticles, which have not previously been studied for hydrogen generation. Because silicon nanoparticles have a larger surface area than larger particles or bulk silicon, it would be expected that the nanoparticles can generate hydrogen more rapidly than the larger pieces of silicon. (Phys.org)—Although scientists know that when silicon mixes with water, hydrogen is produced through oxidation, no one expected how quickly silicon nanoparticles might perform this task. As a new study has revealed, 10-nm silicon nanoparticles can generate hydrogen 150 times faster than 100-nm silicon nanoparticles, and 1,000 times faster than bulk silicon. The discovery could pave the way toward rapid “just add water” hydrogen generation technologies for portable devices without the need for light, heat, or electricity. Journal information: Nano Letters But the improvements the scientists discovered with silicon nanoparticles far exceeded their expectations. The reaction of 10-nm silicon particles with water produced a total of 2.58 mol of hydrogen per mol of silicon (even exceeding theoretical expectations), taking 5 seconds to produce 1 mmol of hydrogen. In comparison, the reaction with 100-nm silicon particles produced a total of 1.25 mol of hydrogen per mole of silicon, taking 811 seconds to produce each mmol of hydrogen. For bulk silicon, total production was only 1.03 mol of hydrogen per mol of silicon, taking a full 12.5 hours to produce each mmol of hydrogen. For a rate comparison, the 10-nm silicon generated hydrogen 150 times faster than 100-nm silicon and 1,000 times faster than bulk silicon. “I believe the greatest significance of this work is the demonstration that silicon can react with water rapidly enough to be of practical use for on-demand hydrogen generation,” coauthor Mark Swihart, Professor of Chemical and Biological Engineering at the University of Buffalo, told Phys.org. “This result was both unexpected and of potential practical importance. While I do not believe that oxidation of silicon nanoparticles will become a feasible method for large-scale hydrogen generation any time soon, this process could be quite interesting for small-scale portable applications where water is available.” Just add water: How scientists are using silicon to produce hydrogen on demand In addition to producing hydrogen faster than larger silicon pieces, the 10-nm silicon also produces hydrogen significantly faster than aluminum and zinc nanoparticles. As Swihart explained, the explanation for this inequality differs for the two materials. “Compared to aluminum, silicon reacts faster because aluminum forms a denser and more robust oxide (Al2O3) on its surface, which limits the reaction,” he said. “In the presence of a base like KOH [potassium hydroxide], silicon mostly produces soluble silicic acid (Si(OH)4). Compared to zinc, silicon is simply more reactive, especially at room temperature.”Although the larger surface area of the 10-nm silicon compared with larger silicon pieces contributes to its fast hydrogen production rate, surface area alone cannot account for the huge rate increase that the scientists observed. The surface area of 10-nm silicon is 204 m2/g, about 6 times greater than the surface area of 100-nm silicon, which is 32 m2/g. To understand what causes the much larger increase in the hydrogen production rate, the researchers conducted experiments during the silicon etching process. They found that, for the 10-nm particles, etching involves the removal of an equal number of lattice planes in each direction (isotropic etching). In contrast, for 100-nm particles and microparticles, unequal numbers of lattice planes are removed in each direction (anisotropic etching). The researchers attribute this etching difference to the different geometries of different-sized crystals. As a result of this difference, the larger particles adopt non-spherical shapes that expose less reactive surfaces compared to the smaller particles, which remain nearly spherical, exposing all crystal facets for reaction. Larger particles also develop thicker layers of oxidized silicon byproducts through which water must diffuse. Both of these factors limit the rate of the reaction on larger particles.To confirm that that the 10-nm silicon-water reaction generates hydrogen with no byproducts that could interfere with applications, the researchers used the silicon-generated hydrogen to operate a fuel cell. The fuel cell performed very well, producing more current and voltage than the theoretical amount of pure hydrogen, which is due to the fact that the 10-nm particles generated more hydrogen than the theoretical 14 wt %.The researchers hope that this surprising ability of silicon nanoparticles to rapidly split water and generate hydrogen could lead to the development of a hydrogen-on-demand technology that could enable fuel cells to be used in portable devices. This technology would require a large-scale, energy-efficient method of silicon nanoparticle production, but could have some advantages compared to other hydrogen generation techniques.”The key advantage of silicon oxidation for hydrogen generation is its simplicity,” Swihart said. “With this approach, hydrogen is produced rapidly, at room temperature, and without the need for any external energy source. The energy needed for hydrogen generation is effectively stored in the silicon. All of the energy input required for producing the silicon can be provided at a central location, and the silicon can then be used in portable applications.”The key disadvantage of silicon oxidation is its relative inefficiency. The energy input required to create the silicon nanoparticles is much greater than the energy available from the hydrogen that is finally produced. For large scale applications, this would be a problem. For portable applications, it is not. For example, the cost of electricity supplied by an ordinary household battery can easily be 10 to 100 times higher than the cost of electricity from a utility, but batteries still play an important role in our lives.”In the future, the researchers plan to further increase the hydrogen generation capacity of silicon oxidation by experimenting with different mixtures.”One direction that we are presently pursuing is the use of mixtures of silicon nanoparticles with metal hydrides, which also react with water to produce hydrogen,” Swihart said. “Compounds like lithium hydride and sodium hydride react with water to produce the base (LiOH or NaOH) that is needed to catalyze the silicon oxidation. However, they can react too fast with water (explosively) and are not stable in air. Mixing them with silicon nanoparticles or coating them with silicon nanoparticles may serve to both temper their reactivity and increase the hydrogen generation capacity of the system by replacing the added base (e.g., KOH in the published paper) with a material that also generates hydrogen.” A comparison of hydrogen generation rates for different forms of silicon.

In another part of the experiment, the researchers examined the stressed crayfish and found they had elevated levels of serotonin, the same neurotransmitter that has been found to be elevated in stressed humans. The team found that they could cause the same types of protective behavior in the crayfish just by injecting them with serotonin. They also found that they could calm the crayfish by injecting them with chlordiazepoxide, a drug used to treat anxiety in humans—afterwards the stressed subjects ventured into the well-lit parts of the tanks in much the same ways as the unstressed crayfish.

Prior research has shown that stress is hard on people, both mentally and physically. For that reason, scientists have been searching for many years for ways to alleviate the stress that people feel—they’ve come up with many solutions, from advocating exercise to administering pharmaceuticals. None have been found to be the ultimate cure, however, so the search continues. In this new effort, the researchers in France studied anxiety behavior due to stress in crayfish to gain a new perspective on the condition and perhaps ways to treat it.To find out how crayfish respond to stress, the researchers subjected several of them to mild electric shocks then placed them into a specially designed tank of water—it was shaped like a cross, with two wings well lit, and two left in the dark. The researchers found that when the stressed crayfish were placed into the tank, they tended to avoid the well lit wings—a protective sort of behavior. Unstressed crayfish placed in the tank were tentative but did eventually explore the well-lit parts of the tank as they searched for food.

Disrupted globular cluster found in the constellation of Draco

They used about 2.5 million stellar spectra available in the second data release of the LAMOST spectroscopic survey, searching through the spectroscopic dataset and looking for metallicity-velocity clumping inconsistent with the field.John Jason Vickers, who is the lead author of the study along with the co-authors, estimates that this cluster, named Lamost 1, has a total mass of about 25,000 solar masses and has luminosity approximately 15,000 times greater than our sun. The researchers are 90 percent sure that the stellar group is about 11 million years old.When studying Lamost 1’s characteristics, the scientists have also found that it could be a part of a larger structure.”The large physical size and the fact that the tangential velocity dispersion is so much higher than the radial velocity dispersion imply that this could be part of a tidal stream, although some tangential velocity dispersion is certainly an effect of proper motion uncertainty at this distance,” the paper reads.By knowing the velocity and position of the Lamost 1, the researches can tell that this clump is near a point in the orbit at which it is furthest from the center of its galaxy.However, there are doubts over whether Lamost 1 is really a disrupted globular cluster. The high metallicity indicates that there is possibility that the studied group is a large dwarf galaxy progenitor. On the other hand, the lack of a strong physical overdensity speaks against this hypothesis.”The stream’s progenitor could be either a dwarf galaxy or a star cluster. The high metallicity of our stream implies that if the progenitor were a dwarf galaxy, it should be relatively massive, on par with that of the Sagittarius Dwarf. Since we do not see any prominent physical streams in the photometric data, we look to another possible explanation,” the astronomers noted in the paper.The elliptical orbit and advanced age of the clump supports the globular cluster origin theory. It was more likely a spherical collection of stars orbiting a galactic core once. “We postulate that this object is a star cluster being observed near the apocenter of its eccentric orbit. It manifests as a signature distinct from the background in velocity and metallicity space,” the scientists wrote.They conclude that the object of interest is likely to be a nearby, intermediate-age globular cluster which is being disrupted by the galactic potential. According to them, the spectroscopic technique provided by the LAMOST telescope could help uncover numerous known objects and structures, as well as more puzzling, unknown features like Lamost 1.last_img read more

Folktale diffusion traced using genomic data

first_img Study shows cultural flow may be slower than genetic divergence © 2017 Phys.org Most people today in the Western world are familiar with a handful of folktales, including “Hansel and Gretel,” “Sleeping Beauty,” “Cinderella” and “Rumpelstiltskin”—such tales typically have a moral or lesson. Those that struck a chord tended to be widely told and were passed down through the generations, first orally, then through books. The researchers with this new effort wanted to know whether such tales were distributed through the grapevine, so to speak, or whether they were carried by people moving from one place to another. To find out, they used some of the growing amount of publicly available genome data.For their study, the researchers made a list of what they deemed the 596 most famous folktales in Europe and Asia—then, they compiled another list containing titles and information about published folktales. Next, they extracted information from global genome databases that provided data regarding the movement of people over different time periods. Connecting the two types of data allowed the researchers to create flow charts that described the movement of folktales over time.The researchers were able to see that both types of distribution were involved in the spread of folktales. Some of the tales moved through populations until they reached a border, either physical or social, such as a language barrier. Others were able to make giant leaps as people traveled great distances, taking the tales with them and relating them to those they encountered. The team notes that they were also able to isolate approximately 15 of the tales that had clearly spread due to migration. The researchers report that they were also able to narrow down the origination sites of some common fables to regions as broad as Northern Africa or Central Asia. More information: Inferring patterns of folktale diffusion using genomic data, Eugenio Bortolini, PNAS, DOI: 10.1073/pnas.1614395114AbstractObservable patterns of cultural variation are consistently intertwined with demic movements, cultural diffusion, and adaptation to different ecological contexts [Cavalli-Sforza and Feldman (1981) Cultural Transmission and Evolution: A Quantitative Approach; Boyd and Richerson (1985) Culture and the Evolutionary Process]. The quantitative study of gene–culture coevolution has focused in particular on the mechanisms responsible for change in frequency and attributes of cultural traits, the spread of cultural information through demic and cultural diffusion, and detecting relationships between genetic and cultural lineages. Here, we make use of worldwide whole-genome sequences [Pagani et al. (2016) Nature 538:238–242] to assess the impact of processes involving population movement and replacement on cultural diversity, focusing on the variability observed in folktale traditions (n = 596) [Uther (2004) The Types of International Folktales: A Classification and Bibliography. Based on the System of Antti Aarne and Stith Thompson] in Eurasia. We find that a model of cultural diffusion predicted by isolation-by-distance alone is not sufficient to explain the observed patterns, especially at small spatial scales (up to ∼∼4,000 km). We also provide an empirical approach to infer presence and impact of ethnolinguistic barriers preventing the unbiased transmission of both genetic and cultural information. After correcting for the effect of ethnolinguistic boundaries, we show that, of the alternative models that we propose, the one entailing cultural diffusion biased by linguistic differences is the most plausible. Additionally, we identify 15 tales that are more likely to be predominantly transmitted through population movement and replacement and locate putative focal areas for a set of tales that are spread worldwide.

Massive brown dwarf detected by astronomers

first_img 2019 Science X Network An international team of astronomers has found a new brown dwarf, one of the most massive objects of this type discovered to date. The newly detected brown dwarf, designated EPIC 212036875 b, turns out to be about 50 times more massive than Jupiter. The finding is detailed in a paper published June 13 on arXiv.org. Brown dwarfs are intermediate objects between planets and stars. Astronomers generally agree that they are substellar objects occupying the mass range between 13 and 80 Jupiter masses. Notably, out of the 2,000 brown dwarfs so far detected, only about 400 of them were found to be circling around stars.Observations have shown that brown dwarfs with masses between 35 and 55 Jupiter masses orbiting their hosts at a relatively close distance (less than 3.0 AU) are extremely rare and difficult to find. This so-called “brown dwarf desert” is constantly studied by astronomers using various techniques, aiming to find other examples of this peculiar type.Now, an international group of researchers led by Carina M. Persson of Chalmers University of Technology in Sweden reports the finding of a new massive brown dwarf, apparently another representative of this desert. The new object, designated EPIC 212036875 b, was identified by NASA’s prolonged Kepler mission known as K2, and Persson’s team confirmed its brown dwarf nature using ground-based telescopes.”In this paper, we report the independent discovery and observations of EPIC 212036875 b performed by the KESPRINT consortium,” the paper reads as the detection of this object was almost simultaneously reported by other group of astronomers.According to the study, EPIC 212036875 b is about 51 times as massive as Jupiter, but approximately 17 percent smaller than our solar system’s gas giant. These values imply the brown dwarf’s mean density at a level of around 108 g/cm3.Observations conducted by Persson’s team found that EPIC 212036875 b orbits its host approximately every 5.17 days at a distance of about 0.06 AU from it. These results confirm that the newfound object represents the brown dwarf desert. Such a close orbit also means that the brown dwarf should be relatively hot—its equilibrium temperature is estimated to be about 1,450 K.The study reveals that the host, EPIC 212036875, is a slightly evolved star of spectral type F7 V, about 41 percent larger and 15 percent more massive that the sun. Its age was estimated to be around 5.1 billion years and its effective temperature was measured to be 6,230 K.In concluding remarks, the researchers ponder the possible formation and evolution scenarios for EPIC 212036875 b. They assume that this brown dwarf most likely formed due to gravitational instabilities in a protoplanetary disc.”We argue that EPIC 212036875 b formed via gravitational disc instabilities in the outer part of the disc, followed by a quick migration. Orbital tidal circularisation may have started early in its history for a brief period when the brown dwarf’s radius was larger,” the astronomers concluded. More information: Carina M. Persson et al.

Landscapes Recreated

first_imgPriyanka Govil is an artist who invests her creative energies into painting landscapes. But interestingly her works are not about landscapes as landscapes or landscapes in art history. Her work, basically reflects various natural and man-made things around her. Showing human tendency towards nature has become her major concern lately. In the conventional sense her works are not landscapes. But each time one looks at her works, one could see the places that exist somewhere in nature. They could be mental projections of the viewer or they could be the collective memories of her journeys.  Also Read – ‘Playing Jojo was emotionally exhausting’In her up-coming exhibition, at Art Konsult, her work will emphasis on importance of natural elements and intervention of man-made elements in a natural space. The fascination towards open spaces is a key point in her works. She considers these works as transformation stages where she merges landscapes with objects or shapes; treating them as part of a positive space. She treats them as cultural images representing social surroundings.The use of surface texture plays another signature role in her work.  In the landscapes and with the use of various other elements, she prefers to reduce the subjective elements to minimum details like adding lights to a particular section, just to suggest their presence. And these depictions become her way of telling stories.last_img read more
