Citation: Is there a homosexuality gene? (2006, December 7) retrieved 18 August 2019 from https://phys.org/news/2006-12-homosexuality-gene.html Although biologists are still far from answering this question, scattered evidence for a possible gene influencing sexual orientation has recently encouraged scientists to map out a guide to future research. Because many possibilities for such a gene exist, scientists Sergey Gavrilets and William Rice have recently developed some theoretical guidelines and testable predictions for explaining the evolutionary causes of homosexuality.

I think that—when studying humans—many people shy away from studying sexual phenotypes in general and homosexuality in particular. Much of Sergey’s and my motivation in writing our paper was to rekindle an interest in studying the genetic basis of homosexuality. I personally think that if a firm genetic foundation for homosexuality in humans were established, then many people would view this fascinating human phenotype more objectively.”During the past several decades, scientists have discovered some interesting patterns that may point toward genetic causes of homosexuality. Among the findings is that male homosexuality appears to be inherited more often from the mother than the father (Pillard). Also, natural selection might maintain a gene that may decrease the fecundity of one sex because the same gene also increases the fecundity of the other sex. In fact, recent data shows that female maternal relatives of gay men have higher than average reproduction capacity (Camperio-Ciani).Another interesting result from previous research is that a male’s chance of homosexuality increases with the number of biological older brothers he has—even when he grows up away from his older male siblings (Blanchard and Bogaert). Scientists explain that, with each male fetus, a mother develops an increased immunization to an antigen produced by the male fetuses, and this antigen likely plays a role in masculinizing the brain.These studies and others—while unable to point to a specific gene—do point to the idea that homosexuality may be inherited through a polymorphic gene, which is a gene that has more than one different form, and can exhibit either form. Studies have shown that this gene inheritance must be more complex than for common Mendelian traits. To take the next step, Gavrilets and Rice have developed several mathematical models that make contrasting predictions for the possible factors responsible for the polymorphism of genes influencing homosexuality. Hopefully, the predictions generated by these models will guide future tests and help zone in on the correct genetic characteristics involved in sexual orientation. As Rice explains, past research has shown the complexity inherent in determining the cause(s) of homosexuality. “We know that homosexuality (gay or lesbian) can be caused by simple genetic changes in fruit flies, and since so many reproductive and neurological genes are shared by flies and humans, it seems highly likely that there are major genes influencing homosexuality in humans,” said Rice. “However, we also have firm evidence for a birth-order effect on male homosexuality, and discordance in the expression of homosexuality of identical twins, so clearly there is also an environmental influence on the trait.”Gavrilets and Rice identify two main factors that may explain the polymorphism of a gene (and how the gene spreads): overdominance and sexual antagonism. Overdominance refers to phenotypes that come from heterozygous genes, and the advantages promoting genetic variation. Sexual antagonistic traits are those that are advantageous in one sex, but may cause homosexuality in the other sex. For a variety of different gene inheritance patterns, the scientists provide mathematical models that require, in essence, that the benefits for one sex must outweigh the costs for the other sex.In their study, Gavrilets and Rice make predictions for the likelihood of certain types of genes (e.g. autosomal or sex-linked, recessive or dominant, with small or large effects) favoring either overdominance or sexual antagonism under different conditions. However, many possibilities remain, and research into each one will determine how well they satisfy the requirements provided in this study.“The research so far that I think is most illuminating on this topic are the studies showing that homosexuality can have a simple genetic foundation in fruit flies,” said Rice. “I think that it is too early to decide which of our models (or one yet to be formulated) is most feasible. However, based on the abundance of sexually antagonistic variation found in fruit flies, the sexually antagonistic variation seems like a probable candidate process leading to polymorphism for homosexuality.”Citation: Gavrilets, Sergey and Rice, William R. “Genetic models of homosexuality: generating testable predictions.” Proceedings of the Royal Society B (2006) 273, 3031-3038.By Lisa Zyga, Copyrght 2006 PhysOrg.com

(PhysOrg.com) — GPS has become such an integral part of the new technology in our lives that we really do not give it much of a thought. It gets us to our destination without getting lost. It helps the ambulance to find us when we dial 911 on our cell phones. It lets you become the mayor of your gym for all those check in’s. GPS System Could Start Failing by Next Year When you get down to it, all of that technology is powered by a set of 24 satellites, and most of them have been up there for quite some time. The time has come for an upgrade. The newest version of a GPS satellite is called the GPS IIF and it is enhanced with more than one new upgrade.The GPS IIF is expected to double the accuracy of GPS, which is just as good of news for fans of Foursquare as it is for the FAA. One has to wonder exactly what doubling that accuracy really means. Well, currently GPS can estimate your location to an area of about 20 feet. When the next generation satellites are in place, this location will be narrowed down to an area of two to three feet, making pinpointing locations less like a range, and more like the spot you are standing on.This enhancement means that the next generation of GPS technology may be able to work with augmented reality technology indoors. Imagine having a virtual docent at the Met, or a guide to help you around your new college campus. The possibilities with this level of accuracy are intriguing.Currently, only one of these satellites, the GPS IIF SV-1, is in orbit and fully operational since August 2010. The second GPS IIF satellite, SV-2 is planned to launch this year. Eventually 10 other units will join them, and that is when you can expect to see the upgrades.

New study suggests some ancient bite marks from crocs not stone tools Explore further Journal information: Royal Society Open Science More information: Torsten M. Scheyer et al. Trophic interactions between larger crocodylians and giant tortoises on Aldabra Atoll, Western Indian Ocean, during the Late Pleistocene, Royal Society Open Science (2018). DOI: 10.1098/rsos.171800AbstractToday, the UNESCO World Heritage Site of Aldabra Atoll is home to about 100 000 giant tortoises, Aldabrachelys gigantea, whose fossil record goes back to the Late Pleistocene. New Late Pleistocene fossils (age ca. 90–125 000 years) from the atoll revealed some appendicular bones and numerous shell fragments of giant tortoises and cranial and postcranial elements of crocodylians. Several tortoise bones show circular holes, pits and scratch marks that are interpreted as bite marks of crocodylians. The presence of a Late Pleistocene crocodylian species, Aldabrachampsus dilophus, has been known for some time, but the recently found crocodylian remains presented herein are distinctly larger than those previously described. This indicates the presence of at least some larger crocodylians, either of the same or of a different species, on the atoll. These larger crocodylians, likely the apex predators in the Aldabra ecosystem at the time, were well capable of inflicting damage on even very large giant tortoises. We thus propose an extinct predator–prey interaction between crocodylians and giant tortoises during the Late Pleistocene, when both groups were living sympatrically on Aldabra, and we discuss scenarios for the crocodylians directly attacking the tortoises or scavenging on recently deceased animals. © 2018 Phys.org Today, the giant tortoises that live on Aldabra Atoll pass their days relatively stress-free due to an absence of predators. Their thick, dome-shaped shells offer them a very secure defense against creatures that might seek to harm them. But their peaceful existence is also thanks to laws that ban humans from harming them, and perhaps events that led to the demise of crocodiles that were big enough to attack them.The researchers report that during a visit to the atoll, they found parts of giant fossilized tortoise shells with large tooth bite marks on them. More importantly, they also found a jawbone that had once belonged to a large ancient crocodilian—one that was bigger than those represented by previously found fossils. Testing showed that both fossils were from a time period approximately 90,000 to 125,000 years ago—putting them in the late Pleistocene. The size of the fossilized jawbone, the team concluded, suggested that the crocodile would have been larger than the others that had lived on the atoll, but smaller than modern Nile or saltwater crocodiles. They further estimated by examining the jawbone that the crocodile would have been approximately 11.5 feet long—big enough to tear limbs or a head from an exposed tortoise. The tortoise would have weighed approximately 550 pounds.The researchers suggest that the bite marks on the tortoise shell indicate one of two possible scenarios. In the first, the croc had hidden itself beneath the water and then pounced when it saw the tortoise stretch its neck out to get a drink of water. The other possibility was that the tortoise died from another cause and the crocodile left marks as it attempted to get at the remains inside the shell.
Designing light sails is a major engineering challenge, however, requiring conflicting features that sound nearly impossible: an ideal light sail should be several meters wide and mechanically robust enough to withstand intense radiation pressure, yet be merely 100 nanometers or so thick and weigh just a few grams. Further requirements arise from the mechanism by which light sails work. According to Maxwell’s equations, light has momentum and as a result can exert pressure on objects. However, light sails are not simply pushed by radiation pressure like a sailboat is pushed by the wind. Instead, the push results from the light sail reflecting the radiation. As a result, an optimal sail should reflect the majority of the radiation in the laser beam’s near-infrared spectrum, while simultaneously emitting radiation in the mid-infrared range for efficient radiative cooling.Nanophotonic sailsIn a new study published in Nano Letters, researchers Ognjen Ilic, Cora Went, and Harry Atwater at the California Institute of Technology, Pasadena, have shown that nanophotonic structures may have the potential to meet the stringent material requirements for light sails capable of traveling at relativistic speeds.Previous light sail designs have used materials such as ultrathin aluminum, various polymers, and carbon fiber. Unlike these materials, nanophotonic structures have the ability to manipulate light at subwavelength scales, giving them an advantage in addressing the simultaneous requirements of efficient propulsion (reflection) and thermal management (emission). As an example, the researchers showed that a two-layer stack of silicon and silica shows promise due to the combined properties of both materials. Whereas silicon has a large refractive index—which corresponds to efficient propulsion—but a poor cooling ability, silica has good radiative cooling properties but a smaller refractive index.In their paper, the researchers also proposed a new figure of merit that measures the trade-off between achieving a low sail mass and a high reflectivity. In the future, this concept will help to minimize constraints on the laser power and the size of the laser array. Background on light sailsAlthough conceptualized for nearly a century, only in the past few decades has technology caught up to scientists’ early visions of propelling a spacecraft with the pressure of light. Inspired by the way that the Sun’s radiation pushes a comet’s tail in the opposite direction, the earliest concepts were of solar sails that use the radiation pressure from sunlight rather than from lasers. The first solar sail was launched in 2010 by the Japan Aerospace Exploration Agency (JAXA) and successfully reached the orbit of Venus in six months, powered only by the radiation pressure of sunlight. Now researchers are working on designing solar sails capable of greater accelerations that are competitive with rocket acceleration, offering the possibility of launching spacecraft without the billion-dollar cost of conventional propellants.Although solar sails may achieve rocket-like speeds, sunlight radiation is relatively weak compared to a high-power laser array. As a result, a laser array offers the potential for much faster propulsion, up to relativistic speeds—but more work is needed before such laser-powered sails are demonstrated.

Traveling at these relativistic speeds, laser-powered light sails could reach our nearest neighboring star (other than the Sun), Alpha Centauri, or the nearest known potentially habitable planet, Proxima Centauri b, in about 20 years. Both objects are a little more than four light-years away.
This could have turned out to be a column full of raves and rants, but that was thankfully averted by more than a mile. So one super cold evening, I undertook the journey from Delhi to Gurgaon, to check out this new place which is very intriguingly called Spoonful of Soul. The twists and turns of roads took me through sleeping neighbourhoods and I finally arrived at what looked like a traveller’s inn of yore. As I walked into the cobbled courtyard, I could see restaurants and designer boutiques around me. What made it even more interesting was was that the only way to reach the restaurant was a glass lift — nothing extraordinary but nice nevertheless. Also Read – ‘Playing Jojo was emotionally exhausting’Spoonful of Soul has been designed more like a cafe and as I walked in, warm hues of blue and purple and pink greeted me. The furniture is cane and wood, with rattan sofas filling up the cosy corners. A lot of soul has indeed gone into the décor. The walls have scooped shelves which house crockery — adding a nice touch.The menu is a mix of Continental and Mediterranean and a board lists the Thai dishes of the day (you can also order Chinese). Though it has not opened very long back, the liquor license is already in place.But the alcohol list is not exhaustive and they would do well to add more brands. The restaurant has mostly the regular cocktails and some of the mocktails are quite good (though why the Peanut butter shake is listed as a mocktail is beyond comprehension). But among the mocktails, you can try the Virgin Cosmopolitan. Also Read – Leslie doing new comedy special with NetflixThe food is mostly good. I was quite impressed with the way the Awesome foursome — which comprises kebabs made from chicken, fish and prawns — was served on skewers. Though it was served overcooked and slightly burnt. I also liked the idea behind the Prawn and apple salad — chunks of apple served with bits of prawns. If you don’t have any problem eating bacon, the Saltimbocca (see recipe) is a must eat. Those with a sweet tooth, do not leave without gorging on the Sweet Zebra — a vanilla ice cream and Oreo biscuit sandwich. It is served slightly hard so that the ice cream doesn’t melt, but it is worth it.DETAILAt: Spoonful of Soul, 27 Nathupur Road, DLF Phase 3, Gurgaon Timings: Noon to 3.30 pm (lunch); 7 pm to 11.30 pm (dinner) Phone: 0124 30146022Meal for two: Rs 1,000 (without alcohol)

A big news day and pending work can only mean one thing, a very heavy and spicy lunch. That is exactly what we set out to do heading for West Bengal Bhavan.Delhi’s probashi Bengalis (non-residential bengali’s if you may) have always retreated to the comfort of Banga Bhavan (as it is better known) or the Ma Tara Hotel in CR Park to get a taste of home. Then there is always Oh! Calcutta and City of Joy in Alaknanda to offer a slightly better dining experience. Also Read – ‘Playing Jojo was emotionally exhausting’While Oh! Calcutta turns you off with the completely ludicrous prices, City of Joy offers a substantially better deal. But beating it all I comes Banga Bhavan, you can sit in the air-conditioned interiors and enjoy your fill of Bengali food along with very good service.The menu is a fish lover’s delight – right from the crabs and the prawns and the monsoon special Hilsa – you will instinctively reach out for a well made fish fry. We decided to take the path oft not taken and ordered Mutton Cutlets. We wanted to savour the fish later. The cutlets were quite good and while we debated whether we should order round two, the Prawn Kabiraji came in. Basically a prawn cutlet fried in a thick layer of eggs is quite heavy, but sadly we were left disappointed. The prawns were not marinated enough and the coating, which is supposed to be light and fluffy was very oily and heavy on the tongue. Also Read – Leslie doing new comedy special with NetflixThe Chicken Kosha did not do justice to the expectations we had off it and compared rather poorly to the fish. Both the Fish Kalia and the Ilish Bhapa were perfect to say the least. The fish was fresh and the gravy perfect, not to spicy but full of taste.The Ilish was a part of the special monsoon Hilsa festival that is on in the bhavan and might not be easily available throughout the year – but all other items on the menu are. Including the much loved Luchi and Alurdom. But as luck would have it – office calls! While all the items in the menu will not blow you away, they have their spectacular hits and more than anything – eating at Banga Bhavan is definite value for money. We are going back again for sure!

Evolution has trained our brain to expect calories or energy from sweet-tasting foods and that is why low-calorie cookies or diet drinks do not satisfy us, suggests a research.The results could explain why dieting may backfire, leading us to eat more until the body meets its energy needs.We may even have hormones that help the brian distinguish real sugar from artificial sweetener, the study published the journal Neuron, said.“We knew that the human brain could tell the difference between real and fake sugar, we just did not know how,” said first author Monica Dus, assistant professor at the University of Michigan in the US. Also Read – ‘Playing Jojo was emotionally exhausting’For the study, researchers deprived fruit flies of food for several hours and then gave them a choice between diet, non-nutritive sweeteners and real sugar.When the flies licked the real sugar, it activated a group of six neurons that released a hormone with receptors in the gut and brain.The hormone fuelled digestion and allowed the fly to lick more of the nutritious food.On the other hand, when the fly licked the diet sweetener, it never produced this hormone/digestive reaction because zero-calorie sweetener has no nutritional or energy value. Also Read – Leslie doing new comedy special with NetflixIn every case, the flies abandoned the artificial sweetener and chose the regular sugar because the starved flies needed the energy provided by the calories in the real sugar.From an evolutionary perspective, sweet taste means sugar (traditionally from fruit or high concentrate carbohydrates) and a subsequent big energy boost.“Fruit flies cannot call out for pizza – their brains expect calories if they eat something sweet, and that is why they chose the regular sugar,” said Dus. “Fruit flies and humans share about 75 percent of the same disease-causing genes.”If our brains work the same way, this helps explain why diet foods do not satiate or satisfy us, and we gain weight while dieting, Dus said.It is analogous to a person eating that entire sleeve of low-calorie cookies and the body telling her she is still hungry.She keeps snacking until she eats something with nutritional value that meets her energy needs, the study said.
