The advantage of the new Energy Smart compact fluorescent lamp (CFL) is that it offers CFL efficiency along with the more aesthetic pleasing appearance of a typical incandescent bulb. The new light has the same size and dimensions of an old 60-watt bulb, which may make it attractive for fixtures in which the bulb is visible, or possibly for inexpensive ceiling fixtures designed to clip on to round bulbs.”The all-glass design, which I said would be out next year, combines that T2 spiral fluorescent tube with an electronics package contained in the neck of the lamp,” John Strainic, GE global product general manager, explains in the video. “So that gives you the profile of an incandescent shape…so it’s like building a ship in a bottle.”Strainic said that some very leading-edge patents were used for the process of cutting and resealing the bulb. The final bulbs will be frosted white, so most likely the inner fluorescent spiral won’t be visible. GE plans to make the new bulb available on December 28 at Target, in January at selected Ace Hardware stores, and everywhere else (including Walmart) around Earth Day 2009 (April 22). via: Gizmodo© 2008 PhysOrg.com A video clip of General Electric’s new Energy Smart CFL bulb, containing a fluorescent bulb in an incandescent-shaped outer bulb.

Yahoo Meme In Brief: Yahoo! integrates ask and search sites This document is subject to copyright. Apart from any fair dealing for the purpose of private study or research, no part may be reproduced without the written permission. The content is provided for information purposes only. Explore further According to David Ruiz, a blogger, systems analyst and senior programmer in Brazil, Yahoo has released a Twitter clone called Yahoo Meme in Portuguese. The Yahoo Meme is by invitation only. David Ruiz received his invitation to the alpha-version of the Twitter-like social networking site. Interestingly, Yahoo Meme uses a dog instead of the familiar Twitter bird. Mr. Ruiz says the term “meme” is an adaptation of the scientific observations of Richard Dawkins in his book, “The Selfish Gene”. On the Internet, a “meme” is used to describe a sort of fever of popular content available to everyone. In the Yahoo sense of the term for its new social networking site, Yahoo Meme, it is a term which expresses the notion of free and expanded, within the context of the original idea. Simply put, Yahoo Meme is easy to access and easy to use. A click on the call, sign in and name your meme, attach your url, give a less than a 100 character description and you are Go. A screen lists all the meme images which allows users to verify who is meme-ing you. Users can post videos, images, music and text in the same way as Twitter. The search feature needs some tweaking, but it is pretty new.According to Ruiz, the Alph-phase is closed and he has only a few invites available for distribution. He distinguishes Twitter from Memes conceptually, saying memes is more like the “fever” of the moment. The actual differences between Twitter and Yahoo Memes may be a distinction without a difference. Except Yahoo Memes is in the Portuguese language.© 2009 PhysOrg.com Citation: Yahoo is Going Portuguese Hound to Outwit Twitter (2009, May 15) retrieved 18 August 2019 from https://phys.org/news/2009-05-yahoo-portuguese-hound-outwit-twitter.html Brazil, a Portuguese speaking country is the 10th largest economy in the world and Yahoo has decided to get in on the action by coming up with a clone Twitter. The economic down-turn has affected Brazil to some degree, but its Foreign Minister Guido Mantega has announced it is cautiously optimistic for a turn around at years end.

ATLAS preprint: arxiv.org/abs/1207.7214CMS preprint: arxiv.org/abs/1207.7235 Explore further Endgame for the Higgs Boson Journal information: arXiv More information: Citation: CERN teams post Higgs Boson papers – one ups its sigma level of certainty (2012, August 2) retrieved 18 August 2019 from https://phys.org/news/2012-08-cern-teams-higgs-boson-papers.html (Phys.org) — The two teams working (and causing headlines around the world) at the CERN Large Hadron Collider CMS and ATLAS, have both uploaded papers describing their work in searching for evidence of the particle that is believed to explain why matter sticks together, the elusive Higgs Boson, to the preprint server arXiv. In their paper, ATLAS has bumped up its sigma level of certainty from 5.0 to 5.9 while CMS has kept its level at the 4.9 to 5 range. The sigma levels are indicators physicists use to gauge how sure they are of their results. 5.0, for example indicates the researchers believe there is a five in ten million chance that the signals they’ve seen are due to something other than what they believe it to be; in this case, evidence of a Higgs boson. 5.9 would bump up the likelihood to two in a billion.It’s important to note that both teams are still calling what they’ve found to be something “Higgs like” rather than boasting of the discovery of the actual boson. This is because neither team has actually seen the boson, instead, they rely on measurements of particles that are thought to come into existence as a Higgs decays; according to theory, it’s only supposed to last for the tiniest fraction of a second, too little time to actually see or record it. It’s also important to note that the sigma numbers aren’t measurements of how certain the researchers are that what they’ve found is the Higgs, instead they are numbers that represent how certain the teams are of what they’ve measured. This means it’s possible that all their measurements and numbers are right, but whatever caused them to come about isn’t an actual Higgs, but something else that is both close to a Higgs and un-described in the Standard Model. There is no statistical number to demonstrate how sure they are of that.What this all means is that both teams, and most physicists who study such things, are pretty sure that the work at CERN has proven that the Higgs boson does indeed exist and that further study will one day allow for the removal of the Higgs-like tag. On the other hand, if it turns out that what the teams have been measuring is due to something else, well, that will mean having to edit the Standard Model, which is a description physicists have come up with to describe all of the ingredients at their most basic level, that make up everything that exists.

Expression patterns of cryptochrome genes in avian retina suggest involvement of Cry4 in light-dependent magnetoreception, Journal of The Royal Society Interface (2018). DOI: 10.1098/rsif.2018.0058AbstractThe light-dependent magnetic compass of birds provides orientation information about the spatial alignment of the geomagnetic field. It is proposed to be located in the avian retina, and be mediated by a light-induced, biochemical radical-pair mechanism involving cryptochromes as putative receptor molecules. At the same time, cryptochromes are known for their role in the negative feedback loop in the circadian clock. We measured gene expression of Cry1, Cry2 and Cry4 in the retina, muscle and brain of zebra finches over the circadian day to assess whether they showed any circadian rhythmicity. We hypothesized that retinal cryptochromes involved in magnetoreception should be expressed at a constant level over the circadian day, because birds use a light-dependent magnetic compass for orientation not only during migration, but also for spatial orientation tasks in their daily life. Cryptochromes serving in circadian tasks, on the other hand, are expected to be expressed in a rhythmic (circadian) pattern. Cry1 and Cry2 displayed a daily variation in the retina as expected for circadian clock genes, while Cry4 expressed at constant levels over time. We conclude that Cry4 is the most likely candidate magnetoreceptor of the light-dependent magnetic compass in birds. Journal information: Journal of the Royal Society Interface Credit: CC0 Public Domain Birds that are able to migrate great distances obviously have some form of navigation system—they stop at the same places and have very clear destinations in mind. But how do they do it? In recent years, some in the field believed it had to do with iron-rich cells in their beaks serving as mini-compasses, but this theory has had some problems, such as how the birds translate beak sensations to directional signals. In this new effort, the researchers suggest it is not the cells in the beak that are responsible, but a type of protein that exists in their eyes. The researchers came to this conclusion by studying the brains, muscles and eyes of zebra finches. More specifically, they studied Cry1, Cry2 and Cry4, proteins associated with the circadian clock. The researchers found that Cry1 and Cry2 levels tend to rise and fall throughout each day, but Cry4 remains constant, suggesting it has another purpose.The researchers chose to study these particular proteins because they are made of a type of molecule that sometimes has an odd number of electrons, leaving some unpaired, and thus sensitive to a magnetic field. They also found that Cry4 tends to exist in clusters in a part of the bird retina that tends to get a lot of light and which is sensitive to blue light—this is important because prior studies have shown that birds are only able to navigate when blue light is available. Taken together, the evidence suggests that the protein plays a strong role in navigation.The study does not prove that the Cry4 protein is the key to bird navigation, but it makes a strong case for it. Earlier this month, a Danish and German team of researchers studying robins found that Cry4 levels also remain constant each day, but rise during the migratory season. A team of researchers at Lund University has found evidence that suggests a certain protein plays a prominent role in bird navigation. They have published their findings in Journal of the Royal Society Interface.
Shrujan, a grass-root, craft-revival, and income-generation organization, established in 1969, organised the largest exhibition of Hand Embroidered Products from 05 July to 08 July in the Aga Khan Hall. The exhibition focused mainly on saris, shawls, and dupattas, among other garments. Besides displaying 16 different styles of Hand Embroidery, made by craftswomen from 10 communities of the Kutch region of Gujarat, the exhibition presented a whole new array of vibrant colours and high-quality fabric to enthral any person with an eye and appreciation for art, textile, or embroidery. Also Read – ‘Playing Jojo was emotionally exhausting’Hiral Dayal, Trustee Shrujan, said, ‘Each of the 16 hand-embroidery styles from this region resembles a piece of jewellery. More than 95% of our customers who appreciate the uniqueness of this art have placed great trust in us for delivery of the best-quality and highly durable hand-embroidered finished products.’ In addition to focusing on a new range of designs for saris, shawls, dupattas, and other garments, the exhibition showcased new styles of not only garments but also stitches. Visitors to the Shrujan Hand Embroidery Exhibition found an eclectic mix of traditional embroidery on contemporary apparels, including men’s kurtas as well as silk and woolen jackets. Also Read – Leslie doing new comedy special with Netflix The years of research on hand embroidery from Kutch and its communities was evident on the resplendent display of stitches and vibrant colors. Besides its classic range, the highlights of the event were colourful, embroidered Maheshwari dupattas and stoles; and tie-and-dye skirts and cholis. Hand-embroidered fabrics that 3,500 craftswomen living in 100 remote villages of Kutch have fashioned into high-quality products were appreciated by all. At its previous exhibition, Shrujan presented the first book and instructional film entitled Under the Embroidered Sky: the Embroidery of the Ahirs of Kutch, that showed the research work and documentation and filming of the embroidery styles of other communities. For countless generations, this craft had been passed on from the mother to the daughter. However, with the oral tradition of teaching and learning falling out of favor, exploration of other methods of safeguarding the wisdom of the craft has become imperative.

Kejriwal also referred to BJP MP Sakshi Maharaj’s controversial remarks where he asked Hindu women to have at least four children, saying that the BJP was “running after women”.“Before the election, BJP leaders promised to provide full safety and security to women, but after poll, this party is running after women. They are asking our women to give birth to four children. I ask them, whether our women are child bearing machines?,” he said.
