first_img(PhysOrg.com) — Researchers at the U.S. National Ignition Facility (NIF) report that they are growing ever closer to reaching the ignition point with their laser generated nuclear fusion project. The facility, part of the Lawrence Livermore National Laboratory has been doing research to find out if very high powered lasers could be used to create nuclear fusion that could then be used to drive steam turbines to make electricity. In related news, officials for UK companies AWE and the Rutherford Appleton Laboratory have announced that they are joining forces with the research team working on the NIF project, adding years of expertise in both nuclear fusion and laser technology. To achieve inertial confinement fusion, researchers at the NIF project shoot multiple (192) very high powered lasers at a single pellet comprised of the hydrogen isotope deuterium, which causes it to compress to a fraction of its original size and fuse into helium atoms -releasing neutrons. The neutrons could then, in theory, be used to heat water to drive steam turbines. The only problem is, thus far, the power consumed by the lasers (some shots use more power than the whole rest of the United States) exceeds the power produced by firing them at the pellet. But, that appears to be changing.At a meeting this past week, sponsored by London’s Royal Society, representatives from the US facility and its two new British partners met to announce the terms of agreement between them all. NIF Director Ed Moses told the group (according to the BBC) that one shot of the NIF recently produced, for just the tiniest fraction of a second, more power than all the rest of the world was consuming. And while that is certainly impressive, it’s still just a fraction of what is needed to achieve ignition; the point where a self-sustaining chain reaction occurs (required for energy gain). Moses added that he believes the group will achieve ignition within the next couple of years. Part of the reason for his optimism is the advances that have been made in high power laser diodes over the ten years since the NIF was first designed. Laser Bay 2, one of NIF’s two laser bays, was commissioned on July 31, 2007.

Just 1300 pounds of water, for example, could provide as much electricity as 2 million metric tons of coal. Explore further This document is subject to copyright.

first_img Citation: Best of Last Week – Light’s pushing pressure, the riddle of Somerton Man and maintaining muscle strength as we age (2015, June 8) retrieved 18 August 2019 from https://phys.org/news/2015-06-week-pressure-riddle-somerton-muscle.html © 2015 Phys.org In other intriguing news, after years of forensic investigation, Somerton Man’s identity remains a mystery, and now researchers have begun to apply modern techniques to solve the riddle of the man found dead on Adelaide’s Somerton Beach back in 1948, first by looking at the history and code and secondly via DNA, isotopes, and autopsy. The man’s body was found on the beach by two horseback riders, his unexplainable cause of death and piece of paper in his pocket with an apparent code written on it, caused a sensation at the time.In technology news, a combined team of researchers from several institutions in Japan announced that they had developed a solar cell that set a world record with a stabilized efficiency of 13.6%. Also, a company called Batteroo announced that it had developed the Batteriser, a $2.50 sleeve for ordinary batteries that is able to extend its life by 800 percent. Another team in Japan announced an amoeba-inspired computing system that outperforms conventional optimization methods—it is a new algorithm based on branching. Also in a bit of startling news, a team of researchers at the University of Iowa found evidence that suggests a certain kind of bacteria may cause type 2 diabetes—a simple staph infection caused the disease in rabbits. Also, another team found new evidence emerging on the origins of life—they were able to shed some light on the transition of amino acid building blocks into life that occurred four billion years ago.And finally, if you, like billions of people the world over, have been worried about growing feeble in your retirement years, you might be interested in knowing that a team of researchers has discovered a key to maintaining muscle strength while we age—it is a protein, apparently, that we tend to make less of as we age.

(Phys.org)—It was a very good week for physics as a team of researchers from China and Israel made the first observation of the pushing pressure of light—they were able to show the surface of a liquid bending inward when exposed to a wide beam of light in a large container. Also Texas Tech professor Bill Poirier suggested that the strange behavior of quantum particles may indicate the existence of other parallel universes—a theory he calls “Many Interacting Worlds.”center_img After years of forensic investigation, Somerton Man’s identity remains a mystery (Part 1: History and Code) (a) Minkowski’s momentum of light: the surface bulges out, indicating that light is pulling on the medium. This regime occurs when the light is not able to put the fluid in motion (the light is too focused or the container of fluid too shallow). (b) Abraham’s momentum of light: the surface bends inward, indicating a pushing force. This regime occurs when the light is able to move the fluid. In both figures, the surface deformations are exaggerated for making them visible. Credit: Zhang, et al. Explore furtherlast_img read more

History on your plate

first_imgThey call it Daniell’s Tavern and they dish out some of the best recipes from the east, north and south of India. Of course I did a double take and checked out the name again. There’s a story behind it, the Sr. Executive Vice President and General Manager, Vijay Wanchoo had told me in a conversation. Daniell’s has a menu that revisits India from the eyes of Thomas and William Daniells. The uncle and nephew team came to paint the rich culture of India’s locales in 1786, in the midst of colonial era to assist the expanding British Empire. While they painted, they also got the chance to enjoy the local cuisine which got recorded meticulously in their diaries. The menu at this restaurant is right off those pages. Also Read – ‘Playing Jojo was emotionally exhausting’The restaurant greets you with a wonderful sense of comfort. It feels like splendid home to us localites, but for the foreign clientele, which Chef de cuisine Ved Prakash tells us – is the major bulk of diners;  it is a beautiful mix and match of luxury and indigenous charm. From the fresh marigolds on the tables to the live kitchen and the paintings on the walls – the romance fuses with the food on the plate. In a fresh innitiative to celebrate all things Punjabi, Daniell’s Tavern cooked up a storm. Apart from their signature dishes like Azeezun’s Glory (Navrattan Khaas) and Merchant’s Bounty (Keerai Masial), they dished out delicacies like Bhatti da Murgh, Macchli Amritsari, Maa ki Dal and Paneer Lababdaar. Also Read – Leslie doing new comedy special with NetflixServed with Sadda Chawal and assorted Indian breads – ‘Punjab’ was quite a celebration. The Maa ki Dal was an absolute favourite. I do believe there is something eternally comforting about dal-chawal and no this isn’t the Bengali in me speaking! The Punjabi Meat Masala was perfectly done and that gets a thumbs up along with the Shamiana Prawns.The chef suggested the Tandoori Salmon (apparently a hit with foreigners) but it was turned down for the Macchli Amritsari – I was already bursting at the seams. Salmon is a very soft fish and it is almost a matter of mastery to not ruin it on the tandoor – definitely something to try the next time round.  With Hastings Choice (Matka Kulfi) to round it up – Daniell’s Tavern is not something you want to miss when you are at the Imperial. Pencil in a date soon! DETAILMeal for two: INR 4000 + taxes without alcoholTimings: 6:30pm to 11:45pmlast_img read more

first_imgDo you feel apprehensive about using frozen foods thinking they are not nutritious? Now put your doubts to rest about frozen food in cold storage.Frozen food brand McCain Foods India has elucidated on the IQF technology to help users get over their inhibitions, said a statement.There are 12 stages before a vegetable or fruit is frozen. First is the reception of the raw produce (actually a misnomer because the product which is perfectly ripe is brought to the factory for freezing).  Also Read – ‘Playing Jojo was emotionally exhausting’The other 11 stages are pneumatic cleaning, washing and de-stoning, visual inspection, trimming, shelling, sizing, pitting and skinning, blanching, cooling, sorting, individual quick freezing (IQF), grading, packing and storage. The IQF method of freezing ensures that the quality of the end product is much superior compared to other methods of food preservation like dehydration, canning or bottling as it does not lead to any loss of nutrients, flavours, colours, shape or texture. The process also results in a longer shelf life (up to 18 months), reduced thawing loss and no product deformation.last_img read more
