Culture “It is a great privilege to be featured on a coin, and I hope my father would be pleased to be alongside Sir Isaac Newton and Charles Darwin as scientists who have made it on to money,” Lucy Hawking said in a statement. In a video taken at the Mint, she comments on the design. “It’s a 2D surface that seems to have a 3D image on it,” Hawking notes. “It’s as though you could fall into the black hole.”Coin collector site Change Checker says Hawking will be one of only three people commemorated on a British coin within a year of dying, along with Winston Churchill and the Queen Mother.When Hawking was just 21, he was diagnosed with a form of amyotrophic lateral sclerosis known as Lou Gehrig’s disease that gradually paralyzed him. He used a wheelchair and spoke through a computer system operated with his cheek.Hawking is also in the running to appear on the British 50 pound note. £50 translates to about $64 US and AU$92. Comment The Mint revealed the coin late Monday. It features Hawking’s name and an image of a black hole, with Queen Elizabeth II on the reverse side.The Hawking coin as shown on the Royal Mint’s site. Royal Mint “Stephen Hawking made difficult subjects accessible, engaging and relatable and this is what I wanted to portray in my design,” coin designer Edwina Ellis said on the Royal Mint’s site. “I wanted to fit a big black hole on the tiny coin and wish he was still here chortling at the thought. I am sure he would have thought of ways to harness the shiny table of the coin too.”Those of us who don’t have a regular opportunity to handle British money can buy the coin online, but it’s not cheap. According to the Daily Mirror, the Mint is selling the coin for £10 ($13 US, AU$18) for a simple uncirculated version of the coin to £795 ($1,050 US, AU$1,485) for a gold version of the coin. (Or just find a British friend to get you one.)The coin’s release came two days before the one-year anniversary of Hawking’s death on March 14. The acclaimed scientist was 76 when he died in 2018.Hawking’s daughter, Lucy, and son Tim visited the Royal Mint to see the coin.

In the wake of the revelations, Disney suspended its advertising spending on YouTube, Bloomberg reported Wednesday. (Disney reps did not respond to requests for comment.) Other advertisers that have frozen their YouTube ad spending include Epic Games, maker of “Fortnite,” and Nestle U.S., per the report. McDonald’s also has pulled YouTube ad spending, according to a Wall Street Journal report.YouTube did not comment on advertisers suspending their spending. According to YouTube, after Watson posted his exposé, the service terminated over 400 accounts and channels that violated its policies, disabled comments on “tens of millions” of videos and also reported illegal activity to law-enforcement authorities.“Any content — including comments — that endangers minors is abhorrent, and we have clear policies prohibiting this on YouTube,” a YouTube rep said in a statement. “There’s more to be done, and we continue to work to improve and catch abuse more quickly.”According to Watson, videos in the “pedophile ring” had run ads from brands including McDonald’s, Lysol, Disney, Hershey Co.’s Reese’s, Purina, Grammarly, Ikea and GNC.It’s the latest in a string of “brand safety” scandals for YouTube involving ads served with inappropriate content. In the fall of 2017, YouTube was hit by a backlash over ads on videos that attracted child predators. Earlier that year, evidence that YouTube was placing ads against violent and extremist videos led to a broad boycott by hundreds of advertisers, including Procter & Gamble, AT&T, Dish Network and PepsiCo.AT&T only last month announced that it planned to resume buying ads on YouTube after almost a two-year hiatus, telling the New York Times that it had determined the platform had taken sufficient steps to make itself “brand safe.”In response to the advertiser pullouts in 2017, YouTube moved to tighten controls over how ads are served and set new restrictions on creator eligibility for revenue sharing. Some YouTubers complained of an “adpocalypse” that cut into their earnings after the changes. YouTube is facing yet another big advertiser backlash, with Disney, Epic Games and McDonald’s among the marketers said to have pulled their ad spending after the Google-owned video platform was accused of facilitating what a critic described as a “soft-core pedophilia ring.”Vlogger Matt Watson, in a Feb. 17 video on his YouTube channel MattsWhatItIs, showed how YouTube’s algorithms enabled a secret “wormhole” for pedophiles, who posted sexual comments on videos of young girls and identified sections of the videos where they were in compromising positions or suggestive poses. In some cases, users were trading child pornography in the comments section, he claimed.“How does this exist?” a visibly upset Watson railed in the video. “For me, I want nothing to do with this platform that’s supporting this s—… It’s disgusting.” Popular on Variety ×Actors Reveal Their Favorite Disney PrincessesSeveral actors, like Daisy Ridley, Awkwafina, Jeff Goldblum and Gina Rodriguez, reveal their favorite Disney princesses.

Close up of polyps are arrayed on a coral, waving their tentacles. There can be thousands of polyps on a single coral branch. Credit: Wikipedia Marine rainforests Known as the “rainforests of the sea,” coral reefs form some of the most diverse ecosystems on earth. Despite only covering 0.1 percent of the ocean’s surface, they provide a home for 25 percent of all maritime species, including fish, mollusks, and sponges. Coral reefs are actually deposits of calcium carbonate, the substance found in sea shells. The makeup of any coral reef is complex and consists of microscopic organisms called corals that live together in small colonies known as polyps. Polyps that contain “reef building” coral species are responsible for laying down the calcium carbonate that form the reefs. Corals live together with algae, and this relationship helps coral reefs survive. But when coral reefs experience stress, such as an increase in sea temperature, they sometimes expel the algae, which results in coral bleaching, a phenomenon in which the coral loses all its color, appearing completely white. This can result in the death of the reef. For example, in 2005, the US lost half of its coral reefs in the Caribbean to a massive bleaching event.It is already known that some corals are better than others at coping with stress. So Professor Stephen Palumbi and his colleagues at Stanford University in California set out to assess whether coral species have the ability to acclimate to warmer temperatures by increasing their thermal tolerance levels. Palumbi and his team completed their fieldwork on coral reefs in the U.S. National Park of American Samoa on Ofu Island. They concentrated on an important reef-building coral species. The corals were contained in two adjacent pools. In the first pool, water temperatures were more varied, reaching temperatures as high as 35°C. This was known as the highly variable pool. The second pool, known as the moderately variable pool, rarely experienced water temperatures of above 32°C. Coral transplant First, the researchers tested the photosynthesis rates of corals from both pools to compare how well they coped with high temperatures. They then transplanted coral colonies from the moderately variable pool to the highly variable pool to see if the coral would adapt to higher water temperatures. The transplanted corals were left to acclimate over the course of about two years, and were regularly tested for thermal tolerance over this time. The researchers conducted genetic analysis to see if there was any change in gene expression during this period that would result in higher thermal tolerance.It was found that corals in the highly variable pool were more tolerant of higher temperatures when compared to the corals in the moderately variable pool. But the most interesting finding involved the ability of the coral to acclimate to higher water temperatures. Dr Daniel Barshis, part of the team that completed the research, said: “The most important finding was that corals are capable of increasing their thermal tolerance limits substantially in just 12 to 18 months. This acclimation in upper tolerance limits correlates with changes in gene expression as well.” Real-world applications Barshis went on to say that this new knowledge should be integrated into models that predict the effects of global warming on coral reefs to help us understand how they will respond to rising sea temperatures in the future, he said: “This research provides some glimmer of hope that corals may have the ability to survive more than we’ve given them credit for, but only if we reduce the amount of current and future stresses.”This research also has many real-world applications that could help protect coral reefs from future climate change. Palumbi said, “It should be possible to use climate-resistant corals in transplant/restoration efforts in order to replant reefs with greater future resilience. This is one of the things we are doing this summer in a set of pilot projects in Samoa.” Citation: Coral reefs are better at coping with rising sea temperatures than we thought (2014, May 30) retrieved 18 August 2019 from https://phys.org/news/2014-05-coral-reefs-coping-sea-temperatures.html Journal information: Science More information: Mechanisms of reef coral resistance to future climate change, Science 23 May 2014: Vol. 344 no. 6186 pp. 895-898. DOI: 10.1126/science.1251336ABSTRACTReef corals are highly sensitive to heat, yet populations resistant to climate change have recently been identified. To determine the mechanisms of temperature tolerance, we reciprocally transplanted corals between reef sites experiencing distinct temperature regimes and tested subsequent physiological and gene expression profiles. Local acclimatization and fixed effects, such as adaptation, contributed about equally to heat tolerance and are reflected in patterns of gene expression. In less than 2 years, acclimatization achieves the same heat tolerance that we would expect from strong natural selection over many generations for these long-lived organisms. Our results show both short-term acclimatory and longer-term adaptive acquisition of climate resistance. Adding these adaptive abilities to ecosystem models is likely to slow predictions of demise for coral reef ecosystems. This document is subject to copyright.

(Phys.org) —Coral reefs are under threat from rising sea temperatures caused by global warming. But in a recent paper, published in Science, it was found that certain types of coral are able to adapt to tolerate higher sea temperatures by changing the genes they express. Scientists think this new discovery could be used to devise new ways of protecting coral reefs, as well as improving our predictions of how they will cope with climate change in the future. © 2014 Phys.org Explore further Some corals adjusting to rising ocean temperatures, research says
Celebrating the spirit of colour orange, Camera Unlimited has brought its new photography exhibition titled Tangerine Tales to the Capital. Orange colour is considered pious in many religions like saffron robes of Buddhist monks, vermilion tilak on the forehead of a sadhu, bright orange turban worn by Sikh devotees and these symbolic visuals which can be seen in every day life have been captured very creatively by the photographers.An eighth exhibition in the series, this is an effort to blend the work of established as well as upcoming photographers, showcasing their talents on a common platform. The exhibition features photographs by Ahmed Firoz, Ambika Sethi, Dinesh Sethi, Krishan Sharma, Lubna Sen, Marta Martinez, Nitin Arjun, Rajesh Ramakrishnan, Rohit Kumar, Shilpi Choudhuri, Shivani Punia and Shoba Jolly. Also Read – ‘Playing Jojo was emotionally exhausting’Each photographers has interpreted the theme in a different manner. From a peeling orange wall depicting disturbed calmness to the explosion of vibrant expressions and colours of festival Holi, from abstracts in still life to surreal frames in motion, sunrise to sunset, the contradictions in the photographs may be obvious yet they all are tied by the common thread of colour – orange.The colour orange means different things to each of us. For some it may be the burst of energy, the passion of a glowing fire, while some associate it with the calmness of a sadhu’s robe and symbol of the autumn leaves. All the photographs on display are printed on Canvas and are framed in an identical manner which ensures that each of the artwork stands out and mark it’s impression on visitors.When: Till 24 NovemberWhere: Arpana Caur Academy of Fine Arts & Literature
On what turned out to be a pretty bad day in office, five-time world champion Anand went down rather tamely in the second game on Sunday and now trails 0.5-1.5 in the 12-game match. Anand’s body language also suggested that the king is currently down especially in the light of the fact that the opening had gone quite well for the Indian ace in both the games. However, as was the case in the last world championship match, Carlsen tuned the position of both games to his liking after some time and while Anand salvaged a half point in the first game, in the second he never got a chance. Also Read – Khel Ratna for Deepa and Bajrang, Arjuna for JadejaAnand looked more tentative than Carlsen and it was hesitation that cost him dearly in the second game.To his credit, Carlsen was at his best and did what he has mastered against top class opponents. An innocuous opening reached a level middle game and then the complexities stared to burden Anand to the extent that he fumbled and produced a rare blunder. This was clearly caused by sustained pressure by the Norwegian.In the last world championship match, Anand had drawn four before losing the fifth game. Anand will have to not only stop further damage but also seek a quick cruise control to stage a comeback in the match. In the third game on Tuesday Anand will play with white pieces.

East Midlands and Network Rail have both confirmed. Trains can now call at the station. Trains are unable to stop at a town’s railway station this evening – for the second time in four days. A lighting problem at Kidsgrove railway station means trains are unable to stop there. So far East Midland trains and Northern Rail are both reported to be affected – with rail transport being arranged to the town from both Stoke-on-Trent and Macclesfield. There is no word yet on whether London Midland, the third company that serves Kidsgrove, is affected. Passengers travelling to the town are being advised to get off at Stoke-on-Trent station, where alternative transport is being arranged. The issue follows a similar incident affecting trains travelling to and from the station on Saturday evening. A spokesman for East Midlands Trains said: “Due to a problem with the station lighting at Kidsgrove, services between Derby and Crewe will not be calling there until further notice.

France Telecom-Orange has entered into a put and call option that will allow it to sell its 20% stake in Portuguese telco Sonaecom to majority owner Sonae.The call is exercisable by Sonae over the next 18 months and the put will be exercisable by France Telecom during the three months following this period. Both put and call are exercisable at the same price of €98.9 million, but the price could rise to up to €113.5 million if Sonaecom is involved in a transaction that sees further consolidation or restructuring of the Portuguese telecom market.In December, Portuguese pay TV leader Zon Multimédia signed an agreement that would see it merge Sonaecom’s telco unit Optimus into its business. The operator’s services include the Optimus Clix IPTV offering.This agreement is subject to the confirmation of the Portuguese Securities Commission.
