On Sunday, Jimmie Johnson of Hendrick Motorsports won the 2016 Ford EcoBoost 400 at the Homestead-Miami Speedway and his seventh NASCAR Sprint Cup Series championship. The title tied him with Richard Petty and Dale Earnhardt for the most in Cup Series history.

Although he qualified 14th, a ruling of illegal modifications to his car required him to start the race at the back of the field of 40 cars. Meanwhile, fellow Chase for the Sprint Cup contenders Kyle Busch, Carl Edwards and Joey Logano qualified 9th, 10th and 13th, respectively. Pole position winner Kevin Harvick led the first 31 laps; Kyle Larson led the race high of 132 laps. Despite his last-place start, Johnson was able to reach the top five in less than 50 laps. However, Johnson remained behind his three championship rivals.

The race featured seven caution periods, six different leaders and 20 lead changes. The first caution came when Ryan Blaney hit the wall on lap 28; he would be involved in another caution on lap 208. Jeffrey Earnhardt spun on lap 81, while the third caution of the night came for debris on lap 172.

On a restart with ten laps to go, Edwards collided with Logano while attempting to block him. The resulting crash collected Brad Keselowski, Ryan Newman, Kasey Kahne, Ty Dillon, Chase Elliott, Regan Smith and Martin Truex Jr., whose car caught fire after hitting Keselowski. Logano received minimal damage in the contact with Edwards and was able to continue.

With less than four laps left, Ricky Stenhouse Jr. hit the wall, resulting in an overtime finish, which extended the race length to 268 laps. Johnson took the lead from Larson with three laps to go and held on to win his 80th Cup race and the championship.

Johnson commented, “It’s just beyond words […] We just kept our heads in the game. Chad called a great strategy, made some great adjustments for the short runs. Luck came our way and we were able to win the race and win the championship.”

Larson finished second, followed by Harvick, Logano and Jamie McMurray. With his fourth-place finish, Logano finished second in the points standings with 5,037 points, three fewer than Johnson; Busch, sixth in this race, and Edwards, 34th, finished third and fourth in the standings with 5,035 and 5,007 points, respectively.

The championship was Johnson’s first since 2013, and at the age of 41, he became the youngest driver to win seven titles. Prior to 2013, he won five straight championships from 2006 to 2010.

The race also marked the final Cup start for three-time champion Tony Stewart, who finished 22nd. Stewart congratulated Johnson in victory lane and Johnson gave Stewart his helmet as a gift.

Israel has purchased two more Dolphin class submarines which have the capacity to carry nuclear warheads. Israel already has three older nuclear weapons-capable Dolphin submarines but the new Dolphins have propulsion systems that allow them to remain submerged for longer periods of time, according to the Jerusalem Post, making it harder for them to be tracked by satellite. Experts view the purchase as a clear signal to Iran that Israel can retaliate if subjected to a nuclear attack.

“The Iranians would be very foolish if they attacked Israel,” said Paul Beaver, a British based defence analyst, speaking to the Washington Post. According to Beaver, the submarines would provide Israel with both first strike and second strike capability.

Israel already has land-based nuclear-capable ballistic missiles in the form of the Jericho I and II missiles.

German officials confirm that the contracts for the new submarines was signed July 6. The Jerusalem Post reports that they will be operational shortly.

Israel has never confirmed nor denied that it has nuclear weapons but is believed to have the world’s sixth largest stockpile of the devices, with most outside estimates putting their stockpile in the low hundreds. Israel’s possession of nuclear arms has often been a locus of bitter controversy in the Middle East, especially among countries who believe that the world community, and especially the United States, is hypocritical in its tolerance of Israeli nuclear arms while decrying the efforts of other Middle Eastern nations to develop their own nuclear capabilities.

Meanwhile, the Jerusalem Post reports there is a growing mood among Israel’s defence establishment that the country will have to act independently to stop Iran from obtaining nuclear weapons as the United States is unlikely to do so.

“America is stuck in Iraq and cannot go after Iran militarily right now,” according to an unnamed official quoted by the paper.

A report by the US House of Representatives’ Intelligence Committee released on Wednesday asserts that if Iran arms itself with nuclear weapons, Israel would be pressed to respond militarily. “A nuclear armed Iran would likely exacerbate regional tensions. Israel would find it hard to live with a nuclear armed Iran and could take military action against Iranian nuclear facilities,” the report states. Iran has continually maintained that it seeks only to develop nuclear technology for the production of electrical power, though this has been disputed by many nations.

The United Nations Environment Programme (UNEP) has released a comprehensive report on the current state of the global environment. Climate change, food and water shortage and a decline in biodiversity threaten humanity’s survival, so urgent action is necessary, the report warns.

UNEP’s Global Environment Outlook: environment for development (GEO-4) report involved the work of about 390 experts in various fields from around the world.

While the GEO-4 report salutes some improvements, for example the increased public awareness of environmental issues and political interest, it also warns that “There are no major issues… for which the foreseeable trends are favourable.” Although the report sets out a gloomy scenario, its main aim is to call for action.

More than 50 programmers, scientists, students, hobbyists and fans of the A.L.I.C.E. chat robot gathered in Guildford, U.K. on Friday to celebrate the tenth birthday of the award winning A.I. On hand was the founder the Loebner Prize, an annual Turing Test, designed to pick out the world’s most human computer according to an experiment laid out by the famous British mathematician Alan Turing more then 50 years ago. Along with A.L.I.C.E.’s chief programmer Dr. Richard S. Wallace, two other Loebner prize winners, Robby Garner and this year’s winner, Rollo Carpenter, also gave presentations, as did other finalists.

The University of Surrey venue was chosen, according to Dr. Wallace, not only because it was outside the U.S. (A.L.I.C.E.’s birthday fell on the Thanksgiving Day weekend holiday there, so he expected few people would attend a conference in America), but also because of its recently erected statue of Alan Turing, who posed the famous A. I. experiment which inspired much of the work on bots like A.L.I.C.E. University of Surrey Digital World Research Centre organizers Lynn and David Hamill were pleased to host the event because it encourages multi-disciplinary interaction, and because of the Centre’s interest in interaction between humans and computers.

Dr. Wallace gave a keynote address outlining the history of A.L.I.C.E. and AIML. Many people commented on the fact the he seemed to have moved around a lot in the last ten years, having lived in New York, Pennsylvania, San Francisco, Maine, Amsterdam and Philadelphia, while working on the Alicebot project. The A.L.I.C.E. and AIML software is popular among chat robot enthusiats primarily because of its distribution under the GNU free software license. One of Dr. Wallace’s PowerPoint slides asked the question, “How do you make money from free software?” His answer: memberships, subscriptions, books, directories, syndicated ads, consulting, teaching, and something called the Superbot.

Rollo Carpenter gave a fascinating presentation on his learning bot Jabberwacky, reading from several sample conversations wherein the bot seemed amazingly humanlike. Unlike the free A.L.I.C.E. software, Carpenter uses a proprietary learning approach so that the bot actually mimics the personality of each individual chatter. The more people who chat with Jabberwacky, the better it becomes at this kind of mimicry.

In another interesting presentation, Dr. Hamill related present-day research on chat robots to earlier work on dialog analysis in telephone conversations. Phone calls have many similarities to the one-on-one chats that bots encounter on the web and in IM. Dr. Hamill also related our social expectations of bots to social class structure and how servants were expected to behave in Victorian England. He cited the famous Microsoft paperclip as the most egregius example of a bot that violated all the rules of a good servant’s behavior.

Bots have advanced a long way since philanthropist Hugh Loebner launched his controversial contest 15 years ago. His Turing Test contest, which offers an award of $100,000 for the first program to pass an “audio-visual” version of the game, also awards a bronze medal and $2000 every year for the “most human computer” according to a panel of judges. Huma Shah of the University of Westminster presented examples of bots used by large corporations to help sell furniture, provide the latest information about automotive products, and help customers open bank accounts. Several companies in the U.S. and Europe offer customized bot personalities for corporate web sites.

Even though Turing’s Test remains controversial, this group of enthusiastic developers seems determined to carry on the tradition and try to develop more and more human like chat bots. Hugh Loebner is dedicated to carry on his contest for the rest of his life, in spite of his critics. He hopes that a large enough constituency of winners will exist to keep the competition going well beyond his own lifetime. Dr. Wallace says, “Nobody has gotten rich from chat robots yet, but that doesn’t stop people from trying. There is such a thing as ‘bot fever’. For some people who meet a bot for the first time, it can pass the Turing Test for them, and they get very excited.”

A University of Calgary research team developed a new method for extracting carbon dioxide (CO₂) directly from the air — a fundamental shift in carbon capture technology enabling capture of the most common greenhouse gas from so-called diffuse sources like aircraft, trucks and automobiles that represent half of the greenhouse gases emitted globally.

Professor David Keith, Director of University of Calgary’s (UofC) Institute for Sustainable Energy, Environment and Economy (ISEEE) and a team of researchers from UofC’s Energy and Environmental Systems Group built and operated a prototype system this summer producing results that compared favourably with commercial carbon capture systems. Two ‘provisional’ patents have been filed on the technology but Keith warns there are still “many pitfalls along the path to commercialization.”

Using a process adapted from the pulp-and-paper industry that halves the cost of CO₂ air capture in their custom-built tower, Professor Keith and his team captured the equivalent of about 20 tonnes per year of CO₂ (approximately equal to the yearly output of one person in North America) directly from the air with less than 100 kilowatt-hours of electricity per tonne of carbon dioxide on a single square metre of scrubbing material.

“This means that if you used electricity from a coal-fired power plant, for every unit of electricity you used to operate the capture machine, you’d be capturing 10 times as much CO₂ as the power plant emitted making that much electricity,” explains Professor Keith.

A report co-authored by Keith in the American Chemical Society’s journal Environmental Science & Technology explains “nearly all current research on carbon capture and storage (CCS) focuses on capturing CO₂ from large, stationary sources such as power plants. Such plans usually entail separating CO₂ from flue gas, compressing it, and transporting it via pipeline to be [stored] underground.”

Using CO₂ air capture technology, “a company could, in principle, contract with an oil sands plant near Fort McMurray to remove CO₂ from the air and could build its air capture plant wherever it’s cheapest — China, for example — and the same amount of CO₂ would be removed,” says Professor Keith in a UofC press release.

“While it’s important to get started doing things we know how to do, like wind power, nuclear power, and ‘regular’ carbon capture and storage,” Professor Keith continues, “it’s also vital to start thinking about radical new ideas and approaches to solving this problem.”

ISEEE’s Executive Director David Layzell points out that “energy-efficient and cost-effective air capture could play a valuable role in complementing other approaches for reducing emissions from the transportation sector, such as biofuels or electric vehicles.”
