Hurtling back through time

first_img Cambridge schoolchildren sample zooarchaeology at Peabody Museum Just outside the high-tech setting of Harvard’s Biological Laboratories, students were engaged in a decidedly low-tech activity: throwing spears across the quad.A group of six were trying their hands at using an atlatl, an ancient spear-throwing device that by 10,000 B.C. had spread around the world, according to Andrew Majewski, education specialist for the Peabody Museum of Archaeology & Ethnology and the instructor of the Wintersession course.Simple in design and use, the atlatl is essentially a short stick, roughly 2 feet long, with a spur or hook on one end to hold the butt of a thin, light spear, sometimes fletched like an arrow and called a dart. During a talk in the Peabody Museum’s education classroom before students headed outside, Majewski explained that the atlatl — developed thousands of years before the bow and arrow — works by giving the thrower additional leverage that can greatly increase the force of the throw. Homing in on bones Related Humans hot, sweaty, natural-born runners Target practice with ‘atlatl’ transports students to ancient times Projectile learning Monday’s cool-weather marathon wouldn’t bring down game The advantage in range and velocity made a big difference to prehistoric hunters, Majewski said, allowing them to take aim at megafauna such as mammoths without having to get dangerously close.“It was as revolutionary a technology for these people as the computer is for us,” Majewski said. “It allowed people to hunt big game for the first time.”Students had to master the tricky balancing act involved in preparing for a throw, with the atlatl cocked aside their heads and a dart nocked onto the spur and balanced on top. The dart is held in place with a forefinger and thumb while the other three fingers grip the atlatl handle. During the throw, students had to release the two fingers and the dart at the right point while keeping hold of the atlatl.After the first tentative tosses — and with coaching and encouragement from Majewski — students gained confidence. Darts flew through the air and skipped over the hard ground, skittering into a snow bank.“What we’re doing now is considered experiential archaeology, understanding the lives of our forebears by trying their skills ourselves,” Majewski said.,The class, “Making and Using an Atlatl Spear-Thrower,” was suggested by Polly Hubbard, director of education for the Peabody and Semitic museums, both part of the Harvard Museums of Science & Culture. Hubbard noticed Majewski’s interest in atlatl technology and suggested he develop the course. The goal would be to give students a taste of archaeology and encourage them to think of the museums as a resource, whether for their studies or their personal interests.“I tremendously enjoyed putting together all the different components of this workshop,” Majewski said. “I’m trying to get others excited about what excites me.”Majewski also coached students through hours of making and decorating their own atlatls and darts, which included straightening dart shafts, fletching the darts with feathers and adding stone points, carving and attaching stone tuning weights to steady the atlatls before a throw, and decorating and sealing the wood.,Diana Gerberich, a senior social anthropology and archaeology concentrator, said she learned about atlatls in the classroom and was intrigued enough to search the web for more information. Her next idea was to give the device a try, for which she was grateful to work with an experienced guide.“It was a lot of fun, I was so glad to be actually able to do it,” Gerberich said. “It’s a lot of fun to try to go into other humans’ minds and try to figure out [what] they went through, what sort of behaviors they had to do to get the product they wanted. … You can get a deeper understanding of it because you’re actually doing it yourself.”last_img read more

‘Green Machine’ begin battle in Hong Kong today

first_imgIT’S ‘D-Day’ for the Green Machine, Guyana’s National Sevens Rugby team, as they embark on yet another ‘David versus Goliath’ journey.Guyana will feature once again at the IRB Hong Kong Sevens where they will attempt to show the rest of the world that they belong among the ‘big boys’ after dominating the Caribbean circuit.Ryan Gonsalves was named captain of the team, and will be joined by Claudius Butts, Richard Staglon, Ronald Mayers, Avery Corbin, Patrick King, Vallon Adams, Blaise Bailey, Rupert Giles, Rickford Cummings, Peabo Hamilton and Rondell McArthur.Robby Roberts will serve as the team’s manager and Barrington Brown their physical trainer.Guyana were placed in Pool G, alongside Spain, Uruguay and Papua New Guinea. The ‘Green Machine’ as they are more popularly known, will open their account on April 7 against Spain and would wrap up day one of the tournament facing the team from Southwest of the Pacific Ocean (Papua New Guinea).Guyana’s 7s rugby team captain Ryan GonsalvesThe men from the Land of Many Waters will play their South American neighbours Uruguay on April 8 in their final Group stage game.Green Machine head coach Shane Grant-Stewart is of the opinion that his team, collectively, are on-par with several of the world’s top rugby-playing nations, but more exposure at the top level is much needed.Meanwhile, for Gonsalves, it will be a return to familiar territory, with the team’s captain highlighting, “This is no strange place for me, and for some of the guys on the team. We all know what it takes to excel in Hong Kong. It’s no easy place because those teams are more regularly invited to the Sevens circuit when we (Guyana) have to wait an entire year to play and we have to actually qualify.”“It’s going to be tough, so we’re going to see how much practice games we could get with teams out of our group and we’ll try to get up with the speed of the game because that’s one factor that works against us.“Our chances are good and despite our showing the last time, we’re going out there to show that we belong at the top level and we’re not an underdog team,” Gonsalves added.last_img read more

Donegal teacher teams up with Bia le Beatha for voluntary trip to Uganda

first_imgKincasslagh woman Eimear Logue has teamed up with Bia le Beatha (Food for Life) and is set to travel to Uganda on a voluntary trip this summer.Bia le Beatha was established in conjunction with the Irish charity, Nurture Africa, which aims to empower children in Uganda.A maths teacher at Errigal college, Eimear will teach at Kasengejje Primary School in Uganda, which has 550 students. The students at Errigal College are being a fantastic help to Eimear for her upcoming fundraising events.The goal of Eimear’s trip is to provide 550 students with two meals a day to maximise their educational experience, and to assist locals in setting up farms so as they can cultivate their own crops.Speaking to Donegal Woman, Eimear said; “Bia le Beatha was set up by a friend of mine, I loved the idea and really wanted to get involved. “The aim is to provide the 550 school children with two meals per day. This is year one of the project.“The plan is to buy land and crops so that the school can be self sufficient in the next two years. This year we will provide them with enough food for the year until the crops grow.“Errigal College have been a great help, both the teachers and students are working very hard to raise funds for the project. The plan is to link in with Agricultural students and secondary school students next year through Developmental Education so that the project can provide for more schools in Uganda.There are several fundraisers coming up to help Eimear make a difference in the childrens’ lives.On Easter Sunday, there will be a coffee morning and bake sale at St. Mary’s Hall in Kincasslagh between 11am and 1pm.On Easter Monday a table quiz will take place at Carey’s Viking House at 9:30pm. A ‘Cycle to Africa’ will be completed in Letterkenny Shopping Centre on Thursday the 27th between 10am and 6pm, involving Errigal College students.On April the 29th, ‘The Kube’ will be hosted at the Westmanstown Conference Centre in Dublin, costing only €20 to enter with the chance of winning €1,000!All proceeds go directly to Bia le Beatha.All of these events are crucial in being able to provide the nutrition necessary for the children.

Artificial intelligence to fuel a new cybersecurity race say experts

first_imgMONTREAL – Technological advances in artificial intelligence are fuelling a new race between hackers and those toiling to protect cybersecurity networks.Cybersecurity is always a race between offence and defence but new tools are giving companies that employ them a leg up on those trying to steal their data.Whereas past responses to cybercrimes often looked for known hacking methods long after they occurred, AI techniques using machine learning scan huge volumes of data to detect patterns of abnormal behaviour that are imperceptible to humans.Experts expect machines will become so sophisticated that they’ll develop answers to questions that humans won’t clearly understand.David Decary-Hetu, assistant professor of criminology at the University of Montreal, says defenders have an edge right now in using artificial intelligence.“But who knows what’s going to happen in a few years from now,” he said in an interview.“The main issue is that if you’re defending a system you have to be good 100 per cent of the time, but when you’re attacking the system you only have to be successful once to get in.”Decary-Hetu said a growing list of corporate and government officials, including Bank of Canada governor Stephen Poloz, who say infiltrations are their top worry have a very good reason to fear.The Bank of Canada warned in its semi-annual review released this month that the high degree of interconnectedness among Canadian financial institutions means any successful cyberattack could spread widely throughout the financial system.Reports suggest cybercrime costs the Canadian economy between $3 billion and $5 billion a year, including ransom paid to foreign criminals.Hacks of Sony Pictures, Uber, Ashley Madison, Yahoo and multinational retailers have sparked unsettling headlines about security of personal information.One of the latest to face scrutiny is global credit-reporting firm Equifax. Hackers accessed the personal information, including names, social insurance and credit card numbers, as well as usernames, passwords and secret question/secret answer data of 19,000 Canadians and 145.5 million Americans.Current detection systems tend to only recognize improper activity based on past events, often long after the damage is done.An example of this is Equifax, which discovered the breach in July, months after hackers first infiltrated the system. It only notified the public in early September.Niranjan Mayya, founder and CEO of Toronto-based Rank Software, said it takes on average 143 days for a breach to be detected.The challenge is growing as the number of connected devices in the world continues to soar.“Clearly the old style techniques of looking at cybersecurity threats and having people go through each threat aren’t working anymore, so automated means of detecting threats has become more and more important,” he said.David Masson, Canadian manager for U.K.-based Darktrace, said artificial intelligence will help to keep up with threats by quickly identifying and stopping attacks by picking up on subtle markers that identify bad behaviour.He said his company’s systems map a customer’s entire network, including every user and device, to discern even the slightest deviations as they emerge.Masson said AI is needed to keep up with threats by automating defence responses to growing machine-on-machine attacks launched by sophisticated hackers.“You’re kind of looking at a cyber arms race,” he said in an interview.“If you want to keep up with this threat and put the advantage back in the hands of the defenders you’re gonna have to use AI.”Ontario-based utilities company Energy+ Inc. said installed Darktrace technology alerted it to a user going to a malware site in Russia and uploading undisclosed sensitive data to a third-party cloud provider that its existing security was unable to catch.Some observers temper the current exuberance about AI, saying it’s not a silver bullet and these are nascent days for the technology.Receptiviti CEO Jonathan Kreindler says the hype around artificial intelligence has accelerated and has almost become a branding exercise for some companies that aren’t even offering truly leading edge technology.“The term AI is now being applied to any sort of algorithmic reasoning unfortunately,” said Kreindler.His firm uses AI to scour writings for unconscious use of language to understand the psychological state of company insiders who are responsible for 80 per cent of cybersecurity issues.Canada’s largest IT company, CGI Group, said artificial intelligence is a growing field of interest for customers, although the average client is in the fairly early stages of considering AI adoption in cybersecurity.CGI cybersecurity expert Andrew Rogoyski said that still puts them one step ahead of most hackers, who are typically interested in stealing data using the cheapest tools possible.Rogoyski added that he expects a strengthening of defensive mechanisms might force hackers to also adopt innovative techniques such as AI.“There’s a race, it’s been going on for 20 years plus and the race just keeps evolving. We keep leapfrogging each other,” he said.last_img read more

Settlement reached in Giants Manning memorabilia fraud case

first_imgHACKENSACK, N.J. – Three sports memorabilia collectors who accused New York Giants quarterback Eli Manning of providing bogus “game-worn” equipment that was sold to unsuspecting fans settled their lawsuit against the Super Bowl-winning quarterback on Monday, days before the case was scheduled to go to trial.A spokesman for the defendants, a group that included Manning, the Giants, two equipment managers and Steiner Sports, the company with whom Manning is under contract to provide game-worn jerseys and helmets for sale, said Monday night a settlement had been reached to resolve the claims. Details were not given.Plaintiffs Eric Inselberg, Michael Jakab and Sean Godown had sought triple the amount of their alleged losses — which totalled less than $20,000 combined — for buying two helmets billed as worn by Manning. They also had sought punitive damages, and claimed in court filings they would produce evidence that would “show that Manning engaged in a pattern of knowingly providing items to Steiner Sports that he misrepresented as having been game-used when he knew they were not.”Manning and the Giants had denied the allegations and characterized the suit as “inflammatory and baseless” in court filings.Jury selection was to have begun this week, but a death in the family of one of the attorneys had pushed that back to next Monday.An attorney for the plaintiffs confirmed the settlement Monday night.Inselberg filed the lawsuit in 2014. The suit claimed two helmets purchased by Inselberg and the two other plaintiffs — including one purportedly used by Manning during the Giants’ 2007-2008 Super Bowl season — were bogus. Inselberg alleged photographic experts using a technique called “photomatching” could not find evidence that the helmets were ever used in games.The Giants and Manning contend photomatching is unreliable because it does not take into account that helmets are routinely reconditioned during or after a season, the evidence of which might be found on the inside of the helmet and not the outside.The stakes were raised in the lawsuit in April 2017 when Inselberg’s attorneys filed court documents that contained emails between Manning and equipment manager Joseph Skiba, who also was a defendant in the lawsuit. In one email, Manning asks Skiba to get “2 helmets that can pass as game used.”The email does not refer to the two helmets at issue in the lawsuit, but Inselberg alleged it indicates a pattern of fraud.When the emails went public last year, Manning angrily denied any wrongdoing. In a court filing this month, Manning’s attorney wrote that the email was intended to ask Skiba for two game-used helmets that would “satisfy the requirement of being game-used.”“Manning never instructed Joe Skiba to create any fraudulent memorabilia,” attorney Robert Lawrence wrote. “Rather, Manning believed that if he asked Joe Skiba for his helmets, he received his game-used helmets and that the helmets he received from Skiba were his game-used helmets.”In the same court filing, Manning’s lawyer accused Inselberg of being “engaged in a decades-long memorabilia scheme” in which he obtained, without permission, game-used Giants equipment, including Manning’s, from Skiba and Skiba’s brother, Ed, as well as a local dry cleaner.last_img read more

Report Uber IPO could put company value at 120 billion

first_imgNEW YORK, N.Y. – Uber may put forth an initial public offering early next year that values the ride-hailing business at as much as $120 billion, according to a media report.The Wall Street Journal said Tuesday that Uber Technologies Inc. received valuation proposals from Goldman Sachs and Morgan Stanley. There is no guarantee Uber will fetch that valuation, or go public soon.If it does, and at that price, the company would be worth more than Ford Motor Co., General Motors Co. and Fiat Chrysler Automobiles combined.There are hurdles for Uber, past and present. In addition to a series of scandals including workplace sexual harassment, theft of intellectual property and the ouster of its co-founder, the company is facing increasing competition.The Journal also reported Tuesday that Uber’s smaller, but chief rival, Lyft, had picked underwriters for a public offering expected in early 2019. JPMorgan Chase & Co. will lead the offering, along with Credit Suisse Group AG and Jefferies Group LLC, the Journal reported. Lyft was valued at $15.1 billion earlier this year.last_img read more
