Buffs, Booker end #6 KU’s 19-game win streak
Dec 8th
BOULDER – No way for Colorado to beat towering, talented Kansas without 6-9 forward Wes Gordon?
Way.
No way (except maybe at gunpoint) that CU coach Tad Boyle strays from man-to-man defense and utilizes a 2-3 zone?
Way.
No way Coors Events Center matinee idol Ben Mills contributes meaningful first-half minutes against a team like the Jayhawks?
Way.
No way CU shoots nearly as frigid as the Boulder weather – 41.1 percent from the field and 59.5 percent from the foul line – and survives?
Way.
And no way the up, down, often kicked-around Askia Booker delivers the biggest shot of his life?
Way – and way, way past that.
It was CU 75, No. 6 KU 72 at the sold-out, geeked-out CEC on Saturday afternoon. The Buffs (9-1) won their ninth consecutive game for the first time since the 2005-06 season and slapped down a top 10 team for the first time since last Valentine’s Day when they beat No. 9 Arizona 71-58.
But that win won’t hold a holiday candle to this one. Christmas morning in the Rocky Mountains might not be able to match this – at least not for Boyle, his Buffs basketball program and an adoring CU fan base.
Booker hit three-pointers to close out each half, but it was his 30-footer at the final buzzer that he, his teammates and the crowd of 11,113 will remember for . . . maybe forever.
It had been a decade – or since the 2002-03 season – and 19 games, most of them in another conference, since CU defeated KU, and it was Boyle’s first win as a head coach in five tries against his alma mater. The Jayhawks still lead the series 123-40, but as for that 40th Buffs win . . .
“I’m not quite sure what to say after that one . . . it’s hard to put in historical perspective,” Boyle said about half an hour after CU students had cleared the CEC court and the building had stopped shuddering. “It was a hump game for our basketball program, considering what they did to us last year at Allen Field House and the amount of talent they have on their team.”
“Last year” was a 90-54 beat down in Lawrence, and if Booker and the Buffs said it didn’t motivate them, there will switches and ashes in their stockings in about three weeks.
CU’s list of Saturday heroes starts with the 6-1 junior guard from Los Angeles but goes upward to the 7-0 Mills, who means every bit as much to his teammates as the Buffs logo. Then add Spencer Dinwiddie (15 points, seven assists), Xavier Johnson (14 points, six rebounds, three steals), Josh Scott (14 points, four boards, two assists) and nearly every other CU player who suited up.
But it was Booker’s final trey that shot down the Jayhawks and shut down their fans. With 3 seconds to play and the score tied at 72-72 after KU had erased a nine-point CU lead, Booker got a pressurized inbounds pass from Johnson at the right sidecourt, went three dribbles past halfcourt and pulled up for more of a one-handed push shot than a jumper.
The ball found the net as time expired and Booker, who tied Dinwiddie with a team-best 15 points, found his place in CU hoops history. Was it the biggest shot of his career?
“Without a doubt . . . unless I win an NBA championship, that’s it,” he said. “I’m not sure I ever thought that would happen. At the same time, I think it’s a testament to Coach Boyle and how we go through our late clock plays in practice. The reason he does that is for nights like this.
“Thankfully, I came out and hit that shot. It felt great when it left my hand. I told the media after the game, I was actually in a straight line, which is great for a shooter. You don’t want to be fading away to the left or the right or backwards. I was going straight for the basket. My momentum held my form up and it went right in.”
Said Boyle: “When he let it go I knew it was in . . . it was money.”
Kansas (6-2) might have believed it would cash in inside with the absence of Gordon, who had missed practice since CU’s Tuesday night win at Colorado State due to illness/injury. The Jayhawks usually thrive inside with 7-0 Joel Embiid, 6-9 Tarik Black and 6-8 Perry Ellis, and they did outrebound the Buffs 33-32 and got 10 points each from Embiid and Ellis.
KU didn’t lose much of its power inside, outscoring CU 42-26 in the paint. The Jayhawks also got 22 bench points to the Buffs’ 14, but CU converted 14 KU turnovers into 24 points. The Buffs committed eight turnovers – a monstrous improvement from last season in Lawrence when CU had 12 by halftime and 18 by game’s end.
In the rematch, with Gordon watching from the bench in street clothes, Boyle knew a step up was needed from his frontcourt players such as the 6-7 Johnson, 6-10 Josh Scott and reserves such as Mills, who contributed eight of his 10 minutes and all of his four points in the first half. Mills also snatched three rebounds.
“It was so much fun,” Mills said. “This is something you dream of as a kid, a packed house at the Coors Events Center and the fans going nuts. To come in and play well in front of the fans and put on a show for them was great.”
Trailing by as many nine twice in the first 20 minutes, the Buffs finally caught the Jayhawks with a 14-4 run and took their first lead (26-25) on a layup from the left side by Mills with 4:21 left before intermission. It was Mills’ second straight basket, following a pump fake that got Embiid in the air and resulted in a soft, short jumper.
The CEC crowd roared with both of Mills’ baskets – and more of the blissful noise for the Buffs was coming.
Said Booker of Mills: “This guy comes to practice every day and works his butt off. Although he may not play as much as he wants or as much as he should, when his number was called, he was ready. Without him, we wouldn’t have won the game.”
And Boyle said the game wouldn’t have been won if he hadn’t “swallowed my pride,” pulled the Buffs out of his favored man-to-man and stationed them in a 2-3 zone. Given Gordon’s day-to-day status and KU’s inside power, Boyle said he had no choice: “If they would have made some shots against it in the first half early I probably would have gotten out of it, because I’m not committed to it. But, they didn’t, they struggled with it, and so we stayed with it. Second half we tried to flash it and keep them off balance a little bit. It’s hard sometimes man to man once they get in a rhythm to stop them, and I think the zone helped keep them off balance.”
Also, the Jayhawks came to Boulder shooting 30.7 percent from three-point range, and part of Boyle’s strategy was to make them jump shooters rather than layup and put-back artists. KU finished at 52.9 percent from the field (25 percent from beyond the arc) and Boyle conceded on first glance at the stat sheet, “I wonder how we won . . . but our guys’ resiliency and guts won out. I’m just glad we had the ball at the end; they were scoring pretty quick, pretty easily at the end.”
The Buffs endured their worst free-throw shooting of the season in the first half, hitting only 11 of 19 and finishing 22-for-37. In the final 1:49, Dinwiddie hit five of six and Booker one of two – his make coming with 12.8 seconds to play. KU called timeout with 11 seconds left to reset, and Ellis tied it at 72-72 with a layup.
The Jayhawks had rallied from nine down after the Buffs went up 53-44 on one of two free throws by Tre’Shaun Fletcher and a steal and stuff by the freshman on the next KU possession. But over the next 2 minutes, a 7-0 Jayhawks run cut their deficit to 53-51 and it was Boyle’s turn to call a timeout with just over 9 minutes to play. When the Buffs didn’t score, super KU freshman Andrew Wiggins (22 points) sent KU’s run to 9-0, tying the game at 53-53 with a layup at the 8:38 mark.
CU led by as many as six points twice in the final 3:36, the first six-point lead (63-57) coming on a Booker trey from the right corner. That shot, said Booker, “was great for me, but at the same time that play was initially for Spencer. I think they expected that so they left me open . . . it let me make the play.”
But the Jayhawks weren’t waving a white towel. They roared back behind a trey and two-pointer by Naadir Tharpe, a Wiggins layup and an Ellis tip to close to 70-68. With 12.8 seconds showing, Dinwiddie caught Wiggins’ elbow on a three-point attempt, and Wiggins hit two of three free throws to pull KU to within 71-70.
Dinwiddie made one of two foul shots – he finished eight-for-10 from the line – to increase the Buffs’ lead to 72-70. But Ellis’ layup tied the score and set the stage for Booker’s buzzer beater and the CU students storming the court.
Boyle said Booker, who was just five of 24 from three-point range in the first nine games but three-for-six Saturday, “is important to us, he’s our emotional leader. He can’t let his play affect his leadership on the court and it’s hard, it’s hard when you’re a shooter and you’re not shooting it well . . . (but) the capability’s there. If I didn’t see it in practice and he’s shooting that percentage (20.8 percent on three’s through nine games), then I’m the dumbest coach in America to be playing him.”
Turns out Boyle isn’t close to dumb or dumber. “Ski” Booker chiseled out his place in Buffs history and KU fans left the CEC without chanting “Rock Chalk Jayhawk.”
Said Boyle: “’Ski’ made an unbelievable play and we’re going to take it and not look back. Our crowd was great; to me it was a great day for college basketball in the state of Colorado and I’m really proud of our guys.”
CU: Build your own 3-D video game
Dec 5th
you build a video game, learn to code
In just one hour, school kids, teachers and any code-curious member of the public with an Internet connection can now create their own 3-D video game using a tutorial built by a team at the University of Colorado Boulder in preparation for the global “Hour of Code” event happening the second week of December.
CU-Boulder’s game-building program allows people with zero experience coding to design their own 3-D worlds by “inflating” hand-drawn 2-D icons and then programming those objects to interact in defined ways. For example, a participant could easily create a 3-D version of the classic arcade game Frogger by inflating a frog and then writing a line of code that would tell the program to squash the frog if it collides with a truck that has also been programmed to move horizontally across the screen at a set speed.
CU-Boulder’s online game-building tool is among a variety of self-guided tutorials that have been created for the Hour of Code, an event that aims to recruit 10 million schoolchildren to spend one hour during the week of Dec. 9-15, dubbed Computer Science Education Week, learning the basics of coding. The event, spearheaded by the nonprofit code.org, is designed to spark excitement about coding among youth in order to bolster a future interest in computer science, a field that’s increasingly important to a wide range of careers as well as everyday life.
“Programming should be easy and exciting,” said CU-Boulder computer science Professor Alexander Repenning, who led the project. “But that’s not where we are. The perception of the public is that it’s hard and boring. Our goal is to expose a much larger as well as broader audience to programming by reinventing computer science education in public schools.”
CU-Boulder’s Hour of Code tutorial—which can be found at http://hourofcode.com/ac—builds on two decades of Repenning’s research, which has pioneered drag-and-drop programming tools for kids called AgentSheets and AgentCubes. Repenning and his team also have developed Scalable Game Design, a curriculum teachers can implement to help their students use AgentSheets and AgentCubes to learn computer science through building their own video games.
Students can use the same tools and their new computational thinking skills to build science simulations—the coding needed to lay out what should happen when a truck collides with a frog is not that different from the coding needed to outline the chemical reaction that occurs when two molecules collide, for example.
The Scalable Game Design project recently received a $2 million grant from the National Science Foundation to continue to expand nationally.
From the beginning, the purpose of Scalable Game Design was to give school kids a taste of coding that might be able to flip the often-held belief that computer programming was not something they wanted to learn.
Repenning and his team began to reach out to kids in the local Boulder Valley School District, offering video game-building workshops as an after-school activity. The participants loved it, but the kids who initially showed up were the usual suspects—boys. In subsequent years, the project was introduced into classes that were already being taught during the school day, exposing all kinds of kids who might not normally be inclined to try computer programming, especially girls and minority students, to code.
“We asked them after, ‘Did you enjoy the activity?’ And they said, ‘Yeah. We love it and we want to do more of it,’ ” Repenning said.
The program is now ubiquitous in Boulder-area middle schools, and beginning about five years ago, Repenning received a $1.5 million grant from NSF to expand the program to schools outside the local district, especially districts with widely varying demographics, from inner-city schools to extremely rural schools and Native American communities. To implement the expansion, CU-Boulder hosted trainings on campus each summer to prepare teachers to deliver the program.
During the first expansion, Repenning and his colleagues also discovered that the way the video-game curriculum was taught impacted the degree to which girls, who are vastly underrepresented in computer science, were interested in coding. Direct instruction appeared to turn girls off, while inquiry-based approaches got the girls as excited as the boys.
Repenning has since received two more NSF grants. The first, for $1.5 million, is being used to follow up on how pedagogy affects girls studying computer science. The second and most recent grant—$2 million awarded in August—recognizes the achievements of the initial expansion effort and is being used to further spread Scalable Game Design across the country.
After the initial expansion, the Scalable Game Design team measured the success of the program by gauging the interest students had in learning more about computer science after they finished designing a video game and by analyzing the games themselves to see if the design of the games demonstrated a grasp of coding concepts. With positive results in both categories, NSF gave the team a green light to further expand the program by offering some teacher-training programs online.
The Hour of Code tutorial built on the Scalable Game Design infrastructure now allows anyone who is interested to get a taste of video game programming.

CU study: Some primates sleep in caves for safety
Dec 4th
The ring-tailed lemurs may be opting to sleep in caves for several reasons, said University of Colorado Boulder anthropology Associate Professor Michelle Sauther, who led the study. While the cave-sleeping behavior is likely important because it provides safety from potential predators, it also can provide the primates with access to water and nutrients, help to regulate their body temperatures during cold or hot weather and provide refuge from encroaching human activities like deforestation, she said.
“The remarkable thing about our study was that over a six-year period, the same troops of ring-tailed lemurs used the same sleeping caves on a regular, daily basis,” she said. “What we are seeing is a consistent, habitual use of caves as sleeping sites by these primates, a wonderful behavioral adaptation we had not known about before.”
A paper on the subject appeared in the November issue of the journal Madagascar Conservation and Development. Funding for the project came from Primate Conservation Inc., the International Primate Society, the American Society of Primatologists, the National Geographic Society, CU-Boulder, the University of North Dakota, Colorado College and the National Science Foundation.
Although sleeping in caves by ring-tailed lemurs — which are found only in Madagascar — has likely been going on for millennia, it is only now being recognized as a regular behavior, said Sauther. The endangered Fusui langurs, slender, long-tailed Asian monkeys roughly 2 feet tall, also have been documented sleeping in caves but as a direct result of extreme deforestation, moving from cave to cave every few days. There also have been isolated reports of South African baboons sleeping in caves.
Ring-tailed lemurs are easily identified by their characteristic, black and white ringed tails, which can be twice as long as their bodies. They weigh roughly 5 pounds with a head-body length of up to 18 inches and are highly social, congregating in groups of up to 30 individuals. Sporting fox-like snouts and slender frames, they are unusual among lemurs, spending a considerable amount of time on the ground feeding on leaves and fruit and socializing, said Sauther.
In “gallery forests” near rivers, ring-tailed lemurs regularly sleep high in the canopies of tall trees. But in “spiny forests,” most of the trees with woody stems are covered in rows of spines, making them uncomfortable as well as dangerous sleeping sites because predators can easily climb them, Sauther said. The new study documents their cave sleeping behavior in the dry spiny forest habitat adjacent to limestone cliffs.
The lemur observations were made at the 104,000-acre Tsimanampesotse National Park and the Tsinjoriake Protected Area in southwestern Madagascar between 2006 and this year. The research team used field observations and motion-detector camera traps to chart the behavior and movements of 11 different troops of ring-tailed lemurs.
One of the early clues to the cave sleeping by the lemurs was their presence on limestone cliffs adjacent to spiny forest trees or on the ground when Sauther’s research team arrived at the study sites early in the morning. “They seemed to come out of nowhere, and it was not from the trees,” she said. “We were baffled. But when we began arriving at the study sites earlier and earlier in the mornings, we observed them climbing out of the limestone caves.”
The primary predator of the lemurs is a cat-like, carnivorous mammal called a fossa native only to Madagascar that is closely related to the mongoose and may weigh up to 20 pounds. Fossil evidence shows a cougar-sized relative of the fossa that only became extinct several thousand years ago likely preyed on lemurs as well, she said.
There is evidence that some early ancestors of humans in South Africa may have used caves to protect themselves from predators, said Sauther. The remains of hominids going back several million years have been found inside or near limestone caves there, and some fossil bones have evidence of damage consistent with the bite of saber-toothed cats.
“We think cave-sleeping is something ring-tailed lemurs have been doing for a long time,” she said. “The behavior may be characteristic of a deep primate heritage that goes back millions of years.”
Co-authors of the new study included Associate Professor Frank Cuozzo of the University of North Dakota, Ibrahim Antho Youssouf Jacky, Lova Ravelohasindrazana and Jean Ravoavy of the University of Toliara in Madagascar, Krista Fish of Colorado College in Colorado Springs, Colo., and Marni LaFleur of the University of Veterinary Medicine in Vienna. Fish and LaFleur are former CU-Boulder students of Sauther.
Sauther co-directs the Beza Mahafalay Lemur Biology Project in southwestern Madagascar with Cuozzo, a former CU-Boulder doctoral student. Centered at the roughly 1,500-acre Beza Mahafalay Special Reserve, the research focuses on how climate- and human-induced change affects lemur biology, behavior and survival.
Sauther and her team were aided by field observations made by students and faculty from the University of Toliara in Madagascar. In addition, undergraduate and graduate students from CU-Boulder regularly travel to Madagascar to conduct research under Sauther, including students from CU’s Undergraduate Research Opportunities Program, which provides hands-on research and fosters student-faculty relationships.
“I never thought I would have a chance as a CU undergraduate to conduct research in an exotic place like Madagascar,” said former UROP student Anthony Massaro, who was part of a team that trapped ring-tailed lemurs, measured their physical characteristics including dentition, and released them back into the wild. “Dr. Sauther and Dr. Cuozzo mentored and guided me through the process of creating and conducting a unique research project.”
Unfortunately, habitat destruction, including deforestation, is increasing in many parts of Madagascar. In southwestern Madagascar, trees are being harvested for cattle forage, construction materials and firewood, and the mining of limestone there — used for the production of cement, fertilizer and other products — is increasing. Ring-tailed lemurs are now listed as an endangered species by the International Union for the Conservation of Nature’s Species Survival Commission.
Sauther has been conducting research on Madagascar for 25 years, beginning as a University of Washington graduate student. Today she has several CU-Boulder doctoral students working with her, including James Millette, who is studying how the tooth wear of lemurs relates to their foraging behaviors.
“Madagascar is a challenging place to conduct research,” Millette said. “Part of our job is to work with local communities, because without the support of these people there would be no lemur conservation. We consider Beza, where we have been working with the community for several decades, to be a real success story.”
