He worked on a more consistent step-back, which he now uses when he drives the lane or is in isolation, rising high in the air with a ramrod-straight form that gives him a clean look at the rim. Providence coach Ed Cooley is also using Dunn off the ball, letting teammate Kyron Cartwright run point while Dunn comes off several screens. That allows Dunn to either feed Ben Bentil, a hulking sophomore forward — or catch-and-shoot a pass from a teammate. Dunn spent the offseason working with former Providence guard God Shammgod, who has become a quasi mentor-trainer to Dunn. They had several goals in mind: First, Dunn needed to upgrade his jump shot, which was wildly inconsistent from just about everywhere on the court. Second, he needed to tighten his handle to limit turnovers. And third, he had to develop several countermoves, should savvy defenders who had studied game film fail to bite on Dunn’s initial move.Dunn’s jump shot as a sophomore was streaky — a reel full of bad, caroming rocks that either just hit the backboard or fell wildly off the back iron. Since his long arms make it nearly impossible for a defender to block his shot, it was a priority that he improve this component of his game to maximize his advantages. He also gets great separation thanks to a quick first step and a backpack full of crosses, between-the-legs moves and feints. Providence’s Kris Dunn won’t win player of the year honors (that’ll almost certainly go to Oklahoma’s Buddy Hield), nor will he be the top choice in the upcoming NBA draft (LSU’s Ben Simmons should be No. 1), but he’s worth watching for the way his unique set of skills turns into thrilling plays — for better and worse. The 6-foot-4 junior is the most exciting player in the game, precisely because he isn’t as cookie cutter as other top prospects.Dunn did two things particularly well last season, as I covered in-depth last year in an article for Deadspin1At the time, I wish he had used the momentum of his standout sophomore season to declare for the NBA draft, where he would have likely been a first-round pick.: He had a preternatural sense of where his fellow Friars were at all times on the court, and he used his length and athleticism to finish plays that, at first glance, appeared ill-advised. There were countless possessions where Dunn would dribble off a screen 25 feet from the basket and whip a one-handed underhand pass to a cutter for the dunk; or, with enough time to run a set play in overtime, he would instead push the ball frenetically up the court to hit a teammate for an and-one before the defense set.College point guards don’t typically make those decisions. More often they make the careful pass — the assist the coach has hard-coded into the play call — or the pass they’ve practiced for years and feel comfortable throwing. Dunn, though, has such innate skill and creativity that he attempts passes that should have a high rate of failure, but often succeed because the defense isn’t expecting them. That style allowed Dunn to lead the nation in assist percentage (at a staggering 50.0 percent last season, and 44.2 during this campaign2To put this in context, just 23 other high-major point guards had assist rates above 30 percent, and just two — Denzel Valentine of Michigan State and Oklahoma State’s Jawun Evans — topped 40 percent.). Thrilling as all that was, it often led to some alarmingly bad turnovers — about 20 percent of his possessions — even when you take into account his high usage rate.But this season, the consensus is that Dunn is the nation’s top point guard. To become it, Dunn had to make a few tweaks to his game. According to Synergy Sports Technology, Dunn’s spot-up numbers are still below average, but he now scores one point per catch-and-shoot possession — that’s pretty good, and a vast improvement over the .76 points he scored a year ago. And his jumper should only get better given the fundamental improvements he made in the offseason. Dunn is connecting on 37 percent of his threes while taking them at a far higher rate than last season — 25.9 percent of his field goal attempts, up from 19.7 last season. He now shoots with the perfect follow through — his arms extend and his hands rest like they’re in a cookie jar. The shots that were ugly bricks are beginning to show just a little more touch, like the game winner he hit against Creighton, which hit the flat section of the bucket that connects to the backboard, died on the rim, and finally rolled softly in.Some have criticized Dunn, and his NBA potential, because of his turnovers. Though the guard assists on 45 percent of Providence’s shots, which is second in Division I, he also gives the ball away on 85 of his 425 possessions (through Providence’s loss to Marquette this week). Since Dunn’s dimes typically account for about 2.4 points in the halfcourt and transition, the Friars have missed out on more than 200 points this season when Dunn loses control.On other teams, those miscues might find a guard strapped to the bench. But for Dunn the giveaways don’t matter. A 25-foot pass through Xavier’s 1-3-1 zone defense during a game in late February is the kind of play Cooley wants, regardless of the risk. Midway through the first half, Dunn saw a brief opening between Larry Austin and Kaiser Gates, and threaded a pass (from Providence’s half-court logo) to Bentil, who certainly wasn’t calling for the ball but was able to convert an and-one. Similarly, Cooley needs his junior guard to consistently draw the defense’s attention so his Friar ‘mates can benefit from that extra second of breathing room. This happened in a Villanova victory when Dunn slipped a backdoor pass to Junior Lomomba: He wasn’t doubled, but Dunn reacted to all five Villanova players tracking his moves as he came off a Bentil pick. Again, Lomomba wasn’t exactly expecting the ball, but he made the lay-up. Sure, Dunn will take some shots — like a one-on-three fast break that has become a bit of a staple of his game this season — that might cause some to cringe. But Cooley is willing to incur the cost of a few bad shots if it means his squad can operate with offensive impunity.Dunn’s impact on the game, negative and positive, is what makes him so fascinating to watch. Buddy Hield, Ben Simmons, and Maryland’s Melo Trimble are equally as talented, impressive, and fun to watch, but none inspire quite the same combination of mouth-agape incredulity and absolute production as Dunn. So when he puts the ball behind his back, then crosses over Michigan State’s Tum Tum Nairn, only to follow with a spin move to the rack and then misses the layup, don’t think of it as a wasted possession. Instead, imagine it as a thrilling experiment in risk and reward, the type of audacious and improvisational brilliance that the college game doesn’t produce anymore.

The finding that eumelanin survives for millions of years opens the opportunity for pathologists to analyze the eumelanin from decades-old tissue samples of cancer patients in order to better understand the different characteristics of a melanoma that spreads versus a melanoma that does not spread. Credit: Mary Jane Simpson, et al. ©2013 American Chemical Society The researchers, Mary Jane Simpson, et al., led by Professor Warren S. Warren at Duke University in Durham, North Carolina, have published their paper on their analysis of Jurassic-aged eumelanin in a recent issue of The Journal of Physical Chemistry Letters.”Melanoma is a particularly bad cancer if it metastasizes,” Warren told Phys.org. “Unfortunately, the ‘gold standard’ of conventional diagnostic techniques (essentially, excision followed by pathology) does not do a very good job of predicting which diagnosed cancers are likely to spread. So, how do you fix a bad gold standard for a bad disease?”The best answer is retrospective studies—looking at decades-old specimens from patients, where you know the outcome—and trying to find systematic differences. That is impossible with most pathology methods because the tissue degrades. Our results show that it is possible with melanin-based diagnostics, since the melanin easily survives that long.”The researchers explain that human skin has two types of melanin, eumelanin and pheomelanin. The distribution of these two types assists in the diagnosis of melanoma skin cancer. One way to identify the types of melanin and their distribution in a given sample is to use a molecular imaging technique called pump-probe microscopy. Basically, an ultrafast laser pulse is first used to “pump,” or optically excite, the molecules. Then after a short time delay, one or more follow-up pulses are emitted to “probe” the molecules. By measuring how the probe pulses are absorbed or reflected by the molecules, researchers can obtain a pump-probe signature that reveals information on the molecules’ excitation decay process. Since eumelanin and pheomelanin have different pump-probe signatures, this technique enables scientists to distinguish between them.

(Despite its name, cuttlefish are mollusks, not fish.) Although the Jurassic-era cephalopod is 162 million years older than its modern counterpart, the eumelanin pump-probe signatures of the two animals are essentially identical. This finding shows that eumelanin is extremely stable, and could potentially permit researchers to image archived tissue samples from deceased cancer patients and uncover more information than could be obtained through more traditional methods that analyze other, less stable chemicals. Squid ink from Jurassic period identical to modern squid ink, study shows Journal information: Journal of Physical Chemistry Letters The researchers pointed out that they did find some variations in the eumelanin signatures from the two mollusks. However, they could trace these variations to the larger iron content in the ancient eumelanin compared with the modern sample. Eumelanin from the common cuttlefish is normally bound to a variety of transition metals such as iron, copper, and manganese, but washing the eumelanin with the solid acid EDTA removes the majority of the bound metals. When the researchers washed the ancient eumelanin with EDTA, its signature closely matched that of the modern, mostly iron-free eumelanin. Because iron affects the pump-probe signature of eumelanin, the microscopy technique could also potentially enable researchers to approximate the iron content of a sample. For example, pigmented human tissue often exhibits a wide range of pump-probe signatures, and some of the variation may be due to metal ion binding by the melanin. In the future, pathologists may use this knowledge to their advantage when investigating the molecular composition of eumelanin samples. Explore further © 2013 Phys.org. All rights reserved.

Melanin is the biological pigment that determines an animal’s color, and is currently not very well understood. In the new study, scientists have found that a type of melanin called eumelanin from a Jurassic-era mollusk produces a signature when optically excited that is nearly identical to that of the optically excited eumelanin from its modern counterpart, Sepia officinalis, or the common cuttlefish. Because melanin survives so long, an analysis of the melanin from old cancerous tissue samples could give researchers a useful tool for predicting the spread of melanoma skin cancer in humans.
Free Workshop | August 28: Get Better Engagement and Build Trust With Customers Now Enroll Now for Free The Jetsons, that candy-colored cartoon about a family living in the future, was actually a bit of a time traveler.It premiered in 1962 on ABC and was the network’s first show to ever be broadcast in color. But this new-age way of viewing a television show didn’t help The Jetsons, as it only lasted 24 episodes before being cancelled thanks to poor ratings. The production company Hanna-Barbera (the minds behind The Flintstones and Scooby-Doo) gave it another shot and revived it in the ’80s with new episodes that ran in syndication from 1985 to 1987. The cartoon wasn’t around for all that long compared to some of its contemporaries, but its impact is an enduring one. True, there are some aspects of it that are a bit dated — you don’t see a lot of parents naming their sons Elroy nowadays — but it was remarkably prescient about where technology was headed.From interactive newspapers to video chatting, here are some of the inventions from The Jetsons that are a part of our world today.1. Flying cars.Image credit: Jetsons / AeromobilGeorge Jetson’s flying car converted into a portable briefcase, which is arguably pretty cool. While the car improvements haven’t trended in that direction just yet, the team at Slovakian startup AeroMobil is hard at work on a car that can turn into an airplane and vice versa.
