Field Trip To A Fungi Foray

What happens at the Northeast Mycological Federation Foray? "Mushrooms only," according to attendee Gary Lincoff, an instructor at the New York Botanical Garden and author of The Audubon Society Field Guide to North American Mushrooms. Science Friday stopped by the conference for mushroom talk, mushroom crafts, mushroom eats and a mushroom hunt.

Can Schools Teach Character? 

Listen to Episode 20 of The Afterword:

?Most early-childhood classrooms in the United States,? writes Paul Tough in his new book How Children Succeed, ?are designed to develop in children a set of pre-academic skills, mostly related to deciphering text and manipulating numbers.? Nevertheless, research conducted in the last few years suggests that stuffing this kind of information into a child?s head is not the most important task in those early years. ?What matters, instead, is whether we are able to help her develop a very different set of qualities, a list that includes persistence, self-control, curiosity, conscientiousness, grit, and self-confidence.? How Children Succeed describes the new discoveries and reports on the ways innovative educators are developing techniques to help children develop these traits. The interview lasts about 30 minutes.

Cup qualifying back on track

Was it all a bunch of wasted worry? Was all the teeth gnashing, nervous tummy tumbling and nail biting all so unnecessary after all?

The United States? World Cup qualifying effort, looking unsteady and unbalanced for a few days, is back on solid ground following a 1-0 win over Jamaica in Columbus.

Jurgen Klinsmann?s men were dominant for 65 minutes. In fact, dominant doesn?t tell the story as the United States completed a stunning 91 percent of its first half passes against a Jamaican team that sat in a surprisingly passive and defensive crouch. An otherworldly combo of post- and crossbar-rattlers (three of them in the first 45) and spectacular stuff from Reggae Boyz goaltender Dwayne Miller kept the United States out of goal before the break.

Finally, Herculez Gomez scored unquestionably his biggest goal in a U.S. shirt ? and probably the biggest U.S. goal since Landon Donovan?s late strike against Algeria in the 2010 World Cup. That was the breakthrough ? and the United States is now tied atop the group once again, along with Guatemala and Jamaica.

(MORE: U.S. Man of the Match, Herculez Gomez)

The job isn?t done, but Klinsmann?s kids do have two winnable matches remaining, at Antigua and Barbuda and then back at home against Guatemala. Both games are in October.

More on those later. For now, here are 10 talking points on Tuesday?s massive win.

1.????If U.S. fans feel a bit conflicted about this one, it?s about those final 20 minutes, when the United States lost initiative, backing off following the breakthrough goal. Some was down to Jamaica pressing higher, but the response just wasn?t as convincing as it needed to be.

2. ???Clearly not satisfied with his things from last Friday, Klinsmann made five changes in the lineup, introducing Carlos Bocanegra, Steve Cherundolo, Danny Williams, Graham Zusi and Jose Torres.

3. ???Checks marks on the U.S. side for Geoff Cameron, Cherundolo, Fabian Johnson, Williams, Zusi and Herculez Gomez. Cameron?s work was unimpeachable, and Cherundolo was near-perfect against Luton Shelton, a man much faster that the U.S. right back.

4. ???Torres, a polarizing figure among U.S. fans, did nothing like the night he needed. The U.S. left-sided midfielder wasn?t bad ? but it simply wasn?t enough in a night of U.S. dominance. And isn?t this (?not enough?) always the story with Torres? Klinsmann even said as much last week. For all the U.S. possession, Torres just never manufactured the big moment in the final third. Zusi, playing Torres? equal on the opposite side in the U.S. 4-4-2, managed to make things happen in ways Torres never did. Plus, the ball often slows down when it reaches Torres (and Jermaine Jones, too, for that matter.) Torres was removed after 65 minutes. If he was running out of chances before, where does leave him now?

5. ???Jones? What does Klinsmann see in him? Please submit answers to ProSoccerTalk HQ.

6. ???Even before Gomez?s crucial goal, his free kicks were impressive, creating threatening U.S. chances. His first-half ball into Jones (Jones!) was deadeye perfect; The U.S. midfielder whiffed on the header from top of the six-yard box when he had perfect inside position on his man. (Seriously, Jones is still more liability than asset. The only way the United States was ever going to lose was for Jones to do something stupid and red-card worthy. I said on Twitter in the first half that exact thing ? and put the chances at 27 percent.)

7. ???The Cherundolo-Zusi combo was flat out devastating in the first 45. They looked like they had been playing together since YMCA soccer in grade school. Zusi had the first U.S. chance, banging one off the cross bar in the 6th minute. Meanwhile, Cherundolo was adding so much more push up the right side that just wasn?t there on Friday.

8. ???Williams was the primary holding man in a 4-4-2 and had his best night in the U.S. shirt by a long way. That shouldn?t be so surprising since that?s his position in Germany; Klinsmann, with a wealth of central midfielders has usually played Williams out wide. I think we just saw that change. If so, one of the usual central midfielders is odd man out, either Jones, Maurice Edu or Kyle Beckerman.

9. ???Not so sharp? Clint Dempsey did what he could, but his touch and timing are clearly not Dempsey-esque. You really have to wonder about the choice to play him all 90 minutes Tuesday, especially after he went all 90 tough minutes on Friday. That man was wiped out by the 60th minute in Columbus by the look of it.

9a. ???Bocanegra was similarly stale. Not bad, just not World Cup qualifier sharp, with a bad choice here and there while bringing the ball out of the back. And he got dragged out of position once, stranding Cameron behind him as Jamaica buzzed in dangerously.

10. ???In the last 20 minutes the United States looked nervous as schoolboys at the junior high dance. Credit for the three points, which was always the bottom line. Still, you?d like to see the American manage things better late, more convincingly nursing home the 1-goal margins. Maybe that?s a nitpick, but it?s not much of one.

Body heat, fermentation drive new drug-delivery 'micropump'

ScienceDaily (Sep. 11, 2012) ? Researchers have created a new type of miniature pump activated by body heat that could be used in drug-delivery patches powered by fermentation.

The micropump contains Baker's yeast and sugar in a small chamber. When water is added and the patch is placed on the skin, the body heat and the added water causes the yeast and sugar to ferment, generating a small amount of carbon dioxide gas. The gas pushes against a membrane and has been shown to continually pump for several hours, said Babak Ziaie, a Purdue University professor of electrical and computer engineering and biomedical engineering.

Such miniature pumps could make possible drug-delivery patches that use arrays of "microneedles" to deliver a wider range of medications than now possible with conventional patches. Unlike many other micropumps under development or in commercial use, the new technology requires no batteries, said Ziaie, who is working with doctoral student Manuel Ochoa.

"This just needs yeast, sugar, water and your own body heat," Ziaie said.

The robustness of yeast allows for long shelf life, and the design is ideal for mass production, Ochoa said.

"It would be easy to fabricate because it's just a few layers of polymers sandwiched together and bonded," he said.

Findings were detailed in a research paper published online in August in the journal Lab on a Chip. The paper was written by Ochoa and Ziaie, and the research is based at Purdue's Birck Nanotechnology Center in the university's Discovery Park.

The "the microorganism-powered thermopneumatic pump" is made out of layers of a rubberlike polymer, called polydimethylsiloxane, which is used commercially for diaphragms in pumps. The prototype is 1.5 centimeters long.

Current "transdermal" patches are limited to delivering drugs that, like nicotine, are made of small hydrophobic molecules that can be absorbed through the skin, Ziaie said.

"Many drugs, including those for treating cancer and autoimmune disorders cannot be delivered with patches because they are large molecules that won't go through the skin," he said. "Although transdermal drug delivery via microneedle arrays has long been identified as a viable and promising method for delivering large hydrophilic molecules across the skin, a suitable pump has been hard to develop."

Patches that used arrays of tiny microneedles could deliver a multitude of drugs, and the needles do not cause pain because they barely penetrate the skin, Ziaie said. The patches require a pump to push the drugs through the narrow needles, which have a diameter of about 20 microns, or roughly one-fourth as wide as a human hair.

Most pumps proposed for drug-delivery applications rely on an on-board power source, which is bulky, costly and requires complex power-management circuits to conserve battery life.

"Our approach is much more simple," Ziaie said. "It could be a disposable transdermal pump. You just inject water into the patch and place it on your skin. After it's used up, you would throw it away."

Researchers have filed an application for a provisional patent on the device.

Top five fights to look forward to in September

We're in the middle of an unexpected slow period of MMA. With the cancellation of UFC 151 and UFC 152 still a week and a half away, it doesn't feel like fight fans have much to look forward to. With a sport as constant as MMA, our attention spans are short. But hold on, Cagereaders. We still have plenty to look forward to in September. For example, in no particular order:

Joe Benavidez vs. Demetrious Johnson for the first UFC flyweight title at UFC 152, Sept. 22: Of course, the lion's share of publicity will go to the Jon Jones/Vitor Belfort at title fight, but expect the 125-lbers to steal the spotlight. Both Benavidez and Johnson bring exciting fights with them into every bout, and now they'll get to show off their skills for five rounds.

Dan Hardy vs. Amir Sadollah at UFC on Fuel 5, Sept. 29: Both Hardy and Sadollah are in need of a win and capable of finishing fights. Plus, I can't wait to hear how the crowd in Nottingham will erupt when Brit favorite Dan Hardy walks out.

Nordine Taleb vs. Marius Zaromskis at Bellator 74, Sept. 28: I always mark my calender when Zaromskis is fighting. Of his 18 wins, 13 are by knockout, but he is susceptible to being knocked out, too. Either way, this opening round bout of the Bellator welterweight tournament is likely to end in a highlight.

David Armas vs. Darrion Caldwell at Legacy Fighting, Sept. 14: This fight is highly anticipated by college wrestling fans. Caldwell won a national championship for North Carolina State over the highly touted Brent Metcalf from Iowa. Fans either love him or hate him, and will be tuning in with the hopes of Caldwell owning his MMA debut or him getting knocked out by Armas.

Jorge Santiago vs. Quinn Mulhern at Strikeforce, Sept. 29: Santiago had a tough go in the UFC, losing back-to-back fights before winning two fights in the Titan Fighting Championships. He will get another chance to prove himself at Strikeforce against Mulhern, who is riding a three-fight win streak.

Which fights are you looking forward to? Speak up in the comments, on Facebook or Twitter.

Is Microsoft making a gaming holodeck for your home?

6 hrs.

According to a patent filed by Microsoft, it looks like the video?games of the future could take over our entire living rooms ? holodeck style.

Microsoft has?filed a patent with the U.S. Patent and Trademark Office for "an interactive computing system configured to provide an immersive display experience." That immersive display experience means that the games you play?would be projected on all?four?walls of your living room.?

How would this work? For a sneak peek, see?the images above and below, which?Microsoft submitted to the patent office.

Microsoft summarizes what it's?working on like this:?"An immersive display environment is provided to a human user by projecting a peripheral image onto environmental surfaces around the user. The peripheral images serve as an extension to a primary image displayed on a primary display."

What that means is, while the player is focused on the primary display ? both the TV and the wall in front ??"they may be aware of an approaching video game enemy" from the?images displayed on the?surfaces around them, reads the patent. Meanwhile,?"the user may turn around and observe an enemy sneaking up from behind."

The lengthy?patent submission says the system would include: an?"interactive computing system" (i.e. a game console), an?"environmental display device" (for projecting the images on the walls around you), a "depth camera" and a "user tracking device" ? the?latter of which refers to the Kinect-looking gadget pictured in the top image.

Meanwhile, according to the patent submission, 3-D headgear may (or may not) also be used with the system.

How far off in the future we might see this new gaming experience isn't clear; nor is it clear whether this is a project Microsoft is working on in conjunction with?its next home game machine. But the patent filing has certianly?added fuel to the rumors already flying around that yet-to-be-revealed machine ? which has been dubbed the Xbox 720.?

One thing is for sure, Microsoft is very?interested in finding more immersive ways for you to experience your video?games. Earlier this year, documents were leaked that purported to show off Microsoft's new game?machine as well as the?next generation of Kinect ??a system that?would make use of?augmented reality glasses.

And Microsoft's not alone. The Oculus Rift virtual reality goggles?(see video below)?have been gaining a lot of buzz and a lot of support in the gaming community. Meanwhile,?these students are working on a holodeck project of their own.

After all, who doesn't want to live the holodeck dream??
