The highly rated defender is Clemson’s Nathan Sturgis, who according to some reports was the second-best defender behind only UCLA’s Marvell Wynne in last weekend’s player combine at Home Depot Center. Cal State Northridge forward Willie Sims, who went to New England at No. 23, was among the possibilities for the Galaxy with the last pick (12th overall) in the first round, but the nod went to Sturgis. He stands 5-foot-10 and weighs only 150 pounds, but Galaxy coach Steve Sampson and president and general manager Doug Hamilton said the slender physique is misleading. Galaxy officials were more than pleasantly surprised at how Friday’s Major League Soccer SuperDraft panned out in Philadelphia. They not only selected one of the top defenders in last week’s player combine, but they also chose a player they felt was the best left-sided midfielder in the talent pool.

In the case of him and Burch, we were very, very pleased they were around.” Sampson was referring to midfielder Marc Burch, their No. 2 pick (24th overall), who scored the game-winning goal for Maryland in last season’s NCAA Division I soccer final against New Mexico. Hamilton said the Galaxy rated the 6-2, 190-pounder, who was not invited to participate in the combine, as the best left-sided player in the draft. “Period,” Hamilton said. “We were surprised he was there. That was a pretty good surprise.” “We felt he was one of the best players in the Final Four and the best player for Maryland in the final,” Sampson said. “We believe he’s the biggest surprise of the draft. The fact he wasn’t at the combine, I think we were able to hide him a little bit.” The Galaxy had two third-round picks and spent them on Ohio State defender Kyle Veris – a 6-3, 170-pound converted striker – and Bradley goalkeeper Chris Dunsheath, who likely will stay in school. Their fourth-round choice – the 48th and final pick in Friday’s draft – was used on North Carolina State forward Aaron King, who scored 44 goals in 75 career games with the Wolfpack. He was a first-team, All-ACC choice in 2003-2005. “He has incredible speed and was one of the best athletes in the combine and draft,” Sampson said. “I believe we found a great athlete with our last pick.” Hamilton said it was a good day all around. “Overall, we feel good about the guys we were able to acquire,” he said. “We were surprised some of them were available when it came time for us to be picking. We’re hoping to find guys like Joe (Ngwenya), Ugo (Ihemelu) and Troy (Roberts) to come in pretty early and contribute and get minutes.” [email protected] (626) 962-8811, Ext. 2272 160Want local news?Sign up for the Localist and stay informed Something went wrong.

When a beam of light hits your eye, a chain of events is set off that is really quite amazing. Kendall J. Blumer (Washington University School of Medicine) describes a little of it in the Jan. 1 issue of Nature.1 You don’t have to understand the following description; just be glad you don’t have to operate your retina in manual mode:Light streaming into the eye is detected by specialized neurons (photoreceptors) in the retina. In response to light, a coordinated series of molecular events � the so-called phototransduction cascade � is triggered in these cells (Fig. 1). Photons excite pigment-containing proteins called rhodopsins, which then switch on the protein transducin by loading it with the small molecule guanosine triphosphate (GTP). When bound to GTP, transducin turns on a phosphodiesterase, an enzyme that breaks down cyclic guanosine monophosphate (cGMP � another small molecule). High concentrations of cGMP open specialized ion channels in the outer cell membrane. Thus, by reducing the concentration of cGMP, light changes the flow of ions across the membrane of photoreceptive neurons, producing an electrical signal that is necessary for communicating with the brain. (Emphasis added in quotes.)Now that’s just to turn the signal on. When the light stops, it needs to be turned off quickly. Normally, it would take too long for this process to reverse, but the retina has a standard procedure that takes care of it:But this presents a problem. Photoreceptor cells can turn off in less than a second in response to a brief flash of light. In contrast, the hydrolysis of GTP by transducin requires tens of seconds to complete, making it difficult to understand how such a mechanism could account for the rapid turn-off of photoreceptor cells. To get around this problem, photoreceptor cells possess a protein called regulator of G-protein signalling 9 (RGS9) that accelerates transducin’s ability to hydrolyse GTP.Blumer describes what happens when a person has a defect in this accelerator protein. It can take tens of seconds to adjust to a bright room when walking out of a theater. It can take tens of seconds to see when driving into a dark tunnel. And perhaps the worst of all (for Rose Bowl fans): “Moreover, people with this problem also suffer from difficulties in seeing certain moving objects (such as balls thrown during a sporting event).” Having one such accelerator protein would be amazing enough, but now – the rest of the story: “RGS9 is one of nearly 30 such RGS proteins, which regulate signalling by hundreds of receptors coupled to transducin-like G proteins in cell networks of the nervous, cardiovascular, sensory and immune systems.”Kendall J. Blumer, “Vision: the need for speed,” Nature 427, 20 – 21 (01 January 2004); doi:10.1038/427020a.We need to know things like this to avoid taking our bodies for granted. This one deserves a little pondering. Do some simple experiments; see how quickly your eye adjusts to different light levels, and think about all those little protein machines knowing just what to do on cue. Poor Charlie. The eye as he knew it was enough to give him cold shudders. In 1859, biochemistry was not even a science yet. Charlie must be approaching absolute zero by now. A book preceding The Origin of Species by about 2900 years, by a wiser man (Solomon), makes a lot more sense after reading the above description: “The hearing ear and the seeing eye, The LORD has made them both” (Proverbs 20:12).(Visited 13 times, 1 visits today)FacebookTwitterPinterestSave分享0
Share Facebook Twitter Google + LinkedIn Pinterest By Dan Armitage, host of Buckeye Sportsman, Ohio’s longest running outdoor radio showWith the state fair opening Wednesday, July 24, the Ohio Department of Natural Resources (ODNR) begins welcoming folks to the Natural Resources Park with free interactive exhibits and displays. Located in the southeast corner of the state fairgrounds, the park will be open from 11-7 daily through Sunday, August 4.Two wildlife buildings that made their debut at the 2017 Ohio State Fair include the Wild Ohio Shooting Range, which houses archery and air gun ranges for all ages. The second is the Fish Ohio Building, a redesigned fish house where Division of Wildlife staff offer fish filleting and cooking demonstrations. The building also houses refrigerated storage to temporarily hold fish caught in the youth fishing area until kids are ready to pick them up and take them home.Another popular attraction is the Scenic Rivers touch pool, which contains many of Ohio’s native macro invertebrate species, plus a few crayfish and small stream fish. The touch pool allows visitors to experience the magic of dipping a hand into a stream to find live critters, and it shows how the Scenic Rivers program monitors these creatures to help gauge stream health.Returning exhibits include the popular kayak pond, which is a 7,000-square-foot pond, which gives guests an opportunity to safely learn how to kayak. Additionally, located near the kayak pond, the personal watercraft simulator will be available, allowing visitors to experience “riding” a jet ski.A new animatronic Smokey Bear was installed a few years ago, replacing the original 55-year-old Smokey that annually scared the bejesus out of my now-19 year old son by greeting him by name. The new display has moving arms, head and mouth, which allows him to continue sharing his mission by teaching fairgoers how they can prevent wildfires. Smokey Bear still greets each child who visits from 11 a.m. to 6 p.m. daily. A 71-foot-tall fire tower, originally built by the Civilian Conservation Corps in 1934 in Pike County, is also located directly behind Smokey to reinforce the icon’s fire prevention message.The recently expanded ODNR Amphitheater offers daily performances throughout the fair, from lumberjack competitions, animal demonstrations with animals from the Columbus Zoo and Aquarium, a retriever dog show and music and clogging performances. Other educational opportunities are available, including the Butterfly House, Ruthven’s Aviary, and a walk-through tall grass prairie exhibit.And of course, the youth fishing pond; perhaps the most popular destination in the Park — at least for kids 13 years and younger and the adults who enjoy watching them fish for the 2,000 hybrid bluegills stocked in the pond.I rarely miss the state fair and never miss spending a good deal of time exploring the Natural Resources Park there.
October 21, 2016On Wednesday evening Ian McClerin and Trinity Divelbiss organized a wonderful pumpkin carving event. Leah Ann Walker took all of the photos, thank you!There was scary music to get into the Halloween Spirit, there was lighting in the Colly Garden to resemble a pumpkin patch, spooky blue lighting in the Vaults.This was a first time pumpkin carving event for some of our International crew.[photo Flavio Borrelli and Ian McClerin]Sean-Paul VonAncken There were buckets to save the pumpkin seeds to roast them for later treats. A wonderful time was had by all! Ivan SeveriZebulon HornbergerErin McLoughlin Juan Diego Montanze
