Divers, cadaver dogs search for missing teen

By NBC News staff

Updated at 11:11 a.m. ET -- A dive team from the New Mexico State Police was resuming its search near the dam at Vallecito Reservoir on Monday for Dylan Redwine, a 13-year-old boy who disappeared from his father's home during a court-ordered visitation over Thanksgiving in southwestern Colorado.

According to The Durango Herald, the divers began the search Sunday in an area that cadaver dogs had flagged Saturday while aboard watercraft.

No remains had been found by Monday morning.

Cadaver dogs and patrols were also going out around the 12 miles of shoreline, La Plata County Sheriff?s Office spokesman Dan Bender told NBC News on Monday.

"It's been devastating for the family," Bender said.

Dylan was reported missing on Nov. 19 by his father, Mark, who said he left the house in Vallecito, La Plata County, about 7:30 a.m. and returned a few hours later to find his son gone.?

Dylan was described as 5 feet tall, 105 pounds, blond hair, blue eyes with a fair complexion.?He was last seen wearing a blue and white Duke Blue Devils baseball cap, a black Nike T-shirt, black basketball shorts, black Jordan tennis shoes and a black backpack.

On Saturday, about 200 volunteers and law enforcement officials went door to door in the region and?searched hills near Vallecito Lake, the Denver Post said.

"Every time someone sees a young male child with light hair or with a black backpack we're getting calls," Bender said, adding that there had been no confirmed sightings of Dylan.

The Herald said police are also looking to speak with two boys who were seen by a postal worker on Nov. 19 at the Vallecito Lake Country Market, according to Bender.

The postal worker, who knows Dylan, said one of the boys looked like him, adding that both teens were also wearing black backpacks. As of Monday morning, Bender said police had not heard from the two boys.

According to a news release, the La Plata County Sheriff?s Office is ?working with local representatives of the FBI to share information and resources as they continue to develop leads on where Dylan may be," The Herald reported.

?Scenarios from abduction to runaway are being examined,? the release said. ?Without any new clues, we have to continue to consider any and all possibilities." The FBI has not officially taken over the investigation, Bender told NBC News.

Dylan, his mother and his brother had moved to Colorado Springs this summer, NBC station KUSA of Denver reported.

Vallecito is more than 7,000 feet above sea level in the middle of rugged terrain. The weather in the area in the past few days has been clear and cool, with highs in the 50s and lows below freezing.?

Anyone with information on Dylan's whereabouts is asked to contact La Plata County Sheriff's Office investigators at 970-382-7015 or 970-382-7045.

Vitamin D reported to lower the risk of multiple sclerosis

A new study by Swedish researchers has reported that individuals with high levels of Vitamin D in their blood have a lower risk of developing multiple sclerosis (MS). Researchers affiliated with Ume? University, Ume?, Sweden published their findings on November 20 in the journal Neurology.

The goal of the study was to examine the association between Vitamin D (25-hydroxyvitamin D (25[OH]D)) levels and the risk of MS in blood samples collected prospectively and during pregnancy. (Prospective collection means that the samples were collected before the individuals developed MS.) The investigators evaluated 291,500 blood samples from 164,000 individuals collected since 1975 in the northern half of Sweden. They identified prospectively collected blood samples from 192 MS cases matched two to one with controls matched and samples from pregnant mothers whose offspring had later developed MS (37 women, matched five to one with controls. Vitamin D levels were measured using an ELISA, and the risk of MS was analyzed using matched logistic regression.

The researchers found that Vitamin D levels in prospectively collected blood samples were associated with a decreased risk of MS (odds ratio: 0.39). No decrease in MS risk was found in the offspring exposed to higher Vitamin D levels in utero. The prevalence of Vitamin D levels in the control women decreased gradually from 1976 through 2005.

The researchers concluded that their study supports the presence of an association between high Vitamin D levels during the years preceding disease onset and a decreased risk of MS. In the very limited material with samples drawn in early pregnancy, where month-of-birth effects were controlled for, they found no association between gestational Vitamin D levels and MS risk in the offspring. They noted that decreasing Vitamin D levels in the population may contribute to explain the increasing MS incidence that is suggested from epidemiologic studies.

MS affects woman more than men. The disorder most commonly begins between ages 20 and 40, but can be seen at any age. It is caused by damage to the myelin sheath, the protective covering that surrounds nerve cells. When this nerve covering is damaged, nerve impulses are slowed down or stopped. MS is a progressive disease, meaning the nerve damage (neurodegeneration) gets worse over time. How quickly MS gets worse varies from person to person.

The nerve damage is caused by inflammation. Inflammation occurs when the body's own immune cells attack the nervous system. Repeated episodes of inflammation can occur along any area of the brain and spinal cord. Researchers are not sure what triggers the inflammation. The most common theories point to a virus or genetic defect, or a combination of both. MS is more likely to occur in northern Europe, the northern United States, southern Australia, and New Zealand than in other areas. Geographic studies indicate there may be an environmental factor involved. People with a family history of MS and those who live in a geographical area with a higher incidence rate for MS have a higher risk of the disease.

Symptoms vary, because the location and severity of each attack can be different. Episodes can last for days, weeks, or months. These episodes alternate with periods of reduced or no symptoms (remissions). Fever, hot baths, sun exposure, and stress can trigger or worsen attacks. It is common for the disease to return (relapse). However, the disease may continue to get worse without periods of remission. Because nerves in any part of the brain or spinal cord may be damaged, patients with multiple sclerosis can have symptoms in many parts of the body.

The role of Lure in Greyhound Racing | bettor.com

The role of Lure in Greyhound Racing

Temptation is the key driving force behind every action in this world. Like human beings, animals can also be tempted to do one thing or the other. Temptation has a great say in greyhound racing.

One wonders that how a dog or bitch can run in such a cultured and technical way without any cause. It is wonderful to see such animals behaving on race tracks with decency on their own.

There is an interesting story behind this. To make greyhounds break from traps and run on race track, an artificial prey known as Lure is used. This is a stuffed hare powered by electronic motors and driven by a licensed controller.

Before the start of race, the lure is placed at least 12 yards ahead of the starting trap. As soon as traps open, lure starts running and greyhounds seem to be crazy to catch it.

In order to take on stuffed hare, every runner tries to run fast with his/her mouth watered for pseudo prey. The one who has more potential and urge manages to take lead and resultantly wins contest.

All this looks to be fantastic. There are some people who opine that tempting a hound to run for a fake hare is unfair and injustice. They think it a violation of animal rights.

According to them, the owners of greyhounds engineer all this drama just to make money. The supporters of this notion suggest that a runner applies his/her entire strength to chase a prey, but it proves to be fake in the end.

Though this point of view looks somewhat ridiculous in terms of the sport, but it is valid if perceived neutrally.

But there can be no alternative to lure. If the sport organisers start putting real prey in playfields, the same critics will term it an attempt to kill an animal without reason. Here again come animal rights.

So, in a broad perspective, stuffed hare is a key player in greyhound race. It will not be wrong to say that the sport cannot exist without it. Thus, we must have to enjoy this drama as long as we love the sport.

Deadly La. oil rig fire claims second victim

(Reuters) - One of the men burned last week in an explosion and fire on an oil platform in the Gulf of Mexico died on Friday of his injuries, an official said, bringing the confirmed death toll from the accident to two.

Avelino Tajonera, 49, a welder from the Philippines working on the Black Elk Energy rig, died in a New Orleans hospital on Friday morning, according to a statement from the Philippine Ambassador to the United States. He died shortly after his wife and three children arrived from Manila.

In the wake of the November 16 accident, which killed one other worker and left another missing, U.S. regulators ordered Black Elk to take immediate steps to improve safety at its offshore platforms.

The explosion and fire occurred when workers were welding a pipe on the deck of West Delta Block 32 platform, which sits in 56 feet of water about 17 miles south of Grand Isle, Louisiana.

The accident evoked memories of the deadly 2010 Deepwater Horizon disaster that killed 11 people and triggered the worst oil spill in U.S. history.

A spokeswoman for Black Elk did not immediately return an e-mail from Reuters requesting comment.

Owl feathers inspire quieter change

23 hrs.

Francie Diep , TechNewsDaily

An owl glides by on silent wings. Many holiday travelers probably wish airplanes could do the same.?

"On airplanes, the back edge of the wing is where you get most of the noise," Justin Jaworski, a mathematician at the University of Cambridge in the United Kingdom, told TechNewsDaily. "My work is looking at developing theoretical models to explain trailing-edge noise."

Most recently, he and his colleague Nigel Peake showed, mathematically, that the noise from airplane wings could be reduced tenfold if their designers took a few cues from the feathers that fringe the trailing edge of an owl's wings.?

In their latest research, Jaworski and Peake found that owl wings are especially quiet in part because their trailing-edge feathers are flexible and porous, allowing some air through. Plane wings, of course, are hard and solid. But the pair found that if the edge of a plane's wings were perforated in a particular way, "the theory says you should be able to reduce noise as if there were not an edge there at all," Jaworski said.

Makers of real planes might have a difficult time taking that suggestion. Holes in the wings might reduce a plane's aerodynamics too much for the companies' liking, Jaworski said. Also, flexible trailing edges might flap in the wind, which would also reduce aerodynamics. These are issues that other engineers would work out in later stages of research, Jaworski said. He collaborates with experimental researchers to uncover the engineering trade-offs in his ideas.

In any case, the findings are still in their earliest stages, and it might take two or three years before the ideas for a quieter airplane wing are tested with a small model in a wind tunnel, Jaworski said. After? wind tunnel tests, even more research would go into seeing whether the ideas would be cost-effective in real planes.

Meanwhile, the Cambridge researchers continue to refine their model and study owl wings for further secrets into their quiet flight, Jaworski said.?

On the theory side, the next step is to study other features of owl wings that are not common to noisier flapping birds such as pigeons. "We're really excited about looking at this downy material on top," Jaworski said, referring to a unique, soft covering owl wings have. He said the down covering is difficult to model mathematically, no one has studied it before, and it may be especially important to quiet flight.

Jaworski presented his and Peake's research Nov. 18 in San Diego at a conference hosted by the American Physical Society.
