How to Stay Safe at the Amusement Park

May to September is prime time for fun at the amusement park. From frightening news reports to personal YouTube videos, there is no shortage of amusement-ride scares. But a new study has found that it's not always the biggest and fastest rides we should fear.

Smaller ones, which parents might not consider as dangerous, contribute to injuries of more than 4,000 U.S. children each year.

Destiny Malone was just eight when she broke her arm by reaching out while riding a seemingly innocuous kiddie roller coaster.

"When I took her to the emergency room, that's when I found out it was broken," her mother, Crystal Malone, said.

The study, in the journal Clinical Pediatrics, tracked injuries on all kinds of rides: 4,400 per year -- up to 20 a day. When researchers looked at emergency records on which the type of ride was recorded, roller coasters accounted for 10.1 percent, bumper cars 3.9 percent.

But carousels accounted for 20.9 percent -- which might explain why one third of kids injured were five or younger.

The most common kind of accident was falling.

Industry advocates told ABC News that safety is their top priority, and pointed out that injuries among the nearly 300 million riders at their parks are rare. Less than two percent of these injuries required a trip to the hospital, they added.

The best advice may be to take seriously the warnings and instructions on the rides. And if your child may not be able to heed them for any reason, get ice cream instead.

A Clever Plastic Brace Turns Long-Stemmed Flowers Into Their Own Vase

Florists around the country, pay attention. If you're looking for a value-added reason for people to buy a dozen roses from your shop, then find a way to get this brilliant Crown Vase put into production and include one with every bouquet.

Designed by Lambert Rainville, a student at the Royal College of Art, the Crown Vase works as a support allowing flowers to stand via their own stems, like a simple shelter crafted by an experienced outdoors person. A shallow dish or bowl full of water is still needed to keep the flowers alive for more than a day, but when they eventually die everything can be composted and recycled, making cleanup an eco-friendly affair.

Google Glass exploration demonstrates a hidden browser and more (video)

While it's known that Google Glass has in-testing features just waiting to be exposed, we haven't seen many attempts to reveal them all. Zhuowei Zhang has stepped in with a complete list of what's under the hood, and it turns out that some of those features work... more or less. After modding the latest Glass firmware, Android Police can confirm that there is a functional Chrome browser lurking inside; Google just hasn't woven it into the user experience. Other Labs features produce similarly mixed results. OK Glass Everywhere lets users easily start a voice command chain from anywhere in the interface, but a video stabilization mode clearly isn't ready for prime time. Although you'll want to visit the source links for the full rundown, it's evident from just a cursory glimpse that Glass has plenty of room to grow.

A vacation to the moon: Worth the splurge?

NASA isn't planning a return trip to the moon, but private companies are speculating on the Moon's tourism and colonization possibilities. How much would you pay for a trip?

By Mike Wall,?SPACE.com / May 23, 2013

The moon rises behind clouds lit from the setting sun on Thursday, May 23, 2013, in Gainesville, Fla. Now that NASA's priorities have shifted away from the moon, private aerospace companies are speculating about the next great leap in human exploration.

Human exploration of deep space is looking more and more like a tag-team affair, with NASA jetting off to asteroids and Mars while the private sector sets up shop on the moon.

While NASA has no plans to return humans to the lunar surface anytime soon, private industry is eyeing? Earth's nearest neighbor intently, said?Bigelow Aerospace?founder and president Robert Bigelow.

"The brass ring for us is having a lunar base ? as a company and in conjunction with other companies, and even other, possibly, foreign entities as well," Bigelow said during a teleconference with reporters today (May 23). "That is an appetite and a desire that we've had for a long, long time."

Two months ago, NASA tapped Bigelow Aerospace to sound out the private sector's interest and intent in going beyond low-Earth orbit, in an attempt to help map out possible public-private partnerships in deep space.

The Space Act agreement set out a two-phase study approach. Bigelow delivered a draft report of the Phase 1 findings today to NASA human exploration chief Bill Gerstenmaier, who also participated in the teleconference.

Bigelow Aerospace makes expandable habitat modules designed to house astronauts in space or on the surface of?the moon?and other bodies. The company has long been an advocate of setting up manned lunar bases, and Bigelow said other firms see the appeal of commercial lunar operations as well.

Golden Spike, for example, aims to begin launching two-person missions to the lunar surface and back by 2020. And several different firms, such as Shackleton Energy Company and Moon Express, plan to mine the moon's resources.

NASA had been planning on sending astronauts back to the moon until 2010, when President Barack Obama directed the space agency to work instead toward getting to a near-Earth asteroid by 2025, then on to the vicinity of?Mars?by the mid-2030s.

Gerstenmaier said NASA welcomes private industry's interest in the moon, viewing it as a complement to the agency's plans in deeper space.

"NASA and the government, we focus on maybe deep space, we focus on asteroids. The private sector picks up the lunar activity, and then we'll combine and share with them to see what makes sense," Gerstenmaier said.

"Transportation to the same region is common between us," he added. "Other aspects ? life-support ? are common between us. We can do lots of co-development between these that actually share what the private sector needs and what the government needs."

Bigelow said he talked to around 20 private companies during the course of the study, including major players such as SpaceX, Boeing and Sierra Nevada Corp.

"You would recognize most of the names," he said.

Gerstenmaier said NASA would release the Phase 1 report to the public after the agency receives the final draft. The Phase 2 portion of the study, meanwhile, is slated to last four months.

Renan Barao, John Cholish and Cain Velasquez: See where they fell on Cagewriter?s Hot or Not list

As another week of MMA comes to a close, let's take a look at what was hot and what was not so hot.

Hot -- Bryan Pedersen: Many legislators have talked about the economic benefits of MMA when the sport is legalized. Few have gone the extra mile to find out what it feels like to be in a cage to fight. Pedersen will do that in Cheyenne, Wyo., this weekend. No matter the result, it's admirable that he has even gone the distance to train and join the first fights to take place in Wyoming's capitol.

Not -- Renan Barao: The interim bantamweight men's champ was injured and had to pull out of his main event bout with Eddie Wineland at UFC 161. Dan Henderson and Rashad Evans' fight is now the main event, and Roy Nelson vs. Stipe Miocic was added.

Hot -- John Cholish: After losing to Gleison Tibau at UFC on FX 8, Cholish decided to hang up his fighting gloves. Before he left, he decided to give his fight purse to Oklahoma tornado survivors.

To update I just received my fight purse payment of $2,014 from Zuffa. I will be donating 100% of it to charity-Oklahoma Tornado Victims

? John Cholish (@JohnCholish) May 23, 2013

Kudos to Cholish.

Not -- Brett Atchley: The manager who specializes in female fighters has been accused of bad behavior by several fighters separately. His alleged improprieties include accosting fighters, telling them he would "blackball them" from Invicta though president Shannon Knapp has denied anyone has the power to do this, and sharing the confidential details of a client's contract. His response?

"It's really easy for women to play the victim, especially when they make their mind up that they're going to do it. Because everyone will believe them," Atchley said to MMA Junkie.

Stereotyping women is not a smart thing to do, particularly by someone who makes his living off of them.

Still taking temperature -- Cain Velasquez: He lost the UFC heavyweight championship belt once, and managed to get it back. Will he defend it on Saturday night against Antonio Silva at UFC 160?

Thanks for reading Cagewriter this week. Check us out on Twitter and Facebook for bonus UFC 160 coverage.

Hubble reveals the Ring Nebula?s true shape

May 23, 2013 ? The Ring Nebula's distinctive shape makes it a popular illustration for astronomy books. But new observations by NASA's Hubble Space Telescope of the glowing gas shroud around an old, dying, sun-like star reveal a new twist.

"The nebula is not like a bagel, but rather, it's like a jelly doughnut, because it's filled with material in the middle," said C. Robert O'Dell of Vanderbilt University in Nashville, Tenn. He leads a research team that used Hubble and several ground-based telescopes to obtain the best view yet of the iconic nebula. The images show a more complex structure than astronomers once thought and have allowed them to construct the most precise 3-D model of the nebula.

"With Hubble's detail, we see a completely different shape than what's been thought about historically for this classic nebula," O'Dell said. "The new Hubble observations show the nebula in much clearer detail, and we see things are not as simple as we previously thought."

The Ring Nebula is about 2,000 light-years from Earth and measures roughly 1 light-year across. Located in the constellation Lyra, the nebula is a popular target for amateur astronomers.

Previous observations by several telescopes had detected the gaseous material in the ring's central region. But the new view by Hubble's sharp-eyed Wide Field Camera 3 shows the nebula's structure in more detail. O'Dell's team suggests the ring wraps around a blue, football-shaped structure. Each end of the structure protrudes out of opposite sides of the ring.

The nebula is tilted toward Earth so that astronomers see the ring face-on. In the Hubble image, the blue structure is the glow of helium. Radiation from the white dwarf star, the white dot in the center of the ring, is exciting the helium to glow. The white dwarf is the stellar remnant of a sun-like star that has exhausted its hydrogen fuel and has shed its outer layers of gas to gravitationally collapse to a compact object.

O'Dell's team was surprised at the detailed Hubble views of the dark, irregular knots of dense gas embedded along the inner rim of the ring, which look like spokes in a bicycle wheel. These gaseous tentacles formed when expanding hot gas pushed into cool gas ejected previously by the doomed star. The knots are more resistant to erosion by the wave of ultraviolet light unleashed by the star. The Hubble images have allowed the team to match up the knots with the spikes of light around the bright, main ring, which are a shadow effect. Astronomers have found similar knots in other planetary nebulae.

All of this gas was expelled by the central star about 4,000 years ago. The original star was several times more massive than our sun. After billions of years converting hydrogen to helium in its core, the star began to run out of fuel. It then ballooned in size, becoming a red giant. During this phase, the star shed its outer gaseous layers into space and began to collapse as fusion reactions began to die out. A gusher of ultraviolet light from the dying star energized the gas, making it glow.

The outer rings were formed when faster-moving gas slammed into slower-moving material. The nebula is expanding at more than 43,000 miles an hour, but the center is moving faster than the expansion of the main ring. O'Dell's team measured the nebula's expansion by comparing the new Hubble observations with Hubble studies made in 1998.

The Ring Nebula will continue to expand for another 10,000 years, a short phase in the lifetime of the star. The nebula will become fainter and fainter until it merges with the interstellar medium.

Studying the Ring Nebula's fate will provide insight into the sun's demise in another 6 billion years. The sun is less massive than the Ring Nebula's progenitor star, so it will not have an opulent ending.

"When the sun becomes a white dwarf, it will heat more slowly after it ejects its outer gaseous layers," O'Dell said. "The material will be farther away once it becomes hot enough to illuminate the gas. This larger distance means the sun's nebula will be fainter because it is more extended."

In the analysis, the research team also obtained images from the Large Binocular Telescope at the Mount Graham International Observatory in Arizona and spectroscopic data from the San Pedro Martir Observatory in Baja California, Mexico.

Kerry says Israelis, Palestinians must make tough decisions

By Arshad Mohammed

TEL AVIV (Reuters) - Israeli and Palestinian leaders must decide soon on whether to revive long-dormant peace negotiations to end their decades-old conflict, U.S. Secretary of State John Kerry said on Friday.

Ending two days of meetings in the region, Kerry said he had had "very productive" talks. But there were no obvious signs of any breakthrough, with neither side offering the sort of compromises needed to end a three-year stalemate.

"We are reaching the time where leaders need to make hard decisions," Kerry said at the end of his fourth visit to the region in barely two months as he struggles to overcome deeply entrenched positions that have snarled the peace process.

British Foreign Secretary William Hague, who has held separate talks in Israel and the Palestinian territories to voice support for Kerry, told reporters in Jerusalem he had not yet seen any significant progress.

"I don't think we are in a position to say that the necessary compromises have been made," he said.

"Unless bold leadership is there to make the most of this opportunity, then we face a bleak situation in the Middle East," he added, warning that time was running out to secure an independent nation for the Palestinians.

The Palestinians have repeatedly said they will only resume negotiations if Israel halts settlement building on land seized in the 1967 Middle East War, where it wants to establish its future state.

OUTPOST ANGER

The Israeli government has said there should be no preconditions and drew anger earlier this month when it turned to the courts to try to legalize four unauthorized West Bank settler outposts.

Kerry said he had raised the issue with Israeli Prime Minister Benjamin Netanyahu, whose center-right government includes many fervently pro-settler politicians.

"It is also clear that when actions are taken, whether by court or otherwise, it is our view that those actions can be deemed by some to be provocative...So it is our hope that there will be a minimal effort there," Kerry said.

On taking office in 2009, U.S. President Barack Obama called on Israel to halt its settlement program. Netanyahu agreed to a partial freeze, but did not extend it beyond an initial 10-month period and Washington quietly dropped the demand.

Obama made his first official visit to Jerusalem this March to re-launch U.S. peace efforts, with Palestinian officials talking about a June 7 cut-off point for the U.S.-led diplomacy.

The Palestinians say it is pointless to hold negotiations while the Israeli building continues in the West Bank and east Jerusalem - home to some 500,000 settlers.

In the absence of formal peacemaking, the Palestinians last year gained de-facto statehood recognition at the United Nations. Israel is worried that they will use their new-found status to join the International Criminal Court and pursue war crimes charges against the Jewish state.

EU and U.S. diplomats have warned that the spread of the settlements could prove irreversible and Kerry has said the window of opportunity for securing an historic peace deal might close within two years.

"I made clear in my discussions that the parties should be focused on making progress toward...direct negotiations," he said on Friday, adding that each side needed to "refrain from provocative rhetoric or actions ... that take us backwards."
