Antarctic scientists discover 18-kilogram meteorite

Feb. 28, 2013 ? An international team of scientists, working at Princess Elisabeth Antarctica research station, have discovered a meteorite with a mass of 18 kilograms embedded in the East Antarctic ice sheet, the largest such meteorite found in the region since 1988.

The eight members of the SAMBA project, from Universit? Libre de Bruxelles (ULB) and Vrije Universiteit Brussel (VUB), Japan's National Institute of Polar Research (NIPR) and Tokyo University were searching for meteorites scattered across the Nansen Ice Field on January 28, when they found the 18kg ordinary chondrite. The team discovered a total of 425 meteorites, with a total weight of 75kg during the 40 day expedition, at an altitude of 2,900m, 140km south of Belgium's Princess Elisabeth Antarctica research base.

"This meteorite was a very unexpected find for us, not only due to its weight, but because we don't normally find such large meteorites in Antarctica," said Vinciane Debaille, a geologist from Universit? Libre de Bruxelles, who led the Belgian part of the team during the expedition. "This is the biggest meteorite found in East Antarctica for 25 years, so it's a very special discovery for us, only made possible by the existence and location of Princess Elisabeth Antarctica."

The SAMBA project contributes to the US and Japan-led global collection of Antarctic meteorites, and is an initiative of VUB and ULB, in collaboration with the Japanese Institute of Polar Research. SAMBA is supported by the Belgian Science Policy (BELSPO) and the International Polar Foundation.

Initial field analysis by the scientists suggests that the 18kg meteorite is an ordinary chondrite, the most abundant kind of meteorite. The fusion crust -- the meteorite's outer casing -- was eroded, allowing the scientists to inspect the rock underneath. The meteorite is currently undergoing a special thawing process in Japan -- to ensure water doesn't get inside the rock.

"We study meteorites in order to better understand how the solar system formed, how it evolved, how the Earth became such a unique planet in our solar system," said Debaille. "This season's SAMBA mission was a success both in terms of the number and weight of the meteorites we found. Two years ago, we found less than 10kg. This year, we found so much that we had to call the travel agency -- because we had 75kg of meteorites to take home."

Princess Elisabeth Antarctica is the world's first zero emission polar research station, and is operated by the International Polar Foundation, in partnership with the Belgian Polar Secretariat. Princess Elisabeth Antarctica's design and construction seamlessly integrates passive building technologies, renewable wind and solar energy, water treatment facilities, continuously monitored power demand and a smart grid for maximising energy efficiency. Located in East Antarctica's S?r Rondane Mountains, Princess Elisabeth Antarctica welcomes scientists from around the world to conduct research in this little-studied and pristine environment.

Strong Words, Vol. 1: New Titles In Health And Fitness

Even the most computer-attached among us can usually point to a book or video that helped put us on the right path in fitness and strength training. Maybe yours was Arnold's New Encyclopedia of Modern Bodybuilding, or a classic Robert Kennedy or Larry Scott title. Perhaps it was an obscure VHS that you wore out, or something you'd rather not admit to, but which still made you feel like you'd "gotten it" for the first time.

Even during the digital age, high-quality books and videos still set the bar when it comes to presenting comprehensive, well-sourced research and innovative training systems. In this new regular feature, we'll run down the latest promising new releases worthy of a place on your nightstand or coffee table. If you're looking for a way to turn your interest in training into a full-fledged education, they'll give you a good idea where to start.

Delavier's Anatomy for Bigger, Stronger Arms
by Frederick Delavier and Michael Gundill
Publisher: Human Kinetics
Price: $24.95

Who it's for: Anyone who believes a muscular physique begins with a strong knowledge of anatomy.

While definitely the most popular group of muscles for people to train, the arms are also the simplest, and they're arguably of much lower importance when compared to the muscles of the hips, legs, back, or core.

So I understand why legendary French illustrator Frederic Delavier, author of Strength Training Anatomy and a host of other titles, chose to focus on the arms in the second of his body part-specific training guides, after 2011's Core Training Anatomy. I just wish he'd hurry up and hit more body parts!

This book is chock-full of high-quality photos and illustrations done by Delavier himself. Demonstrating a deep practical and working knowledge of anatomy and biomechanics, Delavier and co-author Michael Gundill outline everything you need to know to build large, shapely arms.

A beginner can pick up this book and find the exercises, goal-setting guide, and arm workout programs they need to start their journey. Meanwhile, there is plenty of meat for the seasoned trainer, such as an impressive section on selectively training and understanding weak areas, common pathologies, and carryover into sport.

I have never seen a book that covered arm training at such a high level, yet was so simple to follow and beautifully illustrated. Anatomy for Bigger, Stronger Arms is without peer.

Anatomy For Runners: Unlocking Your Athletic Potential for Health, Speed, and Injury Prevention
by Jay Dicharry, MPT, SCS.
Publisher: Skyhorse Publishing
Price: $14.95

Who it's for: Athletes who don't think "runner" needs to be a synonym for "weak" or "slouched".

The sport of running is at a crossroads. On one hand, the chorus of voices in the fitness community advocating sprints and interval training, and dismissing distance running altogether, has never been louder. On the other, extreme feats like ultramarathons are exploding in popularity.

In Anatomy for Runners, Jay Dicharry, the director of the SPEED Clinic and the Motion Analysis Lab at the University of Virginia, offers an "approachable biomechanics text" outlining how one of the foundational human movements has devolved into "some crazy type of badge-of-courage sport in which you have to pound yourself into shape day-in and day-out until you emerge on top."

Lost somewhere among the endless miles runners are logging are basic ideas like form, conditioning, and risk assessment, all of which runners ignore at their own peril, Dicharry writes.

Stunningly, more than 80 percent of runners will sustain a running-related injury at some point in their lifetime, yet as he points out, the act of running itself has never been clinically proven to be bad for you. In response, Dicharry recalls his own checkered history with running and injury before laying out "how the musculoskeletal system responds to running, and how to optimize this relationship."

In a slim volume priced less than a bestselling novel, he offers up well-illustrated mobility and stability tests to assess form, corrective exercises to improve flexibility and strength?including weightlifting?and principled tips in regard to footwear, stretching, and trends like barefoot running.

While he seems to favor a minimalist or barefoot approach to running, Dicharry also grants that heel-strikers can run without injury, and offers recommendations to help them do so. That may seem a small concession, but by bringing them in, he succeeds in making Anatomy for Runners a necessary title for runners of all stripes.

Power Speed Endurance: A Skill-Based Approach to Endurance Training
by Brian MacKenzie
Publisher: Victory Belt Publishing
Price: $39.95

Who it's for: Enterprising home-CrossFitters who both sprint and go the distance.

Like Jay Dicharry, Brian MacKenzie treats running and other endurance sports as skills that should be developed strategically, rather than simply by piling on volume.

However, MacKenzie, the creator of the CrossFit offshoot CrossFit Endurance, goes far beyond biomechanics in Power Speed Endurance, laying out a total approach to preparing for endurance running, rowing, cycling, swimming, or triathlons. In a large and lavishly illustrated manifesto, MacKenzie goes into deep detail about strength training and conditioning, athletic technique, programming, and even nutrition and performance fueling.

In short, MacKenzie advocates preparation for distance rather than through distance. While long-distance training has a place in his programs, it is something to be worked up to in the long-term. In the short term, "stamina work is done at 80 percent effort or above," in the form of intervals, time trials, technique drills, and CrossFit AMRAP onslaughts.

The goal, he says, is efficiency: "First, master the skill of movement to improve movement efficiency; second, slowly add higher intensity workouts to build strength and test the limitations of your technique; then, once you can maintain technique with intensity, add volume."

A narrative of injury-prevention and overall health runs deep through Power Speed Endurance. Both MacKenzie and T.J. Murphy, who contributes the forward, detail how their experiences with traditional endurance training left them injury-ravaged and fundamentally weakened. CrossFit was their savior, leaving them able to both run a race and walk comfortably afterward.

At about half the price of a monthly membership to a CrossFit gym, MacKenzie's volume is a valuable exercise reference for anyone considering making the change to that system, or to CrossFit Endurance. If you're considering doing those systems on the cheap at home or in a standard gym, the volume is doubly valuable; he offers comprehensive 6-week and 12-week introductory programs, both general and sport-specific.

Raising the Bar: The Definitive Guide to Pull-Up Bar Calisthenics (DVD)
by Al Kavadlo
Publisher: Dragon Door Publications
Price: $29.95

Who it's for: Bodyweight-movement enthusiasts looking for new challenges on the cheap.

You'd probably recognize Al Kavadlo by sight if you've seen one of his 150 or so instructional YouTube videos. In each of them, this lean, tat-covered strength coach calmly explains and performs incredibly difficult bodyweight feats of strength using playground equipment in New York City's Thompson Square Park.

Kavadlo's almost cartoonishly friendly demeanor and his focus on strict progressions make for a welcome contrast to the chest-pounding music video vibe of most other playground workout videos. He clearly wants to teach, not just show what he can do.

In Kavadlo's new DVD, Raising the Bar?a companion to the book of the same name?he lays out detailed progressions for a wide variety of pull-ups, dips, muscle-ups, handstands, and levers. He and his brother Danny (similar tats, but scowling rather than smiling) cover everything from the simple two-arm hang to advanced plyometric moves, ending each short lesson with a short freestyle exhibition showcasing goal movements like fist muscle-ups and behind-the-back clapping pull-ups.

The value of a guide like Kavadlo's is clear for anyone aiming for specific bodyweight goals like a one-armed pull-up or muscle-up. However, it's also valuable simply for preserving the idea that movements and skills, rather than numbers or body markers, are legitimate end goals.

This isn't a system that works if you do it once each week. It needs to be practiced and nurtured over years, but the ultimate reward isn't just strength or body composition. It's a new way to play.

Total Recall: My Unbelievably True Life Story
by Arnold Schwarzenegger
Publisher: Simon & Schuster
Price: $35

Who it's for: Diehard fans looking for the final word on the Austrian Oak.

Being an avid bodybuilding fan for most of my life, I was as giddy as a Japanese school girl rocking a Hello Kitty cosplay at Comic-Con when this was finally published. Total Recall is a revealing look at some of the details of the Austrian Oak's life and career development, offering plenty of memories and anecdotes from his early life that even fans like me missed over the years.

Coming from a damaged post World War II Austria, Arnold views America as a beacon of success and strength and vows to get himself there. He goes unabashedly after what he wants, taking obstacles out of his path with his indomitable will like a heat-seeking missile.

Arriving in America with only a gym bag in hand, Schwarzenegger uses his determination and cunning to build an empire founded on bodybuilding, movies, and business. Many gritty details from his film-making and politics come to light in Total Recall, but predictably, much of the dirty laundry remains hidden, with only glancing mentions of some of the obvious scandals already known to the public.

Having spent more time than most learning about Arnold, this new addition to the Oak's library brings enough new content to make it a worthwhile investment. It is an enjoyable read but feels cautious?you can only wonder what was left out. Maybe instead of Total Recall: My Unbelievable True Life Story it should be titled Total Image Control: The Inspiring Parts of my Life Story.

Wall Street inches up after data

MADRID, Feb 27 (Reuters) - Lionel Messi has rarely been accused of failing to deliver in big games, having scored in two European Cup finals, but after subdued performances against AC Milan and Real Madrid, questions are being asked. The four-times World Player of the Year and leading scorer in one of the greatest club teams of all time, was a shadow of his usual self at the San Siro in a Champions League last-16 first leg last week, when Barcelona slumped to a 2-0 defeat. ...

PFT: Alex Smith to Chiefs? |? Ratto: He'll be missed

JimMillerGetty Images

The fact that the NFL isn?t ready for openly gay players continues to be proven by the words and actions of men who currently occupy, who previously inhabited NFL, and who will be joining NFL locker rooms.

From 49ers cornerback Chris Culliver?s over-the-top rant against gay teammates to Notre Dame Manti Te?o's bizarre ?farrrrrrr from it? response to Katie Courtic?s,? Are you gay?? to Colorado tight end Nick Kasa?s nonchalant reaction on The Dan Patrick Show to the inherently inappropriate ?Do you like girls?? question he faced at the Scouting Combine, it?s obvious that football and homophobia go hand in hand.

Now, a former player who I know and like has joined the fray with an argument that simply doesn?t hold water.? Former NFL quarterback Jim Miller recently told WSCR in Chicago that intolerance is justified by religious beliefs.

?There are some religions that are just not going to accept a gay individual in the locker room,? Miller said.? ?So now, are you as an organization going to bring that element into your locker room and think everything is going to be OK?

?Last time I checked, whether it?s Christianity or Muslims or other religions that are out there, they?re just not going to accept it.? They?re just not.? It?s just not realistic for Mike Florio or any progressive or liberal to think that everything is going to be OK in the locker room and we should all just wise up and accept it.?

Miller separately said he ?could care less? about a teammate?s sexual orientation.? Still, if his position is accurate, then gay coworkers would be rejected in every American workplace.? After all, every American workplace consists of Christians or Muslims or people who practice other religions that, according to Jim Miller, aggressively object to the mere presence of homosexuals on the same payroll.

The problem with most religions is that the relevant scriptures have enough passages that can be isolated and spun to justify pretty much any position someone wants to adopt.? For example, the Old Testament is rife with outdated and confusing rules and regulations.? In contrast, the New Testament is founded on principles like loving one?s neighbor.

For those who believe sexuality is a choice (I don?t), the concept of free will makes matters that occur behind closed doors the business only of the participants and their maker.? For those who believe that sexual orientation is no different than hair color or nose shape (I do), how would Jesus treat such people?? Would He drive out with stones the perverse sexual demons that were hard-wired into their DNA?? Or would He love them and accept them?

But, hey, maybe I?m just taking specific Biblical passages out of context.? I mean, maybe God wants us to reject His creatures for the way He created them.

Arm-in-arm, Ohio students commemorate slain classmates

CHARDON, Ohio (AP) ? One day after a teen gunman pleaded guilty in the deadly school shooting in northeast Ohio, students marked its one-year anniversary Wednesday with hugs, supportive messages and a somber march through town.

The march by Chardon High School students, walking arm-in-arm in the damp cold from the school to the town square, was an emotional highlight during the day's commemoration.

Photos of the three slain students were displayed, onlookers applauded marchers and firefighters hung a large American flag from an aerial ladder.

The march ended at the courthouse where the shooter, T.J. Lane, 18, had pleaded guilty Tuesday to all charges. Lane could face life in prison at his sentencing March 19.

The observance honored Daniel Parmertor and Demetrius Hewlin, both 16, and Russell King Jr., 17, who were killed in the Feb. 27, 2012, rampage. Three others were injured.

Students arriving for classes passed an outdoor school sign with the names of the victims and the message: "2-27 A Day of Remembrance." Across the street, a heart-shaped sign in the school colors of red and black had the message: "One Heartbeat."

The slain students' relatives on Wednesday sued Lane and his family, seeking damages and alleging negligent supervision by his parents and grandparents. Attorneys who filed the case said the families want to ensure Lane never profits from his crimes.

"Hopefully this lawsuit will help answer a lot of questions that still remain and help bring closure for the families and the community," attorneys Peter Marmaros and W. Craig Bashein said.

In Columbus, the Ohio House observed a moment of silence. Rep. John Patterson, who represents Chardon, said he planned to introduce a bill to designate highways in the names of the three victims.

Patterson told his colleagues that they couldn't control tragedies or fully prevent them. And the Jefferson Democrat encouraged parents to tell their children they love them.

The anniversary of the student deaths marks another year of mass shootings around the country ? 12 people gunned down at a Colorado movie theater; six killed at a Sikh Temple in Wisconsin; and 26 Connecticut first-graders and educators slain in Newtown during the Christmas season.

The march in Chardon rekindled memories of the walk taken along the same route by grieving students as they returned to classes three days after the shooting.

A senior student leader, Jessica Mysyk, said the past year has been a time of emotional healing.

"It was hard to even imagine setting foot back into the building where such a tragedy occurred," she told classmates gathered in the square.

Another senior leader, Will Porter, said nothing satisfactorily explains the violent attack.

"There are no explanations I can give that can help any of us understand," he said.

The day's activities in Chardon highlighted the anniversary but served to keep students busy with projects including writing messages of support, artwork, memorial wreaths and making security blankets for future victims of tragedies.

Rachel Loder, 16, who was a sophomore at the time of the Chardon shootings, received such a security blanket and cried and embraced it at difficult times during the past year, her father George Loder said.

"There have been many tears throughout the year," he said.

Loder said his daughter and her classmates have reciprocated by meeting weekly to make blankets, including more than 150 delivered to Newtown.

Counselors and therapists and about a dozen students from Virginia Tech, where a 2007 massacre left the gunman and 32 students and faculty dead, were available throughout the day to meet with students, Chardon principal Andy Fetchik said.

The Virginia Tech students have visited Chardon more than a half dozen times over the past year to promote healing, said Fetchik, wearing a lapel ribbon in the school's red and black colors.

"That's what our kids have been trying to do as they work with that group, is to send that message that one small act of kindness can go a long way," Fetchik said.

Prosecutors say Lane took a .22-caliber pistol and a knife to the school and fired 10 shots at students in the high school cafeteria. Lane was there waiting for a bus to an alternative school he attended.

Lane pleaded guilty to three counts of aggravated murder, two counts of attempted aggravated murder and one count of felonious assault. Charged as an adult, Lane cannot get the death penalty because he was 17 at the time of the crimes.
