A team of 14 Los Alamos High School students and 10 adult mentors built a robot that can shoot hoops. The team began work Jan. 7 and wrapped up the project Feb 21.

The group is competing in the FIRST Robotics Competition. The competition involves short games played by robots. The students build and program their robots, which are remotely controlled during the competition.

Each team receives a kit of parts made up of motors, batteries, a control system, a PC and a mix of automation components – but no instructions. Designing and programming the robot is up to the students.

This year’s competition is Rebound Rumble. The object is to manipulate the robot to score as many baskets as possible during a two-minute and 15 second match.

The competition also includes a balancing component in which the robots are required to balance on a bridge.

The group is heading to Salt Lake City March 15 to compete in the regional round of the competition.

Los Alamos Historical Society News:


John Hopkins

Dr. John C. Hopkins will speak at 7:30 p.m. Tuesday at Fuller Lodge on “The Cold War and U.S. Nuclear Weapons: From My Perspective” as part of the Los Alamos Historical Society’s 2011-2012 lecture series.

“Nuclear weapons, and hence Los Alamos, played a major role during the Cold War.

Immediately after World War II, the task at Los Alamos was to rebuild the staff following the mass exodus that took place with the surrender of Japan.

Hostility with the Soviet Union, that had origins going back to the Russian Revolution, was exacerbated by Soviet belligerence in Europe following the War.

Consequently the United States looked to nuclear weapons to counter the vast land army of the Soviet Union.

The world changed in August 1949 when the Soviet Union had their first nuclear test.

The 1950s witnessed enormous changes in nuclear weapons and the rationale for their use.

These were the golden years for Los Alamos when the lab enjoyed strong support in Washington.

Numerous technical advances were made from the development of very small weapons to the very largest hydrogen bombs.

The 1960s saw an evolution in nuclear weapons policy and, toward the end of the decade, the beginning of a long downward trend in the numbers of weapons in the stockpile.

The 1970s and ‘80s saw the development of the most sophisticated weapons with reduced weight, size and use of nuclear materials.

Finally the Cold War came to an end in the 1990s and Los Alamos started a new chapter in a long and distinguished history.”

Hopkins is a nuclear physicist with a 1960 Ph.D. from the University of Washington in Seattle and a Fellow of the American Physical Society with over 40 publications.

He retired in December 1993, after 34 years at Los Alamos National Laboratory researching nuclear physics, performing and leading nuclear weapons testing, and then as leader of the entire nuclear weapons program at Los Alamos.

He was leader of the Center for National Security Studies at Los Alamos and a technical advisor to the Arms Control and Disarmament Agency in Washington and in Geneva.

Hopkins has worked closely with the State, Energy, and Defense Departments and has participated in numerous special programs for the U.S. Government.

This year, the Centennial Lecture Series celebrates 100 years of Los Alamos History and New Mexico Statehood. Lectures are the second Tuesday of the month at 7:30 p.m. in the Pajarito Room of Fuller Lodge. Lectures. The lectures are free and open to the public, because of the generosity of Los Alamos National Bank and the donations of members of the Historical Society.

The 14 & Under under New Mexico State Short Course Swim Meet was held Feb. 24-26 at West Mesa Aquatic Center in Albuquerque.

Eighteen teams from across New Mexico participated in the 3-day event and 112 different events were raced.

Nine swimmers from the Charger Aquatics – Los Alamos (CAQ-LA) team helped cinch the win that brought the 14 & Under state banner back to Los Alamos. CAQ-LA is a branch of Albuquerque Academy’s Charger Aquatics.

From Kaan Unal, Sarah Lott, Sam Harris, Maria Venneri, Sara Shiina and Radhika Iyer.

The branch team was started in September 2010 with one senior swimmer. In April 2011 it started an age group program and has grown to 20, ages 6 and over.

Kaan Unal (12) led the pack placing in the top 8 in seven individual events as well as four relays.  Maria Venneri (14) was top 10 in six individual events as well as 5 relays.  Sarah Lott (14) and Sara Shiina (12) both placed in the top 10 in five of the seven individual events they swam as well as the 5 relays Lott and 4 relays Shiina participated.

Radhika Iyer (12) and Presley Gao (9) also added to the team point totals with their individual and relay swims.  New state meet qualifiers Katherine Elton(9), Injie Mourad (9) and Takuma Shiina (9) had fun with great swims and cheering on their teammates.

Family Strengths Network News:

Adolescence is a critical developmental time for every family.

While young people are learning to use their emerging independence to discover their strengths, parents look for opportunities to balance their child’s need for freedom with guidance and direction.

Proactive families know that while children don’t come with a handbook, there are local resources to facilitate a positive experience for everyone during this period of growth.

Family Strengths Network (FSN) is providing a record number of programs for tweens, teens, and their parents this spring.

For families who are ready to meet this transition with education, a good sense of humor, and pizza, FSN offers Tweens to Teens for Girls March 13 and Tweens to Teens for Boys March 20.

Dr. Tom Csanadi and LAPS teacher Scott Johnson lead discussion and activities with boys aged 11 – 14 and their fathers or other male adult.

Public Health Nurse Megan Pfeffer and educator Jennifer Bartram address the changes puberty brings with girls ages 9 – 13 and their mothers or other female adult.

These workshops help take the “squirm factor” out of communicating about adolescence.

In Girls Circle, middle school and high school students use discussion and crafts to express themselves and learn to think independently.

This empowering group meets Mondays from March 5 – April 30.

High school girls meet 3:30-5 p.m. at FSN. Eighth grade girls meet during lunch at LAMS.

The program will provide eighth graders with lunch and high school kids with refreshments. The Juvenile Justice Advisory Board is funding the Circle programs.

Reduce, reuse, and save at the Prom Dress Swap, 10 a.m.-2 p.m. March 24 at FSN.

Drop off donations at the Teen Center or FSN for a $5 coupon toward your new dress. The Key Club is co-sponsoring this event.

The Parents of Teens Breakfast Group will meet from 7:30 8:30 a.m. at The Coffee Booth on Tuesday mornings April 17 – May 8.

Early risers can purchase breakfast and get tips on avoiding power struggles and navigating changes in family dynamics.

Jennifer Bartram will use Active Parenting of Teens, a powerful evidence-based tool, to facilitate discussion. The DWI Council is funding this event.

For more information and online registration for these and other programs including Parenting with Love and Logic for families of school age kids and Ages of Discovery for families with newborns through age five, visit www.lafsn.org.

Family Strengths Network, 1990 Diamond Dr., 662-4515, is a private, non-profit organization and a United Way Community Partner.

Time to Change Batteries in Smoke and CO Alarms this Weekend

Los Alamos Fire Department News:

Daylight Saving Time begins Sunday and the U.S. Consumer Product Safety Commission (CPSC) is urging consumers to replace the batteries in their smoke and carbon monoxide (CO) alarms this weekend.

Fresh batteries allow smoke and CO alarms to do their jobs saving lives by alerting families of a fire or a buildup of deadly carbon monoxide in their homes.

CPSC estimates there was a yearly average of 386,300 residential fires resulting in nearly 2,400 deaths between 2006 and 2008.

Two-thirds of fire deaths occur in homes where there are no smoke alarms or no working smoke alarms.

That is why it is important to replace batteries at least once every year and to test your alarms every month to make sure they work.

CPSC recommends consumers have smoke alarms on every level of their home, outside bedrooms and inside each bedroom.

CPSC estimates there was an annual average of 183 unintentional non-fire CO poisoning deaths associated with consumer products between 2006 and 2008.

CO is called the “invisible killer,” because it is a colorless, odorless and poisonous gas.

Because of this, people may not know they are being poisoned. Carbon monoxide is produced by the incomplete burning of fuel in various products, including furnaces, portable generators, fireplaces, cars and charcoal grills.

That is why it is important to have working CO alarms in the home, on each level and outside each sleeping area.

Ice, Mud, and Spring Fever

Craig Martin

April is the cruelest month, breeding lilacs out of the dead land, mixing memory and desire…” T. S. Eliot, The Wasteland.

For a Los Alamos resident who lives to be outside, March is the cruelest month. Once or twice a week, the weather hints of the end of winter and I get a touch of spring fever. I have to get on a trail as often as possible.

But on the higher terrain above town, the snow is alternately slush and rock-hard ice, not ski conditions I dream about on autumn nights. In town, the snow is hard-packed into icy ribbons on the trails, and when it melts, the trail turns to a goo that is slicker than the ice. I’m spoiled by the Los Alamos trail network and I really balk at walking on the sidewalk.

My profession of trail caretaker further complicates the simple act of taking a trip out the door. I know this muddy season has the potential to affect long-term trail conditions by trenching the trail a little deeper and by widening beautiful, skinny singletracks.

Potholes left by bootprints and ruts gouged by mountain bike tires when the soil is slick often linger until summer. Over time, they get worn down by trail traffic, but at the expense of the trail. The trail tread is worn to dust, which is carried away by wind or water. As a result, the trail becomes a trench that deepens just a little bit each season.

Widening trails occurs when users try to avoid muddy stretches by traveling next to the trail. Vegetation is most vulnerable to compaction when it is dormant, so repeated stepping or riding on trailside grasses and wildflowers is likely to kill them.

To avoid causing problems to a trail while meeting my need for blue sky above, I adjust my routine to trail conditions or I seek trails where my impact is minimal.

  • When I walk on a snow-packed or icy trail, I use traction devices on my boots. This permits me to stay on the ice and avoid walking along side the trail.
  • I take an early trip—at 6 a.m., the mud is frozen.
  • Trails on south-facing slopes and mesa tops dry out first.
  • Trails that have a lot of rock surface don’t have much mud.
  • My mountain bike stays in the garage.
  • White Rock, here I come.

There are plenty of good choices for a walk right now. Here are some current trail conditions:

Trails generally free of ice and mud include the Quemazon, Mitchell, Woodland, and the eastern part of the Perimeter.

Kwage Mesa is in good shape, but Deer Trap Mesa still has some muddy spots.

Bench trails on the north sides of canyons are good: the North Bayo Bench Trail, and the North Pueblo Bench Trail.

Trails in White Rock are in good shape, including the Blue and Red Dot trails, and the trails on Department of Energy lands south of White Rock.

There’s no excuse for watching another You Tube video, get out there and soak in those fleeting hints of spring.

Diverse Faiths Share Soup and Spirituality

The first Lenten Soup Supper took place last Thursday at Trinity on the Hill Episcopal Church and drew a diverse crowd of local Episcopalians, Lutherans, Jews, Methodists, United Church members and others. Those gathered enjoyed a free meal of homemade soups and breads, were inspired by four different teaching sessions, and ended the event by joining together in a brief evening prayer service. The Lenten Soup Supper events will continue at 6 p.m. every Thursday, including this evening, through March 29. Everyone is welcome to stop by the TOTH Parish Hall at 3900 Trinity Dr., at the corner of Diamond and Trinity, to partake in savory soups, breads sure to warm the cockles of most hearts and a gentle dose of spiritual edification.

The People Spoke and the School Board Listened

By Kirsten Laskey

The public came, they talked and they were heard at Tuesday night’s special school board meeting in the Speech Theater at Los Alamos High School.

After hearing strong opposition to the recently approved bus-loop along Diamond Drive for Los Alamos High School, the board unanimously approved putting the brakes on the project pending further investigation.

The board’s decision resulted in several “thank yous” from the crowd.

Superintendent Gene Schmidt said conversations on the bus loop began four to five months ago.

There were initially seven proposals, which were “whittled down” to two:

  • Reconfiguring the parking lot adjacent to Duane Smith Auditorium to include a bus lane.
  • Building a bus loop along Diamond Drive.

The board aired a short traffic video, which revealed buses, cars and pedestrians attempting to maneuver around each other in the Duane Smith parking lot.

Student safety is the purpose behind this project, Schmidt said. Mornings and afternoons at the parking lot are like “organized chaos.”

Board President Melanie McKinley added that the Public School Finance Authority has specific guidelines about separating school buses from other traffic.

The board approved the Diamond Drive bus loop option during its Dec. 21 meeting.

The option would have buses entering the loop near the “jock lot” by Griffith Gymnasium and exiting close to the entrance of the Duane Smith parking lot. The loop would hold up to six buses at a time.

“We wanted to create a bus zone that was safe and inviting and directed people to the main entrance,” Schmidt said.

However, two trees would need to be cut down for this option and the entrance and exit may conflict with the “jock lot” exit and the Duane Smith lot entrance.

The bus lane would run up against the auditorium and continue along P Wing. A chain link fence would be erected along the length of the bus lane.

The option would call for restriping existing parking spaces and putting asphalt behind P Wing along Orange Street. Some parking spaces in the lot would be lost.

The estimated cost for the Duane Smith parking lot option is $190,000.

The Diamond Drive loop is estimated to be $155,000. Neither option includes landscaping costs.

The project would be partly funded by a $39,000 grant from the New Mexico Department of Transportation, Schmidt said.

During public comment, Magistrate Judge Pat Casados, speaking as a Denver Steels resident, asked the board to consider the impact the options would have on the neighborhood. Already parents driving their kids to school are a problem, she said, adding that many are rude and inconsiderate on the road.

“I hear the (vehicles) screeching every morning,” she said.

If parking spaces are eliminated from the Duane Smith Parking lot, then more drivers will park on residential streets, Casados said.xz

“I’m asking you to stop, think and be a good neighbor,” she said.

Audience member Elaine Jacobs wondered whether there was another alternative such as using Sullivan Field for buses.

Board Member Dawn Venhaus said this would not work because the Sullivan Field parking lot is county-owned.

Another audience member commended the board on its hard work and complimented the new wing at the high school. However, putting in a bus loop would end the project on the wrong note, he said.

“If you put in a bus lane … you’re just not finishing it right,” he said.

He urged the board to “leave the grass, leave the trees.”

A number of Los Alamos High School students stepped forward to voice their opposition to the Diamond Drive option. One student presented a petition containing 141 signatures from her peers urging the board to strive for alternative options.

The board agreed that more work was needed to be done.

Board Vice President Kevin Hornell said a smarter solution needed to be produced.


Los Alamos High School Bus Loop Options
The bus loop options have been a topic of discussion at the 11/8/11 and 12/20/11 Regular School

Gray Fox Facts


All four deserts of the American Southwest and beyond.


Chaparral, wooded areas and among boulders on the slopes of rocky ridges in canyons and open desert.


The Gray Fox is the only member of the dog family that can climb trees, usually to seek refuge or in search of roosting birds. It can reach a speed of 28 mph for short distances and has lived for up to 10 years in captivity; longevity in the wild is probably much shorter.

The Gray Fox is smaller in size than the Coyote – usually 32 to 45 inches long, and weighs seven to 11 pounds. Its coloration is grizzled gray on top, with a white throat extending underneath; it is rusty-red along the sides. The tail usually has a black mane along the top, with a dark-gray or black tip. Gray Foxes have elongated muzzles and forward-pointing ears.

Although primarily nocturnal, The Gray Fox may sometimes be seen foraging during the day, seeking primarily small mammals, but being an omnivore, it will also eat eggs, insects, birds, fruits, acorns and berries.

If not using a hollow tree, the vixen (female) may dig her den into soil or enlarge the burrow of another animal. This den may be as much as 75 feet long and can have 10 or more exits. There are also numerous side chambers used for food storage and for the transfer of young, once a chamber becomes too soiled to inhabit.

Life Cycle:

The Gray Fox mates in February or March, bearing young in April or May – a gestation period of about 51 days. The three to seven pups are dark brown in color; they are born blind and remain so for about 10 days. The young venture out of the den after about five weeks, and are usually weaned by 10 weeks. The father provides food for the entire family during this period. The family remains together until late fall, then separates. All foxes generally remain solitary throughout the winter.

The other three species of foxes in the U.S. are the Red Fox (Vulpes fulva), the Kit Fox (Vulpes macrotis) and the Swift Fox (Vulpes velox), each of which is about half the size of the Gray Fox. The Red Fox has the largest range in North America, but occurs only in the Chihuahuan Desert of eastern New Mexico. The Kit Fox occurs in all four southwestern deserts, while the Swift Fox generally does not occur in any desert environments.
