LAS CRUCES >> The man accused of robbing a credit union Wednesday admitted to the crime, telling an investigator that he was suicidal and hoped police would shoot and kill him inside the financial institution, according to a complaint filed Friday in federal court.
Dominic Holland, 26 of Las Cruces, told a Las Cruces Police officer and FBI task force agent that he robbed the First Light Federal Credit Union on Wednesday morning. He had passed a note to a teller, then ran out of the bank with nearly $5,000.
Holland's initial appearance is set for Monday in federal court. He is being held at the Do?a Ana County Detention Center.
While he was inside the credit union, Holland said, he talked to a college professor who recognized him. Holland asked the professor to leave because "something bad was going to happen," according to the complaint. The professor stayed, and Holland knew he would be caught, he told investigators.
Holland ran to a nearby apartment complex, where he had been known to stay. LCPD officers found him there, and authorities accounted for all the missing cash.
Former White Stripes singer Jack White has provided an answer in court to his former wife Karen Elson, who had a restraining order issued against him last week and has petitioned that he submit to a psychiatric exam.
Rolling Stone obtained court documents from Davidson County Circuit Court in Nashville in which White objects to being characterized as an unfit father to their two children. In the countermotion, his lawyer Cathy Speers Johnson writes, "The reason for filing this response is that Mr. White does not want to be portrayed as something he is not, violent toward his wife and children."
The note also refers to emails the pair sent one another, including one dated May 19, 2013, where she calls him an "amazing father." The motion for a psychiatric exam is described as "inflammatory . . . . disingenuous, fraudulent and retaliatory and simply designed to malign him in the public record or to gain an upper hand in this litigation."
He said he did not oppose the restraining order, but objected to limited communication with his children.
White noted that Elson left the children in his care after signing the restraining order affidavit and then went on a "work/pleasure trip" in New York. "One who was truly fearful of another would not leave their children alone with that person for 10 days," the response noted. "The truth of the matter is that Ms. Elson is not fearful for herself or the parties' minor children."
In Elson's filing, she had referred to a musician White had particular enmity toward ? going so far as to wanting to have his child removed from a class where that musician's child was also taking part ? and White's countermotion revealed that the singer in question was The Black Keys' Dan Auerbach.?
In one email, writes?The Hollywood Reporter, White called Aeurbach a "derogatory name" and said he didn't want to spend the next 12 years of their children's schooling "with people trying to lump us together."
White's spokesperson told THR that he would only comment in court filings on the case, and Auerbach's spokesperson said he had no comment. Auerbach?is also going through a divorce, as announced in February.

Merino High School students Jonny Stahley and Mike Pomeroy, who were both enrolled in the Secondary Automotive Technology program at Northeastern Junior College this past spring, recently competed in the state-wide Skills USA contest.
Pomeroy placed 17th overall and Stahley placed 19th out of 35 competitors from all areas of Colorado. The two had previously placed at the top of the district contest to earn their way to the larger state competition.
In the state's Ford AAA contest, Stahley and Pomeroy as a team finished second overall in the written portion of the testing, out of 150 students. The duo placed sixth in the hands-on part of the contest. During the hands-on portion, experts deliberately put some "bugs" in the engine or other operating systems and it is up to the students to find out what is wrong with the car, working against time.
To help Stahley and Pomeroy prepare for the competition, Mike Schadegg from Wolf Auto in Sterling temporarily donated a 2013 Ford Focus to the college for the students to train on before they went to compete at the state level in mid-May in Denver. For many years, Wolf Auto and Jim Able from Ford AAA Colorado have supported the automotive programs at Northeastern with the donation of cars, advice, and other resources.

Disorder can improve the performance of plastic solar cells, Stanford scientists sayPublic release date: 4-Aug-2013 [ | E-mail | Share ]

Scientists have spent decades trying to build flexible plastic solar cells efficient enough to compete with conventional cells made of silicon. To boost performance, research groups have tried creating new plastic materials that enhance the flow of electricity through the solar cell. Several groups expected to achieve good results by redesigning pliant polymers of plastic into orderly, silicon-like crystals, but the flow of electricity did not improve.
Recently, scientists discovered that disorder at the molecular level actually improves the polymers' performance. Now Stanford University researchers have an explanation for this surprising result. Their findings, published in the Aug. 4 online edition of the journal Nature Materials, could speed up the development of low-cost, commercially available plastic solar cells.
"People used to think that if you made the polymers more like silicon they would perform better," said study co-author Alberto Salleo, an associate professor of materials science and engineering at Stanford. "But we found that polymers don't naturally form nice, well-ordered crystals. They form small, disordered ones, and that's perfectly fine."
Instead of trying to mimic the rigid structure of silicon, Salleo and his colleagues recommend that scientists learn to cope with the inherently disordered nature of plastics.
Speedy electrons
In the study, the Stanford team focused on a class of organic materials known as conjugated or semiconducting polymers chains of carbon atoms that have the properties of plastic, and the ability to absorb sunlight and conduct electricity.
Discovered nearly 40 years ago, semiconducting polymers have long been considered ideal candidates for ultrathin solar cells, light-emitting diodes and transistors. Unlike silicon crystals used in rooftop solar panels, semiconducting polymers are lightweight and can be processed at room temperature with ink-jet printers and other inexpensive techniques. So why aren't buildings today covered with plastic solar cells?
"One reason they haven't been commercialized is because of poor performance," Salleo said. "In a solar cell, electrons need to move through the materials fast, but semiconducting polymers have poor electron mobility."
To find out why, Salleo joined Rodrigo Noriega and Jonathan Rivnay, who were Stanford graduate students at the time, in analyzing more than two decades of experimental data. "Over the years, many people designed stiffer polymers with the goal of making highly organized crystals, but the charge mobility remained relatively poor," Salleo said. "Then several labs created polymers that looked disordered and yet had very high charge mobility. It was a puzzle why these new materials worked better than the more structured crystalline ones."
X-ray analysis
To observe the disordered materials at the microscopic level, the Stanford team took samples to the SLAC National Accelerator Laboratory for X-ray analysis. The X-rays revealed a molecular structure resembling a fingerprint gone awry. Some polymers looked like amorphous strands of spaghetti, while others formed tiny crystals just a few molecules long.
"The crystals were so small and disordered you could barely infer their presence from X-rays," Salleo said. "In fact, scientists had assumed they weren't there."
By analyzing light emissions from electricity flowing through the samples, the Stanford team determined that numerous small crystals were scattered throughout the material and connected by long polymer chains, like beads in a necklace. The small size of the crystals was a crucial factor in improving overall performance, Salleo said.
"Being small enables a charged electron to go through one crystal and rapidly move on to the next one," he said. "The long polymer chain then carries the electron quickly through the material. That explains why they have a much higher charge mobility than larger, unconnected crystals."
Another disadvantage of large crystalline polymers is that they tend to be insoluble and therefore cannot be produced by ink-jet printing or other cheap processing technologies, he added.
"Our conclusion is that you don't need to make something so rigid that it forms large crystals," Salleo said. "You need to design something with small, disordered crystals packed close together and connected by polymer chains. Electrons will move through the crystals like on a superhighway, ignoring the rest of the plastic material, which is amorphous and poorly conducting.
"In some sense, the synthetic chemists were ahead of us, because they made these new materials but didn't know why they worked so well," he said. "Now that they know, they can go out and design even better ones."
And Salleo offered a final piece of advice. "Try to design a material that can live with as much disorder as possible," he said. "Take the disorder for granted. Personally, I really like disorder. Just look at my office."
