Texas man found guilty in wrongful conviction case

SAN ANGELO, Texas (AP) ? A West Texas jury on Wednesday convicted a man for the murder of an Austin woman whose husband was wrongfully convicted of her slaying and spent nearly 25 years in prison before being exonerated.

Jurors in San Angelo found Mark Alan Norwood guilty of capital murder for the 1986 killing of Christine Morton, who was attacked in her north Austin home. Prosecutors said Norwood beat the woman to death.

He was sentenced to life in prison, but is eligible for parole after 15 years. Jurors deliberated for about three hours before returning their verdict.

Morton's husband, Michael, was initially convicted in her death in 1987, but he was exonerated and freed in 2011 after new DNA testing was done on a bloody bandanna found near the couple's home. Investigators said the DNA evidence led them to Norwood, whose DNA was in a national database as a result of his long criminal history.

Michael Morton hugged Norwood's mother outside the courtroom after the trial. He also hugged Norwood's brother, Dale.

Morton told the Austin American-Statesman that what he was feeling was "a mixed bag. It's not a celebration, and it's not a happy day."

"Michael and his family are pleased that justice, at last, has been provided for the memory of Christine Morton," John Raley, Morton's Houston-based attorney, said in an email. Raley spent years working for free on the case after teaming up with the Innocence Project.

Texas Attorney General Greg Abbott, whose office handled Norwood's prosecution, said no verdict can bring back Christine Morton's life or "recover the devastating years that her husband Michael Morton spent unjustly imprisoned for her murder."

"We can only hope that today's verdict provides some much-deserved, but woefully delayed justice for a family that suffered so terribly for so long," Abbott said in a statement.

Norwood's sister, Connie Hoff, said her brother had been railroaded because prosecutors had introduced evidence from the 1988 death of Debra Masters Baker in Austin during the trial. Norwood, 58, also has been charged with capital murder in the death of Baker, who lived near the Mortons.

Hoff said her family is now going through what the Morton family went through when he was convicted.

"This is history repeating itself," she told the American-Statesman.

During closing arguments earlier Wednesday, prosecutor Lisa Tanner told jurors they need to convict Norwood "and not let evil walk out of this room with you."

One of Norwood's lawyers, Ariel Payan, suggested to jurors during closing arguments that the evidence gathered from the bandanna was contaminated.

DNA testing wasn't available when the blood on the bandanna was initially tested in 1986. The testing wasn't done until Michael Morton's attorneys spent years lobbying for it.

Prosecutors also told jurors that a gun Norwood stole from the Mortons' home and later sold linked him to the murder. Morton testified at the trial, telling jurors about the missing gun.

The trial was held in San Angelo after being moved from Williamson County, near Austin, because of publicity in the case. The Texas Attorney General's Office was not seeking the death penalty.

Last month, a special hearing known as a court of inquiry was held to examine whether state District Judge Ken Anderson acted improperly in 1987 when, as Williamson County district attorney, he prosecuted Michael Morton. Morton's lawyers have accused Anderson of intentionally hiding evidence.

Anderson has denied any wrongdoing. A decision by a judge on whether Anderson should face criminal charges in the case might come next month. Anderson also is being sued by the State Bar of Texas for his conduct in the Morton case.

Britain's domestic spy agency names new director

LONDON (AP) ? Britain's domestic spy agency has chosen a new director, a 50-year-old ornithologist with counter-terrorism experience in the Middle East and Northern Ireland.

Andrew Parker, one of the youngest MI5 directors in recent history, has worked for the service for 30 years and led the agency's response to the July 7 London transit bombings in 2005.

Parker said Thursday that he's "extremely proud of the extraordinary work the men and women of MI5 do to keep the country safe in challenging circumstances," and that he looks "forward to leading the service through its next chapter."

Parker has been the deputy director general since 2007.

He succeeds Jonathan Evans, who is leaving MI5 after 33 years of service. He starts his job on April 22.

New fossil species from a fish-eat-fish world when limbed animals evolved

Thursday, March 28, 2013

"We call it a 'fish-eat-fish world,' an ecosystem where you really needed to escape predation," said Dr. Ted Daeschler, describing life in the Devonian period in what is now far-northern Canada.

This was the environment where the famous fossil fish species Tiktaalik roseae lived 375 million years ago. This lobe-finned fish, co-discovered by Daeschler, an associate professor at Drexel University in the Department of Biodiversity, Earth and Environmental Science, and associate curator and vice president of the Academy of Natural Sciences of Drexel University, and his colleagues Dr. Neil Shubin and Dr. Farish A. Jenkins, Jr., was first described in Nature in 2006.This species received scientific and popular acclaim for providing some of the clearest evidence of the evolutionary transition from lobe-finned fish to limbed animals, or tetrapods.

Daeschler and his colleagues from the Tiktaalik research, including Academy research associate Dr. Jason Downs, have now described another new lobe-finned fish species from the same time and place in the Canadian Arctic. They describe the new species, Holoptychius bergmanni, in the latest issue of the Proceedings of the Academy of Natural Sciences of Philadelphia.

"We're fleshing out our knowledge of the community of vertebrates that lived at this important location," said Downs, who was lead author of the paper. He said describing species from this important time and place will help the scientific community understand the transition from finned vertebrates to limbed vertebrates that occurred in this ecosystem.

"It was a tough world back there in the Devonian. There were a lot of big predatory fish with big teeth and heavy armor of interlocking scales on their bodies," said Daeschler.

Daeschler said Holoptychius and Tiktaalik were both large predatory fishes adapted to life in stream environments. The two species may have competed with one another for similar prey, although it is possible they specialized in slightly different niches; Tiktaalik's tetrapod-like skeletal features made it especially well suited to living in the shallowest waters.

The fossil specimens of Holoptychis bergmanni that researchers used to characterize this new species come from multiple individuals and include lower jaws with teeth, skull pieces including the skull roof and braincase, and parts of the shoulder girdles. The complete fish would have been 2 to 3 feet long when it was alive.

"The three-dimensional preservation of this material is spectacular," Daeschler said. "For something as old as this, we'll really be able to collect some good information about the anatomy of these animals."

The research on Holoptychius bergmanni was led by Downs, a former post-doctoral fellow working with Daeschler who also teaches at Swarthmore College. Other co-authors of the paper with Downs and Daeschler are Dr. Neil Shubin of the University of Chicago, and the late Dr. Farish Jenkins, Jr. of Harvard University, who passed away in 2012.

Honoring a Modern Arctic Explorer and Supporter of Science

The researchers named the new fossil fish species Holoptychius bergmanni in honor of the late Martin Bergmann, former director of the Polar Continental Shelf Program (PCSP), Natural Resources Canada, the organization that provided logistical support during the team's Arctic research expeditions spanning more than a decade. Bergmann was killed in a plane crash in 2011 shortly after the team's most recent field season in Nunavut.

"We decided to choose Martin Bergmann to honor him, not ever having met him, but with the understanding that his work with PCSP made great strides in opening the Arctic to researchers," said Downs. "It's an invaluable project happening in the Canadian Arctic that's enabling this type of work to happen."

Bergmann's organization assisted the research team with many aspects of expedition logistics including difficult flight operations to carry supplies and research personnel to remote research sites on Ellesemere Island. Daeschler described the pilots as capable of landing a Twin Otter aircraft almost anywhere, as long as the ground was solid ? a condition they tested by briefly touching down the airplane and circling back to see if the tires left a deep mark in the mud.

Daeschler and colleagues intend to return to Ellesemere Island for another field expedition in the summer of 2013 to search for fossils in older rocks at a more northerly field site than the one where they discovered T. roseae and H. bergmanni.

A Deeper Look at the Devonian

Daeschler and a different co-author described another new species of Devonian fish in addition to H. bergmanni, in the same issue of the Proceedings of the Academy of Natural Sciences.

Quantum magnets moving along: Scientists observes coherent propagation of a single spin impurity in a chain of ultracold atoms

Mar. 13, 2013 ? Many discoveries in physics came as a big surprise -- for example the phenomenon, that some materials loose almost all their electrical resistance at low temperatures, or that others become superconductors at unexpectedly high temperatures. In the past it was mainly due to theoreticians to develop models explaining these unusual properties. Unfortunately it is not possible to have a direct look into a solid state crystal and follow up the motion of charge carriers as this process happens at extremely short time and length scales. A team working with Professor Immanuel Bloch (Chair for Experimental Physics at the Ludwig-Maximilians-Universit?t Munich and Director at MPQ) has now observed the coherent propagation of single spin excitations in an ultracold quantum gas of strongly correlated atoms.

This is one of the most fundamental processes in the magnetism of quantum systems. In close collaboration with theoretical physicists from the Ludwig-Maximilians-Universit?t Munich and the University of Geneva the scientists were able to demonstrate that the propagation of the spin wave in less strongly correlated systems is being slowed down by the emergence of quasi-particles, so-called polarons.

Properties of condensed matter such as magnetism, electrical conductivity, or superconductivity are the result of the behaviour of electrons in the periodic crystal of the solid. In this respect, the intrinsic angular momentum, i.e. the spin of the electrons, is playing a key role. For example, the high-temperature conductivity exhibited by a class of cuprates is thought to go back to the spin coupling of strongly correlated electrons. Ultracold atoms in an optical lattice are ideally suited to investigate such quantum magnetic phenomena under controlled experimental conditions.

The experiment starts with cooling rubidium atoms down to temperatures near absolute zero. The ensemble is then kept in a light field which divides it into several parallel one-dimensional tubes along which the atoms are allowed to move. Now the tubes are superimposed with yet another light field, a standing laser light wave. By the periodic sequence of dark and bright areas an optical lattice builds up in which each site is occupied with exactly one atom fixed to its position. This highly ordered state is called a Mott insulator (named after the British physicist Sir Neville Mott). After all, an array of several chains of atoms each containing around 15 atoms is formed.

The atoms in the optical lattice take the role of the electrons in a solid state crystal. They are in a similar way characterized by an intrinsic angular momentum (a spin). However, in this case the scientists have control over the spins which can -- as if they were little magnetic needles -- align in two opposite directions. In the beginning, all spins are pointing into the same direction. Then, one single atom in the centre of each chain is picked out by a laser beam, and its spin is flipped by irradiating microwave pulses. Afterwards the motion of this deterministically generated spin impurity through the chain is followed up.

An imaging technique developed in the group makes it possible to visualize each atom on its particular lattice site with very high resolution. Using this method the position of the spin impurity can be precisely determined for various evolution times. This measurement is performed on all atomic chains at the same time. The emerging distributions exhibit a structure that is characteristic of an interference pattern, as it is expected from the interference of coherent waves. "Our model describes the process of spin propagation by a mechanism called 'correlated super exchange'," Dr. Christian Gro? explains, scientist at the experiment. "The same instance the spin impurity moves one site to the right the neighbouring atom takes its place. As this exchange takes place in the opposite direction at the same time and with the same probability the observed interference pattern results. If the system was a classic one only a broadening of the distribution would have been observed over time. Thereby we have proved that the spin wave propagates coherently."

In the insulating Mott phase the barriers between the lattice sites are very high, and the atoms are tightly bound to their position, except for the case of the correlated super exchange mentioned above. When the height of the barrier, i.e. the intensity of the laser beams, is lowered below a certain threshold, the atoms are allowed by the rules of quantum mechanics to "tunnel" through the barrier and reach a neighbouring site. In this 'superfluid phase' the mobility of the atoms is enhanced, however, the motion of the impurity gets slowed down, as was demonstrated in the measurement. "The tunnelling happening everywhere in the lattice increases the complexity of the interaction of the spin impurity with the background atoms,"

Dr. Takeshi Fukuhara points out, who works on the experiment as a postdoctoral researcher. "In the end, the interaction is repulsive, creating a hole in the distribution of the background atoms." On its way through the chain the spin impurity has to drag this hole all along, that way getting kind of heavy. "This is quite similar to passing a crowd on a subway station: it will take a long time since one has to create the necessary space on each step," Fukuhara says. "The motion of the impurity observed in our experiment is in good agreement with the forming of quasi particles in the lattice, so-called polarons, as they are known from solid state physics."

The results obtained in this series of measurements are of high interest: on the one hand, the experiments demonstrate the outstanding control of ultracold quantum systems that can be achieved at present. This is a precondition for the simulation of collective solid state excitations, which give, for example, rise to quantum magnetic phenomena. On the other hand the measurements give a direct insight into the propagation of charge carriers and impurities in solid state crystals, which in the end determine the macroscopic properties of materials.

V-moda unveils Vamp Verza: a dockable, device-agnostic headphone amp and DAC for mobile audiophiles (update: video)

Vmoda unveils Vamp Verza a dockable, device-agnostic headphone amp and DAC for mobile audiophiles

Last we heard from V-moda, the company was appealing to audiophile sensibilities with its $300 Crossfade M-100 portable headphones. Continuing in that respect, today it's officially unveiling the Vamp Verza as a followup to last summer's $650 iPhone 4/4S-purposed Vamp spy tool headphone amp, DAC & case combo. The aluminum-clad Verza is a device-agnostic solution that uses a sliding dock system with special $100 Metallo cases to give any supported devices a similar all-in-one feel to the original.

At launch, a GS III case is available, with an iPhone 5 model a few weeks out -- the company is aiming to get GS IV and Note II cases out next. The unit's 150mW x 2 amplifier will bypass your iDevice's audio output via a USB port on its bottom, while an adjacent microUSB port can take advantage of the external sound card profile found in Android Jelly Bean. V-moda notes the microUSB port acts like a traditional USB audio device, so it'll work with mostly any device. As you might guess, both ports have their own specific DACs routing audio at different power levels to its op-amp.

TI shows off LaunchPad-based prototype mouse, hints at a big follow-up

TI shows off LaunchPadbased prototype mouse, hints at a big followup

If you've been needing a little inspiration for your next TI LaunchPad project, look no further than the company itself. Texas Instruments set up shop in the maker tent across from the Austin Convention Center this week, showing off creations built atop its line of microcontrollers. The rep we spoke with was particularly excited about this mouse hack that the company put together in a few hours, while getting ready for SXSW. The creation utilizes the Stellaris board's accelerometers to control the cursor of a Windows machine on X, Y and Z axes, via USB.

The project is more than just a hack, according to the company -- it's actually a prototype of something it's set to unveil later this year. No specifics on that front, but TI promised a "big surprise." In the meantime, you can check out video of the project after the break.
