Internet sales tax bill advances in Senate

WASHINGTON (Reuters) - Wider U.S. tax collections on Internet sales moved another step closer to reality on Wednesday as legislation in the U.S. Senate cleared another procedural hurdle.

The 75-22 Senate vote cleared the way for consideration of a bill that would empower U.S. states to require out-of-state retailers to collect online sales taxes from customers.

A vote on passage of the measure could come this week.

Supporters include brick-and-mortar retailers such as Wal-Mart Stores Inc and Best Buy Co Inc, as well as cash-strapped state governments.

Amazon.com Inc, which hopes to simplify its U.S. state retail tax situation, also backs the legislation.

Opponents include many online merchants, including eBay Inc and Overstock.com Inc.

Prospects for passage are murky in the Republican-controlled House of Representatives, where some Republicans view it as a tax increase.

Functional potential of genes: Pushing the boundaries of transcription

Apr. 24, 2013 ? Like musicians in an orchestra who have the same musical score but start and finish playing at different intervals, cells with the same genes start and finish transcribing them at different points in the genome. For the first time, researchers at EMBL have described the striking diversity of messenger RNAs (mRNAs) that such start and end variation produces, even from the simple genome of yeast cells. Their findings, published today in Nature, shed new light on the importance of mRNA boundaries in determining the functional potential of genes.

Hundreds of thousands of unique mRNA transcripts are generated from a genome of only about 8000 genes, even with the same genome sequence and environmental condition. "We knew that transcription could lead to a certain amount of diversity, but we were not expecting it to be so vast," explains Lars Steinmetz, who led the project. "Based on this diversity, we would expect that no yeast cell has the same set of messenger RNA molecules as its neighbour."

The traditional understanding of transcription was that mRNA boundaries were relatively fixed. While it has long been known that certain parts of mRNAs can be selectively 'spliced' out, this phenomenon is very rare in baker's yeast, meaning that the textbook one gene -- one mRNA transcript relationship should hold. Recent studies have suggested that things aren't quite that simple, inspiring the EMBL scientists to create a new technique to capture both the start and end points of single mRNA molecules. They now discovered that each gene could be transcribed into dozens or even hundreds of unique mRNA molecules, each with different boundaries.

This suggests that not only transcript abundance, but also transcript boundaries should be considered when assessing gene function. Altering the boundaries of mRNA molecules can affect how long they stay intact, cause them to produce different proteins, or direct them or their protein products to different locations, which can have a profound biological impact. Diversifying mRNA transcript boundaries within a group of cells, therefore, could equip them to adapt to different external challenges.

The researchers expect that such an extent of boundary variation will also be found in more complex organisms, including humans, where some examples are already known to affect key biological functions. The technology to measure these variations across the entire genome as well as a catalogue of boundaries in a well-studied organism are a good starting point for further research. "Now that we are aware of how much diversity there is, we can start to figure out what factors control it," points out Vicent Pelechano, who performed the study with Wu Wei. Wei adds: "Our technique also exposed new mRNAs that other techniques could not distinguish. It will be exciting to investigate how these and general variation in transcript boundaries actually extend the functional capacity of a genome."

Family upset over Air Force officer's transfer

(AP) ? The Air Force's decision to transfer a lieutenant colonel to a Tucson military base after his sexual assault conviction was overturned by a commander has outraged the family of the woman who made the allegations, adding to the growing criticism of the military justice system.

The family says Lt. Col. James Wilkerson' transfer of to Davis-Monthan Air Force Base on the southern edge of Tucson is upsetting because roughly half the woman's family lives there. They're planning a protest Thursday outside the base.

The news comes amid a congressional uproar over the Wilkerson case, and follows heavy criticism of the military's handling of another case involving sex-crime allegations in California.

"They could send him to a number of places," said Stephen Hanks, an orthopedic surgeon in Tucson who is the brother of Wilkerson's accuser. "Why send him to a place where her family lives? It makes no sense."

The woman, a civilian employee who works with service members, accused Wilkerson of sexually assaulting her after a party at his house. Wilkerson and his wife denied the charges but said the woman stayed at their house that night.

A military jury in November convicted Wilkerson, a former inspector general at Aviano Air Base in Italy, of aggravated sexual assault and other charges. He was sentenced to one year in prison and dismissal from the service.

But a commander overturned the verdict and dismissed the charges, saying he found Wilkerson and his wife more believable than the alleged victim. Wilkerson already has reported for duty in southern Arizona, where he will work as a safety officer for the 12th Air Force.

Air Force spokesman Lt. Col. Brett Ashworth said military officials wouldn't have known about the woman's family in Tucson when Wilkerson's transfer was decided.

"His assignment was based on his qualifications and the needs of the Air Force," Ashworth said.

Wilkerson declined an interview request from The Associated Press.

The decision by Lt. Gen. Craig Franklin, commander of the 3rd Air Force at Ramstein Air Base in Germany, to overturn the verdict has been criticized by congressional leaders and advocates for confronting the problem of sexual assaults in the military.

The move led the Defense Department to propose that commanders be largely stripped of their ability to reverse criminal convictions of service members.

Under military law, a commander who convenes a court martial is known as the convening authority and has the discretion to reduce or set aside guilty verdicts and sentences, or to reverse a jury's verdict.

Protect Our Defenders, which advocates for military members who have been sexually assaulted, is calling for Defense Secretary Chuck Hagel to fire Franklin. The group's president, Nancy Parrish, said the Wilkerson case demonstrates that the military justice system needs to be changed.

Commanders who have broad authority in letting cases go forward face a conflict of interest, Parrish said.

"They are incentivized to sweep these cases under the rug. A commander's career is on the chopping block if a rape happens under his or her watch," said Parrish, whose group is pressing the Defense Department on behalf of Wilkerson's accuser.

The military justice system also came under heavy criticism in February, after a former soldier killed two police officers in California.

Records show the Army commander of the former soldier, Jeremy Goulet, allowed Goulet to resign from the military instead of facing a court-martial when he was twice accused of rape. The Army said a lack of evidence prevented it from prosecuting Goulet on charges dating back to 2006.

Critics say Goulet's case is as an example of what can go wrong when military cases are dropped.

Goulet shot and killed two detectives when they went to his house to question him about allegations that he was sexually inappropriate with a former co-worker. Goulet died in the Feb. 26 shootout with police in Santa Cruz, Calif.

Ashworth declined to comment on the group's call for Franklin to be fired. Franklin declined an interview request from the AP.

In a letter to a Pentagon official that surfaced earlier this month, Franklin said a combination of details led to his decision, including that the victim turned down offers to be driven home from the party, didn't accurately describe the house layout and gave a version of events that he didn't find credible. He said Wilkerson was a doting father with a good career, and it would be "incongruent" for him to leave his wife in bed, go downstairs and assault a sleeping woman he'd met earlier that evening.

Protect Our Defenders issued a response to Franklin's letter Tuesday, saying Franklin's account of the woman's options for rides home was inaccurate, Franklin showed blind loyalty toward the accused officer, and that the jury found the woman's story credible.

Scientists provide 'new spin' on emerging quantum technologies

Apr. 23, 2013 ? An international team of scientists has shed new light on a fundamental area of physics which could have important implications for future electronic devices and the transfer of information at the quantum level.

The electrical currents currently used to power electronic devices are generated by a flow of charges. However, emerging quantum technologies such as spin-electronics, make use of both charge and another intrinsic property of electrons ? their spin ? to transfer and process signals and information.??

The experimental and theoretical work, carried out by researchers from York?s Department of Physics, the Institute of Nanoscience in Paris and the University of Missouri-Columbia, USA, could have important implications for spintronics and quantum information technologies.

The team looked at semiconductors? structures ? the base of current electronic devices and of many spintronic device proposals - and the problems created by internal fields known as spin-orbit fields. In general, these tend to act differently on each electronic spin, causing a phenomenon referred to as ?spin-decoherence?. This means that the electronic spins will behave in a way which cannot be completely controlled or predicted, which has important implications for device functionalities.

To address this problem, the scientists looked at semiconductor structures called ?quantum wells? where the spins can be excited in a collective, coherent way by using lasers and light scattering. ?????

They demonstrated that these collective spin excitations possess a macroscopic spin of quantum nature. In other words, the electrons and their spins act as a single entity making them less susceptible to spin orbit fields, so decoherence is highly suppressed.

The theoretical work was led by Dr Irene D?Amico from York?s Department of Physics, and Carsten Ullrich, an Associate Professor from Missouri-Columbia?s Department of Physics. The project began with their prediction about the effect of spin Coulomb drag on collective spin excitations, and developed into a much larger international project spanning over three years, which was funded in the UK by a Royal Society grant, with additional funding from the Engineering and Physical Sciences Research Council (EPSRC).

Dr D?Amico said: ?This work has developed into a strong international collaboration which has greatly improved our understanding at fundamental level of the role of many-body interactions on the behaviour of electron spins.

?By combining experimental and theoretical work, we were able to demonstrate that through many-body interactions, a macroscopic collection of spins can behave as a single entity with a single macroscopic quantum spin, making this much less susceptible to decoherence. In the future, it may be possible to use these excitations as signals to transport or elaborate information at the quantum level.?

After reporting their results in the journal Physical Review Letters last year, the team of scientists confirmed and extended the results by considering different materials and type of excitation. The second set of experiments, were recently reported in Physical Review B (Rapid Communication) and highlighted by the Journal as an ?Editor?s Suggestion?.

Dr Florent Perez, who led the experimental work with Florent Baboux, at the CNRS/Universit? Paris VI, says the results strongly suggest that the quantum nature of the macroscopic spin is universal to collective spin excitations in conductive systems.

He said: ?The collaboration with Irene D?Amico and Carsten Ullrich has been particularly powerful to disentangle the puzzle of our data. In our first joint work we constructed an interpretation of the phenomenon which was confirmed in a second investigation carried out on a different system. This paved the way for a universality of the effect.?

Lenovo ThinkPad Helix starts shipping, Seton Hall University gets early units

Lenovo ThinkPad Helix starts shipping, Seton Hall University gets early units

Lenovo's ThinkPad Helix has had one of the rockier roads to the US market, having been promised for February only to be delayed to April. Things are getting smoother, however, as the first units of the are rolling off the production line -- and there are already customers waiting at Seton Hall University. Keeping up its recent practice of handing out gadgets to junior students, the school expects to test the dockable Windows 8 tablet within a few weeks, and then deliver about 2,000 units to newcomers starting in June. The turn toward a hybrid lets the university settle on one PC design for the fall rather than divide its attention between tablets and Ultrabooks, Seton Hall's Drew Holden says. As for the general public? Lenovo hasn't officially put the Helix on sale through its own store, but a handful of customers say they've already received theirs through other channels. In any event, keep a close watch on third-party stores if you're willing to part with $1,499 for a ThinkPad convertible.
