Researchers wrangle microscopic particles with sonic lasso

Researchers wrangle microscopic particles with sonic lasso

When you think about it, scientists and cowboys have a lot in common. Both are frontiersmen of a sort, both wear clothes that make them easy to identify and now they both count lassos among their essential tools. Researchers at the University of Bristol and the University of Dundee have wrangled small particles and cells by using a sonic (or ultrasonic) vortex. The whirl of sound waves allowed the teams to catch, move and orient microscopic particles, all without actually contacting them physically, which makes the solution ideal for handling delicate material. Professor Bruce Drinkwater from Bristol even suggested it could one day be used to assemble human tissue (custom assembled livers, anyone?). The sonic lasso is quite a bit more complex and less portable than its rope-based cousin, involving a circular device with 16 sources of acoustic waves. If you're looking for more technical details you'll find a link to the recently published paper titled, Dexterous manipulation of microparticles using Bessel-function acoustic pressure fields at the source.

Samsung partners with Best Buy to bring Experience Shops to 1,400 stores

Samsung partners with Best Buy to bring Experience Shops to 1,400 stores

Not content with a gazillion Galaxy phone sales, Samsung is hoping to continue winning the smartphone war in one of the biggest battlegrounds any manufacturer can face: retail. The Korean OEM has partnered with Best Buy to bring its Experience Shops to the big box retailer nationwide -- 1,400 of them by early summer (with 900 launching this month), to be precise. So what does Sammy hope to achieve? In addition to the standard shopping setup, the company wants to give customers the ability to actually use its products and get a first-hand feel of what they have to offer: phones, accessories, Smart TVs and tablets will be on display. Each shop will be manned by Samsung-employed consultants as well as specially trained Best Buy employees. This appears to be Samsung's way of offering a thorough retail experience without actually launching its very own stores across the country. It'll be interesting to see if it will be a more effective retail alternative to what companies like Apple and Microsoft have adopted, but Samsung sure seems quite optimistic about its chances. Find the press release below for the full experience.

Budget cuts border security, immigrant detention

PHOENIX (AP) ? Marco Antonio Durazo had been awaiting deportation from an Arizona detention center for six months when an officer came to get him from his cell.

"Obama doesn't have any money," the officer said.

"We found it very funny," Durazo said, but it wasn't a joke.

Soon, he was free along with hundreds of other illegal immigrants who were released by the Obama administration because of budget pressures. Officials have also scaled back border agent hours, drug patrols and staffing at border crossings ? all during the peak illegal border-crossing season.

While prompted by the nation's money woes, the changes also come amid the nation's shifting immigration policy after years of mass arrests and deportations and billions spent on border security.

The long-term impact of that change has yet to be seen. The Border Patrol said January and February numbers showed a nearly 10 percent increase in apprehensions along the Mexico border for the first two months of the year, compared with 2012.

There could be several factors for the rise, including immigrants motivated by an improving U.S. economy or those anticipating congressional action that could create a path to citizenship. The cuts come as lawmakers are struggling to work out a comprehensive immigration reform package whose success may ultimately be tied to questions of border security.

On Wednesday, Sen. John McCain led a bipartisan group of senators on a tour of the border, and they said they were close to a deal but continued to tie it to keeping immigration in check. They promised more details next week, but McCain said that there's "no doubt" in his mind that the border is less secure because of the budget cuts.

The release of more than 2,200 immigrants like Durazo drew headlines this month as the government prepared for looming cuts that began in March. In February, the government let go of hundreds of immigrants from detention centers in states including Arizona, California, Florida, Georgia and Texas. The administration planned to let roughly 3,000 more go in March, according to an internal government budget document reviewed by the AP and later released by the House Judiciary Committee.

The moves were an attempt by Immigration and Customs Enforcement to get its detainee population in line with what it could afford. The released immigrants still face deportation but will not be held while awaiting their court dates.

Some in Congress said ICE should have explained beforehand that there wasn't enough money to keep everyone in detention.

The immigrants and their lawyers say they were released with little notice or instruction beyond being told to check in periodically.

In many cases, the immigrants were dropped off in the middle of the night at bus stations or airports in metropolitan centers without money to finish their journey home. In Florida, some were released from a facility bordering rural swamp land outside Miami.

Critics argue the plan allowed the release of thousands of criminals without regard to public safety, but officials say almost all the detainees were characterized as low risk. ICE Director John Morton told a congressional panel that 10 of the 2,228 people were the highest level of offender.

"In reducing detention levels, we took careful steps to ensure that national security and public safety were not compromised," he told a congressional hearing.

Meanwhile, the Obama administration, in the midst of trying to get immigration overhauled, switched from daily declarations that the border was secure to warning of the increasingly dire consequences of cutting $754 million from Customs and Border Protection's $12 billion budget.

In the first week of the cuts, some agents in South Texas reported a spike in arrests of immigrants who said smugglers told them they would be briefly detained and then released. The agents' union quickly spread word of a "tidal wave" of immigrants taking advantage of the situation.

Several immigrants interviewed at a migrant shelter in Reynosa, Mexico, across the border from McAllen, Texas, said they had not heard anything suggesting now was a particularly good time to cross. Instead, several said they were returning home because the drug cartel that controlled river crossings made it too expensive and dangerous.

"Here, they say you can't cross the river right now because there are a lot of kidnappings. They're killing a lot of people," said Josue Manuel Vazquez, who added that he escaped kidnappers who held him for five days as they tried to extort $4,500 from his daughter, a legal U.S. resident.

Some contend the budget cuts are relatively small when put in the broader context of the huge build-up of border security over the past decade.

According to the Government Accountability Office, the Department of Homeland Security assigned about 28,100 people in 2004 to patrol land borders and inspect travelers at all ports of entry at a cost of about $5.9 billion. By the end of 2011, those figures were 41,400 employees at a cost of $11.8 billion.

"The scale of (automatic budget cuts) is minuscule compared to the vast build-up," said Geoff Boyce, spokesman for No More Deaths, an immigration advocacy group in Tucson, Ariz.

The effects of the cuts are being seen in border cities and among agents. Customs and Border Protection reduced overtime for its officers at ports of entry. In San Diego and other crossing points, that translated to fewer lanes open at land crossings and longer waits for people and trucks carrying produce and other goods from Mexico.

Those waits are only expected to worsen in coming weeks as the agency begins furloughs amid a hiring freeze. In a letter to Texas Gov. Rick Perry, Homeland Security Secretary Janet Napolitano warned that peak wait times at the busiest border crossings could reach five hours or more.

Border Patrol agents received notices advising them they would face up to 14 days of furloughs during the next six months and would no longer be eligible for overtime that for years has added an average of two hours to every agent's shift.

The agency is also suspending assignments known as "details" that sent agents from slower parts of the border to busier areas for months at a time. Agents on detail are often put up in hotels and receive a per diem.

The cuts have also forced the government to pull back on flight and ship patrols in the drug war in Central America.

Durazo learned about the budget issues while watching the news at his sister's home in the Phoenix area after his release. He crossed into the U.S. from his native Mexico in 1969 when he was 19, and he said he doesn't know what will happen next with his immigration case. He has, however, decided to embrace his good fortune.

"We gave many thanks to God, because we prayed a lot while we were in there," he said.

Link between faster 'biological' aging and risk of developing age-related diseases

Mar. 27, 2013 ? An international team of scientists led by the University of Leicester has found new evidence that links faster 'biological' ageing to the risk of developing several age-related diseases -- including heart disease, multiple sclerosis and various cancers.

The study involved scientists in 14 centres across 8 countries, working as part of the ENGAGE Consortium (list of research teams is give below). The research is published online today (27th March) in the journal Nature Genetics.

The project studied a feature of chromosomes called telomeres. Telomeres sit on the end of our chromosomes -- the strands of DNA stored in the nucleus of cells. The telomeres shorten each time a cell divides to make new cells, until they reach a critical short length and the cells enter an inactive state and then die. Therefore telomeres shorten as an individual gets older. But, individuals are born with different telomere lengths and the rate at which they subsequently shorten can also vary. The speed with which telomeres wear down is a measure of 'biological ageing'.

Professor Nilesh Samani, British Heart Foundation Professor of Cardiology at the University of Leicester and Director of the National Institute for Health Research (NIHR) Leicester Cardiovascular Biomedical Research Unit, who led the project said: "Although heart disease and cancers are more common as one gets older, not everyone gets them -- and some people get them at an earlier age. It has been suspected that the occurrence of these diseases may in part be related to some people "biologically" ageing more quickly than others."

The research team measured telomere lengths in over 48,000 individuals and looked at their DNA and identified seven genetic variants that were associated with telomere length. They then asked the question whether these genetic variants also affected risk of various diseases. As DNA cannot be changed by lifestyle or environmental factors, an association of these genetic variants which affect telomere length with a disease also would suggest a causal link between telomere length and that disease.

The scientists found that the variants were indeed linked to risk of several types of cancers including colorectal cancer as well as diseases like multiple sclerosis and celiac disease. Most interestingly, the authors found that in aggregate the seven variants also associated with risk of coronary artery disease which can lead to heart attacks.

Professor Samani added: "These are really exciting findings. We had previous evidence that shorter telomere lengths are associated with increased risk of coronary artery disease but were not sure whether this association was causal or not. This research strongly suggests that biological ageing plays an important role in causing coronary artery disease, the commonest cause of death in the world. This provides a novel way of looking at the disease and at least partly explains why some patients develop it early and others don't develop it at all even if they carry other risk factors."

Dr Veryan Codd, Senior Research Associate at the University of Leicester who co-ordinated the study and carried out the majority of the telomere length measurements said: "The findings open of the possibility that manipulating telomere length could have health benefits. While there is a long way to go before any clinical application, there are data in experimental models where lengthening telomere length has been shown to retard and in some situations reverse age-related changes in several organs."
