Rocks formed during quakes may be more abundant than previously reported

Saturday, January 31st, 2009

A new research has suggested that rocks formed only under the extreme heat and friction during earthquakes, called pseudotachylytes, may be more abundant than previously reported.

The new research, focused on eight faults found in the Sierra Nevada in the US.

Geologists have previously debated whether these rocks are rarely produced or not based on an apparent absence in the rock record, most likely brought about by the difficulty in identifying them.

Only a small fraction of the energy released in an earthquake is consumed by seismic waves. The formation of pseudotachylytes reveals the importance of the heat generated by the earthquake process.

Pseudotachylytes form by frictional melting during co-seismic faulting at significant depths in the crust. They are not easy to identify, requiring evidence that the fault rock has passed through a melt phase.

They are generated by frictional heating of the slip surface, the melting of which may account for a significant proportion of energy released during an earthquake.

Past surveys of the Sierra Nevada, which reported an absence of pseudotachylytes, have focused on the geometry and mechanics of the faults rather than the geological details of the rock types and composition.

However, the authors of this research have reported an abundance of pseudotachylytes throughout the area.

The pseudotachylytes they describe range from easily identified to impossible to identify from field data alone.

According to the researchers, further study of pseudotachylytes will ultimately reveal more about energy partitioning during earthquakes.

Swiss police google farmers, find marijuana field

Saturday, January 31st, 2009

Swiss police said Thursday they stumbled across a large marijuana plantation while using Google Earth, the search engine company’s satellite mapping software.

Police said they arrested 16 people and seized 1.1 tons (1.2 US tons) of marijuana as well as cash and valuables worth 900,000 Swiss francs ($780,000).

Officers discovered the hemp field in the northeastern canton (state) of Thurgau last year while investigating an alleged drug ring, said the head of Zurich police’s specialist narcotics unit Norbert Klossner.

The plantation, measuring almost two acres (7,500 square meters), was hidden inside a field of corn. But officers using Google Earth to locate the address of two farmers suspected of involvement in the drug operation quickly spotted the illegal crop.

“It was an interesting chance discovery,” said Klossner.

Prosecutor Gabi Alkalay told reporters in Zurich that she plans to complete her criminal investigation in February, after which she will formally charge the 16 suspects and ask for prison sentences for all of them.

The gang is alleged to have sold up to 7 tons (7.7 US tons) of hashish and marijuana between 2004 and 2008, with an annual turnover of 3-10 million francs a year, officials said.

Security nod for British firm to roll out telecom services

Friday, January 30th, 2009

The Department of Telecommunications (DoT) has given security clearance to British telecom major Cable & Wireless (C&W) to roll out voice, data and Internet services in India, a top company official said.

‘We are the first overseas telecom service provider to secure the DoT approval for launching our multi-services platform (MSP) in India’s booming telecom market,’ C&W India operations Managing Director Sunanda Das told IANS from Mumbai.

The approval includes clearance for the operator’s two international gateways each in Mumbai and Chennai under the Lawful Interception and Monitoring Solution (LIMS) norm.

It is mandatory for telecom service providers to allow law-enforcing agencies to intercept and monitor any communication through voice or data using various protocols.

‘Besides voice service for national and international calls, we will offer international private leased circuit (IPLC) directly to enterprises,’ Das noted.

Though C&W obtained a licence in February 2008 for Rs.20.5 million (Rs.2.5 crore), the security nod was given 11 months later, as the elaborate process involved testing and validation of its equipment and backbone.

‘We have invested about $30 million upfront in deploying the equipment to kick-start our services initially in New Delhi, Mumbai, Bangalore and Chennai. Another $20 million has been lined up to expand our footprint in other cities such as Hyderabad, Pune and Ahmedabad,’ Das said.

Admitting that the company was late in coming into the world’s fastest and second largest telecom market, Das said potential for data and other carrier services was immense despite a blip in the current downturn, as enterprises scout for cost-effective solutions to optimise operations and expand business worldwide.

‘Multinationals and large Indian corporates will benefit from our high-quality managed IP (internet protocol) services, Ethernet-based solutions and value-added communications applications with greater reliability, availability and performance,’ Das said.

Besides the burgeoning information technology (IT) sector, the operator is targeting the banking, financial services and insurance (BFSI), media & entertainment and manufacturing sectors as enterprise customers for its range of services on its MSP.

‘We have been providing our services to about 150 customers in the IT and BFSI verticals using the networks of state-run Mahanagar Telecom Nigam Ltd (MTNL) in Mumbai and Delhi and Bharat Sanchar Nigam Ltd (BSNL) in other cities. With our own equipment and networks, we will be able to ramp our services in terms of quality and capacity,’ Das said.

As a global supplier of Internet, data and voice solutions, C&W provides enterprises and carrier services to telecos in the US, Europe, Britain and Asia. Its customers in India will be migrated to its network from February.

At the heart of its service portfolio is the IP-based virtual private network (VPN), which provides high-speed, global IP network service connecting all sites through secure dedicated network infrastructure.

‘With core fibre backbone spanning the globe, real-time online reporting and industry-leading service level agreements (SLAs), our IP-VPN QoS is ideal for wide area network (WAN) implementation and capable of responding to the rapidly changing business environment,’ Das said.

British Telecom (BT) and AT&T are the other two leading international operators, which have been given licenses but waiting for security clearances to rollout their services in the Indian sub-continent.

A survey of 10-year-old children suggests that a 10p pencil is as good as a much expensive Nintendo brain-trainer at stimulating the memory. The study’s finding dismisses the claim in Nintendo’s advertising campaign, featuring Nicole Kidman, that users can test and rejuvenate their grey cells. “The Nintendo DS is a technological jewel. As a game it’s fine. But it is charlatanism to claim that it is a scientific test,” Times Online quoted Alain Lieury, professor of cognitive psychology at the University of Rennes, Brittany, who conducted the survey, as saying. Nintendo claims to have developed certain “edutainment” programmes-like Big Brain Academy and Brain Training-which improve “practical intelligence by improving blood flow to the brain. The company claims that its programmes can make users “two to three times better in tests of memory.” It even claims to assess capacity by measuring “brain age”, and insists that older people can keep their minds young by using the console. “The more you use the brain in a challenging way, the better it can work. We know that the mental processes of our brain start to weaken if we only use it in our routine daily life,” the Japanese neuroscientist Ryuta Kawashima, who developed Brain Training, says on the Nintendo website. Professor Lieury said that helping children with their homework, reading, playing Scrabble or Su Doku or watching documentaries, rather than soap operas, matched or beat the console. The researchers conducted an study on 67 ten-year-olds with a view to testing whether Nintendo’s claims were true. “That’s the age where you have the best chance of improvement. If it doesn’t work on children, it won’t work on adults,” Professor Lieury said. The researchers divided the children into four groups-the first two did a seven-week memory course on a Nintendo DS, the third did puzzles with pencils and paper, and the fourth just went to school as normal. Before and after the programmes, the children undertook a variety of tasks-logic tests, memorising words on a map, doing sums and interpreting symbols. The researchers said that the children who used the Nintendo DS system failed to show any significant improvement in memory tests. They agreed that the children using the Nintendo DS did do 19 per cent better in mathematics, but so did the pencil-and-paper group, while the fourth group did 18 per cent better. The researchers also observed that the pencil-and-paper group recorded a 33 per cent improvement in memorising, while the Nintendo children were 17 per cent worse. In logic tests the Nintendo children registered a 10 per cent improvement, as did the pencil-and-paper group. According to the researchers, the children who had no specific training improved 20 per cent. In a book titled Stimulate Your Neurones, due out this month, Professor Lieury says: “There were few positive effects and they were weak. Dr Kawashima is one of a long list of dream merchants.”

Wednesday, January 28th, 2009

A British computer expert accused by the United States of the “biggest military hack of all time” won the right on Friday to launch a new legal challenge against plans to extradite him.

Gary McKinnon was arrested in 2002 after U.S. prosecutors charged him with illegally accessing computers, including the Pentagon, U.S. army, navy and NASA systems, and causing $700,000 worth of damage.

He has been fighting attempts to extradite him ever since a British court ruled in 2006 that he should be sent to the United States for trial.

In the latest round of his legal battle, two judges at London’s High Court ruled that he could seek a judicial review of Home Secretary (interior minister) Jacqui Smith’s decision to approve the extradition, the Press Association news agency reported.

Lawyers for McKinnon, who has been diagnosed with Asperger’s Syndrome, argued his health would suffer and he would be at real risk of suicide if he was handed over to U.S. authorities.

“It is the right decision,” his lawyer Karen Todner said. “This case has been going on since 2002 and finally we have got the first right decision.”

McKinnon is accused of causing the entire U.S. Army’s Military District of Washington network of more than 2,000 computers to be shut down for 24 hours.

At the time of his indictment, Paul McNulty, U.S. Attorney for the Eastern District of Virginia, said: “Mr McKinnon is charged with the biggest military computer hack of all time.”

He could face up to 70 years in prison if convicted by a U.S. court.

McKinnon told Reuters in 2006 he was just a computer nerd who wanted to find out whether aliens really existed and became obsessed with trawling large military networks for proof.

He had used his own computer with a 56K dial-up modem at his London home with no password protection.

Britain’s new Director of Public Prosecutions (DPP) Keir Starmer is considering a request from McKinnon for him to be prosecuted in Britain where his legal team believe he would receive a much shorter sentence.

He has signed a statement accepting that his hacking constituted an offence under Britain’s Computer Misuse Act and the High Court was told Smith had agreed not to extradite him until the DPP’s decision, due in the next four weeks.

‘Shoe phone’ may soon be a reality

Monday, January 26th, 2009

A Flinders University computer scientist is trying to make the shoe phone a reality.

Post-doctoral fellow in bioinformatics, Paul Gardner-Stephen, who first developed a ‘phone inside a shoe’ as an amateur theatre prop, insists that there are practical and technological advantages of the device, reports News.com.au.

“Relaying voice communications via a shoe is technologically similar to relaying medical data for remote patient monitoring, such as pulse, blood pressure, blood oxygenation and so forth,” Dr Gardner-Stephen said.

“And a shoe is a good location for housing the electronics required for storing and communicating these measurements.

“Secondly, because our feet, and therefore our shoes, conduct large forces as we stand and walk, energy can be harvested to charge the device during ordinary activity.

“A shoe-based device would not only be easy to wear, it could run significantly longer between battery charges,” the expert added.

According to the scientist, there was potential to develop the telephone function for use in home nursing and aged care facilities.

The shoe-based platform made it possible for the device to detect shocks and orientation changes resulting from a fall and then call for help, the expert said.

Bush leaves behind a mixed technology legacy

Monday, January 19th, 2009

news analysis Months after being sworn in as president, George W. Bush sat down with reporters and his wife, Laura, for a technology-themed event: a relaunch of the Whitehouse.gov Web site, which previously had been rather dilapidated.

Bush and his aides proudly demonstrated the new features, including photo essays, better access for the disabled, and a kids’ area with details about the First Pets. The president said the Web site would let Washington become “more accessible” and let Americans “participate in the process.”

Less than two weeks later, the World Trade Center and Pentagon were attacked, the White House shifted to a wartime footing, and Bush never looked back. Instead of a presidency that might have become known for its technology policies–Bush was, remember, a businessman in Texas–he leaves Washington this week amid controversies involving the Iraq war, torture, wiretapping, an economic crisis and bailouts, and a doubled federal debt.

The 43rd president leaves behind a technology legacy characterized less by intent than by casual neglect. Bush and (especially) Vice President Dick Cheney and Attorney General Alberto Gonzales were adamant in their defense of warrantless wiretapping, and made it a priority of their administration. “The president has the inherent authority under the Constitution, as commander-in-chief, to engage in this kind of activity,” Gonzales said in 2005 after details became public.

Yet wiretapping and its cousins such as monitoring financial transactions were the exception, not the rule. On more routine, humdrum topics, the White House seemed happy to defer to Congress or to its appointees in various federal agencies, rather than use the authority of the president to focus attention in certain tech topics–something President Bill Clinton regularly did to applause from Silicon Valley firms, whose executives would rarely turn town an invitation to the White House.

That apparent neglect occasionally led to embarrassing results, such as the Bush administration acknowledging last month that it opposed a spectrum plan backed by Kevin Martin, Bush’s own appointee who heads the Federal Communications Commission. Bush’s Federal Trade Commission warned that Net neutrality regulations would be dangerous, as did the Justice Department; but the FCC went ahead anyway and now is trying to defend its actions in court.

For his part, Bush has stressed that September 11, 2001, was what changed his priorities and his views.

“This evening, my thoughts return to the first night I addressed you from this house–September the 11, 2001,” Bush said in his farewell address to the nation last week. “As the years passed, most Americans were able to return to life much as it had been before 9/11. But I never did.”

(It may be a little too facile to attribute a near-complete policy shift to that date. There is some evidence that the National Security Agency’s wiretapping program began immediately after Bush took office in 2001; a lawsuit filed by Qwest Communications’ former chief executive says that he was approached by the NSA at that time, and another lawsuit makes similar allegations involving AT&T.)

The administration’s broad claims of expansive executive power and an Iraq occupation that’s lasted longer than World War II–coupled with massive deficits and a ballooning federal bureaucracy–eventually estranged some Silicon Valley Republicans who once were Bush loyalists. Venture capitalist Tim Draper chaired three Bush fundraisers circa 2000; last year he gave the legal maximum to President-elect Barack Obama.

“It’s good to have a fresh face,” Draper said in a recent interview. “At least from the press, we’ve seen about six years of fear. I’d like to see six years of opportunity and what that could do for our country, and I think that might happen with Obama.”

What could, perhaps, have been a Reaganesque technology agenda founded on free market principles with an emphasis on free trade and immigration reform shifted focus to security and surveillance, especially with the creation of the U.S. Department of Homeland Security in November 2002.

“The Bush administration was largely AWOL on technology policy,” said Ed Black, president and CEO of the Computer and Communications Industry Association, a technology trade association that supports antitrust regulation and counts Oracle, RedHat, and Sun Microsystems as members. “It was always an afterthought.”

The Bush White House got off to a strong start by revamping Whitehouse.gov and launching the President’s Council of Advisors on Science and Technology in 2001.

Yet even with the new White House Council, the lack of technology expertise within the administration was apparent from the beginning, said Black, who is listed as giving money to Hillary Clinton, Bill Richardson, and the Democratic Congressional Campaign Committee, but no Republicans.

“There were only a handful of people who by and large were the administration’s technology people,” he said. “In some cases, while they were fine people, they lacked the clout to make a big difference.”

In many ways, a laissez-faire approach On the other hand, the Bush administration’s relatively laissez-faire approach when it came to Internet regulation turned out to be good for business. Bush opposed Internet taxes, though he spent little political capital on the topic. He expended more when supporting immigration reform, even when it put him at odds with conservative members of his own political party.

“Generally, the technology industry has flourished under the Bush administration,” said Gary Shapiro, president of the Consumer Electronics Association, the organization that stages the annual Consumer Electronics Show. “It’s a legacy of those who came before as well that the U.S. has managed to attract virtually every major company based around the Internet. All of these companies have been in the United States because of U.S. policy and creativity.”

One early flashpoint came after a federal appeals court in Washington, D.C., ruled that U.S. District Judge Thomas Penfield Jackson’s attempt to break up Microsoft could not stand. Jackson had, in violation of judicial ethics rules, invited favored reporters into his chambers for private chats about the perfidy of Microsoft executives–typically likening them to gangland killers and stubborn mules who should be walloped with a 2-by-4.

The appeals court’s ruling overruled Jackson, tossed out his breakup order, and concluded that Microsoft had not illegally “tied” the browser or tried to monopolize the browser market to the detriment of Netscape Navigator. That left the new Bush administration with less antitrust ammunition, and it settled the case a few months later.

Liberal critics of the administration, however, blamed the settlement on a political philosophy hostile to expansive antitrust claims. They found even more to complain in a series of FCC-approved telecommunications mergers that took place during the Bush administration, including the merger between AT&T and BellSouth, Verizon and MCI, and SBC Communications and AT&T. (For its part, the White House characterizes itself as having “pro-growth telecommunications policies.”)

The free market principles of the Bush administration were extended globally, and “the focus on free trade has been the most principled and lasting legacy” of the Bush administration, Shapiro said.

Bush can claim as victories the Central American Free Trade Agreement and a trade deal with Peru. He managed to ink deals with Colombia and South Korea, but Congress did not ratify them. Although there was more emphasis on bilateral agreements than multilateral trade deals, Bush’s push for free trade was significant for an industry that is thoroughly international, Shapiro said, and especially laudable given the growing anti-trade sentiment in the country, particularly in Democratic and union circles.

Stronger protections for intellectual property were put in place with the Prioritizing Resources and Organization for Intellectual Property Act. Copyright law tends to be relatively bipartisan: there’s no reason to believe that a Democratic administration would have been any different. President Clinton signed the Digital Millennium Copyright Act (which was overwhelmingly approved by a bipartisan congressional majority) into law, and Obama has chosen the recording industry’s favorite lawyer for a senior administration position.

“There’s a gradual increasing respect in the developing world for IP, and I suspect that’s a trend that will continue,” Shapiro said.

Immigration policy in the Bush years, however, is largely seen as a disappointment from the tech perspective.

National security concerns and a loss of focus on visas was disappointing for us,” Shapiro said. “In terms of attracting the best people around the world, we know we’re losing people to countries with less rigorous security processes.”

While it was negotiating international agreements, the Bush administration could have done more to create an Internet climate optimal for Internet companies by supporting policies and legislation such as the Global Online Freedom Act, Black said.

“Increasingly, we’ve seen country after country use the power of the government to block sites and to make companies liable for doing those things,” Black said. “The Internet was created by the U.S., and for the U.S. not to have been a forceful advocate of U.S. principals of openness was squandering an opportunity.”

The administration’s silence on the issue may have been influenced by its defense of warrantless wiretapping, which may have caused it to be reticent on this topic.

“We didn’t do any work on (privacy policy) in the last eight years, and the work we did do nobody wants to keep, like the warrantless surveillance program,” said James Lewis, a director and senior fellow at the hawkish Center for Strategic and International Studies. “9-11 knocked the privacy balance askew. There were things we needed to do (to ensure national security), but we never tackled them in a way that doesn’t weaken privacy.”

While the Bush team was collecting information on its own, it did little to stop the private sector from its own questionable data collection, said Jeff Chester of the Center for Digital Democracy, a liberal group that advocates more federal regulation.

The Federal Trade Commission essentially ignored “the greatest threat to privacy we’ve ever experienced,” he said.

The ramifications of commercial data collection is evident in the financial meltdown of the past year, Chester said, given that many people fell prey to online targeting of questionable financial services.

On the other hand, the Justice Department did mount an aggressive challenge to Google’s planned advertising deal with Yahoo, even going so far as to hire a well-known litigator for the job. Google walked away from the deal in November, citing antitrust concerns.

Cybersecurity Homeland Security was supposed to mastermind the government’s cybersecurity efforts, combining what had previously been the FBI’s National Infrastructure Protection Center, the Defense Department’s National Communications System, the Commerce Department’s Critical Infrastructure Assurance Office, an Energy Department analysis center and the Federal Computer Incident Response Center. But six years later, the agency proved to be anything but efficient at that task, prompting calls to move the responsibility to the White House or the National Security Agency.

Homeland Security managed to pour $400 million into cybersecurity without coming up with a coherent “cybercrisis” plan. And in 2004, the Homeland Security Department was given a discretionary reserve fund of $5.6 billion for Project BioShield, part of the president’s war on terror.

“You had this idea you could apply the tech-heavy solutions we used on the DOD side to fix what were seen on problems on the homeland security side,” said Lewis, who chaired CSIS’s Commission on Cybersecurity for the 44th Presidency. “The tendency in the U.S. is to spend a lot to reduce risk. We’ve been doing that since the 1950s, so this might have been the reaction (to September 11, 2001) no matter who was in office.”

The tech industry can be grateful for one important Bush administration decision. It never resumed the legal assault on encryption software, including PGP and Web browsers, which the Clinton administration had escalated in the 1990s. Even after the September 11, 2001, attacks, when some Republican senators and think tanks were calling for domestic restrictions on encryption without backdoors for government surveillance, the White House never followed suit.

The White House points out that President Bush signed into law the largest federal R&D budget in history and funded programs like the $1.9 billion Networking and Information Technology Research and Development initiative.

Kei Koizumi, director of the R&D budget and policy program for the American Association for the Advancement of Science, noted that the Bush administration’s support for R&D was strong in the first term but cut back substantially in the second term because of overall budget deficits. Large investments in war and a stated desire to cut domestic federal spending drained fund that could have gone to support the American Competitiveness Initiative, which was created to strengthen math, science, and foreign language education in the U.S.

“When you talk about a Bush legacy for science funding you have to talk about legacy for the federal budget,” Koizumi said, “and by most accounts that’s not great because of debt.”

Bush’s vision for NASA to carry out human exploration of the moon and Mars has also created a quandary for the agency, which lacks the funding for all of its goals.

“The unwritten legacy is NASA will have to squeeze, juggle, and cut its portfolio to keep doing nonhuman exploration, climate research, and work on the space shuttle,” Koizumi said.

25 most dangerous software coding errors that help cyber criminals revealed

Friday, January 16th, 2009

The US National Security Agency along with 30 organisations have put together a list of the 25 most dangerous coding mistakes in the world.

The list contains errors, which may disclose a number of security holes or vulnerable areas that can be targeted by cyber criminals.

According to experts, many of these errors are not well understood by programmers.

The SANS Institute in Maryland said that in 2008, just two of the errors led to more than 1.5m web site security breaches.

This is believed to be the first time the industry has reached agreement on the worst things that can creep into software while it is being written.

The organisations, which helped making the list, include the US National Security Agency, the Department of Homeland Security, Microsoft, and Symantec published the document.

“The top 25 list gives developers a minimum set of coding errors that must be eradicated before software is used by customers,” the BBC quoted Chris Wysopal, chief technology officer with Veracode, as saying.

SANS director, Mason Brown said: “There appears to be broad agreement on the programming errors. Now it is time to fix them. We need to make sure every programmer knows how to write code that is free of the top 25 errors.”

While, most of the earlier advice focused on vulnerabilities that could have originated from programming errors, the 25 list examines the actual programming errors themselves.

The 25 Most Dangerous Programming Errors are:

CWE-20:Improper Input Validation

CWE-116:Improper Encoding or Escaping of Output

CWE-89:Failure to Preserve SQL Query Structure

CWE-79:Failure to Preserve Web Page Structure

CWE-78:Failure to Preserve OS Command Structure

CWE-319:Cleartext Transmission of Sensitive Information

CWE-352:Cross-Site Request Forgery

CWE-362:Race Condition

CWE-209:Error Message Information Leak

CWE-119:Failure to Constrain Operations within the Bounds of a Memory Buffer

CWE-642:External Control of Critical State Data

CWE-73:External Control of File Name or Path

CWE-426:Untrusted Search Path

CWE-94:Failure to Control Generation of Code

CWE-494:Download of Code Without Integrity Check

CWE-404:Improper Resource Shutdown or Release

CWE-665:Improper Initialization

CWE-682:Incorrect Calculation

CWE-285:Improper Access Control

CWE-327:Use of a Broken or Risky Cryptographic Algorithm

CWE-259:Hard-Coded Password

CWE-732:Insecure Permission Assignment for Critical Resource

CWE-330:Use of Insufficiently Random Values

CWE-250:Execution with Unnecessary Privileges

CWE-602:Client-Side Enforcement of Server-Side Security

Handling a Personal Injury case

Friday, January 16th, 2009

If you are the victim of a car accident, then you should start thinking about the legal steps you will need to take. You are going to need money to repair your vehicle and heal any injuries from the wreck. If you want to protect your rights, then you need to have an Arizona personal injury attorney. They will be able to handle the legal aspects while you focus on healing.

You also need to hire one as quickly as you can. The insurance companies don’t usually wait. They are usually right on the case with paperwork that limits their liability. Don’t sign anything until you get a lawyer to look at the paperwork. It’s really that simple. There are other precautions though. You shouldn’t discuss the case with any representatives or agree to be recorded. These can be attempts to trap you and limit their liability too. Just be polite and refer them to your attorney. They’ll know what to do. With any luck, you should be able to get your case settled out of court for a fair amount. In a few cases, you will have to go to court though. In this event, you’ll be even happier that you already have a good attorney on your side.

If you want to get your just compensation, then you need legal aid. Don’t hesitate to hire one of the many Arizona personal injury attorneys who have experience you need.

Dangerous drug combos pose risk for elderly

Wednesday, January 14th, 2009

Older adults in the United States are popping prescription pills, over-the-counter drugs and dietary supplements in record numbers and in combinations that could be deadly, US researchers said on Tuesday.They said more than half of US adults aged 57 to 85 are using five or more prescription or non-prescription drugs, and one in 25 are taking them in combinations that could cause dangerous drug interactions.

“Older adults in the United States use medicine and they use a lot of it,” said Dr Stacy Tessler Lindau of the University of Chicago Medical Center in Illinois, whose study appears in the Journal of the American Medical Association.

“While medications are often beneficial, they are not always safe,” she said in a telephone interview.

She noted a recent report that estimated US adults over 65 make up more than 175,000 emergency department visits a year for adverse drug reactions, and commonly prescribed drugs accounted for a third of these visits.

For the study, Lindau teamed up with Dima Qato, a pharmacist and researcher at the University of Chicago. They used data from a national survey of adults aged 57 to 85 and interviews with nearly 3,000 people in their homes to get a read on the medications they used on a regular basis.

They analyzed potential interactions among the top 20 prescription and over-the-counter drugs and the top 20 dietary supplements, and found that 68 per cent of adults surveyed who took prescription drugs also used over-the-counter drugs or dietary supplements.Men in the 75 to 85-year-old age group were at the highest risk, they said. “One in 10 men between the ages of 75 to 85 were at risk for a drug-to-drug interaction,” Qato said in a telephone interview.

BLEEDING RISKS

Nearly half of the potential drug-to-drug interactions could cause bleeding problems. The blood thinner warfarin, often sold by Bristol-Myers Squibb Co under the brand name Coumadin, was most commonly cited in potentially dangerous combinations.

Some 2 million Americans take warfarin after a heart attack, stroke or major surgery. The team found warfarin was commonly teamed up with aspirin, a drug often taken to prevent heart attacks that also interferes with clotting.

Warfarin and the cholesterol-lowering statin drug simvastatin, which is sold by Merck & Co under the brand name Zocor, was another combination that could cause potential bleeding risks.

Among non-prescription drugs, they found many people were taking the popular nutritional supplement Ginkgo biloba in combination with aspirin, another potential cause of bleeding.The team was reassured that they found no instances of people taking absolutely forbidden drug combinations, but the finding of widespread use of drugs that could cause major drug reactions was worrisome.”We think the patient needs to know about these risks,” Qato said.

The researchers recommend patients carry a list in a wallet or purse of all of the drugs and supplements they take.

And they said doctors, pharmacists and other health professionals should remember to ask about all of the medications their patients are taking.

The top 11 most anticipated games of 2009

Tuesday, January 13th, 2009

‘Punch-Out’, ‘Grand Theft Auto IV’, ‘The Beatles Game’ and ‘StarCraft II’-these are some of the eleven games that are expected to keep players hooked on to them in 2009.

Game|Life contributors Nate Ralph, Earnest Cavalli, Chris Baker and Chris Kohler, have made the list of 11 games that should make waves this year, reports Wired News.

The 11 most anticipated games of 2009 are:

Punch-Out!! (Wii)

This revival of Nintendo’s classic puzzle-sports-rhythmic-punching game will show the croissants fly from Glass Joe as he’s knocked to the canvas. It is expected to be as addictive as its previous version.

Infamous

Infamous (PlayStation 3)

Infamous is being billed as the ultimate superhero simulator, a game that lets you choose your path, saving the city or wreaking destruction.

Thelost12

Grand Theft Auto IV: The Lost and the Damned (Xbox 360)

The new Xbox 360 downloadable expansion to GTA IV offers a lengthy new narrative, and upgrades the favourite virtual metropolis with new weapons, missions, vehicles and multiplayer modes.

Resi_evil_5

Resident Evil 5 (PlayStation 3, Xbox 360)

Metal Gear Solid 4-level visual polish, a nicely modified strain of the Resident Evil 4 control scheme, online co-operative multiplayer and the woefully underrepresented setting of the African Savannah all indicate that Resident Evil 5 almost has to be something special.

Beatles660

The Beatles Game (Multiplatform)

Harmonix’s collaboration with The Beatles is the odds-on favourite to be the biggest thing to happen to videogames, and maybe even music, in 2009. Harmonix is letting go of Rock Band 3 this year to concentrate its efforts on re-creating the Fab Four’s music in interactive form. Even if this were just downloadable content for Rock Band, it would be one of the best things to happen this year.

Dawnwar1

Warhammer 40,000: Dawn of War II (Windows)

Relic Entertainment is bringing players back to the basics with Dawn of War II - namely, control of small, elite squads embroiled in close-quarters combat, with a number of traditional RPG mechanics rolled in. Dawn of War’s gleefully excessive brutality and visual flair have been revamped, adding tantalizing levels of detail to the act of vigorously throttling enemy units before hurling them through the air like a large, wet sack.

BioShock 2: Sea of Dreams (Xbox 360, PlayStation 3, PC)

According to game makers, 2K, BioShock can be its Star Wars, implying that this episode could be as awesome as The Empire Strikes Back.
