The US Federal Emergency Management Agency (FEMA) website (for requesting disaster aid) is only functional for applicants using the latest version of the Internet Explorer web browser on the Microsoft Windows operating system. Users with other web browsers, such as Netscape, Opera, Safari, Firefox, or operating systems other than Windows, are effectively screened out of the site, which gives them a message that they need to download Internet Explorer version 6 or call FEMA at 1-800-621-3362 to register.

Relief workers are setting up many computer kiosks for evacuees to use. These kiosks are built from donated computers, many of which are unable to run Windows and/or Internet Explorer. Most of these kiosks use LiveCD versions of Linux, leaving evacuees unable to fill out aid forms.

A spokesperson for FEMA told MSNBC they were aware of the problem, and were trying to resolve the issue. They were, however, unable to provide an estimate of when the problem would be solved. Mike Quealy, a FEMA spokesperson, said the issue occurred because this tool was originally designed for in-house use by people working at the call center.

Telling the Opera web browser to spoof its user agent, by identifying itself as Internet Explorer, appears to trick the FEMA website into allowing the user to fill out the form. Firefox users can install the Prefbar extension (http://prefbar.mozdev.org/), and use the “User Agent Spoof” dropdown to achieve the same effect. Safari users can use the Debug drop-down menu (http://developer.apple.com/internet/safari/faq.html#anchor14), and use the “User Agent” option to achieve the same effect. Other options are to run Windows and Internet Explorer in an emulator such as VirtualPC on the Mac or VMware on Linux. This option is slow and requires the user to already own or purchase a license for Windows and the emulator software. Purchasing the software can cost several hundred dollars. Implementing a software compatibility layer, like the GPL wine project, allows the user to run certain Windows software on Linux, but still requires valid licenses for Windows.

On Monday, scientists from the Stanford University School of Medicine announced the invention of a new diagnostic tool that can sort cells by type: a tiny printable chip that can be manufactured using standard inkjet printers for possibly about one U.S. cent each. Lead researchers say this may bring early detection of cancer, tuberculosis, HIV and malaria to patients in low-income countries, where the survival rates for illnesses such as breast cancer can be half those of richer countries.

Existing methods tend to identify cell types using fluorescent or magnetic labels, which take time to attach, but this platform uses the phenomenon of dielectrophoresis: because different kinds of cells have different levels of receptivity to electrical fields, a trait called polarizability, when an electric potential gradient is activated around the chip, different cells are pulled in different directions at different speeds. This allows doctors to diagnose cancer by determining the number of tumor cells in a patient’s blood sample. Different chips can be printed to diagnose different diseases.

Physically, the scientists say, the system has two parts. Cells are held in a clear microfluidic chamber made of silicone. The chip itself is an electronic strip that can be printed onto flexible polyester. Most lab-on-a-chip devices must be manufactured by professional staff in specialized facilities called clean rooms and can take weeks, but the chip component of this system can be made almost anywhere in as little as twenty minutes. The chips cost approximately one U.S. cent to produce (US$0.01) and can be reused. For comparison, a standard flow cytometry machine can cost US$100,000 to purchase.

“Enabling early detection of diseases is one of the greatest opportunities we have for developing effective treatments,” said lead author and electrical engineer Dr. Rahim Esfandyarpour. “Maybe $1 in the U.S. doesn’t count that much, but somewhere in the developing world, it’s a lot of money.”

Senior author Dr. Ron Davis of the Stanford University Genome Technology Center compared this invention to that of low-cost genome sequencing, which helped lead to personalized medicine.

The findings appeared in the Proceedings of the National Academy of Sciences on Monday.

A new report, titled “Global Deserts Outlook,” has been released on World Environment Day by the United Nations Environment Programme (UNEP). The report suggests that the world’s deserts face dramatic changes as a result of global climate change: high water demands, tourism and salt contamination of irrigated soils. Desert margins and mountainous areas within deserts that have been important for people, wildlife and water supplies for millennia, are under particular threat, say UNEP.

2006 is the United Nations‘ International Year of Deserts and Desertification. Yet deserts could become the “carbon-free power houses of the 21st century,” some experts believe. They argue an area 800 by 800 km of desert, such as the Sahara, could capture the solar energy to generate all the world’s electricity needs – and more.

The report, prepared by experts from across the globe, flags options that may help governments and relevant bodies deliver a more sustainable future for the Earth’s desert regions.

“There are many popular and sometimes misplaced views of deserts which this report either confirms or overturns. Far from being barren wastelands, they emerge as biologically, economically and culturally dynamic while being increasingly subject to the impacts and pressures of the modern world,” said Shafqat Kakakhel, UNEP’s Officer in Charge and Deputy Executive Director.

“If the huge, solar-power potential of deserts can be economically harnessed the world has a future free from fossil fuels. And tourism based around desert nature can, if sensitively managed, deliver new prospects and perspectives for people in some of the poorest parts of the world,” said Mr Kakakhel.

Almost one-quarter of the earth’s land surface – some 33.7 million square kilometres – has been defined as “desert” in some sense. These deserts are inhabited by over 500 million people, significantly more than previously thought. In many parts of the world desert cores remain pristine, representing some of the planet’s “last remaining areas of total wilderness,” stated the UNEP in a news release.

Desert species are on the brink of extinction the Global Deserts Outlook reports. At risk animals include various species of Gazelle, Oryx, Addax, Arabian Tahr and the Barbary sheep as well as one of the falconers favourite prey, the Houbara. “At greatest risk are the few patches of dry woodlands associated with desert mountain habitats which may decline by up to 3.5 per cent per year,” said the study.

As a result of their valuable water supplies being diverted to domestic or agricultural use, desert wetlands, fed by the large rivers crossing deserts, are probably the most threatened ecosystem. Probable impacts include those created by roads, settlement expansion and other infrastructure developments around areas of desert montane. By 2050 the report estimates that desert wilderness – those areas where there are no nearby roads – will decline from just under 60 per cent of the current total desert area to just over 30 per cent.

The pharmaceutical potential of desert plants has yet to be tapped, suggests the report. Scientists across the globe are analysing many desert plants for potential medicinal compounds – including anti-cancer and anti-malarial substances, antioxidants, as well as appetite suppressants.

Emily Perry, a British actress has died at the age of 100.

Born on June 28, 1907 in Torquay, Devon, England, she was known for playing Madge Allsop, Dame Edna Everage‘s long-suffering, silent “bridesmaid”; she began playing the role at the age of 80.

Barry Humphries (Dame Edna) said, “It is a great loss to me, she was a close friend.”

As an actress in her own right, her filmography is limited to her appearances with Dame Edna, except for a 1995 appearance, in her late eighties, on an episode of Last of the Summer Wine as “Mrs. Broadbent”.

She appeared as herself in Night of a Thousand Faces. Prior to gaining fame, Perry spent 25 years running a dancing school for children.

Wikinews reporter Iain Macdonald has performed an interview with Dr Isabella Margara, a London-based member of the Communist Party of Greece (KKE). In the interview Margara sets out the communist response to current events in Greece as well as discussing the viability of a communist economy for the nation. She also hit back at Petros Tzomakas, a member of another Greek far-left party which criticised KKE in a previous interview.

The interview comes amid tensions in cash-strapped Greece, where the government is introducing controversial austerity measures to try to ease the nation’s debt-problem. An international rescue package has been prepared by European Union member states and the International Monetary Fund – should Greece require a bailout; protests have been held against government attempts to manage the economic situation.

A civilian known as ‘Jimmy Justice’ who resides in New York City (NYC), New York, the largest city in the United States, has been videotaping NYC police officers and city workers, breaking the law while on the job.

Since 2007, he claims to have caught “hundreds of officers and other city employees violating the law,” and says he has them all on camera. He has posted his best confrontations with them to the video sharing website YouTube. As a result, Justice states that he has been asked to do a United States television show and Wikinews got an exclusive interview with him. For protection, Justice wished not to be called by his real name in fear of police retaliation.

Last year, Justice videotaped a police officer parking in front of a fire hydrant, but has only recently gained attention on social networking news sites such as Digg and reddit.com. So Wikinews contacted Mr. Justice, known as JimmyJustice4753 on YouTube, for an exclusive interview to find out what caused him to get revenge on the law.

On June 30, 2007, Justice caught officer E. Anderson of the NYPD, traffic division, parking directly in front of a fire hydrant while she went inside a restaurant to take a 15 minute lunch break.

“Do you think there is something wrong with parking a vehicle, blocking a fire hydrant,?” says Justice while following Anderson to her car after her meal.

“Mrs. Anderson I’m talking to you,” says Justice as Anderson ignores him. “You parked your vehicle blocking a fire hydrant. You are not allowed to do that. Somebody else would get a ticket for that. Why are you allowed to do it? You should be ashamed of yourself Mrs. Anderson.”

By this time, the incident has gained the interest of people nearby the scene and passing it. One unidentified woman, who claims to be a retired NYC police officer decides to intervene stating that people “are not supposed to film any police, [or] anybody employed with the police department because of the terrorism.” A short time later the woman walked off camera.

Since 2007 Justice says he has caught “hundreds of law enforcement officers and city officials” on “over 30 hours of video” violating laws from illegal U-turns in business districts to blocking bus stops and fire hydrants. Justice has only uploaded the “most colorful ones to YouTube” and recently, on April 8, 2008, Justice videotaped a NYPD tow truck officer blocking a hydrant while he also ate lunch inside a restaurant. According to NYC law, it is illegal for any vehicle to park within 15 feet of a fire hydrant and to park in front of a bus stop. It is also illegal for any person to make a U-turn in a business district. Fines for these violations can cost a driver up to US$115.00 for each violation occurred.

When Wikinews asked Justice why he decided to start filming the violations made by officials he answered, “what bothers me is watching an officer write someone a summons and then commit the exact same violation with their official vehicle. I started making these videos to remind the officers (and complacent civilians) that City employees have to abide by the same laws that they are paid to enforce. I plan on doing this and inspiring others to do this as well as a means of leveling the playing field against discourteous officers.”

“In NYC, the traffic cops are notorious for their draconian indiscretion in handing out summonses to civilians for petty violations. Obviously the laws are not enforced as a matter of public safety, but rather to raise revenue,” added Justice.

Justice makes little effort to get the violations on videotape saying “all I have to do to catch them is open my eyes.”

“The problem with abuse of authority is rampant in New York City. I take my video camera with me on the way to work and on the way to social events and band rehearsals and when I see action it takes me less than 4 seconds to have the camera out and in record mode,” states Justice.

His videos have drawn the attention of media and he has been featured on ABC’s ‘I-caught videos’ and Inside Edition. Justice also states that the popularity of his videos have gotten the attention producers in Hollywood, California and as a result, there are plans for a television show.

Since Justice began getting even with officials and their violations, he states that there has been a positive change in the communities.

“The publicity my videos have received has effected positive change in the community, but we still have a long road ahead of us,” added Justice.

As a result of his videos, at the time the NYPD launched an investigation into the violations, but it is not known if any officers were charged or punished. Justice himself has never been arrested, but has been assaulted.

“I have never been arrested for this yet but they have threatened me with arrest. I have been spit on, cursed at, assaulted, and I had 2 cameras broken already,” added Justice.
