Doctors warn of 'aggressive' new sexually-transmitted superbug

Doctors are warning of a new sexually-transmitted superbug that they say could ultimately prove more deadly than AIDS.

The antibiotic-resistant strain of gonorrhea HO41 was reportedly discovered in Japan two years ago in a 31-year-old female sex worker.

"This might be a lot worse than AIDS in the short run because the bacteria is more aggressive and will affect more people quickly," Alan Christianson, a doctor of naturopathic medicine, recently told CNBC. "Getting gonorrhea from this strain might put someone into septic shock and death in a matter of days. This is very dangerous."

Reportedly added William Smith, executive director of the National Coalition of STD Directors: "It's an emergency situation. As time moves on, it's getting more hazardous."

According to CNBC, Smith urged Congressional lawmakers as late as last week to allocate additional funding - $54 million - to develop an antibiotic capable of fighting HO41, as well as to conduct a public awareness campaign.

"I'm hopeful we'll get the additional funds, but I can't say for sure," Smith reportedly said. "What I do know is we don't have the resources to fight this as it stands now."

"People need to practice safe sex, like always," Christianson told CNBC. "Anyone beginning a new relationship should get tested along with their partner. The way gonorrhea works, not everyone knows they have it. And with this new strain it's even more important than ever to find out. "

Cookie Monster stands accused of shoving a 2-year-old. Super Mario was charged with groping a woman. And Elmo was booked for berating tourists with anti-Semitic slurs.

Times Square is crawling with entrepreneurs who dress up as pop-culture characters and try to make a few bucks posing for photos with visitors to the big city. But some of these characters are unlike anything you've seen on "Sesame Street" or at Disney World.

They smoke, they use foul language, and they can be aggressive. At least three of them have been arrested in the past seven months.

"He was using words that were really bad," said Parmita Kurada of Stamford, Conn., who told police she got into a dispute this week with a man in a Cookie Monster costume who demanded $2 for posing with her 2-year-old son, Samay.

Kurada said that when she told the Cookie Monster that her husband needed to get cash, the shaggy blue creature pushed the boy and began calling her and the child obscene names.

"It was very scary for us, and I was crying. I didn't want to provoke him, so I said, `We'll give you the money, but stop yelling!"' she said.

Osvaldo Quiroz-Lopez, 33, was charged with assault, child endangerment and aggressive begging. His lawyer did not immediately return a call for comment.

Asked by a WNBC-TV reporter why he no longer likes the character he sees on "Sesame Street," little Samay said: "Because Cookie Monster give me boo-boo."

In the wake of the latest arrest, the bustling "Crossroads of the World" was filled Tuesday with performers, including multiple versions of Mickey and Minnie Mouse, Hello Kitty, a Transformer robot, Lady Liberty,  Super Mario and Elmo.

Many of them are immigrants trying to eke out a living in what appear to be knockoff costumes.

As street performers protected by the First Amendment, they are free to roam Times Square and work for tips that average between $2 and $5 a photo as long as they don't block traffic, sell merchandise or demand payment, police say. That's a ticketable offense that can cost about $60.

"I don't think they should charge, but if they're unemployed or homeless, and this is the only way they can make money, it's OK," said Lauren Larcara of Oakland, N.J., who posed with a torch-carrying Statue of Liberty.

Laura Vanegas, a 45-year-old native of Ecuador, changes into her Liberty robes and applies copper-green face paint behind the Times Square military recruiting station. She said she picks up $30 to $50 on her eight-hour shift.

Steve Crass, dressed as a robot in fluorescent red and white plastic panels, said he has made as much as $280 during his six-hour stint in front of Toys R Us. He acknowledged: "Some of the characters are a little too aggressive."

Police spokesman Paul Browne said in an email that the department has had "occasional issues with the `faux paws' in Times Square, but they're nominal."

The case against the Super Mario charged with groping is still pending. The Elmo accused of an anti-Semitic rant pleaded guilty in September to disorderly conduct and was sentenced to two days of community service.

City Council Speaker Christine Quinn called the Cookie Monster case "just horrible" and said lawmakers have been looking into how to regulate the characters. But she noted the issue is, well, fuzzy.

"It's very challenging legally because dressing up in a costume and walking around Times Square is, we believe, a First Amendment-protected activity," said Quinn, a candidate to be New York's next mayor.

Similar cases of misbehavior by costumed performers have been reported in Hollywood.

Disney did not respond to a request for comment, while the Sesame Workshop, the organization behind "Sesame Street," said it has not authorized such uses of any its characters in any city and is looking into what actions it can take.

Anthony Elia, a New York lawyer in the intellectual-property field, said the entertainment groups probably have a case for trademark infringement, but "the challenge probably would be getting a bunch of self-employed entrepreneurial individuals to stop."

It's not the easiest way to make a living. On a day when temperatures pushed 80, they sweated in their outfits, coming out from under their oversized costume heads only to grab a hot dog or a smoke. When one posed for a photo, two or three others dashed over and joined in.

"Want to take a picture?" a furry red Elmo asked a tourist. Moments later, he declined to speak to a reporter, saying through his costume, "I no speak English."

A Minnie Mouse offered a toddler in a stroller her hand and positioned herself at the handlebar. A Super Mario rushed over to join her.

"She said, `Can you give us money?"' said the child's mother, Melanie Somogyi of Hamilton, Ontario. "And they grabbed the stroller!"

Astronomy algorithms help detect aggressive cancers

Cancer researchers are teaming up with astronomers using computerized algorithms designed for viewing distant galaxies to spot biomarkers that can indicate the aggressiveness of a tumor, Medical News Today reported.

The method pathologists currently use for finding out the aggressiveness of a tumor involves looking through a microscope at a stained tumor sample to identify different proteins and cell changes. A computerized system would speed up the process.

In a study published in the British Journal of Cancer, teams from the Cancer Research U.K. Cambridge Institute, and both the Department of Oncology and the Institute of Astronomy at the University of Cambridge in the U.K. looked at more than 2,000 breast cancer tumors to determine the levels of three proteins known to be biomarkers for aggressive cancer.

"We've exploited the natural overlap between the techniques astronomers use to analyze deep sky images from the largest telescopes and the need to pinpoint subtle differences in the staining of tumor samples down the microscope," lead author, Dr. Raza Ali, a pathology fellow from the Cancer Research U.K. Cambridge Institute, said in a statement.

Researchers analyzed each tumor sample both manually with a pathologist using a microscope and automatically with a computer using adapted algorithms. When they compared the results, they found the computer algorithms came to the same conclusion as the pathologists up to 96 percent of the time.

"The results have been even better than we'd hoped; with our new automated approach performing with accuracy comparable to the time-consuming task of scoring images manually, after only relatively minor adjustments to the formula," said Ali.

The researchers now plan to do a large-scale, international study, using tumor samples from more than 20,000 breast cancer patients.

"Modern techniques are giving us some of the first insights into the key genes and proteins important in predicting the success or failure of different cancer treatments,” said senior author Carlos Caldas, a professor at the Cancer Research U.K. Cambridge Institute. “But before these can be applied in the clinic, their usefulness needs to be verified in hundreds or sometimes thousands of tumor samples."

New methods are already helping researchers analyze up to 4,000 images a day, Caldas added.
