385 new HIV cases in S'pore between Jan & Oct

SINGAPORE: From January to October this year, 385 new cases of human immunodeficiency virus (HIV) were reported among Singapore residents, said the health ministry on Thursday.

The Ministry of Health (MOH) expects the total number of notified HIV cases in 2012 to be similar to that of 2011, when there were 461 cases.

In the first six months of this year, 215 new cases of HIV, which causes acquired immunodeficiency syndrome (AIDS), were reported.

Between July and October, there were 170 new cases.

MOH said among the cases reported between January and June, 92 per cent (198) were males and 8 per cent (17) were females.

Most of them caught the virus through sex.

Half of those infected had heterosexual sex, while 43 per cent were infected from homosexual transmission, and 4 per cent from bisexual transmission.

About half, or 47 per cent, of those infected were between 30 and 49 years.

63 per cent were single, 23 per cent were married and 10 per cent were divorced or separated.

Half of the new cases reported between January and June already had late-stage HIV infection when they were diagnosed, similar to the pattern in previous years.

Slightly more than half found out they had the virus during HIV testing, as part of medical care.

Another 15 per cent were detected through health screening.

14 per cent were detected during voluntary HIV screening and the rest found out they were HIV-positive through contact tracing and other screening methods.

A higher proportion of homosexuals - or 28 per cent - were detected during voluntary screening, compared with 4 per cent for heterosexuals.

MOH and the Health Promotion Board (HPB) have urged individuals to protect themselves from HIV infection by following the principles of "ABCD": abstinence, being faithful, correct and consistent use of condoms and early detection.

Apple branches out with new campus in Santa Clara

Apple's proposed new headquarters would be able to fit all of its employees but has yet to be built.

As delays have hampered the construction of Apple's proposed upcoming spaceship-like headquarters, the tech giant has begun construction on a two-building campus in nearby Santa Clara, Calif., to house its overflow of employees, according to the Oakland Tribune.

Apple agreed to lease the Santa Clara site, which is close to its current Cupertino headquarters, and plans to move in by 2014. Now under construction, this office will be nearly 296,000 square feet, take up two six-story buildings, and accommodate at least 1,200 employees.

Apple has been making moves to find extra space to fit employees around Silicon Valley, leasing office space well outside of its Cupertino headquarters, which can hold about 2,800 employees. The company has some 12,000 employees in the area, which led the company to pitch plans to the city of Cupertino last year to build a new headquarters that can fit up to 14,200 people.

This new headquarters is designed to be a gigantic circular building, which somewhat resembles the Pentagon and is slated to be completed by mid-2016. Originally, Apple hoped to move into its new digs in 2015, but the city of Cupertino hasn't yet completed its environmental impact survey, so construction has been pushed back until next year.

CNET contacted Apple for comment. We'll update the story when we get more information.

Caterpillar Fungus Has Anti-Inflammatory Properties

In the Tibetan mountains, a fungus attaches itself to a moth larva burrowed in the soil. It infects and slowly consumes its host from within, taking over its brain and making the young caterpillar move to a position from which the fungus can grow and spore again.

Sounds like something out of science fiction, right? But for ailing Chinese consumers and nomadic Tibetan harvesters, the parasite called cordyceps means hope—and big money. Chinese markets sell the "golden worm," or "Tibetan mushroom"—thought to cure ailments from cancer to asthma to erectile dysfunction—for up to $50,000 (U.S.) per pound. Patients, following traditional medicinal practices, brew the fungal-infected caterpillar in tea or chew it raw.

Now the folk medicine is getting scientific backing. A new study published in the journal RNA finds that cordycepin, a chemical derived from the caterpillar fungus, has anti-inflammatory properties.

"Inflammation is normally a beneficial response to a wound or infection, but in diseases like asthma it happens too fast and to too high of an extent," said study co-author Cornelia H. de Moor of the University of Nottingham. "When cordycepin is present, it inhibits that response strongly."

And it does so in a way not previously seen: at the mRNA stage, where it inhibits polyadenylation. That means it stops swelling at the genetic cellular level—a novel anti-inflammatory approach that could lead to new drugs for cancer, asthma, diabetes, rheumatoid arthritis, and cardiovascular-disease patients who don't respond well to current medications.

From Worm to Pill

But such new drugs may be a long way off. The science of parasitic fungi is still in its early stages, and no medicine currently available utilizes cordycepin as an anti-inflammatory. The only way a patient could gain its benefits would by consuming wild-harvested mushrooms.

De Moor cautions against this practice. "I can't recommend taking wild-harvested medications," she says. "Each sample could have a completely different dose, and there are mushrooms where [taking] a single bite will kill you."

Today 96 percent of the world's caterpillar-fungus harvest comes from the high Tibetan Plateau and the Himalayan range. Fungi from this region are of the subspecies Ophiocordyceps sinensis, locally known as yartsa gunbu ("summer grass, winter worm"). While highly valued in Chinese traditional medicine, these fungi have relatively low levels of cordycepin. What's more, they grow only at elevations of 10,000 to 16,500 feet and cannot be farmed. All of which makes yartsa gunbu costly for Chinese consumers: A single fungal-infected caterpillar can fetch $30.

Brave New Worm

Luckily for researchers, and for potential consumers, another rare species of caterpillar fungus, Cordyceps militaris, is capable of being farmed—and even cultivated to yield much higher levels of cordycepin.

De Moor says that's not likely to discourage Tibetan harvesters, many of whom make a year's salary in just weeks by finding and selling yartsa gunbu. Scientific proof of cordycepin's efficacy will only increase demand for the fungus, which could prove dangerous. "With cultivation we have a level of quality control that's missing in the wild," says de Moor.

"There is definitely some truth somewhere in certain herbal medicinal traditions, if you look hard enough," says de Moor. "But ancient healers probably wouldn't notice a 10 percent mortality rate resulting from herbal remedies. In the scientific world, that's completely unacceptable." If you want to be safe, she adds, "wait for the medicine."

Ancient Chinese medical traditions—which also use ground tiger bones as a cure for insomnia, elephant ivory for religious icons, and rhinoceros horns to dispel fevers—are controversial but popular. Such remedies remain in demand regardless of scientific advancement—and endangered animals continue to be killed in order to meet that demand. While pills using cordycepin from farmed fungus might someday replace yartsa gunbu harvesting, tigers, elephants, and rhinos are disappearing much quicker than worms.

Huge Jackpot Looms, but Can Money Buy Happiness?

Nov 28, 2012 1:02pm

Can money buy happiness? If you’re clutching several Powerball tickets in one hand as you thumb through yacht and pony catalogs with the other, you’re probably betting yes.

We’re all told the odds of winning are abysmal — about 1 in 175 million — but let’s assume you win the $500 million jackpot. Experts say the initial euphoria will wear off relatively quickly and you’ll be left with pretty much the same dismal outlook on life you’ve always had.

“Winning will release some pleasurable chemicals in your brain over the short term,” said Scott Bea, a clinical psychologist with the Cleveland Clinic in Ohio. “Unfortunately, your brain will likely revert back to the same old same old before too long.”

Bea conceded that the extra bushels of cash would ease any anxiety over paying the bills, and you’d probably get an additional rush of those joy-boosting neuro-hormones when you went on a shopping spree, but ultimately the basal ganglia, the part of your brain that tends to dwell on the negative, will kick in and you’ll be back to your usual miserable self in no time.

Why? Because in its dark little heart, the brain is a pessimistic organ. Studies show bad memories tend to be far stickier than pleasant memories. And as Bea pointed out, complaints are the topic of nearly 70 percent of all conversation. So according to this logic, you’re less likely to relive the glory of your jackpot moment than you are to grouse about all the fifth cousins suddenly friending you on Facebook to ask for a handout.

Bea also said big winners who aren’t careful to cultivate happiness skills such as optimism, a charitable attitude and savvy money management habits often wind up in more wretched circumstances than where they started. History is certainly littered with such examples.

Back in the 1980s, Evelyn Adams won the New Jersey lottery not once, but twice. She quickly gambled away all $5.4 million and today she’s flat broke, living in a trailer park. Then there’s Billy Bob Harrell Jr. a Pentecostal preacher who was working as a stock boy in 1997 when he scored a cool $31 million in the Texas lottery. The stress of winning so overwhelmed him that he divorced his wife and committed suicide.

Does this mean you should hope the odds work against you when they draw those lucky numbers at 10:59 ET tonight? According to Bea, not at all.

“For most people, purchasing a ticket and fantasizing about what life will be like once you’ve won is the most pleasant part of the lottery experience,” he said, “You could probably flush the same amount of money down the toilet and get much the same result — but then you wouldn’t have the dream.”

Gas explosion in Springfield points to ageing pipes

Human error and corroded pipes were a catastrophic combination on 23 November when a natural gas explosion in Springfield, Massachusetts, injured 21 people and damaged more than 40 buildings.

Gas company officials attributed the incident to an employee puncturing a high-pressure pipeline with a metal probe while looking for a leak. However, the steel pipeline was highly corroded, making it susceptible to damage, according to Mark McDonald, president of the New England Gas Workers Association. "You would have to be Superman to go through steel pipe in good condition," he says.

Ageing natural gas pipelines in the US are increasingly coming under scrutiny. A recent study found 3356 leaks from pipelines under Boston alone. Twenty-five thousand leaks have been reported throughout Massachusetts, some of which have been leaking continuously for more than 20 years, McDonald says. "Enough is enough," he says. "We have to fix the leaks and maintain the gas lines."

The leaks raise safety concerns, and have implications for global warming. Methane is thought to be more than 20 times more effective at trapping heat in the atmosphere than carbon dioxide over a 100 year period.

Incidents involving natural gas pipelines in the US cause an average of $133 million in property damage each year according to data collected by the US Pipeline and Hazardous Materials Safety Administration. Even accounting for inflation, annual damages are several times higher today than they were 20 years ago.

Maldives defends scrapping India airport deal

COLOMBO: The Maldives defended Wednesday its controversial decision to terminate an airport management contract with an Indian firm, saying the deal was dogged by "legal, technical and economic issues".

President Mohamed Waheed's government gave five days to GMR Group to leave after prematurely ending the 25-year lease of the nation's main international airport for a one-time fee of $78 million and revenue share thereafter.

The government said it was advised by unnamed British and Singaporean lawyers to abrogate the agreement, prompting India to warn that the move could scare away foreign investors from the archipelago.

"The cabinet decided to terminate... on grounds that there were many legal, technical and economic issues regarding the agreement, and that it was legally invalid, and impossible to further continue," Waheed's office said.

Waheed's government had objected to the privatisation carried out by his predecessor Mohamed Nasheed, the country's first democratically elected leader who quit earlier this year and claimed he was forced out.

There was no immediate comment from GMR that ran the airport -- which handles 2.6 million passengers a year -- since November 2010 together with Malaysia Airports Holdings Berhad. GMR held a 77 per cent stake in the operation.

Former leader Nasheed who initiated the deal with GMR described the termination as a major blow to foreign investment and tourism, the country's main source of foreign exchange.

"This decision is bad for tourism, bad for the economy and bad for the Maldivian people," Nasheed said in a statement. "This will put off potential investors for decades."

He accused his successor of leading the nation of 330,000 Sunni Muslims "down the path to economic ruin".

The Indian foreign ministry has said that they will closely monitor the developments and asked the Maldivian government to ensure the safety of Indian nationals in the country.

Half of mobile phone users get online with their device

People are now using their cell phones for much more than talking. According to a new study by the Pew Internet & American Life Project, 85 percent of U.S. adults own a mobile phone and 56 percent of them use it to get online.

"Fully 85 percent of American adults own a cell phone and now use the devices to do much more than make phone calls," Pew's Maeve Duggan and Lee Rainie wrote in the recently released study. "Cell phones have become a portal for an ever-growing list of activities."

The data is based on surveys conducted in March and August, which polled more than 4,500 cell phone owners about their habits. The survey didn't clarify what percentage of those polled owned a smartphone, but a Pew poll that came out in April showed that roughly 46 percent of American adults own a smartphone.

Interestingly, this number isn't much higher than a year ago. In July 2011, Pew data showed that 83 percent of U.S. adults have a cell phone and 35 percent own a smartphone.

Despite the small amount of growth, Pew's new survey does suggest that mobile devices are spurring more people to get online and spend more time online. For example, those people using the Internet has gone from 25 percent in 2008 to 56 percent today. And, only 22 percent of people downloaded apps in 2009, while 43 percent do so now. Whether people are taking photos, e-mailing, texting, or getting online, they are now doing more with their cell phones.

Pictures: Falcon Massacre Uncovered in India

Photograph courtesy Conservation India

A young boy can sell bundles of fresh Amur falcons (pictured) for less than five dollars. Still, when multiplied by the thousands of falcons hunters can catch in a day, the practice can be a considerable financial boon to these groups.

Since discovering the extent of Amur hunting in Nagaland this fall, Conservation India has taken the issue to the local Indian authorities.

"They have taken it very well. They've not been defensive," Sreenivasan said.

"You're not dealing with national property, you're dealing with international property, which helped us put pressure on [them]." (Related: "Asia's Wildlife Trade.")

According to Conservation India, the same day the group filed their report with the government, a fresh order banning Amur hunting was issued. Local officials also began meeting with village leaders, seizing traps and confiscating birds. The national government has also requested an end to the hunting.

Much remains to be done, but because the hunt is so regional, Sreenivasan hopes it can eventually be contained and stamped out. Authorities there, he said, are planning a more thorough investigation next year, with officials observing, patrolling, and enforcing the law.

"This is part of India where there is some amount of acceptance on traditional bush hunting," he added. "But at some point, you draw the line."

Petraeus Scandal: Socialite Jill Kelley Fighting Back

Tampa socialite Jill Kelley is fighting back. Today, sources close to the woman who was caught in the media crossfire during the David Petraeus sex scandal have released new letters aimed at reclaiming her reputation.

In a letter released to reporters by Jill Kelley's spokesperson, Kelley's attorney goes after a New York businessman who claimed Kelley was using her connections to Petraeus to broker a deal with the South Korean government.

"It is impossible to overlook your attempt to get your '15 minutes of fame,'" attorney Abbe Lowell wrote to Adam Victor, the president and CEO of TransGas Development Systems. "…You have the right to do that to yourself, but you do not have the right to defame our client.

"This letter is notice to you that statements you have made are false and defamatory and are intended to portray Ms. Kelley in a false light," the letter continued.

Victor has claimed that Kelley asked for $80 million in commissions to arrange a deal between Victor and the South Korean government. Kelley was an honorary consul for the Republic of South Korean.

"While it is certainly true that Ms. Kelley communicated with you about a potential business deal, it has nothing to do with General Petraeus or other military," Lowell wrote Victor.

The dealings between Jill Kelley and Adam Victor were detailed in a series of emails between the two made public earlier this month. The emails appeared to confirm the New York businessman's claim that Kelley wanted a huge fee for brokering a transaction with the South Korean government.

But in his letter to Victor, Lowell denies that Kelley wanted anything close to $80 million, and says the full chain of emails reveal that "it was you (Victor) who were trying to capitalize on her contacts, and not the other way around."

Kelley and Victor were introduced at the Republican National Convention in Tampa in August by Kelley's friend, Tampa real estate developer Don Phillips. In an interview with ABC News, Phillips said he suggested that Kelley and Victor should meet because Kelley could help Victor land a deal for a coal gasification plant in South Korea.

Phillips claimed that Kelley said that Victor tried to "proposition" her "almost immediately," and said he had to cajole her into flying to New York for a second meeting with Victor.

After she met with Victor in New York, Phillips said, Kelley reported that she was no longer interested in pursuing the deal. According to Phillips, she said, "As a result of my personal investigations and business intelligence this is just not going anywhere, Don, and you just don't want to associate with this guy."

Victor, who denies propositioning Kelley, claimed she continued pushing for the deal after their meeting in New York. But sources close to Kelley say that telephone voice messages Victor left for Kelley reveal that he was the one who continued to seek Kelley's involvement, even after the Petraeus affair came to light.

Victor also claims that Kelley told him Petraeus arranged for her to be named honorary consul, and that she could use her connections with high-level Korean officials to help land the coal plant deal.

None of the emails that Victor showed to ABC News mention Petraeus. Kelley's friend Don Phillips told ABC News that Kelley has not "in any way tried to profit" from her relationship with Petraeus.
