Get a MacBook Air for $799.99

I've never been more tempted to buy a Mac than I am at this very moment. As you know from my recent rant, I'm none too pleased with Windows at the moment, and I've long considered the MacBook Air one of the most drool-worthy laptops on the planet.

Ah, but the "Apple tax" was always a little too steep for me. I just couldn't justify spending $1,000 for a laptop, even one so super-sexy. Today, however, I might just pull the trigger.

Today only, and while supplies last, Best Buy has the Apple MacBook Air model MD223LL/A for $799.99 shipped (plus sales tax where applicable). It's new, not refurbished, and $200 less than what Apple charges. That kind of price break just doesn't come around very often.

This is the 11.6-inch
MacBook Air, stocked with a 1.7GHz Intel Core i5 processor, 4GB of RAM, a 64GB SSD, and all the other standard Air amenities. (Also available: the 13.3-inch Air for $999.99!)

Especially impressive, it weighs just 2.4 pounds and measures a scant 0.7 inches thick. Every time I'm around one, I can't help muttering, "The precioussss."

Now, practically speaking, I can still buy an equally powerful Windows laptop for half the price. (Here's an Asus with a touchscreen for $399 when you use this printable coupon.) It won't be as thin or light or lust-worthy, but it'll get the job done.

On the flipside, maybe it's finally time to see if all the "it just works" hype is justified. Quick! Somebody distract Mrs. Cheapskate while I go for the credit card!

Anyway, I suspect this may sell out, as it really is an unusually good deal. If you're in the market for a "preciousss," grab this while you can.

Bonus deal: The game deals just keep on coming! For a limited time, Amazon has the Crazy Action Pack (PC) and 2K Shooter Pack (PC) for $9.99 each. The first bundle comes with Borderlands: Game of the Year Edition, Darkness II, and Duke Nukem Forever. The second includes BioShock, BioShock II, and Duke Nukem Forever. (Looks like 2K Games will do anything to unload ol' Duke.) Also available: Max Payne 3 (PC) for $14.99. Good heavens, what do I play first?!

Deformed Dolphin Accepted Into New Family

In 2011, behavioral ecologists Alexander Wilson and Jens Krause of the Leibniz-Institute of Freshwater Ecology and Inland Fisheries in Germany were surprised to discover that a group of sperm whales (Physeter macrocephalus)—animals not usually known for forging bonds with other species—had taken in an adult bottlenose dolphin (Tursiops truncatus).

The researchers observed the group in the ocean surrounding the Azores (map)—about 1,000 miles (1,600 kilometers) off the coast of Lisbon, Portugal—for eight days as the dolphin traveled, foraged, and played with both the adult whales and their calves. When the dolphin rubbed its body against the whales, they would sometimes return the gesture.

Among terrestrial animals, cross-species interactions are not uncommon. These mostly temporary alliances are forged for foraging benefits and protection against predators, said Wilson.

They could also be satisfying a desire for the company of other animals, added marine biologist John Francis, vice president for research, conservation, and exploration at the National Geographic Society (the Society owns National Geographic News).

Photographs of dogs nursing tiger cubs, stories of a signing gorilla adopting a pet cat, and videos of a leopard caring for a baby baboon have long circulated the Web and caught national attention.

A Rare Alliance

And although dolphins are known for being sociable animals, Wilson called the alliance between sperm whale and bottlenose dolphin rare, as it has never, to his knowledge, been witnessed before.

This association may have started with something called bow riding, a common behavior among dolphins during which they ride the pressure waves generated by the bow of a ship or, in this case, whales, suggested Francis.

"Hanging around slower creatures to catch a ride might have been the first advantage [of such behavior]," he said, adding that this may have also started out as simply a playful encounter.

Wilson suggested that the dolphin's peculiar spinal shape made it more likely to initiate an interaction with the large and slow-moving whales. "Perhaps it could not keep up with or was picked on by other members of its dolphin group," he said in an email.

Default

But the "million-dollar question," as Wilson puts it, is why the whales accepted the lone dolphin. Among several theories presented in an upcoming paper in Aquatic Mammals describing the scientists' observations, they propose that the dolphin may have been regarded as nonthreatening and that it was accepted by default because of the way adult sperm whales "babysit" their calves.

Sperm whales alternate their dives between group members, always leaving one adult near the surface to watch the juveniles. "What is likely is that the presence of the calves—which cannot dive very deep or for very long—allowed the dolphin to maintain contact with the group," Wilson said.

Wilson doesn't believe the dolphin approached the sperm whales for help in protecting itself from predators, since there aren't many dolphin predators in the waters surrounding the Azores.

But Francis was not so quick to discount the idea. "I don't buy that there is no predator in the lifelong experience of the whales and dolphins frequenting the Azores," he said.

He suggested that it could be just as possible that the sperm whales accepted the dolphin for added protection against their own predators, like the killer whale (Orcinus orca), while traveling. "They see killer whales off the Azores, and while they may not be around regularly, it does not take a lot of encounters to make [other] whales defensive," he said.

Alleged Doctor Killer Had Anger Issues, Friend Says

Jason Smith, the Philadelphia exterminator who police say showed up at the home of Dr. Melissa Ketunuti this week to solve her rodent problem before strangling her, was a problem child as an adolescent, a family friend told ABC News.

The family friend from many years ago, who asked for anonymity, said Smith, 36, had behavior and anger issues, and that he also liked to set things on fire.

After Smith and Ketunuti got into "some kind of argument" in Ketunuti's basement, he struck her, strangled her and set her on fire, according to police.

Smith reportedly admitted to the brutal slaying after hours of police questioning Wednesday night.
Smith told police that Ketunuti had "belittled" him, sources told ABC News affiliate WPVI-TV in Philadelphia

He snapped and apparently tried to hide any evidence by setting the 35-year-old doctor on fire with paper he lit in the kitchen, the station reported.

Philadelphia Doctor's Murder Leaves Police Baffled Watch Video

"People like Mr. Smith basically walk around with a huge chip on their shoulder, and they feel so inadequate and so insecure that any perceived belittlement of them will set them off," ABC News consultant and former FBI agent Brad Garrett said.

Capt. James Clark of the Philadelphia Police Department said Smith's mood and clarity varied during his alleged confession.

"At some points, he was solemn. At other points, it was like he was in a fog," Clark said at a news conference.

Smith has been charged with murder, arson, abuse of a corpse and risking a catastrophe.

Ori Feibush, who owns a coffee shop near Ketunuti's street, said he and police pored over hours of surveillance video until they saw Ketunuti walking home from doing errands, with Smith steps behind her.

"Forty-five minutes later, we see this same guy walking past, but [he] looks a little more disheveled and he's got gloves on," Feibush told ABC News.

Police say that after the slaying, Smith circled Ketunuti's block twice, before heading off to another job.

Ketunuti was a doctor at the Children's Hospital of Philadelphia and had lived alone in the Graduate Hospital neighborhood of the city for about three years. Her family released a statement saying they are "devastated by this senseless act of violence."

"Melissa's friends from childhood, college, residency and elsewhere remember her many kindnesses, even during long hours, as well as her zest for life: traveling, running and spending time with friends and family," the statement said. "Melissa was a source of joy to everyone in her life. Her passing has left an enormous gap in our lives."

Private home prices expected to be relatively stable: analyst

SINGAPORE: Colliers International said private home prices are expected to remain relatively stable with marginal downside this year, thanks to the government's latest cooling measures imposed in January 2013.

In the face of mounting supply, rents are also expected to weaken this year.

According to a report by Colliers International, average monthly gross rents of luxury/super-luxury homes are expected to decline by up to a maximum of 10 per cent in 2013.

Meanwhile, Colliers said Singapore's residential property market saw a record breaking year in 2012.

This was despite noticeably subdued market activity in the fourth quarter of 2012, following recent property cooling measures.

Colliers said the home buying frenzy which started in January last year brought developers' sales volumes for 2012 to a record high as early as September.

This was boosted by a record number of new units released by developers as well.

4,283 new units were sold in the fourth quarter of last year, raising the primary sales volume to 22,127 units for the whole of 2012.

This breaks the previous record of 16,292 new units sold in 2010 by 35.8 per cent.

Meanwhile, developers launched a total of 21,511 new private homes last year, surpassing the previous highs of 17,710 units recorded in 2011 by 21.5 per cent.

But on a quarterly basis, developer launches and sales volumes dipped below 5,000 units last quarter due to the traditional year-end festive and holiday season and a weaker sentiment.

The number of new units released fell from an average of 6,023 units for the first three quarters to 3,441 in the last quarter of 2012.

Similarly, developer sales in the three months ending December 2012 fell 27.6 per cent on-quarter to 4,238 units from 5,916 units sold from July to September.

Meanwhile, mass market projects located in the Outside Central Region (OCR) dominated activities in the primary market in the last three months of 2012, contributing to 51.0 per cent of developer launches and 63.1 per cent of developer sales during this period.

Homes in the Rest of the Central region (RCR) contributed 31.5 per cent of island-wide launches and 22.8 per cent of developer sales in three months ending December 2012.

The Colliers report also stated that the narrowing price gap between mid-tier and mass market homes located in suburban areas saw home-buyers committing to 975 new units in 4Q2012, up 19.8 per cent on quarter from the 814 units sold in the third quarter of last year.

Launches and sales of new homes in the Core Central Region (CCR) meanwhile accounted for 17.5 per cent and 14.1 per cent of island-wide launch and sales volumes in 4Q2012.

Developer launches in that segment also slid 2.4 per cent from the third quarter while sales dropped 6.5 per cent on-quarter during the October to December period.

All three market regions (OCR, RCR and CCR) experienced higher rates of price growth in 2012, although the pace of price increase varied across the different regions.

Google asks FCC for wireless spectrum, but don't get too excited

Google has petitioned the Federal Communications Commission (FCC) for permission to apparently conduct testing on, well, something. But it's not a new wireless service some have hoped it would be, CNET has exclusively learned.

Steven Crowley, a wireless engineer, discovered the application, which was filed by Google last week. The application asks for permission to test frequencies across the 2524 to 2546 MHz range and 2567 to 2625 MHz range. According to Crowley, those ranges are reserved for Educational Broadband Service and Broadband Radio Service. But here's the catch: Clearwire, a company that Google had owned a slice in until last year, uses the ranges for its mobile broadband service.

Predictably, that has prompted speculation over whether Google is testing its own wireless network. The company currently offers free Wi-Fi service in the Chelsea neighborhood in New York City, and has been dipping its toe in the service waters with Google Fiber in Kansas City.

Google, however, has not provided any details on its plans in the FCC petition. The report is heavily redacted and includes only one exhibit outlining where it will place base stations to test the service in its Mountain View headquarters.

Given the relative inability of concrete information, some circumstantial evidence is being drawn to guess at Google's plans. The filing, for example, was authorized by Google vice president of Access Services, Milo Medin. Google's Access Services handles its Fiber offering and wireless initiatives.

However, the spectrum range in question currently does not work natively with any popular consumer devices. In addition, a source with knowledge of Google's plans, has told CNET that the testing is just that, and at this time, the search giant has no plans to deliver a consumer-facing service with the spectrum.

So, what is Google up to with this testing? At this point, according to the source, it's nothing we'll be using, and falls in line with Access Services' charge of regularly testing wireless technologies.

Google declined CNET's request for comment on the report.

N. Korea Vows More Nuke Tests Targeting U.S.

In a bellicose statement singling out the United States as the "sworn enemy" of the Korean people, North Korea today announced plans for a third nuclear test and continued rocket launches.

The move is seen as a disappointment to those who hoped the country's new leader, Kim Jong-Un, might take a less aggressive path than his predecessor and father, Kim Jong-il.

It is also seen as a direct challenge to President Obama and South Korea's newly elected president, Park Geun-hye, who takes office next month.

The statement from North Korea's National Defense Commission read:

"Settling accounts with the U.S. needs to be done with force, not with words as it regards jungle law as the rule of its survival."

The renewed threats come in response to the U.S. backed resolution tightening sanctions against North Korea after its December rocket launch.

At that time, North Korea repeatedly insisted that the launch was simply part of its peaceful space program. The recent statement made no mention of that.

It read: "We are not disguising the fact that the various satellites and long-range rockets that we will fire and the high-level nuclear test we will carry out are targeted at the United States."

South Korean officials analyzed debris from the December launch that, they say, indicates North Korea built and tested crucial components for a missile that can fly further than 6,200 miles.

Analysts say that preparations at the Pungyee test site in northeastern North Korea are underway and that a new underground test could take place on short notice.

Within the international monitoring community it is not believed that North Korea currently has the capability to launch a long-range rocket with the capacity to reach the United States or the technology to mount a nuclear warhead on a long-range missile. But the U.S. is not pleased with North Korea's plans. Glyn Davies, the top U.S. envoy to the region, said in Seoul, "We hope they don't do it. We call on them not to do it."

China, North Korea's main ally in the region, is also urging restraint. China backed the U.S. resolution at the United Nations and today the Foreign Ministry cautioned North Korea not to take further steps to increase tension.

See ya, latex: Reinventing the condom

IF I didn't already know what they were, I would have difficulty identifying the objects in front of me. There are about 20, mounted on a rack of vertical wooden pegs and illuminated into ghostly shadows by a light box beneath. They resemble elaborate sculptures in translucent resin. One looks like a thin, hollow lemon juicer; others are like accordions or abstract spaceships.

Designers Danny Resnic and Ray Chavez joke that they used to keep these racks in the window since passers-by had no chance of guessing what they were. And it's true; they share only the most rudimentary qualities with what most people think of when they think of a condom.

Despite being available in various colours, flavours and textures, modern condoms all follow a basic design that has been with us for more than ...

PM Lee says he is aware of childcare concerns

SINGAPORE: Prime Minister Lee Hsien Loong has written on his Facebook page that he is aware many couples and parents are worried about childcare for their young children, especially when both adults are working.

He noted that they had raised their concerns and commented on this when he posted on the Marriage & Parenthood Package on Monday.

Mr Lee added that the government is increasing child and infant care subsidies, for families with a gross monthly income of up to S$7,500 and expanding the number of good quality and affordable childcare centres.

This will give parents with young children greater peace of mind, and hopefully encourage couples to have more children.
