'Prince Avalanche' Trailer: Paul Rudd And Emile Hirsch Hit The Road

Before making three films in positioned squarely in the stoner comedy genre, director David Gordon Green specialized in small, idiosyncratic movies like "George Washington" and "All the Real Girls." His latest film, "Prince Avalanche," which stars Emile Hirsch and Paul Rudd, is Green's attempt to strip away the excess of his last three theatrical efforts [...]

China first-quarter GDP likely nudged higher, recovery on track

BEIJING (Reuters) - China's annual rate of economic growth likely nudged higher in the first three months of 2013 versus the last quarter of 2012, with fixed asset investment and factory output growth in double digits cementing a mild rebound, according to a Reuters poll.

Evidence of a second successive quarter of rising year-on-year growth will further reinforce the view of investors that China's government has successfully engineered a recovery from 2012's 13-year low of 7.8 percent that is gaining traction.

Meanwhile with the annual rate of consumer inflation expected to ease to 2.4 percent from February's 10-month high of 3.2 percent, the urgency for policymakers to begin tightening monetary conditions at an early stage in the recovery cycle is reduced.

"We estimate GDP grew at a faster year-on-year pace of 8.1 percent in Q1," analysts at China International Capital Corp (CICC) wrote in a note to clients, outlining their calls for the March data cycle.

That is above the 8.0 percent consensus of 19 economists polled by Reuters and is driven largely by expectations of a stronger than anticipated contribution to growth of real estate sales.

CICC analysts calculate that property sales will contribute about 1 percentage point more to growth in Q1 than in Q4 last year, offsetting slowing growth in wholesale, retail and other industries.

Retail sales growth has been curtailed in recent months since the government launched an internal austerity drive at the end of last year, designed to cut down excessive banqueting and gift-giving that is often linked to corruption.

Economists in the Reuters poll expect retail sales to have expanded by 12.5 percent in March, slightly higher than the 12.3 percent rate seen in the combined January-February period, but still around 2-3 percentage points lower than typically seen through 2012.

Fixed asset investment, closely tied to real estate transactions, has seen a gentle upswing since around the middle of last year when China's Communist Party government decided to take action to underpin economic growth hit by faltering demand for the country's exports.

Gross exports account for around a third of economic output in China and a drop off in orders as the United States and the European Union - the country's two biggest customers - dealt with their own economic problems was felt through the Chinese factory sector.

Fixed asset investment is forecast to have expanded at an annual pace of 21.3 percent year-to-date in March, a whisker higher than the 21.2 percent pace in the first two months of 2013.

The downside risks to economic growth, however, are similarly tied to real estate, investment in which was worth 13.8 percent of GDP in 2012 and directly impacts around 40 other business sectors in the economy.

Rising real estate prices, alongside rising fixed asset investment, have sparked concerns that home costs could start to spiral out of control and lead the government to declare that a raft of measures to calm frothy prices must be strictly enforced.

That has led investors to start fretting that tighter property policies could constrain the overall economy.

That is a significant risk given that construction was the main driving force behind a rise in the fast-growing services sector of the economy in March, according to a survey of purchasing managers.

The real estate crackdown was one of the key reasons cited by Bank of America/Merrill Lynch in late March when it cut its Q1 annual growth forecast to 7.9 percent from 8.3 percent.

"At present we see more downside than upside risk to our 7.9 percent year-on-year Q1 forecast," the bank wrote in a note to clients, outlining its March data forecasts.

A giant step toward miniaturization: Nanotechnology transforms molecular beams into functional nano-devices with controlled atomic architectures

Apr. 3, 2013 ? Bottom-up synthesis of nanowires through metal-catalyzed vapor phase epitaxy is a very attractive process to generate high-quality nanowires thus providing an additional degree of freedom in design of innovative devices that extend beyond what is achievable with the current technologies.

In this nano-fabrication process, nanowires grow through the condensation of atoms released from a molecular vapor (called precursors) at the surface of metallic nano-droplets. Gold is broadly used to form these nano-droplets. This self-assembly of nanowires takes place spontaneously at optimal temperature and vapor pressure and can be applied to synthesize any type of semiconductor nanowires.

However, to functionalize these nanomaterials a precise introduction of impurities is central to tune their electronic and optical properties. For instance, the introduction of group III and V impurities in a silicon lattice is a crucial step for optimal design and performance of silicon nanowire technologies. The accurate control of this doping process remains an outstanding challenge that is increasingly complex as a result of the relentless drive toward device miniaturization and the emergence of novel nanoscale device architectures.

In a recent development, a team of scientists from Polytechnique Montr?al (Canada), Northwestern University (USA), and Max Planck Institute of Microstructure Physics (Germany) led by Professor Oussama Moutanabbir has made a fascinating discovery of a novel process to precisely functionalize nanowires. By using aluminum as a catalyst instead of the canonical gold, the team demonstrated that the growth of nanowires triggers a self-doping process involving the injection of aluminum atoms thus providing an efficient route to dope nanowires without the need of post-growth processing typically used in semiconductor industry. Besides the technological implications, this self-doping implies atomic scale processes that are crucial for the fundamental understanding of the catalytic assembly of nanowires.

The scientists investigated this phenomenon at the atomistic-level using the emerging technique of highly focused ultraviolet laser-assisted atom-probe tomography to achieve three-dimensional atom-by-atom maps of individual nanowires. A new predictive theory of impurity injections was also developed to describe this self-doping phenomenon, which provides myriad opportunities to create entirely new class of nanoscale devices by precisely tailoring shape and composition of nanowires.

The results of their breakthrough will be published in Nature.

Facebook Home official, replaces your app icons with social info (video)

Today Facebook finally took the wraps off Home, a suite of apps and a home screen replacement for Android phones. It's not just a new UI for launching apps however; it replaces the lockscreen with Cover Feed and prioritizes updates from people instead of apps. There is a standard paginated launcher, that is always just a swipe away. But the focus is on the full-screen images that are your new welcome screen. These are status updates from friends that you can easily flip through and double tap to like when someone posts something exciting. Plain text status updates are placed over a user's cover photo, to keep the appearance consistent with photo-centric posts.

Notifications are presented as small cards, which Facebook applies an algorithm to, in order determine the updates that are most important to you. Just like with the standard Android UI you simply swipe notifications off screen to dismiss them. But, if you want to remove all of them in one shot, you long press a single notification and the rest will be drawn to it and you'll be able to dismiss the entire stack.

Airline to charge passengers by body weight

(Samoa Air)

Some airlines are beginning to charge obese customers for extra seats, but Samoa Air appears to be the first to adopt a "pay as you weigh" pricing plan.

The airline's price-per-kilogram will vary depending on the flight, from as little as $1 per kilogram to as much as $4.16, reports the Sydney Morning Herald.

In a radio interview this week, according to the paper, Samoa Air chief executive Chris Langton defended the new policy. "This is the fairest way of traveling," Langton said. "There are no extra fees in terms of excess baggage or anything?it is just a kilo is a kilo is a kilo."

Passengers now must type in their weight and the weight of their baggage into the online booking section of the airline's website.

"When you get into the Pacific, standard weight is substantially higher," Langton continued. "That's a health issue in some areas."

He said the new policy is intended, in part, to raise awareness of Samoa's weight problem.

The Pacific island nation has one of the most obese populations in the world. According to a 2007 World Health Organization survey, more than 80 percent of Samoans age 15 and older are considered obese, making it the sixth fattest nation in the world. Nauru, in the South Pacific, topped the list, with 94.5 percent of its 9,322 inhabitants obese.

Samoa Air operates a fleet of small BN2A Islander and Cessna 172 planes, some with as few as eight seats.

"Airlines don't run on seats, they run on weight, and particularly the smaller the aircraft you are in, the less variance you can accept in terms of the difference in weight between passengers," Langton said. "Anyone who travels at times has felt they have been paying for half of the passenger next to them."

He may be right. According to a 2010 survey conducted by Skyscanner.net, 76 percent of travelers said airlines should charge overweight passengers more if they needed an extra seat.

Last month in the Journal of Revenue and Pricing Management, Bharat Bhatta, a Norwegian economist, recommended that airlines adopt a "pay as you weigh" program.

"To the degree that passengers lose weight and therefore reduce fares, the savings that result are net benefits to the passengers," Bhatta wrote.
