Painted ladies fly to ISS


In a project known as Butterflies in Space, the Atlantis space shuttle will next week carry a butterfly habitat containing monarch and painted lady adults and larvae to the International Space Station.

Painted ladies fly to International Space StationThe idea is that thousands of schoolkids across the US will be able to study the effects of space travel on the little astronauts, comparing them with examples reared in their own classroms. The children will be able to monitor their progress via still and video images.

"One of the most exciting things about this project is that we can use the International Space Station to bring spaceflight experiments into classrooms around the country," said BioServe Director Louis Stodieck, principal investigator on the project. "Our continuing goal is to inspire K-12 students around the country in science, technology, engineering and math."

The butterfly payload has been designed and built by BioServe Space Technologies in CU-Boulder's aerospace engineering department and will carry two butterfly habitats containing monarch and painted lady butterfly larvae and enough nectar and other food to support them as they develop.

Record Highs Far Outpace Record Lows Across U.S.

Spurred by a warming climate, daily record high temperatures occurred twice as often as record lows over the last decade across the continental United States, new research shows. The ratio of record highs to lows is likely to increase dramatically in coming decades if emissions of greenhouse gases continue to climb.

Results of the research, by authors at the National Center for Atmospheric Research (NCAR) in Boulder, CO, Climate Central, The Weather Channel, and the National Oceanic and Atmospheric Administration (NOAA), have been accepted for publication in the American Geophysical Union journal Geophysical Research Letters.

"Climate change is making itself felt in terms of day-to-day weather in the United States," says NCAR scientist Gerald Meehl, the lead author. "The ways these records are being broken show how our climate is already shifting."

The research was funded by the National Science Foundation (NSF), NCAR's sponsor, the U.S. Department of Energy, and Climate Central.

"This intriguing study provides new evidence of climate change," says Steve Nelson, NSF program director for NCAR. "And it's change that's affecting our daily lives."

If temperatures were not warming, the number of record daily highs and lows being set each year would be approximately even. Instead, for the period from January 1, 2000, to September 30, 2009, the continental United States set 291,237 record highs and 142,420 record lows, as the country experienced unusually mild winter weather and intense summer heat waves. A record daily high means that temperatures were warmer on a given day than on that same date throughout a weather station's history.

The authors used a quality control process to ensure the reliability of data from thousands of weather stations across the country, while looking at data over the past six decades to capture longer-term trends. This decade's warming was more pronounced in the western United States, where the ratio was more than two to one, than in the eastern United States, where the ratio was about one-and-a-half to one. The study also found that the two-to-one ratio across the country as a whole could be attributed more to a comparatively small number of record lows than to a large number of record highs.

This indicates that much of the nation's warming is occurring at night, when temperatures are dipping less often to record lows. This finding is consistent with years of climate model research showing that higher overnight lows should be expected with climate change.

In addition to surveying actual temperatures in recent decades, Meehl and his co-authors turned to a sophisticated computer model of global climate to determine how record high and low temperatures are likely to change during the course of this century. The modeling results indicate that, if nations continue to increase their emissions of greenhouse gases in a "business as usual" scenario, the U.S. ratio of daily record high to record low temperatures would increase to about 20-to-1 by mid-century and 50-to-1 by 2100. The mid-century ratio could be much higher if emissions rose at an even greater pace, or it could be about 8-to-1 if emissions were reduced significantly, the model showed.

The authors caution that such predictions are, by their nature, inexact. Climate models are not designed to capture record daily highs and lows with precision, and it remains impossible to know future human actions that will determine the level of future greenhouse gas emissions.

The model used for the study, the NCAR-based Community Climate System Model, correctly captured the trend toward warmer average temperatures and the greater warming in the West, but overstated the ratio of record highs to record lows in recent years. However, the model results are important because they show that, in all likely scenarios of future greenhouse gas emissions, record daily highs should increasingly outpace record lows over time.

"If the climate weren't changing, you would expect the number of temperature records to diminish significantly over time," says Claudia Tebaldi, a statistician with Climate Central who is one of the paper's co-authors. "As you measure the high and low daily temperatures each year, it normally becomes more difficult to break a record after a number of years. But, as the average temperatures continue to rise this century, we will keep setting more record highs."

The study team focused on weather stations that have been operating since 1950. They found that the ratio of record daily high to record daily low temperatures slightly exceeded one to one in the 1950s, dipped below that level in the 1960s and 1970s, and has risen since the 1980s. The results reflect changes in U.S. average temperatures, which rose in the 1950s, stabilized in the 1960s, and then began a warming trend in the late 1970s.

Even in the first nine months of this year, when the United States cooled somewhat after a string of unusually warm years, the ratio of record daily high to record daily low temperatures was more than three to two. Despite the increasing number of record highs, there will still be occasional periods of record cold, Meehl notes.

"One of the messages of this study is, you still get cold days," Meehl says. "Winter still comes. Even in a much warmer climate, we're setting record low minimum temperatures on a few days each year. But, the odds are shifting, so there's a much better chance of daily record highs instead of lows."

The study team analyzed several million daily high and low temperature readings taken over the span of six decades at about 1,800 weather stations across the country, thereby ensuring ample data for statistically significant results. The readings, collected at the National Oceanic and Atmospheric Administration's National Climatic Data Center, undergo a quality control process at the data center that looks for such potential problems as missing data, as well as inconsistent readings caused by changes in thermometers, station locations or other factors.

Meehl and his colleagues then used temperature simulations from the Community Climate System Model to compute daily record highs and lows under current and future atmospheric concentrations of greenhouse gases.

To Play With Giants, App Devs Risk Getting Squashed


Hot-selling mobile apps have earned some independent programmers hundreds of thousands of dollars. But one of the greatest risks of developing apps for a platform controlled by a large corporation, such as Google or Apple, is that you can easily get crushed.

Take for example Mike Jacobs, a developer of software startup Hello, Chair. For nine months, his team of three has been working on an iPhone app called Appsaurus, which makes App Store recommendations based on the apps you already own. So it was very bad news for Hello, Chair when Apple in September introduced a free App Store recommendation tool called App Store Genius.

“That’s one of the scariest things: If Apple moves an inch, they crush a bunch of little developers,” Jacobs said in a phone interview.

With giants dominating Silicon Valley, start-ups and independent programmers are fitting in between the cracks by developing apps for corporations’ mobile platforms. Apple’s App Store, which launched July 2008, is the largest to date with 100,000 apps and counting. Google’s Android platform is second largest, serving roughly 14,000 apps. In the case of the App Store, a lucky bunch have struck it rich with soaring sales, while others have suffered at the mercy of the giant they’re developing for.

More often, Apple is scrutinized for its questionable approval policy. The company has rejected some developers’ apps for unclear reasons, which often puts them in financial hurt (in severe cases, a six-digit loss).

But stories like Hello, Chair’s — where the corporation inadvertently competes with its developers — are a bit rare. Jacobs said his company was striving to provide something the iPhone was missing in hopes to make the platform even better. However, Apple, too, is thinking of ways to improve its products — and with a considerably larger team of in-house programmers and billions of dollars in resources, the Cupertino, California company beat a small start-up to the idea of an App Store recommendation tool.

Hello, Chair submitted Appsaurus to Apple this week and nervously awaits Apple’s approval. The team is hoping it does not face the same outcome as Podcaster, an app Apple rejected in September 2008. The Podcaster app enabled the iPhone to download podcasts and listen to them on the fly. Apple rejected Podcaster, saying it “duplicates the functionality” of the iPod. However, the iPhone didn’t have this feature when Podcaster was submitted. Only after rejecting Podcaster did Apple introduce a podcast downloader through its iTunes app.

Alex Sokirynsky, who developed Podcaster, said he had spent four months learning the iPhone’s programming language, and he was “heartbroken” by Apple’s rejection of Podcaster.

“Apple has a very tight hold on everyone in the App Store,” Sokirynsky told Wired.com. “They could pull any app for any reason, and the developer has no say. This could ruin a new company.”

This Goliath-stomps-on-David scenario isn’t unique to Apple, either. Etienne Baratte, a software engineer, was developing an app for the Google Android platform called Jamdroid, which would provide real-time traffic information anywhere on the globe. Baratte entered Jamdroid in Google’s Android Developer Challenge, a contest inviting developers to submit app prototypes for a chance to win awards. Jamdroid received an honorable score in the competition — but Google in August 2009 announced it was working on almost the exact same traffic-analysis tool.

Baratte was dismayed: He’d been working on Jamdroid since November 2007 with a few partners. He killed his project when Google rolled out its traffic service in August.

“There’s no competition possible at all,” Baratte said in a phone interview. “I can’t say they stole my idea. They’re in their right to implement such a service, and in fact, in a way I am quite happy that they did so…. But I spent all my free time on this.”

Hello, Chair hasn’t given up on Appsaurus, however. When Apple introduced App Store Genius, Jacobs and his team proceeded to add more features to Appsaurus to make it better than Apple’s recommendation system. When making recommendations, App Store Genius only takes into account the apps currently installed on a user’s iPhone. Appsaurus, Jacobs said, will use an interactive algorithm that allows users to rate and modify suggestions in real-time. The app will also make app recommendations based on other apps people have purchased, similar to Amazon’s “Customers Who Bought This Item Also Bought” feature.

Obama under fire on trade as Asia-Pacific leaders meet

US President Barack Obama has come under fire from Asia-Pacific leaders for backsliding on free trade at a regional summit devoted to driving the world economy out of crisis.

"President Obama is facing severe political constraints that run counter to free trade," Mexican President Felipe Calderon said, complaining about US foot-dragging on full implementation of the NAFTA pact for North America.

"The cruel paradox is that within a global economy, what really kills companies is inefficiency and lack of competition. Therefore protectionism is killing North American companies," he said in a speech in Singapore on Saturday.

"So I think this has to do with the fact that the US government is under strong political pressure that really is not being counteracted from the political perspective" of the Obama administration.

The US Congress has turned even more sour on free trade after the worst economic crisis since World War II.

One landmark pact with South Korea is languishing and critics say the White House has done little to revive it.

The US economy is picking up but unemployment has breached 10 per cent and economic leaders, including the heads of the International Monetary Fund and World Bank, warned in Singapore that protectionism could choke off recovery.

Russian President Dmitry Medvedev said controversial tariffs enacted by his government to shore up ailing industries were temporary and urged his regional colleagues to "do anything we can to refrain from protectionism in any sphere".

The warnings came as a two-day summit of the Asia-Pacific Economic Co-operation (APEC) forum began on Saturday.

Obama arrived later in Singapore to join the 20 other leaders, after a visit to Tokyo.

In a speech in the Japanese capital, Obama reaffirmed a US commitment to finally concluding the World Trade Organisation's Doha round of talks - a long-running bid to tear down barriers to global commerce.

And he said the United States was interested in an obscure trade pact that leaders say could become the nucleus for a massive trans-Pacific free-trade zone covering 2.6 billion people.

"The United States will also be engaging with the Trans-Pacific Partnership (TPP) countries with the goal of shaping a regional agreement that will have broad-based membership and the high standards worthy of a 21st century trade agreement," he said.

The TPP now involves Brunei, Chile, New Zealand and Singapore.

Australia, Peru and Vietnam have expressed interest in joining, and Obama's remarks were the clearest so far about Washington's plans.

"The US announcement is a significant statement of its intent to the Asia-Pacific region," Australian Trade Minister Simon Crean said.

"Importantly, it provides the critical mass essential for this initiative to go forward."

Obama meanwhile called for "balanced and sustained" growth around the world in the post-crisis phase, pressing Asian exporters including China to wean themselves off US consumers and build up their own demand.

His comments underlined a central theme of the APEC summit - that the world economy must be rebalanced so that voracious US consumerism is no longer the sole cylinder firing global growth.

Officials said the realignment was a main item of summit discussion prior to an evening dinner, when the leaders continued an APEC tradition by donning specially designed shirts reflecting the host nation's culture.
