spacedesk_carina_moshbrown

The Hubble Space Telescope’s journey crossed the double-decade mark today, and our readers and followers are celebrating the beloved satellite with their desktops.

For the past five weeks, we’ve asked followers of @wiredscience on Twitter to change their computer backgrounds to some of our favorite Hubble images and send us a photo of their workstations.This week, we featured Hubble’s newest image, a spectacular shot of part of the Carina Nebula. Above is our favorite Space Desk this week, from @moshbrown, who may have gotten some extra credit for having Wired Science on the desktop as well.

We’ve collected some of the best shots here from the whole series on the following pages. If you need more Space Desk, we’ve included links to each weeks’ gallery of entries.

Bill Gates and Friends Make Case for Energy R&D

solyndra_0831

Bill Gates and a host of other corporate heavy hitters have founded a new organization to push for more research and development into clean energy technology.

Gates and former DuPont CEO Charles Holliday heralded the launch of the American Energy Innovation Council with an unusually clear and concise argument for increased government support for green tech R&D.

“Despite talk about the need for ’21st century’ energy sources, federal spending on clean energy research is also relatively small. The U.S. government annually spends less than $3 billion — compared with roughly $30 billion annually on health research and $80 billion on defense research and development,” they argued in The Washington Post.

The editorial goes on to lay out why energy technologies deserve government backing. First, they write, “There are profound public interests in having more energy options.” Second, the huge costs associated with developing new energy technologies requires government help. As they put it, “The nature of the energy business requires a public commitment.” And last, they point out that the cheapest electricity comes from the oldest plants, which makes for a conservative industry. “Power plants last 50 years or more, and they are very cheap to run once built, meaning there is little market for new models.”

Wow! Celebrate Hubble’s 20th With Best Space Image Ever

hubble-carina-20th-anniversary

We were already dreading the day Hubble dies, but this mind-blowing new image released to celebrate the space telescope’s 20th anniversary makes us wish for eternal life for the famous satellite even more.

This new gem rivals what may be Hubble’s most famous image, a shot of the Pillars of Creation taken in 1995. The shot above is of a star-forming region in the Carina Nebula. The enormous pillar of gas and dust is 3 light-years tall. The seam in the middle is the result of new stars forming and emitting powerful gas jets that are ripping the pillar apart.

Hubble’s capabilities are all the more impressive considering the rocky start the telescope suffered through when a defect was discovered in its primary mirror after it had been launched and began returning images that weren’t in focus. Scientists and engineers were able to fix the problem, and today Hubble is more capable than ever with its new Wide Field Camera 3, installed last year.

If you’ve read this far without making this image your computer desktop background, click here now. We’ve been celebrating Hubble on our desktops for the last month, by asking followers of @wiredscience on Twitter to send us a photo of their workstations with a different Hubble photo on their computer screens each week. So far we’ve featured the Black Eye Galaxy, the Eagle Nebula, Jupiter and the Cat’s Eye Nebula.

Send us a photo of your desk or office with the new Carina Nebula photo, on twitter or by e-mail, and we’ll tweet our favorite and include the best from all five weeks in a post on Wired Science later today.

Also, check out this interactive timeline of Hubble’s history, and the links below to more mind-blowing Hubble photos we’ve featured on Wired Science before.

Evolution’s New Foe: Timid School Administrators

origin

Evolution education is under attack in Weston, Connecticut, but not from the usual direction.

Nobody is promoting intelligent design in the curriculum, or asking schools to teach evolution’s “strengths and weaknesses.” There’s just an administration afraid that teaching third graders too much about Charles Darwin will cause trouble.

“They might have just been looking to avoid controversy, but that has the same effect,” said Steve Newton, programs and policy director at the National Center for Science Education. ” If you’re not looking to teach children the best science, that harms their education.”

At issue is a class section proposed in 2008 by Mark Tangarone, teacher of the third, fourth and fifth grade Talented and Gifted program at the Weston Intermediate School. Tangarone wanted his third graders to study and compare the accomplishments of Abraham Lincoln and Charles Darwin.

To learn about Darwin, students would have retraced the path of the HMS Beagle, the expedition that inspired a young Darwin’s theory of evolution. Each student would study a stop in the voyage, reporting on the animals and adaptations that Darwin observed.

When Tangarone ran his class plan by then-principal Mark Ribbens, he was denied.

The Nanometer Matterhorn

nanomatterhorn

Those crazy IBM research engineers, what will they create at the nanoscale next? To demonstrate a new material etching technique that could allow for ever smaller computer chip components to be made, they created a model of the Matterhorn that stands just 25 nanometers tall. That’s 17,912,000,000,000 times smaller than the 14, 691-foot real mountain. It is even 1.8 billion times smaller than the Disney’s Matterhorn ride.

The mini-mountain was created using scanning-probe lithography: a tiny, heated stylus carved the mountain into a film of glass 100 nanometers thick. The whole operation took 120 distinct steps. The research was reported in the journal Science Thursday.

It got us wondering. What are the best things that have ever been carved or etched at the nanoscale? The classic thing to do is write the letters of your company (IBM) or university (MIT). But stranger things abound like the nanobama tiny presidential portrait. Let us know if your lab has done something interesting. We’d love to publish your nanoart weirdness.

Sea Creatures Travel Far to Colonize After Volcanic Eruptions

ctenopelta_porifera_cmyk_crop

When volcanic eruptions wipe out life at hydrothermal vents, some of the new species that set up camp afterward may come from as far as 200 miles away.

“We don’t understand how they get from one vent to another,” said biological oceanographer Lauren Mullineaux of Woods Hole Oceanographic Institute. “But because we now see that they can move these long distances, it expands the scale of connectedness between different vents.”

Living at the intersection of tectonic plates, organisms that colonize hydrothermal vents are faced with some of the most extreme conditions on earth, including complete darkness and extreme chemicals spewing from the ocean floor. They can also be wiped out instantly by volcanic eruptions along the fault lines.

Sometime between late 2005 and January 2006, a set of these eruptions rocked 9 miles of the East Pacific Rise just south of Acapulco, Mexico.  The eruption paved over some of the area’s hydrothermal vent communities with lava. The vents, which are usually teeming with life, were destroyed as fully as a clear-cut forest covered over with concrete.

Six months later when Lauren Mullineaux and her team arrived at the ridge to study the organisms there, they were faced with a serendipitous natural experiment created by the eruption.

“This kind of opportunity rarely comes up,” said Mullineaux, co-author of the study published in the Proceedings of the National Academy of Sciences April 12. “The combination of this eruption happening and us being geared up to study it was really exciting. It put us in a really unique position to look for changes.”

Op-Ed: The DIY Genius of the Original Earth Day

fromthefields_bannerdocumerica-earth

I’ve come to believe that Earth Day is the least understood famous event in modern American history. Every April 22, we pay ritual homage to the planet. This year, the 40th anniversary of Earth Day, the hosannas are likely to be especially loud.  But few people appreciate what made Earth Day great. Even environmentalists have not learned the most important lesson of Earth Day 1970.

The first Earth Day was even bigger than the biggest civil rights march or antiwar demonstration or woman’s liberation protest in the 1960s.  Roughly 1,500 colleges and 10,000 schools held environmental teach-ins. Earth Day activities also took place in churches and temples, in city parks and in front of corporate and government buildings. Though the largest crowds gathered on April 22, many institutions and communities celebrated for a week, not just a day. Millions of Americans took part.

The original event ultimately was about do-it-yourself empowerment, not about education or protest or celebration. In the course of writing a history of Earth Day 1970, I’ve tracked down dozens of people who organized Earth Day events, and I’m impressed by how many still are involved in the environmental cause. They defend rivers, promote green building, administer environmental-protection agencies, host eco programs on radio and television and much more. Some already were environmentalists before Earth Day, but most were not. Earth Day helped to make the first green generation.

Earth Day was superb leadership training. Often, the local organizers worked for months to plan their events. They were tested repeatedly. What counted as an environmental issue? Was the goal to advance an agenda or to involve as many people as possible? Would the emphasis be on education, activism or media spectacle? What relationship would the Earth Day effort have to other social movements, if any? Should the program feature local speakers or outsiders? Were any sources of funding off limits? Almost every question was potentially divisive. Yet the experience of planning Earth Day gave thousands of people a chance to develop the skills, contacts and sense of mission that provided a foundation for future activism.

Earth Day grew out of a call for a national environmental teach-in by U.S. Senator Gaylord Nelson of Wisconsin, who was smart enough to let others take ownership of the event. To help promote the teach-in, Nelson hired a group of young activists led by Denis Hayes, and the Hayes group formed Environmental Action after Earth Day to continue to press for change.  But the essential organizing effort came at the grassroots. Tens of thousands of people organized Earth Day events, and the organizational effort transformed many of those involved. What these small, independent networks achieved is startling.

China Could Wipe Out Recycled Toilet Paper

toiletpaper

The paperless, global economy may have an unexpected downside for your backside: The reduction of high-quality white paper use may hurt the quality of the recycled toilet paper made from it.

Printer and copier paper retain the nice, long fibers that make the best recycled toilet paper. But a resurgent Chinese economy and domestic waste reduction efforts are cutting the available supply of the good stuff, said Jeff Phillips, executive vice president of operations at Seventh Generation, a major recycled toilet paper manufacturer.

“The cost of office waste paper has skyrocketed (more than doubled) in the last six months primarily as a result of China re-entering the market,” Phillips wrote in an e-mail to Wired.com. “There has [also] been a reduction in availability due to more offices trying to reduce paper consumption and through the use of electronic media.”

Waste paper is stuffed into cargo containers returning to China after dropping off manufactured goods on American shores. Once there, it’s usually recycled into different paper products.

The troubling trend for the domestic bath-tissue industry was highlighted in a recent report in a new report in Chemical & Engineering News.

“We want a recycled paper that has a certain quality,” Martin Wolf, director of product and environmental technology at Seventh Generation, told C&EN. “We look for the longest fiber possible for strength and absorbency, and as flexible a fiber as possible so toilet tissue is soft.”

In the hierarchy of raw material for toilet paper, virgin pulp is the best, followed by office paper, and then other materials like brown bags. But virgin pulp requires cutting down trees, so some companies and users have opted for the stuff made from office paper. Without good office paper, the already tough job of making soft recycled toilet paper will get even harder.

“The biggest challenge, especially for our toilet-paper products, is perceived softness,” Wolf said. “The North American consumer is quite accustomed to pretty soft paper, but there is only a certain amount of softness you can achieve with recycled fibers.”

The only hope, or so Chemical & Engineering News says, is better chemicals and coatings for the rough stuff.

Origin of Life Chicken-and-Egg Problem Solved

dna5a

A chicken-and-egg paradox at the foundations of life may finally be solved.

Scientists have wondered how the first simple, self-replicating chemicals could have formed complex, information-rich genetic structures, when replication was originally such an error-prone process. Every advance would soon be lost to copying errors.

According to a new study, the answer may lie in the fundamental nature of those chemicals. The errors may have triggered an automatic shutdown of replication. Such stalling would allow only error-free sequences to be completed, giving them a chance at evolving.

“A chemical system with this property would be able to propagate sequences long enough to have function,” wrote researchers led by Harvard University systems biologist Irene Chen. The study was published April 1 in the Journal of the American Chemical Society.

Treating Climate Change as a Curable Disease

stethoscope

Nearly 200 scientists from 14 countries met last month at the famed Asilomar retreat center outside Monterey, California, in a deliberate bid to make history. Their five-day meeting focused on setting up voluntary ground rules for research into cloud-brightening, giant algae blooms and other massive-scale interventions to cool the planet.

It’s unclear how significant the meeting will turn out to be, but the intent of its organizers was unmistakable: By choosing Asilomar, they hoped to summon the spirit of a groundbreaking meeting of biologists that took place on the same site in 1975. Back then, scientists with bushy sideburns and split collars — the forefathers of the molecular revolution, it turned out — established principles for the safe and ethical study of deadly pathogens.

climate_desk_bugThe planners of Asilomar II, as they called it, hoped to accomplish much the same for potentially dangerous experiments in geoengineering. Instead of devising new medical treatments for people, the scientists involved in planet-hacking research are after novel ways to treat the Earth.

The analogy of global warming to a curable disease was central to the discussions at the meeting. Climate scientist Steve Schneider of Stanford talked about administering “planetary methadone to get over our carbon addiction.” Others debated what “doses” of geoengineering would be necessary. Most crucially, the thinkers at Asilomar focused on the idea that medical ethics might provide a framework for balancing the risks and benefits of all this new research.
