Counting Bugs In Panama? Get Out Your Tree Raft

Arachnoscelis magnifica

Originally published on Mon January 7, 2013 3:22 pm

There are more species of insects than pretty much anything else in the world. And scientists know there are millions they haven't even identified yet. Now, in a tropical rainforest in Panama, a multinational team of scientists has just completed the first ever insect census.

Scott Miller, an entomologist at the Smithsonian who worked on the Panama, shows off one of the species from the survey that's at the National Museum of Natural History's insect zoo in Washington, D.C.

Gravity Never Sleeps, And Other Lessons Nations Learn From Space Programs

This picture received from North Korea's official Korean Central News Agency on Wednesday shows an orbit image of the satellite Kwangmyongsong-3, being monitored on a large screen at a satellite control center in Cholsan county, North Pyongan province in North Korea.

Sputnik 1 just beeped. China's first satellite, launched more than a decade later, simply radioed a communist anthem back to Earth. So far, North Korea's first satellite appears to be less accomplished.

And that shouldn't be a surprise.

Given the history of first orbital space shots, North Korea's apparent struggle with its mission is fairly typical, says David Akin, an associate professor of aerospace engineering at the University of Maryland.

Ah, Wilderness! Nature Hike Could Unlock Your Imagination

Want to be more creative? Drop that iPad and head to the great outdoors.

That's the word from David Strayer, a cognitive neuroscientist who studies multitasking at the University of Utah. He knew that every time he went into the southern Utah desert, far from cellular service, he started to think more clearly.

But he wanted to know if others had the same experience.

Land Creatures Might Not Have Come From The Sea

The fossil remains of Dickinsonia, an Ediacaran organism that's long been extinct. Scientists have long assumed these early life forms lived in the sea, but a new study argues they emerged on land.

Cartoonists have found many clever ways to depict the conventional wisdom that complex life evolved in the sea and then crawled up onto land. But a provocative new study suggests that the procession might be drawn in the wrong direction. The earliest large life forms may have appeared on land long before the oceans filled with creatures that swam and crawled and burrowed in the mud.

Forget Extinct: The Brontosaurus Never Even Existed

This photograph from 1934 shows the Carnegie Museum's Apatosaurus skeleton on the right — wearing the wrong skull.

It may have something to do with all those Brontosaurus burgers everyone's favorite modern stone-age family ate, but when you think of a giant dinosaur with a tiny head and long, swooping tail, the Brontosaurus is probably what you're seeing in your mind.

Well hold on: Scientifically speaking, there's no such thing as a Brontosaurus.

Even if you knew that, you may not know how the fictional dinosaur came to star in the prehistoric landscape of popular imagination for so long.

The Next Workplace? Behind The Wheel

Brad Hines is a building contractor in Los Angeles who spends a good eight hours a day in his 2008 Dodge Ram. He talked to us from his truck — hands-free, of course.

"I do everything in my truck. I drive from job site to job site. I take calls. I try to get on the computer and clean up daily reports. I answer emails on my phone. I use my truck as a mobile office," Hines says.

The idea of the mobile office is far from new — Willy Loman; the Avon Lady; plumbers; electricians. Now, technology is taking the idea of working from the road to a whole new level.

Ask A NASA Astrobiologist About Dec. 21 'Doomsday'

On Dec. 21, 2012, some fear that a rogue planet will collide with Earth and destroy the planet, or that the supposed end of the Mayan calendar will lead to the obliteration of the universe.

When people have questions about these scenarios, they often turn to the Internet.

NASA astrobiologist David Morrison has taken it upon himself to enter that online conversation and answer hundreds of questions about the science of existential threats.

Have you ever wondered whether music conductors actually influence their orchestras?

They seem important. After all, they're standing in the middle of the stage and waving their hands. But the musicians all have scores before them that tell them what to play. If you took the conductor away, could the orchestra manage on its own?

Experiments That Keep Going And Going And Going

William Beal, standing at center, started a long-term study on seed germination in 1879. He buried 20 bottles with seeds in them for later researchers to unearth and plant.

A biologist who has been watching a dozen bottles of bacteria evolve for nearly a quarter of a century is hoping he can find someone to keep his lab experiment going long after he dies.

Meanwhile, just by coincidence, a botanist who works across campus is carefully tending an experiment that started before he was born, all the way back in 1879.

These two researchers, both at Michigan State University in East Lansing, represent different sides of an unusual phenomenon in science: experiments that outlive the people who started them.

Scientists working on NASA's six-wheeled rover on Mars have a problem. But it's a good problem.

They have some exciting new results from one of the rover's instruments. On the one hand, they'd like to tell everybody what they found, but on the other, they have to wait because they want to make sure their results are not just some fluke or error in their instrument.

A 'Green' Gold Rush? Calif. Firm Turns Trash To Gas

Energy Of The Future? California company Sierra Energy is testing out a reactor that turns garbage — like these wood chips, metal fragments and plastics — into synthetic gas that can then be turned into a low-carbon diesel fuel.

Second of a two-part series. Read Part 1

California starts the ball rolling Wednesday on a controversial scheme to keep the planet from overheating. Businesses will have to get a permit if they emit greenhouse gases.

Some permits will be auctioned today; the rest are free. The big idea here is the state is putting a ceiling on emissions.

It's a gamble. And for this top-down climate plan to work, it has to usher in a greener, more efficient economy.

The same brain system that controls our muscles also helps us remember music, scientists say.

When we listen to a new musical phrase, it is the brain's motor system — not areas involved in hearing — that helps us remember what we've heard, researchers reported at the Society for Neuroscience meeting in New Orleans last month.

Hurricane CSI: Frankenstorm Sandy And Climate Change

It was not a good year for people, weather and climate. The winter was strangely warm in many places and the summer ridiculously hot. As a large fraction of the country suffered through extreme or even extraordinary drought many folks naturally wondered, "Is this climate change?" Then along came a presidential election in which the words "climate change" disappeared from the dialogue. Now, just a week or so before voting day, the convergence of westbound Hurricane Sandy with a eastbound cold front is creating a massive storm, a Frankenstorm even, that is threatening millions of Americans.

See No Evil, Say No Evil. But As for Hearing? Hmmm

These are baby bats — embryos actually. They remind me of those See No Evil, Say No Evil, Hear No Evil monkey pictures I saw growing up, but these little guys are much, much cuter. And, of course, being bats, the hearing thing doesn't apply. Bats don't hear with our kind of ears, so of course, there's no covering-ears-up picture. That wouldn't make bat sense.

The researchers at Oregon Health & Science University in Portland say they took the step to try to prevent women from giving birth to babies with genetic diseases. But the research is raising a host of ethical, social and moral questions.
