Bringing down the trash

Bringing down the trash

The density of junk orbiting the Earth is at or near a critical value beyond which this man-made debris will self-perpetuate, forming many smaller pieces that are even more of a problem.I wrote this article for Physics World about the latest ideas about how to bring down [Read More]

Meat from scratch

Meat from scratch

  If all goes according to Mark Post’s plan, he will appear on television in October and devour a hamburger that costs about twice as much as most houses do in the United States. Yes, as Charlotte the spider might have written, that’s some burger. “It’s not [Read More]

Flipping Icebergs

Flipping Icebergs

Icebergs look like towering, frozen mountains that drift through water. Their peaks may soar hundreds of feet above the surface and large ones cover as much area as major cities. When one of these blocks of ice flips over, it causes a great splash. In recent experiments at [Read More]

Moon twinkles

Moon twinkles

If you ever travel to the moon, don’t forget to pack a heavy-duty umbrella. It’s not for downpours: With no atmosphere, there’s no chance of rain. But hundreds of times each year, small space rocks smash into the lunar surface, flashing brightly enough to be seen from [Read More]

Mapping the invisible

Mapping the invisible

Most maps show places you can visit and how to get there. Most maps, however, were not made by astronomers — physicists who study stars and galaxies far, far, far away. At a recent meeting in Texas, three teams of these scientists presented new maps unlike any atlas, [Read More]

Electronic skin

Electronic skin

  James Bond and his enemies would be interested in the goings-on at the laboratory of John Rogers. So would Batman, the Spy Kids, Darth Vader and their enemies. That’s because Rogers, a materials scientist at the University of Illinois at Urbana-Champaign, mixes [Read More]

Introducing silicene

Introducing silicene

Electronics engineers are constantly seeking the next great thing, the supermaterial that will allow for devices even smaller and faster than are possible with silicon chips. But research from this year has convinced some people that silicon’s successor may be none other [Read More]

Better boarding

Better boarding

Slow boarding annoyed Jason Steffen. but rather than complain about it, like most of us would, the Fermilab astrophysicist took to his computer and began writing algorithms to model potential solutions. In 2008 he announced a method that he claimed would cut boarding times [Read More]

Self-cleaning clothes

Self-cleaning clothes

Cleaning clothes usually requires soap and water to remove stains and smells, and a tumble in the dryer or an afternoon on the clothesline to dry. The time and energy needed to turn a heap of dirty laundry into a pile of clean clothes might make people wish for clothes that [Read More]

Searching for underground water, from the sky

Searching for underground water, from the sky

Keeping track of water makes for tricky science. It drains through soil, slips through cracks in rocks and refills underwater reserves. It bubbles up through springs and runs in rivers. Water evaporates and forms clouds; rain brings it back to earth, where it keeps plants [Read More]
