Wow, 100 blog posts in 100 days … this has been big fun! I started this intense blogging effort in late January, when the economic slow-down made an acute showing in media outlets. I wasn’t getting paid assignments for a while, and I found myself without a regular outlet for what I love to do most: write about science. So I decided to utilize my own website! Through blogging, I’ve learned a lot about this fascinating realm called the blogosphere and explored social media outlets like Twitter. Every day, I’ve gotten to indulge my nerdy love of all sorts of science. Because I was so actively seeking story ideas, I ended up being able to propose more stories to my paying outlets (most of which have now rebounded significantly from the lull), and I even broke into a couple of new outlets, including Universe Today and Scientific American.
A lot of people have asked me what happens after the “100 Days.” The fact is, I really like blogging. I’ll continue to do it, but not every day. And certainly not on the weekends, when nobody’s reading! The blog’s new name will be unveiled after a brief break, while I enjoy the rest of my road trip with my dad to see my two brothers (right now we’re with the one in Florida).
I might not post another entry until Thursday …
Or maybe I will, and you just won’t see it.
Why? Because maybe I’ll see about borrowing this new invisibility cloak, that’s been created by researchers with Berkeley Lab and the University of California (UC) Berkeley.
Seriously! Xiang Zhang, a principal investigator with Berkeley Lab’s Materials Sciences Division and director of UC Berkeley’s Nano-scale Science and Engineering Center, has created a “carpet cloak” from nanostructured silicon that conceals the presence of objects placed under it.
The rest of this post, Day 100 of “100 Days of Science,” will be about the amazing work of Zhang’s team, which takes me back to the days of The Invisible Man by H.G. Wells and a fifth grade teacher, who once said anything man can imagine, we will eventually be able to do.

Carbon dioxide, of course, isn’t the only gas we emit into the atmosphere. Methane, a highly effective greenhouse gas, belches from landfills. And about five percent of our gas emissions comprise mercury.
We get it back: About 90 percent of human methylmercury exposure comes from ocean fish and shellfish — about 40 percent of that from tuna, a predator high in the ocean food chain.
A new study by the U.S. Geological Survey has confirmed a fascinating (if a bit ominous) mercury cycle that connects the atmospheric source to our dinner tables.

We know we have the technology to inject carbon dioxide into the ground. Oil and gas companies have been doing it for years, as a way to push the goods to the surface.
But can we make it stay there, as a way to keep it out of the atmosphere?That’s the multi-million-dollar question.
Carbon sequestration research got a boost this week when President Obama, speaking to the National Academy of Sciences, announced major funding for 46 Energy Frontier Research Centers across the country, which will build on existing institutions working on the gamut of carbon-alternative energy solutions.
“In no area will innovation be more important than in the development of new technologies to produce, use, and save energy,” Obama said, noting that “our future on this planet depends upon our willingness to address the challenge posed by carbon pollution.”
One of the funded programs is the Center for Nanoscale Control of Geologic CO2, at the Department of Energy’s Lawrence Berkeley National Laboratory in California. The project numbers among several sprouting up across the West, part of a gathering tide of fledgling carbon sequestration tests.

If you’re a person who loves the American West, you’ve probably had the impulse to just go get lost in it.
I mean, for a long time.
As in: forget the job, and any notions of a home or marriage … just walk, across deserts and through dusty Indian towns, down into canyons, to the tops of ridges where painted desert views lead to horizons sporting tiny bluish mountain ranges, shimmering like little mirages in the distance.
If you’re a person who loves the American West and is given to such impulses, you’ve no doubt heard of Everett Ruess, because he did that, more or less — until he disappeared.
Ruess, a 20-year-old artist and writer, wandered the Southwest in the early 1930s on a burro. For 75 years, no one has known what became of him. His legacy has traveled as a folk story through generations of backpack adventurers, passed along over campfires and between adventure-loving friends in reverent tones. Many people, like me, have toted the paperback about the mystery on their own backpacking trips.
Mystery solved.

A major research collaboration unmasked Mercury today, revealing more than people have ever known about the closest planet to the Sun.
NASA’s MErcury Surface, Space ENvironment, GEochemistry, and Ranging (MESSENGER) spacecraft flew by Mercury last fall, and researchers have been mining its data and images to fill in maps for nearly half the planet that were previously blank.
The new data also reveal a history of volcanoes that makes Mercury more like Mars than the Moon, and a modern surface that contains some very familiar materials — magnesium, for one, and possibly iron and titanium.
The findings were unveiled in a press conference today and appear in four separate papers in the journal Science.
This new image was compiled from the views of several cameras aboard the mission, in different wavelengths, as it departed Mercury.
Impact craters blasted recently by asteroids, such as the yellow crater called Kuiper near the center, have contrasting ejecta and rays because they excavated fresh material. Kuiper is 38 miles (62 km) across.
Other impact craters, such as those with ejecta that appear blue, have color contrasts because they excavated material from below the planet’s surface.
Lermontov crater, 94 miles or 152 km across, near the top left, appears orange and is thought to contain pyroclastic deposits from explosive past volcanic activity.
And then, there’s Rembrandt.
