In the early to mid-1900s, the islands of Hawaii were a far-away, exotic destination. People who managed to get there often kept mementos of that journey including kitschy menus from Hawaiian fine dining restaurants and hotels like like Trader Vic's and Prince Kuhio's.

Now these old menus are serving a purpose beyond colorful relics from the past. Kyle Van Houtan, an ecologist with the National Oceanic and Atmospheric Administration, says he's found a scientific purpose for the menus.

Why Aren't More Girls Attracted To Physics?

Originally published on Wed February 19, 2014 9:05 pm

Girls are more likely to take high school physics if they see women in their communities working in science, technology, engineering and math, a new study finds.

You don't need to be a social scientist to know there is a gender diversity problem in technology. The tech industry in Silicon Valley and across the nation is overwhelmingly male-dominated.

A viable, effective vaccine against malaria has long eluded scientists. Results from a preliminary study have ignited hope that a new type of vaccine could change that.

The experimental vaccine offered strong protection against malaria when given at high doses, scientists report Thursday in the journal Science.

The study was extremely small and short-term. And the candidate vaccine still has a long way to go before it could be used in the developing world.

Swinging CO2 Levels Show The Earth Is 'Breathing' More Deeply

Originally published on Thu August 8, 2013 9:34 pm

Plants accumulate carbon in the spring and summer, and they release it back into the atmosphere in the fall in winter. And a change in the landscape of the Arctic tundra, seen here, means that shrubs hold onto snow better, which keeps the organic-rich soils warmer and more likely to release carbon dioxide that's stored there.

Plant life on our planet soaks up a fair amount of the carbon dioxide that pours out of our tailpipes and smokestacks. Plants take it up during the summer and return some of it to the air in the winter. And a new study shows that those "breaths" have gotten deeper over the past 50 years.

This isn't just a curiosity. Plant life is helping to reduce the speed at which carbon dioxide is building up in our atmosphere. That's slowing the global warming, at least marginally, so scientists are eager to understand how this process works. The new study provides some clues.

A U.S. radar system that tracks thousands of objects orbiting Earth — from satellites to harmful debris — has been slated for shutdown, according to the Space News site. The ground-based network known as the "Space Fence" may cease to operate in October.

Can Chocolate Boost Brain Health? Don't Binge Just Yet

Wouldn't it be grand (and delicious) if we could boost our brain power with a daily dose of chocolate?

At first blush, a study published in the journal Neurology this week appears to offer tantalizing evidence that this may be the case, at least when it comes to seniors.
