- Broadcom MASTERS is the premier middle school science and engineering competition. Several 2014 finalists showed a flair for biomedicine. These young researchers tackled everything from diagnosing cancer early to alerting drowsy drivers before they fall asleep at the wheel.
- Tiny chemical droplets in a liquid sandwiched between panes of glass turn cloudy when they warm up. This will block some sunlight and potentially save on air conditioning bills.
- As sea levels rise, many cities will begin to experience frequent and extensive flooding at high tides. In some areas — even Washington, D.C. — such flooding could become a weekly headache.
- Forty teen researchers have been selected to compete in the Intel Science Talent Search. The event — a program of Society for Science & the Public — will take place in Washington, D.C., March 5 to11.
- The arrangement of major muscles in a duck-billed dinosaur’s legs would have helped them outrun predators such as T. rex, a new analysis suggests.
- New analyses of insects and mammals trapped in the La Brea Tar Pits point to climate surprises during the last ice age.
- Placing wind turbines high in the sky could let them harvest power from the faster, more reliable winds found at altitude.
- A stegosaur’s bony ‘armor’ didn’t just fend off a predator’s teeth. The tail spikes could gore attackers, ultimately killing them, fossils now show.
- Holly Jackson, 14, of San Jose, Calif., grabs top honors — and a $25,000 award — in the finals of the Broadcom MASTERS competition.
- Pre-teen’s invention clips onto a blind person’s cane and detects objects in a person’s path, helping them to avoid trip hazards.
