How to Make a Golden Record

Sep 16, 2016

More than 300 million tourists visited US national parks in 2015, a 5 percent increase from the previous year. The National Park Service celebrated its 100th birthday last month, and recently President Barack Obama added to the list of protected parks and monuments.

But with increased popularity comes controversy and management problems.

At the Grand Canyon, for example, more visitors has resulted in more interest in development around the park — and more difficulty balancing preservation and tourism.

If other animals can regenerate their limbs, why can’t humans?

Sep 11, 2016

Have you ever watched a fish swim and thought that all of the long, tiny bones in its pectoral fin looked a bit — just a little bit — like fingers? Or seen a salamander that’s regrown its tail after a close call with a predator, and wondered why we can’t regenerate our limbs? As scientists learn more about the genes that shape animal musculoskeletal systems, they’re uncovering clues about how our own limbs developed — and may someday regenerate.

How much math should kids learn in school?

Did you use a polynomial equation today? When was the last time you calculated the volume of a sphere?

While human achievements in mathematics continue to reach new levels of complexity, many of us who aren’t mathematicians at heart (or engineers by trade) may struggle to remember the last time we used calculus.

It’s a fact not lost on American educators, who amid rising math failure rates are debating how math can better meet the real-life needs of students. Should we change the way math is taught in schools, or eliminate some courses entirely?

US officials are rushing to develop a Zika vaccine by 2017

Sep 10, 2016

The Rio Olympics have come and gone, but the spread of Zika virus internationally remains a threat for the United States. The CDC is actively monitoring two clusters of the virus in Florida. Government officials expect that Zika will eventually spread. Meanwhile, vaccine candidates are being rushed through clinical trials, but won't be available at least until the spring of 2017. 

Anthony Fauci, director of the National Institute of Allergy and Infectious Diseases, says that for now, it’s important to contain Zika and to raise public awareness about its effects.

Fans of the show "Mr. Robot" know that cybersecurity programmer Elliot Alderson is no character to mess with. As a member of the cyber-vigilante group "fsociety," Elliot is dedicated to bringing down E Corp, the company responsible for his father’s death, through technological sleights of hand. Elliot’s hacks have made use of Raspberry Pi computers, DeepSounds discs, and DDoS attacks, and recently even targeted the FBI.
