Clayton Christensen is perhaps most famous for identifying the concept of a disruptive innovation – a new technology that introduces new markets and new ways that people interact with products. His latest offering, The Innovator’s DNA, co-authored by Jeff Dyer and Hal Gregersen, takes a look at what skills lead a person to innovation and creativity.

The current method for producing alcohol biofuels, in particular butanol, is through metabolic cellular processes. Clostridia species are used to produce butanol, but they are not very suitable because they are complex and not well understood. Biological pathways have also been developed for strains of Escherichia coli and Saccharomyces cerevisiae; both of these microbes have better genetic tools available.

At the ARPA-E 2012 summit recently held just outside Washington, DC, Bill Gates and DOE Secretary Steven Chu sat down and discussed the world's largest energy challenges in front of a large audience. Watch in the window on the right.

Are you applying for jobs that include a rotation program? No clue what a rotational program is? Think of it as a job sampler and a possible opportunity to travel. Rotational programs can also be a valuable way to familiarize yourself with a company and several positions.

"Make Your Profile Picture a Molecule Month" was an idea of David Monteiro, a chemical engineering student of Stevens Institute of Technology, and is intended to spread enthusiasm for chemistry and promote the expression of one's passion for the field.

Technically, a Pi Day song should never end, but that would crash YouTube. And probably bore most listeners. So the music video in the right hand window will get you started and then you can hum it as long as you want.

The results are in from the AIChE Pi Day Pie Bake-Off! Check out photos of the winning desserts.

Today, mathematicians and number-lovers celebrate Pi Day — because the date can be written as 3.14; extreme enthusiasts take pi to five decimal places and mark Pi Minute at 1:59 (3.14159).

Applications for stem cells seem endless. These versatile cells can be used to study development and disease, and they also have the ability to replace damaged cells and treat disease, to name a few of their uses. Recently, there is a new front on which stem cells have an important role: organ transplants.

Located in the hot, dry Spanish countryside near the village of Fuentes de Andalucia,Torresol Energy's Gemasolar commercial-scale concentrated solar power plant (CSP) achieved a global milestone last summer by using an innovative storage system – molten salt – to provide uninterrupted power for an entire day, sunrise to sunrise.

A new economic trend emerged during 2011. The United States actually began exporting more petroleum products than it imported for the first time since 1949.

We recently caught up with Amanda Robbens, vice chair of the Local Sections Committee and Virtual Local Section, to discuss the upcoming Local Section Leadership Workshop, which will take place before the Spring Meeting in Houston (more details below).

Miles C. Barr, who recently received his PhD in chemical engineering from MIT, has just been awarded the prestigious $30,000 Lemelson-MIT Student Prize for developing an innovative solar technology. His innovation is a new way to print solar cells directly onto a variety of surfaces, such as paper.

Pop recording artist Björk released Biophilia, a project devoted to exploring the world of biology. The single "Hollow" tells the story of DNA, Björk-style. NPR describes the video for "Hollow," which you can click to here.
