Faster, cheaper biofuel production

A scanning electron microscope image of the diatom Thalassiosira pseudonana (credit: Scripps Institution of Oceanography at UC San Diego) Researchers at Scripps Institution of Oceanography at UC San Diego have developed a method for greatly enhancing biofuel production in tiny marine algae by genetically engineering a key growth component in biofuel. The researchers say a significant roadblock in algal […]

Bacterial evolution offers clues to tradeoffs in financial investments

Bacteria have the potential to teach valuable investment lessons (credit: University of Exeter) Scientists have found that bacteria have the potential to teach valuable investment lessons. The research, published in the journal Ecology Letters, takes advantage of the fact that bacteria, like humans, have limited resources and are constantly faced with investment decisions. Bacteria though are […]

Detecting DNA in space

Gene-sequencing chip can survive space radiation on Mars, MIT scientist finds Is there DNA on Mars? (credit: NASA) If there is life on Mars, it’s not too farfetched to believe that such Martian species may share genetic roots with life on Earth, based on RNA or DNA. That’s because more than 3.5 billion years ago, […]

Building 3D heart tissue with a programmable chip-making device

This image of shows multiple thin layers of an elastic “biorubber” polymer (purple) and interwoven muscle tissue (green) formed from neonatal rat heart cells (credit: MIT photo) By adapting a programmable device used to manufacture integrated circuits, MIT Draper Laboratory researchers have devised a semi-automated process to build three-dimensional heart tissue, MIT Technology Reviewreports. Tissue is […]

Scientists sequence genome of ‘sacred lotus,’ may hold anti-aging secrets

Nelumbo nucifera from China, more commonly known as the “sacred lotus” (credit: Jane Shen-Miller/UCLA) A team of 70 scientists from the U.S., China, Australia and Japan reports having sequenced and annotated more than 86 percent of the genome of the “sacred lotus,” which is believed to have a powerful genetic system that repairs genetic defects, and may […]

How to convert an iPhone into a handheld biosensor

University of Illinois researchers developed a cradle and app for the iPhone to make a handheld biosensor that uses the phone’s own camera and processing power to detect any kind of biological molecules or cells (credit: Brian T. Cunningham/University of Illinois) University of Illinois at Urbana-Champaign researchers have developed a cradle and app for the iPhone (Android version […]

Chinese project probes the genetics of genius

(Credit: iStockphoto) Researchers at BGI (formerly the Beijing Genomics Institute) in Shenzhen, China, the largest gene-sequencing facility in the world, are searching for the quirks of DNA that may contribute to genius in an ethically controversial study. They are scouring the genomes of 1,600 U.S. adolescents who signed up for the Study of Mathematically Precocious […]

3D-printed ‘bionic’ ear melds electronics and biology

Scientists used 3-D printing to merge tissue and an antenna capable of receiving radio signals (credit: Frank Wojciechowski) Scientists at Princeton University have used a 3D printer to create a functional ear that can “hear” radio frequencies up to microwave frequencies. The researchers’ primary purpose was to explore an efficient and versatile means to merge electronics with tissue. The […]
