Self-Igniting Fungi Promising for Biomass-Based Fuels

The complete genetic makeup of two heat-loving fungi often found in composts that self-ignite without flame or spark has been decoded by an international team of scientists. Their findings may lead to the faster and greener development of biomass-based fuels, chemicals, and other industrial materials.

Will consumers accept the growing mobile payment options?

This week's Question: Google Wallet, an Android mobile app launched earlier this month, is slowly being rolled out to the public. The application allows users to make purchases with their phones. The technology uses near field communication (NFC) chips to store and remit credit card data, discount card information, and coupons. Users must enter a four-digit security PIN on their phones before making a purchase; they then tap their phone on a store's terminal, transferring the payment from shopper to retailer. Supporters appreciate the ease of use, while skeptics still have mobile device security concerns. What do you think? Will consumers accept the growing mobile payment options?

Cheap Sugars for Sustainable Biofuel Production

Researchers at Iowa State University think that fast pyrolysis - quickly heating biomass such as corn stalks or wood chips without oxygen to produce liquid or gas products - could be a new way to make inexpensive sugars from biomass.

Do you think light speed can be exceeded?

This week's Question: The European Organization for Nuclear Research, or CERN, reported that a neutrino beam fired from a particle accelerator near Geneva to a lab 454 miles away in Italy traveled 60 nanoseconds faster than the speed of light — a claim that potentially questions Einstein's 1905 special theory of relativity. Some physicists say neutrinos theoretically can travel at different speeds depending on how much energy they have, and mysterious particles, whose existence is still only theorized, can move with similar speeds. Other physicists, however, say that the CERN findings are the result of measurement errors since tracking neutrinos is very difficult. What do you think? Do you think light speed can be exceeded?

Flexible CIGS Solar Cells - 18.7% World Record Efficiency

New technology yielding flexible solar cells was developed by scientists at Empa, the Swiss Federal Laboratories for Materials Science and Technology. Key to the breakthrough is the control of the energy band gap grading in the copper indium gallium (di)selenide semiconductor, or CIGS, the layer that absorbs light and converts it into electricity.

Will we set foot on Mars?

  This week's Question: NASA recently unveiled its new "Space Launch System," which will be designed to carry the Orion Multi-Purpose Crew Vehicle, as well as important cargo, equipment, and science experiments to Earth's orbit and destinations beyond. "Tomorrow's explorers will now dream of one day walking on Mars," said NASA Administrator Charles Bolden. NASA's rovers, too, continue to learn more about the makeup of the planet. What do you think? Will we set foot on Mars?
