What is Taking Algae Biofuels So Long?
Producing biofuels from algae is a concept dating back to the oil shocks of the 1970s. At the time, the US Government created an algae research program which analyzed the thousands of strains of algae in hope of offsetting the shortage of fossil fuels. In 1996, the Department of Energy shut down the program, concluding…

Australian Carbon Trading Scheme Commences: All Emissions Are Not Local
Australian carbon trading took another step forward last month when the first carbon credits under the Carbon Pollution Reduction Scheme were issued. The national carbon trading program has been in the works for six years, politically supported by a Labor-Green coalition government; the first three to five years of the program will see a government-fixed…

Lunar Wind and Water
The solar wind is a stream of charged particles ejected from the upper atmosphere of the Sun. It mostly consists of electrons and protons with energies usually between 1.5 and 10 keV. The stream of particles varies in temperature and speed over time. These particles can escape the Sun’s gravity because of their high kinetic…

Fall Colors and the natural Carbon Cycle
As Fall turns leaves to colorful displays, starting in northern New England, and moving ever southward as Fall progresses, we think of the approaching Winter. We might also think of all the carbon that the once green leaves contain that will be released to the atmosphere as they decay. In the springtime, leaves soak up…

Turning Trash into Art
When you think of the words “garbage dump,” the first thoughts or images that spring forth from your mind probably aren’t related to art. But if you were to visit the Recology collection center in San Francisco, you would be seeing—and thinking about—trash in a whole new way. What you would witness is not only…

A Strange Martian Rock
A rock is a rock. Unless it is Martian. The first Martian rock NASA’s Curiosity rover has reached out to touch presents a more varied composition than expected from previous missions. The rock also resembles some unusual rocks from Earth’s interior. The rover team used two instruments on Curiosity to study the chemical makeup of…

Increased Rainfall Causes Drop in Sea Level?
Current perception of climate change leads us to believe that sea levels are constantly rising due to thermal expansion and melting ice caps. However, from the beginning of 2010 until mid-2011, the average level of the world’s oceans dropped by 0.2 inches. According to a recent study in the journal Geophysical Research Letters, this sea…

Banana fibre can fix marine oil spills, says study
Fibre from the stem of the banana plant can efficiently absorb oil spills that pollute coasts and threaten marine life says a new study by Indian researchers. Banana fibre, when treated with certain chemicals, can absorb up to 18 times their weight of oil, according to the study published last month (16 September) in the…
