Astronomers are puzzled by a strange bright spot which has appeared in the clouds of Venus. The spot was first identified by an amateur astronomer on 19 July and was later confirmed by the European Space Agency's Venus Express spacecraft.

NASA's Cassini spacecraft is now a nearly a year into its extended mission, called Cassini Equinox (after its initial 4-year mission ended in June, 2008). The spacecraft continues to operate in good health, returning amazing images of Saturn, its ring system and moons, and providing new information and science on a regular basis.

Saturn's tiny, icy moon Enceladus has recently been visited by NASA's Cassini orbiter on several very close approaches - once coming within a mere 25 kilometers (15 miles) of the surface. Scientists are learning a great deal about this curious little moon. Only about 500 kilometers wide (310 miles), it is very active, emitting internal heat, churning its surface, and - through cryovolcanism - ejecting masses of microscopic ice particles into Saturnian orbit.

Scientists say they have developed a quick technique for detecting liquids that could be used as explosives.

"Greetings citizen scientists, budding biohackers, and backyard explorers! We think you'll find the Make: Science Room a fun and useful resource. We hope you'll use it as your DIY science classroom, virtual laboratory, and a place to share your projects, hacks, and laboratory tips with other amateur scientists. Your Make: Science Room host is Robert Bruce Thompson, author of Illustrated Guide to Home Chemistry Experiments: All Lab, No Lecture. (Make: Books, 2008) and Illustrated Guide to Forensics Investigations: Uncover Evidence in Your Home, Lab, or Basement (not yet published). We'll be drawing material from these titles first, but will soon branch out into biology, astrononmy, Earth sciences, and other disciplines."

In September this year, two research groups independently reported the existence of monopoles - "particles" which carry an overall magnetic charge. But they exist only in the spin ice crystals. These crystals are made up of pyramids of charged atoms, or ions, arranged in such a way that when cooled to exceptionally low temperatures, the materials show tiny, discrete packets of magnetic charge.

"Researchers are finding that food miles are far from the whole story when assessing the environmental impact of what we eat. At a conference last month on the economics of food, Chris Foster of Manchester Business School presented some startling conclusions from a review of the evidence. "
