If growing vegetables in a box with no soil and out of direct sunlight sounds a little fishy, well, it is. Aquaponics is a relatively new way of intensified farming that combines aquaculture and hydroponics, according to a vegetable specialist.
Researchers have created a cellular probe that combines a tarantula toxin with a fluorescent compound to help scientists observe electrical activity in neurons and other cells. The probe binds to a voltage-activated potassium ion channel subtype, lighting up when the channel is turned off and dimming when it is activated.
Engineers have built and tested an earthquake-resistant house that stayed staunchly upright even as it shook at three times the intensity of the destructive 1989 Loma Prieta temblor 25 years ago.

Scientists have found evidence for a huge mountain range that sustained an explosion of life on Earth 600 million years ago. The mountain range was similar in scale to the Himalayas and spanned at least 2,500 kilometers of modern west Africa and northeast Brazil, which at that time were part of the supercontinent Gondwana.
West African chimpanzees will search far and wide to find Alchornea hirtella, a spindly shrub whose straight shoots provide the ideal tools to hunt aggressive army ants in an ingenious fashion. The plant provides the animals with two different types of tool, a thicker shoot for digging and a more slender tool for dipping.
A researcher has been studying prosthetics for a decade and is part of a group working to develop a sensor to tell how a limb changes, along with a system that automatically accommodates those changes. After additional testing and refinements, he hopes to find a company that wants to market the sensor system.
A plot has been discovered, apparently spread across Russia, India and China, whereby cash machines can be turned into a free money vending machine. The hack requires re-starting the cash machine– essentially a Windows terminal– from a prepared CD that injects malware into the system to circumvent the security.
Highlighting unexpected similarities between what animals do and what people are trying to do is a new strategy researchers are using to hopefully increase public awareness about animals and encourage conservation. They’ve created an iPhone app based on biologically inspired design, highlighting two dozen species that have helped engineers solve problems or invent new solutions.

A long-sought goal of creating particles that can emit a colorful fluorescent glow in a biological environment, and that could be precisely manipulated into position within living cells, has been achieved by a team of researchers.
Researchers have developed a new app enabling users to operate their smartphone with gestures. This development expands the range of potential interactions with such devices.
A team of English researchers recently returned from Iceland where, thanks to a bit of luck, they gathered the most extensive dataset ever from a volcanic eruption, which will likely yield considerable new insights into how molten rock moves underground, and whether or not a volcano will erupt.
For hundreds of years biologists have studied cells through the lens of a microscope. With a little help from a team of engineers, scientists could soon be donning 3-D glasses in a home theater-like lab to take their own fantastic voyage into the petri dish.
Engineers and computer scientists have developed a method that predicts the pattern of coils and tangles that a cable may form when deployed onto a rigid surface. The research combined laboratory experiments with custom-designed cables, computer-graphics technology used to animate hair in movies and theoretical analyses.
