Engineers have now hit upon a way to impart more dexterity to simple robotic grippers: using the environment as a helping hand. The team has developed a model that predicts the force with which a robotic gripper needs to push against various fixtures in the environment in order to adjust its grasp on an object.
New biosensors have been developed that could improve control and complexity of metabolically engineered microbes, bringing us one step closer to a future in which genetically engineered bacteria can produce valuable chemical commodities in an environmentally friendly way.
Solar-Active-Houses heat themselves using heat collectors and water tanks. However, no one had conducted an objective assessment of how efficiently they do so. Now researchers have put some of these solar houses to the test, and have identified where there was room for improvement and laid the scientific groundwork for this housing concept.

As the demand grows for ever smaller, smarter electronics, so does the demand for understanding materials’ behavior at ever smaller scales. Physicists are building a unique optical magnetometer to probe magnetism at the nano- and mesoscale.
By analyzing the natural mechanics of the water strider that enable it to launch off water's surface scientists have emulated this extreme form of locomotion in novel robotic insects.
Two key physical phenomena take place at the surfaces of materials: catalysis and wetting. A catalyst enhances the rate of chemical reactions; wetting refers to how liquids spread across a surface. Non-wetting surfaces promote chemical reaction rates, new research confirms.
Researchers report that they have designed a cheap prosthetic knee that mimics normal walking motion. The team reports that it has calculated the ideal torque that a prosthetic knee should produce, given the mass of the leg segments, in order to induce able-bodied kinematics, or normal walking.
Graphene has been called the miracle material but the single-atomic layer material is still seeking its place in the materials world. Now a method to make 'defective' graphene could provide the answer. Scientists now report that they have developed a simple electrochemical approach which allows defects to intentionally be created in the graphene, altering its electrical and mechanical properties and making the material even more useful.

Human hair structure has been studied extensively for more than 70 years, but a complete picture of its local structure has proven elusive. But now, by combining a submicron X-ray beam with cross-section geometry, a team of researchers has detected new structural features of human hair.
A phosphorus-based ligand facilitates palladium-catalyzed coupling of challenging building blocks, scientists report.
An organic dye that can light up cancer cells for two powerful imaging techniques providing complementary diagnostic information has been developed and successfully tested in mice, researchers report.
Researchers have developed a yarn from ordinary gelatine that has good qualities similar to those of merino wool fibers. Now they are working on making the yarn even more water resistant.
Semiconductor lasers are capable of emitting over the full visible color spectrum, which is necessary to produce a white laser, researchers have demonstrated. The technological advance puts lasers one step closer to being a mainstream light source and potential replacement or alternative to light emitting diodes (LEDs). Lasers are brighter, more energy efficient, and can potentially provide more accurate and vivid colors for displays like computer screens and televisions.
