Video imaging of single molecule DNA replication

Almost all life is based on DNA being copied or replicated. Now for the first time, scientists have been able to watch the replication of a single DNA molecule, with some surprising findings. For one thing, there is a lot more randomness at work than has been thought.

New cellular imaging paves way for cancer treatment

Researchers at the Universities of York and Leiden have pioneered a technique that uses fluorescent imaging to track the actions of key enzymes in cancer, genetic disorders, and kidney disease. Scientists hope this new development will aid drug design for new anti-cancer, inflammation, and kidney disease treatments. It will also provide diagnostic tools for disease identification and allow medical professionals to measure the effectiveness of drug treatment regimes in an easy laboratory manner.

Nanotube Yarns Generate Electricity When Stretched

Scientists at The University of Texas at Dallas and South Korea’s Hanyang University have developed tiny, high-tech yarns that generate electricity when stretched or twisted. The nanoyarns, constructed from hollow carbon nanotubes, create current when coated with an ionically conducting material — even a simple mixture of table salt and water.

From Seawater to Drinking Water? Nanotubes Upgrade Desalination Efforts

Looking to nature for inspiration, scientists from Lawrence Livermore National Laboratory (LLNL) and Northeastern University have used carbon nanotubes to mimic the water-filtering proteins of the body. The super-thin graphene cylinders improve water desalination efforts and support a new generation of high-flux membranes.

Harmonic Air Motor Offers Very High Efficiency

Currently available air motors have many advantages over electric motors. They are more compact, lighter-weight, instantly reversible without sparking, create no heat buildup, are undamaged by stalling or overloading, and supply extremely broad torque and speed range. Generally available commercial air motors, however, have only 5% to 20% of ideal efficiency.

Robotic Gripper Cleans Up Space Debris

Currently there are about 500,000 pieces of human-made debris in space, orbiting our planet at speeds up to 17,500 miles per hour. This debris poses a threat to satellites, space vehicles, and astronauts aboard those vehicles. However, cleaning up the debris is problematic. For example, suction cups don’t work in a vacuum, and traditional sticky substances like tape are largely useless because the chemicals they rely on can’t withstand extreme temperature swings.

Wireless Magnetic Field Powers Folding Robots

A team of researchers at the Wyss Institute for Biologically Inspired Engineering and the John A. Paulson School of Engineering and Applied Sciences (SEAS) at Harvard University has created battery-free folding robots that are capable of complex, repeatable movements powered and controlled through a wireless magnetic field. The system requires only basic, passive electronic components on the robot to deliver an electric current, and the structure of the robot itself takes care of the rest.
