Nanomachines are structures just one molecule in size (a few dozen atoms or so) that do work. When researchers added a small amount of water to the solvent that surrounded the nanomachines, the machines moved much faster.
Discovering how to optimize these tiny machines is important for the development of things like molecular computers and surfaces that can change properties.
Researchers are developing nanobots that can destroy plaque build-up in arteries. These nanobots have a magnetic core, which allows physicians to track their position in the bloodstream in real-time. The physicians can then control the bots' movements and plaque destruction via a remote monitor, like an MRI.
This means that, in the future, plaque build-up could be removed without surgery, or other invasive medical procedures. Pretty cool!

Archaeologists have uncovered a 30-foot by 6-foot frieze inside the base of a pyramid depicting deified Maya rulers. Much of the frieze's red, blue and yellow paint has been preserved by debris that had fallen over the frieze. Here's a link to the full report of the finding by archaeologist Francisco Estrada-Belli’s team at the Holmul Archaeological Project in Guatemala.
“This is a unique find. It is a beautiful work of art and it tells us so much about the function and meaning of the building, which was what we were looking for,” said Estrada-Belli. The carving depicts human figures in a mythological setting, suggesting these may be deified rulers. The team had hoped to find clues to the function of this building, since the unearthing of an undisturbed tomb last year. The burial contained an individual accompanied by 28 ceramic vessels and a wooden funerary mask.

Using semiconductor nanowire transistors, researchers at the Lawrence Berkeley National Laboratory have created a flexible sensor that lights up when touched. The harder it's pressed the brighter the lights. It's paper-thin, flexible nature could allow it to be laminated to any surface, which is quite different from the rigid touchscreens we find on iPhones, computer screens, and ATMs, for example. This new technology could be used to give robots a finer sense of touch, create a wallpaper that doubles as a touchscreen, or laminate dashboards to allow drivers to change electronic controls by waving their hand.

Currently, the electrical signals in silicon-based, implantable sensors are disrupted by the electrolytes in the body, resulting in unreliable readings. This new, ultra-thin coating blocks the electrolytes and allows the sensors to continue functioning accurately within the body. These coated sensors are first slated to be used to detect early stages of organ transplant rejection, but could have a lot of other possible applications in the future.
Researchers at the University of Adelaide have developed a new nanomaterial that could help reduce CO2 emissions produced by coal-fired power plants. This new material acts like a sponge and “soaks up” the carbon dioxide before it is released into the atmosphere by trapping the CO2 molecules in tiny nano-sized pores. This new material is potentially much more energy efficient than other, current methods of separating out CO2 from power plant emissions.

And researchers have now figured out certain factors – like blood type – that can make people be more tasty targets for the little buzzers. Question, do you think mosquitoes prefer to strike beer drinkers? Click here to find the answer to that, and other factors that can impact your appeal to mosquitoes.

In the presence of disease-causing pathogenic bacteria, tiny nanocapsules release dye that fluoresces under UV light. Currently, these wound dressings are being used for pediatric burn victims, whose immature immune systems make them particularly susceptible to infection.
