- Billion-year ultra-dense memory chip developed
- There's always been an inverse relationship between density and durability when it comes to data storage. Today's silicon memory chips contain a lot of density, but with a lifespan of just a few decades, they lack durability. Yet primitive forms of storage such as information carved in stone are highly...

- Solar gets green, I mean really green, like chlorophyll green
- What are the best solar collectors in the world. Dandelions, Douglas-fir, agave, tulips--any number of plants youmight see in nature or a garden. Now some British scientists say they've found a way to build solar panels that mimic plants. Plants light harvest, and so do...

- Gold nanoparticles purified air in old churches
- Chemists from Queensland University of Technology QUT, Australia, have found that the air in medieval European churches was purified by gold nanoparticles used to paint their stained glass windows. As said the team leader, 'glaziers in medieval forges were the first nanotechnologists.' [This is not completely true: nanocosmetics were used...

- Nanospheres moving faster than light?
- In recent years, I don't think I've spent a month without a report about a new way to exceed the speed of light. Yesterday, University of Pennsylvania researchers announced a theoretical way to increase the speed of pulses of light which could bring optical computing closer to reality. The scientists...

- Nanoparticles used to trap oil drops
- Rice University researchers have found a new way to spontaneously assemble nanoparticles into bag-like sacs. Their 'nanobatons' could be used to clean up oil spills by trapping oil droplets in polluted waters. These nanoparticles could even be more useful for delivering drugs. The researchers found that 'ultraviolet light and magnetic...

- Nanotechnology-based chicken feed?
- In order to keep healthy the 200 million chicken raised in South Carolina -- and the humans who ate them -- Clemson University researchers are using nanoparticles. They call this intelligent chicken feed. They have built 'nanoparticles that mimic the host cell surface and lock to targeted pathogens. The particles...

- Antibacterial paint is on the horizon
- Using a method similar to how the body breaks down fats, scientists have found a way to cheaply create silver nanoparticles for use in antibacterial paints. The really important point, according to Rice post-doc Ashavani Kumar, is we now have a general method for producing nano-particle dispersions....

- Remotely controlled nanoparticles fight tumors
- Many researchers around the world have tried to use nanoparticles to battle cancer. Now, researchers from the MIT have gone a step further. They found a way to 'talk' with the nanoparticles. In other words, they can control the nanoparticles and ask them to deliver drugs directly into tumors. Strands...

- Building nanowires to connect future chips
- As computer chips are getting smaller and smaller, it becomes crucial to find new ways to connect them. Canadian researchers have developed a method to produce self-assembled nanowires that are 5,000 times longer than they are wide. They've been able to obtain nanowires measuring only 10 nanometers in width, but...

- Nanotechnology boosts solar cells performance
- Physicists from the University of Illinois at Urbana-Champaign UIUC have improved the performance of solar cells by 60 percent. And they obtained this spectacular result by using a very simple trick. They've coated the solar cells with a film of 1-nanometer thick silicon fluorescing nanoparticles. The researchers also said that...

- A very robust 50-atom-thick nanosheet
- A team of U.S. scientists has discovered that by tightly packing molecules, they could obtain nanothin sheets of materials showing surprising strength. As one enthusiast researcher says, "It's an amazing little marvel." The team adds that "even when suspended over a tiny hole and poked with an ultrafine tip, the...

- Nano-hitchhikers to deliver drugs
- Another research team has found a way to use nanotechnology to deliver drugs. As you may know, polymeric nanoparticles are excellent carriers for delivering drugs. But as they are quickly removed from the blood, they are somewhat ineffective for the task. Now, researchers from the University of California at Santa...

- Nanoparticles reveal fingerprints
- According to Chemical Science, Israeli researchers have found new ways to use nanotechnology to reveal hidden fingerprints. Theyve used gold nanoparticles suspended in a stable solution of petrol ether. The nanoparticles "stick to the fingerprint residues through hydrophobic interactions." This new method produces high quality prints in just three minutes....

- A 'nano' cancer monitor implant
- It is very difficult for doctors to measure the evolution of tumors and if chemotherapy is actually working on cancer patients. This is why MIT researchers have developed a minuscule device that can be implanted directly into a tumor and containing nanoparticles designed to test for different substances associated with...

- Nanocosmetics are used since the Pharaohs
- French researchers have found that Egyptians, Greek and Romans were using nanotechnology to dye their hair several thousands years ago. In "Nanotechnology in Cosmetics - 2000 Years Ago...," Nanowerk Spotlight reports they were using lead compounds which generated lead sulfide PbS nanocrystals with a diameter of only 5 nanometers. At...
