DNA computers deliver drugs inside cockroaches

April 13th, 2014 at 8:06 am » Comments Off

As much computing power as a 8-bit computer. Nano-sized entities made of DNA that are able to perform the same kind of logic operations as a silicon-based computer have been introduced into a living animal. A computer inside a cockroach.    

Bionic plants use nanotechnology to boost photosynthesis

March 20th, 2014 at 10:39 am » Comments Off

Researchers embedded carbon nanotubes in the chloroplasts of the plants to create “artificial antennae.” Plants make life possible. Chloroplasts are the tiny organelles with a plant’s leaves. The chloroplasts use incoming sunlight to split water molecules and then knit together the energy-rich carbon and hydrogen compounds found in everything from food to fossil fuels. The […]

Tiny motors that fit inside human cells could one day treat diseases

A nanomotor inside a HeLa Cell. A Pennsylvania State University team has discovered that nanomotors made from tiny metal rods can be manipulated by sound waves and magnets, giving them precise control over their actions inside of cells.  

Flexible materials could provide new ways to control sound and light

February 4th, 2014 at 11:50 am » Comments Off

A new wrinkle in the control of waves. Flexible, layered materials textured with nanoscale wrinkles could provide a new way of controlling the wavelengths and distribution of waves, whether of sound or light. The new method, developed by researchers at MIT, could eventually find applications from nondestructive testing of materials to sound suppression, and could […]

Replacing batteries with super capacitors: Volvo’s quest to create the ultimate electric vehicle

November 5th, 2013 at 9:10 am » Comments Off

The battery is the biggest limitation for electric vehicles (EV).  Tesla, General Motors, Nissan and others install heavy batteries that limit vehicle range and performance. The batteries take up as much as 15% of the vehicle’s total weight.    

Researchers develop cheaper, longer-lasting futuristic copper foam batteries

October 28th, 2013 at 9:37 am » Comments Off

Prieto Battery’s copper foam. Power plants, wind farms, and smartphones all suffer from the same basic ailment — they lack cheap, reliable, long-life batteries to store large amounts of energy for when the sun goes down, the wind stops blowing, or the device is unplugged for a long time.      

Stanford engineers successfully build world’s first carbon nanotube computer

October 3rd, 2013 at 11:02 am » Comments Off

Researchers unveil the first working computer built entirely from carbon nanotube transistors. A group of  researchers at Stanford University have moved a step closer to answering the question of what happens when silicon, the standard material in today’s microelectronic circuits, reaches its fundamental limits for use in increasingly small transistors.    

Scientists create first smartphone attachment that can detect a single virus, nanoparticles

September 19th, 2013 at 8:18 am » Comments Off

UCLA smartphone virus scanner Scientists have finally developed a technology that makes it possible to avoid a trip to the doctor.  The UCLA Henry Samueli School of Engineering and Applied Science scientists have created a lightweight, virus-detecting device that attaches to a common smartphone and is able to scan the human body for human cytomegalovirus (HCMV) […]

Researchers demonstrate new method for harvesting energy from light

September 13th, 2013 at 12:44 pm » Comments Off

Hybrid optoelectronic nanostructures with controlled variation in photoconduction properties. University of Pennsylvania reasearchers have demonstrated a new mechanism for extracting energy from light, a finding that could improve technologies for generating electricity from solar energy and lead to more efficient optoelectronic devices used in communications.    

Researchers levitate nanoscale diamonds with a laser beam

August 15th, 2013 at 1:14 pm » Comments Off

University of Rochester researchers recently demonstrated how beams of light can actually levitate nanoscale diamonds. And while they’re not actually suggesting that we construct a light-driven hoverboard made of the precious gems, the things we might be able to do with floating diamonds are pretty cool in their own right.
