Scientists have established that ultrasound waves can spin a 200 nanometers wide rod up to...

Scientists at the National Institute of Standards and Technology (NIST) have discovered that a gold nanorod submerged in water and exposed to high-frequency ultrasound waves can spin at an incredible speed of 150,000 RPM, about ten times faster than the previous record. The advance could lead to powerful nanomotors with important applications in medicine, high-speed machining, and the mixing of materials.  Read More

Researchers working at MIT’s Department of Mechanical Engineering claim to have produced a sponge-like substance that helps convert water to steam using sunlight one-hundredth as bright as that required by conventional steam-producing solar generators. A composite of graphite flakes layered on a bed of carbon foam, the new material is reported to convert as much as 85 percent of received solar energy into steam.  Read More

A mouse's small intestine, as made visible using nanojuice

When someone suffers from a gastrointestinal disorder such as celiac disease, Crohn's disease or irritable bowel syndrome, it's standard practice for doctors to take a look at the state of their small intestine. This is typically done by having them drink a rather unpleasant-tasting barium solution, and then submitting to x-rays, an MRI or ultrasound. According to scientists at New York's University at Buffalo, however, all of those imaging techniques have serious shortcomings. Their proposed solution? A stiff drink of nanojuice.  Read More

Lawrence Livermore Engineer Xiaoyu 'Rayne' Zheng studies a macroscale version of the unit ...

Imagine materials strong enough to use in building airplanes or motor cars, yet are literally lighter than air. Soon, that may not be so hard to do because a team of researchers from MIT and Lawrence Livermore National Laboratory (LLNL) have developed new ultra-lightweight materials that are as light as aerogel, but 10,000 times stiffer, and may one day revolutionize aerospace and automotive designs.  Read More

There's gold in that thar belly – or at least there might soon be, if a new form of liposu...

Liposuction may be a popular method of instant body fat reduction, but it certainly isn't perfect. Patients can experience bruising, there can be lumps that have to be addressed with a second procedure, plus things other than fat cells – such as connective tissue and nerves – can inadvertently also get removed. Two researchers, however, are developing what could be a better form of liposuction, that involves first using injected gold microparticles to melt the fat.  Read More

A new type of quantum dot could lead to cheaper solar cells and better satellite communica...

Researchers at the University of Toronto have manufactured and tested a new type of colloidal quantum dots (CQD), that, unlike previous attempts, doesn't lose performance as they keep in contact with oxygen. The development could lead to much cheaper or even spray-on solar cells, as well as better LEDs, lasers and weather satellites.  Read More

Researchers at the University of California, Riverside have developed a new graphene-based supercapacitor that uses a nanoscale architecture to double its energy and power performance compared to commercially-available alternatives. This breakthrough is another important step toward making supercapacitors viable for use in fast-charging, high-performance electric cars and personal electronics.  Read More

Scientists at the Cockrell School of Engineering at the University of Texas have built and tested what appears to be the world's smallest, fastest, and longest-running nanomotor yet – so small that it could fit inside a single cell. The advance could be used to power nanobots that would deliver specific drugs to individual living cells inside the human body.  Read More

Researchers at the Institute of Photonic Sciences (ICFO) have developed a lab-on-a-chip device that can detect protein cancer markers in a drop of blood, working as a very early cancer-detection system. The device can detect very low concentrations of markers and is reliable, cheap and portable, making it attractive for deployment in remote areas of the world.  Read More

What if you could 3D print small devices that mimicked some of the functions of human organs, to address specific issues? That's what scientists at the University of California, San Diego have done by 3D-printing a liver-like device that's claimed capable of safely detoxifying blood.  Read More
