Nanotech, Chem and Materials
More than 15 years ago scientists discovered a way to stop a particular gene in its tracks. The Nobel Prize-winning finding holds tantalizing promise for medical science, but so far it has been difficult to apply the technique, known as RNA interference, in living cells.
Researchers have captured time-series snapshots of a solid as it evolves on the ultra-fast timescale. Using femtosecond X-ray free electron laser pulses, the team is able to observe condensed phase dynamics such as crack formation, phase separation, rapid fluctuations in the liquid state or in biologically relevant environments.
The latest engineering feat to emerge from the laboratories at Harvard’s School of Engineering and Applied Sciences has been largely accomplished with the aid of kitchen mixers.
A new study into the potential health hazards of the revolutionary nano-sized particles known as ‘buckyballs’ predicts that the molecules are easily absorbed into animal cells, providing a possible explanation for how the molecules could be toxic to humans and other organisms.
Researchers at North Carolina State University have discovered that adding tiny bits of gold to a failed HIV drug rekindle the drug's ability to stop the virus from invading the body's immune system.
A major study published today in Nature Nanotechnology suggests some forms of carbon nanotubes – a poster child for the “nanotechnology revolution” – could be as harmful as asbestos if inhaled in sufficient quantities.
Whether for stopping cars or bullets, titanium is the material of choice, but it has always been too expensive for all but the most specialized applications. That could change, however, with a non-melt consolidation process being developed by Oak Ridge National Laboratory and industry partners.
Researchers at the Center for Quantum Devices at the McCormick School of Engineering at Northwestern University have recently doubled the efficiency of infrared lasers under the U.S. Defense Advanced Research Projects Agency’s Efficient Mid-wave Infrared Lasers (EMIL) program.
How advanced IS chemistry these days?
Scientists at UC San Diego, UC Santa Barbara and MIT have developed nanometer-sized “nanoworms” that can cruise through the bloodstream without significant interference from the body’s immune defense system and—like tiny anti-cancer missiles—home in on tumors.
In the rapid and fast-growing world of nanotechnology, researchers are continually on the lookout for new building blocks to push innovation and discovery to scales much smaller than the tiniest speck of dust.
Dr. Hibbert may soon be able to diagnose Homer's heart attacks using saliva and nano-technology, according to a new study headed by researchers at the University of Texas at Austin.
The world was in shock when in 2001 the Talibans destroyed two ancient colossal Buddha statues in the Afghan region of Bamiyan. Behind those statues, there are caves decorated with precious paintings from 5th to 9th century A.D.
A breakthrough by scientists from the University of Glasgow could see the storage capacity of an iPod increase 150,000 times.
