Nanoscribe Will Sell a Micro 3-D Printer That Creates Tiny Structures in Seconds Nanoscribe, a spin-off from the Karlsruhe Institute of Technology in Germany, has developed a tabletop 3-D microprinter that can create complicated microstructures 100 times faster than is possible today. “If something took one hour to make, it now takes less than one minute,” says Michael Thiel, chief scientific officer at Nanoscribe. While 3-D printing of toys, iPhone covers, and jewelry continues to grab headlines (see “The Difference Between Makers and Manufacturers”), much of 3-D printing’s impact could be at a much smaller scale. Micrometer-scale printing has shown promise for making medical and electronic devices. Thiel says it should be possible to speed up his company’s microprinting technique even more in the future.

World's smallest, fastest nanomotor can fit inside a single cell Researchers at the Cockrell School of Engineering at The University of Texas at Austin have built the smallest, fastest and longest-running tiny synthetic motor to date. The team's nanomotor is an important step toward developing miniature machines that could one day move through the body to administer insulin for diabetics when needed, or target and treat cancer cells without harming good cells. With the goal of powering these yet-to-be invented devices, UT Austin engineers focused on building a reliable, ultra-high-speed nanomotor that can convert electrical energy into mechanical motion on a scale 500 times smaller than a grain of salt. Mechanical engineering assistant professor Donglei "Emma" Fan led a team of researchers in the successful design, assembly and testing of a high-performing nanomotor in a nonbiological setting. The team's three-part nanomotor can rapidly mix and pump biochemicals and move through liquids, which is important for future applications.
GAO 25/05/10 Nanotechnology: Nanomaterials Are Widely Used in Commerce, but EPA Faces Challenges in Regulating Risk Nanotechnology involves the ability to control matter at the scale of a nanometer--one billionth of a meter. The world market for products that contain nanomaterials is expected to reach $2.6 trillion by 2015. In this context, GAO (1) identified examples of current and potential uses of nanomaterials, (2) determined what is known about the potential human health and environmental risks from nanomaterials, (3) assessed actions EPA has taken to better understand and regulate the risks posed by nanomaterials as well as its authorities to do so, and (4) identified approaches that other selected national authorities and actions U.S. states have taken to address the potential risks associated with nanomaterials. GAO analyzed selected laws and regulations, reviewed information on EPA's Nanoscale Materials Stewardship Program, and consulted with EPA officials and legal experts to obtain their perspectives on EPA's authorities to regulate nanomaterials.

understand fractal, legos of life The generic structure of an alpha amino acid in its un-ionized form Many important proteinogenic and non-proteinogenic amino acids also play critical non-protein roles within the body. For example, in the human brain, glutamate (standard glutamic acid) and gamma-amino-butyric acid ("GABA", non-standard gamma-amino acid) are, respectively, the main excitatory and inhibitory neurotransmitters; hydroxyproline (a major component of the connective tissue collagen) is synthesised from proline; the standard amino acid glycine is used to synthesise porphyrins used in red blood cells; and the non-standard carnitine is used in lipid transport. Nine proteinogenic amino acids are called "essential" for humans because they cannot be created from other compounds by the human body and, so, must be taken in as food. Others may be conditionally essential for certain ages or medical conditions. Essential amino acids may also differ between species.
Research In Review: Paper Promise Paper Promise Peering through the lab window to a limitless world of uses in industry is an amazing new material that some day could be as commonplace as plastic. By Don Wood When Sumio Iijima of NEC Laboratories in Japan discovered carbon nanotubes in 1991, he set off a worldwide gold rush in academic, government and industrial labs to find practical uses for these extraordinary molecules.
Nanotechnology and Nanomedicine Medical Devices and Applications Nanotechnology involves the science and technology of devices and materials, such as drug delivery systems or electronic circuits, that are created on extremely tiny scales – as small as molecules and even atoms. Nanotechnology also involves manipulation of structure matter at molecular levels, involving different fields and specialties such as chemistry, engineering, electronics, medicine and others. All of these fields of study and pursuit are concerned with bringing existing technologies down to a very tiny scale that is measured in, 'nanometers,' which is a billionth of a meter, or about the size of six carbon atoms in a row. The processes used both today and in the past in the creation of industrial products have involved pushing piles of millions of atoms together through mixing, grinding and heating, a process that is very imprecise. Scientists are now able to pick up individual atoms and assemble them into structures, or cause particular chemical reactions.
Nano-Robots That Compute With DNA Installed Into Living Cockroach Scientists have inserted DNA-based nanobots into a living cockroach, which are able to perform logical operations. Researchers say the nanobots could eventually be able to carry out complex programs, to diagnose and treat disease. These DNA machines (or origami robots, so-called since they can unfold and deliver drugs stored within) carry fluorescent markers, allowing researchers to tell where in the roach's body they are traveling and what they are doing. Incredibly, the "accuracy of delivery and control of the nanobots is equivalent to a computer system," New Scientist reported.
USDA 27/04/15 USDA Awards $3.8 Million in Grants for Nanotechnology Research Printer-friendly version PDF version WASHINGTON, April 27, 2015 – The U.S. Department of Agriculture's (USDA) National Institute of Food and Agriculture (NIFA) today announced more than $3.8 million in funding to support grants focused on using nanotechnology to find solutions to societal challenges such as food security, nutrition, food safety, and environmental protection. Hertz "Megahertz", "MHz", "Gigahertz" and "GHz" redirect here. Top to bottom: Lights flashing at frequenciesf = 0.5 Hz (hertz), 1.0 Hz and 2.0 Hz, i.e. at 0.5, 1.0 and 2.0 flashes per second, respectively. The time between each flash – the period T – is given by 1⁄f (the reciprocal of f), i.e. 2, 1 and 0.5 seconds, respectively. The hertz (symbol Hz) is the unit of frequency in the International System of Units (SI) and is defined as one cycle per second. It is named for Heinrich Rudolf Hertz, the first person to provide conclusive proof of the existence of electromagnetic waves. One of the unit's most common uses is in the description of sine waves and musical tones, particularly those used in radio and other audio-related applications. It is also used to describe the speeds at which computers and other electronics are driven.
researcher's "buckypaper" is stronger than steel at a fraction of the weight by Barry Ray Working with a material 10 times lighter than steel—but 250 times stronger—would be a dream come true for any engineer. If this material also had amazing properties that made it highly conductive of heat and electricity, it would start to sound like something out of a science fiction novel. Yet one Florida State University research group, the Florida Advanced Center for Composite Technologies (FAC2T), is working to develop real-world applications for just such a material.
