Anthrax toxin, secreted by the anthrax bacterium, is made of proteins and toxic enzymes that bind together to inflict damage on a host organism. Rather than targeting the anthrax bacterium or toxin – the approach taken by the majority of current therapies – the new inhibitor blocks the receptors where anthrax toxin attaches in the …
From www.nanotech-now.comMPhase has about 25 employees, most of which have been assigned to the task of helping to make its magnetometer 50 times smaller and 1,000 times more sensitive than the most powerful devices on the market today. While current devices are expensive, bulky and require supercooling to -455 F, the model in progress at …
they have developed a second generation “lab on a silicon chip” called the MitoChip v2.0 that for the first time rapidly and reliably sequences all mitochondrial DNA. Mitochondria, the energy-producing organelles that power our cells, are unique because they are equipped with their own genetic instructions distinct from the DNA stored in the cell nucleus. …
Nanoscale “guitar strings” that vibrate at more than one billion times per second could detect and identify individual molecules. A group led by Alex Zettl, a condensed matter physicist at the University of California, Berkeley, US, used electron-beam lithography and reactive ion etching to create a trench 300 nanometres across with electrodes on either side …
Immediate personal action that can be taken. Analyze your own homes energy consumption and try to optimize energy usage in the most cost effective way. The US dept of energy has advice and special online calculators to help you make your plans. Some of the best first steps usually are * Caulk and weatherstrip windows …
Georgia Institute of Technology researchers haveconducted successful test flights of a hydrogen-powered unmannedaircraft believed to be the largest to fly on a proton exchangemembrane (PEM) fuel cell using compressed hydrogen. Fuel cellshave more fuel efficiency potential than regular engines and lesspollution. Fuel cells, which create an electrical current when they converthydrogen and oxygen into water, …
Controlling the life and death of cells is important for fighting cancer and possible life extension. Researchers at the European Molecular Biology Laboratory [EMBL] in Heidelberg have now discovered how one of these signaling pathways controls the life and death of cells in the fruit fly. The study will be published in this week’s issue …
A scientist at North Carolina State University has discovered that the tiny grains comprising many bulk materials can potentially contain nearly zero structural imperfections when the grains are smaller than a certain critical size, typically a few to several nanometers. Materials created with grains of the right (optimal) size could be structurally flawless. Not only …
Quantronium are superconducting qubits created in France that Dwave purchased the rights to in 2003 The quantronium circuit is a superconducting quantum bit (qubit) made of aluminum and aluminum oxide. It includes two small tunnel junctions and a larger one inserted in a superconducting loop. The small junctions define a superconducting island capacitively coupled to …
Opening a whole new interface between nanotechnology and neuroscience, scientists at Harvard University have used slender silicon nanowires to detect, stimulate, and inhibit nerve signals along the axons and dendrites of live mammalian neurons. Harvard chemist Charles M. Lieber and colleagues report on this marriage of nanowires and neurons this week in the journal Science. …
hahyaan Desai, a Cornell graduate student has created a practical MEMS video display device based on carbon fibers. Carbon fiber rods supporting this tiny mirror can be made to bend up to 90 degrees millions of times without showing fatigue. The technology could be used to create a video projector on a chip. Desai has …
