A Replacement Rises on the Bay - Interactive Feature. Monel. Monel is a trademark of Special Metals Corporation for a series of nickel alloys, primarily composed of nickel (up to 67%) and copper, with some iron and other trace elements.
Monel was created by David H. Browne, chief metallurgist for International Nickel Co. Monel alloy 400 is binary alloy of the same proportions of nickel and copper as is found naturally in the nickel ore from the Sudbury (Ontario) mines. Monel was named after company president Ambrose Monell, and patented in 1906.[2] One L was dropped, because family names were not allowed as trademarks at that time. A first step towards Minority Report ads from Inwindow Outdoor (demo) Erasing signs of aging in human cells now a reality. Scientists have recently succeeded in rejuvenating cells from elderly donors (aged over 100).
These old cells were reprogrammed in vitro to induced pluripotent stem cells (iPSC) and to rejuvenated and human embryonic stem cells (hESC): cells of all types can again be differentiated after this genuine "rejuvenation" therapy. The results represent significant progress for research into iPSC cells and a further step forwards for regenerative medicine. Inserm's AVENIR "Genomic plasticity and aging" team, directed by Jean-Marc Lemaitre, Inserm researcher at the Functional Genomics Institute (Inserm/CNRS/Université de Montpellier 1 and 2) performed the research. The results were published in Genes & Development on November 1, 2011. Japanese supercomputer blisters 10 quadrillion calculations per second.
Dynamic Periodic Table. Astronomy. Can evolution outpace climate change? The tide pool copepod Tigriopus californicus showed little ability to evolve heat tolerance over 10 generations (credit: Morgan Kelly, UC Davis) Ecologists at the University of California, Davis have determined that animals and plants may not be able to evolve their way out of the threat posed by climate change.
The ecologists examined the tide pool copepod Tigriopus californicus that is found from Alaska to Baja California, but found that the animals show little ability to evolve heat tolerance. The researchers grew the short-lived copepods in the lab for 10 generations, subjecting them to increased heat stress to select for more heat-tolerant animals. At the outset, copepods from different locations showed wide variability in heat tolerance. But within those populations, the ecologists were able to coax about a half-degree Celsius (about one degree Fahrenheit) of increased heat tolerance over 10 generations. Ref.: M. A high-fat diet may rapidly injure brain cells that control body weight. Speedier cell-phone circuitry. Graphene circuit (credit: Science/AAAS) Researchers at IBM have made the best integrated circuits yet from graphene, a material that promises much faster components than silicon allows, but has proven difficult to work with.
The team made the circuits using existing manufacturing methods, showing that graphene could be used to make faster, more power-efficient radio communications circuitry for cell phones, and other wireless devices. The researchers made a frequency mixer, combining one graphene transistor and two metal inductors. These devices are used in cell phones to convert the radio signal used to transmit information into another signal in a frequency range that the human ear can hear. The Goods: June 2011's Hottest Gadgets. Is ‘self-tracking’ the secret to living better? Quantified Self Guide - Livifi. Asteroid served up ‘custom orders’ of life’s ingredients. One of the Tagish Lake meteorite fragments (credit: Michael Holly, Creative Services, University of Alberta) Some asteroids may have been like “molecular factories,” generating life’s ingredients and shipping them to Earth via meteorite impacts, scientists at the University of Alberta have determined.
In January 2000, a large meteoroid exploded in the atmosphere over northern British Columbia, Canada, and rained fragments across the frozen surface of Tagish Lake. Pieces were collected within days and kept preserved in their frozen state. This ensured that there was very little contamination from terrestrial life. They found that various fragments had been exposed to different amounts of water, and suggest that water alteration may account for the diversity in amino acid production. The Tagish Lake meteorite provides a unique window into what was happening to organic molecules on asteroids four-and-a-half billion years ago, and the pre-biotic chemistry involved, the researchers said.

A graphene waveguide and splitter (credit: University of Pennsylvania) Engineers at the University of Pennsylvania have proposed the possibility of one-atom-thick, two-dimensional metamaterials by controlling the conductivity of sheets of graphene (a single layer of carbon atoms).
The engineers manipulated electromagnetic (EM) acoustic waves in the infrared spectrum. Algae Biodiesel Vertical Farms - Video. Researchers discover superatoms with magnetic shells. A proposed assembly of FeMg8 magnetic superatoms where the directions of magnetic moment are indicated by arrows (credit: Victor Medel/VCU) A team of Virginia Commonwealth University scientists has discovered a new class of “superatoms” — a stable cluster of atoms that can mimic different elements of the periodic table — with unusual magnetic characteristics that may have applications in spintronics.
The team examined the electronic and magnetic properties of clusters having one iron atom surrounded by multiple magnesium atoms. The team found that when the cluster had eight magnesium atoms, it acquired extra stability due to filled electronic shells that were far separated from the unfilled shells.
