According to the GEM 2014 Global Report, an annual report on global entrepreneurship, nnovation-driven economieslike the U s. tend to have the greatest fear of failure and fewer aspiring entrepreneurs,
Spectography is used often to identify gems, and CEO Dror Oren adds, f someone wants to offer an application for diamonds that costs $1, 000,
#Discovery of water-containing gem points to vast oceans beneath the Earth The Earth transition zone is the part of the Earth that exists between the upper and lower mantle.
A group of geologists from the University of Alberta uncovered a water-containing gem that finally confirms this theory:
The tiny gem was an accidental find while the geologists were searching for a completely different mineral.
Their final results showed that the gem contained 1. 5 percent of its weight in water.
These ultra-cold gemstones effectively acted as prisons trapping the electrons and allowing the scientists to accurately establish their spin or value.
But the gems have important scientific uses, too. New research suggests that a certain type of artificial diamond can be used as a nanoscale temperature probe with unmatched precision over time
"We used microscopes similar to the ones jewelers use to see the clarity of precious gems.
Sekula said. 10 times as many Higgs particles means a flood of data to sift for gems LHC Run 2 will collide particles at a staggering 13 teraelectronvolts (Tev),
And with more Higgs, we'll have an easier time sifting the gems out of the gravel."
Pear-shaped and canary-yellow, the gem cost $22, 000-a bargain. Mills, the chief executive officer of CMC Technology Consulting in Baton rouge, La.
While man-made gems make up just a fraction of the $80 billion global diamond market, demand is increasing as buyers look for cheaper stones that are cheaper-and free of ethical taint.
The technology has progressed to the point that experts need a machine to tell synthesized gems apart from those extracted from mines or rivers.
and Warren Buffett's Helzberg Diamonds are beginning to stock the artificial gems.""To a modern consumer,
The companies that dominate the market for natural gems, including Russia's Alrosa and De beers,
compared with 146 million carats of natural gems mined in 2013, estimates researcher Frost & Sullivan.
In July, mining companies won a major marketing victory when the International organization for Standardization ruled that man-made gems must be called synthetic, lab-grown,
#Geometrically Encoded Magnetic Sensors (GEMS) for High-resolution Remote Biological Sensing To date, most efforts to image highly localized biochemical conditions such as abnormal ph
The novel devices, called geometrically encoded magnetic sensors (GEMS), are microengineered metal-gel sandwiches about 5 to 10 times smaller than a single red blood cell, one of the smallest human cells.
and the change over time was sensed by the GEMS and recorded through real-time shifting in resonant frequencies.
which GEMS can be employed for biomedical uses.""That would require, among other things, further miniaturization.
The 0. 5 to 2 m diameter GEMS in the experiments are already small enough for many in vitro and other possible non-biological applications,
One of the most significant features of GEMS is that they can be tuned"in fabrication to respond to different biochemical states
respectively So placing two different populations of GEMS at the same site makes it possible to track changes in two different variables at the same time--a capability the researchers demonstrated by placing GEMS with two different dimensions in the same location and detecting
Functionally, the GEMS in the current effort are advanced more in that they change their shape in response to stimuli;
synthetic version of the precious gem can light up early-stage cancers in nontoxic, noninvasive Magnetic resonance imaging (MRI) scans.

Spinel can be mined as a gemstone; a famous example is the Black Prince Ruby, which is actually spinel with a color dopant.
and polish this just like you would do gems, says Sanghera. This is the most costly part of the process. ne of the things wee looking at is,
For this new estimate, Tarduno and his team looked at tiny zircon gemstones in Western australia that date back to the earliest two eons in the planet's history the Archean and Hadean periods.
forming a structure like a crystal rod with an embedded array of gems. Details of the new method are published in the journal Nature Materials.
