IamAtribalist: I believe dey r quite different and misinterpreted in nigeria. A phase is a region with uniform chemical and physical properties and is separated by distinguishable boundaries. • States of matter are the forms in which different phases can exist. Solid, liquid and gas are the most common states of matter on earth. • In one state of matter, many forms of phases can exist. For example consider the bottle with gasoline and water. Both are in a liquid state, but in different phases. The same concept can be applied to solids, though the gasses tend to violate this, but not explicitly. |

Science/Technology / Extreme Pressure Causes Osmium To Change State Of Matter by frankg1(m): 3:57pm On Sep 12, 2015 |
Using metallic osmium (Os) in experimentation,
an international group of researchers have
demonstrated that ultra-high pressures cause
core electrons to interplay, which results in
experimentally observed anomalies in the
compression behavior of the material.
Os is one of Earth's most exceptional elemental
materials, possessing the highest known density
at ambient pressure, one of the highest
cohesive energies and melting temperatures,
and an incompressibility that is almost
comparable to that of diamond.
Researchers believe that the ability to affect
core electrons – which do not participate in
chemical bonding – in metals like osmium will
open new opportunities in the search for new
states of matter and the synthesis of materials
with unique properties that do not exist at
ambient conditions.
"The international research team employed
extreme conditions that generated a
measurable change in osmium's high pressure
behavior," said Vitali Prakapenka, a scientist at
the University of Chicago's GeoSoilEnviros
Center for Advanced Radiation Sources
(GSECARS) beamline at the Advanced Photon
Source (APS), a U.S. Department of Energy's
(DOE) Office of Science User Facility at DOE's
Argonne National Laboratory.
"Although the theoretically predicted
electronic transition that involves pressure-
induced interaction between core (inner)
electrons is much weaker than typical
structural changes associated with valence
(outer) electrons, we were able to detect
experimentally changes in properties of this
highly-compressed material which are related
to the predicted phenomenon," said Leonid
Dubrovinsky of the Bayerisches Geoinstitut
(BGI) at Bayreuth University in Germany.
"We used micro-anvils made of super hard
nano-diamond to generate 770 gigapascals of
pressure (more than 7 million of atmospheres,
i.e. twice that of the center of the Earth) on
the osmium sample," BGI's Natalia
Dubrovinskaia said. The device for generating
ultra-high static pressures – a two-stage
diamond anvil cell – was developed by
Dubrovinsky and Dubrovinskaia, who published
this research technique in 2012.
A schematic of the pressure chamber of the
double-stage diamond anvil cell (dsDAC) for
ultra-high pressure generation and a photo of
a DAC produced at BGI. Semi-balls made of
nanocrystalline diamond of extraordinary
strength are attached to the culets of the
opposed gem quality diamonds of the DAC. A
sample of osmium, shown as a small red dot
on the top of the lower semi-ball, has a size of
ca. 3 microns. It is compressed between the
tips of the semi-balls, which are supported by
a pressure-medium (solidified inert gases or
paraffin) filling the pressure chamber of the
DAC. Ultra-high pressure is generated on the
sample due to the two-stage exertion of a big
force on a very small area. The diameter of the
semi-balls is about 10 microns. The diameter
of culets of the diamonds, to which the semi-
balls are attached, is 250 microns. Credit:
Elena Bykova, University of Bayreuth
"Measuring the effect of ultra-high pressure
required very accurate structural X-ray
diffraction experiments to reveal the
anomalous behavior of the lattice parameters
upon compression," Prakapenka said. "We
used state-of-the-art synchrotron techniques
capable of penetrating bulky pressure vessels
to probe tiny samples with a typical size of
around 1-4 microns. We have used a very
intense tightly focused high-energy X-ray beam
that is only available at third-generation
synchrotron facilities."
The research is detailed in the paper "The most
incompressible metal osmium at static
pressure above 750 gigapascals," published in

Science/Technology / Could We Terraform The Sun? by frankg1(m): 2:24pm On Sep 12, 2015 |
In the list of crazy hypothetical ideas,
terraforming the sun has to be one of the top
10. So just how would someone go about doing
terraforming our sun, a star, if they wanted to
try?
In our series on terraforming other worlds.
We've covered Mars, Venus, the Moon and
Jupiter. Even though I solved the problem of
how to terraform Jupiter (you're welcome,
science), you wanted to take things to the next
level and you demanded I sort out how to
terraform the sun . Seriously? The sun. Fine…
here we go.
Let's see what we've got to work with here. It's
a massive ball of plasma, containing 333,000
times more mass than the Earth. It's about
74% hydrogen and 25% helium with a few
other trace elements. There's no solid surface
to stand on it, so we need to fix that.
The average temperature on the surface of the
sun is about 5,500 Celsius, while the average
temperature on Earth is about 15 C. Iron boils
at only 2,800 degrees, so… that's probably too
hot. We'll need to cool it down.
The gravity on the surface of the sun is 28
times the gravity of Earth. If you could stand
on the surface of the sun, which you can't,
you'd be crushed flat. Okay, so we'll add
reduce the gravity… check.
There's no breathable atmosphere, there's no
solid ground, the sun generates deadly X-rays.
Oh, and don't forget about the terrible
sunburns from the ultraviolet radiation. So, what's the list? Hot fire unbreathable pressure cooker goo surface gravity crushing machine. Sounds impossible, or does it? First, the gas. As we covered in a previous episode, scientists have actually considered ways that you might extract the hydrogen and helium off of a star like the sun, known as "stellar lifting". There are a few ways you could work this. You could zap the surface of the sun with a powerful laser, increasing the speed of solar wind in that area, forcing the sun to throw its mass off into space. Another method is to set up powerful magnetic fields around the sun's poles, and channel its hydrogen into jets that blast out into space. I'm not sure how you actually set up those magnetic fields, but that's not my problem. Once you're done with the sun, you've stripped away all its hydrogen and helium gas. What are you left with? About 5,600 times the mass of the Earth in heavier elements, like oxygen, silicon, gold, etc. Great! Except 5,600 sounds like a lot. Jupiter is only 316 times the mass of the Earth. We're looking to reform a "planet" with more than 10 times the mass of Jupiter. And not only that, but we had to kill the sun to make this work. You monsters. This is a terrible idea. What else could we do? If you're a science fiction fan, you've heard of a Dyson sphere. If not, you've got some TNG to catch up on. First proposed by Freeman Dyson, you cover an entire sun in a metal ball. Instead of the measly amount of energy that falls on Earth, this would allow you to capture 100% of the energy released by the sun: 384 yottawatts. According to Dyson and a variety of matheletes, you could dismantle all planets in the solar system and build a sphere at a distance of 1 Earth radii at 8 to 20 centimeters thick. That would give you a surface area 550 million times more than the Earth. Although, building an actual rigid sphere is probably unfeasible because it would be pretty unstable and eventually collapse. It probably makes more sense to build a swarm of satellites surrounding the sun, capturing its energy. Source:: Universe Today |

The Ashley Madison hack will have a serious effect on churches. According to Ed Stetzer, as many as 400 pastors, deacons, elders and church staff members may resign this Sunday after their names surfaced on the list of users revealed in the Ashley Madison hack. In a post on his Christianity Today blog, The Exchange, Stetzer said the number is based on “conversations with leaders from several denominations in the U.S. and Canada,” adding, “To be honest, the number of pastors and church leaders on Ashley Madison is much lower than the number of those looking to have an affair.” Along with being a contributing editor for CT , author and professor, Stetzer is the executive director of LifeWay Research, and a well- regarded expert on church leadership. He is also the executive editor of the Christian leadership publication Facts & Trends. All that to say, Stetzer is well-informed, and his number is likely accurate. Former social conservative lobbyist and Christian reality TV star Josh Duggar and Christian vlogger Sam Rader recently released their own statements, acknowledging that they were both users of the site, which facilitates adultery. http://www.relevantmagazine.com/slices/expert-400-church-leaders-will-resign-sunday-because-names-surfaced-ashley-madison-hack |

Science/Technology / Marijuana Use May Lower Sperm Counts 'quite A Lot' by frankg1(m): 1:19pm On Aug 29, 2015 |
Smoking marijuana more than once a week
may lower men's sperm counts by about a
third, according to a new study.
Researchers found that the men in the study
who smoked marijuana more than once a week
had sperm counts that were 29 percent lower,
on average, than those who did not smoke
marijuana , or used the drug less frequently.
The researchers thought that amount of
reduction in sperm count "was quite a lot,"
said study author Tina Kold Jensen, of the
University of Copenhagen in Denmark.
They also found that the sperm concentrations
(which is measured slightly differently than
sperm count) were 28 percent lower in the
men who smoked marijuana more than once a
week.
It is not clear why marijuana use may decrease
a man's sperm count and concentration, but it
may have something to do with how THC —
marijuana's psychoactive ingredient —
interacts with certain receptors in the testes,
the researchers said.
In the study, the researchers asked 1,215
Danish men ages 18 to 28 whether they used
marijuana and other drugs like amphetamine,
ecstasy and cocaine within the past three
months, and if so, how often. [11 Odd Facts
About Marijuana ]
The researchers also collect semen samples, to
measure the men's sperm counts and
concentrations.
About 45 percent of the men in the study said
they had smoked marijuana in the past three
months. About 10 percent of the study
participants had used marijuana as well as
recreational drugs during this time.
Moreover, in the men in the study who smoked
marijuana and used other recreational drugs,
the sperm counts were reduced by 55 percent,
and the sperm concentrations were reduced by
52 percent, compared with men who hadn't
used the drugs.
The researchers found that the men who had
smoked marijuana in the past three months
were also more likely to smoke cigarettes, and
consumed more alcohol and caffeine than
those who had not.
These lifestyle factors also could have affected
the men's sperm levels, so the researchers
took them into account, and the link between
marijuana and lower sperm levels held.
However, the study still does not prove that
the drug caused the lower sperm counts,
Jensen said.
"We cannot exclude the possibility that the
men who used marijuana generally have an
unhealthier lifestyle and health behavior,
which may also affect their semen quality and
hormone levels," the researchers said in the
study.
"It is … important to note that marijuana users
were distinct in several ways from nonusers,"
Dr. Michael L. Eisenberg of Stanford University
School of Medicine , who was not involved in
the new study, wrote in an editorial
accompanying the study in the journal. And
although the researchers adjusted for these
differences, such as higher rates of cigarette
smoking and alcohol consumption, they could
have still confounded the potential effects of
marijuana on sperm , he wrote.
Still, the new study "provides important
information for patients and providers
regarding the negative association between
marijuana use and semen quality," Eisenberg
wrote.
The study was published Aug. 16 in the
American Journal of Epidemiology. |
Science/Technology / Quantum "Spookiness" Passes Toughest Test Yet by frankg1(m): 1:06pm On Aug 29, 2015 |
It’s a bad day both for Albert Einstein and for hackers. The most rigorous test of quantum theory ever carried out has confirmed that the ‘spooky action at a distance’ that the German physicist famously hated — in which manipulating one object instantaneously seems to affect another, far away one — is an inherent part of the quantum world. The experiment, performed in the Netherlands, could be the final nail in the coffin for models of the atomic world that are more intuitive than standard quantum mechanics, say some physicists. It could also enable quantum engineers to develop a new suite of ultrasecure cryptographic devices. “From a fundamental point of view, this is truly history-making,” says Nicolas Gisin, a quantum physicist at the University of Geneva in Switzerland. Einstein’s annoyance In quantum mechanics, objects can be in multiple states simultaneously: for example, an atom can be in two places, or spin in opposite directions, at once. Measuring an object forces it to snap into a well-defined state. Furthermore, the properties of different objects can become ‘entangled’, meaning that their states are linked: when a property of one such object is measured, the properties of all its entangled twins become set, too. This idea galled Einstein because it seemed that this ghostly influence would be transmitted instantaneously between even vastly separated but entangled particles — implying that it could contravene the universal rule that nothing can travel faster than the speed of light. He proposed that quantum particles do have set properties before they are measured, called hidden variables. And even though those variable cannot be access, he suggested that they pre-program entangled particles to behave in correlated ways. In the 1960s, Irish physicist John Bell proposed a test that could discriminate between Einstein’s hidden variables and the spooky interpretation of quantum mechanics. He calculated that hidden variables can explain correlations only up to some maximum limit. If that level is exceeded, then Einstein’s model must be wrong. The first Bell test was carried out in 1981, by Alain Aspect’s team at the Institute of Optics in Palaiseau, France. Many more have been performed since, always coming down on the side of spookiness — but each of those experiments has had loopholes that meant that physicists have never been able to fully close the door on Einstein’s view. Experiments that use entangled photons are prone to the ‘detection loophole’: not all photons produced in the experiment are detected, and sometimes as many as 80% are lost. Experimenters therefore have to assume that the properties of the photons they capture are representative of the entire set. To get around the detection loophole, physicists often use particles that are easier to keep track of than photons, such as atoms. But it is tough to separate distant atoms apart without destroying their entanglement. This opens the ‘communication loophole’: if the entangled atoms are too close together, then, in principle, measurements made on one could affect the other without violating the speed-of- light limit. Entanglement swapping In the latest paper, which was submitted to the arXiv preprint repository on August 24 and has not yet been peer reviewed, a team led by Ronald Hanson of Delft University of Technology reports the first Bell experiment that closes both the detection and the communication loopholes. The team used a cunning technique called entanglement swapping to combine the benefits of using both light and matter. The researchers started with two unentangled electrons sitting in diamond crystals held in different labs on the Delft campus, 1.3 kilometers apart. Each electron was individually entangled with a photon, and both of those photons were then zipped to a third location. There, the two photons were entangled with each other — and this caused both their partner electrons to become entangled, too. This did not work every time. In total, the team managed to generate 245 entangled pairs of electrons over the course of nine days. The team's measurements exceeded Bell’s bound, once again supporting the standard quantum view. Moreover, the experiment closed both loopholes at once: because the electrons were easy to monitor, the detection loophole was not an issue, and they were separated far enough apart to close the communication loophole, too. “It is a truly ingenious and beautiful experiment,” says Anton Zeilinger, a physicist at the Vienna Centre for Quantum Science and Technology. “I wouldn’t be surprised if in the next few years we see one of the authors of this paper, along with some of the older experiments, Aspect’s and others, named on a Nobel prize,” says Matthew Leifer, a quantum physicist at the Perimeter Institute in Waterloo for Theoretical Physics, Ontario. “It’s that exciting.” A loophole-free Bell test also has crucial implications for quantum cryptography, says Leifer. Companies already sell systems that use quantum mechanics to block eavesdroppers. The systems produce entangled pairs of photons, sending one photon in each pair to the first user and the other photon to the second user. The two users then turn these photons into a cryptographic key that only they know. Because observing a quantum system disrupts its properties, if someone tries to eavesdrop on this process it will produce a noticeable effect, setting off an alarm. The final chink But loopholes, and the detection loophole in particular, leave the door open to sophisticated eavesdroppers. Through this loophole, malicious companies could sell devices that fool users into thinking that they are getting quantum-entangled particles, while they are instead being given keys that the company can use to spy on them. In 1991, quantum physicist Artur Ekert observed that integrating a Bell test into the cryptographic system also would ensure that the system uses a genuine quantum process. For this to be valid, however, the Bell test must be free of any loopholes that a hacker could exploit. The Delft experiment “is the final proof that quantum cryptography can be unconditionally secure”, Zeilinger says. In practice, however, the entanglement- swapping idea will be hard to implement. The team took more than week to generate a few hundred entangled electron pairs, whereas generating a quantum key would require thousands of bits to be processed per minute, points out Gisin, who is a co-founder of the quantum cryptographic company ID Quantique in Geneva. Zeilinger also notes that there remains one last, somewhat philosophical loophole, first identified by Bell himself: the possibility that hidden variables could somehow manipulate the experimenters’ choices of what properties to measure, tricking them into thinking quantum theory is correct. Leifer is less troubled by this ‘freedom-of- choice loophole’, however. “It could be that there is some kind of superdeterminism, so that the choice of measurement settings was determined at the Big Bang,” he says. “We can never prove that is not the case, so I think it’s fair to say that most physicists don’t worry too much about this.” http://www.scientificamerican.com/article/quantum-spookiness-passes-toughest-test-yet/ 1 Like |
