Punjab to have police station to tackle cyber-crime
The Punjab Police Monday announced that a state-of-the-art cyber crime police station
and forensic science laboratory would be set up in the state.
Institutes The town is home to the Vishveshvaranand Institute of Sanskrit and Indological
Studies (VSIS) at Sadhu Ashram on Hoshiarpur Una road, which may receive university
status in the future.
Revised Theory Suggests Carbon Dioxide Levels Already in Danger Zone
The authors, who include two Yale scientists, assert that to maintain a planet similar
to that on which civilization developed, an optimum CO2 level would be less than
350 ppm — a dramatic change from most previous studies, which suggested a danger
level for CO2 is likely to be 450 ppm or higher. Atmospheric CO2 is currently 385
parts per million (ppm) and is increasing by about 2 ppm each year from the burning
of fossil fuels (coal, oil, and gas) and from the burning of forests.
“This work and other recent publications suggest that we have reached CO2 levels
that compromise the stability of the polar ice sheets,How fast ice sheets and sea
level will respond are still poorly understood, but given the potential size of the
disaster, I think it’s best not to learn this lesson firsthand.” The statement is
based on improved data on the Earth’s climate history and ongoing observations of
change, especially in the polar regions. The authors use evidence of how the Earth
responded to past changes of CO2 along with more recent patterns of climate changes
to show that atmospheric CO2 has already entered a danger zone.
Controlling the flow of heat could be another way to store digital information
Someday, computers might store information using not only electric charges or magnetism,
but also tiny packets of heat called phonons. Such heat-based memory is theoretically
possible within the laws of physics, new research shows, and this memory would be
durable and could be read without destroying the information — two key requirements
for useful data storage.
Circuits based on quantum packets of heat rather than electric charges could enable
computers to use waste heat — which is currently just shed to keep a processor from
overheating — to perform useful computations and store information. A surge of research
in the last few years on the physics of controlling the flow of heat packets has
yielded designs for heat-based diodes, transistors and logic gates that perform AND,
OR and NOT operations.
Unlike the electrons in an electric circuit, phonons in a thermal circuit are not
actually particles. Instead, phonons are discrete units of vibration among the atoms
in a solid. The stronger these vibrations are, the hotter the solid will be. In materials
that conduct heat, phonons travel through the substance just as electrons travel
through electrical conductors.
Concentrated heat normally tends to dissipate over time, which would seem to make
heat-based memory impossible. Normally, heat flows faster when the temperature difference
between two materials is greater, which is why a red-hot burner will heat a pot of
water faster than a burner on medium. But the team previously showed that materials
can be designed to work in the opposite way, so that a greater temperature difference
causes heat to flow more slowly. This reversed response is what allows phonons at
one of two temperatures — representing the “on” or “off” of digital memory — to stay
at that temperature long enough to make the thermal memory useful.
Violent Video Games Affect Boys Biological Systems
In the study boys (12-15) were asked to play two different video games at home in
the evening. The boys’ heart rate was registered, among other parameters. It turned
out that the heart rate variability was affected to a higher degree when the boys
were playing games focusing on violence compared with games without violent features.
Differences in heart rate variability were registered both while the boys were playing
the games and when they were sleeping that night. The boys themselves did not feel
that they had slept poorly after having played violent games.
The results show that the autonomous nerve system, and thereby central physiological
systems in the body, can be affected when you play violent games without your being
aware of it. It is too early to draw conclusions about what the long-term significance
of this sort of influence might be. What is important about this study is that the
researchers have found a way, on the one hand, to study what happens physiologically
when you play video or computer games and, on the other hand, to discern the effects
of various types of games.
It is hoped that it will be possible to use the method to enhance our knowledge of
what mechanisms could lie behind the association that has previously been suggested
between violent games and aggressive behavior.
Getting the Solution Of Hair Loss
After six years of research scientists have succeeded in identifying a gene that
is responsible for a rare hereditary form of hair loss known as Hypotrichosis simplex.
The scientists are the first to identify a receptor that plays a role in hair growth.
They now hope that their research findings will lead to new therapies that will work
with various forms of hair loss.
Although Hypotrichosis simplex is very uncommon, it may prove critical in our search
for an understand of the mechanisms of hair growth. The disease is inherited and
affects both men and women. Sufferers generally begin to go bald during childhood.
The process of hair loss (alopecia) then advances with age, especially around the
The cause of Hypotrichosis simplex in the form examined in this project is a genetic
defect. It prevents certain receptor structures on the surface of hair follicle cells
from being correctly formed. It has been found that when messengers from outside
bind to these receptors they trigger a chain reaction in the cell interior which
is apparently needed for the hair follicle to function normally. Such a receptor
that plays a specific role in hair growth was previously unknown to scientists.
