A
diet containing too much red meat and not enough fruits and vegetables could increase
tour body’s ‘biological age’ and lead to health problems, according to a latest
research. Research led by the University of Glasgow and published on 29 April
in Aging, has found that a moderate increase in serum phosphate levels caused
by red meat consumption, combined with a poor overall diet, increases
biological age in contrast to chronological age (years of age). The study,
which looked at participants from the most deprived to the least deprived in
the NHS Greater Glasgow Health Board area, also demonstrates that deprived
males were the worst affected. Study suggests that accelerated biological
aging, and dietary derived males, were directly related to the frequency of red
meat consumption. Experts believe that excess red meat affects this group
because of their poor diet and “sub-optical fruit and vegetable intake”.

Indian scientists developed eco-friendly nanotechnology for water purification
The Scientists team from the Institute of
Advance Study in Science and Technology (IASST), Guwahati in Assam developed an
eco-friendly nanotechnology for water-softening applications. The report was
published online on 30 March 2016 in the journal Nanoscale and the authors are
Upama Baruah and Achyut Konwar of IASST. The green technology is the first of
its kind with potential to act as a biodegradable and green material for
water-softening applications. The technology is basically a biopolymer, which
uses a naturally occurring substance called Chitosan.
Soon, low-fat chocolate that melts in your mouth
You
may soon be enjoying your favourite sweet treat guilt-free as scientists have
found a way to make low-fat chocolate that easily melts in your mouth. Chocolate
is full of fat. But reducing the fat content of the confection makes it harder
and less likely to melt in your mouth, researchers said. Researchers at KU
Leuven in Belgium found that adding limonene could improve lower fat versions
texture and ability to melt. The researchers focused on the crystallization of
cocoa butter, which undergoes several important transformations at different
times and temperatures. The researchers examined crystallization at 17 degrees
Celsius and 20 degrees Celsius using differential scanning calorimeter and
X-ray diffraction to examine cocoa butter profiles when limonene was added. The
Belgian researchers found that adding the compound accelerated cocoa butter crystallization
at 17 degrees Celsius, but inhibited cocoa butter crystallization at 20.

New Water-Based Polymer with tiny electronic can be put inside body
The
human body is a marvel, but it’s not perfect. There can be a defect, things can
break, and illness can strike with little or no warning. If we could augment
ourselves with electronics, we might be able to solve some of these problems. But
such devices have traditionally presented issues of their own: They’re often
hard, rigid pieces of silicon and plastic. The body doesn’t react well to them,
and they don’t work well inside you.
A
team of researchers at the Massachusetts Institute of Technology may have hit
upon a solution. They’ve developed a new form of hydrogel – a water-based
polymer that can look and feel like muscles and tendons. Such a gel could
contain tiny electronics that can monitor our insides, deliver medicine, or
provide needed electrical stimulus.
Since,
the hydrogel is flexible, it can bend and twist without breaking or tearing. And
because much of the human body is made from similar materials, there’s little
chance we would reject the material as a foreign object. We’re still some years
away from US Food and Drug Administration approval, but should that happen,
this new breed of hydrogel may prove to be the foundation upon which an entirely
new class of medical devices is built.
Supercomputer 'Param Kanchenjunga' unveiled at Sikkim NIT
On
17 April 2016, Sikkim Governor Shrinvas Patil formally unveiled Supercomputer named ‘Param Kanchenjunga’
at the National Institute of Technology (NIT) Sikkim. It is named after Kanchenjunga
Mountain (8586 m), the third highest mountain in the world. The Param
Kanchenjunga is the most powerful and fastest among all available at the 31
National Institute of Technology’s. It has been jointly developed by Pune based
Centre for Development of Advanced Computing (C-DAC) and the NIT Sikkim. The total
cost of the Supercomputer is around three crore rupees.
Tiny liquid metal for heat free soldering
Scientists
have developed micro-scale, liquid-metal particles that can be used for
heat-free soldering and fabricating, repairing and processing of metals – all at
room temperature. The project started as a search for a way to stop liquid
metal from returning to a solid. This is called ‘undercooling’ and it has been
widely studied for insights into metal structure and metal processing. Researchers
from Iowa State University in the US thought if tiny droplets of liquid metal
could be covered with a thin, uniform coating, they could form stable particles
of undercooled liquid metal.
Lab-made 'sand' to cool electronics
US
scientists have engineered a kind of ‘sand’ – made of silicon dioxide
nanoparticles coated with a polymer – that can inexpensively cool power-hungry
electronic devices. The unique surface properties of the ‘sand’ conduct heat at
a potentially higher efficiency than existing heat sink materials, researchers
said. The theoretical physics behind it is complicated, but the bottom line
could potentially be a new class of high-thermal-conductivity materials useful
for heat dissipation from power electronics with high fluxes.
