POLYMER PATCH
ENABLES REPAIR HEART DAMAGE WITHOUT STITCHES
Implanting a flexible polymer
patch into rats showed improved conduction of electrical impulses across the
heart scar tissue. The patch -- new technology enables to repair the tissues
without the need for stitches, says scientists. The new technology shown to
work in animal models reported the long lasting and significant advantage that
it can be stuck onto the heart. "Heart attacks create a scar which slows
and disrupts the conduction of electrical impulses across the heart. This leads
to potentially fatal disturbances of the heart rhythm. Our electrically
conducting polymer patch is designed to address this serious problem,” said
Professor Sian Harding from Imperial College London.
Patch consists of 3
components:
The patch is made from three
components: a film of chitosan, a polysaccharide found in crab shells that is
often used as a food additive; polyaniline, a conducting polymer that is grown
on top; and phytic acid, a substance found in plants which is added to the
polyaniline to switch it to its conducting state. "Conducting polymers
work when they are dry, but most become non-conducting in a very short time
when placed in bodily fluids," said Dr Damia Mawad from University of New
South Wales (UNSW in Australia.) The suture-less patch shown as stable and
retains it conductivity in physiological conditions for more than 2 weeks,
compared with the usual one day of other designs. Since stiches are required to
attach, it is minimally invasive and less damaging to the heart. The patch is
made to adhere to the heart tissue by shining a green laser on it. “We envisage
heart attack patients eventually having patches attached as a bridge between
the healthy and the scar tissue, to help prevent cardiac arrhythmia. However,
our patch is at the very early stages of this research. This technology can now
be used for basic research to gain insights into the interface between the
material and tissue," said Mawad.

Montblanc Benefits UNICEF With New Pen Collection
Headquartered in New York City, the United
Nations Children’s Fund, originally known as the United Nations International
Children's Emergency Fund (UNICEF), was created in 1946 to help mothers and
children in need. Montblanc has been collaborating with the
organization for the past 13 years, raising over $10 million to
benefit educational programs around the world.The new Montblanc for UNICEF collection of limited edition
writing instruments, timepieces, accessories and leather goods is the latest
demonstration of the company’s commitment to quality education. And to reinforce the universal nature of
writing, the multi-cultural aspect of language is incorporated into
the design of the Montblanc Meisterstück, Writing is a Gift pen collection. Six
handwritten characters are evident on each pen: the first letter from
each of six alphabets, including Roman, Hindi, Arabic and three Asian
characters. On a timely note, the items from the Writing Is A Gift
Collection sold between the first of this month and March 31,
2018, will benefit UNICEF.
“There is still much to be done to ensure that
every child around the world has proper access to an education, a cause
Montblanc has been proud to champion for the past 13 years,” explains Nicolas
Baretzki, Montblanc CEO. “This new initiative gives individuals who are as
passionate as we are about the written word the ability to own a Montblanc
piece that carries true purpose, and by doing so, making a valuable
contribution to the work of UNICEF in communities around the world where
children are not always given the opportunity to learn to read and write.
Writing is indeed a special gift that every child should enjoy.”
Blue Solitaire Edition.
The Montblanc Meisterstück, Writing is a Gift
collection of writing instruments is notably inspired by the Rosetta Stone,
which not only was a key to unlocking the meaning of hieroglyphs but also to
understanding the culture of ancient human civilizations. The alphabet motif is
interpreted through different design variations and as is usual with
Montblanc’s limited editions, there are several interpretations within the
collection.The Precious Resin Edition is crafted in polished black resin with
platinum-coated fittings. The cap is engraved with the first letter of the six
most used alphabets in the world alongside a single blue sapphire. The
collection includes a Fountain Pen LeGrand, Rollerball LeGrand, Ballpoint
Midsize, and in the smaller Fountain Pen Classique, Rollerball Classique and
Ballpoint Classique.The Doué Classique Edition features a black resin barrel
with a metal cap decorated with a mosaic of alphabet letters. It is available
in a Fountain Pen Classique with a rhodium-coated Au 750 gold nib, a Roller
Ball Classique and Ballpoint Classique, each featuring the six alphabet
characters encircling the cap top, enhanced by a single sapphire in UNICEF
blue. The Blue Solitaire Edition’s cap and barrel are adorned with an elegant
pattern created from the alphabet letters, which are on a blue lacquer
background embellished by fine silver-color lines and a 1.9mm sapphire set in
the cap top. The Blue Solitaire Edition comes in a Fountain Pen LeGrand with a
bicolor Au 750 gold handcrafted nib, as well as a Rollerball LeGrand and Ballpoint
Midsize.Finally, the Skeleton 149 Edition takes the alphabet motif to new
heights in a platinum-coated three-dimensional cutout of the six alphabet
characters, allowing the blue resin beneath it to show through the
intricate structure.
I think writing by hand
should be a wave of the future rather than a thing of the past.
ROBOTIC AMBULANCE COMPLETES FIRST
SOLO FLIGHT TEST
JERUSALEM An autonomous flying
ambulance, launched by an Israeli company has successfully completed its first
solo test flight. The newly developed ambulance likely replaces the helicopters
to offer a potential solution for challenging search and rescue missions. Currently
helicopters are offering the best transportation option in most cases. However,
these vehicles need clear areas to land, and in the case of war zones,
helicopters tend to attract enemy fire. Last month, the company flew the
Cormorant on the craft's first solo flight over real terrain. The vehicle is
designed to eventually carry people or equipment without a human pilot on
board, according to 'Live Science' reports. Rather than using propellers or
rotors to fly, the Cormorant uses ducted fans that are effectively shielded
rotors, which means the aircraft does not need to worry about bumping into a
wall and damaging the rotors. Another set of fans propels the vehicle forward.
The vehicle is effectively a decision-making system that can figure out what to
do if there is a problem in the inputs from the sensors, the company, Urban
Aeronautics, said. If the Cormorant detects a potential issue, the drone's
robotic brain can decide whether to go home, land and wait for more
instructions, or try a different flight path.

How
Can Hospitality Brands Maintain Brand Stability
Among the
many inspiring folklores of cross-industry inspiration for customer delight
lies the story of Ritz Carlton and Apple. When Steve Jobs was searching for
ideas to deliver on exceptional guest experience, he didn’t hesitate to borrow
from the anticipatory customer service model of Ritz Carlton and train his
staff as per the hotel’s service standards. Even the prominent Apple Genius bar
is inspired by the concierge station at the hotel that is the first point of
communicating brand stability and building consumer trust in your services.
Herein lies the most important lesson – trends will come and go but
exceptional service standards will never go out of style. Though it
sounds simple, maintaining a consistency in product, message, and service yet
being relevant in the current environment is definitely an uphill task for
hospitality.
The role of
millennials
“We
millennials have been advertised to our entire lives, and we can tell when
somebody is just trying to sell us something”. The future of hospitality is in
the hands of this new age traveler. Being born in a digitally connected world, he
no longer considers free wireless connectivity in a hotel as a luxury. He
is a value seeker and searches for unique experiences instead of a to and fro
trip to a destination. However, once you have him hooked, he is more
likely to remain loyal to you than any other generation. Being born to
helicopter parents, he isn’t really sharing responsibilities at home and will
want to club business travel with personal leisure. So the lines between
business and leisure travel will blur with time. With millennials
contributing 22% of all travelers and 200 billion USD annual revenue, the
hospitality industry has to be quick to respond to the opportunities and
risks posed by this new consumer segment
The balance
between standardization and localization
Such content
is a rich repository of information for a brand to evaluate its consistency at
all its touchpoints and across geographical locations. A Starwood hotel in
Chennai cannot afford to have its brand loyalist guest comment on the staff not
greeting him while he walked down the hotel corridors. This standardization,
whether in people, products or processes, is no more just desired from luxury
hotel chains like Marriott and InterContinental Hotel Group but also in the
budget segment like AirBnB and OYO rooms. This is where marketing and
operations team have to align so that each employee understands his part in the
brand delivery chain. The Hilton’s campaign depicting an iron-clad satisfaction
guarantee inspiring staff to solve problems “on the spot” is a good illustration
for the same.
However,
isolation from the environment you operate in is never ideal. Today’s traveler
expects a hospitality brand to be a part of the experience he expects from the
destination. With expansion in the managed and franchise properties across
locations, it is vital to maintaining this balance between standardization and
local flavor. If you are traveling from India to China, you would probably want
to see hotel listings in English or Hindi. If booking details are available to
you in the translated version, you may expect that the host knows your language
as well but that might not be true. To prevent such expectation performance
mismatch, AirBnB shows listings in the local language with an optional
translate button. Minute details like these go a long way in delivering a truly
global experience.
A framework
to leverage user based content
This is the
generation of user based content and it is more of an opportunity than a threat
for building your brand. 88% of people worldwide trust an online review as much
as a personal recommendation. Fear of fake/dishonest reviews submitted by
customers diluting your brand is valid. But the way to deal with it is to
enable listening ports across the customer life cycle. Exceptional service
standards have a contagious effect. If there’s enough zeal in employees to make
a guest’s stay the best he ever had, the energy will pass on to him to share a
positive review about you in his network.Assessment of guest needs through data
intelligence, benchmarking processes against the best in the industry and
reflecting on guest feedback to improve products/services, has to be a standard
imbibed in the culture of the organization. A platform to derive actionable
inputs from the plethora of content available about customers will aid the
organization in this process. The next desired improvement in your service, a
new product idea or brand pitch will not come from the million dollar
consultant but the guest who knows the market better than anyone else.
Serendipity is what the millennial seeks. The hospitality industry can turn
this opportunity into revenue only when they know more about such travelers and
can drive this traffic to directly interact with the hotel than shop around in
the marketplace.Hospitality brands must not hesitate to learn continuously how
they made their customers feel. Using this understanding to build a scalable
yet reliable model is what will earn customer trust and brand stability. Making
people happy is not an art but a part of your soul. Imbibe this across the
service delivery chain – be it technology or management – and you will lead
till the end of time.
How Working Remotely Is
Helping Women Close the Gender Gap In Tech
It is no secret that I am a big
advocate for remote teams. Since launching my startup in Bali, I have hired top
talent from all over the world to help build Mailbird into what it is today. While
many companies are starting to realize the benefits of remote work, it is still
a work structure that has yet to be embraced by the masses. However, for women,
the ability to work from home runs much deeper than a reduced commute time and
increased productivity. Remote work is a chance for the tech industry to close
its infamous gender gap. The Problem with the Gender Gap
in Tech These days, everyone seems to
have their own reasons for the gender imbalance in tech. Some argue that tech
companies have male-centric cultures and as a result hire men over women
regardless of skills and aptitude. Katharine Zaleski, a founder of PowerToFly,
a remote work job site for women, has a different theory. She believes that the
reason there aren't more women in tech is that companies are not giving women,
especially mothers, the flexibility they need to pursue their career and raise
a family at the same time.
Let’s Look At the Cold Hard
Facts
The lack of flexibility in the
workplace is not a new theory in the gender gap studies. According to Pew
Research Center, 51 percent of women said being a working mother made it harder
for them to advance their careers while only 16% percent of fathers felt the
same way. The same study also found that 42 percent of mothers reduced their
work hours to make time for their growing families while just 28% of fathers
said the same. This claim is further supported by the National Center for Women
& Information Technology. Their report found that as many as 56% of women
leave their tech jobs mid-career. Another study by the University of
Wisconsin-Milwaukee also found that one-third of women surveyed had left the
tech industry because companies were not flexible enough to accommodate an
adequate work-life balance. With statistics like these, I think it is safe to
say the problem with the gender imbalance in tech does not lie within the lack
of female candidates or male-centric office cultures. It lies with companies
holding on to archaic working environments. By continuing to vouch for a
structure that impacts a women's career prospects and financial well-being, it
affects the economy as a whole. The fewer women in tech means more jobs will go
unfulfilled and this will spur stagnation in innovation and global
competitiveness.
The Solution: A Flexible
Working Environment
The inclusion of women in the
workforce has changed how we work. It has made women feel pressured into
choosing between their careers or families. As a result, our working
environments need to change, and remote work is a viable option. Companies need
to adapt and change their structures to give employees a healthy work-life
balance especially if they want to keep retention rates high. A 2017 study by
professional recruiter Robert Walters and leading UK job board Jobsite found
that remote working opportunities are top priorities for women in tech. 76% of
women surveyed said that the chance to work remotely was necessary if companies
wanted to retain long term staff.
Use of Plastic Material in Road
Construction
Plastic material is a synthetic
or semi-synthetic organic solids that are mountable. Plastics are typically
organic polymers of high molecular mass. The use of plastic and related
materials is increasing tremendously due to growth in population, urbanization
and modern life style. Municipal solid waste in India contain 1-4 per cent by
weight of plastic waste. India’s rate of recycling of plastic waste is the
highest (60%) in the world as compared to other countries (China 10%, Europe
7%, Japan 12%, South Africa 16%, USA 10%). As a source of hazard to
environment, plastic account for 16% of chlorine in the environment and have 54
carcinogens, polythene bags for disposal if burnt irresponsibly releases highly
toxic gases like phosgene, carbon monoxide, chlorine, sulphur dioxide, nitrogen
oxide, besides deadly dioxin. India generates 56 lakhtonnes of plastic waste
annually, with Delhi accounting for a staggering 689.5 tonnes a day.
"Total plastic waste which is collected and recycled in the country is
estimated to be 9,205 tonnes per day (approximately 60% of total plastic waste)
and 6,137 tonnes remain uncollected and littered. Wastes plastics are not
disposed scientifically due to their non-biodegradability hence the disposal of
waste plastic is now become a very big global problem. Recently these waste
plastic material is used as additives in road construction. Generally bitumen
is used as binder in road construction and binding capacity of this bitumen is
low but when plastic waste is mixed with hot bitumen and the resulted mix is
used for road construction increase binding capacity of bitumen. The use of
this innovative technology will not only strengthen the road construction but
also increase the road life as well as will help to improve the environment.
Plastic roads would be a boon for India's hot and extremely humid climate,
where temperatures frequently cross 50°C and torrential rains create havoc,
leaving most of the roads with big potholes. Dr. R. Vasudevan, Dean and Head of
the Chemistry Department of the Thiagarajar College of Engineering (TCE) The
man behind this mission is known as Madurai's 'Plastic Road Man'.The first ever
plastic road (60 feet long) was laid inside the TCE campus in 2002, followed by
a 700 m road in Lenin Nagar, Kovilpatti, the same year. Officially, the
industrial town of Salem was the first in the country to lay a 350 m road on an
experimental basis using plastic tar technology in 2004.

inaugurating the 5th Foundation Day of Biotechnology Industry Research
Assistance Council (BIRAC), Department of Bio-Technology at New Delhi today. Mr.
Y. S. Chowdary, further said that – “Research and innovation has been one of
the key areas emphasized by the Prime Minister. Globally, BIRAC has been hailed
as one of the most effective government measures to create an enabling
environment for research and development to flourish in a country. We aim to
develop India into a global innovation hub by 2020 and BIRAC has paved the way
to deliver on that mandate.” The 5th Foundation Day themed ‘Impacting the
Biotech Innovation Ecosystem’ was presided over by and attended by a large
number of dignitaries from the scientific and industry sectors both from within
the country and oversees. BIRAC is a not-for-profit public sector enterprise,
set up by the Department of Biotechnology (DBT), Government of India which acts
as an interface agency to support emerging biotech enterprises to undertake
strategic research and innovation, to address nationally relevant product
development needs. Through the course of five years, BIRAC has supported over
618 projects, 850 start-ups, entrepreneurs, biotech companies and organizations
and 20 incubators across the country, resulting in over 66 products and
technologies and 120 Intellectual property rights being generated. BIRAC
supports entrepreneurs and start-ups at different stages of innovation – from
the ideation stage to managing intellectual property rights and finally to the
commercialization of products. Different initiatives of BIRAC target different
stages of the innovation ecosystem from ideation stages to proof-of-concept and
late stage validation to product development. BIRAC has 9 flagship schemes that
are supported by funding from the Department of Biotechnology, and manages 7
collaboratively funded programs with international partners, such as the Bill
& Melinda Gates Foundation, Nesta, the Wellcome Trust and USAID, among
others. Social Innovation is a key focus for affordable and accessible product
development. Dr. K. Vijay Raghavan, Secretary, Department of Biotechnology and
Chairman, BIRAC said that Innovation and research must be directed toward
addressing the most pressing problems of society. We’re proud that BIRAC and
the Department of Biotechnology are spearheading this effort in the
biotechnology domain. Since its inception in 2012, BIRAC has created nearly two
dozen incubators across the country and supported over 350 start-ups. We firmly
believe that social entrepreneurship is the key to creating an inclusive
society and our government is committed to providing all the necessary support.
The science and technology sector will play a key role in the government’s
Start-Up India Action Plan. The DBT, in line with the Start-Up India Action
Plan has undertaken a number of initiatives centered on the three pillars of an
ideal innovation ecosystem – funding, mentoring and capacity building, and the
infrastructure to translate scientific research into commercial products. To
this end, BIRAC implements its mandate through a wide range of high impact
initiatives, providing access to risk capital through targeted funding,
facilitating technology transfer, and supporting intellectual property
management and handholding schemes for biotech firms to make them globally
competitive. Dr. Renu Swarup, Senior Adviser,

Second 'Great Spot' found at Jupiter,
cold and high up
CAPE CANAVERAL: Another "Great Spot'' has been found at
Jupiter, this one cold and high up. Scientists reported Tuesday that the dark
expanse is 15,000 miles (24,000 kilometers) across and 7,500 miles (12,000
kilometers) wide. It's in the upper atmosphere and much cooler than the hot
surroundings, thus the name Great Cold Spot. And unlike the giant planet's
familiar Great Red Spot, this newly discovered weather system is continually
changing in shape and size. It's formed by the energy from Jupiter's polar
auroras. A British-led team used a telescope in Chile to chart the temperature
and density of Jupiter's atmosphere. When the researchers compared the data
with thousands of images taken in years past by a telescope in Hawaii, the
Great Cold Spot stood out. It could be thousands of years old. "The Great
Cold Spot is much more volatile than the slowly changing Great Red Spot ... but
it has reappeared for as long as we have data to search for it, for over 15
years,'' the University of Leicester's Tom Stallard, lead author of the study,
said in a statement. tallard said Jupiter's upper atmosphere may hold
other features. Scientists will be on the lookout for them while also studying
the Great Cold Spot in greater detail, using ground telescopes as well as
NASA's Juno spacecraft in orbit around Jupiter, he said. The study was
published in Geophysical Research Letters, a journal of the American
Geophysical Union.

Carbon nanotubes self-assemble into
tiny transistors
Carbon nanotubes can be used to
make very small electronic devices, but they are difficult to handle.
University of Groningen scientists, together with colleagues from the
University of Wuppertal and IBM Zurich, have developed a method to select
semiconducting nanotubes from a solution and make them self-assemble on a
circuit of gold electrodes. The results were published in the journal Advanced
Materials on 5 April. The results look deceptively simple: a self-assembled
transistor with nearly 100 percent purity and very high electron mobility. But
it took ten years to get there. University of Groningen Professor of
Photophysics and Optoelectronics Maria Antonietta Loi designed polymers which
wrap themselves around specific carbon nanotubes in a solution of mixed tubes.
Thiol side chains on the polymer bind the tubes to the gold electrodes,
creating the resultant transistor.
Patent
'In our previous work, we learned
a lot about how polymers attach to specific carbon nanotubes', Loi explains.
These nanotubes can be depicted as a rolled sheet of graphene, the
two-dimensional form of carbon. 'Depending on the way the sheets are rolled up,
they have properties ranging from semiconductor to semi-metallic to metallic.'
Only the semiconductor tubes can be used to fabricate transistors, but the
production process always results in a mixture. 'We had the idea of using
polymers with thiol side chains some time ago', says Loi. The idea was that as
sulphur binds to metals, it will direct polymer-wrapped nanotubes towards gold
electrodes. While Loi was working on the problem, IBM even patented the
concept. 'But there was a big problem in the IBM work: the polymers with thiols
also attached to metallic nanotubes and included them in the transistors, which
ruined them.'
Solution
Loi's solution was to reduce the
thiol content of the polymers, with the assistance of polymer chemists from the
University of Wuppertal. 'What we have now shown is that this concept of
bottom-up assembly works: by using polymers with a low concentration of thiols,
we can selectively bring semiconducting nanotubes from a solution onto a
circuit.' The sulphur-gold bond is strong, so the nanotubes are firmly fixed:
enough even to stay there after sonication of the transistor in organic
solvents. The production process is simple: metallic patterns are deposited on
a carrier , which is then dipped into a solution of carbon nanotubes. The
electrodes are spaced to achieve proper alignment: 'The tubes are some 500
nanometres long, and we placed the electrodes for the transistors at intervals
of 300 nanometres. The next transistor is over 500 nanometres away.' The
spacing limits the density of the transistors, but Loi is confident that this
could be increased with clever engineering. Over the last years, we have
created a library of polymers that select semiconducting nanotubes and
developed a better understanding of how the structure and composition of the
polymers influences which carbon nanotubes they select', says Loi. The result
is a cheap and scalable production method for nanotube electronics. So what is
the future for this technology? Loi: 'It is difficult to predict whether the
industry will develop this idea, but we are working on improvements, and this
will eventually bring the idea closer to the market.'

Next-generation
steel and metal alloys are a step closer to reality, thanks to an international
research project involving a University of Queensland scientist.
The work could overcome the problem of hydrogen alloy
embrittlement that has led to catastrophic failures in major engineering and
building projects. UQ Centre for Microscopy and Microanalysis Director
Professor Roger Wepf said the problem had been recognised for almost 140 years.
"The current generation of these metals can suffer hydrogen embrittlement,
where they become brittle and fracture due to the accidental introduction of
hydrogen during manufacture and processing," he said. "A major
example of alloy embrittlement occurred in 2013, when bolts in the eastern span
of the San Francisco-Oakland bridge failed tests during construction." Professor
Wepf said hydrogen was extremely volatile and diffused quickly. "Our
research collaboration has, for the first time, localised and visualised
hydrogen in steels and alloys," he said. "This is essential for the
development of new alloys with greater endurance." "We have shown
that it's possible to localise hydrogen at atomic resolution -- at the scale of
a single atom -- or at a nanometre (less than one-billionth of a metre) scale
by combining different technologies in a closed and protected workflow. "These
include state-of-the-art cryo electron microscopy freezing techniques,
low-temperature sample preparation in a cryo focused ion beam microscope, and
inert cryo-transfer.

Maharashtra Developing App for Black and Yellow Taxis:
Fadnavis
The Maharashtra government is in the
process of developing and launching a cab hailing app within three months for
black and yellow taxis on the lines of those provided by private aggregators
like Ola and Uber, Chief Minister Devendra Fadnavis said on Friday. He was
responding to a query raised by Leader of Opposition Dhananjay Munde, Hemant
Takle (NCP) and others in the State Legislative Council in Mumbai. Raising the
issue during the Question Hour, Takle said that after app-based cab aggregators
came into the picture, the business of black and yellow taxi drivers has gone
down considerably and he questioned if the government will take steps to ensure
they survive the fierce competition. Responding to him, State Transport
Minister Diwakar Raote said the government has brought an ordinance of City
Taxi Service Control Rules and that suggestions of 6,000 people have taken into
account on the issue. Leader of Opposition Dhananjay Munde said that Ola and
Uber enable users to track locations besides providing easy services. "When
will the government bring in such an App for black and yellow taxis ?" he
questioned. To this, Fadnavis said, "the government is in the process of
developing an electronic platform for black and yellow taxis similar to that of
cab aggregators. It will provide services similar to those given by cab
aggregators. This app will be launched in three months." Earlier, Kiran
Pawaskar (NCP) pointed out that cab aggregators have survived across the world
due to the low costs they charge customers, cleanliness and manners their cabs
and drivers have and facilities of tracking they provide to customers. "On
the other hand, black and yellow taxi drivers do not wear uniforms, do not
behave properly and blatantly refuse to ferry customers. They do not provide
proper service and hold people to ransom anytime. Will they be asked to adhere
to rules," he questioned. Responding to Pawaskar, Raote had said that black
and yellow taxi drivers will themselves have to deal with issues like
mannerisms and cleanliness to increase business and survive competition and
that taxi unions can help them with these issues. "Also, the government is
mulling to provide AC services to customers of black and yellow taxi drivers
who have taken a new car to bring them at par with Ola and Uber," Raote
said.

Facebook, WhatsApp to be regulated, DoT tells Supreme Court
NEW DELHI: The Centre informed the Supreme Court on Wednesday that it would soon formulate a regulatory regime, similar to one existing for all telecom operators, for Over-The-Top (OTT) services like WhatsApp, Facebook, Skype, WeChat and Google Talk. The department of telecom's main argument was that OTTs use the network of telecom service providers to reach customers, offer App-based products as well as compete by offering messaging and telephone facilities, yet are not subjected to any regulatory mechanism.
This assertion came in response to WhatsApp's affidavit in the SC taking a stand that the petition filed by Karmanya Singh Sareen questioning its privacy policy was not maintainable as "OTT services are governed in some respect by the provisions of Information Technology Act, 2000 and are not subject to the same regulatory mechanism that is enforced on conventional voice and messaging services provided by telecom service providers".
With the privacy issue being strongly argued by the petitioner and the Centre converging on it, the bench referred the issue to a five-judge bench, despite opposition from OTT service providers. It fixed April 18 for hearing before the five-judge bench for fixing dates for final disposal of the petitions even as a request was made that it should not be heard during the summer vacation.

NASA plans to build Moon-orbiting spaceport
The period of exploration in the vicinity of the Moon will begin with the first integrated mission of the Space Launch System (SLS) rocket and the Orion spacecraft. NASA is planning to establish a crewed spaceport near the Moon that could serve as a gateway to the lunar surface and deep space destinations including Mars. The area of space near the Moon offers a true deep space environment to gain experience for human missions that push farther into the solar system, access the lunar surface for robotic missions but with the ability to return to Earth if needed in days rather than weeks or months, NASA said. The period of exploration in the vicinity of the Moon will begin with the first integrated mission of the Space Launch System (SLS) rocket and the Orion spacecraft, it said. The agency is looking to build a crew tended spaceport in lunar orbit within the first few missions that would serve as a gateway to deep space and the lunar surface. This deep space gateway would have a power bus, a small habitat to extend crew time, docking capability, an airlock, and serviced by logistics modules to enable research.
The propulsion system on the gateway mainly uses high power electric propulsion for station keeping and the ability to transfer among a family of orbits in the lunar vicinity.The three primary elements of the gateway, the power and propulsion bus and habitat module, and a small logistics module(s) would take advantage of the cargo capacity of SLS and crewed deep space capability of Orion.
An airlock can further augment the capabilities of the gateway and can fly on a subsequent exploration mission. "The gateway could move to support robotic or partner missions to the surface of the Moon, or to a high lunar orbit to support missions departing from the gateway to other destinations in the solar system," said William Gerstenmaier, associate administrator for Human Exploration and Operations at NASA.
The second phase of missions will confirm that the agency's capabilities built for humans can perform long duration missions beyond the Moon. For those destinations farther into the solar system, including Mars, NASA envisions a deep space transport spacecraft. This spacecraft would be a reusable vehicle that uses electric and chemical propulsion and would be specifically designed for crewed missions to destinations such as Mars. The transport would take the crew out to their destination, return them back to the gateway, where it can be serviced and sent out again.

Next-generation steel and metal alloys are a step closer to reality, thanks to an international research project involving a University of Queensland scientist.
The work could overcome the problem of hydrogen alloy embrittlement that has led to catastrophic failures in major engineering and building projects. UQ Centre for Microscopy and Microanalysis Director Professor Roger Wepf said the problem had been recognised for almost 140 years. "The current generation of these metals can suffer hydrogen embrittlement, where they become brittle and fracture due to the accidental introduction of hydrogen during manufacture and processing," he said. "A major example of alloy embrittlement occurred in 2013, when bolts in the eastern span of the San Francisco-Oakland bridge failed tests during construction." Professor Wepf said hydrogen was extremely volatile and diffused quickly. "Our research collaboration has, for the first time, localised and visualised hydrogen in steels and alloys," he said. "This is essential for the development of new alloys with greater endurance." "We have shown that it's possible to localise hydrogen at atomic resolution -- at the scale of a single atom -- or at a nanometre (less than one-billionth of a metre) scale by combining different technologies in a closed and protected workflow. "These include state-of-the-art cryo electron microscopy freezing techniques, low-temperature sample preparation in a cryo focused ion beam microscope, and inert cryo-transfer.

Last minute tips for JEE(Main)
With the Joint Entrance Exam (Main ) in just 5 days, students are geared up for the big day. The remaining days would be filled with panic and distraught among students, so it is essential to work level-headedly. Although, each year JEE(main) exams have a stiff competition, but self confidence is the key to sail through the storm. Here are few tips to excel your exams
Do not start with new topics: There are chances that you have overlooked a few topics in the process of revision. However, it is recommended to not start anything new and clear doubts of already prepared topics, instead. There is a high possibility that starting with something new can confuse you and hence can lead to baffling the existing concepts.
Mock Tests are essential: With ongoing revisions, make sure to dedicate time in solving mock test papers. This not only helps in improving efficiency of attempting questions but helps in time management. Constant practice of mock tests takes you through the entire syllabus at least once in a day, hence allowing you to focus on every concept.
Try sticking to NCERT books: Stay focussed on the NCERT books and don't take up too many reference books. The major portion of the exam is covered from the NCERT. This forms the basic foundation for you, hence at this point of time it is vital to stick to NCERT study material and strengthen your concepts.
Keep your happiness at priority: Do not stress yourself unnecessarily. If you're well prepared and confident enough, make sure you don't panic. To stay stress free make sure you take out time for to rejuvenate yourself, take regular short breaks and try to do what you like. Listen to your favourite music, dance on your favourite number, and spend time with family. This will keep your mood uplifted and give positive vibes.
Stay Healthy to concentrate well: At this time your health plays a very important part in your success.Try to take a morning walk, it is a best way to start your day. No matter how stressed you're make sure to go outdoors once in a day. Prefer home cooked green veggies, and take small and regular interval. Get adequate sleep; ensure 6-7 hours of sleep every day.
Study Solo in your last days: This is not a very good time to prefer group studies; Group studies at the last minute can increase anxiety and pre-exam jitters. Take up controlled practice of mock tests.
Pro Tip: Not all sections carry equal weightage, Give time to the topics as per their weightage in the examination.
