Scientists have found a new,
cheaper and easier way to manufacture solar cells, which could challenge the
domination of silicon. An alternative material called Perovskite is more
efficient and adaptable than previous thought, scientists said. “The challenge
to developing efficient and cheap commercially available solar panels has,
until now, been dominated by silicon, with emerging alternative solar cells
considered minor players,” said Lin Leong from Institute of Materials Research
and Engineering in Singapore. Perovskite is relatively easy to process, and
therefore cheaper to manufacture, but also has an efficiency of 22%, close to
silicon cells 25%.

Most sensitive detector fails to find dark matter
The world’s most sensitive dark
matter detector has failed to yield any trace of the elusive substance thought
to account for more than four-fifths of the mass of the universe, even after 20
months of operation. The Large Underground Xenon (LUX) dark matter experiment,
which operates beneath a mile of rock at the Sanford Underground Research
Facility in the Black Hills of South Dakota, has completed its silent search
for the missing matter of the universe. LUX’s sensitivity far exceeded the
goals for the project, scientists said, but yielded no trace of a dark matter
particle.

ISRO launched Indian Regional Navigation Satellite System-1F
On 10 March 2016, the Indian
Space Research Organisation (ISRO) launched the country’s sixth Indian Regional
Navigational Satellite System (IRNSS)-1F, on board the trusted launch vehicle
PSLV C-32. The lift off took place from the second launch pad of the Satish
Dhawan Space Centre (SDSC) SHAR, Shriharikotta. Satellite IRNSS-1F was launched
after the 54 and a half hour countdown that started on 8 March 2016. XL version
of PSLV was used in PSLV-C32 and ir was the twelfth time that the ‘XL’
configuration was flown.
Ø
The lift off
mass of IRNSS-1F is 1425 kg and the dry mass is 598 kg.
Ø
Its
configuration is similar to that of IRNSS-1A, 1B, 1C, 1D and 1E.
Ø
The two
solar arrays of IRNSS-1F consisting of Ultra Triple Junction solar cells generate
about 1660 watts of electrical power.
Ø
The mission
life of IRNSS-1F is 12 years.
Ø
IRNSS-1F
carried two types of payloads navigation payload and ranging payload. The navigation
payload of IRNSS-1F will transmit navigation service signal to the users.

World's first robot lawyer ROSS hired by US law firm
US-based law firm Baker Hostetler on May 2016 hired the
world’s first robot lawyer ROSS to assist the company and its various teams in
legal research. The law firm will license artificial lawyer ROSS for use in its
Bankruptcy, Restructuring and Creditors Rights team.
Key
Features:
Ø
With the support of Watson’s lawyers can ask
ROSS their research question.
Ø
The ROSS reads through the law, gathers
evidence, draws inferences and returns highly relevant, evidence-based answers.
Ø
ROSS also monitors the law around the clock to
notify user of new court decisions that can affect a case.
Ø
The programme continually learns from lawyers
who use it to bring back better results each time.
UAV flights for early diagnosis of HIV in infants
On 14 March 2016, the Government of Malawi and UNICEF
successfully tested the use of Unmanned Aerial Vehicles (UAVs or drones) to
explore cost effecting ways of reducing waiting times for HIV testing of
infants. As part of the test, simulated blood samples were transported from a community
health centre to the Kamuzu Central Hospital laboratory that is located at a
distance of 10 kilometers. Though drones were used in the past for surveillance
and assessments of disaster, this is the first known use of UAVs in Africa for Improvement
of Human Immunodeficiency Virus (HIV) services. After successful completion of
further tests, the drone services well be integrated into the health system
alongside others existing mechanism such as road, transport and short message
service (SMS).
Significance of UAVs for Malawi
The successful completion of tests and integration of UAVs with HIV services of significance for Malawi due to the following scenario. In 2014, nearly 40000 children in Malawi were born to HIV positive mothers. It is also estimated that around 10000 children deaths occur every year due to the infection. The high incidence of death is attributed to the fact that there is a considerable delay in diagnosis of the infection in infants. This is because of transport challenges and associated delays experienced by health workers in remote areas of the country.

India successfully test fired Agni-1 ballistic missile
On 14 March
2016, India successfully test-fired indigenously built nuclear capable
intermediate range Agni-1 ballistic missile. It was launched from launch pad-4
of the Integrated Test Range (ITR) at Abdul Kalam Island (Wheeler Island) on
the Odisha coast. The trial was as part of training exercise by the Strategic
Force Command (SFC) of Indian Army. The sophisticated missile covered 700 km
distance within 9 minutes and 36 seconds. The latest trial of Agni-1 followed
the first successful test-fire that was conducted on 27 November 2015 from the
same base.
Ø
Agni-1 was developed by Advanced System
Laboratory, the premier missile development laboratory of DRDO in collaboration
with Defence Research Development Laboratory and Research Centre Imarat and
integrated by Bharat Dynamics Limited, Hyderabad.
Ø
The missile is 15-metre long and weighed 12
tonnes and equipped with sophisticated navigation system which ensures it
reaches the target with a high degree of accuracy and precision.
The missile is a surface-to- surface and
single-stage missile powered by solid propellant and capable of hitting a
target 700 kilometers away
