Cells that Can Destroy Leukemia developed
by US Scientists
U.S. scientists developed cells that can
destroy leukemia in three weeks
That could lead to new and effective
treatments for deadly blood cancer
A new engineering technique involving
leukemia patients treated with their own
T cells
T cells: A type of white blood cells that
were genetically modified to target and
destroy tumors within the patient’s
body
White blood cells are unable to
distinguish tumor cells from healthy tissue,
allowing cancer to spread out of
control
To overcome this problem, scientists
inserted a protein called chimeric antigen
receptor on white blood cells so that they can
attack tumor cells
Inserted protein will bind with
another protein called CD19 that is present in
Leukemia tumour cells
This results in the proliferation of T
cells

India’s desert State Rajasthan’s
First-ever Export of Certified Organic Food to the US
The first-ever consignment of certified
organic food to be exported from Rajasthan
to the United States
The organic food comprised mainly
conventional pulses for which there is a
heavy demand in the U.S.
The pulses were produced from the
processing unit of the Morarka
Organic
Foods in Sitapura Industrial Area
Organic farming culture gaining ground
in Rajasthan is deemed to be as
significant as Harit Kranti (Green
Revolution) introduced in 1965 by the then
Prime Minister Lal Bahadur Shastri, as a
result of which the wheat imports from
the U.S. had stopped
TrES-2b (or Kepler-1b): Coal-Black Alien
Planet Is Darkest Ever Seen
TrES-2b (or Kepler-1b): An extrasolar planet orbiting the
star GSC 03549-02811 located 750 light years away
The planet has been identified in 2011
as the darkest known
exoplanet, reflecting less than 1% of
sunlight
It is darker than any planet or moon in
our solar system
NASA’s Kepler spacecraft was used by the
astronomers to make
this observation
TrES-2b was discovered in 2006 by the
Trans-Atlantic Exoplanet
Survey
It orbits its star at a distance of only
three million miles. The star heats TrES-2b to
a temperature of more than 1800 degrees
Fahrenheit
TrES-2b orbits the star GSC03549, which is located about 750 light-years
away
It can be observed near the constellation Draco TrES-2b is the
darkest known exoplanet, reflecting less light than coal or black acrylic paint.It
is not clear why the planet is so dark. One reason might be a lack of
reflective clouds like those that make brilliant Jupiter, due to the proximity
TrES-2b to its parent star and therefore high temperature. Another reason could
be the presence in the atmosphere of chemicals that absorb light such as sodium
vaporized titanium oxide or potassium gas.
‘Citizens have right to invoke RTI Act to
fight corruption’: SC
The Supreme Court articulated that the
Citizens have a right to invoke the RTI Act
to fight corruption and bring in
transparency and accountability in the
administration
A bench of justices R V Raveendran and
A.K. Patnaik opined that the provisions of
RTI Act should be enforced firmly and all
pains should be made to bring to light
the necessary information under clause (b)
of section 4(1) of the Act which relates
to securing transparency and
accountability in the working of public authorities
and in discouraging corruption
The bench made the remarks while
dismissing the Central Board of Secondary
Education’s plea that Students have no
right to examine their assessed answer
scripts
The apex court however, said that the Act
should not be misused for extracting
impractical information in an
indiscriminate manner
IOC launches multi-function regulators
for LPG cylinders
State-owned Indian Oil Corp (IOC) launched multi-function regulators for
domestic cooking gas cylinders
The Multi-functional domestic presser
regulator has numerous safety features
which include leak detection, child lock,
gas level indicator and excess flow shutoff
feature
The safety features of the regulator will
be helpful in making kitchens safe and
convenient
