|INDIAN STANDARD TIME AND ATOMIC CLOCKS
India is planning to legalise Indian Standard Time

time sourced from US-based Network Time Protocol. Once IST becomes legal, users will not be allowed to
use any other time other than the one generated by National Physical Laboratory
ü Other elements used to make atomic clocks are:
o Rubidium (Lower cost but less stable),
o Hydrogen masers (short-term stability and low long-term accuracy),
o Mercury ions,
o Isotope of Ytterbium and Strontium
|Who maintains Indian Standard Time?
ü National Physical Laboratory in Delhi, also known as National Measurement Institute
ü The Time and Frequency Standards Laboratory at the institute in New Delhi generate official time signals for both commercial and official use.
ü The signals, based on atomic clocks, synchronize with the worldwide system of clocks that support the Coordinated Universal Time.
üa kind of clock that uses an atomic resonance frequency standard
übased on the properties of atoms transitioning between different energy states.
ü The oscillation frequencies within the atom depend on the mass of the nucleus and the gravity and
electrostatic “spring” between the positive charge on the nucleus and the electron cloud around it.
ü The most accurate atomic clocks available today use the cesium atom and normal magnetic fields and detectors.
ü Cesium 133
ü Inside a cesium atomic clock, cesium atoms are funneled down a tube where they pass through radio waves. When these atoms at resonate frequency, they change their energy state.

· It was dark and faint, with no visible „coma‟ (atmosphere of dust and gas around a comet‟score) or „tail‟ (elongated cloud that points away from the Sun) signature identifiers of comets as they approach the inner Solar System
Oumuamua differs from other comets?
· The dust grains have to be larger than typical for other Comets, which could be a reason for the absence of the characteristic cometary tail.
· The tail we see in comets is typically made of fine dust lifted off the nucleus and dragged away by the emitted gas.
· In the case of „Oumuamua, the dust is not visible because it‟s made of larger grains, that are too heavy to be lifted off by the gas.
· The gas itself is actually very difficult to detect, because the specific molecules composing it (water, CO and CO2) are difficult to see in optical images

ü They need to be cooled to very low temperatures, which restrict their use in our everyday life.
ü The ability to achieve superconductivity at ambient temperature and pressure therefore becomes very significant.

|CRISPR-CAS9 stands for Clustered Regularly Interspaced Short Palindromic Repeat.

|TOTAL LUNAR ECLIPSE totality duration of 1 hour 43 minutes. The duration
makes it the longest total lunar eclipse of this century (2001 AD to 2100 AD)
ü Earth’s shadow can be divided into three parts:
o Umbra – the darker, central part.
o Penumbra – the outer part.
o Antumbra – the partly shaded area beyond the umbra
|Total Lunar Eclipse
ü A total lunar eclipse takes place when the Earth comes between the Sun and the Moon and covers the Moon with its shadow.
ü When this happens, the Moon can turn red– Blood Moon.
ü Total eclipses of the Moon happen at Full Moon when the Sun, Earth, and Moon are aligned to form line- alignment is syzygy
ü When the Sun, Earth, and Moon come together in a straight line, a total lunar eclipse takes place.
ü When the three bodies are aligned in a way that the Moon is partly covered by the Earth’s umbra, a partial lunar eclipse is the result.
ü On the other hand, if only the outer part of Earth’s shadow covers the Moon, a penumbral lunar eclipse takes place.
ü Earth’s umbra extends into space far beyond the orbit of the moon. This means that Earth’s Antumbra plays no role in lunar eclipses
Moon Looks Red?
ü Even though Earth blocks sunlight from directly reaching the surface of the Moon during a total lunar eclipse, the Moon is still visible to the naked eye.
because Earth’s atmosphere bends sunlight and indirectly lights up the Moon’s surface.
ü When sunlight passes through the Earth’s atmosphere, it gets refracted towards the Earth’s surface, and part of it—the colors with shorter wavelengths—gets scattered and filtered out, while
the rest, colors with longer wavelengths like orange and red, passes through the atmosphere.
ü This light is once again refracted towards the surface of the fully eclipsed Moon, thus illuminating it in a reddish-orange glow.
ü Because of this, a total lunar eclipse is sometimes colloquially called a Blood Moon

|BABIES FROM SAME-SEX MICE PAIR AND IMPRINTED GENES
|A team of researchers has produced viable offspring from same-sex pairs of mice, using a novel technology that involves stem cells altered to remove certain genes.
ü Imprinted genes
o During the reproduction process, mammals mostly inherit two sets of each gene, one from their mother and one from their father.
o Imprinted Genes are a small subset of genes, which are inherited from only one parent.
o For these genes, the set produced by the other parent is effectively inactive, having been “shut off” when it is transmitted.
o If this “shutting off” process does not function correctly, the offspring could suffer from abnormalities or even die.
ü Example of Normal inheritance
o If a child inherits the gene for blood group A from either parent and the gene for group B from the other parent, the child’s blood group will be AB.

breeding. However, the rose is more mauve-coloured than blue.
How was the feat achieved?
ü two bacterial enzymes that together can convert L-glutamine, a common constituent of rose petals, into the blue pigment indigoidine.
ü When the researchers injected the engineered bacteria into a white rose petal, the bacteria transferred the pigment-producing genes to the rose genome, and a blue colour spread from the injection site
