R-77 reaches a maximum engagement range of approximately 100 kilometers, which is much shorter than the 300-400 kilometers of the R-37M.

 

The R-77 is capable of reaching Mach 4-5 and the R-37M capable of reaching Mach 6.

 

BrahMos NG Cruise Missile

 

The development of the BrahMos NG (Next Generation) system of missiles is on early stages in India.

 

BrahMos NG is a smoother missile that has the same features as its predecessor.

 

The much lighter, smaller and compact Bhrahmos NG will fit to be mounted on the Russian-made Sukhoi-30MKI fighter and locally made Light Combat Aircraft Tejas.

 

The range of the missile is 290 km and the speed is up to 3.5 Mach.

 

Indonesia will be the second foreign purchaser of the missile systems after Philippines.

 

Reimei computer

 

In Japan, the 20-qubit quantum computer named Reimei is a part of the Fugaku.

 

The Fugaku is the sixth-fastest supercomputer in the world.

 

It is the first fully functional hybrid quantum supercomputer, which is a combination of.

 

F11 Bacteria

 

One research team has found a variety of bacteria that are able to break down and convert at least three forms of PFAS.

 

It is interesting to note that this strain is also able to break down some of the toxic byproducts formed in the breakdown process.

 

Over 100 days, the bacterium Labrys portucalensis F11 (F11) metabolised over 90% of perfluoro octane sulfonic acid (PFOS).

 

PFOS is among the most common and long-lasting PFAS, and was declared as a hazardous substance by the U.S. Environmental Protection Agency in 2022.

 

The bacteria F11 were first extracted in the polluted industrial soil in Portugal.

 

 

The first-ever cross-blood kidney transplant.

 

Doctors at MIOT International in Chennai, performed a cross-blood Transplant on patient with rare Bombay blood group.

 

Team of MIOT Hospitals a successfully employed O blood group recipient with the kidney of B blood group donor in 2010.

 

They have applied special procedure known as double filtration plasmapheresis (DFPP) developed in Japan.

 

The Bombay a.k.a. HH blood group is a rare blood group that was first identified in Mumbai in 1952 by Y.M. Bhende.

 

The major variation between the Bombay blood group and the common ABO blood groups is the presence (or absence) of the H antigen.

 

Such individuals are unable to get blood transfusion of any ABO group, even type O which carries the H antigen.

 

They are only able to take blood of another Bombay blood group donor.

 

It occurs in approximately 0.0004 percent (one in every 4 million) of the entire human population.

 

This was the first cross-blood kidney transplant.

 

In patient with rare Bombay blood group, Doctors at MIOT International in Chennai, performed a cross-blood transplant.

 

In 2010, team of MIOT Hospitals a successfully transplanted the kidney of a donor with B blood group onto a recipient with O blood group.

 

They have employed special procedure known as double filtration plasmapheresis (DFPP) invented by Japanese.

 

The Bombay, also called HH, blood group is a rare blood group that was initially identified in Mumbai in 1952 by Y.M. Bhende.

 

The major variations of the Bombay blood group and the ubiquitous ABO blood groups, are the presence (or absence) of the H antigen.

 

These individuals are not able to be transfused with blood of any ABO group, not even with type O that contains the H antigen.

 

Only another Bombay blood group donor can give her blood.

 

It is estimated at 0.0004% (one in 4 million) of the entire human population.

 

Earth's Inner Core Dynamics

 

The recent researches have shown some evidence of the inner core of the earth deforming at its boundary with the outer liquid core.

 

The independent spin of the inner core seems to be slowing down.

 

The center is a hot, largely solid ball of iron approximately 1,500 miles in width.

 

These results are indicative that the structural changes are taking place on the near surface of the inner core.

 

These alterations may interfere with its rotation and even have an impact on the duration of a day.

 

The dynamic between the inner and outer core is said to be the engine that drives those developments.

 

Gravehawk System

 

Ukraine is also said to have acquired a new weapon - the Gravehawk hybrid surface-to-air missile system.

 

This system was invented by the United Kingdom with
