The brain is considered as the most complex organ, able to store and access huge data, and can even analyze, manipulate and draw from these memories. But how does the brain store all that information? Commonly held theories suggest, experiences cause neurons in the brain to fire and strengthen connections, while brain cells called engrams encode specific memories. They do this by triggering coordinated activity that represent a memory,in a set of these cells, helping in recalling a memory. In this new study, scientists show that engram cells can actually be identified.

The story of the river Saraswati has captivated scholars and academicians alike. With no physical evidence, the memory of the extinct river has survived centuries, starting from its first mention in the Rigveda, through poems and stories. The river is said to have originated in the Himalayas and emptied in the Arabian sea near present day, Rann of Kachchh. Now a new study in the Rann of Kachchh has revealed some interesting evidence which could help us establish the story of Saraswati as myth or fact.

White blood cells (WBC), on the other hand, are the bodies primary defense system. Produced in the bone marrow, WBC helps the body fight invaders, like virus and bacteria.

In 1959, Luna 1, a Soviet Union mission to the moon, successfully landed on the surface of the moon, kickstarting the space race between America and the Soviet that lasted for decades. Today, many countries are looking beyond our moon, and at moons of other planets like Jupiter and Saturn. Although, twelve astronauts have walked on its surface, manned missions to the moon came to a close in 1972. But the urge to study our closest neighbor never receded.
