We have all heard of the Indus Valley Civilisation.It is well known for its granaries, drainage systems and systematically planned cities like Harappa and Mohenjodaro. However, not much is known about its rise and fall; although there are various theories. In a pair of new studies published in the journals Science and Cell, a consortium of international researchers, including those from India, have tried to decipher the origins of present-day Central and South Asian people. They have used recent advances in genetics to extract and analyse genetic material (DNA) from the remains of several ancient populations, including people from the Indus Valley Civilisation.

Visceral leishmaniasis, or kala-azar, is an insidious disease that affects thousands of people every year. This illness can be fatal, if not diagnosed and treated on time. However, despite best efforts, India still lags behind in eliminating this disease completely. A recent study published in the journal PLOS Neglected Tropical Diseases has investigated the factors that lead to the delayed diagnosis and treatment of kala-azar.
In a country that predominantly depends on rain for irrigation, loss of crops due to disruptive weather continues to be a source of distress to farmers, and approaches to make crops tolerant to the vagaries of weather are necessary. In a recent study, researchers have shown that, by modifying particular genes, rice plants can be kept alive through periods of acute salinity in their water supply.
“ಬ್ಲಾಕ್ ಗೋಲ್ಡ್” ಅಥವಾ ಕಪ್ಪು ಚಿನ್ನವೆಂದೇ ಕರೆಯಲಾಗುವ ಮೆಣಸು, ಆರ್ಥಿಕವಾಗಿ ಬಹಳಷ್ಟು ಪ್ರಾಮುಖ್ಯತೆ ಹೊಂದಿರುತ್ತದೆ. ಅಲ್ಲದೇ, ಇದರ ಬಗ್ಗೆ ಸಂಶೋಧನೆ ನಡೆಸಲು ಸಂಶೋಧಕರಿಗೆ ಇದು ಒಂದು ಒಳ್ಳೆಯ ವಿಷಯ. ಈ ಮೆಣಸಿನ ಭೌಗೋಳಿಕ ಮೂಲವನ್ನು ಪತ್ತೆ ಮಾಡಲು ಸಂಶೋಧಕರು ತೀವ್ರವಾಗಿ ಅಧ್ಯಯನ ನಡೆಸುತ್ತಿದ್ದಾರೆ.
