- Prime Minister Narendra Modi flagged off the first ever diesel to electric converted locomotive twin engine of ten thousand Horse Power at DLW Varanasi.
- He also inspected an exhibition on locomotives at DLW campus. Such locomotives will be more economical and will increase the speed of goods trains.
- Laying the foundation stone of Ravidas Janmasthali area development project in Varanasi, the Prime Minister said all should get benefits of government schemes irrespective of caste, creed and other factors.
- Prime Minister Narendra Modi invoked Sant Ravidas on his birth anniversary to urge people to end caste discrimination and identify those who promote it for self-interest.
- PM Modi said caste discrimination is an impediment in achieving social harmony.
- He said Guru Ravidas envisioned an India where there is no discrimination and that everyone is taken care of.

- A scientist who raised early alarms about climate change and popularized the term “global warming” has died. Wallace Smith Broecker was 87.
- The longtime Columbia University professor and researcher died 18th feb. at a New York City hospital, according to a spokesman for the university’s Lamont-Doherty Earth Observatory. Kevin Krajick said Broecker had been ailing in recent months.
- Broecker brought “global warming” into common use with a 1975 article that correctly predicted rising carbon dioxide levels in the atmosphere would lead to pronounced warming.
- He later became the first person to recognize what he called the Ocean Conveyor Belt, a global network of currents affecting everything from air temperature to rain patterns.
- “Wally was unique, brilliant and combative,” said Princeton University professor Michael Oppenheimer. “He wasn’t fooled by the cooling of the 1970s.
- He saw clearly the unprecedented warming now playing out and made his views clear, even when few were willing to listen.”

- A multidisciplinary study has found evidence for humans hunting small mammals in the forests of Sri Lanka at least 45,000 years ago.
- The researchers discovered the remains of small mammals, including primates, with evidence of cut-marks and burning at the oldest archaeological site occupied by humans in Sri Lanka, alongside sophisticated bone and stone tools.
- The hunting of such animals is an example of the uniquely human adaptability that allowed H. sapiens to rapidly colonize a series of extreme environments apparently untouched by its hominin relatives.
- In a new paper published in Nature Communications, an international team of scientists has revealed novel evidence for the unique adaptability of Homo sapiens.
- The study, led by scientists from the Max Planck Institute for the Science of Human History, alongside colleagues from Sri Lankan and other international institutions, shows that human populations were able to specialize in the hunting of small arboreal animals for tens of thousands of years.
- This is the oldest and longest record of sophisticated, active primate hunting by foragers. This work also highlights the distinctive ecological capacities of H. sapiens relative to its hominin ancestors and relatives.
