Scientist of the day : Dr. Janet Elizabeth Lane-Claypon

Dr. Janet Elizabeth Lane-Claypon was an English physician who was as one of the founders of epidemiology and was also a pioneer in the use of cohort as well as case-control studies. Educated primarily at home until she entered University College at the age of twenty-two, she went on to earn both PhD and MD within a short span of time. This made her an early example of the ‘Doctor-doctor’ phenomenon. Later, she began her career in research, working first on the bacteriology and biochemistry of milk and subsequently on the effect of the ‘Poor Law’ on the children. By working with two cohorts of babies, she established that breast-fed babies gained weight faster than babies fed with cow’s milk. Moreover, the work enabled her to refute the general belief that heating destroys the nutritious value of milk. Subsequently, she began to advocate reforms in child care, midwifery training and parental services. Later, she moved to the field of epidemiologic research, dealing mainly with the cancer of the breast and developed the ‘case-control study.’ She also researched on cancers of uterus, lip, tongue and skin. In addition to that, she had thirty-two publications to her name

World Wetlands Day

World Wetlands Day is annually held on February 2 to celebrate how wetlands, which are lands saturated by water, help maintain biodiversity on Earth.

Governments, community groups, and individuals around the world celebrate World Wetlands Day with special campaigns to promote the important value that the wetlands play in our lives. The day is promoted via social media, radio and TV broadcasts, and newspapers.

About World Wetlands Day

Wetlands are found near the sea or inland and can be seasonal – they are water logged only during parts of the year, or perennial. They play a crucial role in the ecosystem by:

• Preventing flooding by absorbing water.
• Ensuring that the soil provides a unique breeding ground for vegetation that feeds fish.
• Giving shelter to animals.
• Purifying water by removing sediment.

World Wetlands Day has been observed since February 2, 1997. The day commemorates the anniversary of the signing of the Ramsar Convention in the Iranian city of Ramsar in 1971. The convention is a treaty on the preservation and sustainable use of wetlands.
