Scientists develops artificial womb to save premature babies

Scientists have developed an artificial womb that can be used in future to save the lives of extremely premature human babies. It was successfully used to incubate healthy baby lambs for a week.

The research showed that preterm lambs were successfully maintained in a healthy, infection-free condition with significant growth, for a period of one week using ex-vivo uterine environment (EVE) therapy.

Key Facts

The artificial womb is a high-tech amniotic fluid bath combined with an artificial placenta. To mimic a womb, researchers had created a temperature-controlled bag filled with electrolyte solution as a substitute for amniotic fluid that lambs swallow and take into their lungs. They had attached the umbilical cord of preterm lamb to the device that exchanges carbon dioxide in blood with oxygen. In early-stage animal testing, the lamb appeared to grow normally inside the system.

Significance

The artificial wombs can facilitate development of premature babies in a uterus-like environment. Further development, EVE therapy can prevent the severe morbidity suffered by extremely premature infants. It can potentially offer a medical technology that does not currently exist.

Navika Sagar Parikrama: Indian Navy’s all-woman team to circumnavigate globe

A six-member all-woman team of the Indian Navy will set sail to circumnavigate the globe on the sailing vessel INSV Tarini. This is the first-ever Indian circumnavigation of the globe by an all-woman crew.

The expedition has been aptly titled ‘Navika Sagar Parikrama’ with an aim to promote women empowerment in the country and ocean sailing by the Indian Navy.

Key Facts

The voyage of Navika Sagar Parikrama will begin from Goa in the first week of September 2017 and culminate on their return in March 2018. The entire distance will be covered in five legs, with stop overs at four ports Fremantle (Australia), Lyttelton (New Zealand), Port Stanley (Falklands) and Cape Town (South Africa) for replenishment of ration and repairs as necessary. The project is considered essential towards promoting Ocean Sailing activities in the Indian Navy while depicting Union Government’s thrust for ‘Nari Shakti’ i.e. empowering women. 

INSV Tarini

INSV Tarini is a 55 foot sailing vessel has been built indigenously by M/s Aquarius Shipyard Pvt Ltd, Goa. It was inducted into the Indian Navy in February 2017. INSV Tarini is the sister vessel of INSV Mhadei. Its mast is 25 metres and has been custom-built by M/s Southern Spars, Cape Town (South Africa), for sailing in extreme conditions. It carries a suite of six sails, including a main sail, head sails (Genoa and stay sails), downwind sails and storm sail. It has Raymarine navigation suite and an array of satellite communication systems on board through which contact can be made from anywhere.

Earlier Expeditions

The first Indian solo circumnavigation was undertaken by Captain (Retd) Dilip Donde from August 2009 to May 2010 onboard the Indian built vessel, INSV Mhadei. The first Indian non-stop solo circumnavigation was undertaken by Cdr Abhilash Tomy from November 2012 to March 2013.
