Northern white rhinos are extinct in the wild and there are just two females in captivity in Kenya. Conservationists are working on an artificial breeding programme, using eggs from the females and sperm from a deceased male. Now five embryos have been created. Thomas Hildebrandt of the Leibniz Institute for Zoo and Wildlife Research in Berlin explained the research. President Biden’s first executive order was what’s being called the hundred-day mask mandate. The day before the inauguration a massive analysis of mask-wearing and COVID rates demonstrated a clear, if small, benefit. Epidemiologist Ben Rader told Roland Pease that it got over 300,000 opinions by using the online questionnaire, SurveyMonkey.After the alarming series of record-breaking heatwaves last year, global warming is causing specific problems in the innumerable lakes around the world. Lakes are ecologically particularly vulnerable to extremes. The European Space Agency’s Yestyn Woolway has been analysing past trends, and modelling the future.2020 delivered a record year in hurricanes, which caused around $60 billion dollars in damage to the US alone, according to one estimate. A new technology called Airborne Phased-Array Radar promises to improve the measurements that are currently made by planes that fly right into the eye of the hurricanes, and make the missions safe. It’s being developed at the National Centre for Atmospheric Research and Roland discussed the new technology with the Director of NCAR, Vanda Grubišić.(Image; Najin and Fatu, the only two remaining female northern white rhinos graze in their paddock.
