The U.S. space agency, NASA, reported Monday it has confirmed water can be found in sunlit areas of the moon, indicating water may be far more widespread than previously thought. NASA said it confirmed the discovery using its Stratospheric Observatory for Infrared Astronomy (SOFIA), a flying laboratory onboard a specially modified 747 aircraft. It was previously believed that water molecules could only be found in cold, shadowy areas of the lunar surface.  The results of the study are also published in the latest issue of Nature Astronomy. Drier than the SaharaNASA says SOFIA detected water molecules in Clavius – one of the largest craters visible from Earth – in the moon’s southern hemisphere. The data indicates the presence of water in concentrations of 100 to 412 parts per million – roughly equivalent to a 12-ounce bottle of water – trapped in a cubic meter of soil spread across the lunar surface.  NASA says by comparison, the Sahara Desert has 100 times the amount of water that SOFIA detected in the lunar soil. But regardless how tiny the amount, the discovery raises new questions about how water is created and how it persists on the harsh, airless lunar surface. NASA scientists say the recent finding is encouraging for the agency’s plans to establish a sustainable human presence on the moon by the end of the decade. It remains to be determined if the water SOFIA found is easily accessible for use as a resource.  When people first landed on the moon in 1969, it was believed to be completely dry. But observations from Earth and spacecraft since then have revealed evidence of ice and hydration in a variety of regions. But before now, scientists were not able to distinguish in what form the water was present. Future SOFIA flights will look for water in additional sunlit locations and during different lunar phases to learn more about how the water is produced, stored and moved across the moon. The data will add to the work of future moon missions to create the first water resource maps of the moon for future human space exploration.

The World Health Organization Monday once again warned nations against “the politicization” of the COVID-19 pandemic, saying it has led to confusion and disrespect for science, and made the pandemic worse.At the agency’s regular briefing, WHO Director-General Tedros Adhanom Ghebreyesus said last week saw the highest number of COVID-19 cases reported since the pandemic began. Many northern hemisphere nations are also seeing a rise in hospitalizations, with intensive care units filling up in Europe and North America.Tedros said in recent days, several leaders around the world critically evaluated their situations and took action, such as implementing lockdowns, working and studying from home and other restrictions to try to limit the spread of the virus.He said the WHO understands how these restrictions lead to “pandemic fatigue,” and the very real mental and physical toll they take on people. But he said governments and citizens cannot give up, noting there are no “magic solutions” to the outbreak just hard work from leaders and society at all levels.“Science continues to tell us the truth about this virus. How to contain it, suppress it and stop it from returning, and how to save lives among those it reaches,” said the WHO chief.Tedros said countries that have followed the science have suppressed the virus and minimized deaths.But, he said, “where there has been political division at the national level; where there has been blatant disrespect for science and health professionals, confusion has spread, and cases and deaths have mounted.”The director-general said, “what will save lives is science, solutions and solidarity.”

The World Meteorological Organization is calling for urgent action to mitigate the impact of climate change in Africa, which threatens food security, health and socio-economic development on the continent. WMO has just launched a multi-agency publication, FILE – An aerial shot shows widespread destruction caused by Cyclone Kenneth when it struck Ibo island north of Pemba city in Mozambique, May, 1, 2019.The Food and Agriculture Organization reports the number of undernourished people in drought-prone sub-Saharan African countries has increased by 45.6 percent since 2012. WMO director of Regional Strategic Office, Filipe Lucio tells VOA many more people are likely to go hungry as a result of climate variability and change.”With increased warming, we expect a reduction in terms of food production. We also expect impacts in terms of disease and pests,” Lucio said. “But importantly, we will have impacts generated by flooding on the infrastructure system for agriculture production, which is the main source of livelihoods and food security in the continent.”The report notes new diseases are emerging in regions where they had not been seen before because of rising temperatures and changes in rainfall patterns. For example, malaria epidemics have occurred in the higher altitudes of East African highlands where mosquitoes previously were unable to survive.The economic impact on the continent is also great. WMO Climate Coordinator Omar Baddour says the Gross Domestic Product in five African sub-regions is expected to decrease by 2.25 percent to 12.12 percent as a result of global temperature increase.”It leads to a jobless situation, have less economic activity, less employment and emigration, and so conflicts,” Baddour said. “So, it is really an alarming indicator that we can see as an impact on the African continent.”WMO urges African governments to increase their climate risk management strategies. These involve improving preparedness, prevention and early warning systems based on good data and weather forecasting.It says Africa should employ techniques such as efficient and clean energy sources. It says solar-powered, efficient micro-irrigation, for example improves agricultural yields by up to 300 percent and reduces water usage by up to 90 percent. This, while offsetting carbon emissions.WMO says these techniques have been shown to increase farm-level incomes by five to ten times where they have been employed.

After more than three months under stifling restrictions imposed in response to a second wave of COVID-19 cases, life in Australia’s second-largest city is slowly about to return to normal. Victoria state Premier Daniel Andrews announced Monday that Melbourne’s five million citizens will be able to leave their homes effective Tuesday at midnight, and that all  cafes, restaurants, bars, shops and hotels will be allowed to reopen.   The announcement comes as Melbourne and the surrounding Victoria state recorded its first 24-hour period without any new coronavirus infections since June 9.  The state had been plagued by a dramatic spike of new COVID-19 cases, peaking in August when daily new cases rose above 700.  The resurgence of new cases has been blamed on security lapses at hotels where travelers were being quarantined after traveling overseas.   With zero new cases, Premier Andrews told reporters that “we are able to say that now is the time to open up. Now is the time to congratulate every single Victorian for staying the course.” Andrews also said that travel restrictions limiting people to no further than 25 kilometers from their home will end on November 8, which will allow people in Melbourne to travel to Victoria’s rural areas.   Testing in Kashgar, ChinaHealth authorities in China’s northwestern Xinjiang province have launched a widespread testing effort in Kashgar after 137 new asymptomatic COVID-19 infections were discovered. The new cases were detected after a 17-year-old girl was found to be asymptomatic.  The other asymptomatic cases have been traced to a factory where the girl’s parents work.  Authorities say nearly 3 million people in Kashgar have been tested since the outbreak was detected. Xinjiang was placed under a brief but tight lockdown period after a cluster of coronavirus cases was detected in August.   On the vaccine frontMeanwhile, British-Swedish pharmaceutical giant AstraZeneca announced Monday that a vaccine it has developed in cooperation with the University of Oxford has produced a similar immune response in both younger and older adults, with adverse responses lower among the elderly.   The announcement by the British-Swedish pharmaceutical giant comes the same day The Financial Times newspaper said early reports from testing showed the experimental vaccine, dubbed AZD1222, produces a robust immune response in elderly people, who are among the highest risk from the disease.
