Finding water on the Moon could be easier with a Goddard technology that uses an effect called quantum tunneling to generate a high-powered terahertz laser, filling a gap in existing laser technology. Locating water and other resources is a NASA priority crucial to exploring Earth’s natural satellite and other objects in the solar system and beyond. Previous experiments inferred, then confirmed the existence of small amounts of water across the Moon. However, most technologies do not distinguish among water, free hydrogen ions, and hydroxyl, as the broadband detectors used cannot distinguish between the different volatiles.

It would need a sta...

Fighting resumes along border of Ethiopia 's northern Tigray , residents tell Reuters "I am hearing sound of heavy weapons starting from this morning,"said a farmer in Kobo area."Last week, I saw Amhara special forces nd Fano heading to the front by bus."   The fighting is a major blow to hopes for peace talks between Prime Minister Abiy Ahmed's government and the Tigray People's Liberation Front (TPLF), the party that controls Tigray.Fighting between forces from Ethiopia's rebellious northern region of Tigray and central government forces has erupted around the town of Kobo, residents and both sides said on Wednesday, ending a months-long ceasefire. Both sides have blamed each other for the outbreak of fighting. "At 5am today (the TPLF) has attacked on the Eastern Front; from Bisober, Zobel and Tekulshe direction. By carrying out such measure, it has effectively broken the ceasefire," the government's communications service...

  The United Nations International Children's Emergency Fund (UNICEF) has warned that children in the   Horn of Africa and Sahel regions   "could die in devastating numbers unless urgent support is provided." That's as the number of drought-stricken people in Ethiopia, Kenya and Somalia — without access to adequate supplies of water — rose from 9.5 million to 16.2 million in the space of just five months, according to the relief agency. "When water either isn't available or is unsafe, the risks to children multiply exponentially," UNICEF Executive Director Catherine Russell said.   "Across the Horn of Africa   and the Sahel, millions of children are just one disease away from catastrophe," she added. Twin threat of drought and conflict UNICEF said drought and conflict in Burkina Faso, Chad, Mali, Niger and Nigeria were driving up water insecurity, resulting in 40 million children facing high to extremely high levels of water vulnerability.

Amazing !!!! He was conceived in 1969 and born in 1987.. At the age of two, he drove a bull and farmed it... It's hard to believe.

Statement by President Joseph R. Biden, Jr. on World Humanitarian Day Today, on World Humanitarian Day, we honor the humanitarian workers around the world who need our protection and support more than ever as they carry out their life-saving work. Nineteen years ago, a terrorist bombing claimed the lives of humanitarian aid workers in Baghdad. On this day, we remember them as well as the sacrifice made by the thousands of aid workers who have been killed, injured, or kidnapped since then.   This year, the world faces unprecedented humanitarian need. More than 300 million people need assistance accessing clean water, emergency medicine, shelter, food and nutrition, protection and other services; more than 100 million are forcibly displaced; and hundreds of millions are experiencing hunger. Humanitarian workers are rising to this challenge, undertaking everyday ac...
