Share  Starting this academic year,Ben-Gurion University of the Negev (BGU), Israel is now offering a new two-year Master’s program in Environmental Physics and Solar Energy. The program is led by the Albert Katz International School for Desert Studies(AKIS)located on the SdeBoker Campus of BGU. The program is designed for students to gain a deep and diverse understanding and capability in fields related to the environment and natural resources, while also developing their mental flexibility,enabling them to employ methods, terms, and concepts from different areas of research and move betw...

Study Finds 6⁰C Cooling on Land during the Last Ice Age, With Implications about Future Global Warming Ancient groundwater flows from a well in the North China plain during a field campaign in 2004 to measure noble gases to reconstruct past temperature.

(May 12, 2021) -- Low-to-mid latitude land surfaces at low elevation cooled on average by 5.8 ± 0.6 degrees C during the Last Glacial Maximum (LGM), based on an analysis of noble gases dissolved in groundwater, according to a new study published in Nature. Temperature estimates in the study are substantially lower than indicated by some notable marine...

Disposable facemasks can be reused after being heat-treated, a study by University of Tartu researchers shows. Researchers at the Institute of Physics have conducted experiments with medical face masks made by five manufacturers, trying to destroy the virus using three methods: machine washing at 60 degrees, keeping the mask in boiling water for five minutes and keeping the mask in hot water for five minutes. Each method was applied 10 times, and the masks were allowed to dry for 24 hours between each heat treatment. After 10 times, the masks' filtration efficiency and breathability were meas...

Estonian researchers prove disposable medical face masks can be reused after heat treatment By 51shares Disposable face masks are a major cause of the large environmental footprint in the novel coronavirus crisis; a study by the Estonian University of Tartu researchers showed that these masks can, in fact, be repeatedly heat-treated before their efficiency starts to significantly decrease. For the study, the researchers at the University of Tartu Institute of Physics conducted experiments with medical face masks of five manufacturers, trying to destroy the virus using three methods: machi...
