Scanner data can help New York state farmers boost market sales
Julie and Steve Rockcastle, founders of Green Heron Growers in New York's Cattaraugus County, are always trying to figure out what works and what doesn't when it comes to selling their grass-fed beef at farmers markets. So after a Cornell study showe.....»»
Several groups of birds and mammals avoid wind turbines, finds review
While wind power is an important part of the green transition, its downsides include the disturbances caused by wind turbines in animal habitats. According to the international review of the Natural Resources Institute Finland (Luke), many bird and m.....»»
Characterizing the role of oxidized tryptophan residues in repairing damaged photosystem II protein
Photosynthesis refers to the fundamental biological process of the conversion of light energy into chemical energy by chlorophyll (a green pigment) containing plants. This seemingly routine process in plants sustains all the biological life and activ.....»»
Exoplanets" climate: It takes nothing to switch from habitable to hell, say researchers
The Earth is a wonderful blue and green dot covered with oceans and life, while Venus is a yellowish sterile sphere that is not only inhospitable but also sterile. However, the difference between the two is only a few degrees in temperature. A team o.....»»
The Sahara Desert used to be a green savannah: Research explains why
Algeria's Tassili N'Ajjer plateau is Africa's largest national park. Among its vast sandstone formations is perhaps the world's largest art museum. Over 15,000 etchings and paintings are exhibited there, some as much as 11,000 years old according to.....»»
Breakthrough Listen scans entire galaxies for signals from extremely advanced civilizations
In 1960, Dr. Frank Drake led the first Search for Extraterrestrial Intelligence (SETI) experiment at the National Radio Astronomy Observatory in Green Bank, West Virginia. In the more than sixty years that have since passed, astronomers have conducte.....»»
