A new study found that North America has approximately 3 billion fewer birds that there were in 1970. The loss represents a 29% population decline, making it an "overlooked biodiversity crisis" according to the authors. "I couldn't believe that…
Researchers have developed the "Old World Drought Atlas" (OWDA), an atlas that used tree rings to map the climate history of Europe during the Common Era. The OWDA matches historical accounts of severe drought and wetness with a spatial completeness not…
A research team has tested a new technique that could possibly forecast how a volcanic eruption will happen accurately. The method combined physics and statistics to capture the probability of past eruption patterns. The risk of volcanic eruptions is unpredictable…
Astronomers found a supermassive black hole in an active galactic nucleus producing rapid and periodic eruptions of X-rays every nine hours. The nucleus contains about 400 000 times the mass of the Sun and is about 250 million light-years from Earth. According to a…
Researchers from the University of Colorado Boulder revealed that the purple sky seen in the state was due to the eruption that occurred on Raikoke volcano in Russia, located 7 535 km (4 682 miles) away, on June 22, 2019. The team, composed of atmospheric scientists…
NASA believes that the mysterious comet named C/2019 Q4, which exited the astronomical community this week, is from outside the solar system. The object was discovered by Gennady Borisov, a Crimean astronomer at the MARGO observatory, Nauchnij, on August 30, 2019….
Researchers from Brigham Young University, Utah, studied the chemistry of burning shrubs and made a model that can predict how forest fires will burn in the next 20 minutes instead of the next weeks. The university posted a snippet of the study on their YouTube…
The drawn-out nature of volcanic eruptions can cause more fatalities than the seemingly brief explosion itself, according to a study by researchers from the United Kingdom and Trinidad and Tobago published on August 14, 2019. Residents who live within the vicinity…
An international team of geologists, geophysicists, and mathematicians presented in a newly published study how coupled computer models can exactly display the conditions that resulted in the 2018 Palu earthquake and tsunami – one of the deadliest natural disasters…
Banned pesticides in several European countries were found in New Zealand waterways and agricultural streams, according to a study by a team from the University of Otago. The study was led by Associate Professor Christoph Matthaei from the University of Otago's…
