January 24, 2020 – This Copernicus Sentinel-2 image features an area in the Santa Cruz Department of Bolivia, where part of the tropical dry forest has been cleared for agricultural use. Since the 1980s, the area has been rapidly deforested owing to a large agricultural development effort where people from the Andean high plains (the […]

January 23, 2020 – As well as providing global navigation services, Europe’s Galileo satellite constellation is acontributing to saving more than 2000 lives annually by relaying SOS messages to first responders. And from now on the satellites will reply to these messages, assuring people in danger that help is on the way. This ESA-design ‘return […]

January 21, 2020 – Material falling into a black hole casts X-rays out into space – and now, for the first time, ESA’s XMM-Newton X-ray observatory has used the reverberating echoes of this radiation to map the dynamic behaviour and surroundings of a black hole itself. Most black holes are too small on the sky […]

January 15, 2020 -According to independent analyses by NASA and the National Oceanic and Atmospheric Administration (NOAA), Earth’s global surface temperatures in 2019 were the second warmest since modern recordkeeping began in 1880. Globally, 2019 temperatures were second only to those of 2016 and continued the planet’s long-term warming trend: the past five years have […]

Geneva, January 15, 2020 – The year 2019 was the second warmest year on record after 2016, according to the World Meteorological Organization’s consolidated analysis of leading international datasets. Average temperatures for the five-year (2015-2019) and ten-year (2010-2019) periods were the highest on record. Since the 1980s each decade has been warmer than the previous […]

January 8, 2020 – When you see someone being unfair, disloyal or uncaring toward others, do you feel a sense of moral outrage in the form of a twisting stomach, pounding heart or flushing face? And is it possible that your body’s response depends on your political affiliation? Researchers with USC’s Brain and Creativity Institute set out […]

January 7, 2020 – NASA’s Transiting Exoplanet Survey Satellite (TESS) has discovered its first Earth-size planet in its star’s habitable zone, the range of distances where conditions may be just right to allow the presence of liquid water on the surface. Scientists confirmed the find, called TOI 700 d, using NASA’s Spitzer Space Telescope and […]

January 2, 2020 – More than half of Earth’s rivers freeze over every year. These frozen rivers support important transportation networks for communities and industries located at high latitudes. Ice cover also regulates the amount of greenhouse gasses released from rivers into Earth’s atmosphere. A new study from researchers in the University of North Carolina […]

The North Atlantic Current transports warm water from the Gulf of Mexico towards Europe, providing much of north-western Europe with a relatively mild climate. However, scientists suspect that meltwater from Greenland and excessive rainfall could interfere with this ocean current. Simulations by scientists from the University of Groningen and Utrecht University showed that it is […]

December 27, 2019 – When astronomers look around the solar system, they find that planets can be made out of almost anything. Terrestrial planets like Earth, Mars, and Venus have dense iron cores and rocky mantles. The massive outer planets like Jupiter and Saturn are mostly gaseous and liquid. Astronomers can’t peel back their cloud […]

Dec. 19, 2019 – Melatonin sets the internal clock. Researchers from Leibniz-Institute of Freshwater Ecology and Inland Fisheries (IGB) in an international team have analyzed data on the impact of light pollution on melatonin formation in humans and vertebrates. They found that even the low light intensities of urban skyglow can suppress melatonin production. Melatonin […]

AMHERST, Mass. Dec. 18, 2019 – A new analysis of the changing character of runoff, river discharge and other hydrological cycle elements across the North Slope of Alaska reveals significant increases in the proportion of subsurface runoff and cold season discharge, changes the authors say are “consistent with warming and thawing permafrost.” First author and […]
