Using data gathered by the NASA/ESA Hubble Space Telescope, astronomers have calculated the mass inflow and outflow rates of cool ionized gas around our Milky Way Galaxy and found an unexpected and so-far unexplained surplus of inflowing gas. Prior to this new study, astronomers knew that the galactic gas reserves are replenished by inflow and [...]
Humans have a threshold limit for instantly processing one to four elements accurately; and it seems that our species is not alone, says a team of scientists from France and Australia. “Guppies, angelfish and even honeybees are capable of distinguishing between quantities of three and four, although the trusty insects come unstuck at finer differences; [...]
Lunar orbiters such as India’s Chandrayaan-1 spacecraft and NASA’s Lunar Reconnaissance Orbiter (LRO) recently detected water icy on the floor of some of the south polar craters, but no one is sure exactly when or how that ice got there. A new study by researchers from Brown University and NASA’s Goddard Space Flight Center suggests [...]
Researchers have developed a method for statistically predicting impacts of climate change on outbreaks of tularemia in humans. New results show that tularemia may become increasingly common in the future in high-latitude regions.
In 2018, vast amounts of snow were spread across most of the Arctic region and did not melt fully until late summer, if at all. Researchers documented the consequences of this extreme weather event at Zackenberg, Northeast Greenland by extensively monitoring all components of the local ecosystem for more than 20 years, allowing them to compare life in the extreme year of 2018 to other, more 'normal,' years.
The interactive map uses wartime data from The National Archives to pinpoint more than 30,000 locations that were struck in the UK over the course of the war -- including the first ever attack on British shores on October 16, 1939.
Researchers have implicated 10 new genes in the development of schizophrenia using a method called whole exome sequencing, the analysis of the portion of DNA that codes for proteins. A global consortium of schizophrenia research teams incorporated genetic data from over 125,000 people to gain deeper insights into the genetic underpinnings of schizophrenia.
By collaborating globally in a new, large-scale effort, researchers have made strong progress in sequencing genomes from regions and countries across Africa. These findings will enable more broadly representative and relevant studies ranging from basic through clinical genetics.
Viruses are non-living creatures, consisting of genetic material encased in a protein coat. Once the virus infects a living organism, it can replicate itself and continue on. But what happens if a virus lacks the proper tools to infect an organism? How can it propagate? Researchers have uncovered a novel virus that may help answer those questions.
The 2019 Global Agricultural Productivity Report, shows agricultural productivity growth -- increasing output of crops and livestock with existing or fewer inputs -- is growing globally at an average annual rate of 1.63%.
Estrogen has a significant role in overall brain health and cognitive function. That's why so many studies focused on the prevention of cognitive decline consider the effect of reduced estrogen levels during the menopause transition. A new study suggests a cognitive benefit from a longer reproductive window complemented with hormone therapy.
Fruit drinks and flavored waters that contained added sugars and/or low-calorie (diet) sweeteners dominated sales of drinks intended for children in 2018, making up 62% of the $2.2 billion in total children's drink sales. The report also found that companies spent $20.7 million to advertise children's drinks with added in sugars in 2018, primarily to kids under age 12.
