If you stand at practically any point on Earth, there is water moving through the ground beneath your feet. Groundwater provides about half of the world's population with drinking water and nearly half of all water used to irrigate crops. It sustains rivers, lakes and wetlands during droughts.
Africa is home to about 410,000 savannah elephants (Loxodonta africana), most of them living in southern Africa. Over 290,000 elephants (70%) are spread across 103 protected areas which vary in size, connectivity and protection.
The first space-based observatory designed to detect gravitational waves has passed a major review and will proceed to the construction of flight hardware. On Jan. 25, ESA (European Space Agency), announced the formal adoption of LISA, the Laser Interferometer Space Antenna, to its mission lineup, with launch slated for the mid-2030s. ESA leads the mission, with NASA serving as a collaborative partner.
Nearly five years ago, a globe-spanning team of astronomers gave the world its first-ever glimpse of a black hole. Now the team has validated both their original findings and our understanding of black holes with a new image of the supermassive black hole M87*. This supermassive black hole, 6.5 billion times the mass of our sun, resides at the center of the Messier 87 (M87) galaxy in the Virgo galaxy cluster, located 55 million light-years from Earth.
Since methane was first detected in Mars' atmosphere 20 years ago, scientists have struggled to uncover its origins and how it is transported around the Red Planet. Measurements from atmospheric samples collected by NASA's Curiosity rover at Gale crater reveal fluctuations in methane levels over days and seasons, but pinpointing the timing and reasons for the variability has proved difficult. These emissions, possibly produced by subsurface microbes, could provide vital evidence of life on Mars. However... Читать дальше...
In a new study published in Science today, JILA and NIST (National Institute of Standards and Technology) Fellow Jun Ye and his research team have taken a significant step in understanding the intricate and collective light-atom interactions within atomic clocks, the most precise clocks in the universe.
Forest fires have destroyed more than 17,000 hectares in Colombia since November, authorities said Friday, as the country faces its hottest January in decades.
A new study from the University of Central Florida's Rosen College of Hospitality Management has found that the loss to tourism-related businesses due to the 2018 Florida red tide bloom is estimated at approximately $2.7 billion.
The United States House of Representatives held more than 700 votes in 2023, but fewer than 30 bills were signed into law. Partisan politics may explain why, with polarization potentially causing enough friction to slow down the legislative process and make the passage of fewer, farther-reaching public laws likelier, according to researchers.
Recording the activity of large populations of single neurons in the brain over long periods of time is crucial to further our understanding of neural circuits, to enable novel medical device-based therapies and, in the future, for brain–computer interfaces requiring high-resolution electrophysiological information.
A recently discovered solar system with six confirmed exoplanets and a possible seventh is boosting astronomers' knowledge of planet formation and evolution. Relying on a globe-spanning arsenal of observatories and instruments, a team led by researchers at the University of California, Irvine has compiled the most precise measurements yet of the exoplanets' masses, orbital properties and atmospheric characteristics.
