The density of chain grocery stores has increased globally by 23.6 percent over 15 years (from 2009 to 2023). People in countries with the most chain grocery stores per person buy more unhealthy food and are more likely to be obese.
A galaxy called GLIMPSE-16403, is by no means confirmed as a Population III host. But the identification of even a candidate suggests that it's only a matter of time before we finally locate the first stars in the Universe.
To lay the foundations for a lunar navigation system, NASA's Lunar GNSS Receiver Experiment (LuGRE) has successfully received global positioning system (GPS) signals beamed from Earth's orbit.
Researchers say the 3.47-billion-year-old meteorite impact crater could help explain how life on Earth began.
In 1982, the Syrian government besieged the city of Hama, killing tens of thousands of its own citizens in sectarian violence.The grandchildren of women who were pregnant during the siege still bear marks of it in their genomes.
Continent-sized structures of mineral protruding from the lower mantle towards Earth's outer core may be contributing to an instability of our planet's magnetic field.
Radio astronomers see what the naked eye can't. As we study the sky with telescopes that record radio signals rather than light, we end up seeing a lot of circles.
Part of the system that pumps water, heat and nutrients around the globe is at risk. Climate change could slow the Antarctic Circumpolar Current down 20% by 2050.
Life's most vital elixir may have formed within 200 million years of the Big Bang, new research suggests.
In the new work, Hirose and colleagues at other institutions in Japan and Taiwan propose that the iron core of the Earth formed bonds with helium, allowing the core to act as a reservoir.
These robots can flow around obstacles before hardening into weight-bearing tools that push, throw, twist objects like a wrench—and bear up to 150 pounds of weight.
Astronauts often experience immune dysfunction, skin rashes, and other inflammatory conditions while traveling in space. These issues could be due to the excessively sterile nature of spacecraft.
Ultrahigh Energy Cosmic Rays are the highest-energy particles in the universe, whose energies are more than a million times what can be achieved by humans.
This melting has implications for global climate indicators, including sea level rise, ocean warming and viability of marine ecosystems.
Located 2.5 million light-years away, the majestic Andromeda galaxy appears to the naked eye as a faint, spindle-shaped object roughly the angular size of the full Moon.
