Particle accelerators such as those at the European Organization for Nuclear Research (CERN) in Geneva are typically highly complex large-scale devices. In these ring-shaped facilities, which are often several kilometers ...
It was 1972 and Apollo astronauts Harrison "Jack" Schmitt and Eugene Cernan had just stepped onto the moon's surface to begin collecting rock and soil samples.
For a long time, scientists assumed that Earth's water was delivered by asteroids and comets billions of years ago. This coincided with the Late Heavy Bombardment (ca. 4.1 to 3.8 billion years ago), a period when planets ...
Fluorine is critical for biomedicine. This element can help drug compounds be more potent and last longer in the body, and its radioactive isotope, fluorine-18, powers medical imaging techniques such as positron emission ...
In 1949, famed mathematician and physicist John von Neumann delivered a series of addresses at the University of Illinois, where he introduced the concept of the "universal constructor." The theory was further detailed in ...
Having good neighbors can be very valuable—even in the atomic world. A team of Amsterdam physicists was able to determine an important property of strontium atoms, a highly useful element for modern applications in atomic ...
Is there anything more dramatic than an exploding star? More than just extraordinarily bright, energetic events that can light up the sky for months, these explosions play important roles in the cosmos. Supernovas create ...
In a Physical Review Letters study, the HOLMES collaboration has achieved the most stringent upper bound on the effective electron neutrino mass ever obtained using a calorimetric approach, setting a limit of less than 27 ...
Off the coast of Antarctica, the sea ice retreated toward the southernmost continent and, like a bottle cap taken off a soda bottle, that reduced pressure slowed down a process of critical carbon dioxide capture, dramatically ...
The same technology behind MRI images of injury or disease also powers nuclear magnetic resonance (NMR) spectroscopy, which is used to analyze biological molecules for research on diseases and therapeutics. While NMR spectroscopy ...
