Researchers ditch approximations, find small-scale structures produce important effects using new computer codes
“This phenomenon can vary sea level by as much as 10 cm along the Colombian and Venezuelan coast," researcher says
Redefinition will remove a nagging uncertainty in the official kilogram’s mass
New research findings will help mitigate effects of extreme space weather
Novel technology could boost the output power of the electron beam and enable long-range communications or remote sensing for a fraction of the current energy costs
Nanorods' behavior first theorized 20 years ago, but not seen until now
The detection of ionized oxygen indicates that many very brilliant stars, several dozen times more massive than the Sun, have formed in the galaxy and are emitting the intense ultraviolet light needed to ionize the oxygen atoms
The LIGO Scientific Collaboration and the Virgo Collaboration identify a second gravitational wave event
Led by Lehigh University professor Joshua Pepper, the team includes nearly 40 members in 10 countries across 4 continents
To lyse cells, purify proteins, or develop nanotechnology, scientists and technologists often turn to ultrasonic liquid processors.
From a distance, these carbon planets would be difficult to tell apart from more Earth-like worlds. Their masses and physical sizes would be similar
The research shows that more oxygen, carbon, and iron atoms exist in the sprawling, gaseous halos outside of galaxies than exist within the galaxies themselves, leaving the galaxies deprived of raw materials needed to build stars and planets.
