When we take a stroll on the beach, we walk on the sand without any trouble. The sand appears solid and is difficult to compress. When we put the same sand grains in an hourglass, they behave very differently: the sand flows ...
Researchers are using new, experimental techniques like Shear Assisted Processing and Extrusion (ShAPE) and friction stir welding to produce metal components that are lighter, stronger, and more precise than ever before. ...
When Emalie Hayes and her colleagues began exploring ways to test wastewater for the COVID-19 virus, little did she know that the simple, inexpensive device she developed would end up being used around the world to identify ...
Electrical signals control a vast number of activities in the human body, from exchanges of messages between brain neurons and stimulation of the heart muscle to the impulses that enable hands and feet to move, among many ...
A key source of information underpinning the upcoming National Climate Assessment suggests that heavy precipitation days historically experienced once in a century by Americans could in the future be experienced on several ...
Carnegie Mellon University physicists in Pittsburgh are one step closer to building new particle detectors for the Compact Muon Solenoid (CMS) experiment at CERN's Large Hadron Collider (LHC).
In the midst of growing white supremacy, the rise of the Black Lives Matter movement and, recently, public discussion about the whiteness of Jews following Whoopi Goldberg's arguably ignorant remarks about the Holocaust, ...
In a new review article in Nature Photonics, scientists from Los Alamos National Laboratory assess the status of research into colloidal quantum dot lasers with a focus on prospective electrically pumped devices, or laser ...
Pink Floyd's Dark Side of the Moon cover, voted the greatest classical rock album of all time, intended to portray the prism and dispersion of light into a rainbow as a certain metaphorical symbolism and a light show that ...
In research that may eventually help crops survive drought, scientists at Princeton University have uncovered a key reason that mixing material called hydrogels with soil has sometimes proven disappointing for farmers.
