Throughout the COVID-19 pandemic, experts have advocated for mitigation strategies like masking and vaccination to help reduce the spread of the virus. According to a…
Researchers identify the locations of structural changes in photosystems I and II that allow growth in far-red light. A team of researchers led by Penn…
The number of sunspots on our sun typically ebbs and flows in a predictable 11-year cycle, but one unusual 70-year period when sunspots were incredibly…
A challenge in materials design is that in both natural and manmade materials, volume sometimes decreases, or increases, with increasing temperature. While there are mechanical…
Astronomers may have detected a “sonic boom” from a powerful blast known as a kilonova. This event—called GW170817—is a result of a merger of two…
Detection of antibodies in one infected deer also suggests deer may become reinfected with SARS-CoV-2. Some white-tailed deer living in Staten Island, New York, are…
A novel and better approach at detecting non-uniformities in the optical properties of two-dimensional materials could potentially open the door to new uses for these…
Several FDA-approved drugs — including for type 2 diabetes, hepatitis C and HIV — significantly reduce the ability of the Delta variant of SARS-CoV-2 to…
In 2017, Hurricane Harvey stalled after making landfall over coastal Texas, pouring down record rainfall, flooding communities, and becoming one of the wettest and most…
New high-speed cellphone services have raised concerns of interference with aircraft operations, particularly as aircraft are landing at airports. The Federal Aviation Administration has assured…
5G stands for fifth-generation cellular network technology. It’s the technology that enables wireless communication – for example, from your cellular phone to a cell tower,…
NASA’s Curiosity rover landed on Mars on August 6, 2012, and since then has roamed Gale Crater taking samples and sending the results back home…
Observations of a distant stellar flare could contain the first evidence of coronal rain on a cool, small M-dwarf star. High-resolution spectroscopic observations of a…
It is widely understood that antibodies neutralize viruses by latching onto their surfaces and blocking them from infecting host cells. But new research reveals that…
Roar supercomputer provides computational power for data-intense gene expression studies. While most people in the U.S. may think of bumble bees as the standard yellow…
The largest catalog of gravitational wave events ever assembled has been released by an international collaboration that includes Penn State researchers. Gravitational waves are ripples…
Demonstrating that a material thought to be always chemically inert, hexagonal boron nitride (hBN), can be turned chemically active holds potential for a new class…
