After taking a pill, the drugs it contains are distributed throughout the body, reaching the tissues and cells affected by disease and performing their intended function. However, they also enter healthy cells, where…
Amide bonds are chemical linkages essential to biology, medicine and materials chemistry. Peptide bonds, a class of amide bonds, link amino acids to form proteins. Amide bonds are also important in medicines and…
Quantum materials do things ordinary materials cannot. They carry current without any loss, or conduct only along their outer edge while the inside insulates. Future quantum computers and quantum sensors will run on…
Could you imagine if pagers made a comeback? Sure, your smartphone would still be your notepad-flashlight-camera-personal assistant-MP3 player-wallet-social media browser. But imagine if pagers made it so easy to do…
Researchers often use antibodies to detect specific molecules or biological markers because they are remarkably precise at recognizing their targets. However, finding the faint signals of cancer in blood samples is a…
Cities trying to cool sweltering streets often set broad tree canopy targets. But those targets can overlook the reality that not all shade is equally useful, and not every neighborhood has room for more trees.
Modern technologies have made it possible to uncover a growing "hidden proteome"—proteins encoded by parts of the genome that researchers previously overlooked. Advances in sequencing and protein analysis are making it…
What are the chances of finding extraterrestrial life in our solar system? Frank Postberg, a professor of planetary science at Freie Universität Berlin, has published a study in Science Advances with an international…
When plant roots are injured—by insects, for example—the pressure inside the root drops, and a pressure wave spreads rapidly throughout the root system. In neighboring roots, tiny proteins that act as mechanical…
When Pliny the Younger recorded his firsthand experience of the eruption of Mount Vesuvius 2,000 years ago—a cataclysm that buried Pompeii and killed his uncle, Pliny the Elder—he provided enough detail about the date…
Nanyang Technological University, Singapore (NTU Singapore) scientists have developed a way to "supercharge" a plant's natural immune response.
Researchers at The University of Texas at Austin have teamed up with pharmaceutical company Eli Lilly and Company to uncover how storage conditions affect mRNA lipid nanoparticles (LNPs), the technology behind COVID-19…
SKA-Low is a radio telescope under construction in Western Australia. It will operate across a wide frequency range, from 50 to 350 MHz, and will be the most sensitive telescope of its kind ever built. The completed…
Medical researchers, clinicians and pharmaceutical scientists often study small molecules called metabolites, which are produced in living cells through a variety of processes, including the breakdown of food, chemicals…
We are continuously sending information to each other, transmitting zeros and ones through a giant network of connected computers and devices. Scientists are now trying to extend this familiar concept of the internet to…
The U.S. housing bubble of the early 2000s sent home prices soaring before the market crashed in 2007–08, triggering a foreclosure crisis and a deep recession.
A Husker research team's latest research could open the door to broader use of a class of materials whose electrical properties may someday power next-generation electronics, high-density energy storage, improved…
Using the James Webb Space Telescope (JWST), a team of astronomers led by the University of Maryland identified water, methane and ammonia in the atmosphere of HATS-6 b, a giant planet 500 light-years from Earth. The…
Are there any geographical differences in how people experience weather conditions? This question was investigated in the citizen science project Kallt och svettigt (Cold and sweaty) for a year with the help of school…
Covered by Phys.org, The Guardian – Science. The robotic spacecraft that failed to rescue an aging NASA telescope plunged back to Earth on Friday less than three months after launching on the bold mission.
