A Purdue University scientist and entrepreneur is working to use simple LED light to help determine if certain chemotherapy options will work for specific patients.
Mayo Clinic researchers, along with national and global collaborators, have developed a potential test for Machado-Joseph disease, or spinocerebellar ataxia type 3 (SCA3) ? a disease that has no cure. They also have clarified the role of a gene target associated with the disease.
New radio images from ALMA show for the first time the direct effect of volcanic activity on the atmosphere of Jupiter's moon Io.
Scientists at Rice's Center for Theoretical Biological Physics detail the structure of dumbbell-like sequences in DNA during interphase that suggest several unseen aspects of chromosome configuration and function.
People have different susceptibilities to SARS-CoV-2, the virus behind the COVID-19 pandemic, and develop varying degrees of fever, fatigue, and breathing problems -- common symptoms of the illness. What might explain this variation? Scientists at the University of California, Riverside, and University of Southern California may have an answer to this mystery.
Certain species of snake -- think pit vipers, boa constrictors and pythons, among others -- are able to find and capture prey with uncanny accuracy, even in total darkness. Now scientists have discovered how these creatures are able to convert the heat from organisms that are warmer than their ambient surroundings into electrical signals, allowing them to 'see' in the dark.
Three decades after Cornell astronomer Carl Sagan suggested that Voyager 1 snap Earth's picture from billions of miles away - resulting in the iconic Pale Blue Dot photograph - two astronomers now offer another unique cosmic perspective: Some exoplanets - planets from beyond our own solar system - have a direct line of sight to observe Earth's biological qualities from far, far away.
Computer modeling of the COVID-19 virus on supercomputers showed that the spike protein visits an intermediate state before it can dock to the receptor protein on the host cell membrane. This intermediate state can be useful for drug targeting to prevent the spike protein to initiate viral infection. The initial findings, which showed the existence of an intermediate semi-open state of the spike protein, was published in the Journal of Chemical Physics.
Some people love spicy food -- the hotter, the better. Others go out of their way to avoid the palate-singeing burn of capsaicin, the compound that gives chili peppers their kick. Now, researchers have developed a portable device (whimsically shaped like a chili pepper) that can reveal how much capsaicin a pepper contains, before biting into it. They report their results in ACS Applied Nano Materials.
Chameleons can famously change their colors to camouflage themselves, communicate and regulate their temperature. Scientists have tried to replicate these color-changing properties for stealth technologies, anti-counterfeiting measures and electronic displays, but the materials have limitations. Now, researchers have developed a flexible film that changes color in response to stretching, pressure or humidity. They report their results in ACS Applied Materials & Interfaces.
