Remember the scene in the movie Mission: Impossible when Tom Cruise has to sneak into the vault? He had to do all sorts of moves to avoid detection. That's what it's like to sneak a targeted drug into a kidney and keep it from getting eliminated from the body.
Since kidneys are the filtering agents in our body, they are keen to get rid of small particles that they sense do not belong. And if the kidney does not filter out a particle, excreting it through urine, it may be eliminated by the liver, which uses macrophages to search for and get rid of foreign bodies.
Antibiotics - medicines that treat bacterial infections - have saved millions of lives worldwide since their discovery in the early 20th century. When we fill a prescription at the doctor's office or pharmacy today, most of us take for granted that these commonly prescribed medicines are real, and of good quality.
Aug. 21, 2018 -- In the future, your car windshield could become a giant camera sensing objects on the road. Or each window in a home could be turned into a security camera.
University of Utah electrical and computer engineers have discovered a way to create an optics-less camera in which a regular pane of glass or any see-through window can become the lens.
SAN FRANCISCO--August 20, 2018--To fight viral infections, your immune system calls on CD8 T cells to kill the infected cells. The CD8 T cells can also be used in immunotherapy approaches to kill cancer cells, including the CAR T cell therapy currently attracting broad public attention.
BROOKLYN, New York, Monday, August 21, 2018 - The worldwide market for 3D-printed parts is a $5 billion business with a global supply chain involving the internet, email, and the cloud - creating a number of opportunities for counterfeiting and intellectual property theft.
BOSTON, Aug. 19, 2018 -- Many people rely on contact lenses to improve their vision. But these sight-correcting devices don't last forever -- some are intended for a single day's use -- and they are eventually disposed of in various ways. Now, scientists are reporting that throwing these lenses down the drain at the end of their use could be contributing to microplastic pollution in waterways.
CHARLOTTESVILLE, Va. - University of Virginia mechanical engineers and materials scientists, in collaboration with materials scientists at Penn State, the University of Maryland and the National Institute of Standards and Technology, have invented a "switching effect" for thermal conductivity and mechanical properties that can be incorporated into the fabrication of materials including textiles and garments.
Oxygen deprivation associated with preterm birth leaves telltale signs on the brains of newborns in the form of alterations to cerebellar white matter at the cellular and the physiological levels. Now, an experimental model of this chronic hypoxia reveals that those cellular alterations have behavioral consequences.
A Princeton-led study has revealed an emergent electronic behavior on the surface of bismuth crystals that could lead to insights on the growing area of technology known as "valleytronics."
The term refers to energy valleys that form in crystals and that can trap single electrons. These valleys potentially could be used to store information, greatly enhancing what is capable with modern electronic devices.
Researchers have developed a system using artificial intelligence that can edit the facial expressions of actors to accurately match dubbed voices, saving time and reducing costs for the film industry. It can also be used to correct gaze and head pose in video conferencing, and enables new possibilities for video postproduction and visual effects.
