Antibody drug conjugates (ADC) are generating excitement with a breast cancer treatment called DS-8201, which has few side effects.
An ongoing measles outbreak is raising new concerns for parents this summer. Camps are trying to do what they can to keep kids safe. Dr. Jon LaPook explains.
Type O blood is the universal donor, but these scientists have found a way to make Type A into Type O. This could double the blood supply for transfusions.
With a lens-free makeover scanning near-field optical microscopes (SNOMs) could become a common lab tool.
We report that 3D-A-DNA structure behaves as a fractal antenna, which can interact with the electromagnetic fields over a wide range of frequencies. Using the lattice details of human DNA, we have modeled radiation of DNA as a helical antenna. The DNA structure resonates with the electromagnetic waves at 34 GHz, with a positive gain of 1.7 dBi. We have also analyzed the role of three different lattice symmetries of DNA and the possibility of soliton-based energy transmission along the structure.
Fruits are major sources of essential nutrients and serve as staple foods in some areas of the world. The increasing human population and changes in climate experienced worldwide make it urgent to the production of fruit crops with high yield and enhanced adaptation to the environment, for which conventional breeding is unlikely to meet the demand. Fortunately, clustered regularly interspaced short palindromic repeat (CRISPR) technology paves the way toward a new horizon for fruit crop improvement and consequently revolutionizes plant breeding. In this review, the mechanism and optimization of the CRISPR system and its application to fruit crops, including resistance to biotic and abiotic stresses, fruit quality improvement, and domestication are highlighted. Controversies and future perspectives are discussed as well.
Cancer cells can spread to other parts of the body through the blood. And now, researchers have developed a new kind of laser that can find and zap those tumor cells from the outside of the skin.
Though it may still be a ways away from becoming a commercial diagnostic tool, the laser is up to 1,000 times more sensitive than current methods used to detect tumor cells in blood, the researchers reported June 12 in the journal Science Translational Medicine.
To test for cancer spread, doctors typically take blood samples, but often the tests fail to find tumor cells even if they are present in a single sample, especially if the patient has an early form of cancer, said senior author Vladimir Zharov, director of the nanomedicine center at the University of Arkansas for Medical Sciences.
