Scientists at ETH Zurich and the South African company Strait Access Technologies are using 3-D printing to produce custom-made artificial heart valves from silicone. This could help meet an aging population's growing demand for replacement heart valves.
The human heart has four...
Scientists at Washington University School of Medicine in St. Louis have developed a new imaging agent that could let doctors identify not only multiple types of tumors but the surrounding normal cells that the cancer takes over and uses...
A large-scale genomic analysis has revealed some of the inner workings of the body clock, shedding new light on how it links to mental health and disease.
The study, published in Nature Communications, suggests that being genetically programmed to rise...
Fever is known to help power up our immune cells, and scientists in Shanghai have new evidence explaining how. They found in mice that fever alters surface proteins on immune cells like lymphocytes to make them better able to...
CRISPR-based genetic screens have helped scientists identify genes that are key players in sickle-cell anemia, cancer immunotherapy, lung cancer metastasis, and many other diseases. However, these genetic screens are limited in scope: They can only edit or target DNA....
Instead of searching for a needle in a haystack, what if you were able to sweep the entire haystack to one side, leaving only the needle behind? That's the strategy researchers in the University of Georgia College of Engineering...
Cancer cases have been rising over the years and according to the statistics, the number of people living with cancer will continue to increase. Despite decades of research, cancer treatments are still inefficient and have unacceptable side effects that...
Regular use of a common type of medication, such as aspirin and ibuprofen, significantly improves survival for a third or more patients with head and neck cancer, a new study led by UC San Francisco has found.
Non-steroidal anti-inflammatory drugs,...
Researchers at Duke University have engineered a bandage that captures and holds a pro-healing molecule at the site of a bone break to accelerate and improve the natural healing process.
In a proof-of-principle study with mice, the bandage helped to...
Yale researchers have identified a drinkable cocktail of designer molecules that interferes with a crucial first step of Alzheimer's and even restores memories in mice, they report Jan. 2 in the journal Cell Reports.
The binding of amyloid beta peptides...
Boston University researchers have developed a new, "intelligent" metamaterial—which costs less than ten bucks to build—that could revolutionize magnetic resonance imaging (MRI), making the entire MRI process faster, safer, and more accessible to patients around the world. The technology,...
