Genetic diseases are the leading cause of death for infants in the United States. Many doctors treating these infants rely on whole-genome sequencing to target the exact cause of the illness, and hopefully treat the disease in time. However, even the fastest sequencing technique till now has taken about 50 hours to complete, and many severely ill infants simply can't wait that long.
Scientists know a lot about HIV—how it's transmitted, the virus' life cycle, and where it likes to hang out in the body. But they haven't had a good understanding of how it moves between cells in the body, and they have never been able to actually watch it spread. Now a team of researchers from Yale University led a study that recorded the virus infecting the lymph nodes in a mouse to better understand how it infects the body, with the intention of being able to stop that spread in the future. Their work was published today in Science.
Have you ever wondered how whales stay underwater for up to two hours without coming up for air? It's because they use a highly stable protein called myoglobin, which stores oxygen for a long time, to power their muscles. Now researchers from Rice University are working with the protein in order to make synthetic blood for humans, according to a study published last week in the Journal of Biological Chemistry.
With too few donor hearts to satisfy the 123,000 patients awaiting a heart transplant, engineers have been working to design an artificial heart. The artificial hearts approved by the FDA are rigid devices attached to external pumps to mimic how the heart pushes blood through the body. Now researchers from Cornell University have designed an artificial heart made of foam that can pump a higher volume of fluid than any other artificial heart, according to a study published recently in the journal Advanced Materials.
