Periodontitis – an advanced form of gum disease that breaks down tissue and bones housing the teeth – affects more than 70 percent of adults aged 65 and older. Engineers have devised various ways to combat the issue, ...
If any part of the body would seem ill equipped to shrink, it would probably be the head and skull. And, yet, researchers reporting in Current Biology on October 23 have found that the skulls of red-toothed shrews do shrink ...
Certain species of catfish are covered with bony plates bristling with thin teeth, similar to extinct vertebrate lineages. These teeth, which regularly fall out and grow back, are used for defense and, in males, to attract ...
Mechanical loading, or forces that stimulate cellular growth for development, is required for creating cartilage that is then turned to bone; however, little is known about cartilage development in the absence of gravity ...
Space travel can cause a lot of stress on the human body as the change in gravity, radiation and other factors creates a hostile environment. While much is known about how different parts of the body react in space, how lungs ...
Researchers from the University of Zurich and the University Hospital Zurich have discovered the protein that enables natural embryonic stem cells to form all body cells. In the case of embryonic stem cells maintained in ...
Models of human disease are beneficial for medical research, but have limitations in predicting the way a drug will behave within the human body using data from non-human models because of inherent differences between species. ...
There hasn't been a gold standard for how orthopaedic spine surgeons promote new bone growth in patients, but now Northwestern University scientists have designed a bioactive nanomaterial that is so good at stimulating bone ...
Researchers at Baylor College of Medicine have played a leading role in sequencing the whole genome of the common white-tailed deer, which has recently been made public by the National Center for Biotechnology Information.
Many things go wrong in cells during the development of cancer. At the heart of the chaos are often genetic switches that control the production of new cells. In a particularly aggressive form of leukemia, called acute myeloid ...
