Researchers have demonstrated that a special surface, free of biological contaminants, allows adult-derived stem cells to thrive and transform into multiple cell types. Their success brings stem cell therapies another step closer.

Human embryonic stem cells can now be used to grow bone tissue grafts for use in research and potential therapeutic application. The study is the first example of using bone cell progenitors derived from human embryonic stem cells to grow compact bone tissue in quantities large enough to repair centimeter-sized ...

Biomedical engineers have demonstrated the first all-polymeric bone scaffold that is fully biodegradable and offers significant mechanical support during repair. The technique uses silk fibers to reinforce a silk matrix. Adding microfibers to the scaffolds enhances bone formation and mechanical properties. It could improve repair after accident or disease.

Scientists have proposed that the bony structures in the skin of many early four-legged creatures might have been there to relieve acid buildup in bodily fluids. Analysis of their anatomy suggests that as they ventured out of water, the animals would have had trouble getting rid of enough CO2 to ...

Humans that populated the banks of the river Manzanares during the Middle Palaeolithic fed themselves on pachyderm meat and bone marrow. This is what a new study shows and has found percussion and cut marks on elephant remains in the site of Preresa.

The application of high levels of oxygen to a severed bone facilitates bone regrowth, a new study demonstrates. The results that may one day hold promise for injured soldiers, diabetics and other accident victims.

At first-unnoticed lettering in an ancient Jerusalem tomb identifies first-century artifacts as Christian, researchers say.

Thirty-two previously unidentified genetic regions associated with osteoporosis and fracture have now been identified. Variations in the DNA sequences in these regions confer either risk or protection from the bone-weakening disease.

A clinical trial evaluated the use of stem cells from the pelvic bone marrow to improve heart function. Patients’ own stem cells may preserve heart muscle function after a heart attack.

Researchers have presented evidence that early growth predicts the size, mineralization, shape and strength of the hip bone in childhood.

Physicians have found that stem cells derived from heart failure patients’ own bone marrow and injected into their hearts improved the function of the left ventricle, the heart’s pumping chamber. Researchers also found that certain types of the stem cells were associated with the largest improvement and warrant further study.

Two of the telescopes were found in the 18th-century equivalent of toilets.
