Observations of saturated and unsaturated fatty acid behavior could impact public health. Researchers have developed a new microscopy technique that allows for the direct tracking of fatty acids after they’ve been absorbed into living cells. What they found using this technique could have significant impact on both the understanding and treatment of obesity, diabetes and cardiovascular disease.

A new fad diet seems to pop up every few years. Atkins, Zone, Ketogenic, Vegetarian, Vegan, South Beach, Raw – with so many choices and scientific evidence to back each, it’s hard to know what’s healthy and what’s not...

A new vaccine technique can fight a certain type of breast cancer in mice. HER2-positive breast cancer accounts for between 20 and 30% of all cases of breast cancer in humans. Researchers from the University of Copenhagen and the University of Bologna now show that the same type of cancer can be fought in mice with help of their new vaccine.

In cases of breast cancer, the immune system has difficulties distinguishing between cancer cells and healthy cells. Therefore, it normally does not launch a protective immune response that can prevent cancer cells from growing and spreading...

Researchers using CT scans and 3D printing have created accurate, custom-designed prosthetic replacements for damaged parts of the middle ear, according to a study being presented today at the annual meeting of the Radiological Society of North America (RSNA). The technique has the potential to improve a surgical procedure that often fails because of incorrectly sized prosthetic implants, researchers said. Hearing works partly through the transmission of vibrations from the ear drum to the cochlea, the sensory organ of hearing, via 3 tiny bones in the middle ear known as ossicles...

Researchers show in mice that transplanted muscle cells display improved engraftment in a magnetic field How can damaged cardiac tissue following a heart attack best be treated with replacement muscle cells? A team under the supervision of the University of Bonn is now presenting an innovative method on mice: Muscle replacement cells, which are to take over the function of the damaged tissue, are loaded with magnetic nanoparticles...
