Vaccines have led to many of the world's greatest public health triumphs, but many deadly viruses, such as HIV, still elude the best efforts of scientists to develop effective vaccines against them.
Trials are underway for a new vaccine to combat the most deadly form of malaria. For the first time ever, researchers will use a virus found in chimpanzees to boost the efficacy of the vaccine.
An unexpected discovery in marine biomedical laboratories at Scripps Institution of Oceanography at UC San Diego has led to new, key information about the fundamental biological processes inside a marine organism that creates a natural product currently being tested to treat cancer in humans. The finding could lead to new applications of the natural product in treating human diseases.
Damaged or defective genes have long been known to be the cause of some cancers. Over the past decade, however, scientists have discovered that even healthy genes can be switched on or off and can cause cancer without any changes in the underlying DNA sequence--although how this happens has remained poorly understood.
Tumor imaging with positron emission tomography (PET) may improve the diagnosis and subsequent treatment of lung cancer patients, according to a recent review.
