By injecting man-made, microscopic tubes into tumors and heating them with a quick, 30-second zap of a laser, scientists have discovered a way to effectively kill kidney tumors in nearly 80 percent of mice. Researchers say that the finding suggests a potential future cancer treatment for humans.

New research has determined an immune mechanism responsible for graft failure in a mouse model of in utero blood cell transplantation, a procedure that could be used to treat human congenital blood disorders. As fetal immune cells were triggered to eliminate the transplanted blood cells by immune molecules obtained from the mother’s breast milk, the [...]

Creating a Second Life avatar, or virtual representation of oneself, that is thin and physically fit may encourage individuals to become healthier and more physically fit in their real lives, according to a new study.
Activation of two different kinds of neurons is necessary for appetitive and aversive memory recall in crickets. Researchers blocked octopaminergic (OA-ergic) and dopaminergic (DA-ergic) transmission and found that this resulted in the inability to recall pleasant and unpleasant memories, respectively.

Researchers have learned that some healthy people naturally developed an immune response against a protein that is made in excess levels in many cancers, including breast, lung, and head and neck cancers. The finding suggests that a vaccine against the protein might prevent malignancies in high-risk individuals.

Although lead content in paint has been restricted in the United States since 1978, environmental health researchers say in major countries from three continents there is still widespread failure to acknowledge its danger and companies continue to sell consumer paints that contain dangerous levels of lead.

Compared to patients without prior heart disease, those who previously had blocked arteries were more likely to die in the hospital. Patients with previous heart disease also received three guideline-recommended treatments — cholesterol-lowering drugs, anti-smoking counseling and ACE inhibitors — less frequently than patients who had not had heart disease. Two treatments — aspirin and [...]
