A new type of therapy aimed at reversing the gene-silencing that promotes cancer-cell growth has shown promising results in a small clinical trial. Forty-five late-stage lung cancer patients who received a two-drug combination designed to restore anti-cancer gene activity survived about two months longer than the expected four months, and ...

Biomedical engineers have developed a new liquid material that in early experiments in rats and humans shows promise in restoring damaged soft tissue relatively safely and durably. The material, a composite of biological and synthetic molecules, is injected under the skin, then "set" using light to form a more solid ...

Human neural stem cells are capable of helping people regain learning and memory abilities lost due to radiation treatment for brain tumors, a new study suggests.

Stem cell therapy may restore cognition in patients with brain cancer who experience functional learning and memory loss often associated with radiation treatment, according to a laboratory study.

Researchers have analyzed recent federal strategies to restore forests on western U.S. forestlands. They evaluated treatments implemented under the U.S. National Fire Plan (NFP); activities included removing trees, shrubs, grasses and litter with the goal of either protecting communities from wildfires or restoring open forests and low-severity fire.

The use of scientific methods can help understand the materials used in centuries old artwork.

Even long after it is formed, a memory in rats can be enhanced or erased by increasing or decreasing the activity of a brain enzyme. For the first time, a study in behaving animals with functioning brains has found that a single molecule, PKMzeta, is both necessary and sufficient for ...

Scientists have discovered that a specific type of human cell, generated from stem cells and transplanted into spinal cord injured rats, provide tremendous benefit, not only repairing damage to the nervous system but helping the animals regain locomotor function as well. The study focuses on human astrocytes -- the major ...
