Linking stress and senility
A gene that's active in the brain may help explain why emotional stress seems to increase a person's likelihood of getting Alzheimer's disease.

Life Swap: Switching genomes converts bacteria
Transplanting the entire genome of one species of bacteria into another paves the way for making synthetic microbes with manmade DNA.
-
Health & Medicine
Nerves are key to longevity effect
The life-extending effect that some animals get from calorie-restricted diets may depend on signals from the brain.
-
Tech
A computer in every cell
Artificial genes inserted into cells make RNA molecules that can perform logical computations.
-
Crossing the Line: Technique could treat brain diseases
With the help of a molecule from the rabies virus, scientists have for the first time selectively ferried a drug across the blood-brain barrier to treat a neurological disease in mice.
-
Health & Medicine
Fluorine highlights early tumors
Microscopic, fluorine-packed particles can make small, cancerous growths easier to detect.
-
New player in cancer risk
RNA snippets of a newly discovered type could be involved in the mechanisms of cancer.
-
Breast Cancer Lead: Overactive gene is linked to disease
A mutated gene that's overly active in breast cancer cells could offer a new target for cancer drugs.
-
Health & Medicine
Visualizing Cancer: Images of tumors can detect gene expression
Subtle features in X-ray images of tumors let radiologists infer which genes are active in the cancerous growth.
-
Health & Medicine
Stem cells not required
Insulin-producing cells in the pancreas proliferate by cell division, unlike other body tissues, which regenerate from adult stem cells.
-
Unintended consequences of cancer therapies
Radiation and chemotherapy can destroy a tumor, but they may also indirectly promote metastasis, the spread of cancerous cells to other organs.
-
Another Layer of Complexity: Short lengths of RNA could provide new form of genetic control
Researchers have discovered a new way that so-called junk DNA could help regulate gene activity.
