Gene activity change can produce cancer
Scientists have long thought that epigenetic changes, which alter gene activity, can cause cancer. Now they have demonstrated it in a mouse experiment.

Carbs and gut microbes fuel colon cancer
Western nations experience high levels of colon cancer, and carbo-loading gut microbes might explain why, says a new study in mice.

Wine corks may owe quality to gene activity
Discovery of genes that distinguish superior stoppers from inferior ones could help reverse recent global downturn in quality.

A mutated bacterial enzyme gobbles up cocaine
Cocaine is highly addictive, and those attempting to quit often relapse. Modifications to an enzyme that breaks down cocaine could help prevent abstinence setbacks.

Alzheimer’s disease may come in distinct forms
Mouse experiments, if confirmed in people, imply that Alzheimer’s disease treatment should be personalized.

Tibetans live high life thanks to extinct human relatives
DNA shared by modern-day Tibetans and extinct Denisovans suggests people picked up helpful genes through interbreeding with other hominids.

HIV hides in growth-promoting genes
The discovery that HIV can trigger infected cells to divide means scientists may need to rethink strategies for treating the virus that causes AIDS.

Genetic mutation quenches quantum quirk in algae
Studying algae that can and cannot use quantum coherence to harvest light could lead to better organic solar cells and quantum-based electronic devices.

Chimp and human lineages may have split twice as long ago as thought
New estimates of chimpanzee mutation rates suggest humans and chimps last shared a common ancestor 13 million years ago.

Ulcer microbe changes quickly to avoid immune attack
During the initial weeks of infection, Helicobacter pylori, the bacterium that causes stomach ulcers, mutates at a high rate, apparently to evade the body’s defenses.

Designer T cells emerge as weapons against disease
Decades of attempts to boost the immune system’s ability to fight disease are finally starting to pay off. Reprogrammed T cells serve as new weapons against cancer and autoimmune diseases.

Cancer research scores big at Intel ISEF
An innovative statistical analysis of cancer-promoting genes earned a 15-year-old the top prize — and $75,000 — at the Intel International Science and Engineering Fair 2014.
