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.

Environmental change may spur growth of ‘rock snot’
A controversial new theory suggests alga that forms rock snot isn’t an invader, but a low-key species native to many rivers.

E. coli’s mutation rate linked to cells’ crosstalk
When E. coli cells are in smaller crowds, their genes mutate at an increased rate.

MERS outbreak picks up pace in Middle East
As the number of MERS cases increases, researchers race to learn more about the deadly virus carried by camels.

Some birds adapt to Chernobyl’s radiation
Some birds seem to fare well in and near the Chernobyl exclusion zone, but overall the nuclear disaster has been bad news for the region’s bird populations.

One giant leap for zit-causing microbes
A bacterium that lives on humans and causes acne also hopped to domesticated grapevines and relies on the plant for crucial DNA repairs.
