Fast test reveals drug-resistant bacteria
A new test uses time-lapse photography to see within a few hours whether individual bacterial cells are vulnerable to antibiotics.
- Genetics
Evolve and Linkage turn science into games
In the two new games Evolve and Linkage, biological principles are made entertaining and strategic.

Year in review: Science faces Ebola epidemic
West Africa’s 2014 Ebola epidemic showed what can happen when a contagious virus emerges where cultural practices, public fears and porous borders fuel the spread of disease.
- Neuroscience
Year in review: Memories vulnerable to manipulation
New experimental results in 2014 helped bring scientists closer to understanding how the brain manipulates memories to make sense of the world.
- Neuroscience
Cocoa antioxidant sweetens cognition in elderly
Very high doses of antioxidants found in cocoa may prevent some types of cognitive decline in older adults. But that’s not an excuse to eat more chocolate.
- Neuroscience
Year in review: Young blood aids old brains
Ingredients in young blood can rejuvenate old mice’s bodies and brains, scientists reported in 2014.
- Genetics
Domestication did horses no genetic favors
Horses bear the cost of domestication in the form of harmful genetic variants, a study of equine DNA finds.
- Animals
The dinosaurs in the backyard
Chickens are some of the closest relatives of dinosaurs, and though genetic tinkering the birds might even one day be turned into tiny dinos.
