We summarize the week's scientific breakthroughs every Thursday.
- Science & Society
Big data studies come with replication challenges
As science moves into big data research — analyzing billions of bits of DNA or other data from thousands of research subjects — concern grows that much of what is discovered is fool’s gold.

Fast and furious: The real lives of swallows
In the fields of Oregon, scientists learn flight tricks from swallows.

Flying animals can teach drones a thing or two
Scientists have turned to Mother Nature’s most adept aerial acrobats — birds, bees, bats and other animals — to inspire their designs for self-directed drones.
- Neuroscience
Decoding sommeliers’ brains, one squirt of wine at a time
Researchers use a ‘gustometer’ to control wine portions in experiments comparing the brains of sommeliers and novices.

- Animals
Humboldt squid flash and flicker
Scientists capture the color-changing behavior of Humboldt squid in the wild.
- Life
When bacteria-killing viruses take over, it’s bad news for the gut
A rise in some bacteria-killing viruses in the intestines may deplete good bacteria and trigger inflammatory bowel diseases.
- Animals
If pursued by a goshawk, make a sharp turn
Scientists put a tiny camera on a northern goshawk and watched it hunt. The bird used several strategies to catch prey, failing only when its targets made a sharp turn.
- Genetics
Scientists find new way to corral genetically engineered bacteria
Engineering E. coli to depend on human-made molecules may keep genetically modified bacteria from escaping into nature.
- Neuroscience
Brain’s protective barrier gets leakier with age
Aging influences the breakdown of the blood-brain barrier, which may contribute to learning and memory problems later in life.
- Animals
Diving marine mammals take deep prey plunges to heart
In spite of their diving prowess, Weddell seals and bottlenosed dolphins experience irregular heart rates when they venture beyond 200 meters under the sea.
- Health & Medicine
Immune system ‘reset’ may give MS patients a new lease on life
With the help of their own stem cells, MS patients can stop the disease in its tracks in many cases.
