Lessons for the new year
SN Editor in Chief, Eva Emerson, reflects on looking to nature for insights on how to constructively look ahead - even if just a year -drawing from a handful of this issues natural science stories for her 2015 resolutions.
- Neuroscience

Insect-eating bats implicated as Ebola outbreak source
Insect-eating bats, not fruit bats, may have started the Ebola epidemic.
- Ecosystems
Dam demolition lets the Elwha River run free
Removing a dam involves more than impressive explosions. Releasing a river like Washington state's Elwha transforms the landscape and restores important pathways for native fish.

Contamination blamed in STAP stem cell debacle
Stem cells supposedly made in acid baths were really embryonic stem cells, investigation finds.
- Ecosystems
Cities are brimming with wildlife worth studying
Urban ecologists are getting a handle on the varieties of wildlife — including fungi, ants, bats and coyotes — that share sidewalks, parks and alleyways with a city’s human residents.
- Genetics
The art of DNA folding
Cells must compress genetic material into a nucleus that measures only about 5 micrometers across. To accomplish the feat, cells make loops in the DNA.
- Humans
Precursors of human sperm and eggs made from stem cells
Reprogrammed adult human cells can produce germ cells, precursors of sperm and eggs.
- Animals
Bees, up close and personal
A photo archive from the U.S. Geological Survey's Bee Inventory and Monitoring Lab offers detailed photos of bee species.
