We summarize the week's scientific breakthroughs every Thursday.
- Animals
Dino-bird had wings made for flapping, not just gliding
Archaeopteryx fossils suggest the dino-birds were capable of flapping their wings in flight.
- Neuroscience
How biology breaks the ‘cerebral mystique’
The Biological Mind rejects the idea of the brain as the lone organ that makes us who we are. Our body and environment also factor in, Alan Jasanoff says.
- Neuroscience
Depression among new mothers is finally getting some attention
Scientists search new mothers’ minds for clues to postpartum depression.
- Neuroscience
Readers muse about memory, magnetic monopoles and more
Readers had questions about the physical trace of memory, magnetic monopoles, blowflies and more.
- Neuroscience
The debate over how long our brains keep making new nerve cells heats up
Adult humans don’t have newborn nerve cells in a memory-related part of the brain, a controversial paper suggests.
- Animals
This baby bird fossil gives a rare look at ancient avian development
A 127-million-year-old fossil of a baby bird suggests diversity in how a group of extinct birds grew.
- Anthropology
Humans don’t get enough sleep. Just ask other primates.
Short, REM-heavy sleep bouts separate humans from other primates, scientists find. Sleeping on the ground may have a lot to do with it.
- Plants
These petunias launch seeds that spin 1,660 times a second
One species of petunia spreads its seeds explosively, giving them a rotation of 1,660 times per second.
- Ecosystems
When bogs burn, the environment takes a hit
Bogs and other peatlands around the world store outsized amounts of carbon. Climate change and agriculture are putting them at risk.
- Animals
In a pack hunt, it’s every goatfish for itself
Pack hunting among goatfish is really about self-interest.
- Ecosystems
Pollution regulations help Chesapeake Bay seagrass rebound
Regulations that have reduced nitrogen runoff into the Chesapeake Bay are driving the recovery of underwater vegetation.
- Earth
By 2100, damaged corals may let waves twice as tall as today’s reach coasts
Structurally complex coral reefs can defend coasts against waves, even as sea levels rise.
