We summarize the week's scientific breakthroughs every Thursday.
- Anthropology
Readers question hominid family tree
Readers sent feedback on hominid origins, fast cameras, slimy sea creatures and more.
- Health & Medicine
Most football players who donated their brains to science had traumatic injury
A self-selected sample of 202 deceased football players, the largest to date, finds that the majority suffered from chronic traumatic encephalopathy.
- Neuroscience
There’s a long way to go in understanding the brain
Neuroscientists offer multiple “perspectives” on how to plug gaps in current knowledge of the brain’s inner workings.
- Animals
Fire ants build towers with three simple rules
Fire ants use the same set of simple rules to produce static rafts and perpetually moving towers.
- Genetics
Resistance to CRISPR gene drives may arise easily
New tools for pest and disease control could become useless without improvements.
- Health & Medicine
Cows produce powerful HIV antibodies
For the first time in any animal, researchers elicit broadly neutralizing antibodies against HIV. Cows’ antibodies could help with drug development.
- Animals
Elephant seals recognize rivals by the tempo of their calls
The distinct sputtering-lawnmower sound of a male elephant seal’s call has a tempo that broadcasts his identity to competitors.
- Tech
This robot grows like a plant
A new soft robot navigates its environment by growing in a manner inspired by plants.
- Genetics
These genes may be why dogs are so friendly
Dog domestication may be the result of just a few genetic changes, including ones that made canines more interested in interacting with people.
- Health & Medicine
Common drugs help reverse signs of fetal alcohol syndrome in rats
A thyroid hormone and a blood sugar drug affect levels of a hormone needed for brain development, study in rats shows.
- Genetics
Dog domestication happened just once, ancient DNA study suggests
DNA of ancient canines counters idea that dogs were domesticated twice, in Europe and Asia.
- Agriculture
GM moth trial gets a green light from USDA
GM diamondback moths will take wing in a New York field trial.
