We summarize the week's scientific breakthroughs every Thursday.
- Neuroscience
Music doesn’t move some people
One study offers a glimpse into those who find no enjoyment in tunes.
- Animals
Chemical in male goat odor drives the lady goats wild
A new study shows that male goats exude pheromones from their skin that could make female goats ready to roll in the hay.
- Physics
Flying snakes get lift from surrounding air vortices
When a paradise flying snake leaps into and glides through the air, it’s getting lift from small, swirling vortices in the air around it.
- Animals
Peacocks sometimes fake mating hoots
Peacocks may have learned a benefit of deception by sounding their copulation calls even when no peahens are in sight.
- Neuroscience
Brain uses decision-making region to tell blue from green
Language and early visual areas of the brain are not crucial for distinguishing colors, an fMRI study suggests.
- Genetics
Neanderthal Man
The hottest thing in human evolution studies right now is DNA extracted from hominid fossils. Svante Pääbo, the dean of ancient-gene research, explains in Neandertal Man how it all began when he bought a piece of calf liver at a supermarket in 1981.
- Microbes
Power-packed bacterial spores generate electricity
With mighty bursts of rehydration, bacterial spores offer a new source of renewable energy.
- Animals
Algal blooms created ancient whale graveyard
Whales and other marine mammals died at sea and were buried on a tidal flat in what's now in the Atacama Desert in Chile.
- Neuroscience
Girls may require more mutations than boys to develop autism
New results may help explain why more males wind up with autism.
- Life
Rivalry helps fruit flies maintain brainpower
In lab tests, males dim mentally after generations without competitors.
- Animals
The mystery of the missing fish heads
When scientists opened up the stomachs of shortfin mako sharks, they found that nearly all of the digesting fish had no heads or tails.
- Animals
Methylation turns a wannabe bumblebee into a queen
Epigenetic changes to bumblebee DNA turns a worker into a reproductive pseudo-queen, suggesting that genomic imprinting could be responsible for the bumblebee social system.
