We summarize the week's scientific breakthroughs every Thursday.
- Microbes
Magnets diagnose malaria in minutes
A small magnet-based device provides faster, more-sensitive malaria diagnosis in mice.
- Animals
Archerfish mouth is the secret of precision spit
Trained fish shoot down two hypotheses for their fine spit control but reveal fancy mouth work.
- Genetics
Source of coffee’s kick found in its genetic code
Coffee doubled up on caffeine-making genes. Those genes evolved independently from similar ones found in tea and chocolate plants.
- Paleontology
World’s largest dinosaur discovered
A plant-eating dinosaur named Dreadnoughtus schrani has claimed the record for most massive land animal discovered to date.
- Neuroscience
Children’s brains shaped by music training
After two years of an enrichment program, children’s brains showed more sophisticated response to spoken syllables.
- Animals
A fish reared out of water walks better
The normally aquatic fish Senegal bichir raised on land suggests how ancient species might have transitioned into terrestrial ones.
- Animals
Ducks may like water, but they don’t use it to navigate
Scientists tracking ducks in Illinois with radar found that the waterfowl didn’t bother using a river to navigate their way south.
- Animals
Bats hunt ballooning túngara frogs by echolocation
Bat echolocation tracks the billowing vocal sacs of male túngara frogs.
- Materials Science
Silkworms spin spider-strong threads
Silkworms with a spider protein make silk tough enough to be woven into clothing.
- Health & Medicine
Tiny mites are probably crawling all over your face
Two skin mites, relatives of spiders, might populate the faces of all adult humans, according to a DNA survey.
- Life
ZMapp drug fully protects monkeys against Ebola virus
In a test, 18 monkeys injected with the Ebola virus and treated with an experimental drug called ZMapp survived.
- Neuroscience
Pulses to the brain bring memory gains
The ability to associate faces with words is boosted when an outer part of the brain is stimulated, a study shows.
