We summarize the week's scientific breakthroughs every Thursday.
- Animals
Betty the crow may not have invented her hook-bending tool trick
Textbook example of Betty the crow’s proposed insight into toolmaking is now called into question by observations of similar hook bending by wild New Caledonian birds.
- Neuroscience
Aging-related protein may play role in depression
Mouse study reveals link between aging protein and depression.
- Animals
These lizards bleed green
Blood and bones turn naturally green in island lizards. Their evolutionary history still needs explaining.
- Genetics
Ancient reptiles saw red before turning red
The discovery that birds and turtles share a gene tied to both color vision and red coloration is more evidence that dinosaurs probably saw the color red — and perhaps were even red, too.
- Neuroscience
‘Neural dust’ can listen to body’s electrical signals
Tiny crystals can detect electrical signals in nerves and muscles of rats.
- Science & Society
Sea life stars in museum’s glass menagerie
See Leopold and Rudolf Blaschkas’ delicate glass jellyfish, anemones, sea worms and other marine invertebrates at the Corning Museum of Glass.
- Science & Society
FDA OKs first GM mosquito trial in U.S. but hurdles remain
The FDA has concluded that test releases of Oxitec GM mosquitoes on a Florida key poses no significant problem for the environment, but local officials still have to agree
- Paleontology
New fossil suggests echolocation evolved early in whales
A 27-million-year-old whale fossil sheds light on echolocation’s beginnings.
- Genetics
Rats offer clues to biology of alcoholism
Heavy-drinking rats are giving scientists new genetic clues to alcoholism.
- Plants
Internal clock helps young sunflowers follow the sun
A circadian clock helps sunflowers follow the sun’s daily path across the sky
- Neuroscience
Red blood cells sense low oxygen in the brain
Red blood cells sense low oxygen and speed to the scene, a new study suggests.
- Animals
Smart mice have better odds of survival
African striped mice (Rhabdomys pumilio) may survive summer droughts by their wits, a study suggests.
