Signs of sleep debt found in the blood
When rats and people skimp on sleep, fats and acids involved in metabolism dwindle.
- Animals
‘The Cultural Lives of Whales and Dolphins’ offers window into cetacean societies
Dolphins and whales pass cultural knowledge to one another, the authors of a new book argue.
- Animals
Rainforest frogs flourish with artificial homes
A rainforest frog population grew by about 50 percent when scientists built pools for tadpoles that mimic puddles made by other animals.
- Neuroscience
Shots of brain cells restore learning, memory in rats
Scientists healed damage caused to rats’ brains from radiation by injecting cells that replenish the insulation on neurons.
- Genetics
Pregnancy in mammals evolved with help from roving DNA
DNA that “jumped” around the genome helped early mammals shift from laying eggs to giving birth to live young.
- Paleontology
Snakes crawled among Jurassic dinosaurs, new timeline says
Earliest snake fossils provide evidence snakes evolved their flexible skulls before their long, limbless bodies.
- Genetics
Scientists find new way to corral genetically engineered bacteria
Engineering E. coli to depend on human-made molecules may keep genetically modified bacteria from escaping into nature.
- Animals
Mountain migration is a roller coaster for bar-headed geese
Bar-headed geese rise and fall to match terrain below them when migrating over the Himalayas.
- Animals
Squids edit genetic directions extensively
In squids, RNA editing means that DNA often does not get the final say in which proteins are created.
- Animals
‘Bag of chips effect’ helps bats find a meal
Bats get a clue to where dinner is by listening to peers attacking prey.
- Animals
Bowhead whales may unlock the secrets to a long, healthy life
Analyzing the genome of the bowhead whale may help scientists understand how the animals live for more than 200 years.
- Ecosystems
Cities are brimming with wildlife worth studying
Urban ecologists are getting a handle on the varieties of wildlife — including fungi, ants, bats and coyotes — that share sidewalks, parks and alleyways with a city’s human residents.
