This Week: Ancient water = ancient habitat?
In the News: Accidents: Why Do They Happen?
If you teach a group of monkeys that blue corn tastes yucky, they switch to pink corn. What happens when a monkey raised to detest pink corn enters the group? You might be surprised!
Bad feet? Aching back? Impacted wisdom teeth? Blame balky designs inherited from your relatives. How has evolution equipped — or mal-equipped — us for modern life? How do big brains support culture that supports big brains?
And how did it traverse 460 kilometers of ocean? Apparently by crossing a narrow band of ice during the last Ice Age. A new study echoes evolutionary giants Darwin and Wallace and highlights the role of sea level in animal migration.
Study finds that bees “read” the electric field of a flower. First-ever detection of electric-field detection by animal not in water makes evolutionary sense, but how come nobody ever saw this before?
How will rising temperatures affect endangered species? Are there ways to abate the consequences, and are they being tested? Can we even be certain that climate change is the cause of specific declines?
A common mole never sees the light of day, but it can pinpoint the source of food in just a few seconds — thanks to its newfound stereo smelling ability. If two ears help you hear in stereo, what good are two nostrils?
The explosion of data — in meteorology, genetics, spying and physics — requires new storage technology. DNA has been storing data for billions of years. Could life’s “hard disk” help tame today’s data explosion?
Research in salty ponds shows how one species of pupfish becomes three — in a few cases. More important, it shows why this did not happen in thousands of other locations. Does an impenetrable “death valley” isolate viable species?
Dig the dung beetle. Sample the belly button. Tilt your brain — and see what happens. Watch bees cook their enemies. Drive through the cabbie’s brain. Check out pretty pix of pretty chicks. All weird. All here!
Life is biology is species: But how many species live on Earth? About six million arthropods (insects, spiders and crustaceans), says a new study.
Bacteria: you’ve seen one, you’ve seen them all? Not. There’s a chemical war going on in that Petri dish, and a new study identifies specialist “super-killers” can kill off a broad range of competitors. Could “bacterial soldiers” help us fight resistance to antibiotics?
A chemical from plastics “looks” like estrogen to the body. If it makes female fish more likely to flirt with males of a different species, could endocrine disruptors cause cross-breeding, and a decline in native fish after invaders enter their rivers?
An alluring flash pattern is only the first step in firefly reproduction. Females actually pay more attention to the “nuptial gift” that carries sperm. A new look at these popular creatures shows that the battle of the sexes is more subtle and complex than we thought.
As a new conversion of soy protein into a meat-like material reaches the market, we also look into meat grown, cell by cell, in lab dishes. Could in vitro meat be in your future, and would that solve ethical, health and environmental problems?
Plants and animals are in a constant struggle for survival and reproduction. Plant toxins prevent most animals from eating their seeds and destroying them. No kidding: A desert mouse is smart enough to eat edible fruit flesh without triggering the “mustard-oil bomb”!
