We summarize the week's scientific breakthroughs every Thursday.
- Genetics
Can DNA predict a face?
DNA-based facial sketches are moving into the crime-solving arena. With current science, predictions of some features are better than others.
- Animals
Inside the roaring sex lives of howler monkeys
Listening to the intense roars of howler monkeys in Mexico inspired scientists to decipher how and why calls differ among species.
- Archaeology
Search for fossils from the comfort of home
The citizen science website FossilFinder.org lets anyone with an Internet connection look for fossils and characterize rocks at Kenya’s Lake Turkana Basin
- Animals
Mystery deepens for what made tarantulas blue
Blue hair on tarantulas shows what evolution does with iridescence that females probably don’t care about.
- Animals
Snakes evolved from burrowing ancestor, new data suggest
A new X-ray analysis of inner ears is the latest to weigh in on whether modern snakes descended from a burrowing or a swimming reptile.
- Animals
For a python, every meal is like Thanksgiving
Burmese pythons rarely eat, but when they do, they gorge. Unlike humans, pythons have adaptations that allow them to survive on huge meals.
- Genetics
Water bears are genetic mash-ups
Drying out may help tardigrades soak up new DNA, which in turn aids the water bears in withstanding stress.
- Life
DNA doubled in conifer ancestors
The genomes of conifers — pine, cypress and yew trees — doubled twice in the distant past.
- Neuroscience
Taste is all in your head
By targeting certain nerve cells in a mouse’s brain, scientists made plain water turn bitter or sweet.
- Microbes
Gut microbes signal when dinner is done
Helpful E. coli bacteria that live in the guts of animals produce proteins that can decrease an animal’s appetite only 20 minutes after receiving nutrients
- Plants
Conifer ancestors had a double dose of DNA
The genomes of conifers — pine, cypress and yew trees — doubled twice in the distant past.
- Genetics
Mosquitoes engineered to zap ability to carry malaria
Researchers have created a gene drive that prevents mosquitoes from carrying malaria.
