We summarize the week's scientific breakthroughs every Thursday.
- Animals
Playful pups conceived via in vitro fertilization for the first time
Scientists have solved the mystery of how to perform in vitro fertilization in dogs, which could help rid canines of heritable diseases.
- Genetics
Liberia’s Ebola outbreak largely traced to one source
Ebola’s spread and evolution in Liberia echoes patterns seen in Sierra Leone.
- Neuroscience
Busy eyes can make ears go temporarily deaf
When challenged with a tough visual task, people are less likely to perceive a tone, suggesting that perceptual overload can jump between senses.
- Neuroscience
Eyes hard at work can make ears go temporarily deaf
When challenged with a tough visual task, people are less likely to perceive a tone, suggesting that perceptual overload can jump between senses.
- Animals
Water bears’ genetic borrowing questioned
A new analysis of tardigrade DNA suggests that water bears don’t swap many genes with other organisms after all.
- Animals
For male peacock spiders, the best dancers get the girl
Male peacock spiders dance to attract the ladies. And those that perform the best get the girl, a new study finds.
- Animals
Gut bacteria compounds bring cockroaches together
Gut bacteria in young German cockroaches (Blattella germanica) produce fragrant compounds that, when excreted, attract other roaches.
- Animals
Gut bacteria’s compounds bring cockroaches together
German cockroaches may rely on gut bacteria to help attract fellow roaches.
- Paleontology
New dating of dino ancestor challenges Triassic timeline
New dates for geologic layers of well-known fossil formation show that dinosaurs and their ancient relatives were separated by less time than researchers thought.
- Genetics
DNA editing shows success in mosquito sterilization
A new gene drive that sterilizes females could reduce numbers of malaria mosquitoes
- Health & Medicine
High-potency pot smokers show brain-fiber damage
People who smoke potent pot had signs of damage in a brain communication link.
- Animals
Pygmy slow loris hibernates in winter
The pygmy slow loris truly hibernates, making it the first primate found outside Madagascar to do so, a new study says.
