Life
We summarize the week's scientific breakthroughs every Thursday.
- Life
Life began when algorithms took control
Digital storage of molecular information is the key to defining life and understanding its origin, astrobiologists say.
- Microbes
The most personal data on your phone is your microbiome
Phones carry more than your contacts and messages. They’ve got your microbiome too.
- Animals
Tiny frogs host an illusion on their backs
How dyeing dart frogs move changes how predators see the amphibians, a new study finds.
- Neuroscience
The simplest form of learning is really quite complex
Habituation, the ability to ignore irrelevant stimuli, is the simplest form of learning but may require a whole neural network.
- Life
Bacteria’s tail spins make water droplets swirl
When bacteria band together, they can turn a fairly tame drop of water into a swirling vortex.
- Animals
Fish-eating spiders are the stuff of nightmares
Spiders that feast on fish can be found on every continent but Antarctica, a new review finds.
- Animals
Passenger pigeon population had booms and busts
DNA says the birds recovered from hard times — until people came along.
- Life
Autoimmune diseases stopped in mice
Reprogramming immune cells may offer a way to treat autoimmune diseases without harming the body’s ability to fight infections.
- Neuroscience
Sunbathing may boost endorphins in the body and brain
UV light makes mice churn out a molecule that is a cousin of morphine and heroin, a finding that may explain why some people seek out sunshine.
- Environment
Triclosan may spoil wastewater treatment
Common antimicrobial could make microbes more drug resistant and less efficient at breaking down sewage sludge in municipal treatment plants.
- Health & Medicine
Simple blood test detects heart transplant rejection
Heart transplant recipients whose bodies are starting to reject the new organ might carry genetic warning signs.
- Genetics
Gene variant tied to diabetes in Greenlanders
Greenlanders who carry two copies of a newly discovered gene variant have upwards of 10 times the chance of developing type 2 diabetes.
