Our science stories this week included everything from Lichens surviving a mass extinction event, to research that shows how we assess robots, ancient DNA solving a Mediterranean mystery and a game controlled by the mind.
Here’s a snapshot of a few stories we particularly enjoyed. Click on the links to read them in full. You can also see all the week’s yarns here.
It’s not just Titan. Astrobiologists still have eyes for Enceladus
Although NASA’s new Dragonfly mission to Titan will be the first return to the Saturn system to follow up on the discoveries of the Cassini mission, astrobiologists are already prepping to return to another of Saturn’s moons, Enceladus.

A game that really exercises the mind
US computer engineers have reported creating a way for two people to help a third person solve a problem using only their minds.
It’s called BrainNet and, the team from the University of Washington says, it is the first demonstration of two things: a brain-to-brain network of more than two people, and a person being able to both receive and send information to others using only their brain.

World could support many more trees, research shows
The world has room for nearly a billion hectares of extra trees, new research shows.
That would be enough to capture two-thirds of the planet’s human-induced carbon emissions – sucking carbon dioxide from the atmosphere to convert into sugars through photosynthesis

Ancient DNA sheds some light on a Mediterranean mystery
Migrants from Southern Europe were the likely source of distinctive architecture and pottery associated with the ancient Philistines, an analysis of ancient genomes reveals.
According to the Hebrew Bible, the Philistines occupied five separate city-states along the coast of modern-day Israel and the Gaza Strip.

Creepy robots are all in your head
Researchers have mapped out the way our brain decides whether a robot is likeable or looks too human – and therefore repulsive.
The more robots look like humans, the more we like them. But only up to a point.
The effect is reversed once the resemblance becomes too close, when robots begin to strike observers as eerie, unsettling and unlikeable.

Lichens thrived while those around them fell
It seems not everything got fried when an asteroid smacked into the Earth 66 million years ago.
New research suggests some types of lichens – organisms made of fungi and algae living together – seized the moment and evolved into new forms to take up plants’ role in the ecosystem.

And here’s our image of the week:
Researchers have simulated the moment in development when the body starts to separate into two distinct halves – here, yellow and green cells.
Researchers at Rockefeller University in the US have used stem cells to create a 3D model of early embryonic tissues, allowing them to simulate developmental processes as they occur in time and space.
