Wham! Bullseye! Galactic collision creates a ring of black holes and neutron stars

“So you have a nice, normal spiral galaxy, right, just out there doing its thing, when BAM! A smaller galaxy careens right through the middle of it like a bullet! Chaos, fireworks, explosions everywhere! And then, after the second galaxy leaves, the first one starts changing shape, transforming, into a big ring, and then stars start dying, and now there’s this huge ring a gazillion miles across that’s just littered with black holes and other weird objects sucking down matter and spewing out death rays!”

For the first time, physicists have used antimatter in one of the most famous physics experiments

“The experiment - an antimatter version of the famous double-slit setup - was carried out by researchers from Switzerland and Italy in order to lay the groundwork for a novel line of super-sensitive experiments that might help solve a mystery concerning the Universe's two domains of matter.”

The personalised medicine revolution is finally happening and it'll change the way we think about cancer

“But thanks to genetic advances, doctors are now changing the way they think about cancer, and are looking at your cancer's genes, rather than where it's located, to figure out the best treatment plan.”

Your age might affect how you see this classic optical illusion, study says

“My Wife and My Mother-in-Law is one of the most well-known optical illusions in the world.

“It hinges on facial perception: You can either see a young woman turning away or the profile of an older woman staring solemnly towards the left side of the drawing.”

There's a vicious cycle behind Alzheimer's that could explain why so many treatments have failed

“The discovery of an aggressive feedback loop between the build-up of protein and nerve damage could be the key to explaining why so many trials of promising new treatments for Alzheimer's disease end in failure.”

The researchers may be right; I can see the young woman by using averted vision - a trick I learned in my youth to see dim stars.
