Take a look at that crumpled-up piece of litter on your desk, compressed by the laws of physics and tossed aside. It remembers what you did, even if no one else does.

The Large Hadron Collider sits underground, spanning over five miles across beneath the bucolic suburbs of Geneva, Switzerland. This metal behemoth serves to try and understand the most basic building blocks of our universe. The question stands, then: if ghosts are real, shouldn't the LHC have found them?
When all sources of errors have been ruled out and 4096 phoney votes have still been given to a candidate, who do you blame? In some cases, these kinds of glitches may be coming from outer space, according to scientists who discussed this cosmic conundrum today at the annual meeting of American Association for the Advancement of the Sciences in Boston. Just to be clear, this does NOT mean that aliens influenced the 2016 US election.
Last year, the pair of LIGO experiments announced a discovery a hundred years in the making: Gravitational waves, tiny ripples in space time from a pair of colliding black holes a billion light years away. You might wonder what scientists will do with two giant gravitational wave detectors now that they have fulfilled their primary goal. Well, those ripples weren't the end of the story — they were the start of a whole new saga in astronomy.
Climate change is bad, and humans are causing it with all of our cars and factories belching greenhouse gases into the atmosphere. Now that that's out of the way, and since it doesn't seem like the US government is planning to do anything about it, what if we could actually use those emissions for good — like to produce electricity?
Video: A swinging pendulum is notoriously mesmerising — that's why hypnotists are always swinging pocket watches in front of someone's eyes to put them under. But when you add an extra point of articulation, creating a double pendulum, the seemingly random and flailing motions that ensue go well beyond hypnotic.
You might wonder why Mars gets all the interplanetary attention when Venus, our sister planet, is actually closer. Well, the hellish orb has the hottest surface in the solar system, hotter even than Mercury. Combined with its dense, caustic atmosphere, none of our computers can handle Venus for more than a few hours. Now, scientists think they have come up with a solution.
Physicists have long known that the Sun spins, like the Earth. But a few decades ago, they realised the surface of the Sun spins more slowly than their models predicted — not by a lot, but enough to signal that something they didn't understand was going on. This kicked off a solar mystery, and some scientists started to doubt their own understanding of the Sun's behaviour.
