One day in the future, we’ll look back in wonder at how our physical objects used to be singular, disconnected pieces of matter.

We’ll be in awe of the fact that a car used to be just a piece of metal full of gears and belts that we would drive from one place to another, that a refrigerator was a box that kept our food cold — and a phone was a piece of plastic we used to communicate to one other person at a time.

It’s a cosmic game of hide-and-seek. A team of astronomers say that the next search for advanced extraterrestrial civilisations should look for stars – or even galaxies – that have vanished without a trace, as anything so unexplainable could only be due to life far more intelligent than us.

Beatriz Villarroel at Uppsala University in Sweden says this crazy idea has been gnawing at her since her first year of graduate studies. Now she and two undergraduates have finally taken the plunge. They scoured multiple surveys of the night’s sky by eye in order to see if any of nearly 300,000 light sources disappeared from one survey to the next.

[3:19] Rajesh Rao and Andrea Stocco test the first human brain-to-brain interface, allowing the brain to be controlled over the internet. When Rajesh plays a video game and thinks about firing at a target, the EEG picks up the signal and sends it across the internet, the Transcranial Magnetic Stimulation or TMS stimulates the region of Andrea’s brain that controls hand movement. This causes Andrea’s index finger to fire the cannon and blow up the target. [Source: World Science Festival YouTube link] Comments.

Physicists working with the Large Hadron Collider beauty experiment (LHCb) have discovered what appears to be an entire family of new particles that our current physics models can’t explain.

The existence of these new forms of matter, known as tetraquarks, challenges our current understanding of the role they play inside the protons and neutrons that make up atoms — the fundamental building blocks of everything we know and love in the Universe.

“We looked at every known particle and process to make sure these four structures couldn’t be explained by any pre-existing physics,” one of the team, Thomas Britton from Syracuse University, told Sarah Charley at Symmetry. “It was like baking a six-dimensional cake with 98 ingredients and no recipe — just a picture of a cake.”

One of the biggest challenges in treating brain cancer has been getting drugs to cross the blood-brain barrier and attack tumours where they’re needed.

But scientists say they’ve now developed a truly soluble liquid aspirin that can make its way into the brain, and, in the lab at least, kill cancerous glioblastoma cells without harming healthy brain tissue.

The research hasn’t been published in a peer-reviewed journal as yet, so we need to take it with a big pinch of salt for now. But scientists from the Brain Tumour Research Centre at the University of Portsmouth in the UK just presented it at the Brain Tumours 2016 conference in Poland.
