Barely a week later, cosmologist Lawrence Krauss at Arizona State University tweeted a rumour that the detector had already picked up a signal.

Now Krauss claims that the original rumour has been confirmed by an independent source.

“Stay tuned!” he tweeted. “Gravitational waves may have been discovered!! Exciting.”

The primary reason hoverboards have become public enemy #1 in recent times is due to their unfortunate tendency to catch fire and explode due to their lithium-ion batteries overheating.

But a new lithium-ion battery developed by scientists in the US could put an end to such dramas. Researchers at Stanford University have made the world’s first lithium-ion battery that shuts off before it overheats, then restarts immediately when its temperature has cooled.

Conventional lithium-ion batteries comprise a pair of electrodes and a liquid or gel electrolyte that carries charged particles between them. However, if the battery’s temperature reaches around 150 degrees Celsius (300 degrees Fahrenheit) as a result of a defect or overcharging, the electrolyte can catch fire and trigger an explosion, as we’ve seen in many sad cases.

CRISPR, CRISPR, CRISPR. We’ve all heard about it’s gene editing capability, but it has potential to do so much more — controlling genes and offering a precise delivery system.

More than an editing platform

The CRISPR-Cas9 system does a wonderful job, partly because it targets genes so specifically. It’s not the only system that does this, but it’s the cheapest and easiest to create so far. For those with imagination however, this targeting quality means it could do so much more than simply snip away at sequences. Targeting promoter sequences, delivering a payload to a specific region of DNA…the platform has enormous potential.
