Reading a Cuttlefish's Mind — On Its Skin  

Pity the cuttlefish that tries to play poker. Where humans might blush when embarrassed or go white when frightened, cuttlefish wear their thoughts on their skins much more literally. Our own color transformations are caused by nothing more than changes in the blood flowing right under our skin, and it's a poor marker of what our actual thoughts are. Cuttlefish, by contrast, are covered in up to millions of tiny pigment-filled cells called chromatophores. Muscles in the cells stretch to ...

Why Dandelion Seeds Are So Good At Floating  

Dandelion blowing may be about as close to a universal experience as there is. Kids and adults alike delight in huffing the white fluffy seeds from a dried sample of Taraxacum officinale, and watching them fly away. But as with all things in nature, it only happens that way because it works. Dandelion seeds can travel for miles before setting down, making them particularly efficient fliers. And scientists didn't really know why. Other plant seeds, such as maples, use more of a wing-like...

Astronomers May Have Spotted Another Neutron Star Merger  

In 2017, gravitational waves and light were observed coming from the merger of a pair of neutron stars. The discovery proved that gravitational wave sources could also be viewed at visible, X-ray, and even gamma-ray wavelengths, but has remained the only such event observed to date. Now, researchers have identified a "cosmic look-alike" — an event they believe came from the same type of system as the one that produced the gravitational waves. Seeing Double Such a discovery woul...

Earliest Flesh-Ripping Fish Found (With Nibbled Victims)  

Jumping right out of nightmares and into my heart (it's kind of cute, isn't it?), meet Fincutter, the Bavarian Piranha. Less than three inches long, the Late Jurassic fossil is the earliest ray-finned fish with flesh-ripping teeth — and paleontologists say it was preserved alongside some of its prey. Piranhamesodon pinnatomus ("pinnatomus" = fincutter) turned up in the same fabulously fossiliferous Bavarian quarry that has given us specimens of Archaeopteryx and other key Jurassic an...

In novel concepts of magnetic data storage, it is intended to send small magnetic bits back and forth in a chip structure, store them densely packed and read them out later. The magnetic stray field generates problems when trying to generate particularly tiny bits. Now, researchers were able to put an 'invisibility cloak' over the magnetic structures. In this fashion, the magnetic stray field can be reduced in a fashion allowing for small yet mobile bits.
