RE: The elegant nature of science
"For months now, there's been speculation that researchers might have finally created time crystals - strange crystals that have an atomic structure that repeats not just in space, but in time, putting them in perpetual motion without energy.

Now it's official - researchers have just reported in detail how to make and measure these bizarre crystals. And two independent teams of scientists claim they've actually created time crystals in the lab based off this blueprint, confirming the existence of an entirely new form of matter.

The discovery might sound pretty abstract, but it heralds in a whole new era in physics - for decades we've been studying matter that's defined as being 'in equilibrium', such as metals and insulators.

But it's been predicted that there are many more strange types of matter out there in the Universe that aren't in equilibrium that we haven't even begun to look into, including time crystals. And now we know they're real.

The fact that we now have the first example of non-equilibrium matter could lead to breakthroughs in our understanding of the world around us, as well as new technology such as quantum computing.

"This is a new phase of matter, period, but it is also really cool because it is one of the first examples of non-equilibrium matter," said lead researcher Norman Yao from the University of California, Berkeley."

RE: The elegant nature of science
Interesting fact: Despite their great ability to mimic the myriad colors of their surroundings, octopuses are colorblind. However, research has shown that their skin is covered with a layer of photoreceptor cells similar to those in their eyes. One theory is that the chromatophores, the pigment-filled skin cells in which they expand and contract to produce said colors, overlay these monochromatic photoreceptors, acting as gel filters that allow their bodies to, in a sense, see color.

It is unknown whether or not these photoreceptor cells are connected to the central brain (which oddly enough is wrapped around their esophagus). There are a large number of neuron clusters in each arm. These "arm brains" (if you will) can control the appendages independently from the central brain. For instance, arms continue to search for food and pull it back to the animal even after being severed from the body. In his book Other Minds (2016), Peter Godfrey-Smith compares the octopus's command of the arms to blinking and breathing in humans: "These are activities that normally happen involuntarily, but through attention you can assert control over them" (103). Therefore, it's very possible that, depending on the circumstances, chromatic changes can be controlled by both the central and arm brains.

Very cool! I'm going to look at these papers some more.

Step up to the front of the class, New Zealand, and take a bow. You've been promoted. Yes

"Geologists, who look at the rocks (and tend to ignore the humans), group Europe and Asia into its own supercontinent - Eurasia - making for a total of six geologic continents.

But according to a new study of Earth's crust, there's a seventh geologic continent called 'Zealandia', and it has been hiding under our figurative noses for millennia.

The 11 researchers behind the study argue that New Zealand and New Caledonia aren't merely an island chain.

Instead, they're both part of a single, 4.9-million-square kilometre (1.89 million-square-mile) slab of continental crust that's distinct from Australia.

"This is not a sudden discovery but a gradual realisation; as recently as 10 years ago we would not have had the accumulated data or confidence in interpretation to write this paper."

Not when he learns the researchers were 10 Maori and one Ozman. Big Grin

Now, this...

"Scientists believe they are on the verge of obtaining the first ever picture of a black hole.

They have built an Earth-sized "virtual telescope" by linking a large array of radio receivers - from the South Pole, to Hawaii, to the Americas and Europe.

There is optimism that observations to be conducted during 5-14 April could finally deliver the long-sought prize."
