LTK:
Electric eels seen leaping out of water to attack land predators

I still have a hard time believing that electric eels are real and didn't come straight out of Pokémon.

LTK:
A theoretical physicist from the University of Amsterdam published a paper that presents evidence that dark matter may in fact not exist, and that the discrepancy in gravitational force can be explained by an additional force called dark gravity. I actually haven't got a clue how, the abstract alone is almost completely indistiguishable from sci-fi technobabble. I'll paste it so you can share in the experience of having something fly so far over your head that it classifies as an astronomical event. It all sounds really cool though!


--- Quote ---Recent theoretical progress indicates that spacetime and gravity emerge
together from the entanglement structure of an underlying microscopic theory.
These ideas are best understood in Anti-de Sitter space, where they rely on the
area law for entanglement entropy. The extension to de Sitter space requires
taking into account the entropy and temperature associated with the cosmological
horizon. Using insights from string theory, black hole physics and quantum
information theory we argue that the positive dark energy leads to a thermal
volume law contribution to the entropy that overtakes the area law precisely at
the cosmological horizon. Due to the competition between area and volume law
entanglement the microscopic de Sitter states do not thermalise at sub-Hubble
scales: they exhibit memory effects in the form of an entropy displacement caused
by matter. The emergent laws of gravity contain an additional ‘dark’ gravitational
force describing the ‘elastic’ response due to the entropy displacement. We
derive an estimate of the strength of this extra force in terms of the baryonic
mass, Newton’s constant and the Hubble acceleration scale a0 = cH0, and provide
evidence for the fact that this additional ‘dark gravity force’ explains the
observed phenomena in galaxies and clusters currently attributed to dark matter.

Here's the paper.

Randall Munroe has this to say about that topic:

Case:
"When scientists saw the mouse heads glowing, they knew the discovery was big"


--- Quote ---Kari Alitalo had studied lymphatic vessels for more than two decades. So he knew that this network, which carries immune cells throughout the body and removes waste and toxins, didn’t extend into the brain: This had been accepted wisdom for more than 300 years. “Nobody questioned that it stopped at the brain,” says Alitalo, a scientist at the University of Helsinki in Finland.

Turns out the brain has two lymphatic networks ...  :-o


--- Quote ---This was surprising, to say the least: In the 21st century, major findings involving basic human anatomy are rare. “These days, you don’t make discoveries like this,” Alitalo says. “But every once in a while in science, you stumble on something really unexpected. You open a new door, to a whole new world.”

And it may help a lot of people:

--- Quote ---The discovery is much more than a historical footnote. It has major implications for a wide variety of brain diseases, including Alzheimer’s, multiple sclerosis, stroke and traumatic brain injury.
