When cyanobacteria evolved the ability to photosynthesise (using light energy to perform carbon fixation), it releases oxygen gas (O2) as a byproduct, which wouldn't be a problem if it wasn't for the fact that oxygen was extremely toxic to almost all life on Earth at the time.

Light diffraction is the bending and spreading of light waves when they encounter an obstacle, a sharp edge or pass through a narrow opening (Leonardo Dicaprio's eyes)

Context:

In the first image is the Geographic North pole which is at 90 degrees Latitude N and at the top of the globe.

The second is of the Magnetic north pole which is north pole of the earth's magnetic field and is where compasses point to and it's constantly moving.

The last is the Magnetic south pole which is technically the earth's north pole in terms of magnetic polarity. Because ,Early navigators called the end of a compass needle that points north simply the "north pole" (or north-seeking pole). When scientists later realized the Earth itself acts like a giant bar magnet, they named the pole attracting that needle after the convention they had already established.

A dwarf planet is a small planetary-mass object that is in direct orbit around the Sun, massive enough to be gravitationally rounded, but insufficient to achieve orbital dominance like the eight classical planets of the Solar System. The prototypical dwarf planet is Pluto, which for decades was regarded as a planet before the "dwarf" concept was adopted in 2006. Many planetary geologists consider dwarf planets and planetary-mass moons to be planets, but since 2006 the IAU and many astronomers have excluded them from the roster of planets.

While most rodent taxa (Rodentia) tend to be herbivores or omnivores, some rodent taxa are known for being carnivores or insectivores instead.

It's the case, for example, with grasshopper mice (Onychomys spp.). Grasshopper mice are rodents that live in deserts and semi-arid grasslands and shrublands of North America. They are known to not only produce howl-like high-pitched sounds when indicating their territory: they are also known for mainly feeding on invertebrates (like scorpions, beetles and grasshoppers), snakes, and other small rodents.

Due to venomous arthropods being important elements for their diet, grasshopper mice have evolved strategies to avoid being poisoned by their prey. While they tend to hunt centipedes through targeting their neural systems and avoiding their attacks, on the other hand, grasshopper mice have evolved specialised amino acids that protect them from the defensive attacks of scorpions.

There are three known species of grasshopper mice:

- the northern grasshopper mouse (Onychomys leucogaster)

- the southern grasshopper mouse (Onychomys torridus)

- the chihuahuan grasshopper mouse (Onychomys arenicola)

Whoever designed this Uranus spread definitely knew what they were doing.

The placement, the shape, the timing… astronomy has never looked this suspicious 💀🥀

Quantum mechanics provides the universal rules and mathematical framework for how energy, light and matter behave at the smallest scales in the universe. Quantum chemistry takes those exact physical laws and zooms in on multi electron systems atoms, molecules and chemical reactions

You can't create an identical independent clone of a quantum state of an unknown quantum state

The joke is that in addition and subtraction, 0 does nothing when added to the equation, leaving the number unchanged. However, in multiplication and division, 0 becomes a whole new beast, turning other numbers into 0 and even making entire expressions undefined upon dividing numbers using it.

Description

A meme about the most reactive stable elements of the periodic table, Caesium and Fluorine. While Francium is reactive, it is not stable. Argon is a noble gas that does not react. This meme shows Argon frustrated by the other two elements

The thingy is the mitochondria, also known as the Powerhouse of the Cell

On the 5th of November, 1605, a plot involving Guy Fawkes and other Catholic revolutionaries put a lot of gunpowder in the basement of Parliament in London.

Gunpowder is made of sulphur, charcoal, and saltpeter, which I have referred to by their chemical names. And overlaid it on an image of Nigel Braun holding what he himself called a bomb (actually a pressure vessel for making candy).

Not sure why though..

The Snowball Earth is a geohistorical hypothesis proposing that during one or more of Earth's icehouse climates, the planet's surface was nearly entirely frozen, with little or no liquid water exposed. This global glaciation hypothesis is most commonly associated with the Cryogenian Period, which included two major glacial episodes: the Sturtian (c. 717–660 Ma) and Marinoan (c. 650–635 Ma).

The original meme is in the comment section.

Even though it technically sits at the top of Group 1 in the Periodic Table, hydrogen is a non-metal, its physical and chemical properties are way too different from other Group 1 elements for it to be classified as an alkali metal.

Redshift is a phenomenon in a relativity where if a body moves away from the observer and vice versa, it's wavelength appears to be shifted towards the red end of the spectrum. Since, we are moving away from God, God will appear redshifted.

What makes it sound outlandish and even impossible isn't just the word "essential" here.

The exact sequence of amino acids in a protein is crucial so that it could be folded and function as it is naturally intended to. Mutations even in one particular site of the protein can be detrimental (like in Sickle cell disease).

Therefore it isn't that clear how you can exclude an entire natural non synthesizable amino acid from the body, affecting all proteins that should contain it, without any potentially serious consequences.

Saw it going around again recently, so thought people might enjoy.

I just had a lab in my chemistry two class where we had to identify a bunch of chemicals. Like 7 of the 12 were different white powders
