Yeah you're right, there's no way we can ever achieve 0K according to the third law of thermodynamics in a finite number of operation all the cryogenics stuff about cooling atoms to really cold temperature has really its own interesting features as well, such as reaching the state of Bose-Einstein Condensate

Also to be more precise, at 0K atoms still be moving about slowly, they'll move with minimum energy called zero point energy, as quantum mechanics forbid atoms with zero kinetic energy due to the uncertainty principle, which is why I said point of lowest energy, not zero energy.

Yes, you're right as well. Atoms won't be completely stationary at absolute zero, as they would still jiggle [due to zero point energy] (however, as the temperature of the atoms would be 0, the speed would also equal to 0- this is what I meant by them not moving).

oviparous animals lay eggs, and then embryonic development of the egg occurs outside of the. This occurs in all birds, some monotremes (mammals that lay eggs), and most fish, amphibians and reptiles.

viviparous animals have embryonic development take place in the mother, which leads to birth of a functioning animal.

Viviparous plants  have seeds which germinate (develop and put out shoots) before the seeds detach.

Oviparous animals have their embryos develop in eggs in the mother until the eggs are ready to hatch - at which point they come out.

parthenogenetic reproduction is asexual and involves the development of and unfertilised egg cell (gametophyte) into an embryo.

Microlecithal eggs are small and have little yolk.

yolk is part of an egg or egg cell (ovum) the the developing embryo feeds on. It appears yellow in chicken eggs.

The albumin, or "egg white", is a product of secretions from a hen's oviduct (passage from ovaries to the outside).

A strawberry isn't a berry, but a banana is!

A bit old but super interesting (the article allows for some nice discussion about philosophy of the mind):
"University of Washington researchers have performed what they believe is the first noninvasive human-to-human brain interface, with one researcher able to send a brain signal via the Internet to control the hand motions of a fellow researcher."

Biology

There was a paper published a few years ago that proposed an addition to the theory of evolution. Basically, they proposed in their paper that evolution doesn't just favour the fittest organisms but also favours more complexity. They backed up their research by comparing these special ring proteins in fungi and mammalian cells. The proteins form a ring that pumps stuff around the cytoplasm (in essence). In animals only two proteins form a ring, whereas in fungi the ring is formed by three separate proteins that come together. The researchers concluded that there is no advantage to the three ringed protein over the two-protein ring (three rings is newer btw) and proposed that it was just the natural propensity for evolution to make things more complex that made the two-protein ring turn into three.

In terms of molecular biology, the three-part ring arose because of neutral mutations and duplications. Won't go into the details of that, because they're outlined well in the article below.

EDIT: found the article. Really, really interesting read imo

I once again come on to too much bio LOL.

Scientists may have figured out why a lot of objects in the Kuiper Belt have such weird orbits - they've discovered a 9th planet, with about 10x Earth's mass, orbiting our sun. The maths says that the orbit and mass of this planet is sufficient to cause the orbit of the objects in the Kuiper Belt that we see!

The mitochondria is the powerhouse of the cell.

[antony01001000]

While not explicitly a science fact, it still blew my mind the first time I saw it. Mitochondria is the plural term for a mitochondrion.

Seems a little dead now....

 It was recently published that there is a 9th planet (currently named as Planet X) in our solar system. The scientists are still trying to get the visual proof to convince everyone. It's quite amazing to know that we will have another planet in our solar system...just so unbelievable.... .

Back in my day, Pluto was our ninth planet. RIP Puto.

this thread is actually really cool!! 
sure its a bunch of uni students talking about... stuff, but this helps young ones like me to love the never ending facts and theories of science!!!!
thanks guys, keep going though! It got good!
