NORMALLY I WOULDNT EVEN POST SOMETHING LIKE THIS BUT LIKE JUST WATCH THIS SPIDER ROBOT DANCE OK

this is the PINNACLE of human creation

LOOK AT HIM GOOOOOOOOO

THIS IS MEANT TO BE LIKE A CUTE FUNNY VIDEO BUT I HAVE ARACHNOPHOBIA AND IM LITERALLY SHAKING AND SO ANXIOUS WATCHING THIS OMG

newton-artemis-fido-scamander asked: omg a science blog who likes frank turner wowowww

Ahhhh yes chemistry, Frank Turner’s mum, and reading festival are definitely among my turn-ons right now!

Surface Tension.

Curious how this sorcery happens? You bet you are.
An insect like a wasp or a water strider can rest atop the water, held up by surface tension. This means that the cohesive force of the water molecules sticking to each other is stronger than the force of the bug being pushed down by gravity. This works because it spreads its weight out over a large surface area (like snowshoes).
That creates a slight indentation in the top of the water, changing the direction that the light coming down is refracted and re-directing it slightly sideways (that’s where the bright halos around the dark areas come from). And what’s the absence of light? 
A shadow.
All those words in picture form:

The Difference Between an Asteroid, Meteor and a Comet: 

Asteroids (Bo.Right) and comets(Bo.Left) are both classified as ‘near earth objects’. An asteroid is composed of mainly metals and rock whereas comets are mostly ice (hence the long tail), sometimes containing carbon, and come from much further away in the solar system. 

When a comet comes within distance of the sun, dust is liberated from the icy tail: forming meteoroids. Asteroids also break-up into meteoroids but, because they are much larger, will normally have to endure impact with each other before this happens. When meteoroids enter the Earth’s atmosphere and heat up, they become meteors (Perseid Meteor; Top) if they survive this without vaporization and make it to the Earth’s ground, they proceed to become described as meteorites.

Spermatophore: is essentially a glob of spermatozoa along with nutrients the male has stored specially. It is described as a nuptial ’gift’ to help the female produce offspring. For example butterflies need lots of sodium to lay their eggs. Some insects, mollusks and other inveterate (such as arachnids) do this. How polite.

The Human Brain Project:
                            Is the extraordinary innovation to attempt to completely map the human brain and create a super computer with the capabilities of realistically reflecting the mega completion it holds its mystery. Based in Switzerland -along with 80 other European constitutions- they,cooperatively, will combine technology and neuroscience to achieve the feat. It will allow us to see how the brain works; a new way study and (finally) objectively classify brain diseases: giving us an insight otherwise impossible experimentally and theoretically. Not only will it hold new beginnings for medicine but will spark development into computing technology: a ‘neuro-morphic computer’ capable of behaving as a human brain - the capacity to learn from experience. I, for one, am thoroughly excited!

Embryonic Stem Cells:  As you are likely to know, stem cell research is the source of a great controversy because embryos are required. There are other ways of getting stem cells (such as from umbilical cords) however it isn’t efficient enough for proper research. However scientist have found a way to turn adult spinal blood cells into those of a 6 day old embryo. This is done by creating holes in the membrane of the cells with electrodes and injecting 4 types of plasmid. 14 days later the cells have completed their metamorphosis. This is a massive breakthrough; removing the issue from politics and accelerating research. This method is safe (no chance of cell mutations when applied[no cancer]) and efficient (60% success rate). We could soon be curing the incurable.

How Do Bees Fly?
Even though it is often used as a famous example of ‘science doesn’t work’, how bees can lift their own weight plus the weight of pollen and nectar was discovered wayyyy back in 2005. Scientists filmed a bee in flight at 6000 frames a second. 
It turns out the bee will beat it’s wings around 230 times a second at a 90degree arc. This, in comparison to the fruit fly’s 200bps, proved their first discovery that insects that are smaller don’t always beat their wings faster. Next they mimicked the bee by creating a scaled-sized robot wing. Instead of creating a a single lift per beat (like bird or plane physics which mathematicians initially deemed the bees flight impossible with) It sort of ‘bobs’: peaking it’s lift at the begging middle and end of each wing flap. 
It’s flight is much more similar to the hovering of a humming bird. Apart from that, bees generate lift expectantly with high pressure and low pressure similar to the Bernoulli principle.
However, what is interesting is when the bees were put in chambers of oxygen and hydrogen (air density similar to that on high mountains) the bees demonstrated superior control by being able to increase the wing-flaps arc to 140degrees.  Increasing the amplitude without increasing the frequency. (Sort of like a bike changing gears). Essentially switching their flight pattern to that of other insects.-http://www.guardian.co.uk/uk/2005/nov/29/science.research-http://www.livescience.com/528-scientists-finally-figure-bees-fly.html

Why Do Mosquito Bites Itch? 
It is only the female mosquito that will bite, and when she does we have all experienced the irritating itch that lasts the day. What happens is:
1) She pierces the skin with her proboscis and searches for blood vessels in the upper epidermis.
2.) When she does this, she releases saliva into the blood; her spit contains digestive enzymes and anti-coagulant which keeps the blood flowing. The body’s reaction to this is to release histamine, causing the blood vessels in the area to swell.  
3.) This swelling then presses on the nerves which gives us that annoying urge to itch.
