Hangover Mastery of the Day: Become a partying champion with this handy hangover how-to from AsapSCIENCE. There’s a lot of dubious drinking advice out there, so it’s good to have the straight-up, scientific dope all in one place.
This was a great addition to their mini-series on hydration and alcohol. watch all of them, it’s currently at three videos but I’m sure Mitch and Greg would love and be so encouraged by having a larger audience.
‘Brinicle’ Ice Finger of Death - BBC
As sea water freezes to form surface ice, the remaining brine sinks, being much denser and colder than the surrounding water. As it descends, the surrounding water freezes upon contact, creating a ‘brinicle’, a frozen sheath of ice that grows downward towards the sea floor. When it touches the sea floor, it kills anything it touches, encasing them in a tomb of ice.
If you ever visit Melanasia and Australia one cannot help but be amazed by the striking blond hair of some of its inhabitants, since these Pacific islands are populated by some of the darkest skinned people in the world. The Aboriginal people of Australia and the South Pacific islands, such as the Solomon Islands,Vanuatu, and Fiji at birth are born with blond hair. In maturity the hair usually turns a darker brown color, but sometimes remains blond. Now, a study of people from the Solomon Islands shows that they evolved the striking blonde trait independently of people in Europe. These Aborigines are the oldest continuous population outside of Africa. The modern Aborigines are the direct descendants of the first explorers to leave Africa and arrive in the South Pacific 50,000 to 70,000 years ago. Scientist believe this genetic mutation appeared in Europe only about 11,000 years ago during the last ice age. THE ORIGINAL BLONDS…….
I saw this with a comment trail of ignorance so i decided to reblog the OP because this is just cool. I knew of none of this, I wonder what evolutionary benefit there is for people in this part of the world to have such light hair when compared to most other people with skin that dark. This honestly is fascinating.
Toronto becomes first city to mandate green roofs
Toronto is the first city in North America with a bylaw that requires roofs to be green. And we’re not talking about paint. A green roof, also known as a living roof, uses various hardy plants to create a barrier between the sun’s rays and the tiles or shingles of the roof. The plants love the sun, and the building (and its inhabitants) enjoy more comfortable indoor temperatures as a result.
Toronto’s new legislation will require all residential, commercial and institutional buildings over 2,000 square meters to have between 20 and 60 percent living roofs. Although it’s been in place since early 2010, the bylaw will apply to new industrial development as of April 30, 2012. While this is the first city-wide mandate involving green roofs, Toronto’s decision follow’s in the footsteps of other cities, like Chicago and New York.
Under the direction of Mayor Richard Daley the city of Chicago put a 38,800 square foot green roof on a 12 story skyscraper in 2000. Twelve years later, that building now saves $5000 annually on utility bills, and Chicago boasts 7 million square feet of green roof space. New York has followed suit, and since planting a green roof on the Con Edison Learning Centre in Queens, the buildings managers have seen a 34 percent reduction of heat loss in winter, and reduced summer heat gain by 84 percent.
But lower utility bills aren’t the only benefit of planting a living roof. In addition to cooling down the city, green roofs create cleaner air, cleaner water, and provide a peaceful oasis for people, birds and insects in an otherwise polluted, concrete and asphalt-covered environment.
A Little Biology For You
Ovaries do not have as much to do with the female ejaculatory process as tumblr would have you believe. Seriously, if your ovaries are exploding, go the fucking hospital, get off tumblr and go to the hospital that shit should not be happening.
The moisture from sexual arousal comes from the Bartholin’s glands just inside the opening of the vagina. Ejaculation comes from the Skene’s gland and the urethra. The ovaries are where the eggs hang out, if anything is going to explode from rapid arousal at least use a gland, sing the praises of your prostate (the skene’s is like a female prostate kind of in conjunction with the G-spot).
But seriously, ovaries should not explode. If men started posted about their balls exploding I’d be equally worried (but I have heard that limp ejaculations can happen but that’s different, it’s not a fucking explosion).
If ovaries are going to respond to the sexual act it’s when the body recognizes there is semen in the vaginal canal and/or the cervix and it’s close enough to menstruation that it’s pretty much like ‘let’s hop on this pregnancy’ but that’s after things are done.
Come the fuck on, it’s really not cute and the phrase is kind of annoying to see, I generally don’t edit reblogs but when I’m checking my tracked tags and i see anything about ovaries responding to much other than that fucking hormonal shift that makes life hell then I’m like ‘really, what the flipping fuck is wrong with you!?’. I kind of want to punch whoever started that shit.
30,000 year old flower revived.
Scientists have resurrected a flower from plant tissues found frozen in Siberian permafrost, thought to be 30,000-32,000 years old. The new Silene stenophylla is healthy and fertile, and producing viable seeds.
The experiment has excited many because it proves that material trapped in the permafrost is recoverable and usable - scientists have been working to recover other species of plant and animal life from the same area, such as the woolly mammoth.

Flatfish found in aquarium after lying undiscovered for 15 years
The bottom-dwelling sand sole - dubbed Nemo - was only discovered when its 40,000-litre open native rockpool tank was routinely cleaned at the Blue Planet Aquarium in Cheshire.
But despite being quite a large fish, staff think the fish may have been a stowaway when the tank was delivered in 1996 as they had no records of the flatfish having arrived at the aquarium .
Acting curator Colin Grist said: ‘We’ve called him Nemo, because we’ve found him, just like in the film - except we didn’t know we were looking.
‘Although we haven’t been aware of its existence it seems to have been doing extremely well.
‘It’s in perfect condition and has obviously been feeding well and probably waiting until the lights go out to go hunting.
He added: ‘It’s extraordinary that it’s managed to have remained hidden for so long but it does go to show just how well evolved it is to its natural environment.’
oh my god
Tetrachromatic vision. Most mammals have poor color vision because they have only two kinds of cones, the retinal cells that discriminate different colors of light. Humans, like other primates, have three kinds, the legacy of a past where good color vision for finding ripe, brightly colored fruit was a survival advantage.
The gene for one kind of cone, which responds most strongly to blue, is found on chromosome 7. The two other kinds, which are sensitive to red and green, are both on the X chromosome. Since men have only one X, a mutation which disables either the red or the green gene will produce red-green colorblindness, while women have a backup copy. This explains why this is almost exclusively a male condition.
But here’s a question: What happens if a mutation to the red or the green gene, rather than disabling it, shifts the range of colors to which it responds? (The red and green genes arose in just this way, from duplication and divergence of a single ancestral cone gene.)
To a man, this would make no real difference. He’d still have three color receptors, just a different set than the rest of us. But if this happened to one of a woman’s cone genes, she’d have the blue, the red and the green on one X chromosome, and a mutated fourth one on the other… which means she’d have four different color receptors. She would be, like birds and turtles, a natural “tetrachromat”, theoretically capable of discriminating shades of color the rest of us can’t tell apart. (Does this mean she’d see brand-new colors the rest of us could never experience? That’s an open question.)
New species of plant buries its own seeds
A botanist has discovered a new species of plant in eastern Brazil whose branches bend down upon bearing fruit and deposit seeds on the ground, often burying them in a covering of soft soil or moss. This trick is an example ofgeocarpy, a rare adaptation to survival in harsh or short-lived environments with small favorable patches. The adaptation ensures seedlings germinate near their parents, helping them stay within the choice spots or microclimates in which they thrive. One well-known practitioner of geocarpy is the peanut, which also buries its fruit in the soil. […]
The team dubbed it Spigelia genuflexa, named after the act of genuflection, or kneeling to the ground.
anyone who thinks plants aren’t cool
look at this
actually if you do think they’re cool, still look at it because god it’s so cool
I love plants!
also can I just
what a fantastic name
I like how they call it a new plant. I like it has never existed before it was discovered. Or it just suddenly evolved into this bending plant thing.
Really it was newly discovered.
I don’t think they’re intending for people to assume it’s literally a new plant
that use of the word “new” is pretty common and easily understood
like “i’m going to try a new food today”
or “i think i’m going to need a new roommate”
All of my love! The joy I had from reading about this is easily compared to the joy of finishing drawing something, buying new comics or getting things in the mail. All of my love and joy! Botany is the shit!
Teeth of the Wolf-Fish
The wolf-fish is also known as the seawolf. A cold-water dweller that can survive all the way up to the top of Greenland thanks to a unique blood antifreeze it produces, the wolf-fish is currently facing conservation crises due to both over-fishing and being caught as by-catch when other fish and crustaceans are harvested.
It’s not even like this fish is up near the top of the ocean or a threat to humans…they chill in the deep benthic zone, on the hard floor of the Atlantic ocean. Thing is, that’s also where wild clams & crabs live - and the wolf-fish loves it some crab. Bottom trawlers often catch them along with their intended targets, and this leads to a massive number of inadvertent deaths. The fact that people love to catch these ugly dudes for mounting, especially in their shallower habitats near the British Isles, really doesn’t help their survival as a species. You’d think being so ugly would help keep them OUT of peoples’ collections…
