Huge Raven Pair Chilling

I used to think crows and ravens were the same thing - and then I saw a raven. These things are SO big.

Cape Cod Canal Centennial!

The Cape Cod Canal first opened to limited traffic 100 years ago on July 29, 1914.  Located at the base of Cape Cod where it joins the Massachusetts mainland, the canal runs 17.5 miles from Cape Cod Bay to Buzzards Bay and enables nautical traffic to cut at least 65 miles off the trip around the hazardous outer shore of the Cape.

Find more photos and records on the Cape Cod Canal

Text 29 Jul 98,191 notes why are bats stigmatized as being creepy?

I mean

look at these things

image

they’re like tiny

image

fluffy

image

dragons

image

but instead of breathing fire they squeak and cuddle 

image

in caves

image

and leaves

image

and they have funny ears and noses

image

I mean really

image

bats are amazing

In the fifth picture, the bats have White-nose Syndrome. If you’d like to learn more about this disease decimating North American bat populations, check out these links:

http://www.nwhc.usgs.gov/disease_information/white-nose_syndrome/

https://www.whitenosesyndrome.org/

In addition to being adorable, bats are critical in maintaining cave ecosystems, which house many other threatened species. They save the U.S. agricultural industry approximately 4 billion dollars in pest control every year, and reduce the need for toxic pesticides. In rainforests, these animals are important pollinators and seed dispersal agents that keep the forest regenerating. 

If you want to help bats, read up about them, educate others, volunteer for bat organizations, or donate money to great charities like Bat Conservation International. 

I hope everyone comes to love bats as much as I do!

Photo 29 Jul 19 notes Fruit colours evolved to please picky birds, study says

Tropical Asian birds have a penchant for red and black—a proclivity that likely prompted jungle plants to sprout fruit in these colours, scientists said on Thursday. It has long been suspected that an abundance of red and black fleshy fruits in nature was partly inspired by a pigment preference of the keen-eyed birds that eat them and spread the seeds.
A team in China decided to test the theory by determining once and for all whether birds do have colour favourites. To eliminate possibly confounding influences of smell, shape or taste, the team manufactured artificial fruits from a mixture of apple, pear, banana, wheat and corn flour rolled into small balls and dyed black, red, yellow, green or blue using tasteless food colouring. They then put the fruit balls in front of different species of bulbul and barbet birds native to tropical Xishuangbanna in southwest China.
The birds, both wild-caught and hand-reared, were left to choose for themselves what they wanted to eat. All favoured red fruit, followed by black, the scientists found, and all avoided green ones, whose seeds in nature are generally dispersed by insects and other non-avian animals. The results were similar in experiments with real fruit.
"The preferences were constant over time, supporting the hypothesis that bird colour preferences are a contributing factor driving fruit colour evolution in tropical Asia," the team wrote in the Nature journal Scientific Reports.

Quote 29 Jul 40 notes
Today only a tiny minority of outsiders see Israelis as victims. The true victims, it is now widely accepted, are the Palestinians. Indeed, Palestinians have now displaced Jews as the emblematic persecuted minority: vulnerable, humiliated and stateless. This unsought distinction does little to advance the Palestinian case any more than it ever helped Jews, but it has redefined Israel forever. It has become commonplace to compare Israel at best to an occupying colonizer, at worst to the South Africa of race laws and Bantustans. In this capacity Israel elicits scant sympathy even when its own citizens suffer: Dead Israelis - like the occasional assassinated white South African in the apartheid era, or British colonists hacked to death by native insurgents - are typically perceived abroad not as the victims of terrorism but as the collateral damage of their own government’s mistaken policies.

Differences between male and female skulls.

Some of this stuff overlaps into ancestry as well but it’s a good quick guide 

In GENERAL, males have more pronounced, robust cranial features. It is important to remember that there is a lot of overlap in reality, and many skulls are ambiguous or have a percentage of uncertainty!

Note also that the image shows the two skulls from slightly different angles (and possibly different lighting) that emphasize certain features more in one than the other.

View of Toledo by El Greco.

El Greco cultivated other genres more rarely…. His two landscapes, View of Toledo (c. 1610; New York, Met.) and View and Plan of Toledo (Toledo, Casa & Mus. El Greco), are also late works of c. 1610. In these El Greco is preoccupied with the means of representing what is perceived as well as an emblematic sense of the urban landscape and a zenithal projection of the city, a combination that was advanced in the representation of urban topography. It is possible that in Toledo and Madrid these works influenced interest in still-life and in landscape, genres that had, almost exclusively, been orientated towards a naturalistic type of formal structure.

Quote 29 Jul 11 notes

This weekend, Vice discovered an unusual, additional role for two FISC judges—stakeholder. According to 2013 financial disclosures obtained by the website, FISC Judge Susan Wright and FISC Judge Dennis Saylor each owned Verizon stock. Wright purchased (Scribd) $15,000 or less on October 22 and Saylor collected (Scribd) less than $1,000 from his stock in 2013. (As Vice notes, “the precise amount and value of each investment is unclear—like many government ethics disclosures, including those for federal lawmakers, investments amounts are revealed within certain ranges of value.)

There is an ethics law for federal judges that, among other things, requires judges to avoid cases where they have a financial stake or where they may act in bias. This scenario isn’t quite that clear-cut. While FISC absolutely ruled on situations involving Verizon, Vice points out FISC proceedings are ex parte. Telecoms may absolutely have a stake in these FISC rulings, but they aren’t an active party for the NSA requests FISC rules on.

The website pointed out that FISC judges in the past have also owned telecom stock, though Verizon is the only named telecom in the NSA leaks to comply so far. Vice’s requests for comment to the direct judges went unanswered as expected, but legal ethicists speaking to the site recommended the best solution is simply steering clear of such gray situations in the first place.

Voting by members has reached the limit of its usefulness. We are picking winners and losers, when it is clearly obvious that witches can only be found by dunking them in water. If they float they’re a witch. If they don’t, installing a pool will allow us to retrieve the non-witch before he or she drowns.
