Particle Fever is on Netflix
I repeat, Particle Fever is on Netflix
Go watch the documentary about the most complicated machine ever build by mankind to discover a particle that gives mass to the universe. If not for that then watch it in respect of the countless hours put in from many different disciplines coming together. If not for that then watch it in protest of America canceling the project, show that CERN matters, promote the material made from it. Go watch Particle Fever!

Here’s an endearing new story for the Department of Unexpected Interspecies Friendship. It’s a couple years old, but no less touching for being a bit dated. Meet Suryia the Orangutan and Roscoe the Bluetick Coonhound, an improbable pair who’ve been inseparable ever since they met at The Institute of Greatly Endangered and Rare Species (TIGERS) in Myrtle Beach, South Carolina. It’s the same endangered wildlife reserve that’s home to another Bubbles and Bella, another awesome and unlikely pair of pals.

Suryia and Roscoe first met in 2008 soon after Roscoe first appeared at the reserve and starting following TIGERS staff members as they walked home from work.

He was immediately spotted by the orangutan, who ambled over to make friends. Dr Bhagavan Antle, the reserve’s founder, said: ‘Roscoe looked really thin and a little lost so we fed him and took care of him. He followed us through the gate and ran over and found Suryia. As soon as he saw Roscoe, Suryia ran over to him and they started playing.

'Dogs are usually scared of primates, but they took to each other straight away. We made a few calls to see if he belonged to anyone and when no one came forward, Roscoe ended up staying.'

In 2011 Dr. Antle published a book of photographs which, entitled Suryia and Roscoe: The True Story of an Unlikely Friendship, shows the ape and pup enjoying each other’s company at the wildlife reserve.

"Science, then, is not like the onion in the often used analogy of stripping away layer after layer to get at some core, central, fundamental truth. Rather it’s like the magic well: no matter how many buckets of water you remove, there’s always another one to be had. Or even better, it’s like the widening ripples on the surface of a pond, the ever larger circumference in touch with more and more of what’s outside the circle, the unknown. This growing forefront is where science occurs… It is a mistake to bob around in the circle of facts instead of riding the wave to the great expanse lying outside the circle."

Stuart Firestein, from Ignorance: How It Drives Science

I was reminded of this quote, which sums up the driving force of the scientific process better than just about anything I’ve ever read, today after watching the latest Vlogbrothers video, in which Hank Green channels his inner Socrates:

"I know one thing, that I know nothing."

Watch Hank admit to being a towering mountain of ignorance (something we should all admit) below…

The spotted handfish (Brachionichthys hirsutus), an amazing creature that walks the ocean floor, is a rare Australian fish from the family Brachionichthyidae. It is classified as Critically Endangered on the IUCN Red List 2002. is the first Australian marine species to be threatened with extinction.

The greatest threats to the handfish appear to be siltation and invasive species. The Derwent Estuary where the fish lives is highly urbanised and industrialised, and a range of marine pests have been introduced through shipping.  One key pest is the Northern Pacific Seastar (Asterias amurensis), a particularly large and voracious predator that is now abundant in the estuary. Studies by CSIRO show that the seastars eat the stalked ascidians that the handfish use to attach their eggs.

Like I always say, a fish with a hand is better than two in the bush

The recent release of “Dawn of the Planet of the Apes" reminded me of one of my favorite ape vs. man films – this 1932 video that shows a baby chimpanzee and a baby human undergoing the same basic psychological tests.

Its gets weirder – the human baby (Donald) and the chimpanzee baby (Gua) were both raised as humans by their biological/adopted father Winthrop Niles Kellogg.  Kellogg was a comparative psychologist fascinated by the interplay between nature and nurture, and he devised a fascinating (and questionably ethical) experiment to study it:

Suppose an anthropoid were taken into a typical human family at the day of birth and reared as a child. Suppose he were fed upon a bottle, clothed, washed, bathed, fondled, and given a characteristically human environment; that he were spoken to like the human infant from the moment of parturition; that he had an adopted human mother and an adopted human father.

First, Kellogg had to convince his pregnant wife he wasn’t crazy:

 …the enthusiasm of one of us met with so much resistance from the other that it appeared likely we could never come to an agreement upon whether or not we should even attempt such an undertaking.

She apparently gave in, because Donald and Gua were raised, for nine months, as brother and sister. Much like Caesar in the “Planet of the Apes” movies, Gua developed faster than her “brother,” and often outperformed him in tasks. But she soon hit a cognitive wall, and the experiment came to an end. (Probably for the best, as Donald had begun to speak chimpanzee.)

Squishy Robots

"A new phase-changing material built from wax and foam developed by researchers at MIT is capable of switching between hard and soft states."

MIT researchers are trying to change the paradigm of your typical robot by mimicking organic substances. The idea is that the robot should be soft to conform to a particular environment, and interact with humans, though rigid enough to actually do a procedure. They can achieve this by applying heat at particular points to deform the object, then applying coolness to make the object rigid again. 

"Robots built from this material would be able to operate more like biological systems with applications ranging from difficult search and rescue operations, squeezing through rubble looking for survivors, to deformable surgical robots that could move through the body to reach a particular point without damaging any of the organs or vessels along the way."

The last gif is a example of bendable articulation. :D

While today may belong to the 45th anniversary of the Apollo 11 lunar landing, it’s important not to forget another important anniversary for NASA - the landing of the Viking 1 spacecraft on Mars!On July 20th, 1976, the Viking 1 lander separated from the orbiter and touched down at Chryse Planitia, a flat lowland region in the northern hemisphere of Mars. Immediately following touchdown, the lander made history by taking and transmitting the first complete photograph taken from the surface of Mars. The image (http://goo.gl/6C5L6m) was of the Viking 1 lander’s foot as an indication of how far it had sunk into the Martian surface. Between itself and its companion, Viking 2, this historic photograph was just the first of more than 50,000 images taken from the Martian surface, as well as from orbit, and transmitted back to Earth.What makes Viking 1 especially worth noting is that it was not only the first attempt by the United States at landing on Mars, but it was also the first spacecraft to successfully do so and perform its mission. While the Soviet Mars 3 mission was the first to achieve a soft landing of a spacecraft on Mars it stopped transmitting data 15 seconds after landing. During those few seconds of transmission, it sent the first partial photograph taken from the surface of Mars although nothing was identifiable in it.During its operation on the Martian surface, Viking 1 became the record holder for longest Mars surface mission at 2307 days, until Mars Rover Opportunity took the record in 2010.To read more about Viking 1:http://goo.gl/NOxjpMhttp://goo.gl/iKPlJ6http://goo.gl/6klaq9

Today we remember the first moonwalk on July 20 1969.

todaysdocument:

Apollo 11 Astronauts Neil Armstrong and Buzz Aldrin make the first moonwalk, on July 20, 1969.

In these clips they can been seen planting the U.S. Flag on the lunar surface and experimenting with various types of movement in the Moon’s lower gravity, including loping strides and kangaroo hops.

"A scientific colleague tells me about a recent trip to the New Guinea highlands where she visited a stone age culture hardly contacted by Western civilization. They were ignorant of wristwatches, soft drinks, and frozen food. But they knew about Apollo 11. They knew that humans had walked on the moon. They knew the names of Armstrong and Aldrin and Collins. They wanted to know who was visiting the moon these days." - Carl SaganAfter traveling four days and more than 238,900 miles, the Lunar Module Eagle began its descent to the surface of the Moon. Very early on, however, it became clear to Aldrin and Armstrong that their telemetry was incorrect as they recognized lunar landmarks were being passed too early. At approximately 6,000 miles above the surface, numerous guidance computer program alarms distracted the crew as they communicated with flight controllers. Mission Control engineers soon reassured the Eagle to continue with the descent as it was determined that their system was being overloaded with extra tasks not necessary to land on the Moon. After looking out of the window a few moments later, Armstrong was forced to take semi-manual control as he noticed that the navigational systems were guiding them towards an area comprised of boulders and an uneven landing surface. This manual override would require Aldrin to call out velocity and altitude data before landing fuel ran out. After a somewhat frantic period, the Lunar Module safely landed on the moon on July 20th, 1969 — with about 25 seconds of fuel remaining.As an estimated 600 million people watched, Neil Armstrong became the first ambassador of the planet Earth to walk on another world. For over 2.5 hours, he and Buzz Aldrin captured the imagination of our species as they performed various scientific and geological experiments. Along with planting an American flag, a commemorative plaque marking this monumental human achievement was mounted to the Apollo 11 Lunar Module — and remains as a relic of humanity’s first journey on the Moon.“We came in peace for all mankind. That statement really to me was a very symbolic one — not just of our mission, but of the entire Apollo effort.” - Buzz Aldrin, Apollo 11 Lunar Module PilotApollo 11 was arguably our most exciting adventure, and over the span of three years, NASA sent a total of 12 astronauts to explore the Moon. However, not since 1972 have human beings been beyond low-Earth orbit.
