Phineas Gage is one of the most famous patients in the history of neuroscience. He was 25 years old when he experienced a serious accident at his work place, where a tamping iron was shot through his head - entering under his eye socket at exiting through the top of his head - after an explosive charge went off. The tamping iron was over a metre long, and after exiting Gage’s head landed 25m away. 

Initially Gage collapsed and went into minor convlusions, but recovered quickly and was able to speak after a few minutes. He walked with little assistance to an ox-cart and was brought to a nearby physician. Initially the physician did not believe his story because he was in such good condition, but was convinced when: 

Mr. G. got up and vomited; the effort of vomiting pressed out about half a teacupful of the brain, which fell upon the floor.

Gage exhibited a number of dramatic behavioural changes following the accident. Harlow, the physician who initially treated Gage, described this change “He is fitful, irreverent, indulging at times in the grossest profanity (which was not pre­vi­ous­ly his custom), manifesting but little deference for his fellows, impatient of restraint or advice when it conflicts with his desires”. However the surgeon Henry Jacob Bigelow described his condition as improving over the course of recovery, stated he was “quite recovered in faculties of body and mind”. This may have been early evidence of neural plasticity. This recovery was also reported by a physician who knew Gage while he lived in Chile, who described his ability to hold on a full time job as a Concord coach driver, a job that required exceptional social skills.

Gage’s neurological deficits following his traumatic brain injury is thought to have been exaggerated and distorted over the course of history, to the point that he is often portrayed as a ‘psychopath’. Scientific analysis of the historical accounts of Gage’s life following his accident, namely by the psychologist Malcolm Macmillan, find that these distorted accounts are most likely untrue, and that Gage made a very good recovery.

Post-mortem analysis of the Gage case concluded that it was the left frontal lobe that was damaged in the accident, although further neurological damage may have resulted from infection. Combined examination of the Phineas Gage case with the other famous cases of Tan and H.M. have concluded that social behaviour, memory, and language are dependent on the co-ordination of a number of different brain areas rather than a single region.

This is a scientific Illustration of my scorpion that I ordered online! The process consisted of rehydrating the specimen as well as pinning it into place on a piece of foam board. The end product was completed using carbon dust as well as carbon pencil to achieve the rich dark values within the subject! hope you guys enjoy!

19th century sketches of fishes from the seas surrounding China and Japan. 

The fish in the top image (the drawing clearly has taken some inspiration from the Chinese dragons) belongs to the stargazer family. Stargazers have their eyes and mouths on top of their heads. As the stargazers bury in the bottom of the sea, the top facing mouth and eyes allows them to ambush the prey quickly and unnoticed. This particular stargazer drawn here belongs to Uranoscopus genera, which is also capable of producing electric shocks.

Pachamama- Divine Feminine 

Pachamama is a goddess of the ancient indigenous people of the Andes. Pachamama is usually translated as Mother Earth, but a more literal translation would be “Mother World”. She was a fertility goddess who presided over planting and harvesting but who also caused earthquakes.

Neutron star smash-up shows us first light alongside a gravity wave

For the first time ever we’ve detected light from a gravitational wave event, after two incredibly dense neutron stars smashed together, an exciting discovery that  helps scientists understand some of the most violent and powerful collisions in the universe. 

Neutron stars are the crushed remnants of massive stars which exploded as supernovas. What used to be the core lingers behind as the smallest and densest stars in our universe, a ball just a few miles across but containing more mass than our Sun. Just one teaspoon’s worth of neutron star would weigh a billion tonnes. 

Earlier this month the Nobel prize in Physics was awarded for the first detections of gravity waves, ripples through spacetime. But those waves were caused by black holes merging and so no light, or electromagnetic radiation, was observed because famously light can’t escape black holes. 

Astrophysicists believed that when two neutron stars collided there would be visible light alongside gravity waves, as predicted from Einstein’s theories. But until they saw it happen, no-one knew for sure. 

On August 17 2017 this all changed. 

Not only were were gravity waves picked up from a galaxy 130 million light years away, but so were range of light-based measurements from the merger of two neutron stars as they smashed together.  

These included a burst of gamma rays, light from a type of radioactive explosion called a kilo-nova and, later, X-rays from the gamma ray burst afterglow. 

Thousands of scientists around the world have been working furiously ever since to present the initial findings, published today. 

Together these measurements confirm a host of theoretical predictions, and will greatly advance our understanding of what exactly goes on when these incredible events occur, such as the conditions in which some of the heaviest elements including gold and platinum, are formed.

In one sense the we’ve been lucky to capture all this data in such rich detail because we could have been waiting decades for a neutron star merger close enough to Earth to be detected. But, on the other hand, scientists have been working for decades to get to the point where we have good enough equipment to be able to make the most of it. It’s a case of chance meeting preparation, and it’s paid of for the scientific community.

Phenology- the study of cyclic and seasonal natural phenomena, especially in relation to climate and plant and animal life (from Oxford Dictionary). 

Because of the climate change the patterns of many phenological activities in animals and plants are changing. Earlier spring means earlier snowmelt and earlier blossoming of flowers. While this may not seem a bad thing, it may well have some dramatic effects because not all organisms adapt to phenological changes at the same rate. For example, the snowshoe hares have white fur in winter and grey in summer to camouflage themselves against predators. With the snow melting earlier, however, the white fur makes hares particularly easy to spot in a muddy spring environment for the predators, causing a fast decline in hare population.

A photo of the green alga Volvox globator from the Dodel-Port Atlas, circa 1880. 

Volvox globator exists as a spherical colony of individual single-celled organisms, each with two whip-like appendages called flagella that V. globator uses to propel itself around. The cells are stuck together by thin strands of cytoplasm, allowing them to move in concert to direct the colony’s motions.

anonymous asked:

Can we see that moment in PT when Ness and Lucas dance together?^~^

Um of course you can my friend

Did you know that this is a scientific image showing the exact moment where Ness goes from “Maybe bisexual, I’m not sure” to “Oh shit I’m almost as gay as my best friend” 

THE “ADHESIVE” HAIRS ON A GECKO’S TOE
Nature News & Comment

This microscopic image shows the forest-like arrangement of hairs on a gecko’s toe that gives the animal its gravity-defying ability to scurry across ceilings.

Each foot has hundreds of thousands of these hairs, called setae, which fray into smaller hairs with split ends called spatulae. The hairs’ strong grip has inspired the design of medical adhesives.

This image was taken by Dennis Kunkel, a photomicrographer in Hawaii. It is part of Life: Magnified, an exhibition of scientific images on display at Washington Dulles International Airport’s Gateway Gallery from June to November.

What dark structures arise from the Pelican Nebula? Visible as a bird-shaped nebula toward the constellation of a bird (Cygnus, the Swan), the Pelican Nebula is a place dotted with newly formed stars but fouled with dark dust. These smoke-sized dust grains formed in the cool atmospheres of young stars and were dispersed by stellar winds and explosions. Impressive Herbig-Haro jets are seen emitted by a star on the right that is helping to destroy the light year-long dust pillar that contains it. The featured image was scientifically-colored to emphasize light emitted by small amounts of ionized nitrogen, oxygen, and sulfur in the nebula made predominantly of hydrogen and helium. The Pelican Nebula (IC 5067 and IC 5070) is about 2,000 light-years away and can be found with a small telescope to the northeast of the bright star Deneb.
