Hey so

the last time I reblogged this post right before I got a great job, in a permanent work-from-home position, with benefits, retirement, and a salary literally 3x what I was making before, doing something I really like.

So you know.

This might be the real one, y’all.

Seeing a comet in Glacier’s dark night skies

Right now, in the northern hemisphere, we have the chance to see something that, once it’s gone, won’t reappear for 6,800 years!

Comet NEOWISE (discovered by NASA’s Near-Earth Object Wide-field Infrared Survey Explorer) is visible now for a short time, and bright enough to see without a telescope. Through about July 23, you can catch it if you look northwest just after sunset. Get tips from NASA here: https://www.nasa.gov/feature/how-to-see-comet-neowise

Stargazers in the park have been treated to views of the comet the past couple of nights. Being able to see this comet in Glacier is a reminder of the value of naturally dark night skies. Without significant light pollution, it’s amazing what you can experience at night!

In 2009, scientists from the National Park Service Night Sky Division measured the quality of Glacier’s night skies at Logan Pass using a measurement called the Anthropogenic Light Ratio. This value compares total sky brightness to natural nighttime light levels. The lower the ALR value, the higher the quality of night sky conditions. The ALR at Logan Pass was 0.17, meaning that the sky there is estimated to be 17 percent brighter than a natural light level. This is considered a very good quality of night sky.

In 2017, Waterton-Glacier was granted a provisional Gold Tier designation as an International Dark Sky Park, a designation reserved for places with exemplary night skies.

What are some of the ways you’ve been able to appreciate dark night skies?

Women In History

I grew up believing that women had contributed nothing to the world until the 1960′s. So once I became a feminist I started collecting information on women in history, and here’s my collection so far, in no particular order.

Lepa Svetozara Radić (1925–1943) was a partisan executed at the age of 17 for shooting at German soldiers during WW2. As her captors tied the noose around her neck, they offered her a way out of the gallows by revealing her comrades and leaders identities. She responded that she was not a traitor to her people and they would reveal themselves when they avenged her death. She was the youngest winner of the Order of the People’s Hero of Yugoslavia, awarded in 1951

23 year old Phyllis Latour Doyle was British spy who parachuted into occupied Normandy in 1944 on a reconnaissance mission in preparation for D-day. She relayed 135 secret messages before France was finally liberated.

Catherine Leroy, War Photographer starting with the Vietnam war. She was taken a prisoner of war. When released she continued to be a war photographer until her death in 2006.

Lieutenant Pavlichenko was a Ukrainian sniper in WWII, with a total of 309 kills, including 36 enemy snipers. After being wounded, she toured the US to promote friendship between the two countries, and was called ‘fat’ by one of her interviewers, which she found rather amusing.

Johanna Hannie “Jannetje” Schaft was born in Haarlem. She studied in Amsterdam had many Jewish friends. During WWII she aided many people who were hiding from the Germans and began working in resistance movements. She helped to assassinate two nazis. She was later captured and executed. Her last words were “I shoot better than you.”.

Nancy wake was a resistance spy in WWII, and was so hated by the Germans that at one point she was their most wanted person with a price of 5 million francs on her head. During one of her missions, while parachuting into occupied France, her parachute became tangled in a tree. A french agent commented that he wished that all trees would bear such beautiful fruit, to which she replied “Don’t give me any of that French shit!”, and later that evening she killed a German sentry with her bare hands.

After her husband was killed in WWII, Violette Szabo began working for the resistance. In her work, she helped to sabotage a railroad and passed along secret information. She was captured and executed at a concentration camp at age 23.

Grace Hopper was a computer scientist who invented the first ever compiler. Her invention makes every single computer program you use possible.

Mona Louise Parsons was a member of an informal resistance group in the Netherlands during WWII. After her resistance network was infiltrated, she was captured and was the first Canadian woman to be imprisoned by the Nazis. She was originally sentenced to death by firing squad, but the sentence was lowered to hard lard labor in a prison camp. She escaped.

Simone Segouin was a Parisian rebel who killed an unknown number of Germans and captured 25 with the aid of her submachine gun. She was present at the liberation of Paris and was later awarded the ‘croix de guerre’.

Mary Edwards Walker is the only woman to have ever won an American Medal of Honor. She earned it for her work as a surgeon during the Civil War. It was revoked in 1917, but she wore it until hear death two years later. It was restored posthumously.

Italian neuroscientist won a Nobel Prize for her discovery of nerve growth factor. She died aged 103.

EDIT

jinxedinks added: Her name was Rita Levi-Montalcini. She was jewish, and so from 1938 until the end of the fascist regime in Italy she was forbidden from working at university. She set up a makeshift lab in her bedroom and continued with her research throughout the war.

Part 2

Annie Jump Cannon was an american astronomer and, in addition to possibly having one of the best names in history, was co-creator of one of the first scientific classification systems of stars, based on temperature.

Melba Roy Moutan was a Harvard educated mathematician who led a team of mathematicians at NASA, nicknamed ‘Computers’ for their number processing prowess.

Joyce Jacobson Kaufman was a chemist who developed the concept of conformational topology, and studied at Johns Hopkins University before it officially allowed women entry in 1970.

Vera Rubin is an astronomer and has co-authored 114 peer reviewed papers. She specializes in the study of dark matter and galaxy rotation rates.

Mary Sherman Morgan was a rocket scientist who invented hydyne, a liquid fuel that powered the USA’s Jupiter C-rocket.

Chien-Siung Wu was a physicist who worked on the Manhattan Project, as well as experimental radioactive studies. She was the first woman to become president of the American Physical Society.

Mildred Catherine Rebstock was the first person to synthesize the antibiotic chloromycetin.

Ruby Hirose was a chemist who conducted vital research about an infant paralysis vaccine.

Hattie Elizabeth Alexander was a pediatrician and microbiologist who developed a remedy for Haemophilus influenzae, and conducted vital research on antibiotic resistance.

Marie Tharp was a scientist who mapped the floor of the Atlantic Ocean and provided proof of continental drift.

Mae Jamison is an astronaut who holds a degree in chemical engineering from Stanford University and was the first black woman in space.

Ada Lovelace was a mathematician and considered to be the world’s first computer programmer.

Patricia E Bath is ophthalmologist and the inventor of the Laserphaco Probe, which is used to treat cataracts.

Barbara McClintock won a Nobel prize for her discovery that genes could move in and between chromosomes.

That’s it for now, part three will be on its way. (Josephine Baker was requested in the first installment, just know I did not forget her! She’s in a different folder, titled ‘famous people you didn’t know were complete badasses, and she, along with Hedy Lamar and Audrey Hepburn will be in the next installment :) )

Part 3

Josephine Baker, though today remembered for her dancing, singing, and larger than life personality, actually played a significant role in WWII. She joined Women’s Auxiliary of the Free French Air Force, got her pilot’s license in 1933, and by 1944 she raised 3,143,000 francs for the war effort. She entertained the troops, which was a doubly whammy of justice. She refused to entertain segregated troops, so the French military was forced to integrate the troops for all her performances. She also smuggled secret messages in her music across countless borders.

Audrey Hepburn is known as one of the most beautiful and talent actresses of the 1950′s, but her contributions to the world started far before her first film and continued until well after her cinematic heyday. In WWII stricken Austria, Audrey, then an aspiring ballerina, would give secret ballet performances to raise money for the Austrian resistance. She even helped smuggle secret messages for the resistance. On one such occasion, she was stopped by an enemy soldier. He asked her what she was doing and she, pretending not to understand, presented him with a bouquet of wildflowers she’d been absentmindedly picking. She was let go and the message was delivered safely. It was her experience in the war which would later prompt her to become one of the founders of UNICEF.

Hedy Lamarr was an actress well known for her piercing gaze and deadpan wit. What she’s less known for is being a brilliant mathematician who invented the frequency hopping spread spectrum. Without her invention, we wouldn’t have bluetooth or wifi.

Ching Shih was one of the world’s most successful pirates. At the death of her (pirate) husband, the former prostitute took command of his ships and started her pirating career. At the height of her career she commanded 1800 ships and more than 80,000 male and female pirates. She became powerful enough to challenge every empire’s naval forces in the world and her Red Flag Fleet was feared from the Chinese coast to Malaysia. Unable to defeat her, the Chinese government caved and offered her amnesty. She surprised everyone by taking it and became one of the few pirates in history to retire. She also took care of her crew even after her retirement; most of Ching’s pirates were pardoned. She died a respectable millionaire.

Sophie School was an active member of the White Rose non-violent resistance group in WWII Germany. In 1943 she, along with her brother and the rest of the White Rose were arrested for passing out leaflets encouraging passive resistance. She and her brother were beheaded by guillotine just a few hours later. Her last words were “How can we expect righteousness to prevail when there is hardly anyone willing to give himself up individually to a righteous cause. Such a fine, sunny day, and I have to go, but what does my death matter, if through us, thousands of people are awakened and stirred to action?”

(Written by Emporer-of-nerds) Constance Markievicz (was a) Very important figure in the Irish independence movement, first woman elected to the British House of Commons, and one of the first women to hold a cabinet position in government (Minister for Labour of the Irish Republic (which was a short-lived revolutionary state predating the current Ireland/Éire))!

Lady Mary Wortley Montagu was an English ambassador to Turkey in the early 1700s, and documented her experience carefully. When she saw the Turkish perform an early method of small-pox vaccination, she urgently wrote home. She is responsible for the first variolation small-pox vaccinations in Europe.

Marie Curie is fairly well known. Unfortunately she’s often known as the ‘assistant’ to her husband. She was a pioneering physicist and chemist, who’s work with radiation was groundbreaking. She was the first woman to win a Nobel prize and the only one to win one in two fields for her discovery of polonium and uranium. It’s also notable that she was the first woman in Europe to receive a doctorate degree. Her discoveries made the x-ray machine possible, and Curie immediately put it to work. She invented a small, mobile type of x-ray machine and worked with her daughter at casualty collection points in WWI, using the machine to locate shrapnel and bullets in wounded soldiers. She died of pernicious anemia, a result of years of radioactive exposure. Many of her notebooks are still too radioactive to be read.

Margherita Hack was an Italian astrophysicist and became administrator of the Trieste Astronomical Observatory, bringing it to renowned respect and fame. She was a prolific science writer and was awarded the Targa Giuseppe Piazzi for the scientific research, and later the Cortina Ulisse Prize for scientific dissemination. Asteroid 8558 Hack, discovered in 1995, was named in her honor.

(This installment was a little all over the place as far as achievements go, and short, since it was mostly requests! Hypatia of Alexandria was also requested but she, along with Sappho and others, are getting their own installment. The next installment will center around women of the literary world!)

Great respect for this!

Note that there were many many more, both before and after photography was invented.

Don’t ever let some fuckboy tell you that women just cleaned and cooked until very recently.

New material produces cheap hydrogen

By Idha Valeur

Producing hydrogen for storage of renewable energy could become cheaper and more efficient with a new material discovered by chemistry researchers at Queensland University of Technology (QUT), Australia.

According to Professor Anthony O’Mullane, professor at QUT’s Science and Engineering Faculty, the new composite material developed in collaboration with PhD student Ummul Sultana, enables electrochemical water to split into hydrogen and oxygen using cheap and easily available elements as catalysts. Instead of using precious and expensive metals, like iridium oxide, ruthenium oxide and platinum the research team found that they could use alternatives such as cobalt and nickel oxide and only a fraction of gold nanoparticles – to save a few pennies and the environment. These two elements make for a stable bi-functional catalyst that split water and produce hydrogen with no emissions.

‘From an industry point of view, it makes a lot of sense to use one catalyst material instead of two different catalysts to produce hydrogen from water,’ O’Mullane said.

The hydrogen could be used in fuel cells, according to O’Mullane.

O’Mullane, said, ‘Fuel cells are a mature technology, already being rolled out in many makes of vehicle. They use hydrogen and oxygen as fuels to generate electricity – essentially the opposite of water splitting.

‘With a lot of cheaply ‘made’ hydrogen we can feed fuel cell-generated electricity back into the grid when required during peak demand or power our transportation system and the only thing emitted is water.’

The paper, Gold Doping in a Layered Co-Ni Hydroxide System via Galvanic Replacement for Overall Electrochemicals was published in Advanced Functional Materials.

The Transgender Scientists That Changed the World of Science.

As this week is Transgender Week of Awareness (12th - 19th November) I felt it was a good time to bring awareness to some of the more well-known transgender scientists that changed science. Trans people have always been apart of scientific discovery but like most minorities within STEM have struggled to gain recognition for their contributions.

Alan Hart (1890–1962) | Epidemiology

A Yale-trained epidemiologist, radiologist and physician, Hart one of the first trans men in the US to undergo a hysterectomy and live openly as a man, taking testosterone treatments when they became available after World War II. Hart also become a prominent figure in the fight against tuberculosis, which at the time was the leading cause of death in Europe and the US. He graduated with a medical degree in 1912 and later in 1928 received a master’s degree in radiology. He eventually became an expert on tubercular radiology and published several articles on X-ray medicine and its use in the detection of tuberculosis and went on to gain another master’s degree in public health in 1948.

Hart then served as the director of hospitalization and rehabilitation at the Connecticut State Tuberculosis Commission and continued to dedicate his professional life to tuberculosis research.

Ben Barres (1954 - 2017) | Neuroscience

Barres was the first openly transgender scientist in the National Academy of Sciences in 2013 and talked openly about his experience of sexism pre-transition and advocated for better gender equality within science. Barres research focused on the interaction between neurons and glial cells in the nervous system. Barres showed that the gila, which at the time were often dismissed by neurologists as simple the support structure for the brain, had important functions in helping neurons to mature and producing connections between memory and learning functions. This discovery revolutionised neruobiologists understanding of the brain.

Barres also went on to mentor many young scientists and repeatedly spoke about the systemic barriers and biases that kept marginalised groups such as women, poc and LGBT people, from succeeding or furthering their careers and research within science.

Sophie Wilson | Computer Science

Sophie Wilson is a British computer scientist who is known for designing the Acorn Micro-Computer, the first computer sold by Acorn Computers. She also designed the instruction set of ARM processor which is used in 21st-century smartphones and is considered one of the most important woman in tech history.

Lynn Ann Conway | Computer Science

A pioneer of a number of technological advancements and inventions, Conway is an American computer scientist, electrical engineer and inventor. She first worked at IMB in the 1960′s designing a super computer and is credited with the invention of generalised dynamic instruction handling, now used by modern computer processors in order to improve performance. She was fired after she revealed her intention to transition and was denied access to her children.

After she transitioned she restarted her career and authored the Mead & Conway revolution in VLSI design, that was considered groundbreaking work that quickly become a standard textbook in chip design.

Joan Roughgarden | Biology

known for her critical studies on Charles Darwin’s theory of sexual selection and LGBT biology, Roughgarden is an American ecologist and evolutionary biologist, having published over 180 scientific articles and books. Roughgarden has carried out ecological studies on barnacles, Caribbean lizards but is most known for her published book critiquing Darwin’s sexual selection theory based on the fact it fails to answer and consider animals which do not follow traditional sex roles of intrasexual and intersexual selection. She was met with bitter and vitrioli criticism from other scientists for publishing such views, to which she was not surprised.

Roughgarden went on to publish a second book further pointing out over 26 phenomena which the current sexual-selection theory does not explain, and instead suggests the social-selection theory. She continues to make analytical studies that social selection is a more credible explanation.

Six Science-y Shipments Sent to the Space Station

Northrop Grumman launched its Cygnus spacecraft into orbit to the International Space Station at 4:01 a.m. EST on Nov. 17 from Wallops Flight Facility in Virginia. Cygnus launched on an Antares rocket carrying crew supplies, equipment and scientific research to crewmembers aboard the station. The spacecraft is named after NASA astronaut and U.S. Navy officer John Young, who walked on the Moon during Apollo 16 and commanded the first space shuttle mission. Throughout his lifetime, Young logged 835 hours in space over the course of six missions.

Antares launched the S.S. John Young from the Mid-Atlantic Regional Spaceport’s Pad-0A on Wallops Island, carrying tons of cargo, including scientific investigations that will study 3D printing and recycling, cement solidification, and crystals that may fight Parkinson’s disease.

Here’s a look at six science-y experiments and research this mission will deliver to the space station.

1. 3D printing and recycling

Refabricator demonstrates an integrated 3D printer and recycler for the first time aboard the space station.

It recycles waste plastic materials into high-quality 3D-printer filament, which could enable sustainable fabrication, repair, and recycling on long-duration space missions.

2. Sensory input in microgravity

Changes in sensory input in microgravity may be misinterpreted and cause a person to make errors in estimation of velocity, distance or orientation.

VECTION, a Canadian Space Agency (CSA) investigation, examines this effect as well as whether people adapt to altered sensory input on long-duration missions and how that adaptation changes upon return to Earth.

3. Solidifying cement in space

The MVP-Cell 05 investigation uses a centrifuge to provide a variable gravity environment to study the complex process of cement solidification, a step toward eventually making and using concrete on extraterrestrial bodies.

4. From stardust to solar systems

Much of the universe was created when dust from star-based processes clumped into intermediate-sized particles and eventually became planets, moons and other objects. Many questions remain as to just how this worked, though.

The EXCISS investigation seeks answers by simulating the high-energy, low gravity conditions that were present during formation of the early solar system. Scientists plan to zap a specially formulated dust with an electrical current, then study the shape and texture of pellets formed.

5. Growing crystals to fight Parkinson’s disease

The CASIS PCG-16 investigation grows large crystals of an important protein, Leucine-rich repeat kinase 2, or LRRK2, in microgravity for analysis back on Earth.

This protein is implicated in development of Parkinson’s disease, and defining its shape and morphology may help scientists better understand the pathology of the disease and develop therapies to treat it. Crystals of LRRK2 grown in gravity are too small and too compact to study, making microgravity an essential part of this research.

6. Better gas separation membranes

Membranes represent one of the most energy-efficient and cost-effective technologies for separating and removing carbon dioxide from waste gases, thereby reducing greenhouse gas emissions. CEMSICA tests membranes made from particles of calcium-silicate (C-S) with pores 100 nanometers or smaller. Producing these membranes in microgravity may resolve some of the challenges of their manufacture on Earth and lead to development of lower-cost, more durable membranes that use less energy. The technology ultimately may help reduce the harmful effects of CO2 emissions on the planet.

Reliably simulating polyurethane foams

Car seats, mattresses and insulation materials are often made of polyurethane foams. The foaming process of the liquid polymer emulsions is complex. Fraunhofer researchers are now able to simulate the foaming behavior and reliably characterize the material. This also works with composite materials in which the plastic foams are combined with textile structures.

Polyurethane foams – PU foams for short – play a big role in our everyday lives, even if we are generally not aware of them. We sit and lie on them every day: car seats and mattresses, for example, are made of soft PU foams. Hard PU foams, on the other hand, are used among other things for insulation materials in buildings. Predicting the properties of foams and characterizing them is very complex – experimental analyses often lead to false parameters.
