cells are living

This is why girls are so much more employable than young men in all the shitty, less-than-subsistence-level service jobs they’re trying to cram young people into across Europe and America. Girls are better at pleasing other people and plastering on the pretty grin even when we’re screaming inside. That’s what being a girl is.

Girls are better at this sort of labour, often called ‘emotional labour’, not because there’s anything in the meat and matter of our living cells that makes us naturally better but because we’re trained to it from birth. Trained to make other people feel good. Trained to serve the coffee, fill in the forms, organise the parties and wipe the table afterwards. Trained to be feisty, if we must, but not strong. To be bubbly, not funny. You must at no stage appear to have a body that functions in a normal human way, that pisses and shits and sweats and farts and falters. Decorate the prison of your body. Make yourself useful. Shut up and smile.

Science in Space!

What science is headed to the International Space Station with Orbital ATK’s cargo resupply launch? From investigations that study magnetic cell culturing to crystal growth, let’s take a look…

Orbital ATK is targeted to launch its Cygnus spacecraft into orbit on April 18, delivering tons of cargo, supplies and experiments to the crew onboard.

Efficacy and Metabolism of Azonafide Antibody-Drug Conjugates in Microgravity Investigation

In microgravity, cancer cells grow in 3-D. Structures that closely resemble their form in the human body, which allows us to better test the efficacy of a drug. This experiment tests new antibody drug conjugates.

These conjugates combine an immune-activating drug with antibodies and target only cancer cells, which could potentially increase the effectiveness of chemotherapy and potentially reduce the associated side-effects. Results from this investigation could help inform drug design for cancer patients, as well as more insight into how microgravity effects a drug’s performance.

Genes in Space

The Genes in Space-2 experiment aims to understand how the regulation of telomeres (protective caps on the tips of chromosomes) can change during spaceflight. Julian Rubinfien, 16-year-old DNA scientist and now space researcher, is sending his experiment to space as part of this investigation. 

3-D Cell Culturing in Space

Cells cultured in space spontaneously grow in 3-D, as opposed to cells cultured on Earth which grow in 2-D, resulting in characteristics more representative of how cells grow and function in living organisms. The Magnetic 3-D Cell Culture for Biological Research in Microgravity investigation will test magnetized cells and tools that may make it easier to handle cells and cell cultures.

This could help investigators improve the ability to reproduce similar investigations on Earth.

SUBSA

The Solidification Using a Baffle in Sealed Ampoules (SUBSA) investigation was originally operated successfully aboard the space station in 2002. 

Although it has been updated with modernized software, data acquisition, high definition video and communications interfaces, its objective remains the same: advance our understanding of the processes involved in semiconductor crystal growth. 

Space Debris

Out-of-function satellites, spent rocket stages and other debris frequently reenter Earth’s atmosphere, where most of it breaks up and disintegrates before hitting the ground. However, some larger objects can survive. The Thermal Protection Material Flight Test and Reentry Data Collection (RED-Data2) investigation will study a new type of recording device that rides alongside of a spacecraft reentering the Earth’s atmosphere. Along the way, it will record data about the extreme conditions it encounters, something scientists have been unable to test on a large scale thus afar.

Understanding what happens to a spacecraft as it reenters the atmosphere could lead to increased accuracy of spacecraft breakup predictions, an improved design of future spacecraft and the development of materials that can resist the extreme heat and pressure of returning to Earth. 

IceCube CubeSat

IceCube, a small satellite known as a CubeSat, will measure cloud ice using an 883-Gigahertz radiometer. Used to predict weather and climate models, IceCube will collect the first global map of cloud-induced radiances. 

The key objective for this investigation is to raise the technology readiness level, a NASA assessment that measures a technology’s maturity level.

Advanced Plant Habitat

Joining the space station’s growing list of facilities is the Advanced Plant Habitat, a fully enclosed, environmentally controlled plant habitat used to conduct plant bioscience research. This habitat integrates proven microgravity plant growth processes with newly-developed technologies to increase overall efficiency and reliability. 

The ability to cultivate plants for food and oxygen generation aboard the space station is a key step in the planning of longer-duration, deep space missions where frequent resupply missions may not be a possibility.

Watch Launch!

Orbital ATK and United Launch Alliance (ULA) are targeting Tuesday, April 18 for launch of the Cygnus cargo spacecraft to the International Space Station. Liftoff is currently slated for 11 a.m. EST.

Watch live HERE.

You can also watch the launch live in 360! This will be the world’s first live 360-degree stream of a rocket launch. Watch the 360 stream HERE.

Daisy Ridley on porgs, Kylo Ren and more 'Star War: The Last Jedi' teasers

USA Today

Daisy Ridley can’t escape her Star Wars fame, even as a mysterious murder suspect riding the opulent 1930’s train in Murder on the Orient Express.

While filming Murder (in theaters now), director Kenneth Branagh offered to let Ridley use alightsaber in a key scene (she declined) and co-star Josh Gad peppered her with Star Wars questions offset on video, even pulling in Judi Dench for one Force interrogation.

We, too, had a few queries as Ridley gets set to ride as Rey again in Star Wars: The Last Jedi (opening Dec. 15). Here’s what we learned.

Ridley is so pro-porgs (Rey not so much).

The free world fell in love when the chubby porg creatures made a screaming debut in The Last Jedi trailer last month. It hit Ridley, too. She lists a porg toy as one of her prized possessions.

“It’s bringing a lot of pleasure right now,” says Ridley, calling the character “adorable” and “hilarious.”

The love affair started on set with the goofy looking puppet, operated by the same crew who handle droid BB-8. “It’s wonderful to be working around practical things on set that have such personality,” says Ridley,

But Rey won’t fall for the creature’s charms. “Rey, honestly, is too wrapped up in her own journey to pay attention to porgs,” says Ridley. “Which is a sad thing.”

Snoke will provide the worst kind of ‘test’ for Rey.

Supreme Leader Snoke (Andy Serkis) ain’t pretty and acts worse. “He looks mental. Snoke is an evil guy, if you can call him a guy,” says Ridley.

Last Jedi’s trailer shows Rey screaming under Snoke torture. Ridley says the torture scenes were long enough to leave her hoarse. “It was painful. My throat hurt after that one,” says Ridley.

“Snoke is one of those tests for Rey,” she adds. “And when I say testing, it’s the worst use of testing ever.”

Watch for Kylo Ren and Rey time.

Is there something special going on with Rey and the Dark Side-dwelling Kylo Ren (Adam Driver)? The two seem to have a special connection in the trailers.

Ridley choses her words carefully.

“These are two people who represent two very different sides of life, good and evil,” she says. “That’s going to be explored more in this.”

Luke Skywalker is annoyed with Rey.

Rey is expecting Luke Skywalker to be thrilled to get his lightsaber back in Last Jedi. But he’s not happy to see her. “She thinks there’s going to be a warm welcome. But Luke went to this island to get away and he doesn’t want to be disturbed,” says Ridley.

Don’t fret. Skywalker takes “a tremendous journey from the beginning of the relationship to ultimately where they end up in the film.” Our personal theory: He had coffee.

Judi Dench really doesn’t know squat about Star Wars.

Dench seems to be a Star Wars nut, grilling Ridley in one of Gad’s videos on fan-minutia such as whether she had been tested for midi-chlorians, living cells in tune with the Force (from Episode I – The Phantom Menace).

She played the part well, but Dench doesn’t have Force fever.

“She was like, 'Medi…Midi-chlorians, what is that?’ Josh and I had to explain,” says Ridley, who says she had Gad had to stifle their laughs when cameras rolled.

Dench did ask Ridley to shoot a personal Star Wars video for her grandson. “Obviously he’s very interested.”

abortions

I don’t believe in abortions. and never well. a cell is a living thing and i well not be the one to kill what i have taken the mistake of making. and that is why i’m having the baby i have now. Cells are the building blocks of the living world. Living things as diverse as bacteria, Archean, algae, fungi, protozoans, animals, and plants all consist of one or more cells. Cells are made up of components that help living things to eat, respire, excrete wastes, and perform all of the necessary functions of life. sorry but that clump of cells your aborting ya they are living.
