Scientists have been puzzling over Oumuamua ever since the mysterious space object was observed tumbling past the sun in late 2017. Given its high speed and its unusual trajectory, the reddish, stadium-sized whatever-it-is had clearly come from outside our solar system. But its flattened, elongated shape and the way it accelerated on its way through the solar system set it apart from conventional asteroids and comets.

Now a pair of Harvard researchers are raising the possibility that Oumuamua is an alien spacecraft. As they say in a paper to be published Nov. 12 in The Astrophysical Journal Letters, the object “may be a fully operational probe sent intentionally to Earth vicinity by an alien civilization.”

The researchers aren’t claiming outright that aliens sent Oumuamua. But after a careful mathematical analysis of the way the interstellar object sped up as it shot past the sun, they say Oumuamua could be a spacecraft pushed through space by light falling on its surface — or, as they put it in the paper, a “lightsail of artificial origin.” (source)

Do you ever have that moment when a kid is looking at you and you realize that they’re looking at you as a grown up? Then its like no child im a children too, dont. Im sorry my outward appearance confuses you.

The moment in my life when I realized that 95% of adults are just freaked out teenagers in older bodies trying desperately to hide the fact that they don’t really know or understand what’s going on was probably the most important realization I’ve ever had

From now on solarpunk is officially a pro-GMO movement

Imagine street lights that are self-constructing, self-repairing, self-replicating, solar-powered, and carbon-negative because they’re just bioluminescent trees

Imagine fibrous plants that grow super-strong spider silk. Plants that grow as fast as bamboo but as strong as steel

Imagine medicine coming in fruit instead of pills. Oh you want to transition? Here, take this HRT shrub. Put it on your windowsill, water it daily and throw some compost at it every once in a while, and eat one berry per day

Imagine crops that are more nutritious, disease- and pest-resistant, and grow in harsher climates and soil conditions, helping to provide more reliable food to impoverished peoples with no downside whatsoever oh wait we already have those don’t we

We can’t have rad forest cities full of dope biotech if we’re too scared to let people do the research that’ll lead to that. Science has spoken: the fear is unjustified, and GMOs are safe. Let’s embrace them!

From now on? I thought we already were! 😬

So here’s an interesting little bit of biotech that’s being worked on to help combat food insecurity… 

Errr, first off, a little background? Plants have three different types of photosynthesis, based on the biochemical pathways the plant uses to capture CO₂ and make sugars for energy. The most common one is C3 photosynthesis, and it’s very old. This kind of photosynthesis probably evolved sometime in the mesozoic era, back when there were still dinosaurs wandering around.

Another type is C4 photosynthesis, which is a more recently evolved pathway. C4 carbon fixation is a lot more efficient, provides plants with more energy, and captures more CO₂. It evolved in environments with lots of light, so it’s common in warm parts of the world. In fact, C4 photosynthesis is so efficient that even though only about 5% of plants use it, they account for about 23% of the carbon fixation of all terrestrial plants!

C4 is the pathway used by sugarcane, which is what gives sugarcane one of the highest photosynthetic efficiencies of any plant. It’s also the pathway used by maize (corn) and sorghum (a popular grain in parts of Africa).

Anyway, that brings me to the genetic modification part.

After corn, the second most widely eaten food crop in the world is rice, but rice evolved to use the older C3 pathway. Some researchers are trying to change this by genetically modifying rice so it uses the more efficient C4 pathway instead.

The modified rice would theoretically be able to give higher crop yields, and do so using fewer nutrients and resources. As an added bonus, it would also help remove excess CO₂ from the atmosphere. The efforts are being coordinated by the International Rice Research Institute, who’ve received millions of dollars in donations towards the project – they’re the same organisation behind the golden rice project which was about making rice more nutritious for people affected by food scarcity.

Anyway tl;dr science is cool, genetic modification is a good thing, and it can be used to help end world hunger.

As someone who originally trained as a social historian of the Medieval Period, I have some things to add in support of the main point.  Most people dramatically underestimate the economic importance of Medieval women and their level of agency.  Part of the problem here is when modern people think of medieval people they are imagining the upper end of the nobility and not the rest of society. 

Your average low end farming family could not survive without women’s labour.  Yes, there was gender separation of labour.  Yes, the men did the bulk of the grain farming, outside of peak times like planting and harvest, but unless you were very well off, you generally didn’t live on that.  The women had primary responsibility for the chickens, ducks, or geese the family owned, and thus the eggs, feathers, and meat.  (Egg money is nothing to sneeze at and was often the main source of protein unless you were very well off).  They grew vegetables, and if she was lucky she might sell the excess.  Her hands were always busy, and not just with the tasks you expect like cooking, mending, child care, etc.. As she walked, as she rested, as she went about her day, if her hands would have otherwise been free, she was spinning thread with a hand distaff.  (You can see them tucked in the belts of peasant women in art of the era).  Unless her husband was a weaver, most of that thread was for sale to the folks making clothe as men didn’t spin.  Depending where she lived and the ages of her children, she might have primary responsibility for the families sheep and thus takes part in sheering and carding.  (Sheep were important and there are plenty of court cases of women stealing loose wool or even shearing other people’s sheep.)  She might gather firewood, nuts, fruit, or rushes, again depending on geography.  She might own and harvest fruit trees and thus make things out of that fruit.   She might keep bees and sell honey.  She might make and sell cheese if they had cows, sheep, or goats.  Just as her husband might have part time work as a carpenter or other skilled craft when the fields didn’t need him, she might do piece work for a craftsman or be a brewer of ale, cider, or perry (depending on geography).  Ale doesn’t keep so women in a village took it in turn to brew batches, the water not being potable on it’s own, so everyone needed some form of alcohol they could water down to drink.  The women’s labour and the money she bought in kept the family alive between the pay outs for the men as well as being utterly essential on a day to day survival level.

Something similar goes on in towns and cities.  The husband might be a craftsman or merchant, but trust me, so is his wife and she has the right to carry on the trade after his death.

Also, unless there was a lot of money, goods, lands, and/or titles involved, people generally got a say in who they married.  No really.  Keep in mind that the average age of first marriage for a yeoman was late teens or early twenties (depending when and where), but the average age of first marriage for the working poor was more like 27-29.  The average age of death for men in both those categories was 35.  with women, if you survived your first few child births you might live to see grandchildren.

Do the math there.  Odds are if your father was a small farmer, he’s been dead for some time before you gather enough goods to be marrying a man.  For sure your mother (and grandmother and/or step father if you have them) likely has opinions, but you can have a valid marriage by having sex after saying yes to a proposal or exchanging vows in the present (I thee wed), unless you live in Italy, where you likely need a notary.  You do not need clergy as church weddings don’t exist until the Reformation.  For sure, it’s better if you publish banns three Sundays running in case someone remembers you are too closely related, but it’s not a legal requirement.  Who exactly can stop you if you are both determined?

So the less money, goods, lands, and power your family has, the more likely you are to be choosing your partner.  There is an exception in that unfree folk can be required to remarry, but they are give time and plenty of warning before a partner would be picked for them.  It happened a lot less than you’d think.  If you were born free and had enough money to hire help as needed whether for farm or shop or other business, there was no requirement of remarriage at all.  You could pick a partner or choose to stay single.  Do the math again on death rates.  It’s pretty common to marry more than once.  Maybe the first wife died in childbirth.  The widower needs the work and income a wife brings in and that’s double if the baby survives.  Maybe the second wife has wide hips, but he dies from a work related injury when she’s still young.  She could sure use a man’s labour around the farm or shop.  Let’s say he dies in a fight or drowns in a ditch.  She’s been doing well.  Her children are old enough to help with the farm or shop, she picks a pretty youth for his looks instead of his economic value.  You get marriages for love and lust as well as economics just like you get now and May/December cuts both ways.

A lot of our ideas about how people lived in the past tends to get viewed through a Victorian or early Hollywood lens, but that tends to be particularly extreme as far was writing out women’s agency and contribution as well as white washing populations in our histories, films, and therefore our minds eyes.

Real life is more complicated than that.

BTW, there are plenty of women at the top end of the scale who showed plenty of agency and who wielded political and economic power.  I’ve seen people argue that the were exceptions, but I think they were part of a whole society that had a tradition of strong women living on just as they always had sermons and homilies admonishing them to be otherwise to the contrary.  There’s also a whole other thing going on with the Pope trying to centralized power from the thirteenth century on being vigorously resisted by powerful abbesses and other holy women.  Yes, they eventually mostly lost, but it took so many centuries because there were such strong traditions of those women having political power.

Boss post! To add to that, many historians have theorised that modern gender roles evolved alongside industrialisation, when there was suddenly a conceptual division between work/public spaces, and home/private spaces. The factory became the place of work, where previously work happened at home. Gender became entangled in this division, with women becoming associated with the home, and men with public spaces. It might be assumable, therefore, that women had (have?) greater freedoms in agrarian societies; or, at least, had (have?) different demands placed on them with regard to their gender.

(Please note that the above historical reading is profoundly Eurocentric, and not universally applicable. At the same time, when I say that the factory became the place of work, I mean it in conceptual sense, not a literal sense. Not everyone worked in the factory, but there is a lot of literature about how the institution of the factory, as a symbol of industrialisation, reshaped the way people thought about labour.)

I am broadly of that opinion.  You can see upper class women being encouraged to be less useful as the piecework system grows and spreads.  You can see that spread to the middle class around when the early factory system gears up.  By mid-19th century that domestic sphere vs, public sphere is full swing for everyone who can afford it and those who can’t are explicitly looked down on and treated as lesser.  You can see the class system slowly calcify from the 17th century on.

Grain of salt that I get less accurate between 1605-French Revolution or thereabouts.  I’ve periodically studied early modern stuff, but it’s more piecemeal.

I too was confining my remarks to Medieval Europe because 1. That was my specialty.  2. A lot of English language fantasy literature is based on Medieval Europe, often badly and more based on misapprehension than what real lives were like.

I am very grateful that progress is occurring and more traditions are influencing people’s writing.  I hate that so much of the fantasy writing of my childhood was so narrow.

Historically Authentic Sexism in Fantasy. Let’s Unpack That.

Wanna reblog this because for a long time I’ve had this vague knowledge in my head that society in the past wasn’t how people are always assuming it was (SERIOUSLY VICTORIANS, THANKS FOR DICKING WITH HOW WE VIEW EVERYTHING HISTORICAL). I get fed up with people who complain about fantasy stuff, claiming “historical accuracy” to whine about ethnic diversity and gender equality and other cool stuff that lets everyone join in the fun, and then I get sad because the first defence is always “it’s fantasy, so that doesn’t matter.”

I mean, that’s a good and valid defence, but here you have it; proof fucking positive that historical accuracy shows that equality and diversity are not new ideas and if anything BELONG in historical fiction. As far as I can tell, most people in the past were too bloody busy to get all ruffled up about that stuff; they had prejudices, but from what little I know the lines historically drawn in the sand were in slightly different places and for different reasons. (You can’t trust them furrigners. It’s all pixies and devil-worship over there).

So next time someone tells you that something isn’t “historically accurate” because it’s not racist/sexist/any other form of bigotry for that matter-ist enough for their liking, tell them to shut the hell up because they clearly know far less about history than they do about being an asshole.

Awesome.

Also an important thing to note for the people who like to think “back when we were cavemen men were in charge” if you actually look at human biology that doesn’t stack up. In social mammals, the only ones who undergo menopause are those with matriarchal groups. Menopause allows older females to take a break from breeding and looking after young and solely focus on being a leader and looking after the social group. If we stop looking at historical evidence through the lens of “men are physically stronger cuz testosterone so they must have been in charge” we might make more sense of the lives our ancestors lived. (Also physical strength doesn’t always mean leadership, even in the animal kingdom. Look at ants for a great example. Majors serve a certian role in the colony where their strength is required. But that doesn’t mean they’re in charge)
