"I don’t think that everyone should become a mathematician, but I do believe that many students don’t give mathematics a real chance. I did poorly in math for a couple of years in middle school; I was just not interested in thinking about it.
I can see that without being excited mathematics can look pointless and cold. The beauty of mathematics only shows itself to more patient followers."

Jell-O-like Substance Attracts, Kills Cancer Cells

Chasing cancer cells with chemotherapy drugs can save lives, but there’s no guarantee that the treatment will kill every run-away cancer cell in the body.

What if, instead of hunting those metastatic cells, a treatment could lure them out of hiding — every last one of them — and eliminate them in one swift blow? Yong Wang, associate professor of bioengineering at Penn State, has created such a therapy — a tissue-like biomaterial that attracts cancer cells, like bits of metal to a magnet, and entraps them.

In February 1935, a chimpanzee at London Zoo called Boo-Boo gave birth to a baby daughter. A couple of months later, a little blonde-haired girl was given a soft-toy replica of the zoo’s new arrival to mark her first birthday. This was Jane Goodall’s first recorded encounter with a chimp.

Sweat-powered battery could charge your phone

A sweaty gym workout is not only good for your health - it could also energise your phone.

A tattoo that produces power from perspiration has been unveiled at the American Chemical Society meeting.

The biobattery is fuelled by lactate - which is naturally present in sweat after vigorous exercise.

It could soon power heart monitors, digital watches and eventually even smartphones, say scientists in California.”

Teen creates bio-plastic from banana peels

Sixteen-year-old Elif Bilgin of Turkey has developed a way to replace traditional petroleum-based plastic with banana peels.

The Turkish teen took home a US$50,000 prize for her project “Go Bananas!” Thursday after winning the second annual Scientific American Science in Action Award, associated with Google Science Fair.

“My project makes it possible to use banana peels, a waste material which is thrown away almost every day, in the electrical insulation of cables,” Bilgin said in a media statement.

“This is both an extremely nature-friendly and cheap process, which has the potential to decrease the amount of pollution created due to the use of plastics, which contain petroleum derivatives.”

Bilgin spent two years developing the bio-plastic, which does not decay. She said the process is so easy that it is possible to repeat at home, with special care taken for chemicals used in the production process.

In September, the teen will compete at Google’s California headquarters for the overall Google Science Fair prize for 15-to-16 year olds. She will also have access to a one-year mentorship.

Has anyone else noticed how many brilliant breakthroughs in science are coming from the minds of teenage girls the last few years? Between this story, the four girls in Nigeria who invented a generator that runs on urine, the California girl who invented a twenty-second cell phone charger… Who knows where we’d be today without the patriarchal interference of men, stealing or hiding the brilliance of women?

Our future is in the hands of teenage girls, and I for one feel really good about that.

When I was about 7 I wanted to invent a thing that purified water based off of fish gills. I went to the school library to do research like a good little inventor and one of my teachers asked me what I was doing, and then told me that there were some new barbie books in, and that I’d probably be better off with those.

Don’t forget the girl who invented a torch that’d light up just from the heat of your hands

basically everyone should stop s***ting on teenage girls because they do awesome things when you let them

or that one time a girl found the cure for cancer that we could be using in 15 years

Is that link to the girl who taught herself to code and created a program that can detect breast cancer more accurately than a mammogram?

also notable: it’s black and brown girls inventing all this world-changing stuff.

Scales

This is because Fahrenheit is based on a brine scale and the human body. The scale is basically how cold does it have to be to freeze saltwater (zero Fahrenheit) to what temperature is the human body (100-ish Fahrenheit, although now we know that’s not exactly accurate). Fahrenheit was designed around humans.

Celsius and Kelvin are designed around the natural world.

Celsius is a scale based on water. Zero is when water freezes, 100 is when water boils.

Kelvin uses the same scale as Celsius (one degree, as a unit, is the same between the two), but defines zero as absolute zero, which is basically the temperature at which atoms literally stop doing that spinning thing. Nothing can exist below zero Kelvin. It’s the bottom of the scale.

So.
Fahrenheit: what temperatures affect humans
Celsius: what temperatures affect water
Kelvin: what temperatures affect atoms

Why didn’t my science teachers ever see fit to toss off this little fact?

As some of you might already have guessed, I’m a fan of Japanese girl idols. One of the many, many idol groups in existence today in Japan is NMB48, a Osaka-based spin-off group of the (in)famous AKB48. NMB has a weekly show that’s surprisingly entertaining as well as educational called NMB to Manabu-kun, in which the members of NMB and a few comedians listen to guest lectures by experts in various fields.

Back on May 15th, the theme of the episode was pataphysics/the science of sci-fi. One of the topics of the lecture held by university professor Yanagita Rikao was the age-old question of "WHY ARE MAGICAL GIRLS NEVER ATTACKED WHILE TRANSFORMING???"

This was his answer, based on the magical girl series Futari wa Pretty Cure.

imageQuestion: The transformation scenes in Pretty Cure are very long, so why don’t the bad guys attack the girls in the meantime?

image"Even when I was little, I was thinking ‘Hey! Attack them now!’"

image"I found this odd as well, so I watched the transformation scene many times. And what I noticed is, when the Pretty Cures yell ‘Dual Aurora Wave!’ and transform, a rainbow-colored column of light shoots up from the ground, going BOOM!"

image"And then the Pretty Cures levitate, and go up into the air. Based on this, I believe the protagonists of Pretty Cure are being held up in the air by the power of light.”

image"When we think of light, we usually think it heats up things or lights up things. But in reality, light has the power to hold up things as well."

image"When the sun is beating down on us in the summer, the human body is being pressed downwards by the sun beams with a force of 2/100,000g.”

image"But this is only about a one-hundred of the weight of a mosquito, so no matter how hot it is, we don’t feel that sunlight is heavy."

image"So that means the light holding them up must be extremely strong. If we assume that the two Pretty Cures each weigh about 45kg and do some calculations…”

image"It means the light during the transformation must have the energy of 2,100,000,000kW per 1m2.”

image"While the entirety of power that Japan is capable of generating is only 100,000,000kW.”

image"So they’re using 21 TIMES the amount of energy the whole of Japan can generate.”

image"So what would happen if a bad guy jumped in to try to sabotage their transformation?"

image"He would EVAPORATE INSTANTLY.”

imageDEATH AWAITS ANYONE WHO DARES TO DISRUPT A PRETTY CURE TRANSFORMATION.

image"So this means the best thing to do would be to transform close to any bad guys."

image"Yes. They are the strongest while they transform, and are practically invincible.”

Fe Del Mundo

[x], [x], [x], [x]

Fe Del Mundo (1911-2011) was a Filipina pediatrician, and the first woman to be admitted into Harvard Medical School. (They mistook her gender on the application form, but her credentials were so good they decided not to send her back. She may also have been the first Asian to attend.)

As a child, she’d already decided she wanted to be a doctor for the poor - three of her eight siblings died when they were kids. After her medical studies, she returned home to the Philippines, only to be plunged into the devastation of the Japanese military occupation of World War Two.

She volunteered to care for kids in the internment camp and set up a hospital there, earning her the nickname “The Angel of San Tomás”. She ended up heading a new children’s hospital during the war, that later evolved into a full-scale medical centre.

After the war, she opened the country’s first pediatric hospital, did pioneering research into infectious diseases like dengue fever, advocated family planning (controversial due to her Catholicism) and invented a bamboo incubator to be used in rural villages. And she went on working as a pediatrician well into her nineties.

So don’t mess with women in STEM. There’s every chance they will outlive you.
