Boy: Ops, I ran over our nursery teacher Ms. Heinrich.

Girl: And I ran over stupid Tom.

Text under picture: Adults often misinterpret children's play situations.

I'm a squid biologist on a mission

To bring squid facts to you. To your friends. To your neighbors. To some random dude named Brad who you've never met.

How? The Squid Facts Project. It's a street art campaign and hotline that texts folks squid facts!

Only snag in this hair-brained plan is that texting people is kiiinda expensive. So! I teamed up with Philly artist Corey Danks to sell shirts to keep the hotline running. Every one of those shirt dollars helps deliver squid facts to people.

Like, over 70,000 people over the last year!!! Isn't that wild?

So anyway. Get a shirt. They're cool, *and* they keep people learning about squid. It's a beautiful thing.

Also, the backs have the squid facts hotline on them so by wearing these you're helping people learn about squid too.

If you can't buy one, give us a reblog. I run a small science education nonprofit called Skype a Scientist, we're scrappy but trying so hard!!

“My journey has been very free. I’ve been able to work in different parts of the world and on projects that don’t necessarily obey a typical journey of a person that wants to be famous or work in film. I want young actors to know you don’t have to follow a set line to have a career. Sometimes the line is drawn for actors from the English language. But in my case I can reinvent myself all the time.” — Gael García Bernal (Total Film, 07/2021)

Okay, look, I've been in college for two years and my Biology professor has pretty significantly rooted this educational science game called Labster into her course.

I was not expecting to be playing Portal all day for school.

Yeah, this is a full, 360 sci-fi free roam lab environment that you can pretty much do whatever you want in. You know those cruddy flash game experiments you used to do in middle school? Those are a thing of the past.

And check this: the entire lab is being run by this super cool AI droid named Dr. One

She floats around and directs you around the lab depending on the lesson you're taking and sounds eerily similar to GLaDOS. It turns out that Dr. One also has a lore page and that she was created originally for "unethical purposes."

Also, this environment is extremely detailed and even runs shaders and ambient occlusion in your web browser.

That's pretty nuts, considering the only time we ever see these things are built into genuine video games, not a web browser lab. It runs incredibly smoothly on my GTX 1050.

This is insanely impressive and I actually enjoyed my homework today. 10/10, would play this in my free time.

Woman Who Can Smell Parkinson’s Helps Develop Test

Joy Milne, 72, from Perth, Scotland, has a hyper-sensitive sense of smell, allowing her to be able to smell Parkinson’s disease, which progressively damages parts of the brain over many years.

She discovered her unusual ability when her late husband, Les, developed a different odour when he was 33. She described it as a ‘musky aroma’. That was 12 years before he was diagnosed with Parkinson’s. Les, who was a doctor, was determined to research the link between odour and Parkinson’s, and contacted Dr Tilo Kunath at the University of Edinburgh, who paired up with Professor Perdita Barran to begin the research. They determined that the reasons for a change in the scent of a person suffering the disease is due to a chemical change of the skin oil (sebum).

In the preliminary sessions, Milne was asked to smell T-shirts worn by people who had Parkinson’s and those who did not. She successfully identified all of the Parkinson’s patients, but told researchers that a member of the control group, a non-Parkinson’s patient, did smell like the disease. 8 months later, they were diagnosed with the disease.

Now, a team of researchers at the University of Manchester have developed a simple test involving a cotton bud swiped down the back of the neck that can identify those with Parkinson’s. The molecules on the cotton bud can be examined using mass spectrometry, which helps the diagnosis. This is a huge leap forward, as there is no definitive test for Parkinson’s, and a diagnosis is based on symptoms and medical history. Currently, there are no cures for Parkinson’s, but an early diagnosis can help begin the treatment early, lessening the speed of the deterioration.

Milne says she can sometimes smell that a person has Parkinson’s when walking down the street, but has been told by medical ethicists that she cannot tell them. She is continuing to work with scientists to see if she can smell other diseases, like cancer or TB, and hopes that one day her talent can be considered normal diagnosis.

Watch what happens to Germs when you wash your hands with Soap at microscopic level. 🔬 The Soap molecules surround germ cells and disrupt their cell walls, causing them to burst.

Germ cells are surrounded by a cell wall that protects them from the environment. This cell wall is made up of a layer of peptidoglycan, which is a polymer of amino acids and sugars. Soap molecules are made up of two parts: a hydrophobic (water-fearing) tail and a hydrophilic (water-loving) head. When soap is added to water, the hydrophobic tails group together and the hydrophilic heads face outward, forming micelles. These micelles can surround germ cells and the hydrophobic tails can then disrupt the cell walls, causing the cells to burst.

The hydrophobic tails of the soap molecules can disrupt the cell wall in two ways. First, they can bind to the peptidoglycan molecules and weaken the bonds between them. Second, they can create holes in the cell wall. Once the cell wall is disrupted, the germ cells lose their internal contents and die.

It is important to note that soap only works to kill germ cells that are surrounded by a cell wall. Germ cells that do not have a cell wall, such as viruses, are not affected by soap.

The size of the soap micelles is important. Micelles that are too small will not be able to surround the germ cells. Micelles that are too large will not be able to penetrate the cell walls.

The concentration of soap is also important. A higher concentration of soap will be more effective at killing germ cells.

The temperature of the water can also affect the effectiveness of soap. Soap is more effective at killing germ cells in warm water than in cold water.

I hope this post has helped you understand the importance of handwashing and why doctors always ask you to do it regularly. Washing your hands with soap and water for at least 20 seconds is one of the best ways to prevent the spread of germs and stay healthy. So please, wash your hands often and help keep yourself and others safe!

Thank you for reading this post. I hope you found it informative and helpful. Please share it with your friends and family so they can learn about the importance of handwashing too. 😊🙏
