Earth is made up of two planets fused together, new research suggests
RIP, planet buddy.
By Fiona MacDonald

Astronomers investigating how the Moon formed have found evidence that it was produced after a small planet smashed headfirst into Earth around 4.5 billion years ago. And research suggests that this collision was so violent that the ‘planetary embryo’ that hit us, called Theia, ended up fusing with both Earth and the Moon as a result.

The idea that the Moon was formed as part of a Solar System crash isn’t new, but scientists in the past have proposed that Theia simply side-swiped Earth, blasting the Moon into orbit and then continuing off into space. Now new research by a team at the University of California, Los Angeles, suggests that Theia actually never left us.

Crazy Lace Agate

This stone comes from limestone rocks in the Mexican states of Chihuahua and Durango. Agates are silicate minerals, formed from silica that dissolves in water as it percolates through a rock and then precipitates that silica once it finds an open cavity. This agate forms in veins or fractures in the limestone, creating layers that wind back and forth depending on the path of the vein.

Hello Studyblrs!!

I decided to make a Masterpost dedicated specifically to students doing the Leaving Cert because like me, many irish students struggle in class or have some terrible teachers and are forced to look elsewhere for notes and info. This post has direct links to notes and information, all of which is on the leaving cert course. If you are not a LC student but you study some of these subjects, you may find these notes useful also, depending on your exam board. Let me know if you would like me to add any other subjects or specific topics to the list. 

Enjoy Studying!

The physics of the perfect chocolate for Valentine’s Day

“The first thing to understand is that chocolate, like carbon or ice, can form crystals in a number of different fashions. While carbon can form diamond, graphite, nanotubes, buckminsterfullerenes or even pencil lead depending on how it bonds together, chocolate can take on six different distinct crystalline structures, depending on how the chocolate molecules assemble next to one another. If you want to sound fancy, this means that chocolate is a six-phase polymorphic crystal.”

One of the most iconic associations with Valentine’s Day is chocolate. And not just any chocolate, mind you, but good-quality chocolate, with a creamy, silky-smooth texture, a firm but shiny structure, and an even, rich consistency and taste throughout. Perhaps surprisingly, there’s a rich and complex science behind it. Chocolate can come in six different crystalline structures, and by properly controlling the temperature, you can ensure that yours comes out absolutely perfect, thanks to a little physics.


(7/100) // 2.12.16 // I’m having a little bit of a re-cap study session. My biology professor talks way too fast, so I need to break everything down to fully understand everything. Of course, I had to do it at the cutest coffee shop ever. I love today. Today is a good day. :)


This One’s For You ~

As we edge ever closer to 6,500 followers, we wish to thank all of you who find our nerdy little library blog worth pursuing. We are also mindful that there is a certain die-hard contingency that like or reblog our posts on a regular basis. We are deeply appreciative of your support, so for you we want to do something special. On a regular basis, we will select an avid follower and create a post just for them.

This post on the Women of Chemistry is for our friends @othmeralia, the Tumblr blog of the Othmer Library of Chemical History at the Chemical Heritage Foundation in Philadelphia. Thanks othmeralia for always being there! And where would Tumblr be without their sterling posts on chemical history and other sciencey (and even non-sciencey) things? If you’re not following @othmeralia, then you have a big hole in your life.

These images are from a 1946 United States Department of Labor, Women’s Bureau bulletin, The Outlook for Women in Chemistry, from the series The Outlook for Women in Science. We note that the Othmer Library also holds this bulletin. It also seems, othmeralia,  that this publication has not yet been the subject of your Women in Science series. So, now you don’t have to do one, you can just reblog ours!

So, for all you do, this post’s for you, @othmeralia!!

[26/100] days of productivity: 02.12.2016:

I tried working on some essays, but it’s a Friday and I just want to relax!!! Tomorrow and Sunday will be work-my-ass-off-day because I have a math exam on Tuesday, and that = mental breakdown. 

I looked at my hands today and realized how…beat up they are. I mean, I have no nails right now (which is kinda hard to pull tape off vials), my skin is visible dry and cracked, and they just look terrible. If a meninist was to approach me, he would say I have hands like a man and I shouldn’t be working in a lab. Well, I work in a chemistry lab and solvents like methanol and acetonitrile have a tendency to dry out skin and wearing nitrile gloves also doesn’t help.

But I realized, my hands do beautiful work. Sure, they look like shit and I cannot have pretty, professionally done nails for a while, but they fix HPLC columns, they pipette 12 assay plates like no one’s business in like 2 hours, and can hold like twenty sample vials without dropping them. The point is that my fellow science ladies can understand my pain in that we try to uphold our feminine traits (or we try), but in the end we are doing our jobs and sometimes we won’t look super gorgeous (according to societal standards). I think all us women look damn good in a white lab coat!
