I'm going to be like the guy below and periodically (I mean every Wednesday) from now on, I'll endeavour to share posts of interest/news over all things chemistry.
(http://i.imgur.com/HarvZij.jpg)
Starting off with this week we have (although some of these may be slightly older than a week):
Metallic Hydrogen disappearance (Independent) In fact, it was a physicist that managed to get that into physical form. :)
Computers predicting the smell of compounds (C&EN)
Basically shows how smelling things for science provides great information.
Komodo dragons could be the key to solving antibiotic resistance (Science Alert)
Focuses on komodo dragon blood (which has some wacky proteins in it), which could lead to curing people with illnesses that aren't currently treatable by conventional antibiotics.
One for the cats lovers out there *cough*Joseph41*cough*
: There's lots of chemicals found on indoor cats (Science Daily)Photoluminescent compounds (Science Daily) One for those who like pretty coloured (and fluoro) chemicals.
A good read for biochemists: A better way to detect the stiffness of cancer cells (Phys.org)
And for now:

Awwww yeah Physicists unite!!Sorry to say but it is chemistry > physics ;)
Great thread insanipi!!
But thanks :-*
If you keep this up I'm going to have to put a Kanye meme in my sig saying insanipi is the best mod of all timeHahaha, I'll have the popcorn out, just in case. ;)

Faster NMR? Say no more! Enhanced NMR can reveal chemical structures faster than your average NMR!
Summary
There has been developments in research by scientists that dramatically increase the sensitivity of NMR. This increased sensitivity will allow the analysis chemical structures in mere minutes- in comparison to months (or years). This new idea involves the use of Dynamic Nuclear Polarisation (DNP) and short microwave radiation pulses.
Want airtight pharma patents? This computer program will help you!
Summary
Synthesis pathways for making life-saving medications and other pharmaceutical compounds are among the most carefully protected trade secrets in the pharmaceutical industry. Researchers have unveiled computerised methods (or programs) to suggest only synthetic pathways that won't use those pesky patent-protected aspects of essential drugs and compounds. The program is called Chematica- and could change the game as to how chemists treat intellectual property and patents.

I've been reading a lot of articles lately on creating innovative, reusable alternatives to things like plastic bags, etc. Also, there was the creation of plastic from fish (scales? don't remember), and a form of biodegradable plastic. I found this article, which involves a process of turning plant materials into biofuels. Based on the chem 3/4 textbook, I can see how expensive and time-consuming the creation of fuels, especially biofuels are. Hopefully more methods such as the one in the article can be created to increase worldwide use of biofuels and other renewable sources of energy.

In light of all the bushfires and drought occuring in the world, I asked a question. At first I thought it was a silly question, but I did find it super interesting to read about, so I thought I'd share it.
Why can't water be manufactured? After all, all you need is 2 hydrogen and 1 oxygen molecule. Easy enough right??
Nope, not really.

- Using very sophisticated microscopic techniques to see chemical bonds make and break
- Material characterisation can now pinpoint cement setting times
- A safer way of disposing of circuit boards has been developed (This is more material science than chemistry, but still interesting!)
- A new approach to sustainable building! (This is also more material science than chemistry, but still pretty cool!)

Here's some other news articles in the past week from Science Daily! :)Awesome chem news insanipi!
- Using very sophisticated microscopic techniques to see chemical bonds make and break
- Material characterisation can now pinpoint cement setting times
- A safer way of disposing of circuit boards has been developed (This is more material science than chemistry, but still interesting!)
- A new approach to sustainable building! (This is also more material science than chemistry, but still pretty cool!)
I particulalry found the imaging of chemical bonding quite interesting. It has been something i've wondered before - can you image a bond - however I had never looked into it, so this article has certainly answered that question of mine!
I am intersted to see how these forms of microscopy continue to develop and teach us more about how bonding works :)

"A leaf produces glucose and oxygen. We produce methanol and oxygen.".
The methanol can then be used for many different purposes.
Great work in hopes of lowering CO2 emissions.

Nobel Prize (Physiology or Medicine): Harvey Alter, Michael Houghton, Charles Rice (Hepatitis C virus discovery)
Nobel Prize (Chemistry): Jennifer Doudna and Emmanuelle Charpentier (CRISPR/Cas9)
Post by: keltingmeith on October 08, 2020, 04:25:53 am
Nobel Prize (Chemistry): Jennifer Doudna and Emmanuelle Charpentier (CRISPR/Cas9)
This is fucking ground-breaking.
No no - legit, this is a next level announcement, and I'm honestly surprised nobody's talking about this more???
Here's a list of all the times the recipients of a Nobel prize has gone to a panel that is exclusively female:
-Peace, 1905 - Bertha von Suttner
-Literature, 1909 - Selma Lagerlöf
-Chemistry, 1911 - Marie Curie
-Literature, 1926 - Grazia Deledda
-Literature, 1928 - Sigrid Undset
-Literature, 1938 - Pearl S. Buck
-Literature, 1945 - Gabriela Mistral
-Chemistry, 1964 - Dorothy Hodgkin
-Peace, 1976 - Betty Williams, Mairead Maguire
-Peace, 1979 - Mother Teresa
-Physiology, 1983 - Barbara McClintock
-Literature, 1991 - Nadine Gordimer
-Peace, 1992 - Rigoberta Menchú
-Literature, 1993 - Toni Morrison
-Literature, 1996 - Wisława Szymborska
-Peace, 2003 - Shirin Ebadi
-Literature, 2004 - Elfriede Jelinek
-Peace, 2004 - Wangari Maathai
-Literature, 2009 - Herta Müller
-Peace, 2011 - Ellen Johnson Sirleaf, Leymah Gbowee, Tawakel Karman
-Literature, 2013 - Alice Munro
-Literature, 2015 - Svetlana Alexievich
-Literature, 2018 - Olga Tokarczuk
-Chemistry, 2020 - Emmanuelle Charpentier, Jennifer Doudna
See it? I mean, ignoring the fact that the Nobel Prize has been going for more than a century and this list is disturbingly small. Hang on, it's probably hard when this list is almost EXCLUSIVELY Peace and Literature. Let me fix that:
-Chemistry, 1911 - Marie Curie
-Chemistry, 1964 - Dorothy Hodgkin
-Physiology, 1983 - Barbara McClintock
-Chemistry, 2020 - Emmanuelle Charpentier, Jennifer Doudna
How about now? That's right - this is the FIRST TIME that the Nobel prize has been awarded to panel of people who is exclusively female. Now we just need to wait for a sole woman/group of only women to get the economics and physics prizes...
