looks like someone got inspired by the ugly black coating on their stir bar after doing a reaction with Na or BuLi!

Main-Chain Ketone Installation in Polyethylene Chains: A Metal-Free Strategy toward Photodegradable Plastics Polyethylene with in-chain isolated ketones is an attractive target for achieving photodegradability while maintaining polyolefin material properties. This work reports a method to functionalize post-consumer polyethylene through radical C–H activation to install TEMPO functionalities and subsequent oxidation to obtain in-chain isolated ketones without compromising the polymer molecular weights. This process does not require metals, catalysts, or expensive reagents and allows tunable ketone incorporation up to 3Β molΒ %. The thermal and mechanical properties were investigated to demonstrate that the ketone-containing polyethylene could potentially work as a photodegradable alternative of existing polyethylene. Photodegradation of the ketone-containing polyethylene reveals a clear decrease in molecular weights and suggests random installation of functionalities. This approach enables the conversion of post-consumer polyethylene into ketone functionalized materials through simple chemical transformations.

It's a pink dinosaur! As a lady I was unable to resist buying it for myself due to the color, berry smell, and wanting to see dinosaur pictures when I shower in the morning.

It was way more sane than I expected, but if you want the typical Dave experience he was recently interviewed by Tucker Carlson...

In the first reaction scheme a cartoon chicken is being treated with chlorine. On the left side of the equation the chicken is saying β€œuck, uck, uck”. On the right aside it is saying β€œcluck cluck cluck”. In the second reaction scheme, the chicken is saying β€œuck uck uck”. It is treated with fluorine and there is a question mark on the right hand side of the equation asking what the chicken would be saying.

"Under the terms of the executive order, political appointees loyal to the president can willfully find justification to label any research finding as scientific misconduct"

This should terrify every single scientist in America.

Two possible reasons for this are:

1.) Women, POC and/or disabled people are more likely to do equity oriented work

2.) Women, POC and/or disabled people have been marked as DEI regardless of what they do

The government will try to point to the former reason when it is in reality the latter

I'm the 1st scientist in my family. My parents were amazed I could attend @caltech.edu, an elite private school, for my PhD studies FOR FREE. In fact, I was paid to become a PhD chemist. STEM is a pathway to a good career. I study TB- a disease that impacts millions. Fund NIH.

Sourdough bread and traditional loaves have high hydration and little or no fat or sugar, so they can take the higher temperatures, especially if they have a chewy crust. Other breads need lower temps so the crust doesn't get too dark

The National Science Foundation marks its 75th anniversary this week.

Rather than celebrate, it's time to save it.

NSF REU sites awarded:
2015 - 207
2016 - 232
2017 - 248
2018 - 204
2019 - 209
2020 - 222
2021 - 189
2022 - 219
2023 - 212
2024 - 217
2025 - 52
This is not likely to increase; REU awards are made early in the year to enable recruitment for summer.

We are saddened by the recent loss of Fred Greene, professor emeritus and physical organic chemist. A member of our community for over 40 years, he was a beloved professor and mentor, celebrated for his lasting impact on generations of chemists.

The "brain drain" is not going to come from scientists moving abroad, but from scientists being forced into work that does not require their expertise so that they can pay their bills.

Agreed. However, not all non-faculty are admin. There are a lot of scientific staff running instrumentation facilities, doing research, etc. Those who aren't paid directly from grants or user fees are often supported by overhead.

The response of the science community to the last month is not about one statement or action. It's about all of us with our different frames. For Science's part, we are doing what we have always done and have no plans to change. My thoughts on what we can do. www.science.org/doi/10.1126/...

Let’s say that, conservatively, the 2.3 million federal employees spent an average of two hours dealing with, having meetings about, or just thinking about the OPM email. Captain Efficiency over there just cost the government 4.6 million person-hours for literally no reason.
