D614G reshapes allosteric networks and opening mechanisms of SARS-CoV-2 spikes
The SARS-CoV-2 spike glycoprotein binds human epithelial cells and enables infection through a key conformational transition that exposes its receptor binding domain (RBD). Experimental evidence indic...

Nevertheless, we persisted ❤️
📣 NEW BIORXIV ALERT!! 🚨
Using WE MD, linguistic pathway clustering, dynamical network analyses, and HDXMS we reveal a hidden allosteric network within the SARS2 spike S1 domain and predict how the D614G mutation impacts this network!

Academia is a really racist and sexist place. Larry Summers, as the president of Harvard, epitomized that racism and sexism but he is not unique. That's why we needed DEI.

lets all be whistle blowers
“Short bursts indicate an ICE sighting. Long whistles indicate agents making arrests. If you hear the whistle and you’re undocumented, said [Whitney Hu, a community activist and organizer with South Brooklyn Mutual Aid], ‘you hide. And if you’re somebody who’s not, you go to the street.’”
As ICE Street Raids Ramp Up, New Yorkers Stock Up On Whistles
Taking a cue from Chicago, community groups have distributed thousands of whistles in recent weeks — a grassroots system people in other cities have adopted to help neighbors sound the alarm.

What strikes me about the Summers-Epstein emails?
Young women in science often walk away from exchanges thinking "did he mean it like that? he probably is just from a different time"
anddd nope. they know what they are saying, why they are saying it, and they are achieving their intended impact.

I can reassure the New York Times that networks of mutual protection, and misogynist retaliation efforts that benefit abusive men at the expense of the young women they prey upon, are very much still intact post-Me Too.
This is nauseating: “As the emails stretch through the years, they show how that protected realm vanished into the mists of time, pulled under by the rising forces of the internet and the #MeToo movement.” A “Gone With the Wind” framing for sexual abuse and harassment.
Seriously, what is wrong with these people?

I wanted to share probably the most important sermon I’ve given and it’s while I’m being arrested. It’s torture pure and simple what happens at #Broadview. I’m ok, though I was thrown to the ground and choked with my pectoral cross. A review of the video shows I was peaceful - did I deserve this?

I really need to get to bed, but I just poked my head out the back door again. This is the view from my deck. All of this is looking south. When the geomagnetic storms are like this, the oval overshoots me and stretches into the US, which is why so many are seeing it tonight. #aurora

Pre-ACA, I was a postdoc on an NSF fellowship at a university that didn't offer employment benefits to independent fellows. At that time, being a woman meant that my premiums were double that of my male counterparts. The extra cost came out of my grant's budget for benefits, equipment, and travel.
