Proud of @faezehjame.bsky.social and our latest paper on upregulation by #miRNA. miRNA upregulate protein expression of CD98hc, ST3GAL1 and ST3GAL2 in a coordinated manner. Regulation is bidirectional, changing the picture on how these #RNA work. #glycotime

Screening the human miRNA interactome reveals coordinated up-regulation in melanoma, adding bidirectional regulation to miRNA networks

Analysis of ST3GAL1/2 and CD98hc regulation by miRNA reveals co–up-regulation, adding a bidirectional twist to miRNA networks.

I put this to the test with Copilot and yeah, I think it's fair to say that it struggled with the structure of caffeine

A Co-pilot created drawing of a molecule that is definitely not caffeine

my latest investigation for @consumerreports.org is based on months of reporting and 60+ lab tests of leading protein supplements

we found that most protein powders and shakes have more lead in one serving than our experts say is safe to have in a day (🧵)

Oversized lab coats held in place with elastic bands, Frankenstein creations made by stitching two lab coats together or leaving the lab altogether. These have been the options for pregnant women in the lab. @geniuslabgear.bsky.social now wants to change this with the launch of a maternity lab coat.

There needs to be more coverage of this in the news. I have read so many stories bout this on Facebook, first hand stories of the terror of that storm, and very little coverage n media.

Screenshot of a Facebook post. Photo is an elderly woman holding a child on her ap on a couch with flood water around them. Both are wearing jackets inside. Text says: This was after our 1st drift.. staying put for awhile. Our 3rd and final drift was terrifying. House moving fast then we started spinning in circles. While we were spinning in circles my oldest daughter was just staring at me while I held onto my younger two. Kipnuk doesn't look like kipnuk anymore, like more than 3/4 of the homes displaced, power poles fallen. It smells like stove oil outside. Contaminated

Happy birthday to Millie Dresselhaus (née Spiewak; 1930-2017). She was a professor of physics & electrical engineering at MIT, known as the Queen of Carbon Science. 🧪🐡👩🏼‍🔬🎢

In my #linocut I've shown her in front of a carbon nanotube. She was recognized for her work on graphite, graphite intercalation🧵

‘Economics Nobel prize won by researchers who showed how science boosts growth’ by @philipcball.bsky.social in @nature.com www.nature.com/articles/d41...

Screenshot that reads:

The award "underlies the importance in investing in science for innovation and long-term economic growth", says economist Diane Coyle of the University of Cambridge. "It's great to see the Nobel prize recognize the importance of this topic," adds innovation policy researcher Richard Jones of the University of Manchester, UK. "It's important that economists understand the conditions that lead to technological progress," he adds. The winners, says Coyle, "have long been on people's list of potential candidates".

My quote of the day

Nancy Hopkins et al., A Study on the Status of Women Faculty in Science at MIT (1999)

They found that discrimination consists of a pattern of powerful but unrecognized assumptions and attitudes that work systematically against women faculty even in the light of obvious good will. Like many discoveries, at first it is startling and unexpected. Once you "get it", it seems almost obvious.

The editors of the CDC’s Morbidity and Mortality Weekly Report (MMWR) were apparently fired today.

The precursor to MMWR began in 1878 to address emerging public health threats rapidly.

We are not “great” without it. We are vulnerable to threats from sporadic foodborne illness to bioterrorism.

When we hear about a lone scientist who made groundbreaking discoveries on their own, it’s usually erasing the truth that science is a team sport, and field research builds on the local knowledge and expertise of the people that live there (8/10)

I love this poem. It was the last poem from Carver's last book written while he was dying of cancer. It is the inscription on his tombstone apparently too.

Thank you for writing this. I have been saddened but not shocked over the capitulation over EDI, which at its core is about opening opportunity to allow diverse meritorious candidates. The data is there showing that different perspectives are crucial in science and is sadly ignored.
