Keep calm and be transparent: advice from scientists who retracted their papers Retractions correct the scientific record, but they have stigma attached to them. Some in the research community want that to change.

We're thrilled to announce the Ctrl-Z Award, a US$2,500 prize for researchers “who discover substantial errors in their published work and take meaningful steps to correct the scientific record."

When I graduated from high school my counselor (who was great) told me it was good I wanted to be a physicist because I'd never be a great writer. I was also the worst writer in my frosh expos course.

I am now an award-winning writer. BECAUSE I PRACTICED!!!!!!

GOP Congressman Says ‘Muslims Don’t Belong In American Society’ Rep. Andy Ogles of Tennessee also called it “a lie” that diverse groups of people can respectfully engage with each other.

Diverse groups of people have no trouble respectfully engaging with one another. I see it all the time. It's the best of humanity.

Small-minded assholish bigots, however, have trouble with respect for anyone, and don't deserve our respect or consideration. He's taking a very anti-Christian stand.

I know people are very sensitive about the use of the word “genocide” but the attempts to medically eliminate trans children is very clearly meets the standard because they are trying to eliminate a population and also they know some of those kids are going to kill themselves

Crude oil prices, showing a very sharp increase in the last day, from around 65 to 101 dollars per barrel..

Oil prices wouldn't be all over the news today if more of our economy was powered by local, secure renewable energy.

This isn't an "energy crisis". It's a fossil fuel crisis.

44% of UK electricity came from renewables in 2025. More of that plus an electrified economy => no more oil shocks.

the microfluidic channels

the microfluidic channels

Do you know those annoying layer lines you get with FDM 3D printers? Those layers you try to avoid or hide? 
What if I tell you we can use them to make 15-micrometer-tall microfluidic channels?

No profession embraces “alternative facts” like freaking realtors.

Me: points at massive structural water damage

Realtor: “All houses built before 2010 have that.”

Ah yes, the classic 1960s luxury feature: structural water damage!
