Uhhhh Iโ€™m not sure Iโ€™m ever going to be able to present again with a straight face after reading thisโ€ฆ.

The most unsatisfying part is that Haaland has to foul back to preserve the outcome. I donโ€™t love that but Iโ€™m not sure addressing that is worth ruling the goal out

Managed to get involved or impact the outcome in any way. Itโ€™s not that the fouls cancel out, itโ€™s just that they didnโ€™t impact the goal. Cherki is the one hard done by.

Wilsonโ€™s parade of horribles that he uses as reasons the call must be upheld is completely reversible. What if Man City loose the title on goal difference now? What if Liverpool donโ€™t make the CL as they lost at Sunderland? Two players fouled each other trying to get involved in a play. Neither

You may not like the Liverpool red card, but it was the right call | Jonathan Wilson Referee Craig Pawson sent off Dominik Szoboszlai by the letter of the law; the only way it should be done

Iโ€™m not sure I agree with any of Wilsonโ€™s logic. Cherki struck a goal-bound ball. There were multiple off the ball fouls by others, which didnโ€™t impact the outcome. Reds are for denying a team, not a specific player, a goal scoring opportunity (per the rules)

Search for survivors halted after Massachusetts fishing boat lost at sea One dead and six missing as body and life boat from Lily Jean found after its disappearance from Gloucester port

I started my career supporting this industry and our societal inability to reduce the risk faced by fishing crews is a decades long failure that brings only sadness and frustration, with seven more families now forever torn apartโ€ฆ

The "but what would be better" question is key - I see it missed in large engineering projects where people revisit past decisions, assuming the road not taken would have been pothole-free. Howe isn't perfect, but a cup, CL knockouts - it's working. The league is different than when Man City grew...

This line graph illustrates the percentage change in agency staff levels from the previous year for nine major U.S. federal scientific and health organizations between the fiscal years 2016 and 2025. The agencies tracked include the CDC, Department of Energy, EPA, FDA, NASA, NIH, NIST, NOAA, and NSF. For the majority of the timeline between 2016 and 2023, the agencies show relatively stable fluctuations, generally staying within a range of +5% to -5% change per year. However, there is a dramatic and uniform plummet starting in the 2024โ€“25 period. Every agency depicted shows a sharp downward trajectory, with staffing losses ranging from approximately -15% to over -25%. The Environmental Protection Agency (EPA) shows the most significant decline, dropping to roughly -26%, while the National Institute of Standards and Technology (NIST) shows the least severe but still substantial drop at approximately -15%.

This is the most astonishing graph of what the Trump regime has done to US science. They have destroyed the federal science workforce across the board. The negative impacts on Americans will be felt for generations, and the US might never be the same again.

This is pure, unabashed bigotry.

If a politician said this about any other faith, they would rightfully be run out of their party.

But this kind of despicable anti-Muslim rhetoric is so normalized that a sitting Senator uses it without consequence.

A stain on our Congress.

Us 2 months ago - our kids have never been to Newcastle, they're huge #NUFC fans, and we haven't been back in a decade. Let's go this summer!

Us today: Will US citizens be allowed into the UK by the summer - should we really spend money on tickets?

This is the stupidest timeline ever.

Russia fucks up and Sweden joins NATO and their first NATO operation is a show of force in Greenland to protect it from the United States. That's a hell of a plot twist.

Would be interesting to know if there is any uptick in injuries for the 20 minutes after these long pauses. I get the desire to get each call correct, but there is also a balance with the costs

At the end of 2024, I expected 2025 to be a year when much of the zero-carbon fuel uncertainty would be resolved for the maritime domain, and work would start on scaling up solutions (probably multiple fuels). I significantly underestimated the Trump administration's power to slow decarbonization..
