NASA Aims to Fly First Quantum Sensor for Gravity Measurements This mission will pave the way for groundbreaking observations of everything from petroleum reserves to global supplies of fresh water.

I guess there is a funded mission to do something very close to this www.jpl.nasa.gov/news/nasa-ai...

β€œMeasure Fails” Budget Phasing Strategy
Phase 1 - In January 2027:
β€’ 63% train hours cut and 10 station closures (20% of stations)
β€’ 30% fare increase
β€’ Target $30M of (half-year) reductions in fleet/non-fleet maintenance, police, and system support
β€’ Balance remainder of FY27 with one-time resources and financial deferrals
β€’ Assess: ridership/revenue impacts; performance of system support; impacts/risks of asset closures; and
determine if Phase 2 can be safely implemented
Phase 2 - If feasible, in FY28 (July 2027 service change):
β€’ Cumulative 70% train hours cut, 15 station closures (30% of stations), and segment closures (32
miles or 25% of system length)
β€’ Cumulative 50% fare increase
β€’ Target over $130M of cumulative budget reductions in fleet/non-fleet maintenance, cleaning,
police, and system support
β€’ Defer remaining capital allocations
β€’ Based on observed conditions of closed system segments, study options and tradeoffs for
stopping train service
Phase 3 - When required:
β€’ If determined BART can’t safely or legally operate with available resources, stop passenger service
β€’ Use existing District tax revenues to secure system assets
β€’ Work to determine system’s future

BART's newly released concepts for what they'll do if Connect Bay Area transit funding measure fails are terrifying.

Phase 1: 63% train hours cut & 10 station closures
Phase 2: Cumulative 70% train hours cut, 15 station closures
Phase 3 (if required): END BART SERVICE

We must pass the measure!

A line plot with the numbers of NSF awards for fiscal years 2021-2026. The curve for fiscal year 2026 is quite a bit lower than those for 2021-2025 while the curve for fiscal year 2026 (in red) is much lower than all through the same date.

But, as they say, there is no time like the present

[OK, maybe the 1930s if you want to nitpick]

Are female economists treated differently than males in academic seminars?

These authors wanted to know whether gender shapes how scholars are treated when presenting research.

So they built a massive dataset of 2,000+ economics seminars, job talks, and conference presentations from 2019–2023...

We can verify our method with a simply logic: if we are really reconstructing the 3D dark matter field (Ξ΄) of the Universe, then the light from the Cosmic Microwave Background should be passing through this Ξ΄-field, imprinting a correlation between the two.

We find a 3-4Οƒ detection of this signal!

An immediate shutdown of DHS is better because passion and resolve is strongest now. That’s why Republicans wanted a 6-week CR. And it’s why we demanded only 2 weeks.

But working from a place of only DHS being on the line is maximum strength.

Crucial we make sure Ds do not shy away from the moment

this is a good response and the reason is that democrats look for any opportunity at all to back away from confrontation and it needs to be made clear that this doesn’t cut it in terms of consequences. i will be calling my representatives saying as much!

the amazing thing is that this shift is almost uniquely due to the actions of organizers, activists, and community members who have been documenting the human toll of immigration enforcement. Now just imagine if we had an opposition party that understood this and got behind the people.

Evening all,

Thank you to everyone who followed along with my coverage of this demonstration in Chicago today.

I love this work, but as an indie journo, for the moment, I'm pretty reliant on community support to do it.

Your support helps me to keep on reporting.

NYT video analysis confirms victim’s gun was removed before he was shot. So he was unarmed. https://www.nytimes.com/2026/01/24/us/minneapolis-shooting-federal-agents-video.html

Our initial analysis is up.

The video footage appears to show that the gun was taken away from the man before he was shot.

He was UNARMED before any of the shots were fired.

NB from the bottom of that page: "The age of the man who was shot has been corrected to 37, per information from the police chief. The AP previously reported his age as 51 based on a hospital record."
