Solving million-year problems requires more than just #AI- it needs transparency and solid #science.
Could this be the future of trustworthy technology?

Unsupervised image velocimetry for automated computation of river flow velocities Abstract. Accurate, long-term measurements of river flow are imperative for understanding and predicting a broad range of fluvial processes. Modern technological advances are enabling the development ...

Iโ€™m delighted to share that our latest research has just been published in HESS.

We developed an unsupervised workflow to estimate river surface velocities from videos. Testing on 11,000+ videos against 274 gauging measurements showed excellent agreement.

Since the Tลhoku quake and tsunami struck in 2011, Japan has built three offshore monitoring networks comprising more than 200 instrument stations, connected to the mainland by optical fiber. The networks provide real-time warnings and insights into subduction zones, where one tectonic plate dives under another at a seafloor trench.

In the next few months, Japan will finish work on an instrumented network of seafloor cables and wire it directly into a national early warning system.

Last Wednesday the Birchgletscher in the Swiss Alps collapsed, devastating large parts of the village #Blatten and blocking the Lonza river which created a small lake.

Thanks to aerial images shared by #swisstopo, I was able to create a 3D model of the area.

Trumpโ€™s NIH And NSF Cuts Estimated To Cost The U.S. Economy $10 Billion Annually Economists find public R&D drives U.S. productivity growth โ€” and pays for itself

Investing in basic science more than pays for itself! Cutting NSF and NIH would hurt the US economy. (Now might be a good time to remind your congressional reps about this)

A landscape shaped by active tectonics: the Taygetos range with the Sparta fault at its base and our @ipgp.bsky.social master and PhD students in front.
The Sparta fault made the 464BCE #earthquake of magnitude 7+, an event that has likely triggered the 3rd Messenian war.

This image cannot be shared enough. This is what our country would look like if we stop pumping water out of our polders. And in the meantime, we have closed all but one earth science departments, because itโ€™s a little but more expensive than the average study. What could possibly go wrong.

Scatterplot titled โ€œEmpirical Evidence of Ideological Targeting in Federal Layoffs: Agencies seen as liberal are significantly more likely to face DOGE layoffs.โ€
	โ€ข	The x-axis represents Perceived Ideological Leaning of federal agencies, ranging from -2 (Most Liberal) to +2 (Most Conservative), based on survey responses from over 1,500 federal executives.
	โ€ข	The y-axis shows Agency Size (Number of Staff) on a logarithmic scale from 1,000 to 1,000,000.

Each point represents a federal agency:
	โ€ข	Red dots indicate agencies that experienced DOGE layoffs.
	โ€ข	Gray dots indicate agencies with no layoffs.

Key Observations:
	โ€ข	Liberal-leaning agencies (left side of the plot) are disproportionately represented among red dots, indicating higher layoff rates.
	โ€ข	Notable targeted agencies include:
	โ€ข	HHS (Health & Human Services)
	โ€ข	EPA (Environmental Protection Agency)
	โ€ข	NIH (National Institutes of Health)
	โ€ข	CFPB (Consumer Financial Protection Bureau)
	โ€ข	Dept. of Education
	โ€ข	USAID (U.S. Agency for International Development)
	โ€ข	The National Nuclear Security Administration (DOE), despite its conservative leaning (+1 on the scale), is an exception among targeted agencies.
	โ€ข	A notable outlier: the Department of Veterans Affairs (moderately conservative) also faced layoffs despite its size.

Takeaway:

The figure visually demonstrates that DOGE layoffs disproportionately targeted liberal-leaning agencies, supporting claims of ideological bias. The pattern reveals that layoffs were not driven by agency size or budget alone but were strongly associated with perceived ideology.

The DOGE firings have nothing to do with โ€œefficiencyโ€ or โ€œcutting waste.โ€ Theyโ€™re a direct push to weaken federal agencies perceived as liberal. This was evident from the start, and now the data confirms it: targeted agencies overwhelmingly those seen as more left-leaning. ๐Ÿงตโฌ‡๏ธ
