Self-Aligned Multilayered Nitrogen Vacancy Diamond Nanoparticles for High Spatial Resolution Magnetometry of Microelectronic Currents Nitrogen vacancy diamond nanoparticles (NVNPs) are increasingly integrated with methods for optical detection of magnetic resonance (ODMR), providing new opportunities spanning the visualization of magnetic fields in microelectronic circuits, environmental sensing, and biology. However, only a small number of studies utilize aggregates of NVNPs for surface-wide magnetometry, with the fact that spin orientations in aggregate NVNPs are inherently misaligned, precluding proper magnetic field detection, compared with expensive monocrystalline diamonds. A post-processing method for layering NVNPs with aligned center orientations can potentially facilitate superior NV magnetometry by allowing sensitive detection with a simplified probe preparation. We present novel technology for creating densely stacked NVNP monolayers with inherent interlayer alignment for sensitive measurement of local field perturbations in microelectronic traces. We establish spatial characteristics of deposited aggregates and demonstrate their ability to capture dipoles from conducting microwires via ODMR. Our approach forms a novel accessible protocol that can be used for broad applications in micromagnetometry.

Advances in neural sensing arrive by fundamental technology development. Very excited to have my latest paper out today in Nano Letters pubs.acs.org/doi/full/10....

In the preprint, we discuss means for rapidly documenting partially finished projects, as well as publishing ‘as you go’ to prevent future problems in an uncertain environment.

We emphasize solutions that can be done quickly and on a limited budget.

Lawsuit aims to broadly overturn NIH’s grant terminations Multiple groups and NIH-funded scientists challenge agency’s decision as arbitrary and capricious

Top scientists warn that Trump policies are causing a 'climate of fear' in research Some 2,000 scientists, including dozens of Nobel Prize winners, have signed an open letter warning that the U.S. lead in science is being "decimated" by the Trump administration's cuts to research.

US health department announces major overhaul under health secretary Kennedy The U.S. Department of Health and Human Services said it will cut about 10,000 full-time jobs and close half of its regional offices.

0000 more HHS employees spanning FDA, NIH, CDC and Center for Medicaid Services to be let go by Friday. There is zero way this hasty and ill-considered continued hatchet job doesn't directly impact the healthcare for your family and hurt the economy.

In an 1997 AI class at UT Austin, a neural net playing "infinite-board" Tic-Tac-Toe found an unbeatable strategy:


Choose moves billions of squares away, causing your opponent's to run out of memory and crash, forfeiting their turn.


The winning move was to kill your enemy.

I honestly am having trouble believing it has come to this 🧪

Two days ago, Deepseek surprised everyone with an "undefined-behavior" PTX optimization speeding up particular ML workloads on a Hopper NVIDIA GPU Kernel.

Let's reverse engineer the hack, implement it ourselves, and benchmark the speedup on an H100.

Would recording all neurons reveal their interactions? For years, I was captivated by the idea that if we could record the activity of every neuron in the brain, we’d eventually crack the code…

If we could record all neurons we still would not know how they communicate: medium.com/@kording/628...

Thousands of probationary employees fired as Trump administration directs agencies to carry out widespread layoffs | CNN Politics The Trump administration broadened its effort to terminate thousands of probationary workers on Thursday, instructing agencies on a call to move forward with the layoffs.

Tens of thousands of government employees laid off tonight including at Veterans Affairs, National Institutes of Health and the CDC in what is already being dubbed the St. Valentine’s Day Massacre.

New from the Ludwig lab!

This is going to be a long battle. The point is ‘shock and awe’ to take away your motivation to fight this stupidity. Don’t give in.

If you are a leader in this field, or aspire to be one, now is the time to get VERY loud. You may not have another chance if you sit this one out.

The unannounced surprise NIH cut to 15% indirects is brilliant in its own way. I couldn't come up with a better way to cut only .05% of the federal budget that would cause immediate small business job losses in the high growth health and tech sector, while destroying U.S. leadership in science.

New NIH guidance immediately and retroactively changing indirect rates to 15%. The rationalization in this guidance pointing to accepting zero percent indirect costs for some non-profits grants may be one of the dumbest comparisons I’ve ever seen.
