sorry but it's really funny that the same type of centrist pundit freaks who are like "mamdani won't make good on his campaign promises so DON'T vote for him!" were the same ones who said "trump won't make good on his campaign promises so it's fine if he wins"

From MRI to Ozempic: breakthroughs that show why fundamental research must be protected In these financially straitened times, funders must recognize that great discoveries often arise from work that was looking for something completely different.

The importance of basic research
โ€œno one wants to see taxpayersโ€™ monies being misspent. But world-changing discoveries often occur unexpectedly and are built on yearsโ€ฆdecades โ€” of fundamental research that expanded our knowledge of the worldโ€

Live cell ACTIN imaging has never been easier with SPY650-FastAct_X!

1. Add the probe to the cells
2. Image 1h later

SPY650 is highly suited for STED imaging. The image shows a confocal/STED comparison of the fine actin mesh in a live HeLa cell.

SynapseNet is a deep learning based software tool that automates the segmentation of vesicles, mitochondria, synaptic compartments, and the active zone. This is visualized in three panels. On the left, a section of an electron tomogram with a synaptic compartment densely filled with vesicles, which appear as round structures with dark boundary and light body in the image, is shwon. The top right panel shows the segmentation result of vesicles, visualized by masks with an individual color per vesicle and outlines for the segmented compartment (red) and active zone (blue). The bottom right panels shows a 3D rendering of the segmentation with vesicles shown as yellow spheres.
