I've been training OCR models for 2 years. The progress we've made in handwriting is astonishing - from barely readable to almost perfect transcription.

Ah yes, the (many) circle(s) of life! Can you guess what this video is showing *without* clicking on the caption?

Liftoff of Starship's first orbital flight

[Black Hole @konstructivizm]

Four years ago tonight, we punched a moon.

On 26 September 2022, NASA’s DART spacecraft found Dimorphos — a rubble pile the size of a stadium, orbiting the larger asteroid Didymos — and hit it at 6.1 kilometers per second. The last frames were boulders swelling to fill the camera, then static. That was the point. Not a crater for its own sake. A shove.

It worked louder than the test required. Dimorphos’s orbit around Didymos shrank by about 33 minutes, dozens of times the success threshold. The impact did not merely dent a rock. It threw a plume of debris that acted like a second engine: recoil from the ejected rubble did most of the steering. Humanity had, for the first time, measurably rearranged a body in the solar system on purpose.

The crime scene is about to get its inspector. ESA’s Hera, launched in October 2024, is weeks from the Didymos pair — rendezvous planned for November 2026. It will weigh the moonlet, map whatever is left of the impact site, and turn that 33-minute shove into calibrated physics: how much mass flew off, how the shape changed, what a kinetic impactor would do to the next rock that actually aims at Earth.

DART was the punch. Hera is the autopsy. Together they are the first full rehearsal of planetary defense.

Let's get the week started with some knowledge: capillaries act as the ultimate interface between arteries and veins, delivering vital oxygen and nutrients directly to tissues while removing metabolic waste products.

EYE can't believe there are only two more days until we reveal this year's #SmallWorldInMotion winners! What are you excited to see among this year's winners?

I'm particularly excited by Atlas's ability to reconstruct scenes from a very small number of input image -- was able to create this flythrough of London's Natural History Museum by combining 3 input images I found from completely separate sources on Google Images

New analysis reveals that the flood wave traveled the first 25 km (15 miles) of its catastrophic descent at an average speed of 150 km/h (93 mph), reaching a maximum velocity of 190 km/h (120 mph) at the Nepal–Tibet border.

ONNX-compatible LightGlue: Local Feature Matching at Light Speed. Supports TensorRT, OpenVINO
https://t.co/Q1vDiknqVP
Open Neural Network Exchange (ONNX) compatible implementation of LightGlue: Local Feature Matching at Light Speed. The ONNX model format allows for interoperability across different platforms with support for multiple execution providers, and removes Python-specific dependencies such as PyTorch. Supports TensorRT and OpenVINO.

Today we are releasing the code for Gabor Fields https://t.co/I9OgajCSrv. A new way to understand volume rendering with primitives (think Gaussians, but different!), that allows us to do principled LOD, extreme acceleration (\w control variate theory) and much more #SIGGRAPH26

fire a ray for every pixel and check where it intersect with your function:

"12 strands are anchored on the outside to a fixed frame, and on the inside to a spinning dodecahedron. Although the dodecahedron spins continuously in one direction, the strands never become tangled. The strands return to their original configuration when the dodecahedron has rotated 720 degrees." - Jason Hise, https://t.co/FTNqlcBqP0
