SpaceX seeks FCC nod to build data center constellation in space‎

SpaceX is requesting permission to launch as many as 1 million satellites into the Earth's orbit in order to pull off Elon Musk's latest grand vision of putting data centers in space to do complex computing for artificial intelligence. In a filing with the Federal Communications Commission made on Jan. 30, SpaceX said it's creating the solar-powered network in order to "accommodate the explosive growth of data demands driven by AI."

Using generative AI to help scientists synthesize complex materials‎

Generative AI models have been used to create enormous libraries of theoretical materials that could help solve all kinds of problems. Now, scientists just have to figure out how to make them. In many cases, materials synthesis is not as simple as following a recipe in the kitchen. Factors like the temperature and length of processing can yield huge changes in a material's properties that make or break its performance. That has limited researchers' ability to test millions of promising model-generated materials.

Iguanas fall from trees in Florida as icy weather bites southern US‎

Iguanas stunned by cold temperatures dropped from trees in usually balmy Florida on Sunday as icy conditions blasted southern U.S. states, dumping nearly a half-meter of snow in some areas and whipping up high winds that caused traffic chaos.

Japan says rare earth found in sediment retrieved on deep-sea mission‎

Sediment containing rare earth was retrieved from ocean depths of 6,000 meters (about 20,000 feet) on a Japanese test mission, the government said Monday, as it seeks to curb dependence on China for the valuable minerals.

Tiny new dinosaur Foskeia pelendonum fills in an evolutionary gap‎

An international team has described Foskeia pelendonum, a tiny Early Cretaceous ornithopod from Vegagete (Burgos, Spain), measuring barely half a meter long. Led by Paul-Emile Dieudonné (National University of Río Negro, Argentina), the study reveals an unexpectedly derived skull and positions Foskeia near the origin of the European herbivorous lineage Rhabdodontidae. The study is published in Papers in Palaeontology.

Single-cell microdevice isolates and profiles extracellular vesicles over weeks‎

Extracellular vesicles and particles are central to how cells communicate, especially in cancer, where they help shape metastasis and treatment resistance. However, most existing methods analyze vesicles in bulk, masking differences between individual cells. Some single-vesicle techniques offer particle-level detail but lose information about the cell that produced them. Other single-cell platforms face practical limits, such as short culture times or signal mixing between cells. These limitations make it difficult to study how individual cells behave over time. Based on these challenges, there is a clear need for technologies that can culture single cells long-term while isolating and analyzing the vesicles each cell produces.
