MIT tech powered the Artemis II livestreams
During the original US missions to the moon in the 1960s and ’70s, astronauts relied on radio-frequency systems to communicate, sending grainy, low-quality images and videos to Earth. But on the Artemis II Orion mission in April, spacecraft transmitted crystal-clear footage at speeds on par with th...

The next big thing in hydrogen could be undergroun
There’s a hunt for new sources of hydrogen, and the gas (or at least the right conditions to make it) could be hiding beneath our feet. Hydrogen can be used as a fuel in everything from large trucks to planes to steelmaking. It’s often hailed as a climate solution because when burned, it produces...
The role of the astronaut is in flux
When the four astronauts on board NASA’s Artemis II swung around the moon earlier this year, they set a new record for the farthest humans have ever ventured from Earth, surpassing the distance set by Apollo 13 in 1972 by some 4,000 miles. While no space mission can live up to the historic touch...

潜空间赋能机器学习：三大角色全解析
在人工智能领域，潜在空间（Latent Space）是一个由算法构建的抽象数学空间，用于压缩和表示复杂数据。它承担三种核心职能：描述性角色，为数据绘制语义地图；生成性角色，作为数据创造工坊；预测性角色，充当未来推演沙盘。这些角色在前沿研究中深度融合，支撑了如DALL-E、Gemini等AI模型的能力。尽管前景广阔，潜在空间仍面临语义清晰度、安全性和多模态扩展等挑战。随着研究的深入，它正成为提升AI性能、可解释性和可控性的关键。
这位科学家正在绘制儿童细胞的缺失图谱
