To create high-resolution, 3D images of tissues such as the brain, researchers often use two-photon microscopy, which involves aiming a high-intensity laser at the specimen to induce fluorescence exci...
Microscopists have long sought a way to produce high-quality, deep-tissue imaging of living subjects in a timely fashion. To date, they have had to choose between image quality or speed when looking i...
The concrete world that surrounds us owes its shape and durability to chemical reactions that start when ordinary Portland cement is mixed with water. Now, MIT scientists have demonstrated a way to wa...
An international team of scholars has read an unopened letter from early modern Europe — without breaking its seal or damaging it in any way — using an automated computational flattening algorithm. Th...
美欧科学家研究发明隐藏物体透视成像新技术
美欧 科学家 隐藏物体 透视成像新技术
2019/8/28
来自威斯康星大学麦迪逊分校和西班牙萨拉戈萨大学的科学家借鉴经典光学经验，证明可以使用预测的“隐藏场景”来对障碍物进行成像。该技术在2019年8月5日的《自然》杂志的一份报告中有所描述。一旦经完善便可以广泛应用，从防御、救灾到制造、医学成像。这项工作主要由军方通过美国国防部的高级研究计划局（DARPA）和美国国家航空航天局提供资金，美国宇航局将这项技术视为在月球和火星上探测隐藏洞穴的潜在方式。
New research provides scientists looking at single molecules or into deep space a more accurate way to analyze imaging data captured by microscopes, telescopes and other devices.The improved method fo...
A new Rice University technique grabs images of chemical processes that happen faster than most laboratory cameras are able to capture them.The technique, super temporal resolution microscopy (STReM),...
