Detecting Delta Variant in 15 minutes! New medical device under spotlight - Sci-Tech - DotDotNews https://t.cn/A6IclP3X

A small device made by a Shanghai-based medical equipment producer could detect the Delta Variant of the coronavirus in 15 minutes.

XLEMENT, an incubatee of the Wuhan Institute of Optics and Electronics, shipped a batch of COVID-19 detectors to Morocco on Tuesday (Aug. 10), which can quickly and accurately identify the Delta variant within 15 minutes.

Reports pointed out that the specificity and sensitivity of the COVID-19 antigen detection kit are close to 100%, and can be used for rapid screening of asymptomatic patients infected with the coronavirus.

According to the person in charge of the company, the Delta Variant does not show significant changes in antigenic structure, so specific identification at the nucleic acid level is the key to differentiate the virus strain.

【太阳光球层中存在尚未被认知的小尺度磁冠拼接层】

中国科学院云南天文台研究团队提出了一种通过分析 p 模式震荡频率来探测太阳大气层中小尺度磁场分布的新方法，并且发现太阳光球层中存在一个以前尚未被认识到的小尺度磁冠拼接层。该研究成果 “Can small-scale magnetic fields be the major cause for the near-surface effect of the solar p-mode frequencies?” （小规模磁场能否成为太阳 p 模式频率的近地表效应的主要原因？）于近日在《天体物理杂志》上发表。
