Chinese discovery confirms Darwin's prediction on carnivorous plants_我的网站

一 |     (ECNS) -- Chinese scientists have identified a flowering plant species on the Qinghai-Xizang Plateau as a new lineage of carnivorous plants, providing evidence for Charles Darwin’s prediction more than 150 years ago.         A study published on Tuesday found that Saxifraga candelabrum, a flowering plant, can attract, capture and digest insects, while absorbing nitrogen from their bodies.    Researchers observed sticky glandular hairs trapping prey, detected digestive enzyme activity, and confirmed nutrient absorption using isotope-labeled fruit flies.    Led by Sun Hang’s team at the CAS Kunming Institute of Botany, with collaborators from Wuhan Botanical Garden, Jishou University and the University of Florida, the findings resolve a long-standing question over whether certain Saxifraga species possess true carnivorous traits.    In 1875, Darwin proposed that some species of Saxifraga might be carnivorous because they possess sticky glandular hairs capable of trapping insects. However, evidence supporting the hypothesis had remained unavailable until now.    (By Helen Mo, intern Liu Shuangjing)                    。1月10日，据外媒报道，在CES 2019上，金士顿正式发布了其A2000和KC2000系列NVMe固态硬盘，与上一代产品相比，每一个固态硬盘都有更高的性能。金士顿的新一代固态硬盘均采用64层3D TLC NAND，并已从群集控制更换为最新的硅运动芯片。

二 | A2000还使用PCIe 3.0 x4配置，允许NVMe SSD具有更多带宽以提高传输速度。

三 | 两款新的固态硬盘都将提供256 GB、512 GB和1024 GB型号，高端KC2000固态硬盘也将提供2048 GB版本。成本较低的A2000将提供2000/1500 MB/s的连续读/写速度，而KC2000将提供3000/2000 MB/s的连续读/写速度。这两款固态硬盘预计将于3月底或4月初上市。定价信息和其他规范将在稍后发布。
