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

A | (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)
。三星电子(Samsung Electronics)周二在拉斯维加斯举行的国际消费电子展(CES)闭门会议上向客户展示了一款可折叠手机的原型。三星的一位客户高管表示,三星仍在改进可折叠手机硬件和软件的优化过程。”当它展开时,三星的可折叠手机将不会显示出任何折叠的迹象,”这位高管说,并注意到该设备的屏幕非常光滑。但是,完全折叠可能会损坏手机。因此,三星正在进行测试,以在手机折叠时略微倾斜边缘。当折叠时,三星的原型机会留下了一个折痕,但这个问题将在最终版本的机器中得到解决。据三星高管称,这款原型可折叠手机的屏幕在完全部署后显得更薄。

B | 折叠时,手机比感觉更牢固。三星没有向普通的消费电子产品展(CES)参观者展示其可折叠手机和其他近商业产品,而是只向参观其消费电子产品展区的私人客户展示。

C | 据一位技术行业人士透露,配备最新柔性屏幕和电池技术的三星折叠式手机可能至少以150万韩元(合1336美元)的价格售出。因此,三星可能将目标锁定在40多岁的购买力男性身上。三星计划今年上半年销售可折叠手机,仅生产约100万部,远低于其旗舰Galaxy S手机1000万部的生产目标。
