End of pandemic in sight for Europe: WHO******

Two years after the outbreak of COVID-19, Europe could soon enter a "long period of tranquility" due to high vaccination rates, the milder Omicron variant and the end of winter, the WHO said Thursday.

WHO Europe director Hans Kluge said the respite was "a ceasefire that could bring us enduring peace."

"This context leaves us with the possibility for a long period of tranquility," he told reporters on Thursday.

Widespread immunity from vaccines and infections, combined with the change of season, also puts Europe in a better position to fend off any resurgence in transmission, he said.

"Even with a more virulent variant" than Omicron, Kluge said.

"It is possible to respond to new variants that will inevitably emerge – without reinstalling the kind of disruptive measures we needed before," Kluge said.

This was "not to say that (the pandemic) is now all over," but "there is a singular opportunity to take control of the transmission," he stressed.

He cautioned that the optimistic scenario would only hold true if countries continued their vaccination campaigns and intensified surveillance to detect new variants.

He also urged health authorities to protect risk groups and to promote individual responsibility, such as social distancing and mask-wearing.

'Knock-on effect'

With the more contagious Omicron variant in circulation, infections have surged across the WHO's European region, which comprises 53 countries, including some in central Asia.

Some 12 million new cases were registered last week in the region, according to the WHO, the highest level since the start of the pandemic.

But faced with a lower level of hospitalisations than in previous waves, several European countries, including France, Ireland and the United Kingdom, have announced the lifting or a considerable reduction of restrictions, despite record or very high cases.

Denmark on Tuesday became the first European Union country to lift its domestic COVID-19 restrictions, followed later in the day by Norway.

Speaking on the eve of World Cancer Day, Kluge also expressed concern over the "catastrophic impact" the pandemic has had on cancer care around the world.

In the last three months of 2021, cancer screenings and treatments were disrupted by five to 50 percent in all countries surveyed, he said.

"The situation has improved since the first quarter of last year," he said. "But the knock-on effect of this disruption will be felt for years."

He urged Europe's health-care authorities to take advantage of the expected seasonal COVID lull to reduce backlogs in chronic care services.

明明是春天,重庆街头却黄叶成堆如同秋天,你知道为什么吗?******

原标题:明明是春天,重庆街头却黄叶成堆如同秋天,你知道为什么吗?

今天是一年一度的谷雨,这是春天的最后一个节气,这时候太阳到达黄经30°,源自古人“雨生百谷”之说,这时候也是一年一度最适合播种移苗、埯瓜点豆的时候,然而明明是春天,但是重庆街头,我们看到的景象,却如同秋天一样。

谷雨时节,重庆真的飘起了小雨,中午的时候有短暂放晴,早上和下午都一直沥沥淅淅下过不停,也正是这样的降温的天气,让重庆街头,到处都可以看到大量的落叶,其中以黄桷树最为明显,为什么会这样呢?下午我们一起来聊聊这个话题。

黄桷树原名为黄葛树,是重庆的市树,由于在重庆方言中“角”与“葛”读音相同,加之重庆人认为树木名称应有“木”旁,像金属都有“金”旁,鱼类都有“鱼”旁,江河湖海都有三点水一样,所以重庆人一直都将黄葛树称为“黄桷树”。

作为市树,黄桷树不仅在重庆大街小巷随处可见,而且重庆市名有很多地方都以黄桷命名,比如黄桷坪、黄桷垭、黄桷峡、黄桷渡等,这种树的生命力极为顽强,很多都生长在石坎、石崖和城墙上,根系紧紧地扎在石头缝里,屹然而立。它属于“气生根”植物,只需少量的根系置入土壤就能生长,裸露的根须则可以直接从空气中吸收水分。

黄桷树属高大落叶乔木,其茎干粗壮,树形奇特,悬根露爪,蜿蜒交错,古态盎然。枝杈密集,大枝横伸,小枝斜出虬曲。不仅生命力强大,而且也很长寿,百年甚至几百年的古树在重庆都是很常见的,它们犹如一把把巨伞,为人们遮风挡雨。

至于黄桷树,为什么会在春天落叶?以前常有人解释说是什么季节栽种的,它便在什么时候落叶,其实这样的说活并没有科学依据,属于一种误传,黄葛树是介于落叶与常绿之间的冬青树种,树叶的寿命较长。按理应在深秋初冬的季节落叶却延长到第二年仲春初夏才开始掉落,并且一落叶,马上就长出嫩叶,甚至有些树是边落叶边发新芽。

另一方面,以更科学的解释是,像黄桷树这样的冬青物种,春天落叶延长了叶片的寿命,主要有两个好处,第一是叶片能够更长时间地进行光合作用,为植株在春天的生长提供更多能量,其二则是冬天没有脱落的老叶中的氮磷等养分可以被转运到春天的新生叶中,这样减少了因落叶造成的养分不足,有利于春天新叶的迅速生长。

也正因为如此,所以重庆这几天因为下雨降温而加速了这类冬青树种的落叶,才出现了这组图片中街头落叶成堆的现象,而且这样的现象并不是重庆所独有,南方很多城市都普遍存在这个问题,其中又以黄桷树、阔叶榕等树种为最。

对于这样的解释,你明白了吗?
