奥巴马迎白宫圣诞节

奥巴马迎最后"白宫圣诞节"
Obamas Prepare for Their Final White House Christmas
This is What's Trending Today...
President Barack Obama and his family will celebrate their eighth and final Christmas in the White House next month.
On Tuesday, White House staff and first lady Michelle Obama revealed this year's holiday decorations.
They include nearly 70,000 ornaments, 63 Christmas trees, 56 gingerbread houses, and two very large statues of the Obama family's dogs, Sunny and Bo.
An estimated 68,000 people will visit the White House during the holiday season. There is no cost to enter.
But, the very first people to see this year's decorations were military members and their families. Michelle Obama welcomed them to the White House Tuesday.
The first lady said the gold ornaments on the official White House Christmas tree honor military heroes. The Christmas tree is almost six meters tall and stands in the Blue Room.
This year's theme is "The Gift of the Holidays." Many of the decorations represent important gifts in America, including the "gift of a great education," Michelle Obama said.
In the White House Library, another Christmas tree is decorated with ornaments that honor girls. The word "Girls" is printed in a different language on each ornament.
A program called Let Girls Learn has been a major effort of Michelle Obama's. It aims to help girls and young women around the world get a quality education.
Another "gift" is the gift of good health. A tree in the White House Green Room is hung with fruit grown in the White House Garden. Healthful eating and exercise have also been important issues during Obama's eight years as first lady.
Most of the ornaments and other decorations were reused, the White House said. Just 10 percent were new.
More than 90 volunteers worked on the decorations. On Tuesday, the first lady thanked the volunteer decorators.
"We can't wait to start welcoming people into their White House this holiday season. To everyone who created these stunning displays.... I want to once again say thank you. You all did a phenomenal job of turning this house into a magical place."

Mother trees colonize their kin with bigger mycorrhizal networks.

Forests aren't simply collections of trees,
森林不是简简单单的树的“集合”，
they're complex systems with hubs and networks that overlap and connect trees and allow them to communicate,
森林是拥有枢纽和网络的复杂系统，它可以承载树木并且把树连接起来，使得它们可以互相沟通，
and they provide avenues for feedbacks and adaptation, and this makes the forest resilient.
它给树木提供了互相反馈的渠道和适应的方式，也使得森林的恢复力变得更强。

That's because there are many hub trees and many overlapping networks.
这是因为在森林中存在着许多的中心树和重重叠叠的网络。

But they're also vulnerable, vulnerable not only to natural disturbances
但森林也还是很脆弱的，之所以脆弱不仅仅是因为它们会受到自然界的干扰，
like bark beetles that preferentially attack big old trees but high-grade logging and clear-cut logging.
比如树皮甲虫会时不时地攻击粗壮的老树，而是因为高强度伐木和皆伐的影响。

A new report on the Internet and how we use it says that more of us are using social media. The Pew Research Centre's Internet and American Life Project surveyed 2,277 U.S. adults about their Internet use. About two-thirds of Internet users now belong to social networking sites. Pew reports that ninety-three per cent of social network users have joined Facebook, up from 73 per cent in 2009. The continued rise in Facebook’s popularity contrasts with the decline of MySpace. Twenty-three per cent of those questioned said they had a MySpace profile, down from 48 per cent in 2009. Twitter continues to attract more users, with 11 per cent of respondents saying they use it, up from 6 per cent in 2009.

The report showed big differences between how men and women use social media and how we manage our privacy. Women are more likely than men to delete friends. Sixty-seven per cent of women said they have deleted friends compared with 58 per cent of men. The study reported that men are almost twice as likely as women to have posted messages, photos or videos that they later regret. Fifteen per cent of men said they have done this, compared with eight per cent of women. The study also showed women to be more cautious who they share information with. Two-thirds of women use the highest privacy settings, sharing data only with friends. Less than half of the
men did so.
