China's Xi rides high hopes ahead of presidency

(AP) ? China's fawning state media, jaded social media commentators and even poor corn and cabbage farmers agree: new Communist Party chief Xi Jinping is off to a good start.

"General Secretary Xi doesn't put on any airs. He talks like an ordinary person," said 69-year-old farmer Tang Rongbin. The new leader visited Tang's sparse, dimly lit farmhouse in Luotuowan village in December, bearing gifts of cooking oil, flour and a blanket.

Xi has styled himself as an economic reformer, an iron-fisted graft-buster, a staunch nationalist and a no-frills man-of-the-people ? spurring expectations for change. But as he prepares to be appointed to the largely ceremonial role of president, pressure will be growing on him to deliver.

China faces rising public anger over endemic corruption, a burgeoning rich-poor gap and the degradation of the country's air, soil and waterways. Slower economic growth and territorial disputes, especially with Japan, add to the tension.

Mounting protests over environmental issues, land seizures and high-handed officialdom point to the underlying social discontent. Days before the party conclave that brought Xi to power last year, thousands of protesters in the eastern city of Ningbo faced off against riot police outside government offices, calling on officials to halt a chemical plant expansion.

"I think there has been a revolution of rising expectations," said Willy Lam, an expert on party politics at the Chinese University of Hong Kong. "People realize they can get away with even demonstrations to make their wills heard."

Joining the clamor for change this past week were dozens of prominent intellectuals who signed a petition urging the government to ratify an international treaty on protecting human rights and the rule of law. Also, a group of about 100 parents of gays and lesbians urged lawmakers to legalize gay marriage.

The annual session of the national legislature, which opens Tuesday, will complete the once-a-decade handover of power that began in November when Xi and his leadership team assumed the top positions in the Communist Party. At the end of the session, Xi will take the title of president from his predecessor as party leader, Hu Jintao.

Deputies to the National People's Congress will rubber-stamp appointments of senior officials to the State Council, or Cabinet, to run economic and foreign policies; Xi and other party leaders finalized the personnel changes at a closed-door meeting last week. The No. 2 party leader, Li Keqiang, will become premier, the country's top economic official.

The legislature gives the Xi administration a high-profile platform to lay out policies to build the prosperous, strong and fairer society he has talked about in his public appearances.

Xi came to power in the wake of a scandal that exposed infighting and corruption in the highest reaches of the party. Exuding a confidence and ease lacking in the remote, wooden Hu, Xi has seized on the public's disgust over graft and its hopes for national greatness to rally support for his leadership.

"He certainly took challenges and made them opportunities," said Cheng Li, an expert on Chinese politics at the Brookings Institution in Washington. "He turned them around into great expectations for him, and great hope."

Xi visited an early testing ground for the market reforms that have transformed China into the world's No. 2 economy to align himself with reform in broad terms, though he has given no indication of the changes he wants to make.

He stopped off at Luotuowan and other farming villages to show his concern for those struggling to get by. And he has played to nationalist sentiments, taking a hard line against Japan in a long-festering territorial dispute, and touring military units to show his commitment to national defense.

Xi has disappointed some who had hoped for greater political freedom. Though he has espoused the virtues of constitutional government and the rule of law, dissidents continue to be harassed, and a crackdown on self-immolation protests in Tibetan areas has only intensified.

It is fighting graft that Xi has made the signature campaign of his first three months ? a popular campaign that so far featured more symbolism than action.

He launched a drive to cut out red carpets, motorcades and other official extravagance. State media touted that he preferred simple meals over the usual banquets leaders are given while on inspection tours. He has vowed to target corruption at high and low levels of power ? both the "tigers" and the "flies."

So far, it's mostly flies that have been swatted. A slew of lower-level officials have been punished after revelations they were keeping mistresses or amassing multiple unaccounted-for properties. Its highest-level victim has been a deputy provincial party chief suspected of influence peddling and dodgy real estate deals.

Many politically minded Chinese aren't convinced that Xi will take the painful steps needed to root out deeply embedded corruption. Eliminating graft would require an overhaul of the patronage-based political culture and restraining the party's unchecked power.

"Will it be like the past when there was great determination expressed in speech, but ultimately no effective efforts followed to control corruption?" said Ren Jianming, an anti-corruption expert at prestigious Tsinghua University in Beijing. "We haven't seen much in terms of specific measures."

Some Chinese want the party to allow its anti-corruption watchdogs to operate independently, and to require officials to declare assets publicly. A system in place since 2010 requires some officials to report income, real estate holdings and other wealth to their superiors ? not the public ? but that has done little to stanch graft. A few areas in Guangdong have recently been named as testing grounds for public asset declaration.

Still, resistance to full disclosure is high within the bureaucracy and perhaps even the leadership. Bloomberg News reported in June last year that Xi's extended family has amassed assets totaling $376 million, though it said none was traced to Xi himself.

"I believe that Xi should take the lead," said Wang Yukai, an anti-corruption expert at the Chinese Academy of Governance, which trains provincial and ministerial-level civil servants. "Politburo Standing Committee members also need to declare information about their spouses and children. This will pave the way for future declarations."

Many experts advocated an asset declaration mechanism when they attended a meeting called by Wang Qishan, the party's new anti-corruption agency chief, in late November, according to Ren, who was one of the participants. Ren said Wang noted that more research needed to be done but otherwise stayed noncommittal.

"There's now a lot of public expectation about anti-corruption work, and as the leading cadre in charge of this work, he must remain calm and rational," Ren observed. "It's easy to raise public expectations, but if you're unable to meet them, then you'll end up disappointing everyone."

Video: Expert on sequester: ?Cuts are not world-ending?



>> likes the cuts. everybody says they didn't want them. but i don't think we can say there was much of an effort to stop them. there is one 11th hour meeting. you've been there. behind closed doors , what happens? was this anything more than political theeter?

>> i do think they spent more time discussing how to deal with the next deadline which is at the end of this month and basically the funding mechanism for government throughout the rest of the fiscal year goes into effect. i think by the time leaders came to the white house yesterday the dye had been cast for several weeks. this is more about how to operate our fiscal situation going forward.

>> there's been a lot of talk about the president trying to get the message out there that he needs a little public outrage to carry this down the path he would like to see. yet, we see him changing the message saying this isn't going to be as dire immediately. how important is that message change to what he's trying to ultimately accomplish and will it work?

>> well, i think what you heard him say there is the cuts are arbitrary. they're dumb. and they will hurt the economy. i do think -- i mean apocalyptic is world ending. i don't think the cuts are world ending. i do think as they are phased in over a matter of weeks that you'll see the pain ratchet up, anything from threatening military readiness to making as much more inconvenient to travel by air, as kristen talked about, federal workers being furloughed. there's no doubt this will have an economic impact and that will be felt around the country.

>> it will be felt. do you think it will bring with it enough of that public outrage or are these cuts, in fact, here to stay?

>> well, i -- i'm going to answer yes to both of those questions. obviously the white house and democrats are betting on ramped up pressures as these cuts are phased in to bring republicans back to the bargaining table. i have to say, i think if you were betting today, it is far more likely that these cuts continue and are -- continue throughout this fiscal year than they are dialed back at this point. i think these cuts were implemented last night are here to stay for quite some time.

>> robert gibbs , nice to see you this morning. thank you.

'American Idol' Really Wants a Girl to Win this Season

"It's absolutely a girl's year to win," American Idol judge Keith Urban said in a conference call with reporters last Wednesday. But now that he and his fellow judges have picked the 10 guys and 10 girls that fans will vote upon, it almost seems like they're pushing viewers in that direction. The show hasn't exactly handed us a compelling group of guys here.

Cloud-Borne Bacteria May Affect Human Health and the Environment

Cover Image: March 2013 Scientific American MagazineSee Inside

Beyond affecting health, atmospheric microbes might also have an important effect on cloud formations and climate

Louis Pasteur opened a glass flask on Montanvert Glacier in the French Alps in 1860 and collected some air. A few days later the bottom of that flask was teeming with goo?proof to Pasteur and his colleagues that there was something in the air, something invisible but quite real. Today we understand what that invisible stuff is?microbes aloft in our atmosphere?but despite the more than 150 years that have passed since Pasteur's experiment, scientists are just beginning to understand how microorganisms in the air affect life on earth.

Recently scientists captured more than 2,100 species of microbes traversing the Pacific Ocean from Asia to North America on huge plumes of air in the upper troposphere?up to 12 miles above the surface of the earth. A good fraction of them were bacteria, which can mean trouble for human health. In Africa, in a region known as the meningitis belt, dust storms carry the bacterium Neisseria meningitidis (pictured above), which infects around 200,000 people there annually. Yet for most people in most places, the microbes in the air are totally harmless, says David Smith, a microbiologist at the nasa Kennedy Space Center and lead author on the work that found the 2,100 traveling microbes. ?You don't need to be worried,? says Smith, whose findings were published online last December in the journal Applied and Environmental Microbiology. ?This has been happening naturally, always.?

Beyond health, microbes in the atmosphere might also be important for climate. ?We're interested in whether they can contribute appreciably to the concentrations of cloud nuclei,? says Susannah Burrows, an atmospheric scientist at Pacific Northwest National Laboratory in Richland, Wash. Bacteria can clump together, forming the seed around which clouds form and thus providing a key component of our atmosphere, she notes.

Other researchers wonder exactly how microbes behave while aloft and if they can reproduce as they travel. ?We have several indications that microbes in the air are alive and active? and not just hitching a ride, says Paraskevi Polymenakou, an atmospheric microbiologist at the Hellenic Center for Marine Research in Greece.

For Dale Griffin, a microbiologist at the U.S. Geological Survey, the questions push beyond the atmosphere. ?No matter how high we look, we seem to be able to find life,? he says. Smith wonders not just how high that life goes but how it survives at such heights. ?As a student in biology, I felt like everything had already been investigated,? he says. ?The atmosphere allows the opportunity to characterize a place where nobody has looked for life.

Historic datasets reveal effects of climate change and habitat loss on plant-pollinator networks

Feb. 28, 2013 ? Are plant-pollinator networks holding together as the insects and plants in the network are jostled by climate change and habitat loss?

The question is difficult to answer because there is no baseline: few historic datasets record when plants first bloomed or insects first appeared and almost none follow both plants and insects.

Which is why biologist Tiffany Knight and her then postdoctoral research associate Laura Burkle were delighted to discover meticulous data on a plant-pollinator network recorded by Illinois naturalist Charles Robertson between 1887 and 1916.

Re-collecting 26 spring-blooming flowers from Robertson's network, Knight, PhD, professor of biology at Washington University, and Burkle, PhD, now assistant professor of ecology at Montana State University, discovered that the network had weakened.

Half the bee species associated with these flowers in Robertson's lifetime had disappeared, some pollinators were active before their plants had bloomed, plants weren't visited as often, and the bees that did visit weren't carrying as much usable pollen.

"The network is still there and still functioning, despite major perturbations," Knight said. "The bees still have food, plants are still getting pollinator service. But the service has declined, the network's structure is weaker, and its response to future perturbations much less certain," she said.

The study, the first to look at human disruption of plant-pollinator networks through the lens of historical data, appears in the Feb. 28th online edition of Science.

Robertson's astonishing legacy

A professor of biology and Greek at Blackburn College in Carlinville, Illinois, Charles Robertson collected flower-visiting insects near Carlinville between 1887 and 1916.

Over 20 years Robertson recorded visits from 1429 pollinators (including flies, beetles and butterflies as well as bees) to 456 plant species. He identified and described several hundred insects previously unknown to science. So respected is he among entomologists that roughly 20 additional species have been named for him. Robertson's meticulous database is probably the oldest of its type for flower-visiting insects.

"Before Robertson," said co-author John Marlin, PhD, a research affiliate at the University of Illinois's Prairie Research Institute who had re-collected part of Robertson's network in the 1970s, "almost all insect collecting was done independently of the plant. Robertson was one of the first to record the insect, the plant it was collected on, to the extent possible what the insect was doing, and other factors, which led to an explosion of information on insect-plant relationships."

Burkle said she particularly enjoyed the sleuthing needed to figure out Robertson's methods so that they could replicate them. "It was like solving a mystery, she said, trying to deduce what he had done from old ledgers, specimen i.d. tags, and his privately published book Flowers and Insects."

How Robertson's network is doing

"Robertson studied it all," Knight said. "He studied forests, he studied prairies, he studied roadside plants, he studied old fields; he even moved some plants to his own yard so he could study them more easily. If it was a species of flowering plant within a 10-mile radius of Carlinville, it was in his study. "

"To keep our project manageable," Knight said, we re-collected a subset of the network Robertson collected, focusing on one plant community: forest spring ephemeral plants. We looked at 26 plant species in this community, which were associated with 109 bees in Robertson's time."

"If any community is going to be affected by climate change," Knight said, "it would be this one, because the plants flower soon after the winter snow melts."

In many ways the most startling finding to emerge from the re-collection was that half Robertson's bees were nowhere to be found. The scientists never saw them.

Robertson's bees were mostly solitary bees, small, nondescript bees that lay a few eggs in cells and leave their young to develop on their own.

"Some of these bees have broad distributions, encompassing, for example, the entire eastern United States, so even though they're locally extirpated, most are not extinct," said Knight.

The re-collection also revealed timing mismatches between the bees and the plants. Plants were flowering earlier than they had in Robertson's time: on average. 9.5 days earlier. Bees were active earlier too: on average 11 days earlier.

But despite similar average shifts, timing mismatches occurred, because the early-season bees advanced a lot more than the late-season bees, said Knight, and no such pattern occurred among the plants.

Moreover, everything had speeded up. The flowers were in bloom eight fewer days on average and the insects flew for 22.5 fewer days. Because everything was more compressed, there was less overlap and less time for successful pollination.

Of the 532 pairings between the plants and bees that linked the subset of Robertson's network Knight and Burkle studied, 406 had been lost (but 120 new pairings had been gained). Forty five percent of the links were broken because bee species were missing, and the rest had broken for other reasons, including timing mismatches or habitat fragmentation.

A 40-year-old re-collection of Robertson's network

But Burkle and Knight were aware that counting network links was a crude measure of pollination services. "All the network diagrams say is the bee is present, the plant is present, and we saw them interacting at least once," Knight points out.

"Robertson didn't keep track of how much time he spent in the field watching each flower, so we couldn't get visitation rates from his data. But of course we searched the literature to see whether anybody had published on the Carlinville network since Robertson, and one person had."

That person turned out to be Marlin. "All through high school I studied bees and ants," he said, "and when I came to college, the Illinois Natural History Survey hired me to help collect insects around the state.

"In my senior year I was asked to collect bees at Carlinville to try to duplicate as much as possible Robertson's efforts. I spent two seasons collecting on 24 plants that Robertson had collected on."

One of the plants Marlin studied was Claytonia virginica, commonly known as 'spring beauty.' "We were very interested in Claytonia virginica because it is the plant in the network currently visited by the greatest diversity of bees," Knight said.

"Marlin's dataset gave us visitation rate, a quantitative measure of pollination we otherwise wouldn't have had. Comparing the visitation rates we measured to Marlin's, we discovered that the bees were making fewer trips to the flowers than they had in the 1970s.

"Marlin counted 0.59 bee arrivals per minute and we counted 0.14 arrivals. So even those some interactions are still present, they're weaker.

Both Robertson and Marlin had collected their bees, pinned them, and deposited them in the Illinois Natural History Survey, often still fuzzy with pollen.

To assess how much usable pollen the bees had carried, Burkle and Knight picked six bee species that frequently visited Claytonia virginica, two named by Robertson, and washed Robertson's archival specimens of those bees, Marlin's specimens and their own.

"We gave the bee a gentle bath and washed its pollen off onto a microscope slide and then we fluffed it back up with a hair dryer," Knight says.

Since these were all the same species of bee caught off the same flower, the default assumption was that they'd be covered in much the same pollen.

Not so. It turned out that these bees had been more loyal to Claytonia in the past than they were now.

The fraction of the pollen on the bee contributed by Claytonia virginica was highest in Robertson's time, lower in Marlin's time and much lower in 2010. Since pollen from another species of plant is at best unusable and at worst can clog up pistils, preventing fertilization, the bee washings also pointed to a decline in pollination services.

The bottom line

"I was surprised by how tenuous a lot of these plant-bee interactions are," Burkle said. "We've pushed on these communities a lot, and they are pretty robust, but at the same time, they are compromised, and more compromised than I was expecting them to be."

There have been major changes in Robertson's network over the past 120 years, Knight said. The good news is that the network proved flexible, and many of the broken connections were replaced with new ones. But the bad news is that network has been restructured in ways that will make it less resilient to disturbances in the future.

We can't just kick these plant-pollinator networks forever and expect them to keep functioning," Knight said.

Toxic oceans may have delayed spread of complex life

Feb. 28, 2013 ? A new model suggests that inhospitable hydrodgen-sulphide rich waters could have delayed the spread of complex life forms in ancient oceans. The research, published online this week in the journal Nature Communications, considers the composition of the oceans 550-700 million years ago and shows that oxygen-poor toxic conditions, which may have delayed the establishment of complex life, were controlled by the biological availability of nitrogen.

In contrast to modern oceans, data from ancient rocks indicates that the deep oceans of the early Earth contained little oxygen, and flipped between an iron-rich state and a toxic hydrogen-sulphide-rich state. The latter toxic sulphidic state is caused by bacteria that survive in low oxygen and low nitrate conditions. The study shows how bacteria using nitrate in their metabolism would have displaced the less energetically efficient bacteria that produce sulphide -- meaning that the presence of nitrate in the oceans prevented build-up of the toxic sulphidic state.

The model, developed by researchers at the University of Exeter in collaboration with Plymouth Marine Laboratory, University of Leeds, UCL (University College London) and the University of Southern Denmark, reveals the sensitivity of the early oceans to the global nitrogen cycle. It shows how the availability of nitrate, and feedbacks within the global nitrogen cycle, would have controlled the shifting of the oceans between the two oxygen-free states -- potentially restricting the spread of early complex life.

Dr Richard Boyle from the University of Exeter said: "Data from the modern ocean suggests that even in an oxygen-poor ocean, this apparent global-scale interchange between sulphidic and non-sulphidic conditions is difficult to achieve. We've shown here how feedbacks arising from the fact that life uses nitrate as both a nutrient, and in respiration, controlled the interchange between two ocean states. For as long as sulphidic conditions remained frequent, Earth's oceans were inhospitable towards complex life."

Today, an abundance of nitrate, in the context of an oxygenated ocean, prevents a reversion to the inhospitable environment that inhibited early life. Determining how Earth's oceans have established long-term stability helps us to understand how modern oceans interact with life and also sheds light on the sensitivity of oceans to changes in composition.
