Protecting the legitimate rights and interests of investors, especially small and medium-sized consumers, is the core task of the China Securities Regulatory Commission (CSRC), Wu Qing, chairman of the CSRC, China's top securities regulator, said in his first appearance before media during the ongoing two sessions.

"In a market like ours, where small- and medium-sized investors account for the vast majority, protecting the legitimate rights and interests of investors is the core task of the CSRC," Wu said.

Ensuring fairness and openness should be the most important principle for market regulators, according to Wu.

Corporate IPOs should never be focused on extracting money from the market and fraud should be resolutely cracked down upon, said Wu.

Wu vowed to aggressively enhance regulatory oversight on companies seeking IPOs and intermediaries in the IPO process and fix loopholes on illegal selling of shares by shareholders.

In Wu's first open appearance to media since he took his new post, Wu said he is still one day short of completing his first month's tenure at the post that oversees the world's second largest capital market.

Wu joked that "I am still learning and am a rookie," adding that he has been listening to ideas from all sides.

Key work for the CSRC will include enhancing regulatory oversight with severe punishment for violators in accordance with the law and rigorously manage the regulatory team, Wu said.

The regulator won't hesitate to act to correct extreme situations when the market seriously deviates from its fundamentals, irrational and violent fluctuations occur, liquidity is exhausted, market panic occurs and serious draining of confidence appears, Wu said.

Wu was appointed as a new chief of the country's top securities regulatory agency on February 7 amid a whirlwind week in the Chinese stock market, marked by swift efforts by the Chinese government to tackle volatility.

Since he took office, the Chinese A share market has recovered much of its recent losses, finishing at 3,039.93 points at the Shanghai bourse and 9,395.65 points at Shenzhen bourse on Wednesday.

In order to promote the healthy development of the capital market and protect investors' rights and interests, the CSRC has held symposiums to listen to opinions and suggestions on improving the basic system of the capital market, strengthening the protection of the rule of law and visiting listed firms to help them address difficulties to achieve high-quality development.

Microscopy Masters asks one thing of citizen scientists: Find proteins in electron microscope images. The task will probably give participants new appreciation for biologists who decipher the structures of teeny, tiny molecules. It’s not easy.

The goal of the online project, created by researchers at the Scripps Research Institute in La Jolla, Calif., is to improve biologists’ ability to construct detailed, three-dimensional models of proteins.

Using cryo-electron microscopy — which involves freezing, then imaging a sample — the researchers have taken thousands of photos of their current target, a protein complex involved in breaking down other, unwanted proteins. Each image contains 10 to 100 copies of the complex. It takes that many images to capture a protein from every angle. Once the 2-D images are stitched together, researchers can reconstruct the protein’s globular, 3-D shape at near-atomic resolution.
Microscopy Masters enlists volunteers to do the necessary first step of combing through the photos to find the protein molecules — a time-consuming job that people do better than computers. The task may feel daunting, as each black-and-white image resembles a fuzzy TV screen. Only some of the dark smudges in any given image will be molecules of interest; others will be actual smudges or globs of proteins too jumbled to be of use. Fortunately, a practice tutorial offers a crash course in protein identification. And each image will be classified by many users, alleviating some of the pressure of worrying about marking the wrong thing.

Data from the project will help researchers improve protein-picking computer algorithms, says project member Jacob Bruggemann. That way computers can take over the painstaking work.

SAN DIEGO — On some planets that orbit whirling stars, spring and autumn might be the best time to hit the beach, whereas summer offers a midyear respite from sweltering heat. These worlds’ orbits can take them over regions of their sun that radiate wildly different amounts of heat.

“Seasons on a planet like this must be really strange,” says Jonathon Ahlers, a graduate student at the University of Idaho in Moscow, who presented his findings June 15 at a meeting of the American Astronomical Society.
Some stars spin so fast that they bulge in the middle. That bulge pushes the equator away from the blazing core, making it much cooler than the poles. A fraction of these stars also host planets that travel on cockeyed orbits, which take these worlds alternately over the poles and equator of their sun.

Ahlers developed computer simulations to see how the differences in solar energy combined with the tilted orbits might affect a planet’s seasons. The outcome depends on how the planet’s axis is tipped relative to its orbit. For a world whose north and south poles periodically face the star’s equator, “you get a cooler summer than normal and an extremely cold winter, but spring and autumn can be hotter than summer,” says Ahlers. “You get two distinct hottest times of the year.”

How that plays out depends on how the planet is built: an atmosphere or oceans could mitigate climate extremes. Ahlers has yet to work out those details. “It’s doing a lot,” he says, “but what, I don’t really know yet.”
