BEIJING, July 19 (Xinhua) -- China's northern coast will experience a storm surge from Tuesday evening to Wednesday, said China's National Marine Environmental Forecasting Center.
The center issued yellow warnings, third in the four-color warning system, for the ports of Qinhuangdao and Jingtang in north China's Hebei Province and blue warnings to other coast regions in Tianjin, Hebei and Liaoning.
The elevation may range from 50 to 150 cm and the peak is likely to arrive on Wednesday afternoon, the center statement said.
Meanwhile, waves measuring three to four meters will occur in the northern part of the Bohai Sea and Yellow Sea.
Several popular summer resorts along the coast have attracted a large crowd of tourists. The center urged them to stay away from the shore.
China’s Wu Dajing in action en route to winning the 500-meter short track speed skating final at the Asian Winter Games in Sapporo yesterday.
China claimed two gold medals in short track speed skating at the Asian Winter Games yesterday while Japan won four titles in speed skating.
Wu Dajing , who won silver in the men’s 1,500 meters on Monday, won gold in the men’s 500 meters in a time of 40.764 seconds, edging South Korea’s Seo Yi-ra by .078 seconds. Park Se-yeong was third in 41.182.
“The race was quite difficult,” said Wu , a two-time world champion in the 500. “The South Koreans pressured us a lot over the final two laps and I almost lost my balance on the final lap.”
Wu’s compatriot Zang Yize won gold in the women’s 500, clocking a time of 43.911. Ayuko Ito of Japan was second in 44.236 while Choi Min-jeong of South Korea took bronze in 44.819 after her compatriot Shim Suk-hee got tangled up on the final lap with Fan Kexin of China and both were disqualified.
Nao Kodaira of Japan earned her second gold of the Sapporo Games by beating two-time Olympic champion Lee Sang-hwa of South Korea in the women’s 500 on the long track.
Kodaira is unbeaten in six World Cups this season, and the winner of the 1,000 on Monday. “I wasn’t at my best today, maybe 80 percent of full fitness ,” Kodaira said. “But I wanted to race against a strong sprinter and it was good preparation (for the 2018 Winter Olympics).”
Takuro Oda won the men’s 1,000, and Miho Takagi the women’s 1,500.
The Japanese team of Misaki Oshigiri, Nana Takagi , and Ayano Sato cruised to victory in the women’s team pursuit. South Korea was second, and China third.
In cross-country skiing, Japan also captured the women’s 10-kilometer free title through Yuki Kobayashi. Lee Chae-won of South Korea was second, 24.4 seconds back, and Yelena Kolomina of Kazakhstan was third.
Rinat Mukhim won Kazakhstan’s first gold of the games by winning the men’s 15-kilometer free , 4.5 seconds ahead of Naoto Baba of Japan. Akira Lenting, also of Japan, was third.
Elsewhere, the men’s ski jumping event was cancelled to due to high winds.
SAN FRANCISCO, Sept. 23 (Xinhua) -- Researchers in the United States and Germany have discovered a part of protein molecules that could be key to find how proteins interact with each other inside living cells to carry out specialized functions.
Named by the researchers as "add-ons ," because they work the way that computer software add-ons customize a web interface with a user, the tiny bits of molecular material on the outer edges of the protein interface are found to be able to customize what a protein can do.
Proteins are known to have an interface region where they connect with other proteins. However, before the new findings published in the Proceedings of the National Academy of Sciences, or PNAS, it was not clear how key proteins are able to find each other within a cellular environment that may contain tens of thousands of other proteins.
The researchers at the Ohio State University in the United States and the University of Regensburg in Germany experimented with live bacteria , determined that in the organism Bacillus subtilis, or B. subtilis, in which a unique interface add-on is missing, bacteria colonies grew 80 percent less under certain conditions. The reason for this was that the missing interface add-on led to un-healthy cross-interactions of proteins in the B. subtilis cells.
The University of Regensburg team, led by computational biologist Rainer Merkl and protein biochemist Reinhard Sterner , analyzed the protein sequences derived from more than 15,000 bacterial and archaeal genomes on a large computer cluster, sorted proteins that shared common evolutionary ancestors into a kind of family tree, and compared individual proteins to their protein "relatives," thus leading them to spot interface structures that were present in some proteins but missing in others.
The Ohio State team then used native mass spectrometry to detect how the presence and absence of add-ons influenced the ability of proteins to interact with each other.
"We're really pleased that our native mass spectrometry technology could help identify the role of these interface 'add-ons' - a way for a protein to find its critical partner protein even in a crowded cellular environment with similar structures present ," Vicki Wysocki, director of the Campus Chemical Instrument Center at Ohio State, was quoted as saying in a news release.
It is difficult to overstate the importance of proteins to life as we know it, according to the researchers. Enzymes are proteins that enable chemical reactions in cells; antibodies are proteins that bind to foreign invaders in the body. The list goes on to include thousands of critical functions. In most cases, proteins have to connect to each other and form groups called protein complexes to perform diverse tasks.
