A massive algae bloom is choking China’s Yellow Sea and threatening some Olympic events. Many Chinese cities dump untreated sewage into the Sea. Rich in nutrients, the sewage makes the algae grow like crazy. The problem goes beyond the inconvenience to boaters. The growing algae changes the near-shore habitat. And when all this algae dies, the bacteria that decays it sucks oxygen out of the water, killing fish and creating a dead zone.

A million forced to flee flooding in China

Torrential downpours have severely affected nine provinces in China. China's civil affairs ministry says nearly 1.3 million people have now fled their homes in the hardest hit regions as the bad weather continues. The flooding in the Pearl river delta is the worst for 50 years. The flooding has submerged large areas of farm land and destroyed 6,600 homes in Guangdong and Jiangxi provinces. As of early Sunday morning, 55 deaths were reported.

The region normally experiences heavy rainfall about this time every year, but meteorological authorities said this was the worst in five decades.

The Tangjiashan “quake lake”
formed by a landslide during China’s devastating May 12th earthquake is draining slowly thanks to a sluice constructed by engineers there. Fears of the lake bursting from its earthen dam pushed authorities to find a quick and effective way to release the pressure building from the backed-up water. More than a million people living in the area were under threat of being inundated with millions of cubic meters of water.

As work crews start construction of a second drainage channel, engineers are closely watching downstream riverbanks and bridges for any sign of stress from the surging waters.

The 7.9 magnitude earthquake killed over 60,000 people and more than 17,000 are still missing.

An aftershock measuring 5.9 on the Richter scale caused landslides and other damage in the same areas devastated by the earthquake four days ago. At last report, some 4.8 million people were homeless, and more than 22,000 people died. Blocked roads and other damage to infrastructure have made it hard for rescuers and other aid to reach the hardest-hit cities and villages. China has asked the US for satellite images that might help locate victims and identify damaged infrastructure. And Western experts are watching carefully for any signs that China's nuclear weapons facilities, which are concentrated in the earthquake zone, have been damaged.

Keep your American Idol. I’ll settle to listening to Frog Idol.

Researchers in China have found that frogs in the wild there communicate with each other in a duet of musical tones made at ultrasonic frequencies that are beyond the hearing range of humans.

Specifically, they’ve recorded the mating calls between females and males. How’s this for setting the mood, the researchers found the romantic duets could most often be heard on rainy nights.

After recording the female portion of the duet, the researchers played back that recording to males kept in captivity. They responded by adding the male response – sort of a frog version of a duet between Barbra Streisand and Neil Diamond. The males also began leaping toward the source of the female songs.

Why is this so cool to know, besides prying into the romantic ways of Chinese frogs? It’s further proof that some animals have been able to adapt their hearing range to live successfully in their environment.

Being able to communicate at ultrasonic levels gives frogs a way to hear each other of the lower frequency noise caused by rushing river waters in their habit.

And just like human singers, the female frogs sing their portion of the duet at a higher frequency than the male frogs.

But the real lessons from these frogs may be applied in improving hearing aid technology. That’s the main purpose behind these researchers’ work.

Now if Budweiser could get its frogs to sing at ultrasonic frequencies, maybe it could sell even more beer!

Along with the devestating human toll, yesterday's earthquake in China could be devestating to the small breeding panda population in that country. The primary wildlife reserve for pandas to live in the wild is extremely close to the epicenter of the earthquake. National Geographic as full details of the situation at this link. More Science Buzz links to the earthquake can be found here.

UPDATE MAY 14: Panda people, you can breath easier again. All is well with the 86 pandas at the nature reserve at the heart of the Chinese earthquake. Electricty is still out at the preserve, but the pandas are fine.

UPDATE MAY 19: Information from the Wolong Reserve continues to be in flux. Now there are reports that five people were killed at the site and three pandas are missing. You can get full details here.

China hopes to do the right thing

With the upcoming Olympics, China is in the spotlight. The Chinese Health Ministry, scrambling to fend off cover-up allegations, issued a nationwide alert Saturday over a virus that has killed 24 children and sickened more than 4,000 others.

Enterovirus-71 can be deadly

In milder cases, EV71 can cause cold like symptoms, diarrhea and sores on the hands, feet and mouth. But more severe cases can cause fluid to accumulate on the brain, resulting in polio-like paralysis and death (the journal Genetic Vaccines and Therapy). Public health officials expect the number of cases to peak in June or July. There is no effective antiviral treatment for severe EV71 infections, and no vaccine is available. This disease also has broken out in Hong Kong, Taiwan, Singapore and Vietnam, although no deaths have been reported there.

Cover your coughs and wash your hands

The viruses mainly strike children aged 10 and younger and is easily spread by sneezing or coughing. A public awareness campaign is ongoing, stressing the need for good personal hygiene, mostly by hand washing.
