(Press-News.org) NASA satellites are providing imagery and data on Typhoon Tembin southwest of Taiwan, and Typhoon Bolaven is it barrels northwest through the Yellow Sea. In a stunning image from NASA's Aqua satellite, Bolaven appears twice as large as Tembin.
NASA's Moderate Resolution Imaging Spectroradiometer (MODIS) instrument that flies onboard the Terra satellite captured a remarkable image of Typhoon Tembin being dwarfed by giant Typhoon Bolaven at 0240 UTC on Aug. 27, 2012. The visible image shows that the island of Taiwan appears to be squeezed between the two typhoons, while the northeastern arm of Typhoon Tembin's clouds extend over the southern half of Taiwan and sweep over Luzon, the Philippines, where it is better known as Typhoon Igme. Bolaven appears to be twice as large as Typhoon Tembin and has a visible eye. Tembin's eye appears obscured by high clouds in satellite imagery.
Typhoon Bolaven recently passed over Kadena Air Base in Okinawa, Japan as it moves northwestward into the Yellow Sea for a final landfall later this week in North Korea. Clouds from Bolaven's northeastern quadrant were blanketing Japan's island of Kyushu, which is the southwestern most island of the four main islands of Japan. The Yellow Sea is an arm of the North Pacific of the East China Sea, and it is situated between China and Korea.
On Aug. 26, NASA's Aqua satellite captured both storms in one infrared image. The Atmospheric Infrared Sounder (AIRS) instrument captured an infrared image of Typhoon Tembin southwest of Taiwan and Typhoon Bolaven entering the Yellow Sea. AIRS has been providing infrared data about cloud temperatures, and sea surface temperatures around the storm. Both storms had large areas of very cold clout top temperatures that exceeded -63F/-52C) indicating strong uplift in each storm. At the time of the image, Bolaven was moving over the Ryukyu Islands. They are a chain of islands owned by Japan that stretch southwest from Kyushu, Japan to Taiwan.
On Aug. 27, infrared imagery from NASA's Aqua satellite showed that Bolaven maintained tightly-curved banding of thunderstorms that were wrapping into a well-defined and large low-level circulation center. The center of circulation is as large as 550 nautical miles in diameter!
Typhoon Bolaven in the Yellow Sea
On Aug. 27, 2012, Typhoon Bolaven was moving through the Yellow Sea. Its maximum sustained winds were down to 70 knots (80.5 mph/129.6 kmh). Bolaven was located approximately 380 nautical miles (437.3 miles/703.8 km) south-southwest of Seoul, South Korea, near 32.2 North and 125.0 East. The typhoon is moving to the north-northwestward at 16 knots (18.4 mph/29.6 kmh) and creating high seas of 43 feet (13.1 meters).
Bolaven is expected to weaken as it moves into cooler waters in the Yellow Sea. It is also expected to run into stronger wind shear. Bolaven is expected to make landfall in southwestern North Korea on Aug. 28.
Typhoon Tembin Ready to Move North
Typhoon Tembin completed its cyclonic loop south of Taiwan, and is now poised to move northeast and pass Taiwan on its journey behind Bolaven, into the Yellow Sea. On Aug. 27 at 1500 UTC (11 a.m. EDT), Tembin had maximum sustained winds near 65 knots (75 mph/120.4 kmh) making it a minimal typhoon. It was located about 240 nautical (276 miles/444.5 km) miles south-southwest of Taipei, Taiwan near 21.6 North and 120.4 East. It was moving to the east-northeast near 14 knots (16.1 mph/26 kmh). AIRS infrared data showed that Tembin showed an eye covered by central dense overcast, as correlated by the MODIS visible imagery.
Tembin is expected to move north past Taiwan over the next couple of days, and track through the Yellow Sea. Tembin's final resting place will be a landfall in southeastern China, near the North Korea border by the weekend.

Plants unpack winter coats when days get shorter
2012-08-28
EAST LANSING, Mich. — Mechanisms that protect plants from freezing are placed in storage during the summer and wisely unpacked when days get shorter.
In the current issue of the Proceedings of the National Academy of Sciences, Michael Thomashow, University Distinguished Professor of molecular genetics, demonstrates how the CBF (C-repeat binding factor) cold response pathway is inactive during warmer months when days are long, and how it's triggered by waning sunlight to prepare plants for freezing temperatures.
The CBF cold response pathway was discovered by Thomashow's ...
Parents and readers beware of stereotypes in young adult literature
2012-08-28
COLUMBIA, Mo. — A newly defined genre of literature, "teen sick-lit," features tear-jerking stories of ill adolescents developing romantic relationships. Although "teen sick-lit" tends to adhere to negative stereotypes of the ill and traditional gender roles, it also explores the taboo realm of sexuality, sickness and youth, says the University of Missouri researcher who named the genre in a recent study. Readers and their parents should be aware of how the presentation of disease and disability in these stories can instill prejudices and enforce societal norms in young ...
Divorced parents in hostile relationships use technology to sabotage communication, MU study finds
2012-08-28
COLUMBIA, Mo. – Separated and divorced couples are increasingly using emails, texting and social media to communicate with their ex-partners about their children. However, when ex-spouses use that technology to withhold or manipulate information, the children are the ones who suffer most, according to a University of Missouri family studies expert. A new study suggests divorce counselors should teach separated parents effective ways to use communication technology in order to maintain healthy environments for their children.

Speaking 2 languages also benefits low-income children
2012-08-28
Living in poverty is often accompanied by conditions that can negatively influence cognitive development. Is it possible that being bilingual might counteract these effects? Although previous research has shown that being bilingual enhances executive functioning in middle-class children, less is known about how it affects lower income populations.
In a study forthcoming in Psychological Science, a journal of the Association for Psychological Science, psychological scientist Pascale Engel de Abreu of the University of Luxembourg and colleagues examine the effects of speaking ...

Working moms spend less time daily on kids' diet, exercise, study finds
2012-08-28
When it comes to cooking, grocery shopping and playing with children, American moms with full-time jobs spend roughly three-and-half fewer hours per day on these and other chores related to their children's diet and exercise compared to stay-at-home and unemployed mothers, reports a new paper by a Cornell University health economist.
Male partners do little to make up the deficit: Employed fathers devote just 13 minutes daily to such activities and non-working fathers contribute 41 minutes, finds the study, which will be printed in the December issue of Economics and ...
Accuracy of narrow band imaging with colonoscopy allows for distal non-cancerous polyps to be left in place
2012-08-28
OAK BROOK, Ill. – August 27, 2012 – According to a new study, the use of narrow band imaging (NBI) during colonoscopy is sufficiently accurate to allow distal hyperplastic (non-cancerous) polyps to be left in place without removal and small, distal adenomas (pre-cancerous polyps) to be removed and discarded without pathologic assessment. These findings validate NBI criteria based on color, vessels and pit characteristics for predicting real-time colorectal polyp histology. The study appears in the August issue of GIE: Gastrointestinal Endoscopy, the monthly peer-reviewed ...
Scientists find oldest occurrence of arthropods preserved in amber
2012-08-28
An international team of scientists has discovered the oldest record of arthropods—invertebrate animals that include insects, arachnids, and crustaceans—preserved in amber. The specimens, one fly and two mites found in millimeter-scale droplets of amber from northeastern Italy, are about 100 million years older than any other amber arthropod ever collected. The group's findings, which are published today in the Proceedings of the National Academy of Sciences, pave the way for a better evolutionary understanding of the most diverse group of organisms in the world.

New maps may reduce tourism impacts on Hawaiian dolphins
2012-08-28
DURHAM, NC – Over-eager eco-tourists intent on seeing spinner dolphins up close may inadvertently be disturbing the charismatic animals' daytime rest periods and driving them out of safe habitats in bays along Hawaii's coast.
Scientists at Duke and Stony Brook universities have developed a promising new tool that may help to limit repeated human disturbances and help reduce their negative impacts on the dolphins.
"Using the maps produced through this study we can identify the bays where the effects of human activities on spinner dolphins should be monitored most closely, ...
In war with 'superbugs,' Cedars-Sinai researchers see new weapon: Immune-boosting vitamin
2012-08-28
LOS ANGELES — Aug. 27, 2012 –Cedars-Sinai researchers have found that a common vitamin may have the potential to provide a powerful weapon to fight certain "superbugs," antibiotic-resistant staph infections that health experts see as a threat to public health.
The research, published in the September 2012 edition of The Journal of Clinical Investigation, found that high doses of the nicotinamide form of vitamin B3 stimulated a specific gene (CEBPE), enhancing white blood cells' ability to combat staph infections, including methicillin-resistant Staphylococcus aureus ...
