In a tropical cyclone, strong uplift of air pushes the tops of thunderstorms high into the troposphere. When that strength wanes, the cloud tops drop and become less cold. That's because the higher you go in the troposphere, the colder it gets. NASA satellite infrared data has revealed that Tropical Storm Tony's cloud top temperatures are warming and the storm is weakening. The Atmospheric Infrared Sounder (AIRS) instrument aboard NASA's Aqua satellite captured infrared imagery of Tropical...
New E-Scoop glasses improve way of life for patients suffering with macular degeneration (ARMD).

On the road at night or on a tennis court at dusk, the eye can be deceived. Vision is not as sharp as in the light of day, and detecting a bicyclist on the road or a careening tennis ball can be tough. New research reveals the key chemical process that corrects for potential visual errors in low-light conditions. Understanding this fundamental step could lead to new treatments for visual deficits, or might one day boost normal night vision to new levels. Like the mirror of a telescope...

Typhoon Prapiroon is the twenty-second tropical cyclone of the western North Pacific Ocean, making for a very active season. NASA's Terra satellite passed over the storm as it was intensifying into a typhoon and noticed very tight circulation with bands of thunderstorms wrapping into the center. Tropical Depression 22W was born on Oct. 7. On Monday, Oct. 8, the twenty-second tropical cyclone had organized and strengthened into Tropical storm Prapiroon. At that time it was located about 600...

Forecasters know that Tropical Storm Nadine is a fighter as it continues to stay alive in the eastern Atlantic Ocean. Even satellite imagery shows Nadine's fighting spirit, because although Nadine is now a tropical storm, infrared data clearly shows that Nadine maintained an eye early on Oct. 2. At 11 a.m. EDT on Oct. 2, Nadine remains a tropical storm and appears to be weakening. Nadine's maximum sustained winds were near 65 mph (100 kph). The center of Tropical Storm Nadine was located...
One day ago, Super Typhoon Jelawat's eye was about 25 nautical miles in diameter, today, Sept. 27, NASA satellite data indicated that eye has grown to 36 nautical miles! The latest infrared image from the Atmospheric Infrared Sounder (AIRS) instrument that flies on NASA's Aqua satellite shows a clear eye in Typhoon Jelawat on Sept. 25. The cloud top temperatures of the thunderstorms surrounding the eye exceed -63 Fahrenheit (-52 Celsius) indicating that they are very powerful and heavy...

The Zonules of Zinn, also known as Zinn’s membrane and ciliary zonule, is a ring of fibrous strands connecting the ciliary body with the crystalline lens of the eye. The zonule of Zinn is split into two layers: a thin layer, which lines with the hyaloid fossa, and a thick layer, which is a collection of zonular fibers. Together, these fibers are known as the suspensory ligament of the lens. When color granules are displaced from the Zonules of Zinn, by friction against the lens, the...
Location A: This is known as the Eye or the center of the Hurricane/Typhoon/Cyclone. This region is highlighted by the potential for calm winds and also the fact that it’s possible to see the sun or moon during the night. It also gives people false sense that the storm may be done, when in fact it is only at the half way point. Location B: This region is known as feeder bands that outline the center of the storm. In this region you will see very strong winds and also tornadoes and heavy...
Tropical Cyclones have a life cycle they go through. The first stage is referred to as a wave when the satellite imagery picks up on an area of thunderstorm developing in the ocean in the tropical region. If the thunderstorms hold together and get better organized it will then get upgraded to a tropical depression. During this stage of its life it will have a better organization to its thunderstorms and also the winds will be increasing. The third stage that occurs is the formation of a...
Tropical systems are weather features that form in the tropics and can become very intense areas of low pressure that impact many coastal regions throughout the world. They usually form between 5 and 15 latitude. This is because a tropical system is a vertical extension in the atmosphere of a large thunderstorm development. In order for these thunderstorms to move they need something in the upper levels to help them move. That is where the spinning of the earth comes into play for them which...
