Discovery’s next launch on Friday at 12:22 a.m



Teams at Kennedy Space Center have completed a portion of the testing of a liquid hydrogen fill and drain valve in space shuttle Discovery’s main propulsion system. The valve opened and closed when commanded five different times with no issues. This “cycle testing” of Discovery began at 6:28 p.m. EDT and finished at 6:59 p.m.

Teams are now performing a pressure test of the propulsion system, and recording the leak rate of small amounts of liquid hydrogen. Data from tonight’s tests will be brought to tomorrow’s mission management team for evaluation at the noon meeting.

NASA is targeting Discovery’s next launch attempt for no earlier than Friday, Aug. 28 at 12:22 a.m., depending on the results of the testing and a review of the data by the mission management team.

Discovery’s countdown is expected to resume at the T-11 hour point at 8:57 a.m. tomorrow.

Temporary tattoos and Henna can cause skin problems

Temporary tattoos, such as those applied to the skin with a moistened wad of cotton, fade several days after application. Many contain color additives approved for cosmetic use on the skin. However, FDA has received reports of allergic reactions to some temporary tattoos.

An Import Alert is in effect for several foreign-made temporary tattoos. According to Consumer Safety Officer Allen Halper of FDA's Office of Cosmetics and Colors, the temporary tattoos subject to the import alert are not allowed into the United States because they don't have the required ingredient declaration on the label or they contain colors not permitted for use in cosmetics applied to the skin.

Henna, a coloring made from a plant, is approved only for use as a hair dye, not for direct application to the skin, as in the body-decorating process known as mehndi. This unapproved use of a color additive makes these products adulterated and therefore illegal. An import alert is in effect for henna intended for use on the skin. FDA has received reports of injuries to the skin from products marketed as henna.

Since henna typically produces a brown, orange-brown, or reddish-brown tint, other ingredients must be added to produce other colors, such as those marketed as "black henna" and "blue henna." So-called "black henna" may contain the "coal tar" color p-phenylenediamine, also known as PPD. This ingredient may cause allergic reactions in some individuals. The only legal use of PPD in cosmetics is as a hair dye. It is not approved for direct application to the skin. Even brown shades of products marketed as henna may contain other ingredients intended to make them darker or make the stain last longer.

In addition to color additives, these skin-decorating products may contain other ingredients, such as solvents.

cholecystokinin plays an important role in the control of blood sugar.

A gut hormone called cholecystokinin (CCK) plays an important role in the control of blood sugar production in the liver, according to Canadian researchers.

"We show for the first time that CCK from the gut activates receptors to regulate glucose levels. It does so via a gut-brain-liver neuronal axis," Tony Lam of the University of Toronto said in a news release.CCK binds to local receptors on nerves of the small intestine, triggering a message to the brain which, in turn, tells the liver to stop producing glucose.

Lam and colleagues also found that rats fed a high-fat diet for a few days became resistant to CCK.
They said their findings suggest that CCK resistance, like insulin resistance, may be a major contributor to high blood sugar often seen in people with a high-fat diet. The results also suggest that drugs that target CCK receptors may help fight diabetes.

Biodefense and Bioterrorism

Terrorism refers to the use or threat of force or violence against people or property. A bioterrorist attack releases viruses, bacteria, or other germs to cause illness or death. These biological agents are typically found in nature. But they can sometimes be made more harmful by increasing their ability to cause or spread disease, or to resist medical treatment.

Biological agents spread through the air, water or in food. They can be very hard to detect, and they don't cause illness for several hours or days. Some agents can also be spread from person to person. Scientists worry that anthrax, botulism, hemorrhagic fever viruses such as Ebola, plague, or smallpox could be used as biological agents.

Biodefense involves medical measures to protect people against biological agents. This means medicines and vaccinations. It also means medical research and preparations to defend against bioterrorist attacks.

This Weekend Events in New York City

There are lots of events to enjoy this weekend in NYC, including the Hong Kong Dragon Boat Festival in Queens, Summer Streets in Manhattan, the Metropolitan Opera Summer Recital Series: Tappen Park on Staten Island, Black Gold - Bronx River Art, and the Three Kings Day Parade in Brooklyn.

Dragon Boat Festival, which features paddlers of all ages racing in 40+ foot long dragon boats.

The Met’s annual concerts in New York City parks are one of the most beloved summer traditions in the city. This year, the company will present a six-performance series of recitals in the parks of all five boroughs. All performances in the Summer Recital Series are free and no tickets are required, except for the concert at Central Park.

Scientific reasons to study climatic change at high latitudes are listed below:

Ice (including snow) is the predominant form of condensed water most of the year, both in the air and on the surface. Ice and snow scatter, transmit, and absorb sunlight and radiant heat much differently than water.

There is very little water vapor in the atmosphere, changing the impact of the atmosphere on the propagation of radiant energy, particularly radiant energy propagating upwards from the surface, and on the performance of some atmospheric remote sensing instruments.

The major "pumps" for the global ocean currents are at high latitudes, and there is good reason to believe that those pumps will be affected by climate-related changes in the atmosphere.

High latitude atmospheric processes over both land and sea must be characterized for incorporation into global climate models.
