#Foodborne bacteria can cause disease in some breeds of chickens after allcontrary to popular belief the foodborne pathogen Campylobacter jejuni is not a harmless commensal in chickens
but can cause disease in some breeds of poultry according to research published in mbioâ the online open-access journal of the American Society for Microbiology.
The main implication is that Campylobacter is not always harmless to chickens. This rather changes our view of the biology of this nasty little bug says Paul Wigley of Institute for Infection and Global Health at the University of Liverpool an author on the study.

The optical communication demonstration will transfer video from the space station to a ground receiver located at NASA's Optical Communications Telescope Laboratory in Wrightwood Calif

An onboard camera system on the station will track the signal to maintain connection during the demonstration

Each OPALS demonstration will last for approximately 100 seconds as the space station equipment and ground telescope maintain line of sight.

Astronauts will harvest the plants for further investigation. With continued plant growth studies aboard the space station using facilities like Veggie crews may one day consume produce during long-term missions in low-Earth orbit
or to an asteroid or Mars. The Veggie unit's growth volume will be the largest volume available to date for plant growth on the space station
which will enable larger produce than was previously available due to size restrictions. This improved understanding of plant growth and development in microgravity has important implications for improving plant growth and biomass production On earth.

Research in 2013 led by Joanna Joiner of NASA's Goddard Space Flight Center in Greenbelt Md. demonstrated that fluorescence from plants could be teased out of data from existing satellites
According to co-author Christian Frankenberg of NASA's Jet propulsion laboratory in Pasadena Calif. The paper shows that fluorescence is a much better proxy for agricultural productivity than anything we've had before.
That's where missions with better resolution could help such as NASA's Orbiting Carbon Observatory-2--a mission planned for launch in July 2014 that will also measure solar-induced fluorescence.

Harvard university researchers Fabien Paulot and Daniel Jacob used computer models including a NASA model of chemical reactions in the atmosphere to better represent how ammonia interacts in the atmosphere to form harmful particulate matter.
Next they used the NASA GEOS-Chem model of atmospheric composition to simulate the complex chemistry that converts agricultural emissions--in this case ammonia--into fine particulate matter.

How to feed an astronaut: a talk with NASA's space food managerwhile it's not exactly five-star cuisine,
astronauts survive on more than the freeze-dried space food found in museum gift shops. To get a look inside NASA's kitchen,
I spoke last week with Michele Perchonok, Shuttle Food System manager at Johnson Space center. How has evolved astronaut food over the years?
In the beginning, we didn't even know if people could swallow in microgravity. We didn't know how much was due to the muscles contracting
and how much was due to gravity. The good news is they can eat and digest their food in microgravity.
Early astronaut food was basically tubes and cubes: pureed applesauce in a toothpaste tube or compressed cubes of sandwiches or breads or desserts.
The astronauts said it tasted OK, but it just wasn't satisfying because it wasn't close to
what they were used to. We started developing some products or taking commercial products that were appropriate
About the year 2000 when we were starting to be on International Space station up to six months,
When we started on International Space station the crew was on a four-day menu cycle.
Half the food on International Space station is U s. food and half is Russian food. We're now up to a 16-day menu cycle.
In addition, it's very difficult to transfer food from Point A to Point B. The astronauts eat their food within the food package most of the time.
We want the astronauts to be able to eat out of the food package with utensils.
If they're on International Space station there's a little suction where the garbage goes. The astronauts can sit over that,
so the crumbs will go right into the suction. All of our beverages are formulated pre. If you drink your coffee with cream and sugar,
--even though it's a wonderful and exciting opportunity--astronauts are separated from family and friends. You may crave comfort foods you grew up with,
Do astronauts determine their own menus? We have approximately 180 items on our food list.
They do have choices on shuttle. Do you want to develop your own menu? Do you want to take a menu and change a few items?
On International Space station, they get'preference bonus containers, 'which are items they like on the official food list
Many crews will host a special meal with the International Space station crew. For example, the crew that's hopefully going up in the beginning of December is hosting a meal
What are some of the most popular food items for astronauts? Shrimp cocktail is very popular.
or they forget to transfer it over for International Space station, it could get soft before it's ready.
I'm working with the astronauts. I'm developing food for Mars. It makes the job very special.
