I almost missed it but today, May 23, 2014, is indeed World Turtle Day, a day to celebrate all our shelled reptilian friends, who, by the way, have evolved a pretty successful survival strategy. Yay!

Hatch today?

by Liza on May. 19th, 2011

Well, it's May 19, the estimated hatch date for the peregrine falcon chicks in the nest box at the King power plant in Bayport. Haven't seen any chicks yet, but Belinda's made a little moat of pebbles around the eggs -- the folks on the Raptor Resource forum say that's something she always does right before hatching. Stay tuned...

More than half a billion eggs were recalled after Salmonella sickened over 1600 people (according to the Center for Disease Control, or CDC in September.) That’s a lot of eggs, and a lot of sick people.

What is this nasty bacteria that makes us wonder whether we should let our kids eat raw chocolate chip cookie dough, even as we sneak several spoonfuls when they’re not looking?

Salmonella enterocolitis is one of the most common types of food poisoning and is caused by the bacteria Salmonella Enteriditis. You can get a Salmonella infection by swallowing food or water that is contaminated with the salmonella bacteria. Often, the culprit is surface contamination from raw chicken and raw or undercooked eggs. In most people, it causes diarrhea, fever and abdominal cramping, but young children and those with weakened immune systems are at greater risk of dehydration and more serious infections.

Why don’t they just wash the eggs better? Salmonella bacteria live in the intestinal tracts of animals and birds and can infect the ovaries of healthy-looking chickens. This allows bacteria to infect the eggs even before the shell is formed and voila- you have a pathogen that can’t be washed off of the egg because it’s inside. Salmonella bacteria are often found in the “white” of an egg, although they can migrate to the yolk as the raw egg sits in your refrigerator. Organic and free range chickens have less disease than factory-”farm” raised chickens, partly because of healthier diets and less crowding. Cooking eggs until the yolk is solid kills Salmonella bacteria.

How can you make your cookie dough and eat it too? Buy pasteurized eggs (you can find them at most grocery stores) that have been heat-treated to kill bacteria, but are still essentially raw for all cooking and baking purposes.

Also, remember to wash cutting boards you’ve cut meat on with soap and water before cutting anything else on them, or just have separate cutting boards for meat. Don’t forget to wash your hands after handling raw eggs! Pet food and reptiles can also harbor salmonella bacteria, so have your kids wash their hand after handling either!

Bacteria are everywhere. Some keep you healthy and some make you sick, but making good decisions in the kitchen can keep you and your family from being affected by food-born illness!

"Female Gouldian finches 'decide' to have more male chicks if they are less compatible with their mate.

The birds, which have either red or black heads, prefer to mate with males with the same head colouring, as this signifies a better genetic match.

Chicks from a mismatched mating - particularly the females - are weaker and more likely to die very early.

A report in the journal Science says that the birds compensate for this by having more male chicks in their brood.

Join the ongoing discussion about whether or not humans should use technology to select the sex of offspring when a genetic roll of the dice is a risky proposition.

Spring is springing, and birds are nesting, and you can be a part of the Cornell Lab of Ornithology's NestWatch project. They provide the training. You can observe natural nest sites or nest boxes, and your observations get permanently archived in North America's largest breeding bird database. The data collected helps scientists better understand threats to bird species. Pretty cool.


hey, does anyone know when to start eating the eggs from young chickens? Mine have started laying small eggs and I have noticed that the whites are sort of milky and gelatinous, and not clear and runny like store bought eggs. Is this normal? Of course I'm asking after I just ate several of them. They tasted ok, but would love some feedback of anyone is in the know.


On Saturday, May 26, Buzz blogger Thor Carlson emailed the staff here at the Science Museum of Minnesota that our resident peregrine falcon Athena's first egg had hatched:

Athena the peregrine falcon was quite agitated this morning and I think midday we had our first hatching. Something fuzzy seems to be fluffing out from under her and than about 2 p.m. I saw her picking her beak through half of an egg shell. With the weather being pretty drippy today, she's likely keeping the little one underneath her with the three other eggs.

Stop on up at the Mississippi River Gallery and check out the latest developments...more falcon chicks should be on the way.

Three new mouths to feed: This shot, captured late Monday (5/28) afternoon, shows three new chicks. Athena's going to be busy...

The city of Chicago is looking for volunteers to go on a wild goose chase. The city has been plagued for over a decade by an ever-growing flock of Canadian geese. The birds have virtually taken over some city parks, harassing users and covering the ground with their droppings.

The city wants volunteers to find goose eggs during the nesting season. Then, wildlife control experts will shake the eggs to destroy the embryos. The geese will continue to incubate the eggs (and not lay new ones), but no goslings will hatch. Experts claim this is a more humane form of animal control than rounding up wild geese and killing them.


Drugs manufactured in eggs and milk.

Farm animals are being modified genetically to produce milk and eggs containing pharmaceuticals. Just after ferilization "Pharmers" insert into the embryo human genes for producing proteins needed to treat humans unable to produce their own. They attach that DNA code with a gene that codes for a sugar found in milk. The therapeutic protein will then be produced within the animals milk.

Pharm animal drug approved

GTC Biotherapeutics anti-clotting agent, ATryn, is the first government-approved drug from transgenic animals. It replaces human protein antithrombin, which helps prevent blood clots that could lead to a stroke or heart attack. About one in every 5,000 people has a genetic deficiency of this protein. One goat can produce a kilogram of antithrombin each year. It would take 50,000 people to donate that same amount.

Chickens can lay medicinal eggs

Chickens can also be modified to produce human proteins in the albumen of their eggs. Origen Therapeutic scientists hope to breed a chicken that will produce the entire range of human antibodies in its eggs.
