    Female Aedes mosquitoes mate only one in their lifetimes, but are pursued by males relentlessly. This led researchers to theorize that the insects have a mechanism of stopping copulation. Using fluorescent sperm and some careful camera work, the team found that when a male Aedes mosquito initiates contact, the female must extend the tip of her genitals by a fraction of a millimetre to initiate the act. Without this subtle movement, the male’s efforts fail.

    I don't like that so many presidents start construction on the white house (on our dime) just to suit themselves. It should not be allowed unless its actually necessary. And on their own dime.

    From what I have read it’s not. It’s being done through donations and his own dime.
    But just like any house sometimes you have to make improvements on it.

    A new study sheds light on how male Onthophagus orpheus dung beetles use their horns to battle for access to females, and how varying horn sizes lead to varying battle strategies. The findings help researchers “see how evolution keeps working, even in a city park.” Shown here is a male O. orpheus with prominent horns atop its thorax. (Photo by Steven King)

    During World War II, the U.S. Mint changed the composition of nickels to conserve metals for the war effort. From mid-1942 to 1945, nickels were made of 56% copper, 35% silver, and 9% manganese, known as "war nickels."

    The butter won't spread even though you keep the butter dish on the counter.

    You know what’s funny about this is I accused my wife of swapping out my brand of butter. Now I realize it’s a lot colder in the house. 🤪😂😂

    You open the crate in the morning to let out the Hell Mutt and she goes right back in and burrows under the blanket.

    Curiosity forced me to look it up.

    "Out of the fridge, a stick sits near 4°C/39°F. It feels rigid because many high-melting fats are still solid. Around 15–21°C (59–70°F) the stick yields under light pressure. That’s the common “softened” range for baking. From about 27–30°C (80–86°F) the surface turns shiny and slides. Complete liquefaction commonly lands near 32–35°C (90–95°F). The exact point shifts with brand, season, and butterfat level.

    Milk-fat crystals also change form. Freshly cooled butter can hold a brittle form that melts a bit higher. Gentle, slow cooling favors a softer form that melts lower. This is why a stick that was melted and re-chilled may spread sooner than a never-melted stick."

    Just wondering, seems the wife's better melts faster and at a lower temp then store bought.

    Apparently they are prepared to defend it by deploying troops to fight a swine flu epidemic... how you fight that with troops is beyond me

    Edit: Duh, read the article if you want to know how to fight swine flu with troops
