    …of us are involved in policing the neighborhoods, some of us build structures, some of us communicate information, some of us deal with food, some of us get rid of waste, etc.  Every cell gets a job (it’s the only example of 100% employment rates!). Now back to the cells in the fertilized egg.  As they start to learn what their specific job will be, the cells within the sphere will start to organize themselves.  After about 5 days after fertil…

  • Biology Explainer: The big 4 building blocks of life–carbohydrates, fats, proteins, and nucleic acids

    …molecules themselves break down into a surprisingly small number of building blocks. The proteins that make up all of the living things on this planet and ensure their appropriate structure and smooth function consist of only 20 different kinds of building blocks. Nucleic acids, specifically DNA, are even more basic: only four different kinds of molecules provide the materials to build the countless different genetic codes that translate into all…

    …90 percent of all genital warts, and HPV-16 and 18, which are responsible for about 70 percent of all cervical cancers. The CDC recommends that girls be routinely given the HPV vaccine at 11 and 12 years old. Those aged 13 to 26 who haven’t gotten the vaccine yet should also get it, though it will only protect them against any strains of HPV they have not already contracted. (HPV is incredibly common – about 6.2 million people contract it e…

As other mutations randomly arose and were favored by selection, milk composition became increasingly complex, incorporating nutritive, protective, and hormonal factors (Oftedal 2012). Some of these milk constituents are shunted into milk from maternal blood, some- although also present in the maternal blood stream- are regulated locally in the mammary gland, and some very special constituents are u…
