In case you missed it, another male congressman has made outrageous claims about rape. This time it was Rep. Trent Franks (AZ) who during a House Judiciary heading said he opposed abortion exceptions for rape victims because “the incidence of rape resulting in pregnancy is very low.” LIKE if you agree with Toni Morrison that rape is rape and should be taken seriously.
Damn, this Periodic Table is Beautiful
Say hello to your new desktop background.
In May 1949, LIFE Magazine published a stunning series of images to accompany an issue dedicated largely to The Atom. You can check out the feature in its entirety here, but the reimagination of the periodic table of elements as a colorful spiral is easily one of the most striking graphics of the lot. [Click here to see it in hi-res]
Here in its entirety is the caption that accompanied the original graphic:
The irregular spiral above is a systematic arrangement of the 92 natural elements, the four new elements so far created by man and eight more elements which is theoretically possible to create. It is called the periodic table of the elements. The sequence begins with hydrogen (at the center of the spiral), which is the first and simplest element. Under its name appears its chemical symbol (left), its atomic weight (right) and a larger numeral which gives the total number of electrons in its atom. It is on the basis of this number that the elements are arranged in sequence: after hydrogen, with its single electron, come helium with two, lithium with three, beryllium with four and so on around the spiral.
The colors and construction of the table express another kind of relationship among the elements: the repetition, at regular intervals, of the chemical properties of the first few. Characteristics are thus repeated periodically in the progression form the simplest to the most complex. The table is so organized that elements whose chemistry is almost identical are grouped together in blocks of connected by solid arrows (all the inert gases–helium, neon, etc.–fall in the single gray block at the left). Broken arrows relate groups of elements which are similar in most respects but differ in a few of their properties. All related elements are given different shades of the same color. The key to this similarity among elements is found in the arrangement rather than the number of the electrons in their atoms. Only the electrons in the outer shell affect an atom’s chemical nature. Therefore all elements whose atoms have identical outer shells are chemically related, regardless of the total umber of electrons which each of them may possess. For example, lithium, sodium and the other elements in the red segment at left all have one electron in their outer shells and are therefore similar though they differ in the total number of their electrons. Each complete circuit of the table starts with one of these elements and ends with an element in the adjacent gray segment whose atom’s outer shell is complete.
This table, like all attempts to reduce the basic phenomena of nature to a simple pattern, falls somewhat short of its objective. For one thing, there are variations in the sequence of elements which do not fit readily into its graphic form. For another, it is not so much a simplification as an orderly presentation which specifies the relationship between elements but leaves much about them to be explained… Yet in expressing this relationship the table reveals the extraordinary symmetry and order which underlie the universe.
Khan Academy, a nonprofit educational website, is running an MCAT prep video contest for medical students. They’re looking for medical students to help other students prep for the new MCAT. The deadline is June 16, and winners receive an all-expenses-paid one-week trip to get face-to-face training and support from Khan Academy to help develop an open access, free resource for students and faculty in the health professions.

Avocado Lime Tequila Paletas
Depending on the size of your molds, this will make about 10 popsicles
1 cup water
½ cup sugar
zest of 4 limes – about 2 Tablespoons
5 ripe soft avocados
1/3 cup lime juice (about 4-5 limes)
2 ½ Tablespoons tequila
½ teaspoon kosher salt
Combine the sugar and water in a small saucepan and boil until the sugar is fully dissolved.
Add the lime zest and let cool to room temperature. Strain into a bowl (to remove the zest) and for best results, chill for several hours.
Cut the avocados in half and remove the flesh. Add to a blender with the lime juice, tequila and salt and process until smooth. If you need a little more liquid to get things moving, add some of the lime simple syrup.
Add the avocado mixture to the simple syrup and stir until well blended.
Pour into popsicle molds and freeze until solid, at least 4 hours. To remove from the molds, run warm water along the outside and carefully ease out of the cavities.
For longer storage, remove from the molds, wrap individually in plastic wrap, place in a large Ziploc bag and store in the freezer.
