Scientists at Princeton University used 3-D printing to create a functional ear that can “hear” radio frequencies far beyond the range of normal human capability.

“The design and implementation of bionic organs and devices that enhance human capabilities, known as cybernetics, has been an area of increasing scientific interest,” the researchers wrote in the article which appears in the scholarly journal Nano Letters. “This field has the potential to generate customized replacement parts for the human body, or even create organs containing capabilities beyond what human biology ordinarily provides.”

The finished ear consists of a coiled antenna inside a cartilage structure. Two wires lead from the base of the ear and wind around a helical “cochlea” — the part of the ear that senses sound — which can connect to electrodes. Although McAlpine cautions that further work and extensive testing would need to be done before the technology could be used on a patient, he said the ear in principle could be used to restore or enhance human hearing. He said electrical signals produced by the ear could be connected to a patient’s nerve endings, similar to a hearing aid.

In cell biology, the nucleus is a membrane enclosed organelle found in eukaryotic cells. It contains most of the cell’s genetic material, organized as multiple long linear DNA molecules in complex with a large variety of proteins, such as histones, to form chromosomes. The genes within these chromosomes are the cell’s nuclear genome. The function of the nucleus is to maintain the integrity of these genes and to control the activities of the cell by regulating gene expression — the nucleus is therefore the control center of the cell. The main structures making up the nucleus are the nuclear envelope, a double membrane that encloses the entire organelle and separates its contents from the cellular cytoplasm, and the nuclear lamina, a meshwork within the nucleus that adds mechanical support, much like the cytoskeleton supports the cell as a whole. Because the nuclear membrane is impermeable to most molecules, nuclear pores are required to allow movement of molecules across the envelope. These pores cross both of the membranes, providing a channel that allows free movement of small molecules and ions. The movement of larger molecules such as proteins is carefully controlled, and requires active transport regulated by carrier proteins. Nuclear transport is crucial to cell function, as movement through the pores is required for both gene expression and chromosomal maintenance.

Although the interior of the nucleus does not contain any membrane-bound subcompartments, its contents are not uniform, and a number of subnuclear bodies exist, made up of unique proteins, RNA molecules, and particular parts of the chromosomes. The best known of these is the nucleolus, which is mainly involved in the assembly of ribosomes. After being produced in the nucleolus, ribosomes are exported to the cytoplasm where they translate mRNA. [x]

A rare optic sight, the “Brocken spectre,” which occurs when a person stands at a higher altitude in the mountains and sees his shadow cast on a cloud at a lower altitude, was observed in the Tatra Mountains in Zakopane, Poland, Thursday.

High Schooler Protests 'Slut-Shaming' Abstinence Assembly

High Schooler Protests 'Slut-Shaming' Abstinence Assembly:

girlwithalessonplan:

A West Virginia high school student is filing an injunction against her principal, who she claims is threatening to punish her for speaking out against a factually inaccurate abstinence assembly at her school. Katelyn Campbell, who is the student body vice president at George Washington High School, alleges her principal threatened to call the college where she’s been accepted to report that she has “bad character.”

George Washington High School recently hosted a conservative speaker, Pam Stenzel, who travels around the country to advocate an abstinence-only approach to teen sexuality. Stenzel has a long history of using inflammatory rhetoric to convince young people that they will face dire consequences for becoming sexually active. At GW’s assembly, Stenzel allegedly told students that “if you take birth control, your mother probably hates you” and “I could look at any one of you in the eyes right now and tell if you’re going to be promiscuous.” She also asserted that condoms aren’t safe, and every instance of sexual contact will lead to a sexually transmitted infection.

Where can I send this girl a donation for her tuition!?

historicalheroines:

I’ve created these flyers for a school activist project where I bring more attention to the women in history that have been forgotten or ignored. This blog will be an extension of those flyers where I post longer biographies of these women and other bad-ass women like them. Too often women’s achievements have been pushed aside, either by others in their lives, or else by the historians who choose to ignore them. This tumblr is dedicated to celebrating them and bringing their achievements to light!

If you’re one of those people who think that we don’t read about women in science and history classes because ‘women didn’t do anything’, you can just go set yourself on fire. ON FIRE. FLAMES.

a supermodel turned superwoman, rescuing her son and nannies from a riptide. Her bodyguard/ swimmer husband nearly died. But no big deal, her nips were showing. Clearly that is the most important detail.
