Genome at Home: Biohackers Build Their Own Labs. This homemade machine from OpenPCR amplifies DNA samples—just like a professional device. Photo: Justin Fantl is not an ideal space for a high tech biofabrication facility. To get to the one Josh Perfetto is putting together, visitors must walk all the way to the back of his mostly unfurnished house in Saratoga, California—through the kitchen, past some empty rooms, across a den with a lone couch—then climb a poorly lit staircase and round a corner. The room itself is about 120 square feet and has one big window with a view of an adjacent roof. There’s an 8-foot-wide gap in the middle; the rest of the room is for science. He laughs a little awkwardly, and it’s easy to see why he’s worried. “I’ve been sleeping in here,” says Mackenzie Cowell, Perfetto’s business partner. And the home audience is their target market.
Science is all about coming up with smart ways to answer hard questions. But PCR machines are only the beginning. Another example: Cathal Garvey’s DremelFuge. 1 2 View All. Bjarke Ingels Group.

Magnetotactic bacteria (or MTB) are a polyphyletic group of bacteria discovered by Richard P.
Blakemore in 1975, that orient along the magnetic field lines of Earth's magnetic field. To perform this task, these bacteria have organelles called magnetosomes that contain magnetic crystals. The biological phenomenon of microorganisms tending to move in response to the environment's magnetic characteristics is known as magnetotaxis (although this term is misleading in that every other application of the term taxis involves a stimulus-response mechanism). In contrast to the magnetoception of animals, the bacteria contain fixed magnets that force the bacteria into alignment — even dead cells align, just like a compass needle.[1] The alignment is believed to aid these organisms in reaching regions of optimal oxygen concentration.[2] Introduction[edit] Biology[edit] Magnetotactic bacteria produce their magnetic particles in chains.

Notre Dame research plays prominent role in alternative stem cell method. President Obama’s decision to sign an executive order Monday easing restrictions on federal funding for embryonic stem cell research comes on the heels on an announcement last week in the journal Nature of a promising alternative to embryonic stem cells.
Research by University of Notre Dame biologist Malcolm J. Fraser Jr. provided a crucial key in establishing the practicality of the alternative method. (Stem cells) are the body’s master cells, producing all of its tissues and organs. They offer hope for regeneration of tissues and even organs and for curing many diseases. In the new technique, a team of Canadian and Scottish scientists used a movable piece of genetic material called "piggyBac," which was discovered and patented by Fraser, to coax skin cells of mice and humans into a state that appears biologically identical to embryonic stem cells. PiggyBac is a piece of DNA known as a transposon that can insert itself into the genetic machinery of a cell.
