"Biological Computer: Stanford Researchers Discover Genetic Transistors That Turn Cells Into Computers.
Researchers at Stanford University announced this week that they've created genetic receptors that can act as a sort of "biological computer," potentially revolutionizing how diseases are treated.
In a paper published in the journal "Science" on Friday, the team described their system of genetic transistors, which can be inserted into living cells and turned on and off if certain conditions are met. The researchers hope these transistors could eventually be built into microscopic living computers. Said computers would be able to accomplish tasks like telling if a certain toxin is present inside a cell, seeing how many times a cancerous cell has divided or determining precisely how an administered drug interacts with each individual cell.
Once the transistor determines the conditions are met, it could then be used to make the cell, and many other cells around it, do a specific thing--like telling cancerous cells to destroy themselves.
"We're going to be able to put computers into any living cell you want," lead researcher at the Stanford School of Engineering Drew Endy explained to the San Jose Mercury News. "We're not going to replace the silicon computers. We're not going to replace your phone or your laptop. But we're going to get computing working in places where silicon would never work."..."

"...There's no particular disgrace in losing a technological challenge to Belgium: it's a highly industrialized country with an extremely tech savvy population. But for Belgium to outstrip California so handily in the solar department means California is doing something very wrong. California is almost 14 times the size of Belgium, and that's including the six percent of Belgium that's covered with water.
Belgium also has far less solar energy available to it, in its perch on the often-cloudy North Sea. A typical square meter of Belgium has only a little more than half the sunshine falling on it that a square meter of southern California does. To find a place in the U.S. with solar power potential equivalent to Belgium's in fact, you's pretty much have to go to Alaska.
So why is Belgium beating California's solar pants off? Almost all of Belgium's solar capacity is photovoltaic, and almost all of that installed due to feed-in tariff subsidies that up until 2012 were equivalent to about 44 cents per kilowatt-hour.
That's two and a half times the size of LADWP's proposed feed-in tariff payment, and it's an indication of the kind of measures we'll likely have to take to get our rooftop solar capacity where it really ought to be."

Yet another unexpected evolutionary twist. Normally, sperm is in direct competition with all the rest of sperm so that the strongest, fleetest wins. But in the diving beetles, ("tiny but deadly predators, at least if you're a tadpole or baby fish. More than 4,000 species live in freshwater spots around the world. Even in deserts of Arizona, where study researcher Dawn Higginson works as a postdoctoral researcher at the University of Arizona's Center for Insect Science, the beetles thrive in cattle water tanks") the sperm team up and swim attached. Why? Click here to find out.

"On Feb. 24, Ukrainian authorities made an alarming discovery: bones and other human tissues crammed into coolers in a grimy white minibus.
Investigators grew even more intrigued when they found, amid the body parts, envelopes stuffed with cash and autopsy results written in English.
What the security service had disrupted was not the work of a serial killer but part of an international pipeline of ingredients for medical and dental products that are routinely implanted into people around the world.
The seized documents suggested that the remains of dead Ukrainians were destined for a factory in Germany belonging to the subsidiary of a U.S. medical products company, Florida-based RTI Biologics.
RTI is one of a growing industry of companies that make profits by turning mortal remains into everything from dental implants to bladder slings to wrinkle cures.
The industry has flourished even as its practices have roused concerns about how tissues are obtained and how well grieving families and transplant patients are informed about the realities and risks of the business...
...Mandi Eisenbeis stood over her dad. It was a Thursday in May 2011 when she said her private good-byes at a funeral parlor in Lodi, Calif. George "Randy" Eisenbeis had died young, felled at age 57 by a methamphetamine overdose.
As she looked at him lying in the coffin, she noticed his hands were oozing blood.
Eisenbeis didn't know what had happened until later, when she learned the funeral director had sent a scathing complaint to the California Transplant Donor Network, the nonprofit organ and tissue bank that had stripped out Randy Eisenbeis' usable parts.
"To say this was simply a 'hack job' would be a compliment," Lodi Funeral Home's Michael Collins wrote in a letter accompanied by a series of graphic photos of the torn-apart corpse. "I guess we should consider ourselves lucky that you left his head and his hands for viewing, and yes, that is his severed foot in the photo to the bottom left of the embalming table."
In March the family sued the California organ bank, accusing it of fraud, mutilation of a corpse, and infliction of emotional distress.
According to call logs made of the consent process, the bank told Mandi Eisenbeis at least four times during the recorded consent process that the body would be properly put back together. She and the family couldn't give informed consent, the lawsuit charges, because those promises were lies designed to manipulate them into giving their okay.
The California Transplant Donor Network is accredited by the industry gold standard -- the American Association of Tissue Banks. According to its policies, tissue banks are required to reassemble a body out of respect for donors, their families and the professionals who handle bodies on their way to burial or cremation.
The tissue bank declined requests to comment for this story. In court filings the tissue bank has denied wrongdoing. In an earlier public statement the organization suggested that Randy Eisenbeis' corpse had been in good condition when it sent it to the morgue for autopsy. "No matter how complex the reconstruction process may be, it is a standard to which we adhere consistently," it said. "Unfortunately, we cannot speak to what may transpire once a donor's body leaves our control."
The medical examiner's autopsy findings, however, reported that Randy Eisenbeis came to him naked and skinned, with his feet "separated from the ankles."..."
