Curing Disease with Nanotechnology

Inching towards clinical trials.

“Our lab is creating biological nano-machines,” says Dr. Peer. “These machines can target specific cells. In fact, we can target any protein that might be causing disease or disorder in the human body. This new invention treats the source, not the symptoms.” Dr. Peer’s recent paper reported on the device’s ability to target leukocytes (immune cells) in the guts of mice with ulcerative colitis. Calling his new invention a submarine, Dr. Peer has developed a nano-sized carrier which operates like a GPS system to locate and target cells. In the case of Crohn’s disease, for example, it will target overactive immune system cells in the gut. In other diseases such as cancer, the submarine can aim for and deliver material to specific cancer cells, leaving the surrounding healthy cells intact. While other researchers are working in the area of nano-medicine and drug delivery, Dr. Peer’s submarines are among the first to combine a drug candidate with a drug delivery system. As the submarines float through the body, they latch onto the target cell and deliver their payload, a drug based on RNAi. This new kind of drug can affect faulty RNA machinery and reprogram cells to operate in normal ways. In essence, RNAi can essentially restore health to diseased cells or cause cells to die (like in the case of cancer cells).…

A Pack or a Herd?

Amanda Ripley commenting on why there was no panic on the US Airways flight that splashed into the Hudson:

He asked again and again why people had not become violent and hysterical, until the survivor agreed it was shocking indeed.

The truth is, in almost every disaster I have studied, people treat each other with kindness and respect. Violence and panic are extremely rare. An instant camraderie springs up between strangers--on a sinking ship or a bombed-out subway car. That is the rule, not the exception.

After the terrorist bombings on the London transit system on July 7, 2005, which killed 52 people and wounded hundreds, some victims actually resisted leaving the tube station. “I needed the [others] for comfort,” one survivor explained to U.K. psychologist John Drury. “I felt better knowing that I was surrounded by people.”

One study of U.S. mining disasters found that miners tended to follow their groups even if they disagreed with the group’s decisions. Grown men trapped underground would rather make a potentially fatal decision than be left alone.

In other airplane crashes, passengers have risked their lives because they climbed over seats to regroup with the rest of their family before evacuating. In skyscraper fires, people making arduous journeys down hundreds of stairs will tend to insist that those entering the stairwell from lower floors go ahead of them. In fact, I’ve yet to meet a 9/11 survivor who didn’t help or receive help from a stranger on the way out of the towers.

Why don’t we turn into raving maniacs? Because it is in our interest to be nice to each other. Under threat, we need each other more than ever.

I don't disagree with her last comment, but I think there's more to it than that.

I suspect the likelyhood of someone living through a disaster, whether man-made or natural, are statistically lower today than at anytime in man's history. And when we do encounter disasters, they're substantially more survivable today than at any other time in our history.

However, it still doesn't hurt for a civilization's culture to set some expectations of what's acceptable or not. The phrase, "Women and children first!" wouldn't exist without the prevalence of the "me first" attitude. Woe unto us if the "me first"'s win the day. It can happen and would be a defining benchmark in our civilization's decline.

Rich People versus Government

All Government is Corrupt:

Warren Buffett and Bill Gates, with about $60 billion in assets each, are America’s richest men. With all that money, what can they force us to do? Can they take our house to make room so that another person can build an auto dealership or a casino parking lot? Can they force us to pay money into the government-run retirement Ponzi scheme called Social Security? Can Buffett and Gates force us to bus our children to schools out of our neighborhood in the name of diversity? Unless they are granted power by politicians, rich people have little power to force us to do anything.

A GS-9, or a lowly municipal clerk, has far more life-and-death power over us. It’s they to whom we must turn to for permission to build a house, ply a trade, open a restaurant and myriad other activities. It’s government people, not rich people, who have the power to coerce and make our lives miserable. Coercive power goes a long way toward explaining political corruption.

And to summarize what I've always said:

The only way to reduce corruption and money in Washington is to reduce the power politicians have over our lives.

Grape Seed Extract Kills Leukemia Cells

Awesome:

More than three-quarters of laboratory leukemia cells exposed to an extract from grape seeds died within 24 hours, effectively killing themselves while leaving other cells unharmed, a new study shows.

University of Kentucky researchers say they found that the extract activates JNK, a protein that regulates the cell-signaling pathway the leads to cell death, or apoptosis.



Faster please.
