Drugs And Driving

A minuscule amount (25 micrograms) of LSD is enough to experience the effect of the drug. On low the user may experience these: Increased or decreased heart-rate and blood pressure, sweating, dry mouth, tremors, mood swings, and loss of appetite. The tremor alone can be dangerous while driving in the user making sudden turns Estimated Reading Time: 3 mins.

On PCR, LSD, and Science as a Wild Ride

And a car plying a winding two-lane highway, cutting north through rolling hills and oak valleys as it makes its way into the redwoods? The drive north through Mendocino County, toward his cabin in the Anderson Valley, was quiet and still.

The car hugged the turns and the air hung heavy, perfumed with the buckeye blooms. It was evening, and his girlfriend and coworker, Jennifer Barnett, was asleep in the passenger seat. Oligotide are DNA and RNA strands snipped short and turned into bits of nucleic acid, standard size and useful for experiments.

Mullis, a chemist, was part of the DNA synthesis group at Cetus. It was his responsibility to manufacture custom oligotide for company labs. Mullis was a bit of a loose cannon. A jerk by many accounts, including his own. He once threatened to show up at Cetus with a gun because he sensed that one coworker was making moves on another with whom he was romantically involved. But Mullis could also be playful. It was here, in the early s, that Mullis began to ponder the possibility of automated DNA replication, the steps that would eventually lead him to PCR.

The essential problem with oligonucleotides and DNA in general was that there were limits to how many standardized DNA snips one could synthesize. Replication, or amplification, got around this problem by simply copying the single strand you wanted to work with. All of the organs of all the plants and animals of Earth and organs that have never been in light of the moon or sun, will be ours to explore—to use and adapt to our needs. Our will be done on Earth as we sail off to the stars in heaven.

Simpson trial. He was working on a different problem, trying to identify a single nucleotide at a given position on a molecule of DNA—specifically, how to identify the base-pair mutation that causes sickle-cell anemia. To get to a single molecule of DNA you must first tease out a single strand.

DNA is, after all, a double helix. You can separate the strands—a natural process, one that occurs during cell division—in a lab using heat. Scientists had been doing this since the s, soon after they discovered the enzymes that repair and replicate DNA. Polymerase is one such enzyme. It copies DNA, but requires an extra strand of nucleic acid to do so. In a lab, these primers must be acquired, harvested, and made ready. The oligotide was the primer. The primers are made up of the four nucleotide base pairs you probably learned about in high school and may have since forgotten.

These base pairs provide the map to replication. They tell the polymerase when to start copying, and when to stop. At the heart of DNA sequencing, even in these early, primitive days, lies a beautiful truth: base pairs are complementary. For this reason, the standard process required only one oligonucleotide primer. But, Mullis thought, for this specific goal, what about two? Driving fast on a dark, winding road, Mullis slipstreamed into the eddy.

If he had two oligonucleotides going, what now? If they remained in the solution, the polymerase would copy them, too, following the roadmap set out by the target DNA. Mullis had a background in computer programing and often found himself drawn to automating processes in the lab. The story does not end there, however, for Mullis or PCR. PCR, in fact, was just getting started. Just what is a polymerase chain reaction? And is it different from PCR? The reaction itself is, well, a reaction: the constant building of genetic material from base pairs spurred on by polymerase, dreamed up by Mullis on that drive.

But that, too, incorrectly places too much of the credit with Mullis. Maybe it was in the air, like so much sweet buckeye scent. The chemist Albert Hofmann was there. It was only after decades, as LSD took on a life of its own in laboratories and beyond, that it dawned on Hofmann just what had happened—how it had happened to him.

Mullis believes in fate and star signs. What Tom White said about him held true. He was unafraid to very publicly, loudly, rudely hold forth with definitive conclusions based on no evidence. Not a trait associated with good science, or with scientists. Mullis also dropped a lot of acid.

I fell down through the couch into another world. After some minutes or seconds or hours Mullis noticed that time did not extend smoothly, but that it was punctuated by moments. He fell into a crack between two moments and was gone. He lay on the couch for four hours. Then he and Brad went for a car ride. He sat in the back and, going down Marin Avenue in Berkeley, felt very dizzy. He was terrified and sad.

He looked out the window and saw children in the yard. His wife at the time woke up. He looked at her in a way that spurred her to remind him that she was his wife. Time marched un-smoothly on; the system had a life of its own, outside of him, that cabin, that car, the cracks, his life, the ride, the drive. First, they needed to come up with an alternate method of amplifying and duplicating DNA.

The second, related goal was to see if real-time PCR was possible—that is, a method of PCR that was novel, faster, and could be monitored in real time. The team used a probe for the oligonucleotide to enter the polymerase, and they used a florescent dye to watch the process. Under ultraviolet light, the fluorescing oligonucleotides transferred energy, which sped up the process.

Then they added a closed-tube system and concentrated the formula. Before long, real-time PCR was at hand. Soon, PCR systems began to be used for early cancer detection. The amplification of cell DNA meant that scientists and doctors were able to see exactly when and where the cell replication cycle was occurring unchecked. No, catching crooks and cloning dinosaurs were what made PCR famous. The leap from DNA typing to genetic fingerprinting was a small one. Gross, a dissent that questions the very constitutionality of the death penalty.

The movie version swept PCR under the rug a bit. Indeed, paleontologists then were analyzing the DNA of very old species, just not that old. A similar test proved the extinct and flightless New Zealand moa unrelated to the also-flightless kiwi. And paleontologists were beginning to use such aDNA analysis on a thirteen-thousand-year-old giant sloth fossil.

To get the DNA, what was left of it, the rocks were ground up, the fossil destroyed. But a fragment was found—a base pair from an extinct tree. Another team outlined how they had extracted DNA from a termite that was twenty-five to thirty million years old, fossilized in Oligo-Miocene amber. A chrysomelid beetle in Dominican amber was also found, cracked open, sequenced, and destroyed.

And a priceless, million-year-old weevil specimen encased in Lebanese amber was taken apart, too, because of PCR. Under even ideal conditions, DNA rarely survives longer than one hundred thousand years. Lindahl was right, but ignored. Two months after his critique, Nature published a paper on the weevil extraction and DNA testing, which was later found to be contaminated. The paper had to be withdrawn, a fact that attracted much less attention than its initial publication—on the same day Jurassic Park first hit the big screen.

Still, for zoologists and ecologists, PCR has transformed how we might monitor and understand our world. Detailed maps of seed dispersals and migratory patterns that reach back through time would not be possible without the ability to test small samples scooped up in the field. It was the moonshot of our biotech age. But what have we learned since sequencing a full human genome? What next? For starters, our DNA has far fewer genes than expected: not quite twenty thousand.

And many seem to turn on, then off, or not function at all. And the ride is not smooth. It never has been smooth. Bustin, Stephen A. Glossip v. Lindahl, Tomas.
