Chemical Reaction

December 2, 1991 | From Times Staff and Wire Reports
For the first time, chemists have been able to precisely control the course of a chemical reaction, forcing one potential reaction of a starting material to occur to the exclusion of all others. Although the reaction they studied was simple and of no commercial or scientific value, Stanford University scientists believe their success will be the foundation for experiments involving more important chemicals.

As a chemistry professor at USC, Arieh Warshel says he sometimes finds it difficult to convince his fellow scientists that computers have a place in experimental fields like his own. Many people, he laments, use them to make or watch movies, "but not to understand. " Though Warshel may hold a minority view on a campus with strong ties to Hollywood - visitors to his laboratory's website are informed that his animated computer simulations are not available on Netflix - he got a huge endorsement Wednesday from the Royal Swedish Academy of Sciences in the form of a Nobel Prize.
Loud music mixed with animated voices wafted down the hill into Dana Point Harbor as the research vessel Sea Explorer pulled away from the dock. It was a recent Saturday night, and patrons of the nightclub overlooking the cove were whooping it up. Aboard the boat, however, a quieter sort of revelry was about to begin. Here, huddled on the deck in their coats and scarves, a different group stood poised to celebrate the weekend.

Been inexplicably sneezing or feeling itchy recently? It could be an allergic reaction to that shiny new Canon EOS Rebel T4i camera you just bought. Canon just put out a notice telling owners of the recently released camera that some  of the units have been having chemical reactions that result in the grip changing colors and which could possibly lead to allergic reactions. The Japanese camera company says a number of units produced between late May and mid-June contained a slightly higher amount of rubber accelerator than normal.
For the first time, scientists have been able to directly view human thought processes, tracing the complex patterns of electrical and chemical reactions to small clusters of brain cells. Surprisingly, these unique glimpses of the brain at work are not the result of sophisticated new technologies that employ radioisotopes or X-rays to monitor brain activity.
Sixteen workers at an airplane parts manufacturing firm were hospitalized Thursday for minor respiratory problems after a "violent" chemical reaction produced a yellow toxic cloud, officials said. The incident, which occurred about 11:30 a.m. at Leach Corporation on Van Horne Way, forced the evacuation of about 200 people inside 10 buildings in the industrial park.

The secret of how the fruit got inside the liquid-filled, chocolate-covered cherries is almost as much of a mystery as how the ship got inside the bottle. The process by which these unique candies are created relies on a chemical reaction that actually takes place after the candy is made, says Dr. David Chisdes, an American Chemical Society member affiliated with a major candy company.

Many people acquire a taste for chili peppers because they like the thrill and enjoyment of irritating their bodies, says a professor at the University of Pennsylvania. Dr. Paul Rozin says that some people come to like the hot substance because of repeated exposure, peer pressure, and a chemical reaction much like a "runner's high."

An obnoxious cloud of gas was released Wednesday from a Sandoz chemical company factory at Schweizerhalle, the site of a major blaze that caused serious pollution of the Rhine last November, a company statement said. Around 33 pounds of pyridin, a colorless, organic solvent, was released and partially evaporated after a chemical reaction went wrong early Wednesday morning, the company said.

A chemical reaction at a fabric-printing company in Pawtucket released a noxious cloud that forced the plant and the surrounding neighborhood to be evacuated for about 2 1/2 hours. The plume formed at Slater Dye Works when a delivery truck dumped sodium hydroxide into an outdoor tank containing hydrogen peroxide, Police Det. Lt. John Clarkson said. The cloud was not dangerous by the time it dissipated into the neighborhood, officials said.

Find a dark spot on the San Diego County coastline after nightfall and you might be treated to a spectacular neon-blue light show. Bioluminescent waves, glowing electric blue as they crash ashore, have been dazzling nighttime beach visitors this week. People have been snapping photos of the otherworldly surf as it has increased in intensity over the last few days. The blue glow is caused by an algae bloom commonly referred to as a red tide. The organisms, phytoplankton called Lingulodinium polyedrum , have bloomed since late August, turning the water brownish-red in the daytime, according to UC San Diego scientists.

It's 8:15 a.m., and the meeting you're supposed to be running started 15 minutes ago, and your boss would be on the phone chewing you out except that your phone has died, which is why you can't call for someone to come fix your flat tire. Here you are, stuck at the side of the freeway, a sitting duck to get rear-ended. That's what's going on in your car. But what's going on in your brain? Stress, that's what. Your sympathetic nervous system has released a surge of norepinephrine, famously preparing you for "fight or flight" (both of which have appeal in your present circumstances)

When your lover is your muse, and his body is your instrument, the personal becomes professional. Choreographer Dwight Rhoden and star dancer Desmond Richardson broke up four years ago, but before that their 18-year romance created not only the nervy, hyper-kinetic contemporary dance company named Complexions -- a company performing Friday through next Sunday at the Dorothy Chandler Pavilion -- but also its innate stylistic diversity and much of its repertory.

Jeremy R. Knowles, the Harvard chemist who played a key role in explaining how chemical reactions are carried out within the cell and who later became dean of the university's faculty of arts and sciences at a time when it was bloated with faculty and drowning in debt, died April 3 at his home in Cambridge, Mass. He was 72 and had struggled for more than a year with prostate cancer.

In the midst of a drought, Los Angeles officials announced Friday that 600 million gallons of water must be dumped from two reservoirs that supply a swath of the city because an unexpected chemical reaction rendered it undrinkable. Silver Lake and Elysian reservoirs registered elevated levels of the suspected carcinogen bromate between June and October, the result of an unusual combination of intense sunlight, bromide naturally present in groundwater and chlorine used to kill bacteria.

Every day, we smear and spritz ourselves without a second thought. Eyes get rimmed in kohl liner, lips slicked in gloss. A dab of cologne on the neck, a dollop of body lotion on elbows and hands. We do this without so much as a glance at the ingredients listed on the backs of bottles and tubes. Even if we did, who could make sense of the jumble of unpronounceable words branded in tiny print?

The Bigeye bomb, centerpiece of President Reagan's $174-million plan to modernize the U.S. chemical-weapons arsenal, remains technically flawed despite seven years of testing, according to the General Accounting Office. In preliminary findings presented to House Foreign Affairs Committee Chairman Dante B. Fascell (D-Fla.), the GAO reported that in eight of its last nine tests by the Army, the bomb had not produced a sufficiently lethal chemical reaction at high temperatures.

Responsive to the cuckoo's note, The untaught harmony of spring: While, whisp'ring pleasure as they fly, Cool Zephyrs thro' the clear blue sky Their gathered fragrance fling.... Thomas Gray, "Ode on the Spring" * Forget about odes to spring. Neuroscience has taken the magic, not to mention the mystery, out of the poetry. That surge of optimism? Merely the serotonergic response to increased daylight. The distraction and dreaminess? The neurotransmitter dopamine is responding to light and warmth.

Data from the Cassini-Huygens spacecraft suggest that Titan, a moon of Saturn, is a world with the potential for life that was frozen in its youth, prevented by deep cold from developing into a livelier place. "Titan is the Peter Pan of our solar system. It's a little world that never grew up," said Tobias Owen of the University of Hawaii, a member of an international team monitoring the findings of the Huygens spacecraft sitting on Titan's surface.
