A University of Southern California professor and colleagues from Stanford and Harvard universities were awarded the Nobel Prize in Chemistry on Wednesday for their pioneering use of computer modeling programs to help predict complex chemical reactions. Their work, which began in the 1970s, has revolutionized chemistry research, where scientists now work with computers as much as they do with test tubes. “Chemical reactions occur at lightening speed,” read an announcement from the Royal Swedish Academy of Sciences in Stockholm.

Steven Hackel has spent most of the last two decades bringing old California into the modern age. He's an expert in the baptism, marriage and burial records from the days of Spanish and Mexican rule. With a team of colleagues at the Huntington Library, Art Collections and Botanical Gardens, he's taken the information written down in the looping, 200-year-old handwriting of church scribes and created a computer database. So when Hackel heard this month about the discovery of dozens of bodies during a construction project on the site of Los Angeles' original cemetery, he started tapping on his keyboard.

Dreams defy even the dreamer, slipping away as stealthily as they arrive in a mind made credulous by sleep. But what if scientists could read our dreams by using the most advanced medical imaging machines and employing the sophisticated algorithms that flag fraudulent transactions among millions of credit card purchases? Researchers in Japan have taken an early step toward this chimerical goal by training computers to recognize the images flitting through the minds of sleepers in the earliest stages of dreaming.

Caltech researchers have produced the most sophisticated DNA-based computer yet, a wet chemistry system that can calculate the square roots of numbers as high as 15. The system is composed of 74 strands of DNA that make up 12 logic gates comparable to those in a silicon-based computer, the researchers reported Thursday in the journal Science. But the system operates a little more slowly than a conventional computer: It takes as much as 10 hours to obtain each result. The new findings mark a major change in the direction of DNA-based computing, which researchers have been working on for two decades.

PHILADELPHIA — In ancient Greece, priests gathered at the Temple of Apollo on Mount Parnassus, the better to interpret the deity-inspired prophecies of Pythia, the Oracle of Delphi. Google Inc., for all its omnipresence, is no deity, yet legions practice search-engine optimization in an effort to divine the secret algorithms that move certain websites to the top of an online search. Now comes candidate optimization, essentially the same idea applied to job seekers, with services that help them tweak their resumes so they end up at the top of a list generated by a company's computerized talent-management system.

Travelers planning to enter or leave the United States with personal computers should not do so with machines that have unregistered trademarks, according to the U.S. Customs Service. Personal computers bought abroad often include unauthorized copies of various trademarked, patented and copyrighted components. Imported items that infringe on the patent rights of products recorded with the Customs Service will not be allowed into the country.
