An international team has produced a first draft of the genome of the Japanese pufferfish Fugu rubripes , a feat that is expected to aid in understanding the human genome. The Fugu genome is thought to contain basically the same genes and regulatory sequences that are found in the human genome--with some exceptions that give the fish its unique identity.

The Patent and Trademark Office has changed its rules several times over the last decade to cope with a torrent of patent applications for human genes and gene fragments. Officials suggest that the latest changes should fix most problems and be the last that are needed. That seems unlikely.

UCLA cancer researchers have discovered a genetic "marker" in breast cancer cells that they believe may help predict which patients will do well after treatment and which will not. The ability to make such predictions would help doctors identify those who might benefit from more aggressive treatment, perhaps leading to longer survivals, said Dr. Dennis Slamon, a cancer specialist and principal author of a report appearing in today's issue of Science magazine.

Natives of India's Andaman Islands, once famed for their ferocity and unique appearance, are genetically separate from their neighbors and may be descendants of Stone Age settlers, researchers said. Analysis of DNA from samples taken in recent times and 100 years ago show the Andaman Islanders, which include a group known as the Jarawa, are genetically different from other South Asians. The islanders, who are on the verge of extinction, have a distinct language and culture.

An international team of researchers today reported "the first concrete evidence" that schizophrenia can be caused by a genetic defect. Studying seven Icelandic and British families in which 39 of 104 family members were schizophrenic, the researchers found that all the affected individuals shared a specific segment of deoxyribonucleic acid (DNA) that they believe contains the abnormal gene. Schizophrenia is a severe mental illness that affects one in every 100 people.

Genetic studies of Italians in Tuscany show that their forefathers, the ancient Etruscans, moved to Italy from what is now Turkey -- an origin that many archeologists have dismissed as unlikely. The Etruscans, who emerged about 1200 BC, reached their zenith in the 6th century BC, dominating Italy and the Mediterranean area until being assimilated into the Roman Republic about 200 BC. They provided many of the cultural underpinnings of Roman society.

A young Pakistani street performer and members of three related families have enabled scientists to make a genetic breakthrough that could lead to more effective painkillers. During his short life, the unnamed boy never felt pain. He was a local celebrity in northern Pakistan, where he astonished crowds by plunging knives through his arms and walking on burning coals. He died on his 14th birthday after jumping from a roof.

A controversial conference on genetics and crime sponsored by the University of Maryland was disrupted by demonstrators who charged that the event smacked of racism. As the meeting got under way in Queenstown, the demonstrators, who had come in vans, burst into the conference room, waving red flags and chanting: "Maryland conference, you can't hide. We know you're practicing genocide," and, "Jobs yes, racism no. Genetics conference has to go." The conference resumed after the hourlong protest.

The other day (you know, just during the normal flow of conversation) my mom informed me that her saliva is highly unusual. Back in college, she reminisced, she did this experiment that involved spitting into a tube then testing (using a chemical color change) to see if her spit could turn starch into sugar. Normal spit can: It contains an enzyme (amylase) that begins the digestion of starch way up in our mouths.

A radical new finding that genes passed on by fathers may be different from those passed on by mothers may explain many puzzling cancers and inherited diseases, researchers announced last week. The finding contradicts one of the principles of modern genetics. Dr.
