Reaching a long-sought milestone, Japanese researchers have demonstrated in mice that eggs and sperm can be grown from stem cells and combined to produce healthy offspring, pointing to new treatments for infertility. If the achievement can be repeated in humans - and experts said they are optimistic that such efforts will ultimately succeed - the technique could make it easier for women in their 30s or 40s to become mothers. It could also help men and women whose reproductive organs have been damaged by cancer treatments or other causes.

Animal migration is one of the great wonders of the natural world. Monarch butterflies, Arctic terns and humpback whales, among other species, travel thousands of miles to escape harsh seasonal weather and find more hospitable climes, like New Yorkers who high-tail it for Florida when the first snowflake drops. But, unlike humans, animal species don't have airlines and highways to guide them. How do they make their amazing journeys? With the help of magnets, according to new research.

Enrollment has begun for the first clinical trial to test a therapy developed from human embryonic stem cells. The trial’s primary aim is to assess the safety of Geron Corp. ’s experimental oligodendrocyte progenitor cells, which have been in development for about a decade. They were derived from some of the earliest human embryonic stem cells ever created. Oligodendrocytes are cells that insulate nerve fibers with myelin, allowing electrical signals to be transmitted to and from the brain.

Re "Cloned Embryos Created to Match Stem Cells," May 20: When -- not if -- South Korea or another country develops viable procedures to cure Alzheimer's, diabetes, Parkinson's disease and other ills, will we here in the U.S. be able to import the benefits of stem cell research? President Bush may say he is keeping me safe from the evil terrorists; is he also going to keep me "safe" from evil science? Robert J. Schlesinger San Diego Re "Bush Objects to Stem Cell Bill," May 21: Bush states that he is against the use of "taxpayers' money to promote science which destroys life in order to save life."

One of the high-profile areas of research for stem cells is in treatment of spinal cord injuries -- and there was progress to report this week. Researchers were able to transplant a type of human cell into rats with spinal cord injuries to help the animals regain some motor function. Previous studies have shown that certain types of rat cells are necessary to repair spinal cord injuries. But the new study "brings it up to a human level," said Chris Proschel, the lead author of the paper and an assistant professor of genetics at the University of Rochester Medical Center.

Police were alerting residents in fire-scarred neighborhoods along the San Gabriel Mountains late Tuesday that rain cells expected to hit the area could cause mudslides. Advisories were issued by the Azusa and Glendora police departments for neighborhoods north of Sierra Madre Boulevard where the Colby fire burned nearly 2,000 acres in January. Several storm cells were expected around 1 a.m. Wednesday and could drop 0.25 to 0.50 inches of rain, officials said. The showers could last as long as 30 minutes each.

George Will (Commentary, Aug. 14) gives nearly reverential accolades to President Bush for consulting with bioethicists in his stem cell research decision. He applauds the president's prudence and humbleness concerning "life's mysteriousness." Maybe Bush should have consulted those same bioethicists when he decided to allow arsenic in the water, drilling in pristine wilderness areas, easing of legal pressure on the tobacco companies, bowing out of the Kyoto accord and his upcoming decision regarding the easing of laws that protect the quality of our air. Ed Silverstein Santa Monica Will's bifurcation of the two major political parties according to a "cultural cleavage" represents one of the premises upon which he builds his case that, somehow, Bush and his appointee to head a commission on biomedical ethics are bastions against a tide of "extremism" that is espoused by none other than House Democratic leader Richard Gephardt.

Injections of bone marrow cells into the heart can help heart attack patients regain pumping function, studies have shown. But such injections don't seem to work once more than a week or so has passed post-heart attack, researchers working with a National Heart, Lung and Blood Institute-sponsored trial reported Monday in JAMA, the Journal of the American Medical Assn. Physicians at five participating medical research centers treated 57 patients with infusions of cells from the subjects' own bone marrow, two to three weeks after the patients had suffered a heart attack.

For a $330,000 burger, taste testers thought the flavor fell a little flat. The hefty price tag, however, wasn't for some fancy, rare cut of meat. In fact, this meat had never so much as mooed in a previous life: It was beef grown in a laboratory. Dutch scientists Monday unveiled their ambitious research project, years in the making, with a public taste test of their cultured beef in London. Volunteer tasters sampled hamburger made from the lab-grown beef made from stem cells.

The courier arrived just after midnight with a bag of blood collected from a fresh umbilical cord. Inside the laboratory at Family Cord Blood Services in Santa Monica, a worker siphoned off red cells, leaving a dilute mixture of stem cells — a personal supply for Olivia Michelle Boyd, born 15 hours earlier in Honolulu. Her parents, Stephanie and Anthony Boyd, had agreed to pay the company $1,265 to harvest the material and $115 a year to preserve it in a stainless steel tank filled with liquid nitrogen.
