Cheree Osmanhodzic's wedding website lives on. Engagement photos show her lovingly embracing fiance Adam Culvey. Their proposal story recounts how he knelt on one knee to present a ring after a hike overlooking the Ojai Valley. And the couple wrote excitedly of plans to honeymoon in the Caribbean. Tuesday should have marked their 263rd day as newlyweds, according to the website, which continues to count each day since their planned Sept. 24 wedding. Instead, Culvey watched his fiancee's killer plead guilty to fatally stabbing Osmanhodzic last year during a burglary at their Valley Village home, just two months before the couple were to exchange vows.

At a time when so many people are trying to clean out their systems with detoxifying pads, pills and gadgets, let's take a moment to honor the liver, the best detox device a body can have. Without prompting, the liver breaks down and dispenses with all sorts of toxic compounds, including alcohol and acetaminophen. Anyone who is truly interested in removing poisons from the body should probably spend less time applying detoxifying pads and potions and more time protecting their liver. One way to give your liver a lift is to avoid bombarding it with too many poisons in the first place.

Scientists at Texas A&M University in College Station unveiled a disease-resistant black Angus bull, saying it could lead to safer beef and more efficient ranching worldwide. The month-old calf, called Bull 86 Squared, was cloned from genetic material frozen 15 years ago from Bull 86.

The conventional idea that most living organisms require two parents has been challenged by Dutch and Czech researchers, who have found a species that has only mothers. They report in the June 29 Science that a species of tropical mite (Brevipalpus phoenicius) consists entirely of females with only one set of genetic material. Most animals have two sets, one from each parent. The male of the mite species is all but nonexistent.

French researchers reported today that they had succeeded in cloning rabbits using genetic material from adult cells. The animal joins sheep, cattle, goats, mice, pigs and cats in the select but rapidly growing fraternity of cloned organisms. The four cloned female rabbits were born last year at the National Institute for Agronomical Research outside Paris.

British scientists have mapped chromosome 20, the third and longest chromosome to be sequenced in the Human Genome Project. Chromosome 20 is best known for harboring genes that contribute to forms of the brain-wasting Creutzfeldt-Jakob disease and severe-combined immunodeficiency, an illness in which the immune system is crippled. Chromosome 20 contains 727 genes and accounts for about 2% of the total human genetic material, the team reported in the Dec. 20 issue of Nature.

Small defects in the male chromosome may be responsible for some cases of infertility, University of Minnesota doctors report in the New England Journal of Medicine. Dr. Jon Pryor and his team found that 7% of the 200 infertile men they studied were missing tiny pieces of their Y chromosomes, genetic material found only in males. However, further study revealed that the deleted pieces did not always cause infertility.

Scientists have confirmed the second case of a "virgin birth" in a shark. In a study reported Friday in the Journal of Fish Biology, scientists said DNA testing showed that a pup carried by an Atlantic blacktip shark at the Virginia Aquarium & Marine Science Center contained no genetic material from a male. In 2007, the female shark died of complications from an unknown pregnancy. Her pup was found during a necropsy. No male blacktips were present in her eight years there.

The Berlin Patient, the only person considered cured of HIV, may soon have some company. Researchers at the International AIDS Conference in Washington, D.C., made presentations Thursday on two HIV-positive men from Boston who developed lymphoma. In both cases, their treatment included a bone marrow transplant, which results in a new immune system. The bone marrow donors did not have HIV. The patients were conditioned for their transplants with a reduced-intensity protocol that allowed them to maintain enough strength to continue taking antiretroviral drugs to keep their HIV in check.
