Faulty breast implants made by PIP, the French company that sparked a global health scare, do not pose any long-term medical threats, British health authorities said in a final report Monday.

The silicone gel filler used inside the implants is not toxic and does not increase the risk of breast cancer, the National Health Service's (NHS) Medical Directors group said.

U.S. luggage maker Samsonite said Monday it had withdrawn some of its suitcases from Hong Kong stores after a consumer group found they contained high levels of chemicals that may cause cancer.

The company said its Tokyo Chic brand had been taken off the shelves even though its own tests indicated there was no threat to consumers from the Polycyclic Aromatic Hydrocarbons (PAH) in the side-carrying handles.

Fewer motorcyclists die in states that require helmets, and the costs to society are lower too, according to a new federal study released Thursday.

About five times as many no-helmet biker deaths occur in states with less restrictive laws, the Centers for Disease Control and Prevention study found.

The first vaccine that protects children as young as six weeks against two potentially deadly bacterial infections has won approval from U.S. health regulators.

They live on your skin, up your nose, in your gut — enough bacteria, fungi and other microbes that collected together could weigh, amazingly, a few pounds.

Now scientists have mapped just which critters normally live in or on us and where, calculating that healthy people can share their bodies with more than 10,000 species of microbes.

An American man whose HIV seemed to disappear after a blood marrow transplant for leukemia may be showing new hints of the disease, sparking debate over whether a cure was really achieved.

Scientists disagree over the latest findings on Timothy Brown, also known as the "Berlin patient," presented at a conference in Spain last week, according to a report in the journal Science's ScienceInsider blog.

Surgeons said Thursday they had transplanted the first-ever vein grown in a lab from a patient's own stem cells into a 10-year-old girl, sparing her the trauma of harvesting veins from her body.

The groundbreaking procedure may offer hope for patients who don't have healthy veins for use in dialysis or heart bypass surgery, said a paper published in the Lancet medical journal.

An influential British bioethics group says that couples who face the risk of having a baby with certain genetic diseases should be allowed to use eggs from two women to produce the embryo.

Such controversial procedures should only be allowed if they are proven safe, the Nuffield Council on Bioethics said Tuesday, but its advice seems likely to reignite debate. Currently, such treatments are only allowed for research in the U.K., and British law forbids altering a human egg or embryo before transferring it into a woman.
