Cultural differences found in pee

Pee from more than 4,000 volunteers shows that people from different nations often have spectacularly different metabolisms.

The finding could point to new ways to deal with obesity, diabetes, high blood pressure and other health problems, researchers said.

After guts break down food and drink, chemicals left in their urine can reveal a lot about peoples' bodies and lifestyles.

Do You Know What Plastic Recycling Symbols Mean?

Do You Know What Plastic Recycling Symbols Mean?

plastic bottleThe Daily Green offers this handy guide on the various types of plastic:

Number 1 Plastics -- PET or PETE (polyethylene terephthalate)
  • Found In: Soft drinks, water and beer bottles; mouthwash bottles; peanut butter containers; salad dressing and vegetable oil containers; ovenable food trays.
  • Recycling: Pick up through most curbside recycling programs.
  • Recycled Into: Polar fleece, fiber, tote bags, furniture, carpet, paneling, straps, (occasionally) new containers
It poses low risk of leaching breakdown products. Recycling rates remain relatively low (around 20 percent), though the material is in high demand by remanufacturers.

Number 2 Plastics -- HDPE (high density polyethylene)
  • Found In: Milk jugs, juice bottles; bleach, detergent and household cleaner bottles; shampoo bottles; some trash and shopping bags; motor oil bottles; butter and yogurt tubs; cereal box liners
  • Recycling: Pick up through most curbside recycling programs, although some only allow those containers with necks.
  • Recycled Into: Laundry detergent bottles, oil bottles, pens, recycling containers, floor tile, drainage pipe, lumber, benches, doghouses, picnic tables, fencing
HDPE carries low risk of leaching and is readily recyclable into many goods.

Formaldehyde Exposure Linked with ALS

Exposure to the widely used chemical formaldehyde may raise one's risk of getting amyotrophic lateral sclerosis (ALS), or Lou Gehrig's disease, U.S. researchers said on Wednesday.

A large study examining a possible association between ALS and 12 types of chemicals turned up the link, which researchers said needs to be confirmed in other studies.

Ovarian cancers may begin in the fallopian tube

NEW YORK (Reuters Health) - New research suggests that fallopian tube cells rather than ovarian surface cells are the probable site of origin of most cases of ovarian serous carcinoma, the most common type of ovarian cancer.

This finding may lead to earlier detection, as well as better treatment and perhaps prevention, of ovarian cancer, Dr. Keren Levanon of the Dana Farber Cancer Institute in Boston told the annual gathering of the American Association for Cancer Research in San Diego.

As there is no early diagnostic test for ovarian cancer, roughly 80 percent of cases are diagnosed at a very late stage. "One fascinating fact," Levanon highlighted, "is that when you diagnose ovarian cancer you find massive invasive tumors on the surface of the ovary -- usually the tumor does not invade the ovary -- but you never find early pre-invasive in situ tumors."

The oldest Americans are also the happiest, research finds

CHICAGO - It turns out the golden years really are golden. Eye-opening new research finds the happiest Americans are the oldest, and older adults are more socially active than the stereotype of the lonely senior suggests. The two go hand-in-hand: Being social can help keep away the blues.

"The good news is that with age comes happiness," said study author Yang Yang, a University of Chicago sociologist. "Life gets better in one's perception as one ages."

A certain amount of distress in old age is inevitable, including aches and pains and the deaths of loved ones and friends. But older people generally have learned to be more content with what they have than younger adults, Yang said.

CDC: Flu season worst in 3 years; vaccine didn't work well

 ATLANTA (AP) - This year's flu season has shaped up to be the worst in three years, partly because the vaccine didn't work well against the viruses that made most people sick, health officials said Thursday.

The 2007-2008 season started slowly, peaked in mid-February and seems to be declining, although cases are still being reported, according to the Centers for Disease Control and Prevention.

Based on adult deaths from flu and pneumonia, this season is the worst since 2003-2004 - another time when the vaccine did not include the exact flu strain responsible for most illnesses.

Each year, health officials - making essentially an educated guess - formulate a vaccine against three viruses they think will be circulating. They guess well most of the time, and the vaccine is often between 70 and 90 percent effective.

But this year, two of the three strains were not good matches and the vaccine was only 44 percent effective, according to a study done in Marshfield, Wis.

Sickened pork workers have new nerve disorder

 

By Julie Steenhuysen

CHICAGO (Reuters) - Eighteen pork plant workers in Minnesota, at least five in Indiana and one in Nebraska have come down with a mysterious neurological condition they appear to have contracted while removing brains from slaughtered pigs, U.S. researchers and health officials said on Wednesday.

They said the illness is a new disorder that causes a range of symptoms, from inflammation of the spinal cord to mild weakness, fatigue, numbness and tingling in the arms and legs.

"As far as we are aware it is a brand new disorder," said Dr. Daniel Lachance of the Mayo Clinic in Rochester, Minnesota, who presented his findings at the American Academy of Neurology meeting in Chicago.

Lachance has been following the 18 Minnesota patients, all of whom have evidence of nerve involvement, typically affecting the legs.

He said tests showed patients had damage to the nerves at the root level near the spinal cord, and at the far reaches of their motor nerves, where the nerves connect with muscle.

U.S. questions plastic baby bottle safety

Phillips Avent Baby Bottles

WASHINGTON - A chemical used to make baby bottles and other shatterproof plastic containers could be linked to a range of hormonal problems, a preliminary government report has found.

The report was greeted by some environmental groups as confirmation of their concerns, while chemical makers latched on to the report’s preliminary nature and its authors’ warning against drawing overly worrisome conclusions.

The federal National Toxicology Program said Tuesday that experiments on rats found precancerous tumors, urinary tract problems and early puberty when the animals were fed or injected with low doses of the plastics chemical bisphenol A.
