WHO Expert Panel Cites Diesel Exhaust as
Carcinogen
Diesel exhaust causes cancer, the International Agency for Research on
Cancer (IARC) said in a ruling released Tuesday after a weeklong
discussion.
The agency, a part of the World Health Organization, said its decision
means that diesel exhaust could be ranked as important a public health
threat as secondhand smoke, CBS News and the Associated
Press reported.
The risk of developing cancer from diesel fumes is small but so many
people breathe in the fumes that boosting the status of diesel exhaust
from probable carcinogen to carcinogen was an important change, said the
agency.
“It’s on the same order of magnitude as passive smoking,” said IARC
Director Kurt Straif, CBS/AP reported. “This could be another big
push for countries to clean up exhaust from diesel engines.”

Bioethics Council Backs Use of Eggs from Two
Women to Create Embryo
Couples at risk of having a baby with certain genetic diseases should
be allowed to use eggs from the mother and another woman to produce a
healthy embryo, but only if such procedures are proven safe, an
influential British bioethics group said in a report released Tuesday.
“If these novel techniques are adequately proven to be acceptably safe
and effective as treatments, it would be ethical for families to use
them,” according to the Nuffield Council on Bioethics, the Associated
Press reported.
In 2008, British scientists were the first to announce that they had
created embryos using eggs from two women and sperm from one man.
Currently, this technique is only allowed for research in the U.K.
The bioethics council said it would likely take several years for
researchers to prove that this method is effective and safe, the AP
reported.

Proposed NYC Ban on Large Sugary Drinks Goes
to Health Board
A proposal to ban large sugary drinks from New York City eateries is
scheduled to be formally submitted to the city’s board of health Tuesday,
even though a new poll finds that about half of New Yorkers think the ban
goes too far.
The board is expected to hold a series of public meetings during a
90-day comment period on the proposed rule, which Mayor Michael Bloomberg
says is needed in order to fight the rise in obesity deaths, the
Associated Press reported.
The ban would apply only to sweetened drinks over 16 ounces that
contain more than 25 calories per 8 ounces. It would not apply to diet
soda or any other calorie-free drinks.
It’s the first time a city has proposed such a measure, the AP
reported.

Study Findings Could Improve Cervical Cancer
Prevention
Researchers say their finding about where and how cervical cancer
begins could lead to better prevention of the disease.
The team discovered that most cases of cervical cancer are triggered
when human papillomavirus infects a specific population of stem-like cells
located near the opening of the cervix, Agence France-Presse
reported.
The study was published in the journal Proceedings of the National
Academy of Sciences.
Each year, nearly 530,000 women worldwide are diagnosed with cervical
cancer and 275,000 die from the disease, according to the World Health
Organization, AFP reported.

Gay Parenting Study Generates
Controversy
Controversy is swirling around a study that found that young adults
from broken homes in which a parent had a same-sex relationship had
slightly more mental health and social problems than others from homes
fragmented by divorce and other problems.
Participants’s parents were classified as gay or lesbian if they had
ever had a same-sex relationship, even if the parents did not identify
themselves as gay or lesbian, The New York Times reported.
The study, which was funded by conservative foundations and published
Sunday in the journal Social Science Research, was attacked by
gay-rights groups as being biased and poorly done.
However, many outside experts said the study was rigorous and provides
some of the best data yet comparing outcomes among adult children with a
gay parent and those with a heterosexual parent, The Times
reported.
However, the experts also said the findings are not particularly
relevant to the ongoing debate over gay marriage or gay
parenting.
