Teen Drivers’ Marijuana Use Causes
Concern

Teens who drive while high on marijuana appear to be a growing
problem.

Pot smoking is up among teens and use of the drug among high school
students is higher than it has been in three decades, finds new survey
data compiled by Students Against Destructive Decisions (SADD) and the
insurance industry, the Washington Post reported.

Survey results also show that 19 percent of teens said they’d driven a
vehicle while stoned, and more than one-third said marijuana causes no
distractions to their driving, according to the information released
Wednesday.

“What keeps me up at night is that this data reflects a dangerous trend
toward the acceptance of marijuana and other substances compared to our
study of teens conducted just two years ago,” Stephen Wallace, senior
adviser for policy, research and education at SADD, told the
Post.

Last week, the Governors Highway Safety Association said that teen
highway deaths increased in the first half of 2011, reversing an
eight-year downward trend.

Male Y Chromosome Won’t Vanish:
Study

Men’s Y chromosome may not wither away to nothing after all, according
to a new study.

The male Y and female X chromosomes once had about 800 genes in common
but the Y now carries just 19 of its ancestral genes, along with its
male-determining gene, and is just a fraction of its original size, The
New York Times
reported.

This has led some scientists to wonder if the Y chromosome will
eventually vanish and make human males a thing of the past.

But a new study suggests that the Y chromosome’s gene-shedding is
finished and it will shrink no more, The Times reported.

The study was published Wednesday in the journal Nature.

State Can’t Force Pharmacies to Sell Emergency
Contraceptives: Judge

Washington state cannot force pharmacies to sell Plan B or other
emergency contraceptives, a federal judge ruled Wednesday.

State regulations require pharmacies to stock and dispense drugs for
which there is a demand. The regulations were implemented in 2007 after
reports that some women in the state were denied access to Plan B, the
Associated Press reported.

A pharmacy and two pharmacists filed a lawsuit that said the rules
infringed on their religious freedom. U.S. District Judge Ronald Leighton
agreed with them.

The judge ruled that the intent of the state regulations was not to
promote timely access to medicine, but to override religious objections by
pharmacists who believe that emergency contraceptives have an effect
that’s similar to abortion, the AP reported.

U.S. Releases Draft Strategy to Fight
Alzheimer’s Disease

Finding effective ways to treat Alzheimer’s disease by 2025 is the main
goal of the Obama administration’s draft of a national strategy to fight
the disease.

That could be a huge challenge. Current treatments only temporarily
ease symptoms of Alzheimer’s and efforts to develop better medications
have been slow, the Associated Press reported.

The draft also recommends improved training and support for caregivers
of loved ones with Alzheimer’s, campaigns to raise awareness about the
early warning signs of the disease, increased education for doctors and
other health care providers, and improved early detection of
Alzheimer’s.

The draft was released Wednesday and is open for public comment through
March. The final strategy will be released this year, the AP
reported.

More than 5 million Americans have Alzheimer’s or similar dementias and
that number is expected to reach as many as 16 million by 2050.
