Tuna Carry Radioactive Contamination From
Japan to U.S.: Study

Bluefin tuna have carried radioactive contamination 6,000 miles from
the waters off Japan to the shores of the United States, according to a
new study.

It’s the first time a large migrating fish has been shown to carry
radioactivity such a distance, the Associated Press reported.

The radioactive cesium comes from Japan’s Fukushima nuclear plant,
which was damaged after the March 2011 earthquake and tsunami. The levels
of the radioactive material found in bluefin tuna off the California coast
were 10 times higher than the amount measured in previous years.

However, the levels are still far below safe-to-eat limits set by U.S.
and Japanese officials, the AP reported.

The study was published online Monday in the journal Proceedings of
the National Academy of Sciences

New Test May Detect Osteoporosis at Early
Stages

A new test that looks for traces of bone calcium in urine could provide
a new way to identify osteoporosis bone loss at the earliest stages, a new
study says.

Currently, osteoporosis can go undiagnosed for years and may only be
detected with scans after a patient suffers a fracture due to the
weakening of bones, BBC News reported.

Arizona State University scientists working with NASA developed the
test. The research was conducted partly astronauts with in mind because
they can suffer bone loss due to the microgravity of space.

Researchers found that the test could detect bone less in healthy
volunteers after as little as one week of bed rest. Prolonged bed rest can
trigger bone loss. The findings were published in the journal
Proceedings of the National Academy of Sciences.

“The next step is to see if it works as expected in patients with
bone-altering diseases. That would open the door to clinical
applications,” said lead researcher Prof Ariel Anbar, BBC News
reported.

Nearly Half of New U.S. Veterans Filing
Disability Claims

About 45 percent of the 1.6 million U.S. veterans of the Iraq and
Afghanistan wars are filing for disability benefits, the highest rate of
any generation of veterans.

Federal government officials say it’s more than double the estimated 21
percent rate of disability claims filed by veterans of the Gulf War in the
early 1990s, the Associated Press reported.

The newest veterans are claiming eight to nine ailments on average,
compared with an average of four for Vietnam veterans and two for veterans
of World War II and the Korean War.

Over the last year, veterans of the Iraq and Afghanistan wars are
claiming 11 to 14 ailments, the AP reported.

So far, disability has been granted to nearly one-third of new veterans
who have applied.

The weak economy, higher wound survival rates, and greater awareness of
problems such as concussions and post-traumatic stress syndrome are among
the factors behind the large increase in veterans’ disability claims, the
AP reported.
