Mercury Found in Skin-Lightening
Cream

Mercury has been found in illegal Mexican-made skin-lightening cream
being sold in California.

Health investigators are teaming with health and beauty workers in the
immigrant communities of Oakland, San Francisco and San Jose to track down
the skin cream in shops and at swap meets. Officials are also urging
consumers to dispose of the products safely, the Associated Press
reported.

Earlier this month, the California Department of Public Health issued a
medical alert to health care professionals asking them to notify the state
of potential mercury poisoning cases and to tell their patients to stop
using the cream.

Skin lightening cream is typically used to lighten skin, reduce
freckles and age spots, and treat acne, the AP reported.

Radiation From Nuclear Plant Detected Far Off
Japan’s Coast

Water samples collected from the Pacific Ocean in June 2011 showed that
radioactive contamination from the damaged Fukushima nuclear power plant
was present up to nearly 400 miles off the Japanese coast, scientists
say.

Some of the water samples showed readings for cesium-137 up to 1,000
times higher than prior levels, but those elevated levels are far below
what is generally considered harmful to marine animals or people who eat
seafood, according to Ken Buesseler of the Woods Hole Oceanographic
Institution in Massachusetts, the Associated Press reported.

Along with the thousands of water samples collected about three months
after the nuclear power plant disaster, researchers also tested fish and
plankton and found cesium-137 levels well below the legal limit, Buesseler
said Tuesday at the annual Ocean Sciences Meeting in Salt Lake City.

He was chief scientist for the cruise that took water samples from
about 20 miles to 400 miles off the coast east of the Fukushima plant.
Buesseler said concentrations of cesium-137 ranged from 10 to 1,000 times
higher than normal, but were about 10 percent of the levels generally
considered harmful, the AP reported.

Because swirling ocean currents created concentrations of cesium-137,
the highest readings were not always from water samples taken closest to
the plant, Buesseler explained. He also noted that most of the cesium-137
in the ocean came from water discharges, rather than atmospheric
fallout.

Cesium-137 wasn’t the only type of radioactive contamination released
from the Fukushima plant, but is of particular concern because of its long
persistence in the environment, Buesseler said.

Due to continued leakage from the plant, Buesseler told the AP
that “we’re not over the hump” yet in terms of radioactive contamination
of the ocean.

Stem Cell Transplant Helps Monkeys with
Parkinson’s Disease

Monkeys with Parkinson’s disease showed significant improvements in
movement after human embryonic stem cells were implanted in their brains,
according to Japanese scientists.

Before the procedure, the four monkeys all had violent shaking in their
limbs and were unable to control their bodies, Agence France-Presse
reported.

Three months after the stem cell transplant, the monkeys began showing
recovery of their muscle control. Within about six months, they were able
to walk around in their cages.

“Clear improvements were confirmed in their movement,” Jun Takahashi,
an associate professor at Kyoto University, told AFP.

He said these results are a world first and he wants to make the
procedure more safe and effective before conducting human clinical
trials.
