Whales record major life events in their earwax

Who needs a diary when you’ve got whale earwax? Hormone peaks, ocean pollutants, stress levels – it’s all there.

The plugs, which can weigh 250 grams and be 25 centimetres long, reflect annual migration patterns. During a blue whale’s six-month feeding season, earwax is light-coloured, filled with fat from its rich diet. As it fasts during migration, a darker layer forms. These layers allow scientists to age whales when they’re found dead.

Now, for the first time researchers have used the earwax to study a whale’s exposure to ocean contaminants from birth to death. “This has opened the floodgates for doing some great analysis,” says Sascha Usenko of Baylor University, Waco, Texas. “Now we can look at the impact of ocean contaminants on these organisms historically, which has always been very hard to address.”

Usenko and Stephen Trumble, also at Baylor University, shaved away at a plug from a 12-year-old male blue whale that was killed in a 2007 boating accident off the coast of California. The layers contained varying concentrations of DDT and flame-retardants. Exposure was highest during its first year, probably while the whale was nursing.

The plug also contained traces of hormones, which are broken down by the body and don’t leave records elsewhere. Testosterone levels peaked at 10 years, marking the beginning of sexual maturity, which can be difficult to determine but is important for conservation efforts. And levels of the stress hormone cortisol increased over the whale’s life, possibly because finding food, migrating and mating all got harder.

Usenko says the earwax method means we can look at how exposure to chemicals in the environment alters a whale’s stress levels, and how exposure today is different from exposure say, 50 years ago.

New Policy for NIOSH/PFT Refresher Students

Effective immediately, all NIOSH/PFT refresher students must bring their current NIOSH approved Spirometry course certificates to the refresher course.

New Program Change: 7-Month Grace Period for Certificates

NIOSH-Approved Spirometry course certificates currently expire 5 years after the course is completed.  To renew their official NIOSH course certificates, technicians should complete a NIOSH-Approved Spirometry Refresher course before their current course certificate expires.

However, since NIOSH-Approved Spirometry Refresher Courses may not always be available at the specific time needed, NIOSH is instituting a 7-month grace period to extend the window of time for completing the needed NIOSH-Approved Refresher training.

For example, if the current certificate was awarded on April 1, 2008, then the technician may take a NIOSH-Approved Spirometry Refresher Course within 5 years and 7 months of that date, i.e., until November 1, 2013.

See here for our list of course dates for the remainder of 2013 and the full 2014 schedule.


Come see us at these trade shows!

Workplace Integra will be at the following trade shows for the remainder of 2013:

Asbestos: Toxic Fibers that Can Lead to Cancer

Source: Mesothelioma Center at Asbestos.com

When discussing workplace health concerns, it’s impossible to leave asbestos out of the conversation. While occupational health experts acknowledge it as a human carcinogen, more than 120 million people worldwide still come into contact with the fibers at their work sites.

In the past, thousands of manufacturers added the fibers to their commercial and industrial products. Because asbestos was inexpensive, easy to acquire and highly durable, it was used in everything from insulation to roofing products.

Asbestos industry workers who made these products from raw materials handled the loose fibers every day, and workplace exposure was inevitable. But employees who used asbestos products in their finished form also faced occupational health hazards. More than 75 occupational groups – many of them in the blue-collar sector – have used the fibers in some way.

Occupations with a strong exposure history include:

• Auto mechanics

• Factory workers

• Boiler room workers

• Power plant workers

• Blacksmiths

• Insulators

Workers in jobs like these often handled asbestos on a daily basis. Once they inhaled or ingested the fibers, their risk for illnesses like mesothelioma of the peritoneum and lung cancer drastically increased. The World Health Organization estimates that more than 107,000 people die each year from asbestos-related illnesses.

Current Asbestos Hazards in the Workplace

While we expect to see these rates decrease as occupational health measures increase, workplace exposure hazards still exist. Asbestos products are more tightly regulated than they were in the past, but they’re not officially banned in the United States.

Old asbestos products that have been in place for the last 20 to 30 years pose the majority of workplace exposure threats. Construction, demolition and home renovation workers can encounter the fibers as they pull out and replace old asbestos-containing materials. Firefighters face a similar risk as they respond to calls in older buildings; the flames can damage asbestos products to the point that the fibers enter the air.

To avoid inhaling airborne asbestos, it’s important for workers to wear appropriate respiratory protection when they work in potentially contaminated areas. Full-face respirators and additional body coverings are essential in keeping the microscopic fibers out of the body.

Workers must also keep their contaminated clothing away from their off-duty clothes. It’s crucial to wash the clothes at work, in a specially designated machine, to help avoid bringing the carcinogenic fibers away from the jobsite.

Lastly – but certainly not least – workers should never accept jobs that require them to handle asbestos if they don’t hold an up-to-date asbestos certification. State-accredited programs provide essential guidance in identifying, handling and properly disposing of asbestos materials that pose occupational health threats.

Deaf boy with auditory brain stem implant stunned after hearing dad for first time

By: Michelle Castillo/CBS News/June 20, 2013, 12:17 PM

A 3-year-old boy is hearing the world for the first time, thanks to an auditory brain stem implant.

“He likes sound,” young Grayson’s mom Nicole Clamp, said to CBS affiliate WBTV in Charlotte, N.C. “He enjoys the stimulus, the input. He’s curious, and he definitely enjoys it.”

Grayson Clamp was born without his cochlear nerves, or the auditory nerve that carries the sound signal from the cochlea in the inner ear to the brain. His parents tried giving him a cochlear implant, but it did not work.

They then enrolled Grayson in a research trial at University of North Carolina Hospitals in Chapel Hill, N.C. Three weeks ago, he became the first child in the U.S. to receive an auditory brain stem implant.

The procedure involves placing a microchip on the brain stem to bypass the cochlear nerves altogether. The person perceives and processes sound, which travel through tubes in his ear.
