Wax inside a whale’s ear stores all sorts of useful information on the animal’s exposure to pollutants and stress levels throughout life, researchers have found.
The team, led by Sascha Usenko, a environmental scientist at Baylor University in Waco, Texas, extracted an earplug from a blue whale (Balaenoptera musculus) killed in a collision with a ship off the coast of Santa Barbara, California, in 2007 and found it had come into contact with several organic pollutants and contained high levels of the stress hormone cortisol as it reached sexual maturity.
Decimated by historic whaling practices, blue whales number just 5,000–12,000 individuals worldwide, and they are threatened by entanglement in fishing nets, environmental noise and pollution. Maternal transfer of pollutants is known to happen in other mammals, such as seals and humans.
Usenko and his team are now hoping to investigate that question by analysing some of the 1,000 or more whale specimens in museums worldwide.
A Humpback whale jumps in the surface of the Pacific Ocean at the Uramba Bahia Malaga natural park in Colombia, on July 16, 2013. Gastroesophageal reflux, often referred to as GERD, occurs when acid from the stomach backs up into the esophagus. When stomach acid touches the sensitive tissue lining the esophagus and throat, it causes a reaction similar to squirting lemon juice in your eye. During gastroesophageal reflux, the acidic stomach contents may reflux all the way up the esophagus, beyond the upper esophageal sphincter (a ring of muscle at the top of the esophagus), and into the back of the throat and possibly the back of the nasal airway. In infants and children, LPR may cause breathing problems such as: cough, hoarseness, stridor (noisy breathing), croup, asthma, sleep disordered breathing, feeding difficulty (spitting up), turning blue (cyanosis), aspiration, pauses in breathing (apnea), apparent life threatening event (ALTE), and even a severe deficiency in growth. The symptoms of GERD may include persistent heartburn, acid regurgitation, nausea, hoarseness in the morning, or trouble swallowing. If you experience any symptoms on a regular basis (twice a week or more) then you may have GERD or LPR. Unfortunately, GERD and LPR are often overlooked in infants and children leading to repeated vomiting, coughing in GER and airway and respiratory problems in LPR such as sore throat and ear infections.
A gastroenterologist, a specialist in treating gastrointestinal orders, will often provide initial treatment for GERD.
Your primary care physician or pediatrician will often refer a case of LPR to an otolaryngologist—head and neck surgeon for evaluation, diagnosis, and treatment. In adults, GERD can be diagnosed or evaluated by a physical examination and the patient’s response to a trial of treatment with medication.
Symptoms of GERD or LPR in children should be discussed with your pediatrician for a possible referral to a specialist. Most people with GERD respond favorably to a combination of lifestyle changes and medication.
Children and adults who fail medical treatment or have anatomical abnormalities may require surgical intervention. Audiology is simply another term used in studies related to hearing, balance, and disorders related to this. It is a simple test procedure measuring your hearing ability through a range of frequency. In some cases further testing may be recommended to rule out involvement of other medical problems associated with hearing loss.

Musicians ear plugs are flat-response attenuators which replicate the natural response of the open ear, so that sound heard through these plugs has the same quality as the original sound, just quieter. Musicians Earplugs attenuate sound across all frequencies rather than just low and mid-range frequencies, making music more clear natural sounding. Suitable for use under light noise exposure such as vocalists and acoustic guitar or strings players. It’s essential to protect your hearing, especially if you spend a lot of time in noisy environments.

Scientists have long used whale blubber as a record of the chemicals that these enormous creatures absorb as they traverse the ocean. But it also records time — similarly to the rings of a tree, the wax is laid down in light and dark bands, with each band correlating roughly to a six-month period. During his brief life he came into contact with 16 persistent organic pollutants, including pesticides and flame retardants. The peak was directly after the whale reached sexual maturity, at about ten years old, suggesting stress from sexual competition. Humpback whales (Megaptera novaeangliae) migrate annually from the Antarctic Peninsula to peek into the Colombian Pacific Ocean coast, with an approximate distance of 8,500 km, to give birth and nurse their young.
Almost all individuals have experienced reflux (GER), but the disease (GERD) occurs when reflux happens on a frequent basis often over a long period of time. For proper diagnosis and treatment, you should be evaluated by your primary care doctor for GERD or an otolaryngologist—head and neck surgeon (ENT doctor). Most infants grow out of GERD or LPR by the end of their first year; however, the problems that resulted from the GERD or LPR may persist. But there are ear, nose, and throat problems that are either caused by or associated with GERD, such as hoarseness, laryngeal (singers) nodules, croup, airway stenosis (narrowing), swallowing difficulties, throat pain, and sinus infections. Other tests that may be needed include an endoscopic examination (a long tube with a camera inserted into the nose, throat, windpipe, or esophagus), biopsy, x-ray, examination of the throat and larynx, 24 hour pH probe, acid reflux testing, esophageal motility testing (manometry), emptying studies of the stomach, and esophageal acid perfusion (Bernstein test).
Such treatment includes fundoplication, a procedure where a part of the stomach is wrapped around the lower esophagus to tighten the LES, and endoscopy, where hand stitches or a laser is used to make the LES tighter. The hearing sense organ in the inner ear then sends the signals to the brain via the hearing nerves. The goal of the visit is to help you understand hearing loss and what it means to you and how it effects your everyday listening in quiet and more demanding situations. Alice Wilson is our Board Certified audiologist with 27 years of experience by the American Board of Audiology, (ABA), a Fellow of the American Academy of Audiology, (F-AAA), is licensed in audiology and hearing aids in Virginia and the District of Columbia, and holds a current Certificate of Clinical Competence in Audiology, (CCC-A), from the American Speech Hearing and Language Association, (ASHA), and was awarded the Audiology Scholarship Award by the American Academy of Audiology.
The tests will involve moving the head and body into different positions, as well as stimulating both ears with cool and warm air.

In baleen, or filter-feeding, whales, earwax forms a solid plug that may be tens of centimetres long and remains intact even after its death. Exposure to the most persistent chemicals was greatest in the first year — and accounted for one-fifth of his total lifetime contact — suggesting a transfer of contaminants from his mother in the womb and during nursing. But it is unclear whether the overall increase was caused by natural events, such as weaning, or by human activities, such as pollution and noise.
Instead, they experience pain in the chest that can be severe enough to mimic the pain of a heart attack. Physical causes can include a malfunctioning or abnormal lower esophageal sphincter muscle (LES), hiatal hernia, abnormal esophageal contractions, and slow emptying of the stomach. These problems require an otolaryngologist—head and neck surgeon, or a specialist who has extensive experience with the tools that diagnose GERD and LPR. Endoscopic examination, biopsy, and x-ray may be performed as an outpatient or in a hospital setting.

In those who have GERD, the LES does not close properly, allowing acid to move up the esophagus.
Lifestyle factors include diet (chocolate, citrus, fatty foods, spices), destructive habits (overeating, alcohol and tobacco abuse) and even pregnancy. Endoscopic examinations can often be performed in your ENT’s office, or may require some form of sedation and occasionally anesthesia.

Mercury — which can cause brain damage — spiked twice in the sample, at around five and ten years. Some people with LPR may feel as if they have food stuck in their throat, a bitter taste in the mouth on waking, or difficulty breathing although uncommon. Young children experience GERD and LPR due to the developmental immaturity of both the upper and lower esophageal sphincters. That's right, our bodies need to breath but too much of a good thing is making us sick, fat and fatigued. Foundation also protects your skin from all the free radicals we are exposed to in the air. Grape seed extract is beneficial for a wide variety of health concerns, such as high blood pressure and diabetes, but it also stands out as a cancer fighter, particularly for cancers that are aggressive and difficult to treat, such as treat triple negative breast cancer.
