DES MOINES, Iowa — Longtime Rep. Steve King has been ousted in Iowa’s Republican primary after being ostracized by party leaders for comments about white nationalism. State Sen. Randy Feenstra won the five-way race Tuesday after he argued the nine-term conservative Republican had cost the district a voice in Congress by losing his committee assignments over comments in a 2018 New York Times story that seemed to defend white nationalism. King has a long record of incendiary comments about immigrants and white supremacy. Feenstra becomes the heavy favorite to win in the district, where registered Republicans outnumber Democrats by roughly 60,000. He faces Democrat J.D. Schoulten, who lost by 2 percentage points to King in 2018. 748

Eleven people have died so far in 2019 while climbing Mount Everest, a behemoth of a mountain that towers 29, 029 feet above sea level. This is more than twice the number of people who died climbing Everest in 2018, which saw only five deaths that season.But it's not the number of deaths that some may find shocking — it's the reasons behind them. Only two of this season's Mount Everest deaths can be attributed to falls.So what's killing climbers ascending the mountain? It's primarily exhaustion and altitude sickness, and something called "the death zone."Seasoned climbers call any part of the mountain above 26,000 feet "the death zone" because there is only so long a human can survive at that elevation due to lack of oxygen. "Even when using bottled oxygen, supplemental oxygen, there's only a very few number of hours that we can actually survive up there before our bodies start to shut down," mountain guide Adrian Ballinger told CNN. And, unfortunately, the wait at the summit of Mount Everest plays a role in these deaths because the longer someone is at that altitude, the more severe they feel the effects from lack of oxygen and exhaustion. During the week beginning May 20, crowds of climbers became stuck in a queue to the summit. When this happens, climbers aren't eating, drinking or sleeping and continue to use up vital oxygen, which can lead to death.British climber Robin Haynes Fisher was one of those who had warned of the dangers of overcrowding."With a single route to the summit, delays caused by overcrowding could prove fatal so I am hopeful my decision to go for the 25th will mean fewer people. Unless of course everyone else plays the same waiting game," he wrote in a captioned Instagram post on May 19.He died after suffering from what appeared to be altitude sickness at 28,215 feet, while returning from the summit on Saturday.Altitude sickness occurs when people are at high elevations for an extended period of time. It can happen anywhere that's 8,000 feet above sea level or more. There are three types of altitude sickness. From least to most severe, they are: acute mountain sickness, high-altitude pulmonary edema (HAPE) and high-altitude cerebral edema (HACE). The symptoms for all three types are similar (headache, fatigue, dizziness, nausea, vomiting, shortness of breath), but HAPE is accompanied by a buildup of fluid in the lungs and HACE, the most severe type of altitude sickness, occurs when there's a buildup of fluid in the brain.So how can climbers avoid the same deadly fate as the 11 who died? Simply put — be careful. Acclimate as slowly as you can to increased elevations, drinks tons of water, rest and immediately start descending if you feel symptoms of altitude sickness.CNN contributed to this story. 2782

Eating a diet of French fries, Pringles and white bread was enough to make one teenage boy lose his sight, according to a case study published in a medical journal.Scientists from the University of Bristol examined the case of a young patient whose extremely picky eating led to blindness, and have warned of the dangers of a poor diet.The unidentified patient told doctors he had only eaten fries from the fish and chip shop, Pringles potato chips, white bread, slices of processed ham and sausage since elementary school, and he avoided foods with certain textures. He first visited a doctor at age 14, complaining of tiredness, according to a case report published in the Annals of Internal Medicine on Monday.He wasn't taking any medication, had a normal BMI and height, and showed no visible signs of malnutrition.Doctors discovered low vitamin B12 levels and anemia, treating the patient with vitamin B12 injections and offering dietary advice.One year later there were signs of hearing loss and vision symptoms, but doctors did not find the cause.His vision had worsened to the point of blindness by 17 years of age, and doctors identified vitamin B12 deficiency, low copper and selenium levels, a high zinc level, reduced vitamin D level and bone level density, according to a 1297

DENVER, Colo. — On a clear October day in 1970, travelers were making their way along Loveland Pass. At about 11,900-foot elevation, most wouldn't expect to see an airliner flying in the valley below. But eyewitnesses at that elevated location 256
