At 112, N.Y. Man Is World's Oldest: Guinness
A 112-year-old man in western New York is now the oldest man in the world, according to Guinness World Records.
Salustiano Sanchez-Blazquez, who took the title when Jiroemon Kimura died June 12 at age 116, credits his longevity to eating a banana a day and a daily dose of six Anacin tablets, the Associated Press reported.
The world's oldest person is a woman, 115-year-old Misao Okawa of Japan.
Salustiano was born in Spain on June 8, 1901 and came to the United States in 1920. He worked in coal mines in Kentucky and then moved to the Niagara Falls area of New York, with jobs in construction and in the industrial furnaces. He married his wife, Pearl, in 1934, the AP reported.
Salustiano -- whose nickname is "Shorty" -- said he was humbled by the attention and that he didn't feel he accomplished anything special just because he has lived longer than most, according to a statement released by Guinness World Records.
Groundbreaking Sex Researcher Virginia Johnson Dies
Pioneering sex researcher Virginia Johnson died Wednesday at age 88.
She and William Masters revolutionized the study of sex in the 1960s and wrote two best-sellers on the topic, "Human Sexual Response" and "Human Sexual Inadequacy," the Associated Press reported.
For the next 20 years, Masters and Johnson were celebrities. They married in 1971 and divorced 20 years later. Masters died in 2001.
Johnson died at an assisted living facility in St. Louis after suffering complications from various illnesses, according to her son, Scott Johnson. A private funeral is planned, the AP reported.
Luxury Cruise Ship Fails Surprise CDC Inspection
The luxury cruise ship Silver Shadow failed a surprise inspection by U.S. health officials and was cited for attempting to move 15 trolleys of food from the galley to individual crew cabins to avoid inspection.
The snap inspection by the Centers for Disease Control and Prevention was conducted June 17 in Skagway, Alaska after an anonymous crew member sent photos to the CDC showing meat in crew cabin sinks and trays of food in the corridors in the passageways outside of those cabins, CNN reported.
The ship, owned by Silversea Cruises, was given a failing grade of 82. Anything less than 84 is considered "less than satisfactory," according to the CDC's Vessel Sanitation Program website.
In its ads, Florida-based Silversea Cruises emphasizes luxury and what it claims is a "world class" culinary experience. Passengers pay an average of $5,000 a week to sail, CNN reported.
Silversea vessels have always scored in the highest range of grades in the past and these inspection results on the Silver Shadow were an anomaly, company spokeswoman Gina Finocchiaro told CNN. Neither she or anyone else at Silversea would divulge whether any employees were disciplined over the inspection findings.
Don't Change Medicare Payment System: Panel
Changing the Medicare payment system to reward hospitals and doctors in areas of the country that provide high-quality care at low cost is not a good idea, according to the Institute of Medicine at the National Academy of Sciences.
The conclusion by a 19-member panel after a three-year study challenges statements by members of Congress from states such as Iowa and Minnesota who claim that Medicare has shortchanged their health care providers for decades, The New York Times reported.
The panel said Congress should not create a "value index" to channel Medicare funds to regions that provide high-quality health services at relatively low cost. They said this would be unfair because it would "reward inefficient providers in low-cost regions and punish more efficient providers in high-cost regions."
The panel explained that a regional value index makes no sense because spending for doctors and hospitals in a single area often vary as much as spending for health care providers in different regions, The Times reported.
Cat Allergy Trigger Identified
Scientists who discovered what triggers allergic reactions to cats say their findings could lead to new treatments for the problem.
The team at the University of Cambridge in the U.K. pinpointed how the body's immune system detects cat allergen, resulting in symptoms such as sneezing and coughing, BBC News reported.
The findings, published in the Journal of Immunology, are a major step forward in understanding how cat allergen causes allergic reactions, said the charity group Allergy U.K.
"Cat allergen is particularly difficult to avoid as it is a 'sticky' molecule that is carried into every building on people's shoes and clothes," Maureen Jenkins, the group's director of clinical services, told BBC News. "It can also still be found in a home, on the walls and ceiling or fittings, even a few years after a cat has ceased to live there."
She said these findings "could pave the way for treatments for those with persistent disease triggered by cat allergen and, in the future, potentially dog and house dust mite allergen."
High Lead Levels Found in Some Mexican
High levels of lead have been found in four Mexican salsa brands that are sold in some areas of the United States.
The brands include El Pato Salsa Picante, Salsa Habanera, Salsa Picante de Chile Habanero and Bufalo Salsa Clasica, said researchers at the University of Nevada, Las Vegas, ABC News/Univision reported.
The U.S. Food and Drug Administration does not have an established safe level of lead in hot sauces, according to the researchers. But they said that these four brands of salsa had lead levels exceeding 0.1 parts per million, which is the current FDA standard for safe lead levels in candy.
The researchers noted that hot sauces from Mexico contain similar ingredients to spicy candies that are made in that country and also sold at ethnic food stores throughout the U.S., ABC News/Univision reported.
The good news is that the UNLV team analyzed 25 brands of imported hot sauces and only found lead problems in these four brands.
