The hidden air pollution in our homes

These days, a “very unhealthy” designation for outdoor air is rare. After the passage of the Clean Air Act, in 1963, and the creation of the Environmental Protection Agency, in 1970, the chemical composition of outdoor air became federally regulated, with penalties for polluters. But this victory may be less significant than we assume, because, in … Continue reading The hidden air pollution in our homes

The rise of elective sobriety

Around the country, and especially in certain hipster-ish social circles, sobriety is getting rebranded. Interest in more informal sobriety experiments?—?Dry January, Sober October, One Year No Beer?—?has reached a new peak, with Google Trends reporting that the number of searches for “Dry January” in January 2019 was nearly double what it was two years ago. Is this just … Continue reading The rise of elective sobriety

Is sunscreen the new margarine?

Meanwhile, that big picture just keeps getting more interesting. Vitamin D now looks like the tip of the solar iceberg. Sunlight triggers the release of a number of other important compounds in the body, not only nitric oxide but also serotonin and endorphins. It reduces the risk of prostate, breast, colorectal, and pancreatic cancers. It … Continue reading Is sunscreen the new margarine?

Aging of lab grown human cells successfully reversed by new compounds

Senescent cells are classified as cells that are not older and deteriorated but also compromise the function of cells around them. Studies in animals have shown that the removal of these particular cells can improve some of the effects of aging; including delaying the onset of cataracts.

The loneliest generation: americans, more than ever, are aging alone

The effect of isolation is extraordinarily powerful,” says Donald Berwick, former administrator of the Centers for Medicare and Medicaid Services. “If we want to achieve health for our population, especially vulnerable people, we have to address loneliness.” The Trump administration is looking at expanding faith-based partnerships to combat isolation among seniors, says U.S. Assistant Secretary … Continue reading The loneliest generation: americans, more than ever, are aging alone

DNA researchers pinpoint the type of exercise that could extend life

But perhaps the most well-studied part of anti-aging is the role of telomeres, the protective caps at the ends of chromosomes that naturally get shorter as we get older. As we age, telomeres shorten naturally, but there are some things we can do to slow, or even, in small part, reverse that process. Endurance exercises reversed the shortening of … Continue reading DNA researchers pinpoint the type of exercise that could extend life

The real trick to staying young forever

Relationships deeply affect people’s physical and mental health—including relationships with younger generations. George Vaillant, the psychiatrist who led the study for decades, found that those in middle age or older who invest in nurturing the next generation were three times as likely to be happy as those who fail to do so. “Biology flows downhill,” he … Continue reading The real trick to staying young forever

Is Horvath’s Clock the Smoking Gun of Biological Aging?

Horvath’s clock proved a very clear relationship between this methylation?—?both gained and lost?—?and the chronological age of humans, or as Horvath puts it, “the number on your passport.” He also believes it bears some relationship to biological age, the very definition of which is so hotly debated among biologists that Horvath compares its vagueness to … Continue reading Is Horvath’s Clock the Smoking Gun of Biological Aging?

Forget the blood of teens. This pill promises to extend life for a nickel a pop

Barzilai’s big plan isn’t necessarily less quixotic than those being dreamed up at Silicon Valley biotechs. It’s just quixotic in a completely different way. Rather than trying to develop a wildly expensive, highly speculative therapy that will likely only benefit the billionaire-demigod set, Barzilai wants to convince the FDA to put its seal of approval on … Continue reading Forget the blood of teens.

Is fasting the fountain of youth?

A critical aspect of fasting — which is different from simply restricting calories — is that the body undergoes a metabolic switch from using glucose to using ketones as fuel, a result of the depletion of liver energy stores and the mobilization of fat. The presence of ketones in the blood signifies that on the … Continue reading Is fasting the fountain of youth?
