Daily Coffee Prevents Disease, Helps You Live Longer
People who drink one to three cups of coffee per day have a lower risk of contracting certain diseases, including dementia, and are more likely to live longer than those who abstain from coffee.
What's the Latest Development?
Several recent health studies confirm that people who drink one to three cups of coffee per day have a lower risk of contracting certain diseases, including dementia, and are more likely to live longer than those who abstain from the caffeinated drink. "In a 2012 study of humans, researchers...tested the blood levels of caffeine in older adults with mild cognitive impairment...and then re-evaluated them two to four years later. Participants with little or no caffeine circulating in their bloodstreams were far more likely to have progressed to full-blown Alzheimer’s than those whose blood indicated they’d had about three cups’ worth of caffeine."
What's the Big Idea?
Dr. Gregory Freund, a professor of pathology at the University of Illinois, believes our species' long love affair with coffee is about more than staying alert. Over the ages, it may have conferred a number of health benefits on those who imbibe it, making it even more popular. Researchers do not understand everything about the effects of coffee, however. It is unclear whether coffee has distinct advantages over simple caffeine, as some studies have suggested. What is clear, say researchers, is that combining caffeine with sugar, such as in energy drinks, confer no health benefits above those of caffeine and coffee.

The pandemic reminds us that our higher education system, with all its flaws, remains a key part of our strategic reserve.
- America's higher education system is under great scrutiny as it adapts to a remote-learning world. These criticisms will only make higher ed more innovative.
- While there are flaws in the system and great challenges ahead, higher education has adapted quickly to allow students to continue learning. John Katzman, CEO of online learning organization Noodle Partners, believes this is cause for optimism not negativity.
- Universities are pillars of scientific research on the COVID-19 frontlines, they bring facts in times of uncertainty and fake news, and, in a bad economy, education is a personal floatation device.
Researchers present what they’ve learned now that they can read the tiny text inside the Antikythera mechanism.
Though it it seemed to be just a corroded lump of some sort when it was found in a shipwreck off the coast of Greece near Antikythera in 1900, in 1902 archaeologist Valerios Stais, looking at the gear embedded in it, guessed that what we now call the “Antikythera mechanism" was some kind of astronomy-based clock. He was in the minority—most agreed that something so sophisticated must have entered the wreck long after its other 2,000-year-old artifacts. Nothing like it was believed to have existed until 1,500 years later.
The institutional barriers that have often held creative teaching back are being knocked down by the coronavirus era.
- Long-held structures in the education system, like classroom confines and schedules, have held back innovation for a long time, says education leader Richard Culatta.
- In the coronavirus era, we have been able to shake some of those rigid structures loose, making way for creativity and, ultimately, a more open mindset.
- When creativity and technology combine, learning can become so much more than delivering content to a student. Culatta gives two stunning examples: one of a biotech class, and another involving a student discovering a star.
We'd like to think that judging people's worth based on the shape of their head is a practice that's behind us.
'Phrenology' has an old-fashioned ring to it. It sounds like it belongs in a history book, filed somewhere between bloodletting and velocipedes.
Maybe you've been wondering if you're seeing one persistent squirrel or a rotating cast of characters.
