People with obesity, high blood sugar, high blood pressure or high cholesterol are often advised to eat less and move more, but our new research suggests there is now another simple tool to fight off these diseases: restricting your eating time to a daily 10-hour window.
Debaucherous evening last night? You’re probably dealing with veisalgia right now.
More commonly known as a hangover, this unpleasant phenomenon has been dogging humanity since our ancestors first happened upon fermentation.
Those nasty vertigo-inducing, cold sweat-promoting and vomit-producing sensations after a raucous night out are all part of your body’s attempt to protect itself from injury after you overindulge in alcoholic beverages. Your liver is working to break down the alcohol you consumed so your kidneys can clear it out ASAP. But in the process, your body’s inflammatory and metabolic reactions are going to lay you low with a hangover.
Working overtime to clear out the booze
Hangovers are virtually guaranteed when you drink too much. That amount varies from person to person based on genetic factors as well as whether there are other compounds that formed along with ethanol in the fermentation process.
Over the course of a night of heavy drinking, your blood alcohol level continues to rise. Your body labors to break down the alcohol – consumed as ethanol in beer, wine or spirits – forming damaging oxygen free radicals and acetaldehyde, itself a harmful compound. The longer ethanol and acetaldehyde stick around, the more damage they can do to your cellular membranes, proteins and DNA, so your body’s enzymes work quickly to metabolize acetaldehyde to a less toxic compound, acetate.
The rise of wearable fitness trackers has increased the number of people monitoring their heart rate, both throughout the day and during exercise.
Whether you’re an athlete trying to gain the competitive edge, a weekend warrior tracking progress or someone who is just trying to improve your health, consider heart rate a valuable tool in understanding the work of your amazing body as it achieves those first steps, that next 5K or even Olympic gold.
Even with the progress made in introducing alternatives to fossil fuels, gaining energy efficiencies and proposed carbon regulations around the world, avoiding catastrophic impacts on our coastal infrastructure, biodiversity, food, energy and water resources will require more. In particular, many climate researchers like myself believe government needs to advance technology that will actually suck carbon dioxide out of the air and put it away for very long periods.

NASA’s next Mars rover has passed its first driving test. A preliminary assessment of its activities on Dec. 17, 2019, found that the rover checked all the necessary boxes as it rolled forward and backward and pirouetted in a clean room at NASA’s Jet Propulsion Laboratory in Pasadena, California. The next time the Mars 2020 rover drives, it will be rolling over Martian soil.
The Centers for Disease Control and Prevention recently announced a preliminary finding that implicates a vitamin E additive as the potential cause of lung injury from THC vaping.
The agency examined fluid samples from the lungs of 29 patients with vaping-related illness and found vitamin E acetate in all 29 samples. This is a major development in the search for answers, and it was of great interest to me generally as a public health researcher.

A little robotic explorer will be rolling into Antarctica this month to perform a gymnastic feat – driving upside down under sea ice.
BRUIE, or the Buoyant Rover for Under-Ice Exploration, is being developed for underwater exploration in extraterrestrial, icy waters by engineers at NASA’s Jet Propulsion Laboratory in Pasadena, California. It will spend the next month testing its endurance at Australia’s Casey research station in Antarctica, in preparation for a mission that could one day search for life in ocean worlds beyond Earth.
Migraine is not just a headache but also includes a collection of associated symptoms that can be debilitating. These include nausea, vomiting, light sensitivity and dizziness. Often people struggle to determine what triggers their migraines. It can be environmental, hormonal, genetic, secondary to an underlying illness, or triggered by certain foods, such as cheese, red wine or chocolate. One food that has received a lot of attention in recent years is gluten – a protein found in wheat, rye and barley.
Ask people what they know about Antarctica and they usually mention cold, snow and ice. In fact, there’s so much ice on Antarctica that if it all melted into the ocean, average sea level around the entire world would rise about 200 feet, roughly the height of a 20-story building.
Could this happen? There’s evidence that at various times in the past there was much less ice on Antarctica than there is today. For example, during an extended warm period called the Eemian interglacial about 100,000 years ago, Antarctica probably lost enough ice to raise sea level by several meters.
Living in rural America certainly comes with a number of benefits. There is less crime, access to the outdoors, and lower costs of living.
Yet, not everything is rosy outside the city limits. Rural communities face growing infrastructure problems like decaying water systems. And they have more limited access to amenities ranging from grocery stores to movie theaters, lower quality schools, and less access to high-speed internet.
