Coffee and Cigarettes: New Study Reveals an Unexpected Connection



Some smokers discover that going without a cup of coffee makes their first cigarette of the day less enjoyable. But it's possible that this is not only a morning habit. Researchers from the University of Florida claim that substances found in roasted coffee beans may help lower the severity of morning cravings for nicotine.

In a cell-based investigation, scientists discovered two components in coffee that have a direct impact on specific high-sensitivity nicotine receptors in the brain. After a night of nicotine withdrawal, these brain receptors in smokers can become hypersensitive.

According to Roger L. Papke, Ph.D., a professor of pharmacology at the University of Florida College of Medicine, the recently published findings represent a significant advancement in our knowledge of how nicotine receptors in the brain are impacted by coffee and cigarettes, even though they have not yet been tested on humans. Caffeine is the part in coffee that makes most people feel happy, however smokers may experience a different kind of boost.

Although many individuals enjoy caffeine in the morning, according to Papke, there are other chemicals in coffee that could help to explain why cigarette smokers enjoy their coffee.

Cells that express a particular human nicotine receptor were treated with a dark-roasted coffee solution by the researchers. The study's findings suggest that an organic chemical molecule found in coffee may aid in the restoration of nicotine receptor malfunction, which results in nicotine cravings in smokers.

The research has convinced Papke of a more general conclusion: n-MP, a substance found in brewed coffee, may help reduce morning cravings for nicotine.

The thought that nicotine-dependent smokers associate tobacco usage with drinking coffee in the morning and alcohol in the evening fascinated Papke, he added. The brain's nicotine receptors have been extensively examined in relation to alcohol, but less is known about how coffee affects those receptors.

"Due to the caffeine, many people seek out coffee in the morning. But what else was the coffee doing to the smokers? We were interested in learning if other components of coffee could influence the nicotine receptors in the brain, according to Papke.

The results, he claimed, offer behavioral experts a solid starting point for their continued investigation of nicotine withdrawal in animal models.

Do You Sleep on Your Back or Side? Here's The Research on 'Optimal' Sleep Positions

Image
William Dement, a renowned sleep researcher at Stanford University, is quoted as saying that after 50 years of study, the only reason he can think of for why we sleep is "because we become sleepy." Sleep certainly matters for our health and wellbeing even though it may be, as one researcher put it, "the sole major habit in quest of a function." Do we, however, have it right? What do studies on sleeping positions say? Is there a proper sleeping position? The majority of people favor sleeping on their side. This is encouraging news because people who sleep on their backs are more likely to have trouble falling asleep or breathing during the night. Most of the time, we have a tendency to shift around quite a bit at night. According to a study involving 664 sleepers, on average, participants slept on their side 54% of the time, their back 37% of the time, and their front 7% of the time. Males are more likely to change positions throughout the night and move their arms, ...

A Briefcase-Sized Box Is Already Making Oxygen on Mars

Image
Currently, the Martian atmosphere is in no way hospitable to Earthlings. It is formed primarily of carbon dioxide and is over 100 times less dense than Earth's atmosphere. It would soon stop breathing completely for any individuals who tried to breathe in it. A modest device, about the size of a suitcase, has been consistently extracting breathable oxygen from the Martian atmosphere on that sandy, arid, alien world. In order to manufacture breathing air for a human expedition to the red planet, it is the first demonstration of the processing of in situ resources for human use on another world. Its name is MOXIE (Mars Oxygen In-Situ Resource Utilization (ISRU) Experiment), and it is a device that utilizes electrolysis to separate Martian carbon dioxide into carbon monoxide and oxygen. It is mounted inside NASA's Perseverance rover. According to the researchers, MOXIE produced oxygen seven times as much between February 2021, when Perseverance arrived, until the end of 2021.

New DNA Research Unlocks Secrets of Native Rodents’ Rat Race to New Lands

Image
More than 150 different native rodent species from Australia, New Guinea, and Melanesian islands have had their DNA sequenced in recent studies. It provides a fuller understanding of their connections and the circumstances surrounding their expansion throughout the Pacific. The Australian National University's (ANU) Dr. Emily Roycroft, the study's lead author, said native rodents are an interesting but frequently underappreciated evolutionary group. Dr. Roycroft noted that over 150 species in Australia and New Guinea are unique to those regions and include the rakali, sometimes known as the "water rat," which is frequently spotted swimming in the lakes near Canberra. We now know relatively little about the history and development of native rodents, particularly those found in New Guinea. In order to obtain DNA from museum specimens up to 180 years old, including several extinct and secretive species, the study team developed a novel technique. "One Guadalcanal ra...
