Alcohol Makes Rats Turn To Cocaine The most common research involving alcohol typically concerns its effect on humans. One area of particular interest is its addictiveness and if alcohol will leave you more vulnerable to drug use. A study from 2017 supported this idea by showing that drunk rats like  cocaine . During the experiment, rats were given alcohol for ten days before being offered cocaine. Afterward, the animals proceeded to consume the drug despite being administered an electrical shock each time they did so. Overall, these rats attempted to “score” by pressing a lever an average of 58 times, while a control group which was given water only did it 18 times. This kind of compulsive behavior is found in about a quarter of human cocaine users. While it is common for these people’s cocaine addiction to be preceded by other  substance abuse , the biological mechanism which prompts certain drugs to act as “gateways” is still poorly understood. This study suggests that, at

Jin Shang, a professor of biochemical engineering at the University of Western Ontario, has invented a contact lens that changes color when sugar levels change in the blood. Those suffering from diabetes need to draw blood to check sugar levels. Nanoparticles implanted in contact lenses interact with glucose molecules in tears. This interaction changes the color of the lens to indicate varying sugar levels. This new medical invention could eliminate the need to draw blood to monitor glucose.

Though the practices of astrology and astronomy have common roots, there is an important distinction in astrology vs astronomy today. Astronomy is the study of the universe and its contents outside of Earth’s atmosphere. Astronomers examine the positions, motions, and properties of celestial objects. Astrology attempts to study how those positions, motions, and properties affect people and events on Earth. For several millennia, the desire to improve astrological predictions was one of the main motivations for astronomical observations and theories. Andreas Cellarius's illustration of the Ptolemaic System (17th century), which shows the solar system and signs of the zodiac with the Earth at the center. J. van Loon, National Library of Australia Astrology vs Astronomy Astrology continued to be part of mainstream science until the late 1600s, when Isaac Newton demonstrated some of the physical processes by which celestial bodies affect each other. In doing so, he showed that the s
