The Free Will Debate

Image
While the problem of free will is as old as ancient Greece, modern neuroscience is breaking new ground with the debate while drawing into question our deepest notions of consciousness, morality, and society. In 1980, Benjamin Libet conducted a study in which he asked people to flex their wrists at random, while he read their brain activity. Libet recorded the time in which they thought of acting and compared it with his data. His results demonstrated that the subjects' brains made decisions milliseconds before they did. This led many scientists to believe that people’s decisions occur without free will – a position known as determinism.Nerve Prints, Cards and Phone Cases Skeptics of Libet's study argue that it only deals with decisions on an impulse level and that other more complex decisions, such as which career to pursue or who to marry, could still be up to free will. This view reflects the classic libertarian position that at least some of our actions are freely made. Ne…

The Energy Revolution

Renewable energy is sweeping the globe, changing our economies and the way we impact the environment.Wind farms and solar panels now power large parts of developed countries and hydropower is constantly innovating, becoming more efficient and cost-effective. Tesla's SolarCity recently released a new solar power roof, and there is talk that one-day solar panels might replace household windows, potentially reducing electric bills and carbon footprints to zero.Stock Images and Stock Video of Renewable Energy Since 2014, both the United States and the European Union have reduced their CO2 emissions, and many other developed nations have seen their emission rates decline or stabilize.

Summertime: Rising Both Temperatures and Skin Cancer Concerns

Image
Beach weather gives us the opportunity to get outdoors, enjoy the fresh air, and soak up some Vitamin D, but also brings concerns about excessive sun exposure. With stronger and more frequent sun comes a higher risk for skin to be damaged by UV rays, making the body more susceptible to skin cancer. Skin cancer is one of the most common types of cancer. The Skin Cancer Foundation states that more people are diagnosed with skin cancer each year in the U.S. than all other cancers combined. The cause is most often UV rays from the sun or tanning beds. Skin cancer is generally categorized into two groups, melanoma, and nonmelanoma. Melanoma cancer begins in melanocytes, which are cells that produce skin pigment (melanin) and reside deep within the epidermis (the outer layer of the skin). Melanoma is known to often be more serious than nonmelanoma cancer because it has the tendency to advance and spread rapidly. The number of new melanoma cases are also on the rise. That being said, the ea…

Retro Summer Fun

Image
Many things have changed over the past decades, but we still look forward to the joys of summer and long, warm days of fun and relaxation. By the seaside, we still swim, build sandcastles, collect seashells, run in the sand, and sunbathe. In the woods, we enjoy a relaxing canoe paddle, a family picnic, watching butterflies, or a hike while soaking in the beauty of nature. Closer to home we do backyard cookouts, golf, ride a bike, swing on a swing, eat watermelon, play baseball or just fly a kite.Retro Stock Images of People Enjoying Summer With longer days and warm sunshine, we don't even mind outdoor chores such as mowing the lawn. Being outdoors longer has added health benefits. More and more studies show that spending time outside gives us an emotional boost. Summer improves our capacity for happiness and well-being.

Cardio is great for shedding pounds as well as boosting the health of your heart and lungs. When taking on some endurance training, your metabolism speeds up and more oxygen is able to be distributed throughout your body. This makes the heart stronger and able to distribute blood more effic…
