Freud’s impact on 20 th cent
Full Moon Is Bad, But Supermoon Is Even Worse for Motorcyclists ::::: The bright light of a full moon or supermoon may seem inviting to motorcyclists eager for a nighttime ride, but that moonlit trip may also come with deadly consequences, a new study finds.

The immune cells that help tumors instead of destroying them ::::: Lung cancer is the leading cause of cancer-associated deaths. One of the most promising ways to treat it is by immunotherapy, a strategy that turns the patient's immune system against the tumor.

What do high school athletes, their parents and coaches know about concussion? ::::: ROCHESTER, Minn. — Most high school athletes, their parents and coaches can identify the possible effects of concussion, but only about one-third know that it is a brain injury. Those findings are outlined in a new Mayo Clinic study. Athletes were more likely than parents and coaches to correctly identify a concussion as a brain injury. Identifying trends and gaps in knowledge can guide help edu

Why Highly Intelligent People Suffer More Mental and Physical Disorders ::::: People with high IQ are considered to have an advantage in many domains. They are predicted to have higher educational attainment, better jobs, and a higher income level. Yet, it turns out that a high IQ is also associated with various mental and immunological diseases like depression, bipolar disorder, anxiety, ADHD as well as allergies, asthma, and immune disorders. Why is that? A new paper pub
Why most meteoroids blow up before they hit Earth ::::: When a meteoroid enters Earth’s atmosphere, the high-pressure air in front of it seeps into its pores, cracking the meteoroid, pushing its body apart, and causing it to explode, new research suggests. “There’s a big gradient between high-pressure air in front of the meteor and the vacuum of air behind it,” says Jay Melosh, a professor of Earth, atmospheric, and planetary sciences at Purdue Univer

Wind Turbines May Turn Slower in a Warmer World ::::: Global warming could be causing long-term shifts in the generation of wind energy. New research published yesterday in the journal Nature Geoscience suggests that future climate change might cause wind resources to decline across the Northern Hemisphere. These losses could be tempered by increases in wind power potential south of the equator, under severe climate change scenarios. The fin
