To a modern physicist working with Einstein's general theory of relativity , the situation is even more complicated than is suggested above. Einstein's theory suggests that it actually is valid to consider that objects in inertial motion (such as falling in an elevator, or in a parabola in an airplane, or orbiting a planet) can indeed be considered to experience a local loss of the gravitational field in their rest frame. Thus, in the point of view (or frame) of the astronaut or orbiting ship, there actually is nearly-zero proper acceleration (the acceleration felt locally), just as would be the case far out in space, away from any mass. It is thus valid to consider that most of the gravitational field in such situations is actually absent from the point of view of the falling observer, just as the colloquial view suggests (see equivalence principle for a fuller explanation of this point). However, this loss of gravity for the falling or orbiting observer, in Einstein's theory, is due to the falling motion itself, and (again as in Newton's theory) not due to increased distance from the Earth. However, the gravity nevertheless is considered to be absent. In fact, Einstein's realization that a pure gravitational interaction cannot be felt, if all other forces are removed, was the key insight to leading him to the view that the gravitational "force" can in some ways be viewed as non-existent. Rather, objects tend to follow geodesic paths in curved space-time, and this is "explained" as a force, by "Newtonian" observers who assume that space-time is "flat," and thus do not have a reason for curved paths (., the "falling motion" of an object near a gravitational source).

A research by the Harvard Medical School , internal and external stress can all contribute to a person relapsing into addictive behavior. When you get addicted, your amygdale (which is associated with emotions), your hippocampus (which is associated with memory), the nucleus accumbens (which is associated with high dopamine levels), and the corticotrophin hormone (which is released during stress) are all working together. As a result, your mood, the people around you, and your experiences can all trigger this network and cause the addictive behavior. This is the reason why an addict relapses after smelling a cigarette, experiencing a stressful situation, or after seeing a sexual video image.

New report finds that short-sighted agendas of “Trump Era” politicians are driving new . policies, which may dangerously increase population size and growth.
After repeated Congressional attempts to defund Planned Parenthood and repeal the Affordable Care Act (ACA), Negative Population Growth (NPG) will release a new Forum paper today.  The NPG report analyzes the impact of current conservative stances on both reproductive healthcare and foreign aid policy, finding that each will likely result in decreased access to contraceptive and family planning resources for millions. […]

On July 26, 2000 the American Academy of Pediatrics, the American Medical Association, the American Psychological Association, the American Academy of Family Physicians, and the American Academy of Child and Adolescent Psychiatry stated that "prolonged viewing of media violence can lead to emotional desensitization toward violence in real life." [32] However, scholars have since analyzed several statements in this release, both about the number of studies conducted, and a comparison with medical effects, and found many errors (Block & Crain, 2007; Freedman, 2002).
