The Arrow of Time, or Time's Arrow, is a concept developed in 1927 by the British astronomer Arthur Eddington involving the "one-way direction" or "asymmetry" of time. Currently theoretical physicists have developed a fully-symmetric formulation of quantum theory which establishes an exact link between asymmetry and the fact that we can remember the past but not the future. The laws of classical mechanics are independent of the direction of time, but whether the same is true in quantum mechanics has been a subject of debate. Read More ...

One of the enduring mysteries of the human experience is how and why humans moved from hunting and gathering to farming. From their beginnings humans, like other mammals, depended on wild resources for sustenance. Then between 8,000 and 12,000 years ago, in a transitional event known as the Neolithic Revolution, they began to create and tend domestic ecosystems in various locations around the world, and agriculture was born. Despite decades of research into this major human advancement, scientists still don't know what propelled it.

Social anxiety is a specific form of anxiety. It is an emotion characterized by a discomfort or a fear when a person is in a social interaction that involves a concern of being judged or evaluated by others. It is typically characterized by an intense fear of what others are thinking about them (specifically fear of embarrassment or humiliation, criticism, or rejection), which results in the individual feeling insecure and not good enough for other people, and/or the assumption that peers will automatically reject them.

According to a new study - One night of sleep loss can alter clock genes in your tissues. Previous research has shown that our metabolism is negatively affected by sleep loss also linked to an increased risk of obesity and type 2 diabetes. Since ablation of clock genes in animals can cause these disease states, our current results indicate that changes of our clock genes may be linked to such negative effects caused by sleep loss. Sleep
