Brain waves can be used to predict future pain sensitivity

Medley Brain 2

Rhythms produced by the brain can reliably be used to predict how sensitive we are to pain, new research shows.

The living brain is constantly producing regular rhythmic patterns of activity, which can be compared to musical notes. Scientists at the University of Birmingham in the UK, and the University of Maryland School of Dentistry in the US, have successfully demonstrated that one particularly prevalent pattern of brain activity, called alpha waves, strongly relates to the body's susceptibility or resilience to pain.

Exploding stars may have caused mass extinction on Earth, study shows

Medley SD 3 b Artists Rendering Exploding Star 777x518

Imagine reading by the light of an exploded star, brighter than a full moon -- it might be fun to think about, but this scene is the prelude to a disaster when the radiation devastates life as we know it. Killer cosmic rays from nearby supernovae could be the culprit behind at least one mass extinction event, researchers said, and finding certain radioactive isotopes in Earth's rock record could confirm this scenario.

A new study led by University of Illinois, Urbana-Champaign astronomy and physics professor Brian Fields explores the possibility that astronomical events were responsible for an extinction event 359 million years ago, at the boundary between the Devonian and Carboniferous periods.

The paper is published in the Proceedings of the National Academy of Sciences.

What are Words Worth?

Jan Nicolaas Kind – Brazil

Let’s face it, no matter what some might say, in many parts of the world political debates have entirely deteriorated. They have turned like going into combat – the gladiators are ready to fight, looking for any and every way to find flaws in the opponent’s argument, while minds are not open to the opponent’s beliefs. This type of debate, whereby the main objective is to destroy the opponent’s character and status. leads to mud throwing, insults and under the belt, personal attacks. Instead of elucidating debaters’ standpoint through utilizing rhetorical eloquence, the level of the deliberations has sunk so miserably low that watching such a confrontation has become the worst thinkable nightmare.

Conclusion: nowadays most political debates are unbrotherly and absolutely useless.

Seeking a home where he himself is free.

Managers transforming office culture

If you’re an employee with little control over your schedule, there might not be too many ideas for finding focus that you can implement during your work day. In that case, I suggest you

1) implement what you can; and

2) buy a copy of this book for your manager and/or upper management, and especially point them to this chapter.

The rest of this chapter is for management: CEOs, vice presidents, supervisors, middle managers, small employers. Bosses of all kinds. Anyone who controls the schedules of others, or has influence on the policies and office culture that determine how people work.
