High-Intensity Circuit Training Using Body Weight: Maximum Results With Minimal Investment

Time and access to facility constraints can be a concern when it comes to getting people to exercise. High-intensity circuit training seems to deliver numerous health benefits in less time than more traditional programs that are recommended. Furthermore, body weight can be used as resistance, eliminating the need for specialized facilities or equipment.

Cell biology: The new cell anatomy

Interesting article (from Nov 2011 Cell Biology): The new cell anatomy

“These days, textbook diagrams of cell structures such as the nucleus, mitochondrion, ribosome and Golgi apparatus are beginning to seem out of date. New imaging techniques, genome data, interest from disciplines outside cell biology and a bit of serendipity are drawing attention to an intricate landscape of tubes, sacs, clumps, strands and capsules that may be involved in everything from intercellular communication to metabolic efficiency. Some could even be harnessed for use in drug delivery or in synthesis of industrial products, such as biofuels.”

“Here Dr. Sacks recounts the case histories of patients lost in the bizarre, apparently inescapable world of neurological disorders: people afflicted with fantastic perceptual and intellectual aberrations; patients who have lost their memories and with them the greater part of their pasts; who are no longer able to recognize people and common objects; who are stricken with violent tics and grimaces or who shout involuntary obscenities; whose limbs have become alien; who have been dismissed as retarded yet are gifted with uncanny artistic or mathematical talents.”
