Photo by Greg Luna. 20 July 2010 — It's no secret to any dog-lover or cat-lover that humans have a special connection with animals. "Establishing an intimate connection to other animals is unique and universal to our species," said Shipman, a professor of biological anthropology. In addition to describing her theory in the scientific paper, Shipman has authored a book for the general public, now in press with W. These carvings are from ivory and have been dated to between 30,000 - 36,000 years old, making them the oldest artworks in Europe. Shipman suggests that the animal connection was prompted by the invention of stone tools 2.6-million years ago. Click on image for high-resolution version. [ Kevin Stacey ]

10 Simple Truths Smart People Forget Email Some of the smartest people I know continuously struggle to get ahead because they forget to address a few simple truths that collectively govern our potential to make progress. So here’s a quick reminder: #1 – Education and intelligence accomplish nothing without action. It doesn’t matter if you have a genius IQ and a PhD in Quantum Physics, you can’t change anything or make any sort of real-world progress without taking action. #2 – Happiness and success are two different things. I know an extremely savvy businesswoman who made almost a million dollars online last year. I also know a surfer who surfs almost all day, every day on the beach in front of our condo complex in San Diego. “What will make me happy?” #3 – Everyone runs their own business. No matter how you make a living or who you think you work for, you only work for one person, yourself. So how can you simultaneously save your time and increase your profit? is a good read on this topic. And that’s okay. Photo by: Alemdag

Entoptic phenomenon Entoptic phenomena (from Greek ἐντός "within" and ὀπτικός "visual") are visual effects whose source is within the eye itself. (Occasionally, these are called entopic phenomena, which is probably a typographical mistake.) In Helmholtz's words; "Under suitable conditions light falling on the eye may render visible certain objects within the eye itself. These perceptions are called entoptical." Entoptic images have a physical basis in the image cast upon the retina. Helmholtz[1] comments on phenomena which could be seen easily by some observers, but could not be seen at all by others. During the 1920s, some theosophists, unaware of the physical explanation, maintained that the moving spots seen in the blue field entoptic phenomenon were "vitality globules" related to the concept of prana in yoga.[2] Some examples of entoptical effects include: Floaters depiction Purkinje Tree depiction See also[edit] Notes[edit] ^ Jan E.

- StumbleUpon Studies have shown that meditating regularly can help relieve symptoms in people who suffer from chronic pain, but the neural mechanisms underlying the relief were unclear. Now, MIT and Harvard researchers have found a possible explanation for this phenomenon. In a study published online April 21 in the journal Brain Research Bulletin, the researchers found that people trained to meditate over an eight-week period were better able to control a specific type of brain waves called alpha rhythms. “These activity patterns are thought to minimize distractions, to diminish the likelihood stimuli will grab your attention,” says Christopher Moore, an MIT neuroscientist and senior author of the paper. “Our data indicate that meditation training makes you better at focusing, in part by allowing you to better regulate how things that arise will impact you.” A 1966 study showed that a group of Buddhist monks who meditated regularly had elevated alpha rhythms across their brains.

Alligators: A Window Into An Ancient World How amazing is it that we have creatures as old as dinosaurs living in our midst? Close ancestors of the alligator survived the event that wiped out the dinosaurs about 65 million years ago and as this graphic from the History Channel and Column Five details, there are some fascinating and unusual facts about the large reptile. Thanks to alligators, we have a window into how ancient creatures looked and acted. Food for thought: while alligator populations are currently large in the southern US, a place where the temperature supports the proper range for hatching eggs, it’s interesting to note how small a change in global temperature would select only one sex of offspring (as sex is determined by temperature during incubation). How much will global warming change the range and the population of alligators in the future? Click here or the image below for a full sized view:

The Top 10 Psychology Studies of 2010 The end of 2010 fast approaches, and I'm thrilled to have been asked by the editors of Psychology Today to write about the Top 10 psychology studies of the year. I've focused on studies that I personally feel stand out, not only as examples of great science, but even more importantly, as examples of how the science of psychology can improve our lives. Each study has a clear "take home" message, offering the reader an insight or a simple strategy they can use to reach their goals , strengthen their relationships, make better decisions, or become happier. If you extract the wisdom from these ten studies and apply them in your own life, 2011 just might be a very good year. 1) How to Break Bad Habits If you are trying to stop smoking , swearing, or chewing your nails, you have probably tried the strategy of distracting yourself - taking your mind off whatever it is you are trying not to do - to break the habit.

UCSB scientists discover how the brain encodes memories at a cellular level (Santa Barbara, Calif.) –– Scientists at UC Santa Barbara have made a major discovery in how the brain encodes memories. The finding, published in the December 24 issue of the journal Neuron, could eventually lead to the development of new drugs to aid memory. The team of scientists is the first to uncover a central process in encoding memories that occurs at the level of the synapse, where neurons connect with each other. "When we learn new things, when we store memories, there are a number of things that have to happen," said senior author Kenneth S. "One of the most important processes is that the synapses –– which cement those memories into place –– have to be strengthened," said Kosik. This is a neuron. (Photo Credit: Sourav Banerjee) Part of strengthening a synapse involves making new proteins. The production of new proteins can only occur when the RNA that will make the required proteins is turned on. When the signal comes in, the wrapping protein degrades or gets fragmented.

47 Mind-Blowing Psychology-Proven Facts You Should Know About Yourself - StumbleUpon I’ve decided to start a series called 100 Things You Should Know about People. As in: 100 things you should know if you are going to design an effective and persuasive website, web application or software application. Or maybe just 100 things that everyone should know about humans! The order that I’ll present these 100 things is going to be pretty random. So the fact that this first one is first doesn’t mean that’s it’s the most important.. just that it came to mind first. Dr. <div class="slide-intro-bottom"><a href="

60 insane cloud formations from around the world [PICs] Cloud varieties go way beyond the cumulus, stratus, and cirrus we learn about in elementary school. Check out these wild natural phenomena. STANDING IN A CORNFIELD IN INDIANA, I once saw a fat roll cloud (like #4 below) float directly over my head. It’s a 12-year-old memory that remains fresh. I imagine a lot of these photographers having similar hesitations as they set up for the shots below.

Preface For over a decade I have taught an introductory, undergraduate class, "Einstein for Everyone," at the University of Pittsburgh to anyone interested enough to walk through door. With each new offering of the course, I had the chance to find out what content worked and which of my ever so clever pedagogical inventions were failures. At the same time, my lecture notes have evolved. Its content reflects the fact that my interest lies in history and philosophy of science and that I teach in a Department of History and Philosophy of Science. This text owes a lot to many. i i i
