When cells move about in the body, they follow a complex pattern similar to that which amoebae and bacteria use when searching for food, researchers have found.
 
 
The hippocampus, a part of the brain essential for memory, has long been known to "replay" recently experienced events. Previously, replay was believed to be a simple process of reviewing recent experiences in order to help consolidate them into long-term memory. However, new research shows the phenomenon of memory replay is much more complex, cognitive process that may help an animal maintain its internal representation of the world, or its cognitive map.
 
 
New studies of ripples and dunes shaped by the winds on Mars testify to variability on that planet, identifying at least one place where ripples are actively migrating and another where the ripples have been stationary for 100,000 years or more.
 
 
A study by Norwegian and French researchers hopes to provide new understanding of how blood cells adjust gene expression in response to various clinical, biochemical and pathological conditions. The Norwegian Woman and Cancer postgenome study highlights numerous blood gene sets affected by one's physical condition, lifestyle factors and exposure variables.
 
 
Since 2004, University at Buffalo anthropologist Ezra Zubrow has worked intensively with teams of scientists in the Arctic regions of St. James Bay, Quebec, northern Finland and Kamchatka to understand how humans living 4,000 to 6,000 years ago reacted to climate changes.
 
 
High energy levels cause glioblastoma cells to proliferate; low levels cause them to grow less and to migrate. This study discovered that a molecule called miR-451 coordinates this grow-or-go behavior, which is closely linked to the cells' ability to invade and spread. Thus, the molecule might be a biomarker for predicting survival in patients with glioblastoma multiforme and may serve as a target to develop drugs to fight these tumors.
 
 
A genetic study has found that small domestic dogs probably originated in the Middle East more than 12,000 years ago. Researchers have traced the evolutionary history of the IGF1 gene, finding that the version of the gene that is a major determinant of small size probably originated as a result of the domestication of the Middle Eastern gray wolf.
 
 
Scandinavian scientists have discovered that a species of tree defends itself from herbivore attack by using chemicals emitted by neighboring plants. The study reveals how species of Birch tree absorb chemical compounds from neighboring Marsh tea plants, Rhondodendron tomentosum, in a unique "defense by neighbor strategy."
 
 
One of the oldest available anti-seizure medications, ethosuximide, is the most effective treatment for childhood absence epilepsy, according to initial outcomes.
 
 
Rice students put calculations by German physicist Gustav Mie, made in 1908, to the test when they decided to look at the optical properties of single nanoparticles.
 
 
Entirely different signal paths and parts of the brain are involved when you try to remember something and when you just happen to remember something, prompted by a smell, a picture, or a word, for instance.
 
 
Flightless birds, blind cave shrimp, and other oddities suggest a "use it or lose it" tendency in evolution. In the microbial world, an unusual marine microorganism appears to have ditched several major metabolic pathways, leaving it with a remarkably reduced set of genes.
 
 
Approximately 21 million visits were made to physicians' offices due to back problems in 2006. While countless adults experience back pain and stiffness, many suffer from serious spine and back conditions -- including injury, herniated discs and the deterioration of the vertebrae. Three new studies detail advances in back care and treatment options for specific back and spine conditions.
 
 
Using green algae to produce hydrocarbon oil for biofuel production is nothing new; nature has been doing so for hundreds of millions of years, according a scientists.
 
 
Total knee replacement (TKR) successfully relieves pain and improves function in patients with advanced knee arthritis, according to a new study.
 
 
A research team has shown how PEGylated polylysine dendrimers, a new type of nano-sized drug delivery system, can be altered to target either the lymphatic system or the bloodstream, which may improve the treatment of particular types of diseases.

The genus name of chocolate, Theobroma derives from the Greek theos, “god,” and “broma,” “food,” thus meaning “food of the gods.” The common name chocolate derives from an Aztec name for this plant, chocolatl. Cocoa was the “love tonic” of Montezuma II, who is reputed to have drunk some fifty cups daily before visiting his [...]
 
 
Sunnier, longer days beckon us to enjoy more time outside, and to do the clothing switchover. Bye-bye corduroys, hello linen. As you pack away your down comforters, favorite sweaters or other items made of wool, be sure to steer clear of mothballs. First of all, they smell gross. When is the last time you paid someone [...]
 
 
While feng shui may not result in that winning lottery ticket you dream of (then again, it just might!), it brings many other benefits by creating a more harmonious and balanced flow of chi through your home. Just as fresh air, clean water and natural foods support the physical health of our bodies, so does [...]
 
 
Ok, I lied, it’s not the final word on Haiti, not that I could have that word anyway. After last week’s post, I had a few other thoughts (and a few things to add) and thought I’d shoot them out here. I only titled this post The Final Word, because after this I’ll [...]
 
 
Editor’s Note: The Cove won the Oscar for Best Feature Documentary! Congratulations! Thanks to the passionate filmmakers who spread awareness through this documentary and to viewers who took action, including those who signed the Care2 petition. Some articles just write themselves and some I just can’t get started. Well today, I’m stuck with the latter problem. [...]
 
 
By Kelly Rossiter, Planet Green The weekly grocery bill takes up a lot of the average family’s income so here are some ideas about how to trim down the bill. 1. Ditch prepared meals right now: Consumers have been led to believe that they don’t have the time to cook and it simply isn’t true. You can [...]
 
 
“The 800 lb. gorilla behind virtually all of the ’sustainability challenges’ is you and me, the consumer. The problem is not that we are bad, but that we have been blind to the impacts of our everyday choices which are about to change.” ~ Peter Senge, MIT Sloan School of Management As we watch the trend [...]
 
 
Sewing is a hobby with a budget-friendly heart. Making your own clothes or home décor often can be cost effective. But, those who frequent sewing stores know that sewing supplies and fabric can still be quite expensive. That is why it is a good idea to consider repurposing fabric and altering clothing items that you [...]
 
 
I spent two weeks in Haiti shortly after the earthquake and what I saw there was truly unreal. For starters, the devastation is beyond belief, bordering on the incomprehensible. You can look at pictures of what has happened, but to truly understand the scope of it, you need to see it firsthand. Essentially, the city [...]
 
 
I am told Cabin Fever is not a measurable or diagnosed affliction. But, it is getting capitalized here like any true disease with a name because I believe it is real. I bet you know many, many fine folks who have fallen ill with this degenerative mood-altering ailment. What, with the snow, ice, rain, slush, [...]

It's challenging for you to make definite plans now because you can see so many different ways to reach your goal. But you know that you are in trouble when the various routes appear to be more interesting than your final destination. Luckily, your current lack of focus is not a problem and won't be a setback to your ambitions. It will, however, enrich your experience if you have enough sense not to worry.
