An Elephants Memory

In a top of intelligence, humans are followed by apes, elephants and dolphins. The elephant brain is denser than the human’s, and the temporal lobes, associated to memory, are more developed than in humans.

Elephant’s lobes also have more foldings, so that they can store more information. That’s why elephants have excellent memory.

But why? Elephants can recognize over 200 different individuals. This is essential, as females depend on one another for raising the young, more than in the case of other mammals. A mother can remember who is trustful and complex bounds are the bricks of elephants’ society, while the memory is the cement. When two elephants approach one another, they emit a “contact appeal”: if the other recognizes the appeal, it responds and approaches; if not, it starts to agitate and adopts a defensive position. This capacity of recognition lasts a very long time, even after one individual is dead: even the recording of a dead animal attracted the attention of its relatives and descendants.

The group life allows the elephants to raise their young together. A female gives birth, in the best case, to one young every 4 years, and this one will be well cared.

In critical moments, the family stand on the experience of the oldest and wisest female in the group, called matriarch. She controls the daily activity of the herd and leads the family in areas outside the normal domain. Now, her remarkable memory is employed. She will remember where to go during drought periods and what to do in case of danger, as she already passed through these situations, and the older she is, the more effective she is. Her death is tragic for the group, and poachers usually target her, as she possesses the largest tusks in the herd of females.

Some consider elephants to posses consciousness: they have emotions and feelings one for another. The way how they behave with the body of a dead elephant seems to confirm this. It’s like they would understand death. They turn the bones and examine each crack, like wanting to wake up a sleeping baby

Genius hour Learning from failure

Some classrooms are adopting “genius hour” time — inspired by Google’s 20% time idea — to allow students to pursue passion projects. But how do students spend their time? 140305114338-05-genius-hour-horizontal-gallery
Here, fourth grader Mushkale Uppal collaborated with friends to build a robot for genius hour in Robyn Thiessen’s class at Green Timbers Elementary in Surrey, British Columbia. “It opened up my creative side,” he said.

Mushkale’s classmate Kiran Rai says she learned an important lesson while attempting to make cookies in the shape of sunglasses for genius hour: It’s OK to mess up.Screen shot 2014-03-17 at 6.37.32 AM She also discovered she could learn from mistakes to improve her technique and that she could pivot — that led to these tasty cookie flowers with licorice for stems.

“I asked my students what they liked about this project and the most common response was that they loved the freedom to explore what they are passionate about instead of just doing the work they have been assigned by teachers. That freedom is what motivates them to explore big ideas and take ownership of their learning.Screen shot 2014-03-17 at 6.39.53 AM

 

 

Negatives and Positives of Solar Energy

Solar energy has the potential to dramatically change the way the world gets its power. Enough solar energy falls on a 100-square-mile area of the southwestern United States to power the entire nation. It is still important, however, to understand the environmental impacts associated with producing power from renewable sources such as wind, solar, geothermal, biomass, and hydropower.

While solar is among the world’s cleanest forms of energy, plans to develop utility scale solar farms have raised concerns about potential environmental impacts.

One person’s beauty is another person’s eyesore. For some, solar panels evoke positive feelings, even when set in a natural landscape

Creating energy is a water intensive process. In the U.S., electricity production accounts for more than 40 percent of all daily freshwater withdrawals

Lower Your Blood Pressure

Vegetarian diet may lower your blood pressure

Nearly a third of American adults have high blood pressure, also known as hypertension. Often called the “silent killer” because it provides few warning signs, hypertension increases a patient’s risk for heart attack and stroke.

A healthy blood pressure is 120/80 mm HG. Previous studies have shown that each increase of 20/10 mm Hg in that number doubles the patient’s risk of cardiovascular disease. But lowering that top number just 5 mm HG can reduce your chances of dying from cardiovascular disease by about 7%. And eating more fruits and vegetables may be a good way to do that, according to the new study, published Monday in the scientific journal JAMA Internal Medicine.

Many factors could be affecting the vegetarians’ blood pressure. Vegetarian diets are often lower in sodium and saturated fats, while being higher in fiber and potassium.

Vegetarians also tend to have lower body mass indexes because fruits and vegetables are less energy dense – meaning you can eat more of them for fewer calories.

What is in y-our Water?

Dr Mona Harris breaks down what exactly is put in our water to keep it “clean”. How these cleaning agents are effecting our brain and why is it being done! Captivating information that must be passed on for the sake of health. Dr Mona passed away shortly after releasing a series of videos detailing the system of control behind drinking water.

Hemp Is in!

WASHINGTON — Farm legislation breezing through Congress could make northern Colorado the nation’s leader in the cultivation, study and use of industrial hemp.

The farm bill provision authored by Rep. Jared Polis, D-Colo., and Reps. Thomas Massie, R-Ky., and Earl Blumenauer, D-Ore., would allow colleges, universities and state agriculture agencies to grow and do research on the crop without being penalized by the federal government.

Scientists find new brain area for anxiety

Researchers have discovered that an area of the brain that was previously assumed to dampen response to stress, in fact does the opposite and directly promotes anxiety. In reporting their findings in the journal Cell, the investigators add a new dimension to the science of anxiety

They describe how they found a brain circuit that connects an area called the lateral septum (LS) with other brain structures in a way that directly affects anxiety.

Corresponding author David Anderson, the Seymour Benzer Professor of Biology at California Institute of Technology (Caltech) in Pasadena, says:

“Our study has identified a new neural circuit that plays a causal role in promoting anxiety states. Part of the reason we lack more effective and specific drugs for anxiety is that we don’t know enough about how the brain processes anxiety. This study opens up a new line of investigation into the brain circuitry that controls anxiety.”

Figures from the National Institutes of Mental Health show over 18% of adults in the US are affected by anxiety disorders, where people experience excessive worry or tension, often leading to physical symptoms.

Although previous research has focused primarily on the amygdala as being the region in the brain that processes anxiety, Prof. Anderson and colleagues had a hunch that the LS might also be involved, so they decided to study it using mice.
