Cancer in demise: mortality rate plummets by 19.5% since 1991

Some people tend to believe that today’s society is excessively being eaten up by cancer, which is true to a certain degree. A lot more people are dying of cancer today than 100 years ago, but not because of GMO foods or chemtrails. The main reason people are dying of cancer is old age. In 1900, the average American lifespan…

Automated tasks are still processed while you sleep

sleep

Despite an incredible body of work dedicated to researching what goes inside the brain while we sleep, consensus among neuroscientists suggests we’re just beginning to scratch the surface. For instance, we’ve yet to answer a fundamental question: why do we need sleep? We all agree that we needed it  – going without sleep for long periods of time can bring…

What really causes aging? Study suggests “parasitic DNA fragments”

Sirt6 has many functions to play in the body. Image via Nature.

Most organisms, including humans, have parasitic DNA fragments called ‘jumping genes’ that insert themselves into DNA molecules, disrupting genetic instructions in the process. This phenomenon can interfere with the good health of the individual, causing numerous conditions, including cancer. Now, a new study has documented how a protein called Sirt6 keeps these fragments (technically called retrotransposons) at bay. Better understanding this mechanism…

Heart rate variability keeps the body in optimal shape

heartrate

The heart regularly speeds up or down its beating frequency to adjust to the body’s needs. Even in stable conditions (when you’re not particularly active or your active for a constant time), the amount of time between heart beats is variable. A team of doctors and engineers at Caltech’s Division of Engineering and Applied Science have now found a better way to assess…

Gut bacteria may control your mind by influencing your dietary choices

gut_bacteria_food_craving

Our gut hosts an enormous population of bacteria, each species with its own niche (they feed on certain foods), which outnumbers our own cells 100-fold. Most of these bacteria are good bacteria, though. In fact, you couldn’t survive without most of them! They’re among the best decomposers, breaking down dead and organic matter otherwise impossible by the gut alone. But…

Nature walks linked to significantly lower depression and stress

depression walk nature

Science confirms what many already believed: taking walks in nature lowers your stress and depression rates. You’ve probably heard it several times in your life: take a deep breath, go take a walk and calm down. But according to a new study, that’s not just small talk; walks, especially nature walks can do wonders for your mental health. Even people…

What goes on in an altruist’s head: good deeds may be rooted in the brain

Costly altruism, the kind that you see expressed by people who willingly agree or seek to donate their kidneys, is a puzzling phenomenon for many scientists. Most of these people would tell you that they do it out of love, sympathy or a higher purpose. Neuroscientists, however, are more interested in finding whether there are any neural mechanisms associated with…

Newly discovered ‘sleep node’ in the brain puts you to sleep without sedatives

Neuroscientists at University of Buffalo have identified a sleep-promoting circuit inside the brainstem or the primitive part of the brain, whose activity appears to be both necessary and sufficient to produce deep sleep. This is only the second ‘sleep node’ in the mammalian brain that was identified to serve this function. To demonstrate the sleep node’s function, the researchers used…
