Swarming bacteria “scream” when they die, warning their fellow bacteria of danger. These screams are not audible; instead, they are chemical alarms that the bacteria broadcast while on they are close to death, an action commonly referred to as necrosignaling. Through necrosignaling, bacteria alert their fellow bacteria to presence of a looming threat and save the majority of the swarm (a bacterial colony that is on the move). When confronted by a threat such as antibiotics, the bacteria’s chemical death cries can provide survivors enough time to go through mutations that develop antibiotic resistance, scientists have reported in a study. Several species of bacteria swim around with the support of long tail-like structures referred too as flagella, which helps them swiftly. And occasionally, bacteria such as Escherichia coli (E. coli) gather in the billions and use their flagella to move together over solid surfaces, as a swarm. “Bacterial swarms are…

Humans once thought our planet was the physical center of the solar system, so it is no surprise that we also think highly of consciousness, the apparently unique quality that allows our species to contemplate such issues. But what actually is consciousness? The subject has been extremely controversial in philosophic and scientific circles. Thinkers have spent an immeasurable amount of time and ink attempting to shine a light on some of the world’s biggest mysteries, such as how consciousness functions and where it is. The short answer is not particularly gratifying. Scientists and philosophers still cannot agree on a general idea of what consciousness is, much less a concrete definition. One reason for that is that the concept is used to mean a few different things. Some experts agree, however, that conscious beings are aware of their surroundings, themselves, and their own perception. But the long answer leaves room for…

What’s Holistic Health All About? Most people associate holistic health with alternative medicine. I am not here to teach you herbal drugs, acupuncture needles, or new treatment methods.

Check out 2 important practices we should incorporate into our daily life to embrace holistic health.   Feed the Stomach Without Forgetting the Brain! Holistic health should be our lifestyle and not just how we eat. There are countless diets to choose from.

Personality Shift

Between our teenage and adult years, we all go through a range of changes – unfortunate haircuts, jobs and relationships come and go. But what about who you are at your core? As you grow older, does your personality change? Personality is the pattern of thoughts, feelings and behaviours unique to a person. People tend to think of personality as an aspect of a person that is unchanging. But according to psychologists, that is not how it works. “Personality is a developmental phenomenon. It is not just a static thing that you are stuck with and cannot get over,” an expert psychologist says. That is not to say that you are a different person each and every day. In the short term, change can be nearly imperceptible, according to a study that surveyed the personalities of participants regularly over many years. This suggest suggests that our personality is actually fairly…

Never Gain Weight

It is one of life’s great injustices, some people must be extremely careful about what they eat in order to maintain a healthy weight, while others can eat all the deep fried food they like and see no dramatic shift in their weight. So how does this work? What are they doing that you are not? There is not a straightforward answer to this question, nutrition experts say, “There is genetic, nutritional, and even behavioural factors involved,”. Apparently, the extent to which each of those factors come into play in any given individual will vary. One of the most critical factors has little to do with body type, metabolism, or performing a spell during a full moon. It is perception. Many people appear to eat whatever they like without gaining weight are not actually eating more than the rest of us, experts note. For example, your friend who eats ice…
