Photography is an interesting task that inspires many people to inspire many others. It starts from the art of creativity and imagination, goes from the science of click and light, and ends with a beautiful memory in the hand or book. For some people, this memory helps them in earning more memories.
So, one of my favorite ideas to earn more memories is through Dreamstime. You can join Dreamstime to earn money and help others to earn money through photography, here:

Alzheimer’s disease is a degenerative brain disorder that is similar to senile dementia except that it begins in the later stages of life, usually after 40 years. Among the first signs and symptoms of the disease are impaired memory along with impaired thought and speech. However, these signs and symptoms appear after a significant damage to the brain.
This disease (along with many other psychiatric problems such as Parkinson’s) can be detected by doctors and experts with the help........ Read more »

Eating dark chocolate can help in increasing attention levels, thereby improving concentration.
Chocolate is a food made from roasted ground cacao beans. It is a powerful stimulant that can activate the brain. It is helpful in increasing the attention capabilities, and can also influence blood pressure as it is a vasodilator, i.e. it opens blood vessels and decreases blood pressure.
In a recent research, scientists tried ........ Read more »

You can enhance your memory nearly five times with the help of 45-60 minutes of sleep.
Neurobiology of Learning and Memory
Memory is the power of retaining, remembering, and recalling past experiences and knowledge. Normally, new information moves away from the mind quite rapidly as we are prone to forget things. Every one of us wants to have a good memory. Researchers are working on new techniques to improve memory that may range from exer........ Read more »

“Two possibilities exist: Either we are alone in the Universe or we are not. Both are equally terrifying” (Arthur C. Clarke)
Life on Earth is a common thing. Life on clouds and in water looks interesting. And life on places other than the Earth (extraterrestrial life) looks…ummmm…possible. In this article, I will try to note some information ranging from hypothesis to scientific information related to the life on places other than Earth.

Freelance writing is an interesting career.
“The only safe thing is to take a chance.” (Mike Nichols)
By definition Freelancing means working for yourself. A freelancer works as a writer and/or artist, and sells his or her services to different employers without any long-term contract. According to a report (Fell, 2014), nearly 34% of people working in America are freelancers. Among the top most freelancing jobs are writing, education, grap........ Read more »

Growing with time and becoming old is a common phenomenon. Every person grows older with time, but some people may have the wish to grow old faster. So, this article is for those people. On the contrary, if you want to feel young and good, do the opposite as mentioned in this article.
Think that you are old
It has been found that self-perceived age is strongly related to cardiovascular health. It is important to think that you are older. Researchers have found that older people, who think th........ Read more »
Viruses are important in making us smarter by improving the basic functions of the brain, especially the regulation of gene expressions.
Researchers from Lund University in Sweden have found that millions of year’s old inherited viruses can have special impact on the development of complex networks in the brain of human beings.
Previously, it was clear that endogenous retroviruses make nearly 5% of DNA of human beings,........ Read more »

Many people are unaware of their mathematics-related abilities, and these abilities have to be considered in their evaluations and life outcomes.
Journal of Personal and Social Psychology
Mathematics is one of the most disliked subjects of students. It is probably due to its logical dealing with the quantity, shape, and arrangements, but interesting part of the life is that many people have no clue about their mathematics-related abilities,........ Read more »

Simple answer to this question is to have a regular sleep at proper time in the night.
Cognitive Therapy and Research
Researchers have reported that “Duration and Timing of Sleep are Associated with Repetitive Negative Thinking”. They have defined Repetitive Negative Thinking (RNT) as “a perseverative and abstract focus on negative aspects of one’s experience”.
Usually, people complain about repetitive negative thoughts affecti........ Read more »

Don’t worry, if your children don’t like to eat fruits and vegetables. You have only to involve them in cooking or food preparation classes to increase their taste and willingness for these things.

Guessing even the wrong answer could help in learning the right answer.
Memory & Cognition
Researchers from the University of California, Los Angeles, worked on some volunteers and gave them some pairs of words. Some participants were given the word pairs to study, and others were asked to guess the pairs of words before showing the right answer. Researchers found that guessing process, even when it is wrong, helps in better learning of wor........ Read more »

Babies, even 15-months-old, can identify the anger of adults. Interestingly, they have the ability to change their behavior in response to anger.
Psychologists have found that babies not only learn from their own social experiences but also from looking at social interactions of other people. This shows that babies have a good level of emotional intelligence that could be more than we think. They start learning about s........ Read more »

1.Blind people can't see in dreams:
Blind people are unable to see even in their dreams but they get a rich combination of different senses in their dreams. They get more feelings of taste, smell, touch, and hear in their dreams as compared to normal people.

Scientists have opened a new window in science by finding that an effective magnetic field can exist for light.
Magnetic field refers to the line of forces that are present around the permanent magnet or a moving charged particle. This field can change the path of charged particles such as electrons. Usually, magnetic field has no effect on neutral particles such as photons, which are present in light. However, the present stu........ Read more »

Nerve endings on our fingertips have the same ability of performing complex neural computations as we can find in our brain.
Researchers have found that our fingertips are able to differentiate the edges and this process of getting knowledge of orientation of edges is performed by both touch and visual senses. Most of these senses and computations occur in the brain as it contains cells of both touch and see that are s........ Read more »
