Carl Sagan’s Two Warnings For Humanity In His Very Last Interview

Carl Sagan was an astronomer, astrophysicist, cosmologist, skeptic and critical thinker. He was the Professor of Astronomy and Space Sciences and Director of the Laboratory for Planetary Studies at Cornell University. He played a leading role in the American space program and was a consultant and adviser to NASA since the late 1950′s. He was also responsible for briefing the Apollo astronauts before their flights to the Moon. Many of you might know him from some of his bestselling books, like Cosmos, which was in fact the bestselling science book ever published in the English language.

Sagan was responsible for assisting humanity in their knowledge of concepts that are outside of the box, these include multiple dimensions, quantum physics, wormholes, and a wide variety of ideas and concepts about space, science, technology and more. He did so with a great amount of enthusiasm, cheer, and an uplifting type of energy.  In his very last interview he left us with words that might give you goosebumps,he issued two warnings  to the human race.

His first concern was with regards to science and technology. Sagan expressed great concern that“if the general public doesn’t understand science and technology, then who is making all of the decisions about science and technology that are going to determine what kind of future our children live in, some members of congress? There are only a handful who have any background in science at all, and some of them don’t even want to know about it.” – Carl Sagan

Scientists have developed an "off-switch" for the brain

Research could help towards developing treatment for neurological disorders such as epilepsy

Scientists have developed an “off-switch” for the brain to effectively shut down neural activity using light pulses.

In 2005, Stanford scientist Karl Deisseroth discovered how to switch individual brain cells on and off by using light in a technique he dubbed 'optogenetics'.

Research teams around the world have since used this technique to study brain cells, heart cells, stem cells and others regulated by electrical signals.

However, light-sensitive proteins were efficient at switching cells on but proved less effective at turning them off.

Now, after almost a decade of research, scientists have been able to shut down the neurons as well as activate them.

Earth's oldest crater yields new secrets

Geologists are still making discoveries in South Africa's Vredefort impact crater, the biggest on Earth.

Geologists say they've discovered rocks long thought vanished, the youngest remains of the oldest and biggest impact crater on Earth.

5 strange facts about memory

Memory can be a playful thing. It collects minute details from childhood events, yet leaves us wondering where we left our keys.

 

There are several types of memories, and the brain has a unique way of forgetting each kind. Psychologists have classified various ways by which we forget, and biologists have studied forgetting mechanisms at the cellular level.

 

They've found that forgetting is normal, and actually vital to how the brain works. Here is a look at the strange facts about how people forget things.

Mixing Honey and Cinnamon Cures Most Diseases

Today’s Science Has Found That Mixing Honey and Cinnamon Cures Most Diseases

Interesting stuff!!
Cinnamon and Honey

Drug companies won’t like this one getting around. Facts on Honey and Cinnamon:
It is found that a mix of honey and Cinnamon cures most diseases. Honey is produced in most of the countries of the world. Scientists of today also note honey as very effective medicine for all kinds of diseases. Honey can be used without side effects which is also a plus.Today’s science says that even though honey is sweet, when it is taken in the right dosage as a medicine, it does not harm even diabetic patients.

Amazing Things Scientists Have Discovered About Psychedelics

Psychedelics have the potential to treat cancers, addiction and psychological traumas.

ApriDespite the fact that the U.S. government deems many hallucinogenic or psychedelic substances to be dangerous, classifying them as Schedule I drugs with “no currently accepted medical use,” various scientists have dared to study their effects. What they’ve found over the years paints a startling, promising and powerful picture of potentially game-changing medicines.

The government’s "war on drugs" policies severely limit research on psychedelics. Before scientists can complete any federally sanctioned studies, they have to jump through an expensive tangle of hoops and red tape. Restrictions aside, over the years researchers have collected a database of research showing that many psychedelics have an unprecedented potential to treat cancers, addictions and psychological traumas, among other things.

Here are some of the coolest things scientists have discovered about psychedelics over the years.

1. LSD can mitigate end-of-life anxiety.

The results of the first clinical study of the therapeutic use of LSD (lysergic acid diethylamide) in humans in more than 40 years were published in the peer-reviewed Journal of Nervous and Mental Disease in March. They show that LSD can promote statistically significant reductions in anxiety for people coming to terms with their own impending demise.
