Biology / This Is How Humans Will Become...
Last post by Unbeliever - April 10, 2019, 01:58:34 pm
QuoteIt's not known exactly when us humans began to imagine being able to live forever, but it's probably been thought about for thousands of years since getting old comes with a whole list of problems associated with it. The ancient Greek poet Homer called old age 'loathsome, and the well-known Shakespeare termed old age as a 'hideous winter'.

There are many scientists and researchers who believe that soon discoveries will be made that lead to immortality and that maybe even stem cell research could reverse the effects of aging since it has great potential. Believe it or not, it's not known exactly why we age, it just happens and it's a part of life. Researchers are still trying to understand what actually causes us to grow old and wither away and have looked at aging as if it were a disease.
But is it possible to achieve immortality?

There are many scientists who say that it's just a matter of time. In fact, the tech giant Google says that we will probably find out the secret to eternal life by the year 2029. This is the time when its estimated that Nano-bots will be created that will be able to swim through our bodies and fight disease. Even more unbelievable is that Ray Kurzweil, who is Google's director of engineering, says that medical advancements and technology will advance so much in the next 10 years that we may see humans being given the option to live forever.

It's a pretty bold statement unless you understand the concept of medical Nano-bots. The microscopic bots could one day be used as drug capsules that directly target the disease and deliver the cure without affecting the entire body. Some scientists claim that eventually, we will be able to inject tiny nanoscale machines into our bodies that act like tiny pharmaceutical labs. These tiny robots would be able to detect a problem inside of your body, process your body's natural enzymes and proteins into a drug, and then deliver it to the problem spot. Imagine never being sick again.

Nanotechnology is already capable of some incredible things.
At the same time, there are some scientists that say that it's impossible to biologically live forever because our bodies would age no matter what. Research suggests that by solving one problem the human body ends up with another. There is a normal cell cycle in our body and if good cells are boosted, then cancer cells have a better chance to grow and even more violently.

Well even if they are, there are other ways to become immortal.
Cryonics is something that has been around for decades and is the science of freezing the body of a person using ultra-cold temperatures stopping decay and putting everything on hold. No, it's not science fiction and shouldn't be confused with cryosleep you see in the movies.

And for the record for those who are curious, the first human ever frozen by cryonics was Dr. James Bedford, who passed away in 1967 and is still in his cryonic chamber after 50 years.
The big question one needs to ask themselves is 'do I really want to live forever?' Imagine the things that you would be able to accomplish if you could live as long as you wanted to. Of course, there is that whole 'afterlife' thing that a lot of people believe in. What if there is some existence when we leave our bodies and we don't want to come back?

Some of you might think that it will be impossible to bring a frozen person back to life. However, some cool technology has come from the science of cryogenics. Some doctors have come up with a procedure which removes all the blood from a wounded person's body and replaces it with a really cold saline solution which drops the bodies temperature to around 50 degrees Fahrenheit.

It is an absolutely fascinating thing that all of us will eventually experience what happens after we leave this Earth. Maybe there is some kind of glorious afterlife where only our spirit can live, or even perhaps scarier, maybe when we pass away it's as if we simply flipped off the light switch.

There are a lot of questions when it comes down to being immortal. If you could suddenly live forever, have your brain moved into a robot, or upload your consciousness into a computer.... Would you do this? What about your family, and your friends? What if they weren't coming along?

Astronomy/Cosmology / First Images of Black Holes!
Last post by Unbeliever - April 10, 2019, 01:06:35 pm

QuoteThe Event Horizon Telescope Collaboration observed the supermassive black holes at the center of M87 and our Milky Way galaxy (SgrA*) finding the dark central shadow in accordance with General Relativity, further demonstrating the power of this 100 year-old theory.

General Science / This Is What Will Happen By 20...
Last post by Unbeliever - April 09, 2019, 02:52:08 pm

QuoteMovies and television are constantly making predictions about how our world will change in the near future. And while they may often be comically wrong, like everyone zooming around on hoverboards in Back to the Future, we're going to be taking a look of our own. The truth is that since technology and humanity's capabilities have advanced exponentially within the last few decades, it's difficult to tell what our world will be like by 2030. With how our world is today the possibilities for science and technology are boundless, so what can we expect before the year 2030?

Astronomy/Cosmology / Galactic Center 360-degree Vis...
Last post by Unbeliever - April 08, 2019, 04:26:23 pm


QuoteA new immersive, 360-degree, ultra-high-definition visualization allows viewers to view the center of our Galaxy as if they were sitting in the position of the Milky Way's supermassive black hole (Sgr A*). By combining supercomputer simulations with Chandra data, the visualization shows the effects of dozens of massive stellar giants with fierce winds blowing off their surfaces in the region covering a few light years surrounding Sgr A*. Blue and cyan represent X-ray emission from hot gas with temperatures of tens of millions of degrees, while the red emission shows ultraviolet emission from moderately dense regions of cooler gas with temperatures of tens of thousands of degrees, and yellow shows the cooler gas with the highest densities.

Biology / DNA Doesn’t Look Like What You...
Last post by Unbeliever - April 08, 2019, 12:34:29 pm

QuoteBiology textbooks are full of drawings of DNA, but none of those show what DNA actually looks like. Sure, they're good models for understanding how DNA works, but inside of real cells, it's a whole lot more interesting. Learn why we can't look directly at DNA, and find out how DNA is actually packed inside cells.

QuoteThe hunt for dark matter is still on, and the candidates for it could be primordial black holes as massive as Earth, or axions, as tiny as the smallest subatomic particles in existence!
