The Early Universe Explained by Neil deGrasse Tyson

Posted by in categories: cosmology, information science, mathematics, neuroscience, nuclear energy, particle physics, singularity

Neil deGrasse Tyson explains the early state of our Universe. At the beginning of the universe, ordinary space and time developed out of a primeval state, where all matter and energy of the entire visible universe was contained in a hot, dense point called a gravitational singularity. A billionth the size of a nuclear particle.

While we can not imagine the entirety of the visible universe being a billion times smaller than a nuclear particle, that shouldn’t deter us from wondering about the early state of our universe. However, dealing with such extreme scales is immensely counter-intuitive and our evolved brains and senses have no capacity to grasp the depths of reality in the beginning of cosmic time. Therefore, scientists develop mathematical frameworks to describe the early universe.

The Kerbal Effect

Posted by in categories: education, space travel

Kerbal Space Program has now been out for a full 10 years, progressing alongside the space industry and the various people that operate within it. This documentary-style video takes a look at the people that have been influenced, inspired, and introduced to the wonder of space exploration by this bizarre game about little green beings, created by a small group of developers in Mexico City.

We want to thank you, the community, for helping us turn KSP into the launchpad for the next generation of space explorers!

CRISPR injected into the blood treats a genetic disease for first time

Posted by in categories: biotech/medical, genetics

Now, in a medical first, researchers have injected a CRISPR drug into the blood of people born with a disease that causes fatal nerve and heart disease and shown that in three of them it nearly shut off production of toxic protein by their livers.


Novel treatment using messenger RNA sharply cuts production of mutant liver protein, although it’s too early to show patients with rare condition benefit.

‘It’s a wow!’: New CRISPR gene-editing success holds promise for treating many genetic diseases with a single dose

Posted by in categories: biotech/medical, genetics, life extension, nanotechnology

👏😄We are rapidly approaching — from multiple directions of attack (pharmaceutical, nanotechnology, gene manipulation, etc) — the end of all forms of cancer, inherited diseases, even aging itself. It’s a great time to be alive IF you can live long enough to live forever(ish)! Which makes EVERY death that occurs in the meantime to be all the more of a punch to the gut and slap to the face. PARTICULARLY the 600 000 + people here in the US alone! It’s also another reason t… See More.


If the gene-editing tool CRISPR/Cas9 continues to show such promise it will herald a new era for the treatment of many genetic diseases.

Are humans on the brink of achieving immortality?

Posted by in categories: biotech/medical, life extension

In August last year, Unity released interim results showing that its drug was probably ineffective in treating study patients suffering from osteoarthritis.

Its stock price plummeted as a consequence, but Dr de Grey remains hopeful that “soon we might have drugs that actively cause these cells to die”.

While Dr de Grey is excited to see much of the life extension research he helped develop come to fruition, some thinkers are raising concerns about the implications of an extended human lifespan.

Babies Can See Things That Adults Cannot

Posted by in category: neuroscience

The results of the study demonstrated that the mechanisms for visual perception change drastically in the second half of the first year of life, from the bottom-up system to the system incorporating top-down processing.


Summary: Study reveals very young infants can perceive objects that older infants, children, and adults can not see due to a phenomenon called visual backward masking.

Are MXenes the future of nanotechnology?

Posted by in categories: biotech/medical, nanotechnology

Artificial kidneys, powerful batteries and efficient water purification are some of the future applications of a group of ultrathin materials known as MXenes. This opinion is expressed in an article in the journal Science, whose authors include one from Linköping University.

Materials that have a cross-section as thin as one or a few layers of atoms possess unusual properties due to their thickness. These properties may be , or an ability to withstand heat, giving a great potential for use in future technology. The most well-known material is graphene, and the hunt for other ultrathin materials, also known as two-dimensional materials, has increased in intensity since its discovery.

Graphene and many other two-dimensional materials are either semiconductors, semimetals or polarized insulators. The lack of an ultrathin metal conductor is an obstacle in the development of components based exclusively on two-dimensional materials.

In Extraordinary Experiment, Physicists Bring Human-Scale Object to Near Standstill, Reaching a Quantum State

Posted by in categories: particle physics, quantum physics

The results open possibilities for studying gravity’s effects on relatively large objects in quantum states.

To the human eye, most stationary objects appear to be just that — still, and completely at rest. Yet if we were handed a quantum lens, allowing us to see objects at the scale of individual atoms, what was an apple sitting idly on our desk would appear as a teeming collection of vibrating particles, very much in motion.

In the last few decades, physicists have found ways to super-cool objects so that their atoms are at a near standstill, or in their “motional ground state.” To date, physicists have wrestled small objects such as clouds of millions of atoms, or nanogram-scale objects, into such pure quantum states.
