Tissue damage and senescence provide critical signals for cellular reprogramming in vivo

Posted by in category: biotech/medical

More developments in senescent cell signalling published this month.

Differentiated cells in a culture dish can assume a new identity when manipulated to express four transcription factors. This “reprogramming” process has sparked interest because conceivably it could be harnessed as a therapeutic strategy for tissue regeneration. Mosteiro et al. used a mouse model to study the signals that promote cell reprogramming in vivo. They found that the factors that trigger reprogramming in vitro do the same in vivo; however, they also inflict cell damage. The damaged cells enter a state of senescence and begin secreting certain factors that promote reprogramming, including an inflammatory cytokine called interleukin-6. Thus, in the physiological setting, cell senescence may create a tissue context that favors reprogramming of neighboring cells.

SpaceX Wants to Surround Earth With an Internet Service That’s 200 Times Faster

Posted by in categories: Elon Musk, internet, satellites

SpaceX, the aerospace company founded by the Mars-hungry tech entrepreneur Elon Musk, just made a big move to enshroud the planet in high-speed internet coverage.

On November 15, the company filed a lengthy application with the Federal Communications Commission (FCC) to launch 4,425 satellites. (We first heard about the filing through the r/SpaceX community on Reddit.) That is a hell of a lot of satellites.

According to a database compiled by the Union of Concerned Scientists, there are 1,419 active satellites currently orbiting Earth.

China Invents Space GPS For Mars Expedition And Interplanetary Travel

Posted by in category: space travel

China launched a satellite this month that may be the key to a successful manned Mars mission and eventual colonization of the red planet beating out a similar NASA system scheduled to launch next year.

The world’s first X-ray navigation satellite acts like a GPS guidance system for spacecraft traveling beyond low Earth orbit and is intended to help China put rovers on the moon and Mars.

The X-ray Pulsar Navigation 1 (XPNAV) satellite measures radiation emitted by pulsars to pinpoint the exact location of a spacecraft, John Pye, manager of the Space Research Centre at the University of Leicester, told VICE News.

LIVING ROBOT with ‘HUMAN BRAIN’ close to creation as super AI computer around the corner

Posted by in categories: robotics/AI, singularity

Fast tracking to singularity. We will see an acceleration of Synbio technology in this space and once QC is more and more available in our infrastructure we will see more and more adoption due to performance and reduce risks.

COMPUTER scientists attempting to electronically replicate the human brain are close to creating a ‘living PC’.

The Membranes Covering The Brain Are Loaded With Neuronal Stem Cells

Posted by in categories: biotech/medical, neuroscience

For many years, scientists believed that our brains were unable to produce new neurons once we had been born, and that we all had to make do with the brain cells we started life with. Later, it became clear that new brain cells are in fact created in some key brain regions, replacing those that become damaged and protecting us from dementia. Now, researchers have discovered that the stem cells giving rise to these neurons originate in the membranes encasing the brain, known as the meninges.

Publishing their findings in the journal Cell Stem Cell, the authors claim that their discovery of this source of stem cells could one day lead to new treatments for brain damage or neurodegenerative disorders.

Most neurogenesis in the adult brain occurs in a region called the hippocampus, where the creation of new brain cells ensures our memories remain in working order as we age. The meninges penetrate the brain at every level, encapsulating a number of different regions, including the hippocampus.

The new frontier for drone warfare: Under the oceans

Posted by in categories: drones, military, robotics/AI

As unmanned aerial drones have become a critical part of modern warfare, the Pentagon is now looking to deploy autonomous robots underwater, patrolling the sea floor on what one top Navy official called an “Eisenhower highway network,” complete with rest stops where the drones could recharge.

Although still in the development stages, the technology has matured in recent years to be able to overcome the vast difficulties of operating underwater, a far more harsh environment than what aerial drones face in the sky.

Saltwater corrodes metal. Water pressure can be crushing at great depths. And communication is severely limited, so the vehicles must be able to navigate on their own without being remotely piloted.
