A new method to synchronize devices on Earth makes use of cosmic rays

Posted by in category: space

Various technologies, networks and institutions benefit from or require accurate time keeping to synchronize their activities. Current ways of synchronizing time have some drawbacks that a new proposed method seeks to address. The cosmic time synchronizer works by synchronizing devices around cosmic ray events detected by those devices. This could bring accurate timing abilities to remote sensing stations, or even underwater, places that other methods cannot serve. Early tests show promise, but the real challenge may lie in the adoption of this new technique.

Humanity is intimately connected with the idea of time. Historically, we used the cosmos itself—stars, the sun, and the moon—to measure time and coordinate our activities. It’s fitting, then, that researchers are looking out to the cosmos again to further develop our ability to keep time. Professor Hiroyuki Tanaka from Muographix at the University of Tokyo devised and tested a way to synchronize multiple devices, so they agree upon the time, that makes use of from deep space. Appropriately, it’s called cosmic time synchronization (CTS).

“It’s relatively easy to keep time accurately these days. For example, have been doing this for decades now,” said Tanaka. “However, these are large and expensive devices that are very easy to disrupt. This is one reason I have been working on an improved way to keep time. The other is that, related to time measurement, position measurement could also be made better. So really, CTS is a precursor to a potential replacement for GPS, but that’s still a little further down the line.”

Retinal Cell Map Could Advance Precise Therapies for Blinding Diseases

Posted by in categories: biotech/medical, health, robotics/AI

Researchers have identified distinct differences among the cells comprising a tissue in the retina that is vital to human visual perception. The scientists from the National Eye Institute (NEI) discovered five subpopulations of retinal pigment epithelium (RPE)—a layer of tissue that nourishes and supports the retina’s light-sensing photoreceptors. Using artificial intelligence, the researchers analyzed images of RPE at single-cell resolution to create a reference map that locates each subpopulation within the eye. A report on the research published in Proceedings of the National Academy of Sciences.

“These results provide a first-of-its-kind framework for understanding different RPE cell subpopulations and their vulnerability to retinal diseases, and for developing targeted therapies to treat them,” said Michael F. Chiang, M.D., director of the NEI, part of the National Institutes of Health.

“The findings will help us develop more precise cell and gene therapies for specific degenerative eye diseases,” said the study’s lead investigator, Kapil Bharti, Ph.D., who directs the NEI Ocular and Stem Cell Translational Research Section.

See the grand design of spiral galaxy M99 in Hubble image

Posted by in category: cosmology

The swirling spiral of the elegant galaxy M99 is on display in this week’s image from the Hubble Space Telescope. As a prototypical spiral galaxy, like our Milky Way, M99 has the classical rotating disk of stars, gas, and dust, which is concentrated and bright in the center and reaches out into space with spiral arms. But his particular galaxy isn’t just any spiral galaxy — it is a “grand design” spiral galaxy, a classification given to the neatest and most orderly spiral galaxies whose arms are particularly prominent and well-defined.

The galaxy M99 is located in the constellation of Coma Berenices and is around 42 million light-years from Earth. As well as being visually stunning, this galaxy is an interesting target of research and has been imaged by Hubble’s Wide Field Camera 3 instrument twice, for two different research projects.

The first project M99 was observed for is one which looked at the difference between two types of explosions that can occur at the end of a star’s life: Novae and supernovae. Supernovae are the more dramatic, famous events, in which massive stars run out of fuel and explode in huge, bright events which can send out shockwaves and leave behind distinctive remnants. The less famous novae are dimmer events that happen when white dwarfs in a binary system with a larger star suck off layers of matter from that star’s outer shell.

Does Earth Have a Mind and Agency of Its Own?

Posted by in categories: biotech/medical, evolution, neuroscience

Does our planet have a mind and agency of its own? This is one of the main questions philosopher and mystic Oberon Zell illuminates in his latest masterpiece GaeaGenesis: Conception and Birth of the Living Earth. Just as we don’t see a bacterium with a naked eye, we don’t quite seem to have an innate ability to perceive the Gaian mind with a “naked” brain. As Dr. Ralph Metzner, Professor Emeritus of California Institute of Integral Studies and Founder-President of The Green Earth Foundation, writes: “Oberon Zell was the first person to conceive and publish the biological and metaphysical foundations of what has become known as the ‘Gaia Theory’ — the unified body and emergent soul of the living Earth… For over 50 years Oberon has been writing and lecturing on Gaian consciousness, and it is high time that he put it all together into a book!” And, indeed, he did.

The newly-released book takes the idea beyond the metaphorical realm postulated by James Lovelock in his “Gaia Hypothesis” and posits that the entire evolution of life on Earth is the literal embryology of a single vast living being — one replicating continuum of DNA and protoplasm. This distinction has significant implications for the subject of this book: The proposition that Mother Earth is a living, sentient being with a “soul” that humans can perceive if they are aware enough to sense it. In essence, the living beings that populate the Earth are cells within a greater macro-organism.

Here’s one of the revelatory passages from the book: To better understand the planet as a living system, we need to go beyond the time scales of human life to the planet’s own time scale, vastly greater than our own. Looked at in this way, the rhythm of day and night might be the pulse of the planet, one full cycle of every hundred thousand human heartbeats. Speeding up time appropriately, we would see the atmosphere and ocean currents swirling round the planet, circulating nutrients and carrying away waste products, much as the blood circulates nutrients and carries away waste in our own bodies.

A portable wind turbine that fits in your backpack? Yes please

Posted by in categories: mobile phones, sustainability

Canadian company Aurea has developed a portable wind turbine that fits in your backpack. Called Shine, it weighs just three pounds, it’s about the size of a water bottle, and it can charge any USB device, or up to four phones (though not at the same time). The turbine is shaped a bit like a mini Zeppelin. It features three gently curved blades that fold out like flower petals and a collapsible tripod that is stored inside. The product launched on Kickstarter last year and on Indigogo last week. It has raised over $270,000 so far and will be shipping in a matter of months–just in time for camping season.

Humans have been harnessing the wind for centuries, but it has always required massive infrastructure, be it windmills or wind turbines. In recent years, engineers and designers alike have taken it upon themselves to reinvent the technology by playing with scale and form (think wind turbines integrated into walls or giant grids made of tiny turbines). But Aurea’s founders had a different goal in mind: Make wind power portable.

Shine can be used during a blackout at home, and serve anyone who needs access to energy while not attached to the grid. But its most likely users are going to be campers, RVers, and nomads, making weight a crucial factor. “People said, ‘We won’t carry it if it weighs more than three pounds,’” says Cat Adaley, a mechanical engineer who founded Aurea in 2017 and developed Shine with entrepreneur Rachel Carr. “Every design feature was weighed.” (The battery makes up a third of the weight, and the turbine is made of polycarbonate reinforced plastic with a glass composite; the tripod is aluminum.) All of this helped the founders create a portable turbine that has the highest power to weight ratio of any renewable energy at this scale, Adaley says.

Ancient Cave Art in Alabama May Be The Largest Ever Found in North America

Posted by in categories: biotech/medical, evolution

New details of our past are coming to light, hiding in the nooks and crannies of the world, as we refine our techniques to go looking for them. Most lauded is the reconstruction of the evolution of humanity since our African origins around 300,000 years ago, by analyzing our living and fossil DNA.

Replete with the ghosts of African and Eurasian populations of the deep past, these have been resurrected only through the ability of science to reach into the world of the minuscule by studying biomolecules.

Now, digital analysis of rock surfaces reveals how other ghosts of the deep past – this time from almost 2,000 years ago in North America – have been coaxed into the light.
