Elon Musk’s Neuralink startup raises $39 MILLION as it seeks to develop tech that will connect the human brain with computers…

An Elon Musk-backed startup looking to connect human brains to computers has raised most of its $51 million funding target. According to a report Neuralink has raised $39 million.

Viruses are masterful invaders. They cannibalize host cells by injecting their genetic material, often making thousands of copies of themselves in a single cell to ensure their replication and survival.

Some RNA viruses insert their genetic material as a single piece, while others chop it up into pieces. The latter are aptly named segmented viruses.

Such segmented RNA viruses—including several that cause human diseases like influenza—have been a longstanding enigma to researchers: How do they accomplish the precise copying and insertion of each segment? How do they ensure that individual segments are all copied by the same enzyme while ensuring that each segment can make different amounts of RNA? Such exquisite regulation is critical to make the correct levels of the viral proteins necessary for successful replication.

Huge plastic waste dumps float in the Oceans bigger than continents. Some 10% of world’s plastic waste finds its way into the sea and ends up in the central regions where slow moving circular currents trap debris into one large constantly moving mass of plastic. This is slowly being broken down into a plastic dust that marine wildlife mistake for food. Small fish consume tiny bits of plastic as if they were normal plankton. Those fish are then consumed by larger species and the plastic contamination moves up the food chain. Over a million seabirds, as well as more than 100 thousand marine mammals, die every year from ingesting plastic debris. Some researchers estimate that there are over six kilos of plastic for every kilo of naturally occurring plankton in the Pacific plastic waste dump.

Dead seabirds having mistaken plastics for food, have been found with discarded plastic lighters, water bottle caps and scraps of plastic bags in their stomachs. / Oceanic gyres: the circular movement of the ocean waters concentrates the plastic in the centre of the oceans.

But maybe things are not as bad as it looks: scientists working on the pollution saw that it did not grow in 22 years, even if the plastic production grew fourfold. An organism may be eating plastic in the ocean, but whether the bug is green or mean remains to be seen.

Scientists might have found an early detection method for some forms of dementia, according to new research by the University of Arizona and the University of Toronto’s Baycrest Health Sciences Centre.

According to the study published in the journal Neuropsychologia last month, patients with a rare neurodegenerative brain disorder called Primary Progressive Aphasia, or PPA, show abnormalities in brain function in areas that look structurally normal on an MRI scan.

“We wanted to study how degeneration affects function of the brain,” said Aneta Kielar, the study’s lead author and assistant professor in the UA Department of Speech, Language and Hearing Sciences.

Planes, Drones, and AI Machines

But going from Mach 2 to Mach 5 is not an easy undertaking. Hermeus is hoping to pull from existing technologies to make its insanely fast passenger plane a reality, including titanium materials and cutting edge rocketry.

It’s impossible to tell what the future of air travel will look like. If supersonic airplanes aren’t it, SpaceX founder Elon Musk has pushed for the idea that we’ll go between Earthly destinations in rockets that can technically take us to Mars.

Circa 2018

Lockheed Martin has won a nearly quarter-billion dollar NASA contract to develop a plane capable of supersonic speed without creating the deafening sonic boom that comes with breaking the sound barrier.

The cost-plus NASA contract, valued at $247.5 million, will allow the defense contractor’s secretive Skunk Works division to continue development of Lockheed Martin’s Quiet Supersonic Technology (or QueSST) aircraft. This is “NASA’s first X-plane in a generation,” a Lockheed Martin spokesperson told CNBC on Tuesday.

It’s very easy to forget that complex life on Earth almost missed the boat entirely. As the Sun’s luminosity gradually increases, the oceans will boil away, and the planet will no longer be in the habitable zone for life as we know it. Okay, we likely have a billion years before this happens—by which point our species will probably have destroyed itself or moved away from Earth—but Earth itself is 4.5 billion years old or so, and eukaryotic life only started to diversify 800 million or so years ago, at the end of the “boring billion.”

In other words, life seems to have arisen around four billion years ago, shortly after Earth formed, but then a few billion years passed before anything complex evolved. Another few hundred million years of bacteria, algae, and microbes sliding around in the anoxic sludge of the boring billion, and intelligent life might never have evolved at all.

Unraveling the geologic mysteries of the boring billion, and why it ended when it did, is a complex scientific question. Different parts of the earth system, including plate tectonics, the atmosphere, and the biosphere of simple lichens and cyanobacteria interacted to eventually produce the conditions for life to diversify, flourish, and grow more complex. But it is generally accepted that simple cyanobacteria (single-celled organisms that can produce oxygen through photosynthesis) were key players in providing Earth’s atmosphere and oceans with oxygen, which then allowed complex life to flourish.
