NASA and SpaceX explore using Dragon to send Hubble back to its initial position

Posted by in category: space travel

NASA and SpaceX are undertaking a feasibility study.

The Hubble Space Telescope could one day be serviced by a private SpaceX spacecraft called Dragon, according to an article published by Space.com


Jensen further added that a Dragon Hubble mission wouldn’t necessarily need to be crewed. The study might point the way to an uncrewed mission with Dragon or even a different aircraft.

What is ‘dark data’? How digital information is quietly sapping energy

Posted by in categories: business, computing, finance, internet, space

Digitalization generated 4 percent of the total greenhouse emissions in 2020.

More than half of the digital data firms generate is collected, processed, and stored for single-use purposes. Often, it is never re-used. This could be your multiple near-identical images held on Google Photos or iCloud, a business’s outdated spreadsheets that will never be used again, or data from internet of things sensors that have no purpose.

This “dark data” is anchored to the real world by the energy it requires. Even data that is stored and never used again takes up space on servers — typically huge banks of computers in warehouses. Those computers and those warehouses all use lots of electricity.

The Cybertruck will also be a boat, says Elon Musk

Posted by in categories: Elon Musk, sustainability, transportation

He made the announcement as usual over Twitter.

Over the years, we have watched with excitement as Tesla CEO Elon Musk has revealed more and more details about the Cybertruck. On Thursday, he took to Twitter to share one more feature of the truck: it will be waterproof enough to briefly serve as a boat.

Bioinspired robots walk, swim, slither and fly

Such robotic schools could be tasked with locating and recording data on coral reefs to help researchers to study the reefs’ health over time. Just as living fish in a school might engage in different behaviours simultaneously — some mating, some caring for young, others finding food — but suddenly move as one when a predator approaches, robotic fish would have to perform individual tasks while communicating to each other when it’s time to do something different.

“The majority of what my lab really looks at is the coordination techniques — what kinds of algorithms have evolved in nature to make systems work well together?” she says.

Many roboticists are looking to biology for inspiration in robot design, particularly in the area of locomotion. Although big industrial robots in vehicle factories, for instance, remain anchored in place, other robots will be more useful if they can move through the world, performing different tasks and coordinating their behaviour.

Chernobyl black frogs reveal evolution in action

Posted by in categories: biological, evolution, genetics, nuclear energy

The accident at reactor four of the Chernobyl Nuclear Power Plant in 1986 generated the largest release of radioactive material into the environment in human history. The impact of the acute exposure to high doses of radiation was severe for the environment and the human population. But more than three decades after the accident, Chernobyl has become one of the largest nature reserves in Europe. A diverse range of endangered species finds refuge there today, including bears, wolves, and lynxes.

Radiation can damage the genetic material of living organisms and generate undesirable mutations. However, one of the most interesting research topics in Chernobyl is trying to detect if some species are actually adapting to live with radiation. As with other pollutants, radiation could be a very strong selective factor, favoring organisms with mechanisms that increase their survival in areas contaminated with radioactive substances.

Scientists Discover That Chromosomes Are Fluid

Posted by in category: biotech/medical

Researchers from CNRS, the Curie Institute, and Sorbonne University have successfully physically acted on chromosomes in live cells for the first time. They found that, outside of cell division phases, chromosomes are actually very fluid—almost liquid—by subjecting to different forces using magnets. The study was recently published in the prestigious journal Science.

When they are not in their division phases, chromosomes are fluid, though not quite liquid. This discovery was made possible by the first-ever direct mechanical manipulation of chromosomes in the nucleus of live cells.

Previously, chromosomes, which are extraordinarily long DNA.

Researchers came up with a new method to make the brain organoid “Brainier”

Posted by in category: neuroscience

https://www.eurekalert.org/multimedia/959965

Researchers have been growing brain organoids for several years, but not all organoids are created the same. It can vary from lab to lab — and even from batch to batch — which means that a finding made in one organoid may not hold true in another.

Newly recognised species of sloth has a head like a coconut

Posted by in category: genetics

The world has one more sloth species in it than previously thought. Maned sloths live in a small belt of forest in Brazil and an analysis now suggests those in the south are a different species from those found farther north.

Three-toed sloths were conventionally thought to be divided into four species. One — the maned sloth (Bradypus torquatus) — sports a thatch of coarse, brown hair, making the head resemble a husked coconut.


Maned sloths were thought to be one species but a genetic and physical analysis suggests there are actually two.

This New Liquid Is Magnetic, and Mesmerizing

Posted by in categories: computing, particle physics

Circa 2019


Lodestone, a naturally-occurring iron oxide, was the first persistently magnetic material known to humans. The Han Chinese used it for divining boards 2,200 years ago; ancient Greeks puzzled over why iron was attracted to it; and, Arab merchants placed it in bowls of water to watch the magnet point the way to Mecca. In modern times, scientists have used magnets to read and record data on hard drives and form detailed images of bones, cells and even atoms.

Throughout this history, one thing has remained constant: Our magnets have been made from solid materials. But what if scientists could make magnetic devices out of liquids?
