Finding definitive evidence for past primitive life in ancient Mars rock and soil samples may be well-nigh impossible, renowned geologist and astrobiologist Frances Westall told me at the recent Europlanet Science Congress (EPSC) in Granada, Spain. And she should know. Westall is someone who still claims the discovery of Earth’s oldest-known microfossils, dating back some 3.45-billion-years ago.

But it’s hard enough to identify primitive microfossils in Earth’s oldest rocks, much less from robotic samples taken on Mars. Thus, if we have a hard time identifying past life on Earth, what hope do we have of doing it with Mars samples?

“I think it’s going to be really difficult,” said Westall, a researcher at France’s Center for Molecular Biophysics in Orleans. “I can tell you, there’s going to be a lot of arguments about it.”

Capturing combustion on a large scale is now possible.

The first cross-sectional photos of carbon dioxide in a jet engine exhaust plume were taken by researchers using brand-new near-infrared light imaging technology.

The research was published in Applied Optics’ 28th issue.

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.

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 This could be your multiple near-identical images held on Google Photos or iCloud, a business’s outdated spreadsheets that will never be used again, or data from internet of things sensors that have no purpose.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.

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.

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.

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.

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.
