Australian researchers have identified two new mammals in the Land Down Under — both cousins of the doe-eyed flying marsupials known as greater gliders, according to a report.
A study published in Nature’s Scientific Reports journal found two new distinct and smaller species of gliders in northern and central Australia, outside of the marsupial’s known habitat in the country’s southern end, the Sydney Morning Herald reported.
“Australia’s biodiversity just got a lot richer,” Andrew Krockenberger, a professor at James Cook University and a co-author of the study, told the outlet. “It’s not every day that new mammals are confirmed, let alone two new mammals.”
If Facebook’s AI research objectives are successful, it may not be long before home assistants take on a whole new range of capabilities. Last week the company announced new work focused on advancing what it calls “embodied AI”: basically, a smart robot that will be able to move around your house to help you remember things, find things, and maybe even do things.
Robots That Hear, Home Assistants That See
In Facebook’s blog post about audio-visual navigation for embodied AI, the authors point out that most of today’s robots are “deaf”; they move through spaces based purely on visual perception. The company’s new research aims to train AI using both visual and audio data, letting smart robots detect and follow objects that make noise as well as use sounds to understand a physical space.
To mark the 20th anniversary of continuous habitation of the International Space Station, ESA commissioned two graphic artists to illustrate the Station from two perspectives. We spoke to the artists and asked them how they approached this challenge.
The International Space Station celebrates a huge milestone on 2 November 2020. For two decades, it has continuously hosted humans in space. Eighteen ESA astronauts have flown to the Station. Altogether, more than 240 crew members and visitors from 19 countries have visited the station and made it their temporary home.
A collaboration between five space agencies, the station has become a symbol of peaceful international cooperation. It represents the best of our space engineering capabilities as well as humankind’s pursuit of scientific knowledge and exploration.
“On Mars, it would occupy one of the maze of lava tubes which run beneath the Martian surface,” the architects explained.
Hugh Broughton Architects and Pearce+ are creating Martian House, an inflatable building in Bristol, England, that will explore what an extraterrestrial house for life on Mars could look like.
The house, a collaboration with local artists as part of the ongoing art project Building a Martian House, is set over two levels, with the lower level designed to be built below the ground of the red planet.
The upper level will be made from a gold inflatable formwork, which is being developed by specialists Inflate.
There are many options for living on Mars. 3D-printed ice habitats around the poles, building underground, etc. The technology is finally here.
This is part of the reason why the surface is so cold, ranging from −143 in the polar regions during winter and 35 °C (−226 to 95 °F) near the equator during midday in the summer. But because the air is so thin, a person standing on Mars (in the summer and at noon) would experience extreme cold anywhere above their ankles.
And then there’s the radiation, which is roughly 40 times higher than what humans are regularly exposed to here on Earth (worse, when a solar event occurs). There are also massive dust storms that can envelop the entire planet and block out all sunlight. Last, there’s Martian gravity, which is about 37% of what we experience here on Earth.
Space — The final frontier, and for Soviet cosmonaut, Sergei Krikalev, it nearly was his final frontier! Check out today’s new video where a soviet astronaut was on a space mission, meanwhile the USSR crumbled,… More making him the last citizen of the Soviet Union. How did Sergei finally get home, and what home would he be coming back to? Check out this epic new space story to find out!
NASA’s Stratospheric Observatory for Infrared Astronomy (SOFIA) discovered water on the sunlit surface of the Moon. This discovery indicates that water may be distributed across the lunar surface, and not limited to cold, shadowed places. This water was detected in Clavius Crater, yes the very same crater featured in the movie 2001 a Space Odyssey as the site of the lunar monolith. In reality this crater’s discovery my spur space exploration, development, and settlement. Find out how in this video.

In a recent study of the upper atmosphere of Venus, finding the chemical fingerprint of phosphine has led to speculation that it may be tied to airborne life high in the clouds of our sister planet [1]. We harbour similar suspicion of microbial life on Mars [2], Saturn’s moon Enceledus [3], and Europa, the icy Galilean of the Jovian system [4]. The dwarf planet Ceres of the asteroid belt could be added to that list also, with recent evidence of oceanic water [5], while more exotic variations of life may exist on Titan, which is known to be teeming with organic materials [6]. Should we be more wary of our Solar System as an environment to explore, and the potential of pathogens we may encounter?
If one rewinds 500 years, to when exploration of new worlds involved sailing the oceans, the discovery of the Americas introduced viruses which decimated the native population at that time [7]. That in itself was far from a unique event in history, of course. There have been many occurrences throughout history where travel between distant lands has resulted in the introduction of devastating plagues to one population or the other — not least the Black Death, which arrived in Europe from commercial travel with Asia in the 1300s [8]. Meanwhile, 2020 has reminded us how a novel virus can prove virtually unstoppable from spreading worldwide in a matter of months and reaching pandemic level, once introduced to our now interconnected world [9].
Indeed when the first astronauts returned from the Moon in the 60s, they had to undergo weeks of quarantine as a precaution against introducing a lunar pathogen to Earth [10]. We now know the Moon to be a sterile world, but this should not give us a false sense of security when visiting and returning from other worlds, which are far more likely to harbour microbial life. It is quite plausible to consider that any microbes which have evolved to survive in the harsh environments on other worlds could multiply out of control if introduced to a more fertile environment on Earth. The likelihood of any such foreign microbes being capable of becoming infectious pathogens to our species is difficult to measure, but one could still cause problems regardless, by undermining Earth’s ecosystem in competing with native microbial life as a runaway invasive species.
