New findings from the Curiosity Rover’s samples have given scientists another look at distinct carbon signatures found on Mars.

NASA’s Curiosity Rover continues to send back new information about the Red Planet on a frequent basis. The latest discovery brings news of an interesting carbon signature that we didn’t expect to see on Mars. Following analyzations of rock samples returned by the rover, NASA announced that several of the samples are rich in a carbon type that we see on Earth, too. The signature, NASA claims, is most often associated with biological processes, which could give more credence to the possibility of life on Mars.

Of course, like many previous samples recovered from the Red Planet, these new ones continue to raise new questions. It’s worth noting that the existence of the carbon type on Mars isn’t necessarily proof of ancient life. A new study says that the signature could be proof of ancient life. However, it could also just be the result of an interaction between carbon dioxide and ultraviolet light. Additionally, it could be the remnants of carbon left behind after a major cosmic event that happened millions of years ago.

Learnings For Regenerative Morphogenesis, Astro-Biology And The Evolution Of Minds — Dr. Michael Levin, Tufts University, and Dr. Josh Bongard, University of Vermont.

Xenobots are living micro-robots, built from cells, designed and programmed by a computer (an evolutionary algorithm) and have been demonstrated to date in the laboratory to move towards a target, pick up a payload, heal themselves after being cut, and reproduce via a process called kinematic self-replication.

In addition to all of their future potential that has been mentioned in the press, including Xenobot applications for cleaning up radioactive wastes, collecting micro-plastics in the oceans, and even helping terraform planets, Xenobot research offers a completely new tool kit to help increase our understanding of how complex tissues/organs/body segments are cooperatively formed during the process of morphogenesis, how minds develop, and even offers glimpses of possibilities of what novel life forms we may encounter one day in the cosmos.

In the search for extraterrestrial intelligence (SETI), we’ve often looked for signs of intelligence, technology and communication that are similar to our own. But as astronomer and SETI trailblazer Jill Tarter points out, that approach means searching for detectable techno signatures, like radio transmissions, not searching for intelligence itself. At the moment scientists are considering whether artificial intelligence (AI) could help us search for alien intelligence in ways we haven’t even thought of yet.

As we think about extraterrestrial intelligence it’s helpful to remember humans are not the only intelligent life on Earth. For all we know, chimpanzees have culture and use tools, spiders process information with webs, cetaceans have dialects, crows understand analogies and beavers are great engineers. Non-human intelligence, language, culture and technology surround us to no end. Alien intelligence could look like an octopus, an ant, a dolphin or a machine or, on the other hand, be radically different from anything on Earth.

If you are a scientist, willing to share your science with curious teens, consider joining Lecturers Without Borders!

Established by three scientists, Luibov Tupikina, Athanasia Nikolau, and Clara Delphin Zemp, and high school teacher Mikhail Khotyakov, Lecturers Without Borders (LeWiBo) is an international volunteer grassroots organization that brings together enthusiastic science researchers and science-minded teens. LeWiBo founders noticed that scientists tend to travel a lot – for fieldwork, conferences, or lecturing – and realized scientists could be a great source of knowledge and inspiration to local schools. To this end, they asked scientists to volunteer for talks and workshops. The first lecture, delivered in Nepal in 2017 by two researchers, a mathematician and a climatologist, was a great success. In the next couple of years, LeWiBo volunteers presented at schools in Russia and Belarus; Indonesia and Uganda; India and Nepal. Then, the pandemic forced everything into the digital realm, bringing together scientists and schools across the globe. I met with two of LeWiBo’s co-founders, physicist Athanasia Nikolaou and math teacher Mikhail Khotyakov, as well as their coordinator, Anastasia Mityagina, to talk about their offerings and future plans.

Julia Brodsky: So, how many people volunteer for LeWiBo at this time?

Anastasia Mityagina: We have over 200 scientists in our database. This year alone, volunteers from India, Mozambique, Argentina, the United States, France, Egypt, Israel, Brazil, Ghana, Nigeria, Ethiopia, Botswana, Portugal, Croatia, Malaysia, Spain, Colombia, Italy, Germany, Greece, Denmark, Poland, the United Kingdom, Austria, Albania, Iran, Mexico, Russia, and Serbia joined us. Their areas of expertise vary widely, from informatics, education, and entrepreneurship, to physics, chemistry, space and planetary sciences, biotechnology, oceanography, viral ecology, water treatment, nanotechnology, artificial intelligence, astrobiology, neuroscience, and sustainability. We collaborate with hundreds of schools, education centers, and science camps for children in different parts of the world. In addition, our network includes more than 50 educational associations in 48 countries that help us reach out to approximately 8,000 schools worldwide.

“Here’s How Humans Might Beat Other Intelligent Life in a Science Fictional Space Race | Tor.com”

Suppose for the moment that one is a science fiction writer. Suppose further that one desires a universe in which intelligence is fairly common and interstellar travel is possible. Suppose that, for compelling plot reasons, one wants humans to be the first species to develop interstellar flight. What, then, could keep all those other beings confined to their home worlds?

Here are options, presented in order of internal to external.

The easiest method, of course, is that while our Hypothetical Aliens—Hypotheticals for short!—are just as bright as we are, a glance at human prehistory suggests that there is no particular reason to think we were fated to go down the technological path that we did. Sure, the last ten thousand years have seen breakneck technological development, but that’s just a minute portion of a long history. Anatomically modern humans date back 300,000 years. The last ten thousand years have been highly atypical even for our sort of human. Other human species appear to have come and gone without ever venturing out of the hunter-gatherer niche. Perhaps the development of agriculture was a wildly unlikely fluke.

In our first episode of John Michael Godier’s Event Horizon, we discuss the possibility of Alien civilizations moving to Galaxy Clusters to make the best use of mass and energy, why making copies of ourselves may be the key to interstellar travel and colonization, the habitability of planets around red dwarf stars such as Proxima Centauri, Black Holes, and so much more with our first guest Harvard Theoretical Physicist Dr. Avi Loeb, the Frank B. Baird Jr. Professor of Science at Harvard University.

How many black holes are out there in the Universe? This is one of the most relevant and pressing questions in modern astrophysics and cosmology. The intriguing issue has recently been addressed by the SISSA Ph.D. student Alex Sicilia, supervised by Prof. Andrea Lapi and Dr. Lumen Boco, together with other collaborators from SISSA and from other national and international institutions. In a first paper of a series just published in The Astrophysical Journal, the authors have investigated the demographics of stellar mass black holes, which are black holes with masses between a few to some hundred solar masses, that originated at the end of the life of massive stars. According to the new research, a remarkable amount around 1% of the overall ordinary (baryonic) matter of the Universe is locked up in stellar mass black holes. Astonishingly, the researchers have found that the number of black holes within the observable Universe (a sphere of diameter around 90 billions light years) at present time is about 40 trillions, 40 billion billions (i.e., about 40 × 1018, i.e. 4 followed by 19 zeros!).

A new method to calculate the number of black holes

As the authors of the research explain: This important result has been obtained thanks to an original approach which combines the state-of-the-art stellar and binary evolution code SEVN developed by SISSA researcher Dr. Mario Spera to empirical prescriptions for relevant physical properties of galaxies, especially the rate of star formation, the amount of stellar mass and the metallicity of the interstellar medium (which are all important elements to define the number and the masses of stellar black holes). Exploiting these crucial ingredients in a self-consistent approach, thanks to their new computation approach, the researchers have then derived the number of stellar black holes and their mass distribution across the whole history of the Universe.
