Orion Bar region investigated in detail

Posted by in categories: evolution, space

Using spacecraft and ground-based facilities, Russian astronomers have inspected the Orion Bar photodissociation region, focusing on the mid-infrared emission from this source. Results of the study could help astronomers to better understand the evolution of polycyclic aromatic hydrocarbons in space. The research was published November 10 on arXiv.org.

At a distance of about 1,300 away, the Orion Nebula is the nearest of massive star formation to Earth, with a complex and extensive gas structure. It hosts the so-called “Orion Bar”—a ridge-like feature of gas and dust formed by the intense radiation from nearby, hot, young stars, which appears to be shaped like a bar.

The Orion Bar is a photodissociation region or photon-dominated region (PDR). In general, PDRs are regions in the interstellar medium (ISM) at the interface between hot ionized gas and cool molecular gas that are energetically dominated by non-ionizing ultraviolet photons.

Yuval Noah Harari: The 2021 60 Minutes interview

Posted by in category: evolution

The bestselling author and historian offers his predictions on how technology will alter the evolution of humans and change society. Anderson Cooper reports.

“60 Minutes” is the most successful television broadcast in history. Offering hard-hitting investigative reports, interviews, feature segments and profiles of people in the news, the broadcast began in 1968 and is still a hit, over 50 seasons later, regularly making Nielsen’s Top 10.

Embodied intelligence via learning and evolution

Posted by in categories: evolution, physics

The authors present a high-resolution palaeomagnetic record for a Late Cretaceous limestone in Italy. They claim that their record robustly shows a ~12° true polar wander oscillation between 86 and 78 Ma, with the greatest excursion at 84–82 Ma.


The authors propose a new framework, deep evolutionary reinforcement learning, evolves agents with diverse morphologies to learn hard locomotion and manipulation tasks in complex environments, and reveals insights into relations between environmental physics, embodied intelligence, and the evolution of rapid learning.

Why extraterrestrial intelligence is more likely to be artificial than biological

Posted by in categories: alien life, evolution

It’s Time to welcome our Space Brothers.


Is there intelligent life elsewhere in the universe? It’s a question that has been debated for centuries, if not millenia. But it is only recently that we’ve had an actual chance of finding out, with initiatives such as Seti (Search for Extraterrestrial Intelligence) using radio telescopes to actively listen for radio messages from alien civilisations.

What should we expect to detect if these searches succeed? My suspicion is that it is very unlikely to be little green men—something I speculated about at a talk at a Breakthrough Listen (a Seti project) conference.

Living brain donors are helping us better understand our own neurons — including those potentially linked to Alzheimer’s disease

Posted by in categories: biotech/medical, evolution, neuroscience

Live human brain tissue — generously donated by brain surgery patients with epilepsy or tumors — is yielding incredible #neuroscience insights. A study on cells… See More.


As part of an international effort to map cell types in the brain, scientists identified increased diversity of neurons in regions of the human brain that expanded during our evolution.

Launching Lucy, NASA’s First Mission to the Trojan Asteroids

Posted by in categories: evolution, space

On Oct. 16 2021, our Lucy spacecraft will begin its journey to visit a record-breaking number of asteroids. The 12-year mission starts from NASA’s Kennedy Space Center where it’ll launch aboard a United Launch Alliance Atlas V 401 rocket. From there, Lucy will be the first spacecraft to visit a record number of destinations in independent orbits around the sun – one main belt asteroid and seven of Jupiter’s Trojan Asteroids. Like the mission’s namesake – the fossilized human ancestor, “Lucy,” whose skeleton provided unique insight into humanity’s evolution – Lucy will revolutionize our knowledge of planetary origins and the formation of the solar system.

Lucy’s first launch attempt in its 21-day launch window is scheduled for 5:34 a.m. EDT on Oct. 16. Launch coverage starts at 5 a.m. EDT on NASA TV, the NASA app, and @NASA social media. Be a part of Lucy’s historic launch day by using the hashtag #LucyMission!

Scientists Finally Know Why Wisdom Teeth Only Emerge When We’re Basically Adults

Posted by in category: evolution

We humans like to take our time when it comes to growing up. Among the great apes, only chimpanzees come close to stretching out the years between key developmental milestones.

But even chimps are ready to get crunching with a full set of chompers by the time they’re sexually mature. Homo sapiens don’t grow their last few teeth until they’re nearly out of the teenage years.

This mystery of the molars is a tricky one to solve, in spite of their emergence playing such a critical role in tracking shifts in our evolution. But researchers from the University of Arizona in the US now think they might have cracked it.
