Saturn’s icy moon hosts vital life source, key molecule, reveals NASA

Posted by in categories: chemistry, energy, space

NASA’s Cassini probe has uncovered compelling evidence hinting at the potential existence of life on Saturn’s icy moon Enceladus.


Interestingly, a detailed review of Cassini’s data has revealed that the subsurface ocean hidden beneath the moon’s frozen surface is a rich source of chemical energy.

This disclosure strengthens the case for exploring the possibility of life within the ocean of this frozen celestial body.

Physicist Discovers ‘Paradox-Free’ Time Travel Is Theoretically Possible

Posted by in categories: physics, space, time travel

No one has yet managed to travel through time – at least to our knowledge – but the question of whether or not such a feat would be theoretically possible continues to fascinate scientists.

As movies such as The Terminator, Donnie Darko, Back to the Future and many others show, moving around in time creates a lot of problems for the fundamental rules of the Universe: if you go back in time and stop your parents from meeting, for instance, how can you possibly exist in order to go back in time in the first place?

It’s a monumental head-scratcher known as the ‘grandfather paradox’, but a few years ago physics student Germain Tobar, from the University of Queensland in Australia, worked out how to “square the numbers” to make time travel viable without the paradoxes.

If alien life is artificially intelligent, it may be stranger than we can imagine

Posted by in categories: alien life, robotics/AI

We’ve long assumed that aliens will be like us, but there’s every reason to think they are instead a form of unfathomable AI, says the UK astronomer royal Lord Martin Rees.

NASA gives Blue Origin $35 million to turn moon dust into solar cells

Posted by in categories: solar power, space travel, sustainability

NASA has awarded Blue Origin a $35 million contract to further develop a technology that creates solar cells out of lunar regolith — the dust and crushed rock blanketing the moon’s surface.

“[W]e’re inspired and humbled to receive this investment from NASA to advance our innovation,” said Pat Remias, VP of Blue Origin’s Capabilities Directorate. “First we return humans to the moon, then we start to ‘live off the land.’”

Moon or bust: NASA plans to send astronauts to the moon again as soon as 2025, with the goal of establishing a long-term presence on the lunar surface soon after. For that to work, it’s going to need a way to provide astronauts with a steady supply of everything they need to survive and thrive, from food and water to oxygen and electricity.

Warren Buffett dumped his $850 million stake in Mary Barra’s General Motors and cut back on Amazon

Posted by in category: materials

Berkshire Hathaway said on Tuesday it has shed its holdings in General Motors and Procter & Gamble, and trimmed its stake in Amazon.com, as the conglomerate controlled by billionaire Warren Buffett boosted its cash pile to a record $157.2 billion.

In a regulatory filing detailing its U.S.-listed stock holdings as of Sept. 30, Berkshire reported no holdings in GM and P&G, after reporting stakes of $848 million and $48 million in June, and said it reduced its stake in Amazon by 5%.

Berkshire also appeared to have shed what had been a $621 million stake in Celanese, a specialty materials company.

Airbnb boss called his CEO network asking if they could hire any of the 1,900 staff he laid off

Posted by in category: futurism

As a result, he’s built a network of peers who can relate to his challenges, name-dropping Spotify CEO Daniel Ek, who had appeared on the same podcast just a few weeks before, as one of them.

“Daniel Ek doesn’t know the Brian before Airbnb,” Chesky explained. “So maybe he doesn’t know ‘the real me’…but he does know a different ‘real me’ that my childhood friends can’t know, because high school and college friends can’t possibly know what it’s like for me to go through what I’m going through.

Artificial Afterlives

Posted by in categories: habitats, media & arts, space

The afterlife Jones made.


For as long as we have had history and likely before, people have contemplated a life after this one, but might we one day create artificial afterlives? And if so, will we create heavens or hells?\

Vertex’s First Crispr Gene Editing Therapy Gets EU Backing

Posted by in categories: bioengineering, biotech/medical, genetics, health

Europe’s health regulator followed the US and UK in backing the first gene-editing therapy to use Crispr technology, a Vertex Pharmaceuticals Inc. and Crispr Therapeutics AG treatment for sickle cell disease.

The European Medicines Agency’s expert panel recommended on Friday authorizing the Vertex and Crispr drug, Casgevy, for people with severe sickle cell disease and another serious hereditary blood disorder, beta-thalassemia, which is traditionally treated with repeated transfusions. Vertex said before the ruling that it had yet to establish a European list price for the one-time therapy, which costs $2.2 million in the US.

The treatment makes precisely targeted changes in patients’ DNA, a months-long process that requires removing bone marrow and a stem cell transplant. In Europe, Vertex said its initial focus will be on countries with the highest numbers of patients, including France, Italy, the UK and Germany.
