After a decade, CRISPR gene editing is a ‘revolution in progress.’ What does the future hold?

Posted by in categories: bioengineering, biotech/medical, food

But every once in a while, an idea is so powerful and so profound its effects are felt much faster.

That’s been the case with CRISPR gene editing, which celebrates a 10th anniversary this month. It has already had a substantial impact on laboratory science, improving precision and speeding research, and it has led to clinical trials for a handful of rare diseases and cancers.

Over the next decade, scientists predict, CRISPR will yield multiple approved medical treatments and be used to modify crops, making them more productive and resistant to disease and climate change.

The Believing Brain: Evolution, Neuroscience, and the Spiritual Instinct

Posted by in categories: evolution, neuroscience

God, they say, is in the details. But could God also be in our frontal lobes? Every culture from the dawn of humankind has imagined planes of existence beyond the reach of our senses, spiritual domains that shape our Earthly experiences. Why do beliefs of the fantastic hold such powerful sway over our species? Is there something in our evolutionary history that points to an answer? Does neuroscience hold the key? Straddling the gap between science and religion, Brian Greene is joined by renowned neuroscientists, anthropologists, and evolutionary biologists, to explore one of the most profound mysteries of our existence.

PARTICIPANTS: Lisa Barrett, Barbara J. King, Zoran Josipovic, Steven Pinker.

45:33 AlphaFold.
48:39 Gato, A generalist agent.
50:02 Solving *everything else*

This premium episode is a documentary-style video about the history and importance of Alphabet subsidiary, DeepMind. Demis Hassabis, founder, was a chess prodigy by the time he was 13 years old. He went on to conclude he wanted to “solve intelligence” by building artificial intelligence agents and using digital tools. The team at DeepMind has created systems that defeated the world’s best chess and Go professionals. They’ve also cracked the code on the infamous ‘protein-folding problem.’ Demis Hassabis and DeepMind are fascinating. Moreover, they’re still just getting started.

Astronomers Say They Have Spotted the Universe’s First Stars

Posted by in category: alien life

A group of astronomers poring over data from the James Webb Space Telescope (JWST) has glimpsed light from ionized helium in a distant galaxy, which could indicate the presence of the universe’s very first generation of stars.

These long-sought, inaptly named “Population III” stars would have been ginormous balls of hydrogen and helium sculpted from the universe’s primordial gas. Theorists started imagining these first fireballs in the 1970s, hypothesizing that, after short lifetimes, they exploded as supernovas, forging heavier elements and spewing them into the cosmos. That star stuff later gave rise to Population II stars more abundant in heavy elements, then even richer Population I stars like our sun, as well as planets, asteroids, comets and eventually life itself.

A quantum video reel: Time-of-flight quantum tomography of an atom in an optical tweezer

Posted by in categories: particle physics, quantum physics

When it comes to creating ever more intriguing quantum systems, a constant need is finding new ways to observe them in a wide range of physical scenarios. JILA Fellow Cindy Regal and JILA and NIST Fellow Ana Maria Rey have teamed up with Oriol Romero-Isart from the University of Innsbruck and IQOQI to show that a trapped particle in the form of an atom readily reveals its full quantum state with quite simple ingredients, opening up opportunities for studies of the quantum state of ever larger particles.

In the an atom does not behave as a point particle; instead it behaves more as a wave. Its properties (e.g., its position and velocity) are described in terms of what is referred to as the wavefunction of the atom. One way to learn about the wavefunction of a particle is to let the atom fly and then capture its location with a camera.

And with the right tricks, pictures can be taken of the particle’s quantum state from many vantage points, resulting in what is known as quantum tomography (“tomo” being Greek for slice or section, and “graphy” meaning describing or recording). In the work published in Nature Physics, the authors used a rubidium atom placed carefully in a specific state of its motion in a tightly focused laser beam, known as an optical tweezer. And they were able to observe it from many vantage points by letting it evolve in the optical tweezer in time. Like a ball rolling in a bowl, at different times the velocity and location of the particle interchange, and by snapping pictures at the right time during a video reel of the ball, many vantages of the particle’s state can be revealed.

Microsoft Defender can now isolate compromised Linux endpoints

Posted by in category: computing

Microsoft announced today that it added device isolation support to Microsoft Defender for Endpoint (MDE) on onboarded Linux devices.

Enterprise admins can manually isolate Linux machines enrolled as part of a public preview using the Microsoft 365 Defender portal or via API requests.

Once isolated, threat actors will no longer have a connection to the breached system, cutting off their control and blocking malicious activity like data theft.
