Last week, a team of researchers from the University of California, Berkeley published a highly anticipated paper in the journal Nature describing an “autonomous laboratory” or “A-Lab” that aimed to use artificial intelligence (AI) and robotics to accelerate the discovery and synthesis of new materials.

Dubbed a “self-driving lab,” the A-Lab presented an ambitious vision of what an AI-powered system could achieve in scientific research when equipped with the latest techniques in computational modeling, machine learning (ML), automation and natural language processing.

After 151 years, Popular Science will no longer offer a magazine

Posted by in category: science

Popular Science magazine shifted to an all-digital format a couple of years ago, and now even that’s gone.

After 151 years, Popular Science will no longer be available to purchase as a magazine.


The long-running publication has come to an end.

How Memory Makes Us and Breaks Truth: The Rashomon Effect and the Science of How Memories Form and Falter in the Brain

Posted by in categories: neuroscience, science

It is already disorienting enough to accept that our attention only absorbs a fraction of the events and phenomena unfolding within and around us at any given moment. Now consider that our memory only retains a fraction of what we have attended to in moments past. In the act of recollection, we take these fragments of fragments and try to reconstruct from them a totality of a remembered reality, playing out in the theater of the mind — a stage on which, as neuroscientist Antonio Damasio has observed in his landmark work on consciousness, we often “use our minds not to discover facts, but to hide them.”

We do this on the personal level — out of such selective memory and by such exquisite exclusion, we compose the narrative that is the psychological pillar of our identity. We do it on the cultural level — what we call history is a collective selective memory that excludes far more of the past’s realities than it includes. Borges captured this with his characteristic poetic-philosophical precision when he observed that “we are our memory… that chimerical museum of shifting shapes, that pile of broken mirrors.” To be aware of memory’s chimera is to recognize the slippery, shape-shifting nature of even those truths we think we are grasping most firmly.

Weaponizing Brain Science: Neuroweapons — Part 2 of 2

The second installment of this two-part podcast continues the conversation with Dr. Giordano on the implications of weaponizing brain science. In an article he wrote for HDIAC in 2016 titled ‘Battlescape Brain’, Dr. Giordano hinted at the possibility of a neuroweapons arms race that could follow from international surveillance. Dr. Giordano provides an updated look at these concerns in the context of today’s environment. He concludes by describing ethical frameworks that could regulate future policies for biotechnology as the world moves forward in this dynamic area.

HDIAC Podcast — Weaponizing Brain Science: Neuroweapons — Part 1 of 2

Posted by in categories: chemistry, neuroscience, science, security

https://www.hdiac.org/podcast/neuroweapons-part-1/

In part one of this two-part podcast, HDIAC analyst Mara Kiernan interviews Dr. James Giordano, a Professor in the department of Neurology and Biochemistry at Georgetown University Medical Center. The discussion begins with Dr. Giordano defining neuroweapons and explaining their applied technologies. He provides insight into the manner in which international weapons conventions govern the use neuroweapons and discusses the threats presented by neuroweapons in today’s environment. Dr. Giordano goes on to review the need for continuous monitoring, including his views regarding challenges and potential solutions for effectively understanding global developments in neuroweapon technologies.

Scientists Warn That AI Threatens Science Itself

Posted by in categories: internet, robotics/AI, science

What role should text-generating large language models (LLMs) have in the scientific research process? According to a team of Oxford scientists, the answer — at least for now — is: pretty much none.

In a new essay, researchers from the Oxford Internet Institute argue that scientists should abstain from using LLM-powered tools like chatbots to assist in scientific research on the grounds that AI’s penchant for hallucinating and fabricating facts, combined with the human tendency to anthropomorphize the human-mimicking word engines, could lead to larger information breakdowns — a fate that could ultimately threaten the fabric of science itself.

“Our tendency to anthropomorphize machines and trust models as human-like truth-tellers, consuming and spreading the bad information that they produce in the process,” the researchers write in the essay, which was published this week in the journal Nature Human Behavior, “is uniquely worrying for the future of science.”
