Age of the Androids
Posted in policy, robotics/AI
While some might view the emergence of humanoids with apprehension, a future filled with robots is likely to be a positive development for most. But as with anything, policy and society must be ready if, and when, they arrive.
There is growing corporate interest in humanoid robots to replace human labor. Tesla’s recently unveiled Bumble C robot may mark a turning point in an industry that has thus far focused on specialized machines produced in limited quantities. Should Tesla succeed, what does a mass-produced humanoid robot mean for the future of humanity?

Revolutionary improvements to automation and production may one day create machines able to produce almost anything, quickly and cheaply, and far faster and more varied than modern 3D Printers. Such devices are sometimes known as Santa Claus Machines, Cornucopia Devices, or Clanking Del-Replicators, and today we will examine how likely such technology is, how far off in the future they might be, and what impact they would have on society.

It’s time we talked about loop quantum gravity. What exactly is it? What are the loops? And can it really defeat string theory in our quest for a Theory of Everything?
High-Risk, High-Payoff Bio-Research For National Security Challenges — Dr. David A. Markowitz, Ph.D., IARPA
Dr. David A. Markowitz, Ph.D. (https://www.markowitz.bio/) is a Program Manager at the Intelligence Advanced Research Projects Activity (IARPA — https://www.iarpa.gov/) which is an organization that invests in high-risk, high-payoff research programs to tackle some of the most difficult challenges of the agencies and disciplines in the U.S. Intelligence Community (IC).
IARPA’s mission is to push the boundaries of science to develop solutions that empower the U.S. IC to do its work better and more efficiently for national security. IARPA does not have an operational mission and does not deploy technologies directly to the field, but instead, they facilitate the transition of research results to IC customers for operational application.
Infectious diseases expert George Thompson has been studying and treating fungal diseases for over two decades. He monitors their spread, symptoms and relative risks. Lately, he has been more concerned about a rising threat: the spread of disease-causing fungi outside of their traditional hot spots.
In a commentary published in Annals of Internal Medicine, Thompson and his co-author from the Mycotic Diseases Branch at the Centers for Disease Control and Prevention Tom Chiller raised the alarm. They noted the expanding presence and emerging risks from three endemic fungal diseases: histoplasmosis, blastomycosis and coccidioidomycosis (Valley fever).
“These three fungal diseases usually inhabit specific U.S. regions conducive to their survival,” said Thompson. He is a professor at the UC Davis School of Medicine in the Department of Internal Medicine, Division of Infectious Diseases, and the Department of Medical Microbiology and Immunology. “Recently, we are finding more cases of these diseases outside their known areas, taking clinicians and patients by surprise.”

The challenge of fabricating nanowires directly on silicon substrates for the creation of the next generation of electronics has finally been solved by researchers from Tokyo Tech. Next-generation spintronics will lead to better memory storage mechanisms in computers, making them faster and more efficient.
As our world modernizes faster than ever before, there is an ever-growing need for better and faster electronics and computers. Spintronics is a new system which uses the spin of an electron, in addition to the charge state, to encode data, making the entire system faster and more efficient. Ferromagnetic nanowires with high coercivity (resistance to changes in magnetization) are required to realize the potential of spintronics. Especially L 10-ordered (a type of crystal structure) cobalt-platinum (CoPt) nanowires.
Conventional fabrication processes for L 10-ordered nanowires involve heat treatment to improve the physical and chemical properties of the material, a process called annealing on the crystal substrate; the transfer of a pattern onto the substrate through lithography; and finally the chemical removal of layers through a process called etching. Eliminating the etching process by directly fabricating nanowires onto the silicon substrate would lead to a marked improvement in the fabrication of spintronic devices. However, when directly fabricated nanowires are subjected to annealing, they tend to transform into droplets as a result of the internal stresses in the wire.
Medical television shows sometimes depict thoughts skipping across the brain as action potentials that ignite like exploding stars. While it looks dramatic and impressive, today’s brain-imaging technologies can’t visualize brain activity so sensitively. A new magnetic resonance imaging (MRI) technique called DIANA – direct imaging of neuronal activity – may get us closer, though.
An alternative to BOLD fMRI
A brain signal begins with an action potential caused by rapid changes in voltage across cellular membranes. Researchers involved in this proof-of-concept study, reported in Science, say that DIANA might measure this neuronal activity by capturing the intracellular voltage of a group of neurons.
The crypto community is petitioning U.S. Congress to investigate possible connections between SEC Chair Gary Gensler and FTX.
