Our Vision Weekends are the annual festivals of Foresight Institute. Held in two countries, over two weekends, you are invited to burst your tech silos and plan for flourishing long-term futures. This playlist captures the magic of our Puerto Rico edition, held February 21–23, 2025, in the heart of Old San Juan. Come for the ideas: join the conference, unconference, mentorship hours, curated 1-1s, tech demos, biohacking sessions, prize awards, and much more. Stay for fun with new friends: join the satellite gatherings, solarpunk future salsa night, beach picnic, and surprise island adventures. This year’s main conference track is dedicated to “Paths to Progress”; meaning you will hear 20+ invited presentations from Foresight’s core community highlighting paths to progress in the following areas: Existential Hope Futures, Longevity, Rejuvenation, Cryonics, Neurotech, BCIs & WBEs, Cryptography, Security & AI, Fusion, Energy, Space, and Funding, Innovation, Progress.

Purdue University researchers have developed a new type of two-dimensional (2D) nanomaterial called a tungsten carbide MXene. This small but mighty material could be used to produce hydrogen fuel for electric vehicles, possibly becoming the key to a more reliable future.

A chemical injected before MRI scans to help create sharper images may cause some patients to experience a potentially deadly complication in rare cases, a new study suggests.

Researchers from the University of New Mexico found that gadolinium – a toxic rare earth metal used in MRI scans – could mix with oxalic acid found in many foods to precipitate tiny nanoparticles of the metal in human tissues.

The research, published in the journal Magnetic Resonance Imaging, assessed the formation of these nanoparticles associated with potentially deadly health problems in the kidneys and other organs.

Since most cells naturally repel DNA, delivering these nanodevices into cells requires specialized techniques, such as transfection methods and transformation protocols. Once inside, cellular factors such as salt concentration, molecular crowding, and heterogeneous environments influence strand displacement reactions. To overcome the limitations of direct delivery, researchers are also developing transcribable RNA nanodevices encoded into plasmids or chromosomes, allowing cells to express these circuits.

Toward Smart DNA Machines and Biocomputers

DNA strand displacement has been applied to the innovation of computational models. By integrating computational principles with DNA strand displacement, the structured algorithms of traditional computing can be combined with random biochemical processes and chemical reactions in biological systems, enabling biocompatible models of computation. In the future, DNA strand displacement may enable autonomously acting DNA nanomachines to precisely manipulate biological processes, leading to quantum leaps in healthcare and life science research.

Here we report on low temperature transport measurements of encapsulated bilayer graphene nano constrictions fabricated employing electrode-free AFM-based local anodic oxidation (LAO) nanolithography. This technique allows for the creation of constrictions as narrow as 20 nm. While larger constrictions exhibit an enhanced energy gap, single quantum dot (QD) formation is observed within smaller constrictions with addition energies exceeding 100 meV, which surpass previous experiments on patterned QDs. These results suggest that transport through these narrow constrictions is governed by edge disorder combined with quantum confinement effects. Our findings introduce electrode-free AFM-LAO lithography as an easy and flexible method for creating nanostructures with tunable electronic properties without relying on patterning techniques such as e-beam lithography. The excellent control and reproducibility provided by this technique opens exciting opportunities for carbon-based quantum electronics and spintronics.
