MEXICO CITY (AP) — Ecologists from Mexico’s National Autonomous university on Friday relaunched a fundraising campaign to bolster conservation efforts for axolotls, an iconic, endangered fish-like type of salamander.

The campaign, called “Adoptaxolotl,” asks people for as little as 600 pesos (about $35) to virtually adopt one of the tiny “water monsters.” Virtual adoption comes with live updates on your axolotl’s health. For less, donors can buy one of the creatures a virtual dinner.

In their main habitat the population density of Mexican axolotls (ah-ho-LOH’-tulz) has plummeted 99.5% in under two decades, according to scientists behind the fundraiser.

One of ray kurzweils wonder machines are already here self assembled nanobots called foglet machines. This could allow for future avatars that people could pilot for daily life.

Colloidal magnetic nanoparticles are candidates for application in biology, medicine and nanomanufac-turing. Understanding how these particles interact collectively in fluids, especially how they assemble and aggregate under external magnetic fields, is critical for high quality, safe, and reliable deployment of these particles. Here, by applying magnetic forces that vary strongly over the same length scale as the colloidal stabilizing force and then varying this colloidal repulsion, we can trigger self-assembly of these nanoparticles into parallel line patterns on the surface of a disk drive medium. Localized within nanometers of the medium surface, this effect is strongly dependent on the ionic properties of the colloidal fluid but at a level too small to cause bulk colloidal aggregation.

5th BigBrain Workshop 2021
22 September 2021 — Applications.
Chair: Kathleen Rockland.

The Unique Cytoarchitecture and Wiring of The Default Mode Network.
Casey Paquola.

Background. Complex behaviours benefit from parallel distributed processing in multiple brain networks. The roles of certain networks are well-defined, while others remain elusive. Arguably, none are so elusive as the default mode network (DMN); a distributed set of brain regions that decrease in activity during many externally oriented tasks. Revealing the cytoarchitectural composition and connectional layout of the DMN is crucial to defining its role in complex behaviours.

Method. We examined the cytoarchitectural composition of the DMN using an established cortical type atlas (García-Cabezas et al., 2020; Von Economo and Koskinas, 1925) and by applying non-linear dimensionality reduction to BigBrain-derived staining intensity profiles (Paquola et al., 2019). Next, we used magnetic resonance imaging (MRI) to explicate structural wiring and effective connectivity of the whole brain. In both modalities, we examined the influence of cytoarchitecture on extrinsic connectivity of the DMN. Finally, we evaluated the uniqueness of the DMN relative to other large-scale functional brain networks.

Basically on the pro side it could be something good to help earth but really if is on the bad side we probably want to cloak the earth with an invisibility cloak and force fields ideally so they don’t wipe us out.

An experiment aboard NASA’s Psyche mission achieved “first light” by sending and receiving its first deep-space laser communications from far beyond the moon.

An amazing graph theoretic analysis of the C. elegans neuropeptide connectome!

Neuromodulation by peptides is essential for brain function. By comprehensively mapping neuropeptide signaling in the nematode C. elegans, Ripoll-Sánchez et al. define a dense wireless network whose organization differs in important ways from wired brain circuits. This network is a prototype for understanding neuropeptide signaling networks in larger brains.

Just weeks before the management shakeup at OpenAI rocked Silicon Valley and made international news, the company’s cofounder and chief scientist Ilya Sutskever explored the transformative potential of artificial general intelligence (AGI), highlighting how it could surpass human intelligence and profoundly transform every aspect of life. Hear his take on the promises and perils of AGI — and his optimistic case for how unprecedented collaboration will ensure its safe and beneficial development. (Recorded October 17, 2023)
