Humankind on the verge of evolutionary traps, a new study: …For the first time, scientists have used the concept of evolutionary traps on human societies at large.

For the first time, scientists have used the concept of evolutionary traps on human societies at large. They find that humankind risks getting stuck in 14 evolutionary dead ends, ranging from global climate tipping points to misaligned artificial intelligence, chemical pollution, and accelerating infectious diseases.

The evolution of humankind has been an extraordinary success story. But the Anthropocene—the proposed geological epoch shaped by us humans—is showing more and more cracks. Multiple global crises, such as the COVID-19 pandemic, climate change, food insecurity, financial crises, and conflicts have started to occur simultaneously in something which scientists refer to as a polycrisis.

Russia and China have both recently developed intercontinental ballistic missiles capable of dropping several nuclear bombs at once.

Google Maps is getting a few new updates, including a social feature that is designed to help people plan and collaborate with their friends. The navigation platform is also adding improved transit directions and emoji reactions.

The new social feature is designed to take planning out of your group chat and into Google Maps. The platform is updating its list feature to make it easier for people to share places, plan with friends and vote on group activities. With this new feature, you’ll be able to create a collaborative list to to start planning a hangout after you share a place in Maps with friends. Everyone in the group can add places they’re interested in visiting, and vote with an emoji, like a heart or a thumbs down.

The new research, part of the NIH BRAIN Initiative, paves the way toward treating, preventing, and curing brain disorders.

Salk Institute researchers, as part of a larger collaboration with research teams around the world, analyzed more than half a million brain cells from three human brains to assemble an atlas of hundreds of cell types that make up a human brain in unprecedented detail.

The research, published in a special issue of the journal Science on October 13, 2023, is the first time that techniques to identify brain cell subtypes originally developed and applied in mice have been applied to human brains.

Data from the Surface Water and Ocean Topography (SWOT) satellite was used to map surface heights of the planet’s oceans and freshwater lakes and rivers.

An excellent short review on structure and function of the hypothalamus, one of my favorite regions of the brain! Link: https://www.science.org/doi/10.1126/science.adh8488 #neuroscience #biology

The hypothalamus (“hypo” meaning below, and “thalamus” meaning bed) consists of regulatory circuits that support basic life functions that ensure survival. Sitting at the interface between peripheral, environmental, and neural inputs, the hypothalamus integrates these sensory inputs to influence a range of physiologies and behaviors. Unlike the neocortex, in which a stereotyped cytoarchitecture mediates complex functions across a comparatively small number of neuronal fates, the hypothalamus comprises upwards of thousands of distinct cell types that form redundant yet functionally discrete circuits. With single-cell RNA sequencing studies revealing further cellular heterogeneity and modern photonic tools enabling high-resolution dissection of complex circuitry, a new era of hypothalamic mapping has begun. Here, we provide a general overview of mammalian hypothalamic organization, development, and connectivity to help welcome newcomers into this exciting field.

The Matic is a fully autonomous robot vacuum that its founders claim will clean your floors without getting stuck on cables or toys and without sending a map of your home to the cloud. And it’ll only cost you $1,800.

The Matic is a new robot vacuum with a different approach to cleaning your floors. Built by two former Google Nest engineers, it’s designed to move around your home in the same way most humans would, processing things visually instead of spatially. It uses five RGB cameras to navigate, rather than the sensors, bumpers, and lidar tech found on most of today’s robot vacs. In theory, this makes it less prone to common robot vacuum pitfalls —such as high-pile rugs, cables, and tight spaces — because it can actually see where it’s going in real time rather than relying on a preprogrammed map. It also operates locally — with no cloud component at all. Mapping is done on the device, and it doesn’t require an internet connection to run, so your data should never leave your home. $1,800 robot vacuum thinks it can beat the best of them.

Google continues to integrate more AI into its suite of apps.

The new telescope would allow scientists to “understand the beginning, history, and makeup of the universe.”

In a quest to advance the knowledge concerning the beginning of the universe, known as the Cosmic Microwave Background, the National Science Foundation is set to grant up to $21.4 million to the University of Chicago. The agreement will see $3.7 million awarded to the team next year, in a project aimed at developing final designs for a next-generation set of telescopes that will map the light from the earliest moments of the universe.

The project, named CMB-S4, will be led by researchers at UOC and Lawrence Berkeley National Laboratory and aims to construct infrastructure and telescopes… More.
