Meet the presidential hopeful who wants to end death

Posted by in categories: biological, geopolitics, life extension, robotics/AI, transhumanism

A new feature story out on book Transhuman Citizen:


A former presidential candidate who believes a dramatic increase in science funding can help humans achieve biological immortality has told Newsweek he is considering a third White House run in 2028.

Zoltan Istvan ran as an independent candidate during the 2016 presidential election when he attracted widespread media attention for driving a bus modified to look like a coffin from San Francisco to Washington D.C., to illustrate his believe that death can be overcome.

NASA seeks industry support in GLIMR concept study

Posted by in categories: biological, chemistry, economics, engineering, space, sustainability

WASHINGTON — The National Aeronautics and Space Administration (NASA) has announced that the agency is seeking assistance from industry as it begins a study into its Geostationary Littoral Imaging and Monitoring Radiometer (GLIMR) Access to Space (ATS) approach.

The GLIMR mission aims to provide transformative rapid observations of dynamic coastal zone ecosystems throughout the Gulf of Mexico (GoM) and coastal continental U.S. (CONUS). Its goal is to observe and monitor ocean biology, chemistry, and ecology to help protect ecosystem sustainability, improve resource management, and enhance economic activity. This includes identifying and tracking harmful algal blooms and oil spills, while also observing, quantifying, and understanding processes associated with rapid changes in phytoplankton growth.

The GLIMR ATS scope is expected to include several key components and activities: the spacecraft itself, the launch vehicle, the integration and testing of the GLIMR payload with the spacecraft, and the integration of the spacecraft with the launch vehicle and subsequent launch. It will also cover the command uplink from the industry-provided Mission Operations Center (MOC), the downlink of GLIMR engineering and science telemetry to industry-allocated ground stations, and the delivery of error-checked GLIMR data to various mission partners. Additionally, it encompasses all related tasks and support required during the planned GLIMR Mission, such as pre-launch planning, launch support, in-orbit check-out, and operations.

New Study Reveals Molecular Secret to Lifelong Memories

Posted by in categories: biological, transportation

New research identifies the molecule KIBRA as a critical “glue” in stabilizing long-term memories by maintaining synaptic strength, offering insights into memory persistence despite ongoing cellular changes.

Whether it’s a first-time visit to a zoo or when we learned to ride a bicycle, we have memories from our childhoods kept well into adult years. But what explains how these memories last nearly an entire lifetime?

A new study in the journal Science Advances, conducted by a team of international researchers, has uncovered a biological explanation for long-term memories. It centers on the discovery of the role of a molecule, KIBRA, that serves as a “glue” to other molecules, thereby solidifying memory formation.

Divergent landscapes of A-to-I editing in postmortem and living human brain

Posted by in categories: biological, neuroscience

Adenosine-to-inosine editing is a form of RNA modification observed in the human brain transcriptome. Here the authors question the accuracy of utilizing postmortem samples to reflect the RNA biology of living brains. This is due to significant differences in adenosine-to-inosine editing between living and postmortem brain tissues, with most sites exhibiting higher editing levels postmortem.

The 5th Industrial Revolution

Posted by in categories: biological, existential risks, space travel, sustainability

In this episode of the 5th Industrial Revolution VODcast we sit down with Dr. Jordan Okie of Arizona State University School of Earth and Space Exploration to discuss a key relevancy to the next industrial revolution, sustainability, through the lens of Dr. Okie’s area of expertise: Ecology and Biology. Our key takeaways: We are in a race against time and extinction. We will need to find a way to evolve through technology to survive, be it here on Earth or in our exploration of Space.

Researchers find brains can tune their navigation system without landmarks

Posted by in categories: biological, engineering, neuroscience

Johns Hopkins research sheds new light on how mammals track their position and orientation while moving, revealing that visual motion cues alone allow the brain to adjust and recalibrate its internal map even in the absence of stable visual landmarks.

Their results are published in Nature Neuroscience.

“When you move through space, you have a lot of competing telling you where you are and how fast you are going, and your brain has to make sense of that,” said study co-leader Noah Cowan, professor of mechanical engineering at the Whiting School of Engineering and director of the Locomotion in Mechanical and Biological Systems (LIMBS) Laboratory.

How Do Our Memories Last a Lifetime? New Study Offers a Biological Explanation

Posted by in categories: biological, neuroscience

Whether it’s a first-time visit to a zoo or when we learned to ride a bicycle, we have memories from our childhoods kept well into adult years. But what explains how these memories last nearly an entire lifetime?

A new study in the journal Science Advances, conducted by a team of international researchers, has uncovered a biological explanation for long-term memories. It centers on the discovery of the role of a molecule, KIBRA, that serves as a “glue” to other molecules, thereby solidifying memory formation.

“Previous efforts to understand how molecules store long-term memory focused on the individual actions of single molecules,” explains André Fenton, a professor of neural science at New York University and one of the study’s principal investigators. “Our study shows how they work together to ensure perpetual memory storage.”

How China’s Moon mission could reveal the origins of life on Earth

Posted by in categories: biological, nuclear energy, space, sustainability

Update: China´s Moon Mission Returned Now Samples from the #Moon to #Earth. Why this is important, specially for the origin of life:


On June 1, China’s Chang’e-6 lander touched down in the South Pole-Atkin Basin — the largest, deepest, and oldest impact crater on the Moon. The probe almost immediately set to work drilling into the ground to collect about 2 kilograms of lunar material, which is already headed back to Earth, with a landing in Mongolia planned for June 25. It isn’t just planetary geologists who are excited at what the returning rocks and soil might reveal. If we’re lucky, the first samples from the lunar farside could also include some of the oldest fossils ever found.

The SPA basin, as it’s sometimes called, is the result of a gigantic impact that occurred between 4.2 and 4.3 billion years ago, at a time when the Moon and Earth were very close neighbors. The crater is roughly 2,500 kilometers (1,600 miles) in diameter and between 6.2 km and 8.2 km (3.9 to 5.1 mi) deep, encompassing several smaller craters like the Apollo basin, where Chang’e-6 landed, and Shackleton crater, parts of which lie in perpetual shadow.
