Consciousness, “What It’s Like To Be…,” and “subjective experiences” can be explained by the Experience Recorder and Reproducer (ERR).\
We propose that a minimal primitive mind would need only to \.
My first Great Problems lecture will be on the Mind-Body problem and David Chalmers “hard problem.” See consciousness, panpsychism pages on I-phi website.
Nearly 2 million Americans suffer from type 1 diabetes — a condition that causes drastic spikes or drops in sugar levels and, in turn, dizziness, nausea, and fatigue. It’s a condition that must constantly be monitored, something that a lot of diabetics find mentally exhausting.
One diabetic, Naomi, told the BBC that she couldn’t handle “the physical or mental challenges of diabetes anymore,” and struggled to monitor her blood sugar levels multiple times a day. Naomi’s struggle isn’t unique — it’s called diabetes burnout.
There’s no cure for type 1 diabetes. However, researchers at the University of Arizona have adapted a cancer immunotherapy technique that has produced promising results in treating diabetes (in mice). The researchers engineered immune cells to fight off rogue T cells (immune cells that go haywire and attack the body) that can damage the pancreas, causing type 1 diabetes.

Neutron stars are one of the most extreme and violent things in the universe. Giant atomic nuclei, only a few kilometers in diameter but as massive as stars. And they owe their existence to the death of something majestic.
Georgia Tech engineers are working to make fertilizer more sustainable—from production to productive reuse of the runoff after application—and a pair of new studies is offering promising avenues at both ends of the process.
In one paper, researchers have unraveled how nitrogen, water, carbon, and light can interact with a catalyst to produce ammonia at ambient temperature and pressure, a much less energy-intensive approach than current practice. The second paper describes a stable catalyst able to convert waste fertilizer back into nonpolluting nitrogen that could one day be used to make new fertilizer.
Significant work remains on both processes, but the senior author on the papers, Marta Hatzell, said they’re a step toward a more sustainable cycle that still meets the needs of a growing worldwide population.
Out of Spec Reviews is known for in-depth videos of electric vehicles. The YouTube channel just posted its first review of a Tesla Cybertruck.
The Centaur upper stage has a rich legacy of launches and will add a lunar lander to the list, with the first Vulcan launch.
The first launch of the Vulcan Centaur has been delayed by five years. Missions ahead include a lunar lander and a constellation of Kuiper satellites.
Finally, he used an oscillating fan to make the droid’s domed head turn back and forth. Meanwhile, a Bluetooth speaker was inserted in the droid’s body to play droid sounds as the robot moves.
Since he could not faithfully recreate R2-D2, he called his invention R9-D9. That does not change the fact that all it takes is one look at it to know it’s Star Wars-inspired.
The project did not come without drawbacks. Hunter’s vacuum can no longer clean under sofas or beds but it’s a small price to pay to watch a Star Wars droid clean your house.
Ever think you’d see a single atom without staring down the barrel of a powerful microscope? Oxford University physicist David Nadlinger has won the top prize in the fifth annual Engineering and Physical Sciences Research Council’s (EPSRC) national science photography competition for his image ‘Single Atom in an Ion Trap’, which does something incredible: makes a single atom visible to the human eye.

Captured on an ordinary digital camera, the image shows an atom of strontium suspended by electric fields emanating from the metal electrodes of an ion trap—those electrodes are about 2mm apart. Nadlinger shot the photo through the window of the ultra-high vacuum chamber that houses the ion trap, which is used to explore the potential of laser-cooled atomic ions in new applications such as highly accurate atomic clocks and sensors, and quantum computing.
Several techniques currently are used to determine the pace of aging in animals and, to a lesser degree, in humans. However, the techniques used in humans lack accuracy, don’t assess aging in specific organs, are not widely available, and are expensive.
A multi-institutional research team measured the levels of nearly 5,000 human proteins in 5,676 people of all ages who were followed for as long as 15 years in five prospective longitudinal cohorts. Each measured protein was associated with specific organs, based on previous studies: adipose tissue, artery, brain, heart, immune tissue, intestine, kidney, liver, lung, muscle, or pancreas. Combinations of proteins indicated the pace of aging in each organ. Accelerated aging of one organ was found in nearly 20% of people, and accelerated aging of multiple organs was noted in ≈2%. Accelerated aging in a specific organ correlated with risk for developing disease in that organ. For example, people with accelerated heart aging (vs. those without it) had 250% higher risk for developing heart failure, and people with accelerated brain and vascular aging had nearly 60% higher risk for developing Alzheimer disease.
Various tools — from sequencing a person’s genome to measuring gene expression (e.g., the “methylome”) — are becoming available to predict a person’s risk for developing particular diseases. Will these predictions lead to interventions that lower risk? The jury is still out on that question.
