Physicist Pan Jianwei outlines timetable for quantum-based ultra-secure networks that will have coverage across the world.

The pace of engineering and science is speeding up, rapidly leading us toward a “Technological Singularity” — a point in time when superintelligent machines achieve and improve so much so fast, traditional humans can no longer operate at the forefront. However, if all goes well, human beings may still flourish greatly in their own ways in this unprecedented era.

If humanity is going to not only survive but prosper as the Singularity unfolds, we will need to understand that the Technological Singularity is an Experiential Singularity as well, and rapidly evolve not only our technology but our level of compassion, ethics and consciousness.

The aim of The Consciousness Explosion is to help curious and open-minded readers wrap their brains around these dramatic emerging changes– and empower readers with tools to cope and thrive as they unfold.

It’s not a tool, but an alien agent, says Yuval Noah Harari in an interview.

Summary: A recent study reveals that specific brain cells respond not only to smells but also to images and written words related to those scents, providing deeper insight into human odor perception. Researchers found that neurons in the olfactory cortex and other brain regions, like the hippocampus and amygdala, distinguish between different smells and associate them with visual cues.

This research, using data from epilepsy patients, bridges a gap between animal and human studies on olfactory processing. Remarkably, individual neurons responded to scent, image, and word, suggesting that smell processing integrates visual and semantic information early on. These findings could lead to future innovations in “olfactory aids.” The study emphasizes the interconnected nature of smell and visual memory in the human brain.

Summary: Researchers have developed an AI-powered “electronic tongue” capable of distinguishing subtle differences in liquids, such as milk freshness, soda types, and coffee blends. By analyzing sensor data through a neural network, the device achieved over 95% accuracy in identifying liquid quality, authenticity, and potential safety issues. Interestingly, when the AI was allowed to select its own analysis parameters, it outperformed human-defined settings, showing how it holistically assessed subtle data.

This technology, which uses graphene-based sensors, could revolutionize food safety assessments and potentially extend to medical diagnostics. The device’s AI insights also provide a unique view into the neural network’s decision-making process. This innovation promises practical applications across industries where quality and safety are paramount.

It’s not your ordinary pocket watch: The researchers showed that, at least under a narrow range of conditions, their clock could beat a benchmark for precision called the “standard quantum limit”—what physicist Adam Kaufman refers to as the “Holy Grail” for optical atomic clocks.

“What we’re able to do is divide the same length of time into smaller and smaller units,” said Kaufman, senior author of the new study and a fellow at JILA, a joint research institute between CU Boulder and NIST. “That acceleration could allow us to track time more precisely.”

The team’s advancements could lead to new quantum technologies. They include sensors that can measure subtle changes in the environment, such as how Earth’s gravity shifts with elevation.

Two researchers whose work has led to the AI revolution won the 2024 Nobel Prize in physics. A materials physicist explains statistical mechanics, the physics field behind their discoveries.

“The isotope values of these carbonates point toward extreme amounts of evaporation, suggesting that these carbonates likely formed in a climate that could only support transient liquid water,” said Dr. David Burtt.

Was the planet Mars ever habitable and what conditions led to it becoming the uninhabitable world we see today? This is what a recent study published in the Proceedings of the National Academy of Sciences hopes to address as a team of researchers from the United States and Canada investigated how carbonate minerals found within Gale Crater on Mars could help paint a clearer picture of past conditions on the Red Planet and whether it was habitable. This study holds the potential to help scientists better understand the formation and evolution of Mars and whether it once had the necessary conditions to support life as we know it.

Studying carbonate minerals is important due to their ability to tell scientists how a climate formed and evolved over time, with these carbonate minerals containing large amounts of carbon and oxygen isotopes, specifically Carbon-13 and Oxygen-18, which the study notes is the highest amount of these isotopes identified on the Red Planet. Carbon-13 and Oxygen-18 are known as environmental isotopes, which are used to better understand the interactions between a planet’s ocean and atmosphere and how life could exist. While Earth is the only known planet to support life, studying these isotopes on Mars could help scientists better understand if life could have formed on Mars long ago.
