Primordial Fuel: Uncovering Hydrogen’s Role at the Origin of Life

Posted by in categories: biological, chemistry, habitats, sustainability

A recent study reveals how hydrogen gas, often touted as the energy source of tomorrow, provided energy in the past, at the origin of life 4 billion years ago. Hydrogen gas is clean fuel. It burns with oxygen in the air to provide energy with no CO2.

Hydrogen is a key to sustainable energy for the future. Though humans are just now coming to realize the benefits of hydrogen gas (H2 in chemical shorthand), microbes have known that H2 is a good fuel for as long as there has been life on Earth. Hydrogen is ancient energy.

The very first cells on Earth lived from H2 produced in hydrothermal vents, using the reaction of H2 with CO2 to make the molecules of life. Microbes that thrive from the reaction of H2 and CO2 can live in total darkness, inhabiting spooky, primordial habitats like deep-sea hydrothermal vents or hot rock formations deep within the Earth’s crust, environments where many scientists think that life itself arose.

Scientists Discover That “Transcendent” Thinking May Grow Teens’ Brains

Posted by in categories: education, neuroscience

Scientists at CANDLE have discovered that adolescents who grapple with the bigger meaning of social situations experience greater brain growth, which predicts stronger identity development and life satisfaction years later.

Scientists at the USC Rossier School of Education’s Center for Affective Neuroscience, Development, Learning and Education (CANDLE), have shown for the first time that a type of thinking, that has been described for over a century as a developmental milestone of adolescence, may grow teenagers’ brains over time.

This kind of thinking, which the study’s authors call “transcendent,” moves beyond reacting to the concrete specifics of social situations to also consider the broader ethical, systems-level, and personal implications at play. Engaging in this type of thinking involves analyzing situations for their deeper meaning, historical contexts, civic significance, and/or underlying ideas.

Unlocking Quantum Secrets With Spin-Squeezing Atomic Entanglement

Posted by in categories: particle physics, quantum physics

Researchers have developed methods to entangle large numbers of particles, improving the precision and speed of quantum measurements. These advancements could revolutionize quantum sensors and atomic clocks, with potential applications in fundamental physics research.

Opening new possibilities for quantum sensors, atomic clocks, and tests of fundamental physics, JILA researchers have developed new ways of “entangling” or interlinking the properties of large numbers of particles. In the process they have devised ways to measure large groups of atoms more accurately even in disruptive, noisy environments.

The new techniques are described in a pair of papers published in Nature.[1] JILA is a joint institute of the National Institute of Standards and Technology (NIST) and the University of Colorado Boulder.

MIT’s Self-Powered Sensor Automatically Harvests Ambient Magnetic Energy

Posted by in categories: electronics, energy

A system designed at MIT could allow sensors to operate in remote settings, without batteries.

MIT researchers have developed a battery-free, self-powered sensor that can harvest energy from its environment.

Because it requires no battery that must be recharged or replaced, and because it requires no special wiring, such a sensor could be embedded in a hard-to-reach place, like inside the inner workings of a ship’s engine. There, it could automatically gather data on the machine’s power consumption and operations for long periods of time.
