Many scientists, operating with a materialist worldview, argue that consciousness emerges out of inanimate molecules. In contrast, Roger Penrose’s longtime collaborator, Stuart Hameroff, puts forward the controversial case that consciousness precedes life and that we have evidence for this from a recent NASA experiment.

Tiny new lasers fill a long-standing gap in the rainbow of visible-light colors
Posted by Shubham Ghosh Roy in categories: biotech/medical, computing
It’s not easy making green.
For years, scientists have fabricated small, high-quality lasers that generate red and blue light. However, the method they typically employ — injecting electric current into semiconductors — hasn’t worked as well in building tiny lasers that emit light at yellow and green wavelengths. Researchers refer to the dearth of stable, miniature lasers in this region of the visible-light spectrum as the “green gap.” Filling this gap opens new opportunities in underwater communications, medical treatments and more.
Compact laser diodes can emit infrared, red and blue wavelengths, but are highly inefficient at producing green and yellow wavelengths, a region known as the ‘green gap’. (Image: S. Kelley, NIST)

Researchers create entangled quantum magnets with protected quantum excitations
Posted by Shubham Ghosh Roy in categories: particle physics, quantum physics
Quantum magnets are materials that realize a quantum superposition of magnetic states, bringing quantum phenomena from the microscopic to the macroscopic scale. These materials feature exotic quantum excitations–including fractional excitations where electrons behave as if they were split into many parts–that do not exist anywhere outside of this material.
To manipulate how the atoms behaved inside the quantum material the researchers had assembled, they poked each individual atom with a tiny needle. This technique allows for the accurate probing of qubits at the atomic level. The needle, in reality an atomically sharp metal tip, served to excite the atoms’ local magnetic moment, which resulted in topological excitations with enhanced coherence.
“Topological quantum excitations, such as those realized in the topological quantum magnet we now built, can feature substantial protection against decoherence. Ultimately, the protection offered by these exotic excitations can help us overcome some of the most pressing challenges of currently available qubits,” Lado says.

Using atomic excitations to measure the rotation of spacetime
Posted by Saúl Morales Rodriguéz in categories: cosmology, particle physics
How would atoms behave near a supermassive object? We know how atoms behave in extremely weak gravity like that at the Earth’s surface: They can be excited from a lower energy level to a higher one when an electron absorbs a photon or a nucleus absorbs a gamma ray, and so on. But what if the atom is in a strong gravitational field such as one near a supermassive, rotating black hole or rotating neutron star?

Scientists unlock the secrets of how a key protein converts DNA into RNA
Posted by Saúl Morales Rodriguéz in category: biotech/medical
Researchers at the Department of Energy’s SLAC National Accelerator Laboratory have uncovered new insights into the fundamental mechanisms of RNA polymerase II (Pol II), the protein responsible for transcribing DNA into RNA. Their study shows how the protein adds nucleotides to the growing RNA chain. The results, published in Proceedings of the National Academy of Sciences, have potential applications in drug development.
