Octo-eyes: Unraveling Octopus Vision with Neural Mapping

Posted by in categories: evolution, mapping, neuroscience

Summary: Researchers mapped neural activity in an octopus’s visual system, revealing striking similarities to humans.

The team observed neural responses to light and dark spots, thereby creating a map resembling the organization of the human brain. Interestingly, octopuses and humans last shared a common ancestor around 500 million years ago, suggesting independent evolution of such complex visual systems.

These findings contribute greatly to our understanding of cephalopod vision and brain structure.

Decades-long bet on consciousness ends — and it’s philosopher 1, neuroscientist

Posted by in category: neuroscience

Christof Koch wagered David Chalmers 25 years ago that researchers would learn how the brain achieves consciousness by now. But the quest continues.

Perovskite solar cells set new world record for power conversion efficiency

Posted by in categories: solar power, sustainability

Perovskite solar cells designed by a team of scientists from the National University of Singapore (NUS) have attained a world record efficiency of 24.35% with an active area of 1 cm2. This achievement paves the way for cheaper, more efficient and durable solar cells.

To facilitate consistent comparisons and benchmarking of different solar cell technologies, the photovoltaic (PV) community uses a standard size of at least 1 cm2 to report the efficiency of one-sun in the “Solar cell efficiency tables.” Prior to the record-breaking feat by the NUS team, the best 1 cm2 recorded a of 23.7%. This ground-breaking achievement in maximizing from next-generation will be crucial to securing the world’s energy future.

Perovskites are a class of materials that exhibit high light absorption efficiency and ease of fabrication, making them promising for solar cell applications. In the past decade, perovskite solar cell technology has achieved several breakthroughs, and the technology continues to evolve.

Evidence of the amino acid tryptophan found in space

Posted by in categories: materials, space

Using data from the Spitzer space observatory, Dr. Susana Iglesias-Groth, a researcher from The Instituto de Astrofísica de Canarias (IAC), has found evidence for the existence of the amino acid tryptophan in the interstellar material in a nearby star-forming region. The research is published in Monthly Notices of the Royal Astronomical Society.

High amounts of tryptophan were detected in the Perseus molecular complex, specifically in the IC348 star system, a star-forming region that lies 1,000 away from Earth—relatively close in astronomical terms. The region is generally invisible to the , but shines brightly when viewed in .

Tryptophan is one of the 20 amino acids essential for the formation of key proteins for life on Earth, and produces one of the richest pattern of spectral lines in the infrared. It was therefore an obvious candidate to be explored using the extensive spectroscopic database of the Spitzer satellite, a space-based infrared telescope.

Europe’s Euclid space telescope to launch on July 1

Posted by in categories: cosmology, space travel

The European Space Agency said on Wednesday its space telescope Euclid is scheduled to launch on July 1, blasting off on a mission to shed light on the mysteries of dark matter and dark energy.

The mission will launch on a SpaceX Falcon 9 rocket from Cape Canaveral in Florida, with the broadcast beginning at 1,430 GMT, the ESA said in a tweet.

Euclid was originally planned to ride into space on a Russian Soyuz rocket, but last year Moscow withdrew its launchers in response to sanctions over the invasion of Ukraine.

Intel releases 12-qubit silicon quantum chip to the quantum community

Posted by in categories: computing, quantum physics

Intel – the world’s biggest computer-chip maker – has released its newest quantum chip and has begun shipping it to quantum scientists and engineers to use in their research. Dubbed Tunnel Falls, the chip contains a 12-qubit array and is based on silicon spin-qubit technology.

The distribution of the quantum chip to the quantum community is part of Intel’s plan to let researchers gain hands-on experience with the technology, while at the same time enabling new quantum research.

The first quantum labs to get access to the chip include the University of Maryland, Sandia National Laboratories, the University of Rochester and the University of Wisconsin-Madison.

Researcher uses hydrostatic pressure to understand RNA dynamics

Posted by in category: biotech/medical

Just as space holds infinite mysteries, when we zoom in at the level of biomolecules (one trillion times smaller than a meter), there is still so much to learn.

Rensselaer Polytechnic Institute’s Catherine Royer is dedicated to understanding the conformational landscapes of biomolecules and how they modulate cell function. When biomolecules receive certain inputs, it can cause the atoms to rearrange and the biomolecule to change shape. This change in shape affects their function in cells, so understanding conformational dynamics is critical for drug development.

In research recently published in the Proceedings of the National Academy of Sciences, Royer and her team examined the conformational dynamics of a human transfer ribonucleic acid (tRNA) under high hydrostatic pressure. The high pressure led to an increased population of the tRNA-excited states that normally exist at very low levels, allowing new insights into tRNA function.
