Director and oceanographer James Cameron said Friday that the design of the imploded Titan submersible was “critically flawed,” calling the construction of the vessel an “insidious” mistake.
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 solar cells in the “Solar cell efficiency tables.” Prior to the record-breaking feat by the NUS team, the best 1 cm2 perovskite solar cell recorded a power conversion efficiency of 23.7%. This ground-breaking achievement in maximizing power generation from next-generation renewable energy sources 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.

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 light years away from Earth—relatively close in astronomical terms. The region is generally invisible to the naked eye, but shines brightly when viewed in infrared wavelengths.
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.
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 – 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.
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.
Most of us don’t think of atoms as having their own unique vibrations, but they do. In fact, it’s a feature so fundamental to nature’s building blocks that a team of University of Washington researchers recently observed and used this phenomenon in their research study. By studying the light atoms emitted when stimulated by a laser, they were able to detect vibrations sometimes referred to as atomic “breathing.”
The result is a breakthrough that may one day allow us to build better tools for many kinds of quantum technologies.
Led by Mo Li, a professor of photonics and nano devices in both the UW Department of Electrical and Computer Engineering and the UW Physics Department, the researchers set out to build a better quantum emitter, or QE, one that could be incorporated into optical circuits.
