“The changes we see preserved in the rock record are driven by large-scale changes in the Martian environment,” said Dr. David Paige. “It’s cool that we can see so much evidence of change in such a small geographic area, which allows us extend our findings to the scale of the entire crater.”

NASA’s Perseverance (Percy) rover has been exploring Jezero Crater on Mars since it landed there in February 2021. During that time, it has made some truly remarkable discoveries and helped us better understand the history of the Red Planet and whether it could have once supported life long ago. It has long been hypothesized that Jezero Crater was once home to a massive lake of liquid water billions of years ago, and a recent study published in Science Advances by the University of California, Los Angeles (UCLA) and the University of Oslo might have confirmed the most precise data to date regarding this hypothesis.

For the study, the researchers used the RIMFAX ground penetrating radar, which can take radar images up to 20 meters (65 feet) below Percy’s location, to analyze the geologic layers underneath the rover. These images gave researchers a first-time glimpse into the former crater floor that has been slowly buried over vast periods of geologic time.

The ancestral Maya lived in better harmony with the environment and kept water clean naturally. We can learn from them.

The discovery of an ancient lake bed beneath the Perseverance rover’s location on Mars could mean the robotic scout has already scraped up microbial fossils. But we won’t know for sure until we fetch the sample.

Nakamura, who was awarded the Nobel Prize for his pioneering work on the development of blue light-emitting diodes (LEDs), believes that his company can harness their semiconductor expertise to create a secure pathway for achieving nuclear fusion and transforming it into a commercially viable venture.

The precise details of the approach remain undisclosed as Blue Laser Fusion currently has a pending patent.

However, Nakamura is confident in the feasibility of constructing rapid-fire lasers and envisions the establishment of a one-gigawatt generating reactor in either Japan or the US by the end of the decade. Prior to that milestone, the company intends to construct a small-scale experimental plant in Japan before the conclusion of the next year, as reported by Nikkei.

What happens when you expose tellurite glass to femtosecond laser light? That’s the question that Gözden Torun at the Galatea Lab at Ecole Polytechnique Federale de Lausanne, in collaboration with Tokyo Tech scientists, aimed to answer in her thesis work when she made the discovery that may one day turn windows into single material light-harvesting and sensing devices. The results are published in Physical Review Applied.

Interested in how the atoms in the tellurite glass would reorganize when exposed to fast pulses of high energy femtosecond laser light, the scientists stumbled upon the formation of nanoscale tellurium and tellurium oxide crystals, both semiconducting materials etched into the glass, precisely where the glass had been exposed. That was the eureka moment for the scientists, since a semiconducting material exposed to daylight may lead to the generation of electricity.

“Tellurium being semiconducting, based on this finding we wondered if it would be possible to write durable patterns on the tellurite glass surface that could reliably induce electricity when exposed to light, and the answer is yes,” explains Yves Bellouard who runs EPFL’s Galatea Laboratory. “An interesting twist to the technique is that no additional materials are needed in the process. All you need is tellurite glass and a femtosecond laser to make an active photoconductive material.”
