What if we’re not alone on Earth? Why We May Not Be Alone on Earth…

The shadow biosphere is a hypothetical microbial biosphere of Earth that would use radically different biochemical and molecular processes from that of currently known life.

Sketches found inside Leonardo da Vinci’s sketchbooks, show that he had already grasped the essence of Einstein’s 1907 ‘Equivalence Principle’ centuries before the physicist.

Silicon, the standard semiconducting material used in a host of applications—computer central processing units (CPUs), semiconductor chips, detectors, and solar cells—is an abundant, naturally occurring material. However, it is expensive to mine and to purify.

How will materials behave under certain conditions? And how to make materials more robust? These two questions are crucial to design advanced materials for structural and functional components and applications. A close look at the underlying atomic structures and especially their defects is necessary to understand and predict material behavior.

Electrical conductivity, strength and fracture resistance are for example influenced by grain boundaries. It is known that grain boundaries—despite being defects—have their own ordered atomic structures, which can influence or even dominate material properties. However, their experimental observation requires precise and time-consuming atomic resolution imaging and is limited to the investigation of specific, individual cases.

But are these cases generalizable for all metals? A researcher team of the Max-Planck-Institut für Eisenforschung (MPIE) utilized computer simulations to show that the same atomic arrangements occur in a whole group of metals, namely fcc metals, thus proving that the “special cases” investigated in the experiments are not really exotic, but common.

A new study has identified seven spider species previously unknown to science in the depths of Israeli caves, with the surprise finding that they are evolutionarily closer to arachnids found in southern Europe than to their neighbors at cave entrances in Israel.

The peer-reviewed research, published in the Molecular Phylogenetics and Evolution journal, was conducted by scientists from the Hebrew University in Jerusalem and the University of Madison-Wisconsin.

The study “has extensive scientific implications for uncovering the evolution of speciation in caves and the historical, geographic and climatic processes that occurred in Israel,” the Hebrew University said in a statement.

On Wednesday, Qualcomm (NASDAQ: QCOM) unveiled the semiconductor industry’s first advanced-ready 5G modem-RF chip that can be used not only in smartphones, but mixed reality headsets, 5G networks and other areas.

Led by CEO Cristiano Amon, Qualcomm (QCOM) said the Snapdragon X75 5G Modem-RF chip utilizes artificial intelligence thats two-and-a-half times faster than previous AI used and better software to bring faster connections to devices, while also allowing them to get better signal strength, data speed and coverage.

Qualcomm (QCOM) added that the chips can also be used in vehicles, an increasing component of the company’s business, as well as PCs, factories and fixed wireless access networks.

I wanted to test how well endowed is ChatGPT in the field of Longevity. For that matter I asked the following two questions: Which are the most promising therapies which are being developed to significantly extend healthy lifespan in humans using 4,000 characters (about maximum lenght to be readable in one page).

Which are the most promising therapies to achieve epigenetic cellular rejuvenation.

I created a two-page document in PDF with a screenshot of the responses for the two questions, so to show them exactly as they appeared in my laptop (no editing by me whatsoever).
