Potentially very useful discovery.

Scientists have solved a decades-long puzzle and unveiled a near unbreakable substance that could rival diamond as the hardest material on Earth. The research is published in the journal Advanced Materials.

Researchers found that when carbon and nitrogen precursors were subjected to extreme heat and pressure, the resulting materials—known as carbon nitrides—were tougher than cubic boron nitride, the second hardest material after diamond.

A recent study published in The Astrophysical Journal and presented at this week’s American Geophysical Union Annual Meeting 2023 examines how 17 exoplanets could harbor interior oceans of liquid water, and possibly even geysers, much like two moons within our solar system, Europa and Enceladus. This study was conducted by a team of researchers across academia and multiple research institutions and holds the potential to help scientists better understand the prospects and conditions for finding life beyond our solar system, including the examination of how life could form outside of a star’s habitable zone (HZ).

“Our analyses predict that these 17 worlds may have ice-covered surfaces but receive enough internal heating from the decay of radioactive elements and tidal forces from their host stars to maintain internal oceans,” said Dr. Lynnae Quick, who is a planetary geophysicist at NASA’s Goddard Space Flight Center and lead author of the study. “Thanks to the amount of internal heating they experience, all planets in our study could also exhibit cryovolcanic eruptions in the form of geyser-like plumes.”

Realizing the potential of Smart Cities will require public-private cooperation and security by design.

The idea of smart cities is starting to take shape as the digital era develops. A city that has developed a public-private infrastructure to support waste management, energy, transportation, water resources, smart building technology, sustainability, security operations and citizen services is referred to as a “smart city”. Realizing the potential of Smart Cities will require public-private cooperation and security by design.

Evolution has produced a range of diverse proteins, and now a generative model called Chroma can expand that set by allowing the user to design new proteins and protein complexes with desired properties and functions.

A stroke happens when blood flow is lost to part of the brain. Your brain cells cannot get the oxygen and nutrients they need from blood, and they start to die in a few minutes. This can cause lasting brain damage, long-term disability, or even death.

A stroke can occur when an obstruction such as a blood clot travels from another part of the body and lodges inside an artery in the brain.

When an arterial wall becomes damaged, various types of emboli, or obstructions, can form. Emboli can be made up of various substances such as platelets, elements in the blood that help it clot, blood clots that form elsewhere and pass to the damaged area, cholesterol, or a combination of things.

Moore’s Law predicts that computers get faster every two years because of the evolution of semiconductor chips.

Researchers at Tohoku University and the University of California, Santa Barbara, have shown a proof-of-concept of energy-efficient computer compatible with current AI. It utilizes a stochastic behavior of nanoscale spintronics devices and is particularly suitable for probabilistic computation problems such as inference and sampling.

The team presented the results at the IEEE International Electron Devices Meeting (IEDM 2023) on December 12, 2023.

In December 2022, NASA’s MAVEN mission observed a rare solar event causing the solar wind to “disappear.” This led to significant changes in Mars’ atmosphere and magnetosphere, including their expansion. Scientists, astounded by the data, formed a working group to study this phenomenon. Credit: SciTechDaily.com.

NASA ’s MAVEN detected a unique solar event that drastically affected Mars ’ atmosphere, offering vital insights into the planet’s interaction with solar phenomena.
