The inner workings of our planet are getting weirder.

For generations, scientists have probed the structure and composition of the planet using seismic wave studies. This consists of measuring shock waves caused by earthquakes as they penetrate and pass through the Earth’s core region. By noting differences in speed (a process known as anisotropy), scientists can determine which regions are denser than others. These studies have led to the predominant geological model that incorporates four distinct layers: a crust and a mantle (composed largely of silicate minerals) and an outer core and inner core composed of nickel-iron.

According to seismologists from The Australian National University (ANU), data obtained in a recent study has shed new light on the deepest parts of Earth’s inner core. In a paper that appeared in Nature Communications, the team reports finding evidence for another distinct layer (a solid metal ball) in the center of Earth’s inner core — an “innermost inner core.” These findings could shed new light on the evolution of our planet and lead to revised geological models of Earth that include five distinct layers instead of the traditional four.

Physicists at the University of Cincinnati have contributed to an international experiment on strange metals made from an alloy of ytterbium, a rare earth metal. The study involved firing radioactive gamma rays at the strange metal to observe its unusual electrical behavior. The experiment revealed unusual fluctuations in the strange metal’s electrical charge, furthering the understanding of the bizarre behavior of strange metals that operate outside the normal rules of electricity.

International team finds unusual electrical behavior in material that holds promise for new technology.

Physicists at the University of Cincinnati (UC) are learning more about the bizarre behavior of “strange metals,” which operate outside the normal rules of electricity.

Did peptides precede life on Earth? Should we be looking for their biosignatures on Mars?

If you think of DNA in correspondence terms, it writes instructions. RNA picks up the instructions and delivers them to a recipient in the cell. The instructions contain a recipe and what follows is the filling of it producing a protein molecule explicitly designed for the required task.

But before all of the above ever could have happened there had to be something with simpler chemistry. A research team at Rutgers University believes that what first emerged was probably a peptide containing the element nickel. They have named it Nickelback, not to be confused with a Canadian rock band of the same name. This Nickelback peptide consists of two bound nickel atoms which exhibit both stability and activity in terms of reacting with surrounding chemistry. Such a peptide is capable of redox reactions that transfer electrons from one chemical substance to another and is essential as the first stage on the way to life.

The machines could help to “drastically increase the efficiency of the farming industry.”

In farming, weeds can strangle crops and destroy yields. Unfortunately, spraying herbicides to deal with the intrusive plants pollutes the environment and harms human health and there simply aren’t enough workers to tackle all the weeds by hand.

A new startup called FarmWise has come up with a solution: autonomous weeding robots that use artificial intelligence to cut out weeds while leaving crops untouched, according to an MIT report published on Thursday.

It will be a free addition to the Grammarly service.

GrammarlyGO, a contextually aware assistant powered by generative artificial intelligence (AI), has been unveiled by Grammarly, a U.S. cloud-based typing assistant. GrammarlyGO will be increasing productivity by altering the way individuals and organizations communicate and complete work, according to a blog by the company published on Wednesday. “It uses generative AI to help people and businesses succeed with on-demand communication assistance, whether they are starting from scratch or revising an existing piece of writing,” said the press release.
