How can the metal content of stars influence the formation of Earth-like exoplanets? This is what a recent study published in The Astronomical Journal hopes to address as an international team of researchers investigated the minimum amount of metals a star can possess (also called metallicity) that are needed for Earth-like planets to form in small orbits like our own. This study holds the potential to help researchers better understand the necessary conditions for Earth-like exoplanets to form, along with gaining new insights into the formation and evolution of other exoplanets.

This research builds off previous studies that hypothesized a correlation between star’s low metallicity and the formation of exoplanets smaller than Saturn or Neptune. For this new study, the researchers used computer models built from exoplanet data obtained by NASA’s Transiting Exoplanet Survey Satellite (TESS) mission to ascertain a metallicity cutoff where the formation of Earth-like exoplanets become impossible. In the end, the researchers indicated that a threshold between-0.75 and-0.5 metallicity is where Earth-like exoplanets can form.

“In a similar stellar type as our sample, we now know not to expect planet formation to be abundant once you pass a negative 0.5 metallicity region,” said Dr. Kiersten Boley, who recently completed her PhD at The Ohio State University and is lead author of the study. “That’s kind of striking because we actually have data to show that now. You don’t want to search areas where life wouldn’t be conducive or in areas where you don’t even think you’re going to find a planet. There’s just a plethora of questions that you can ask if you know these things.”

The MXene class of materials has many talents. An international team led by HZB chemist Michelle Browne has now demonstrated that MXenes, properly functionalised, are excellent catalysts for the oxygen evolution reaction in electrolytic water splitting. They are more stable and efficient than the best metal oxide catalysts currently available. The team is now extensively characterising these MXene catalysts for water splitting at the Berlin X-ray source BESSY II and Soleil Synchrotron in France.

The findings have been published in Journal of Materials Chemistry A (“Enhancing the Oxygen Evolution Reaction activity of CuCo based Hydroxides with V 2 CTx MXene”).

How can microgravity help advance cancer research? This is what an upcoming grant-awarded project sponsored by the International Space Station (ISS) National Lab hopes to address as a team of researchers from the Wake Forest Institute for Regenerative Medicine (WFIRM) have been selected to send samples to the ISS with the goal of observing how microgravity influences cancer growth and their responses to treatment. This project holds the potential to help scientists and cancer researchers develop new methods for combating cancer here on Earth.

“Being selected for this project is an incredible honor and opportunity for our team at WFIRM,” said Dr. Shay Soker, who is the project lead and a professor in the Wake Forest University School of Medicine. “The microgravity environment of the ISS provides a unique setting to study cancer in ways that are not possible on Earth. This research has the potential to unlock new understandings of cancer behavior and lead to more effective treatments.”

Building a robot takes time, technical skill, the right materials – and sometimes, a little fungus.

In creating a pair of new robots, Cornell researchers cultivated an unlikely component, one found not in the lab but on the forest floor: fungal mycelia. By harnessing mycelia’s innate electrical signals, the researchers discovered a new way of controlling “biohybrid” robots that can potentially react to their environment better than their purely synthetic counterparts.

The team’s paper, “Sensorimotor Control of Robots Mediated by Electrophysiological Measurements of Fungal Mycelia,” published Aug. 28 in Science Robotics. The lead author is Anand Mishra, a research associate in the Organic Robotics Lab led by Rob Shepherd, professor of mechanical and aerospace engineering in Cornell Engineering, and the paper’s senior author.
