With the help of newly identified bones, an enigmatic 3.4-million-year-old hominin foot found in 2009, is assigned to a species different from that of the famous fossil Lucy providing further proof that two ancient species of hominins co-existed at the same time and in the same region.

A study by researchers at the University of Wisconsin–Madison has revealed a previously unknown pathway plants use to detect gravity and orient the direction they grow in. Publishing in Proceedings of the National Academy of Sciences, the study may one day open the door for improvements in crop cultivation.

Over the last few years, systems and applications that help visually impaired people navigate their environment have undergone rapid development, but still have room to grow, according to a team of researchers at Penn State. The team recently combined recommendations from the visually impaired community and artificial intelligence (AI) to develop a new tool that offers support specifically tailored to the needs of people who are visually impaired. 

A massive, multi-year scientific expedition determined that land use on tropical islands can shape water quality in lagoons and that rainfall can be an important mediator for connections between land and lagoon waters. The scale of this research is sigificant: the researchers assessed at algal tissue nutrients, water chemistry, and microbial communities at nearly 200 sites around the island of Mo‘orea, French Polynesia, and repeated this sampling over multiple years.

Florida State University oceanographers have discovered a significant connection between small-scale microbial processes and ecosystem-wide dynamics, offering new insights into the mechanisms driving marine carbon storage.

In an effort to reveal the inner workings of a protein that serves as a cell’s damage detection system, scientists at Johns Hopkins and the Ludwig-Maximilians-University Munich (LMU) have published what is believed to be the first 3D details of the ZAK protein’s structure. 

Lehigh University researcher Hannah Dailey is leading a new international collaboration to improve predictions of how bone fractures heal. Supported by the U.S. National Science Foundation and the Swiss National Science Foundation, the four-year project partners with the AO Research Institute Davos (ARI) to develop computational models that combine mechanical factors—such as implant stiffness and loading patterns—with biological processes that vary from patient to patient. Using ARI’s extensive imaging library documenting fracture healing in sheep, the team will build probabilistic models capable of forecasting how recovery will progress. The models will ultimately be integrated into ARI’s online training platform to help surgeons understand how implant choices and rehabilitation strategies influence healing. Long term, the goal is to enable patient-specific simulations that help clinicians identify complications earlier and make more informed treatment decisions.

A new study by researchers at the University of Wisconsin–Madison provides the first empirical evidence connecting the chromosomal location of genes to natural selection, indicating the arrangement of genes can influence how quickly populations can adapt to rapid environmental change.
