University of Pennsylvania researchers and colleagues have discovered how plants respond to seasonal flowering cues while protecting the stem cells at their growing tip, enabling continuous reproduction in changing environments.

Scientists have found the first known correlation between latitude and the rate of mimicry evolution in butterflies, consistent with a longstanding theory of biodiversity that can trace its origin to Alfred Russel Wallace, the co-discoverer of evolution by natural selection.

Writing in Nature, a team led by physicists Cory Dean from Columbia University and Jia Li from the University of Texas at Austin has observed a superfluid, which normally remains in constant motion, come to a standstill. “For the first time, we’ve seen a superfluid undergo a phase transition to become what appears to be a supersolid,” said Dean. It’s like water freezing to ice, but at the quantum level.

According to Hui Yang, Gary and Sheila Bello Chair in Industrial and Manufacturing Engineering at Penn State, and Kevin Mekulu, an industrial engineering and operations research doctoral candidate, artificial intelligence (AI) could be used to better understand and detect neurodegenerative diseases like dementia and Alzheimer's. In a Q&A, Yang and Mekulu shared how AI-powered screening methods could contribute to cognitive care, helping clinicians intervene sooner and improve patient outcomes. 

Kennesaw State University professor Lingfeng Tao is leading research that teaches robots how to manipulate objects with greater dexterity and awareness. The research is supported by a $300,000 National Science Foundation (NSF) grant, as well as a $40,000 NVIDIA Academic Grant that provides advanced AI hardware.

Wei Lu's Team at the Institute of High Energy Physics (IHEP) Proposes a Novel Scheme for High-Quality Positron Acceleration Utilizing Nonlinear Beam Loading in the Blowout Regime.

A new study based on long-term monitoring data demonstrates significant differences in growth between nurse sharks off the coast of Miami and those living just across the Gulf Stream.

After maritime shipping emissions were sharply reduced following a mandated switch in fuels, University of Utah atmospheric scientists sprang into action to see how the change would affect cloud formation over North Atlantic. Review of satellite observations and weather data determined few droplets formed, yet the clouds’ ability to reflect sunlight remained surprisingly stable.

Researchers at the University of Rochester’s Institute of Optics have developed a new process that turns ordinary metal tubes unsinkable—meaning they will stay afloat no matter how long they are forced into water or how heavily they are damaged. The researchers describe their process for creating aluminum tubes with remarkable floating abilities in a study published in Advanced Functional Materials. By etching the interior of aluminum tubes, the researchers create micro- and nano-pits on the surface that turn it superhydrophobic, repelling water and staying dry.
