SENS Research Foundation works to develop, promote, and ensure widespread access to therapies that cure and prevent the diseases and disabilities of aging by comprehensively repairing the damage that builds up in our bodies over time.
A new study from The University of Texas at Arlington details a novel strategy for how the body clears out dead cells during stress, revealing unexpected roles for well-known stress-response genes—a discovery that could help scientists better understand diseases affecting the immune system, brain and metabolism.
“The body is constantly creating new cells and removing old cells once they die,” said Aladin Elkhalil, lead author of the study and a third-year doctoral student in the lab of Piya Ghose, assistant professor of biology at UT Arlington. “This removal of dead cells is just as important as creating new ones, because if the body is unable to rid itself of dead cells, it can lead to various health problems”
Published in PLOS Genetics, the study was conducted on the roundworm C. elegans by Dr. Ghose, Elkhalil and Alec Whited, another graduate student in the Ghose lab. This tiny, transparent organism is a widely used tool in genetic research because its see-through body allows scientists to observe live cell behavior, including how cells die. The research team took advantage of these unique features in several innovative ways.

The Hong Kong University of Science and Technology (HKUST)-led research team has adopted gyromagnetic double-zero-index metamaterials (GDZIMs) — a new optical extreme-parameter material – and developed a groundbreaking method to control light using GDZIMs. This discovery could revolutionize fields like optical communications, biomedical imaging, and nanotechnology, enabling advances in integrated photonic chips, high-fidelity optical communication, and quantum light sources.
Published in Nature, the study was co-led by Prof. CHAN Che-Ting, Interim Director of the HKUST Jockey Club Institute for Advanced Study and Chair Professor in the Department of Physics, and Dr. ZHANG Ruoyang, Visiting Scholar in the Department of Physics at HKUST.
A culture collection of more than 500 fungal strains from seawater, sediments and seaweeds is helping scientists better understand marine fungi.
How the brain largely maintains its function when neurons are lost—this is what researchers at the University Medical Center Mainz, the Frankfurt Institute for Advanced Studies (FIAS) and Hebrew University (Jerusalem) have deciphered. They show that neuronal networks in the cerebral cortex reorganize within a short period of time, with other nerve cells taking over the tasks of the lost neurons.
These findings could form the basis for future research into natural aging processes and neurodegenerative diseases such as Alzheimer’s or Parkinson’s. The study is published in the journal Nature Neuroscience.
Nerve cells (neurons) are the most important building blocks of the brain. They form the basis for all mental and physical functions such as thinking, feeling, movement, and perception. In the course of life, nerve cells in the brain can be lost for various reasons: They die off due to age-related processes, are damaged by toxins such as alcohol, or neurodegenerative diseases such as Alzheimer’s and Parkinson’s lead to a more rapid progressive loss of neurons.
Quantum dots are microscopic semiconductor crystals developed in the lab that share many properties with atoms, including the ability to absorb or emit light, a technology that Los Alamos researchers have spent nearly three decades evolving. Through carrier multiplication, in which a single absorbed photon generates two electron-hole pairs, called excitons, quantum dots have the unique ability to convert photons more efficiently to energy.
“Our work demonstrates how purely quantum mechanical spin-exchange interactions can be harnessed to enhance the efficiency of photoconversion devices or photochemical reactions,” says Victor Klimov, the team’s principal investigator at the Lab. “This not only deepens our fundamental understanding of quantum mechanical phenomena but also introduces a new paradigm for designing advanced materials for energy applications.”
In this latest research, published in the journal Nature Communications, Los Alamos researchers improved this ability by introducing magnetic manganese impurities into quantum dots. This novel approach to highly efficient carrier multiplication leverages ultrafast spin-exchange interactions mediated by manganese ions to capture the energy of energetic (hot) carriers generated by incident photons and convert it into additional excitons.
