The Biophysical Journal names Denis V. Titov the 2025 Paper of the Year-Early Career Investigator awardee

(Press-News.org) BETHESDA, MD – Denis V. Titov, of the University of California, Berkeley, USA will be honored as the recipient of the Biophysical Journal Paper of the Year-Early Career Investigator Award at the 70th Annual Meeting of the Biophysical Society, held February 21-25 in San Francisco, California. This award recognizes the work of outstanding early career investigators in biophysics. The winning paper is titled “Glycolysis Model Shows that Allostery Maintains High ATP and Limits Accumulation of Intermediates.” The paper was published in Volume 124, Issue 10 of Biophysical Journal.
Glycolysis metabolic pathway is one of the most ancient sets of biochemical reactions that are conserved across all domains of life. This key pathway harnesses the breakdown of glucose to produce energy in the form of ATP and precursors for the rest of energy metabolism. The glycolytic pathway must work at a wide range of ATP demands and be robust to variations in enzyme concentrations and reaction rates. Due to complexity of glycolysis and experimental challenges, much of our understanding of glycolytic regulation has come from mathematical models, but so far these models were scarce and simplified.
Titov and colleagues used a system of differential equations to develop the first detailed biophysical model of glycolysis based on decades of in vitro kinetic data. They solved a difficult problem of estimating 172 parameters from dozens of datasets and found that mass action reactions alone are sufficient to maintain the high and stable energy of ATP hydrolysis. Furthermore, they found that allosteric regulation of several glycolytic enzymes by ATP, ADP and inorganic phosphate is required to prevent uncontrolled accumulation of glycolysis intermediates. This pioneering model will boost quantitative understanding of cell energy metabolism.
“The Paper of the Year is an award that recognizes work by an early career investigator published in the Biophysical Journal,“ said Vasanthi Jayaraman, Editor-in-Chief. “We congratulate Denis V. Titov for his work that provides a detailed and experimentally grounded model of glycolysis. The work sets an important benchmark for the field and will shape how we think about cellular energy metabolism going forward.”
The Biophysical Journal is the Biophysical Society's flagship journal which was first published in 1960 and has been published in partnership with Cell Press since 2009. The journal spans a wide range of subjects and disciplines that provide quantitative insight into fundamental problems at the molecular, cellular, systems, and whole-organism levels.

BETHESDA, MD – When you step outside on a winter morning or pop a mint into your mouth, a tiny molecular sensor in your body springs into action, alerting your brain to the sensation of cold. Scientists have now captured the first detailed images of this sensor at work, revealing exactly how it detects both actual cold and the perceived cool of menthol, a compound derived from mint plants. The research will be presented at the 70th Biophysical Society Annual Meeting in San Francisco from February 21–25, 2026.
The study focused on a protein channel called TRPM8. “Imagine TRPM8 as a microscopic thermometer inside your body,” said Hyuk-Joon Lee, ...

Tokyo, Japan – Researchers from Tokyo Metropolitan University have created a new molecule which carries DNA into biological cells, to treat or vaccinate against illnesses. Many existing options rely on molecules with a strong positive charge, which can cause harmful inflammation. The team overcame this by using a neutral molecule and a new method to bind DNA to it, making it possible to deliver DNA into cells. Successful experiments in mice promise new, more effective therapies.
Over the last few decades, scientists have developed new treatments which deliver genetic information into cells. ...

PROVIDENCE, R.I. [Brown University] — A new study revealed that certain brain regions are more active in people with obsessive-compulsive disorder (OCD) during cognitively demanding tasks. The findings could help inform new ways in which the condition is treated and assessed.
The study, published in Imaging Neuroscience, was conducted by researchers in the laboratory of Theresa Desrochers, an associate professor of brain science and of psychiatry and human behavior at Brown University’s Carney Institute for Brain Science.
Desrochers studies abstract sequential behavior, which is behavior — such ...

Researchers at Duke University’s Nicholas School of the Environment found that ocean saltiness can influence the strength of El Niño, a climate phenomenon that can dramatically affect global weather. The results, published in Geophysical Research Letters in January, could inform development of more precise El Niño forecasts.
El Niño occurs every two to seven years, marked by wetter conditions in some parts of the world and drier weather in others. Its formation depends on weakening ...

Why do some people feel chills when listening to music, reading poetry, or viewing a powerful work of art, while others do not? New research by Giacomo Bignardi and his colleagues from Max Planck Institute for Psycholinguistics (MPI) published in PLOS Genetics reveals that part of the answer lies in our genes.
Charles Darwin once described how hearing an anthem in King’s College Chapel gave him “intense pleasure so that [his] backbone would sometimes shiver.” Vladimir Nabokov (despite his notorious dislike for music) later celebrated the same sensation, calling it ‘the telltale tingle’ required to truly appreciate literary ...

Public misunderstanding about medical aid in dying in the United States falls into two distinct categories – misinformation and uncertainty – and each is driven by different forces, according to Rutgers Health researchers.
Their study, published in the Journal of General Internal Medicine, found that misinformation about legality of medical aid in dying – a voluntary medical practice for terminally ill adults often abbreviated as MAID – is primarily shaped by ideology, while uncertainty is linked to structural barriers such as education level and financial ...

STARKVILLE, Miss.—An article by Mississippi State Professor of Anthropology Molly Zuckerman and her graduate student Lydia Bailey has been published in Science, one of the foremost scientific journals in the world.
Zuckerman and Bailey’s piece examines new evidence from ancient DNA that pushes the origins of diseases closely related to syphilis back more than 5,000 years and strongly supports an American rather than European origin for a close relative of the disease. Drawing on recent paleogenomic discoveries from Colombia and Mexico, the article demonstrates how advances ...
