Fifty years since its discovery, scientists have finally worked out how a molecular machine found in mitochondria, the ‘powerhouses’ of our cells, allows us to make the fuel we need from sugars, a process vital to all life on Earth.
Scientists at the Medical Research Council (MRC) Mitochondrial Biology Unit, University of Cambridge, have worked out the structure of this machine and shown how it operates like the lock on a canal to transport pyruvate – a molecule generated in the body from the breakdown of sugars – into our mitochondria.
Known as the ...
Research identifies key enzyme target to fight deadly brain cancers
2025-04-18
COLUMBUS, Ohio – Researchers have found that targeting an enzyme called PGM3 can help stop the growth of glioblastoma, the most dangerous type of brain tumor.
This enzyme plays a vital role in the hexosamine synthesis pathway, which is involved in the processes of protein and lipid glycosylation that allow tumors to rapidly grow. Lipid glycosylation is a process where sugar molecules attach to fats (lipids) in the body.
Researchers with The Ohio State University Comprehensive Cancer Center – Arthur G. James and Richard J. Solove Research Institute believe that targeting PGM3 can reduce tumor growth and eliminate glioblastoma cells.

Researchers from Radboud university medical center have demonstrated that an existing drug can revive immune cells that are not functioning correctly. These findings provide leads for further research in patients admitted to the intensive care unit (ICU) with sepsis.
Twenty percent of global deaths are associated with sepsis, and it is the leading cause of death in ICUs. Sepsis is characterized by organ failure, for instance of the kidneys or lungs, caused by a dysregulated immune response to an infection. Patients with ...
Soft brainstem implant delivers high-resolution hearing
2025-04-18
Over the last couple of decades, many people have regained hearing functionality with the most successful neurotech device to date: the cochlear implant. But for those whose cochlear nerve is too damaged for a standard cochlear implant, a promising alternative is an auditory brainstem implant (ABI). Unfortunately, current ABIs are rigid implants that do not allow for good tissue contact. As a result, doctors commonly switch off a majority of the electrodes due to unwanted side effects such as dizziness or facial twitching—leading most ...
Uncovering the structural and regulatory mechanisms underlying translation arrest
2025-04-18
Proteins form the structural and functional backbone of the cell, and any perturbation in their synthesis can disrupt normal cellular functions. The DNA blueprint is carefully read, transcribed, and translated into functional proteins through a tightly regulated process. The ‘ribosome’ plays a crucial role in orchestrating the translation of the messenger RNA transcript by assembling amino acids into the corresponding polypeptide sequence. Ribosomal functions beyond protein synthesis have been uncovered over the years, revealing its role ...
