Considered the power generators of the cell, mitochondria convert oxygen and nutrients into chemical energy for the cell that fuels metabolic activities.
Mitochondrial dysfunction has been associated with many diseases, including Alzheimer's, cancer and diabetes, although its exact role in the development of these diseases remains controversial.
The new T-R01 program was specifically created under the NIH Roadmap for Medical Research to support exceptionally innovative, high risk, original or unconventional research projects that have the potential to transform a field of science. The selected projects tend to be inherently risky, but if successful, can profoundly impact a broad area of biomedical research.
Cohen’s bold proposal will test the paradigm-shifting hypothesis that previously unrecognized molecules, he dubbed “mitochondrial-derived peptides” (MDPs), play an earlier unappreciated role in the regulation of cellular and organismal function, and that disregulation of MDPs is important in disease development.
Likewise, understanding the role of MDPs may lead to development of new therapeutic and diagnostic targets. Since Alzheimer’s, cancer and diabetes particularly affect the elderly, these findings could have a significant impact as the world’s aging population continues to grow. The first of these agents, which Cohen named “small humanin-like peptides,” have already demonstrated promise in animal models of diabetes and cancer.
Cohen was one of only 42 researchers nationwide chosen for the T-R01 award. He also serves as chief of endocrinology at the Mattel Children's Hospital UCLA, as well as co-director of the UCSD/UCLA Diabetes and Endocrinology Research Center.

The world's highest gain high power laser amplifier - by many orders of magnitude - has been developed in research led at the University of Strathclyde.
The researchers demonstrated the feasibility of using plasma to amplify short laser pulses of picojoule-level energy up to 100 millijoules, which is a 'gain'...
Staphylococcus aureus is a feared pathogen (MRSA, multi-resistant S. aureus) due to frequent resistances against many antibiotics, especially in hospital infections. Researchers at the Paul-Ehrlich-Institut have identified immunological processes that prevent a successful immune response directed against the pathogenic agent. The delivery of bacterial proteins with RNA adjuvant or messenger RNA (mRNA) into immune cells allows the re-direction of the immune response towards an active defense against S. aureus. This could be of significant importance for the development of an effective vaccine. PLOS Pathogens has published these research results online on 25 May 2017.
Staphylococcus aureus (S. aureus) is a bacterium that colonizes by far more than half of the skin and the mucosa of adults, usually without causing infections....
Physicists from the University of Würzburg are capable of generating identical looking single light particles at the push of a button. Two new studies now demonstrate the potential this method holds.
The quantum computer has fuelled the imagination of scientists for decades: It is based on fundamentally different phenomena than a conventional computer....
An international team of physicists has monitored the scattering behaviour of electrons in a non-conducting material in real-time. Their insights could be beneficial for radiotherapy.
We can refer to electrons in non-conducting materials as ‘sluggish’. Typically, they remain fixed in a location, deep inside an atomic composite. It is hence...
Two-dimensional magnetic structures are regarded as a promising material for new types of data storage, since the magnetic properties of individual molecular building blocks can be investigated and modified. For the first time, researchers have now produced a wafer-thin ferrimagnet, in which molecules with different magnetic centers arrange themselves on a gold surface to form a checkerboard pattern. Scientists at the Swiss Nanoscience Institute at the University of Basel and the Paul Scherrer Institute published their findings in the journal Nature Communications.
Ferrimagnets are composed of two centers which are magnetized at different strengths and point in opposing directions. Two-dimensional, quasi-flat ferrimagnets...
