Study explores interplay between bone, adrenal glands, and aging

Figuring out how the tissues in our bones, adrenal glands, muscle and fat "talk" to each other could help scientists better understand what happens to our skeletons with age, when our bones tend to lose mass and become weaker, leaving us at risk for falls and fractures.

Novel anti-tuberculosis compound targets bacterial membrane protein

Researchers from Heinrich Heine University Düsseldorf (HHU) and the University of Duisburg-Essen (UDE) have together succeeded in identifying and synthesizing a group of molecules that can act against the cause of tuberculosis in a new way. In the scientific journal Cell Chemical Biology, they describe that the so-called callyaerins act against the infectious disease by employing a fundamentally different mechanism compared to antibiotic agents used to date.

Researchers develop highly reactive RNA building blocks for enhanced chip production

An international research team led by the University of Vienna has succeeded in developing a new version of RNA building blocks with higher chemical reactivity and photosensitivity. This can significantly reduce the production time of RNA chips used in biotechnological and medical research. The chemical synthesis of these chips is now twice as fast and seven times more efficient. The results of the research were recently published in the prestigious journal Science Advances.

Scientists capture NMDAR protein's 'twist' motion, key to brain signaling

Proteins are constantly performing a kind of dance. They move and contort their bodies to fulfill specific functions inside our bodies. The NMDAR protein executes an especially hard dance routine in our brains. One wrong step can lead to a range of neurological disorders. NMDAR binds to the neurotransmitter, glutamate, and another compound, glycine. These bindings control NMDAR's dance steps. When their routine is over, the NMDAR opens. This open ion channel generates electrical signals critical for cognitive functions like memory.

Microbes play key role in carcinogenesis

At any given time, over 10 trillion microbes call our guts their home. From breaking down nutrients in our food to strengthening our immunity against pathogens, these microbes play an essential role in how we interact with the world. This includes – as shown in a new study by EMBL researchers and collaborators at the University of Split, Croatia – the way the body responds to carcinogens and develops cancer.

AI model predicts male infertility risk using blood hormone levels

According to a World Health Organization (WHO) study (2017), about half of all infertility is due to men. Semen analysis is considered essential for diagnosis of male infertility, but is not readily available at medical institutions other than those specializing in infertility treatment, and there is a high threshold for receiving it.
