Uncontrolled hypertension: A persistent threat to global health

In the United States and worldwide, cardiovascular disease is the leading avoidable cause of premature death and disability. Primarily heart attacks and stroke, cardiovascular disease accounts for more than 900,000 annual deaths nationally and about 10 million deaths globally.

New studies reveal common DNA replication mechanisms in humans and yeast

Humans and baker's yeast have more in common than meets the eye, including an important mechanism that helps ensure DNA is copied correctly, reports a pair of studies published in the journals Science and Proceedings of the National Academy of Sciences.

Novel electrical impedance technique enhances drug testing for cardiac safety

When developing new drugs, understanding their effects on ion channels in the body, such as the human ether-a-go-go-related gene (hERG) ion channel found in neurons and heart muscle cells, is critical.

High-frequency eccentric resistance training decreases passive muscle stiffness

Resistance, or weight training, is widely recommended in sports and rehabilitation as an effective exercise to increase muscular strength and size. This form of exercise involves applying resistance to muscle contraction to build strength. However, some practitioners believe resistance training can increase passive muscle stiffness over time.

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.

Masking policies prevalent in top cancer centers amid winter COVID wave

Nearly half of the nation's National Cancer Institute (NCI)-designated cancer centers required universal masking in key clinical areas during the winter 2023-2024 COVID-19 surge, according to a study by Tulane University researchers.

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.
