Loneliness among emerging adults increased slightly

A recent study found that loneliness among emerging adults (18-29 years old) has increased by about 0.56 standard deviations on the UCLA Loneliness Scale over a 43-year period. This slight increase is considered a warning signal for the need to design prevention and intervention measures against loneliness.

Controlling the metabolism of cancer cells

Researchers at Leipzig University have discovered that cancer cells need the succinate receptor to control their metabolic rate. The receptor is found on the surface of various types of tumors and plays a crucial role in the survival of cancer cells.

Heart disease-protective diabetes drug not used equitably, study finds

A recent study found significant inequities in the use of GLP-1 receptor agonists (GLP-1 RA), a medication typically used for treating diabetes, among different racial and ethnic groups. The study, published in JAMA Health Forum, showed that Black patients were 19% less likely to have a GLP-1 RA prescription compared to white patients.

Meta-analysis of two types of molecular stresses reveals common factors

Researchers from Hiroshima University analyzed 839 collections of genetic material to identify common features of oxidative stress. They found two genes, CRIP1 and CRIP3, downregulated during oxidative stress, suggesting a relationship with zinc homeostasis. The study also identified shared biological processes between the two types of...

Magnetic ‘hedgehogs’ could store big data in a small space

Researchers at Ohio State University discovered a new zoo of magnetic patterns that can store big data in a small space, using a material called manganese germanide. The discovery could lead to next-generation data storage with increased energy efficiency.

New imaging technique for early detection of blood trauma

A new imaging technique can detect early signs of blood trauma in red blood cells, which could aid in the development of markers to prevent damage. The technique, developed by researchers at Shibaura Institute of Technology and Griffith University, uses high-speed cameras to visualize changes in RBC shape under stress.

New smart-roof coating enables year-round energy savings

Scientists developed an all-season smart-roof coating that automatically switches between cooling and heating, outperforming commercial cool-roof systems in energy savings. The technology uses vanadium dioxide to regulate its rate of radiative cooling, overcoming the problem of overcooling in winter.

First double-lung transplant after COVID-19 performed in Portugal
