In animal battles, cheaters can win

A new study reveals that animals use cheap tissues like chitin to build their weapons, allowing them to deceive opponents and gain advantages in battles. This tactic is used by species such as snapping shrimps and fiddler crabs, which can exaggerate their size and strength through clever deception.

Perspectives of patients in clinical trials often not considered

Many pragmatic trials fail to collect patient-reported data on experience, burden of disease, and quality of life. Despite this, the authors suggest that including patient-reported outcomes can provide valuable insights into patient well-being. The study urges researchers to prioritize patient-centered approaches in clinical trials.

Important step towards fasting-based therapies

Researchers at Helmholtz Munich have discovered a crucial link between the immune system and metabolic response to fasting. By examining liver cells and immune cells, they found that immune cells can directly influence the effect of fasting on metabolism through a key molecule called the glucocorticoid receptor.

Risk factors linked to anxiety disorders differ between men and women during the pandemic

A Canadian study found that the pandemic-related risk factors for anxiety differ between men and women, with 13.6% of Canadians experiencing clinically significant levels of Generalized Anxiety Disorder (GAD). Men's high anxiety was linked to exposure to COVID-19 misinformation, while women's anxiety was tied to precarious employment.

Immune cells leave fingerprints on tumors metastasized to the brain offering clues to future therapies

Scientists analyzed over 100,000 cells from 15 human brain metastases and identified two functional archetypes of metastatic cells, each containing both immune and non-immune cell types. These archetypes work together within single cells to shape inflammatory and proliferative processes co-existent in each metastatic tumor.
