Your gut’s railway switch: How the “second brain” decides between attack and repair

Researchers discovered that the gut's epithelial cells can translate nerve signals into molecular instructions, such as cytokines, to coordinate immune responses. This system is closely linked to feeding behaviour and daily biological rhythms, suggesting a link between disrupted circadian patterns and 'civilisation diseases' like chron...

Why do we have a consciousness?

Scientists Albert Newen and Carlos Montemayor identify three types of consciousness: basic arousal, general alertness, and reflexive self-consciousness. Birds also demonstrate conscious processing, meeting criteria for theories like the Global Neuronal Workspace theory, and exhibit situational self-consciousness in experiments.

A new cellular model reveals which mutations drive progression to myelodysplastic syndrome and leukemia in patients with GATA2 deficiency

A new humanised model based on induced pluripotent stem cells identifies SETBP1 as a key driver of disease progression. The model shows that secondary mutations impair haematopoietic differentiation and reduce the regenerative capacity of myeloid progenitor cells.

Fishing for phages in Lund University’s Botanical Gardens

The discovery of five new bacteriophages in Lund University's Botanical Gardens' ponds has significant implications for phage research and treatment of bacterial infections. The newly-discovered phages were isolated using a motile E. coli strain, which was specifically designed to attract the viruses.

Blood protein profiles can predict mortality

A new study from the University of Surrey found that elevated levels of five proteins in blood can predict mortality risk. These proteins, which play key roles in disease development, also contributed to increased risk of death within a 5- or 10-year timeframe.

Malaria parasites move on right-handed helices

Researchers from Heidelberg University discovered that malaria parasites use right-handed helices to navigate through tissues, a key finding with implications for improving drug and vaccine testing. The parasite's asymmetrical body plan enables it to control its motion and transition between compartments more efficiently.

Our bodies 'talk,’ listen carefully: College of Public Health researcher helps chronic pain sufferers reduce opioid misuse

Researchers found that mindfulness-based program MORE increased interoceptive awareness, reducing the risk of prescription opioid misuse in individuals with chronic pain. Participants who demonstrated lower trust in their body signals and difficulty regulating attention to bodily sensations were at higher risk for opioid misuse.
