By studying genes that affect cuticle pigmentation in the laboratory fruit fly, researchers were able to identify new genes, mask and clu, that are involved in regulating dopamine levels in the brain. The findings offer new possibilities to restore in people disruptions in dopamine that have been associated with neurological and neuropsychiatric disorders, including addiction, depression, sleep disorders and schizophrenia.
Abdominal fat is not a uniform tissue. A new study from Karolinska Institutet, Steno Diabetes Center Copenhagen, and Helmholtz Munich reveals that fat located close to the large intestine contains an unusually high number of inflammatory fat cells and immune cells. The findings suggest that this tissue is specially adapted to communicate with the immune system in the gut region. The study is published in the journal Cell Metabolism.
Great Bear Rainforest, BC. The Great Bear Lodge on the Central Coast of British Columbia is collaborating with internationally acclaimed science journalist Lesley Evans Ogden to host a nature writing retreat from May 31 - June 4, 2026. Small group size will ensure each participant benefits from individual focus and support, allowing instruction and skill development to be tailored to a range of abilities, from aspiring to experienced writers.
The conservation of genome regulatory elements over long periods of evolution is not limited to vertebrates, as previously thought, but also in echinoderms (invertebrates). This is one of the most notable conclusions of a study published in the journal Nature Ecology & Evolution, which expands our knowledge of the mechanisms governing genomic regulation and biological evolution.
A joint study by Tel Aviv University and the University of Haifa set out to solve a scientific mystery: how a soft coral is able to perform the rhythmic, pulsating movements of its tentacles without a central nervous system. The study’s findings are striking, and may even change the way we understand movement in the animal kingdom in general, and in the corals studied in particular.
Researchers used Google DeepMind’s AlphaFold2 and ProteinMPNN to speed development of antibody-based probes that can be used to see key functions and chemical changes inside living cells as they happen. This AI-driven method is significantly faster than previous manual testing and development approaches, allowing the CSU team to rapidly create and test 19 new potential probes. The work enables continuous imaging of living cells, which may help researchers better understand errors in genetic expression that can lead to cancer and other disorders.
