MIT neuroscientists have found striking evidence that language and logical reasoning are powered by separate systems in the brain. Even people with severe language impairments caused by stroke were able to solve challenging logic puzzles as well as people without those impairments, while brain scans showed that language-processing regions stayed largely quiet during reasoning tasks.

Marine heatwaves are emerging as a threat not just to coral reefs and fisheries, but to human health and well-being. Researchers warn that unusually hot oceans can fuel stronger storms, trigger harmful algal blooms, reduce seafood supplies, disrupt livelihoods, and contribute to anxiety, grief, and depression in coastal communities.

Senescence, which is defined as a state of stable cell cycle arrest, can occur in all tissues of the body. The surveillance and clearance of senescent cells by the immune system is necessary for tissue homeostasis; when this immune surveillance does not occur efficiently, for example, during tumorigenesis and ageing, it has pathological consequences. For example, if the immune clearance of senescent cells is evaded, such as through recruitment of immunosuppressive cells, expression of immune...

CONCLUSION: Isoorientin alleviates age-related bone loss by suppressing TLR4-mediated inflammation, reducing osteoclast activation, and restoring impaired osteogenesis. These findings identify isoorientin as a promising therapeutic candidate for age-associated osteoporosis.
