Alcohol consumption by fathers before conception could negatively impact child development

Scientists at the University of California, Riverside, have explored the relationship between parental alcohol consumption — before conception in the case of fathers and during pregnancy in the case of mothers — and offspring development. In a paper published in Alcoholism: Clinical and Experimental Research, the researchers report that when alcohol-exposed male […]

Cells must age for muscles to regenerate in muscle-degenerating diseases

Exercise can only improve strength in muscle-degenerating diseases when a specific type of muscle cell ages, report a Hokkaido University researcher and colleagues with Sapporo Medical University in Japan. Their findings utilizing mice models were published in the journal Nature Communications. Idiopathic inflammatory myopathies are rare diseases that cause muscle […]
