New class of hydrogen sulfide donor molecules

Posted · Add Comment

Researchers have designed molecules with the potential to deliver healing power to stressed cells — such as those involved in heart attacks. The research, at a cellular level in the lab, involves organic molecules that break down to release hydrogen sulfide when triggered by oxidative stress.

Jawing away: Bahama pupfish study identifies candidate genes driving food-niches

Posted · Add Comment

Scientists have studied three closely related pupfish species peacefully co-existing because each, through subtle jaw size differences, has rapidly carved out its own food niche within the last 10,000 years. They have matched DNA changes with differences in jaw size to uncover candidate genes responsible, along with evidence supporting the role of large-effect alleles in […]
