Scientific racism's long history mandates caution

Anthropologist Nina Jablonski warns of the dangers of using genomic knowledge to separate people based on genetic endowment or physical features, as it can lead to a new form of 'separate but equal.' She advocates for a more nuanced approach that considers human genetic admixture and individual variability.

Penn study: Topiramate reduces heavy drinking in patients seeking to cut down on alcohol consumption

A study by Penn Medicine found that topiramate significantly reduced heavy drinking days among patients seeking to curb their alcohol consumption. The medication showed promise as a treatment option for problem drinkers, particularly those with a specific genetic makeup linked to its efficacy.

Clinical trial success influenced by biomarker- and receptor-targeted therapies in NSCLC

The cumulative success rate for new agents in advanced NSCLC is lower than industry estimates, but biomarker- and receptor-targeted therapies substantially increase success rates. Biomarker-targeted therapy shows a 62% cumulative success rate, nearly six times higher than non-biomarker targeted trials.

Inside out at the 2014 AAAS meeting: The impact of gut flora on diabetes and obesity

Recent research highlights the critical role of gut flora in diabetes and obesity, with studies suggesting a strong connection between the two. The CommHERE consortium, comprising nine European institutions, has brought together leading experts to discuss their findings on the impact of gut microbiota on metabolic diseases.

Rice's carbon nanotube fibers outperform copper

Carbon nanotube-based fibers have been shown to carry electrical current up to four times that of copper wires of the same mass. The fibers' ability to transmit current makes them ideal for lightweight power transmission in aerospace applications, where weight is a significant factor.
