Scientists reveal chemistry behind civet coffee's unique flavor
Researchers in India have analyzed the chemical changes that occur when coffee beans pass through the digestive systems of wild Asian palm civets, explaining the luxury beverage's prized taste. The study highlights higher fat content and lower acidity in these beans compared to regular ones. The findings aim to enable artificial production, avoiding the cruelty of caged civet farming.

Gene-edited pigs resist classical swine fever virus
Scientists have used CRISPR to edit a single gene in pigs, making them fully resistant to classical swine fever, a contagious disease that devastates livestock. This breakthrough could enhance animal welfare, boost productivity, and reduce emissions. The same edit may protect cattle and sheep from related viruses.
Study reveals reasons for birds' dawn chorus
Experiments with zebra finches suggest that darkness suppresses birds' singing motivation overnight, leading to an intense dawn chorus when light arrives. The research also indicates that this singing helps optimize vocal structures. While promising, experts caution that the findings may not fully explain the phenomenon across all species.
