Engineering nature's blueprint: Dendron-based assemblies for chlorophyll's materials

Chlorophyll (a naturally occurring pigment involved in photosynthesis)-inspired molecules hold promise for developing next-generation light-harvesting materials. However, achieving precise control over their assembly is challenging. Researchers have now revealed that attaching dendrons -- branched, tree-like structures -- can aid in self-assembly of chlorophyll's materials. They found that smaller dendrons lead to stacked, fiber-like structures, while larger dendrons create spherical chlorophyll particles,. Read more ›

These wild chimpanzees play as adults to better cooperate as a group

Compared to children, adults don't play as much, but social play into adulthood is considered a universal human trait. Play has a role in building tolerance, cohesion, bonding, and cooperation. By comparison, play in adults of other species has been considered rare, and yet a new study shows that some chimpanzees, like people, continue to play often throughout their entire lives and especially before engaging in acts that require collective...

DNA repair: A look inside the cell's 'repair café'

New research sheds light on how cells repair damaged DNA. For the first time, the team has mapped the activity of repair proteins in individual human cells. The study demonstrates how these proteins collaborate in so-called 'hubs' to repair DNA damage. This knowledge offers opportunities to improve cancer therapies and other treatments where DNA repair is essential. Read more ›

Research highlights the pressures human activities place on tropical marine ecosystems

The tropical coastlines of Southeast Asia are home to some of the most important and biodiverse marine ecosystems on the planet. But as well as being essential to communities along these coastlines, fishing and tourism were found -- in new research conducted by an international study team -- to be among the most damaging from an environmental perspective.
