UIC study of blood stem cells asks: Can we slow aging on a cellular level?

2025-10-16
As our hairs go gray and our muscles weaken with age, our immune system also changes. In particular, the stem cells that become blood or immune cells can develop mutations, potentially leading to cancers or other dysfunctions. Researchers at the University of Illinois Chicago have discovered an important cellular mechanism that drives this aging: the lack of a protein called platelet factor 4, whose levels decrease with age, they report in the journal Blood. What’s more, adding this protein to old blood cells reversed these signs of aging, which points to a promising therapeutic target for preventing ...

Palm oil isn’t necessarily less sustainable than other oils, say conservationists

2025-10-16
Palm oil isn’t inherently bad, and olive oil isn’t inherently good, conservation scientists say in an opinion paper publishing October 16 in the Cell Press journal Cell Reports Sustainability. They argue that the vegetable oil industry is haunted by narratives and myths about different types of oil crops, but the reality is much more nuanced. Almost all oils—including soybean, olive, coconut, and sesame oil—are associated with biodiversity and human rights issues in some contexts, depending on crop management and supply chains. The researchers call ...

Circularly polarized luminescence enhancement in rare-earth MOFs due to framework chirality and host–guest energy transfer

2025-10-16
Chiral metal-organic frameworks (CMOFs) represent ideal platforms for circularly polarized luminescence (CPL). Incorporating rare-earth ions into MOFs enhances their luminescence via the antenna effect. Chiral imidazolium carboxylic ligands serve as excellent chiral building blocks for CMOFs. These ligands not only sensitize lanthanide ion emission through the antenna effect but also transfer chirality to the framework through coordination, enabling CPL. Their cationic nature imparts a positive charge to the framework channels, facilitating the immobilization of anionic guests through host-guest interactions. This enables modulation ...
