Chimpanzees join their close bond partners - related group members and friends - to battle rivals. Credit: Liran Samuni, Taï Chimpanzee Project Chimpanzees, one of the closest relatives of humans, cooperate on a group level—in combative disputes, they even cooperate with group members to whom they are not related. Those involved in fights with...
Credit: CC0 Public Domain Macrophages—immune cells that both fight infections and fix the damage they cause—are often placed into two categories: those that increase inflammation (known as "M1") to attack, and those that decrease inflammation to begin the healing process ("M2"). Researchers in the lab of Kathryn Miller-Jensen, associate professor of biomedical engineering and...
Jupiter's moon Ganymede is the largest planetary satellite in the solar system. It's also one of the most intriguing: Ganymede is the only moon with its own magnetic field, it is the most differentiated of all moons, and it likely possesses a subsurface ocean of liquid water. It was studied by the early Jupiter...
Pictorial representation of joint experimental and computational study of materials. The study utilized the Advanced Photon Source (upper panel) and Argonne Leadership Computing Facility (lower panel). The team addressed the atomistic structure of interfaces, which are ubiquitous in materials.

Schematic illustration of CEA detection in saliva. Eu2O3 NCs and disposable syringe filter equipped with nitrocellulose membrane are employed as nanoprobes and bioassay platform, respectively. The whole assay can be carried out within 10 min, including incubation, labeling, and washing procedures, which allows both quantitatively time‐resolved (TR) and qualitatively visual detection of CEA.Advanced Science...
Credit: Pixabay/CC0 Public Domain Most legume species have compound leaves with multiple joined units termed leaflets, and the geometry of leaflets (the spatial structure and organization of leaflets) largely determines the compound leaf shape, which has been broadly recognized in model compound-leafed species. Previous studies mainly focused on the role of the pulvinus in...
Credit: CC0 Public Domain Yield, purity and integrity, of microbial DNA extracted from digesta samples is crucial for downstream analysis of amplicon sequencing. These markers of quality are influenced by chemical and mechanical lysis. However, contributions of chemical and mechanical lysis have not been investigated in DNA extraction methodology. Recently, researchers from the Institute...

Marco Rubio holds rally in front of the Space Shuttle Pathfinder exhibit at the U.S. Space & Rocket Center in Huntsville, Ala. In an announcement Tuesday, Jan. 19, 2021, the U.S. Space & Rocket Center said it will restore the world's only full-sized...
The image of a female Asian elephant in a tea plantation on the fringes of KazirangaNational Park in India, bordering the Eastern Himalaya biodiversity hotspot, exemplifiespotential impacts to endangered species conservation in cropland-impacted parks. The elephant in the image is mock charging at rescuers extracting her calf from a trench at the edge of...
The interior of a termite nest shows complex, interconnecting floors and ramps. Credit: Guy Theraulaz/Harvard SEAS Following a series of studies on termite mound physiology and morphogenesis over the past decade, researchers at the Harvard John A. Paulson School of Engineering and Applied Sciences have now developed a mathematical model to help explain how...
