Critical Zone Processes Limit Alkalinity Export from Natural Basaltic Systems
Observations from natural volcanic watersheds reveal a significant attenuation of alkalinity fluxes. As water travels through the entire reactive path from soil to the river, there is a notable reduction in the amount of alkalinity that is exported. This indicates that processes occurring within the critical zone play a limiting role in the overall export of alkalinity.

Tidal tomography reveals a thermal anomaly beneath Mars’s crustal dichotomy
Recent analysis of tracking data from Mars orbiters has uncovered time-varying gravitational behavior that illuminates the structure beneath the Martian crustal dichotomy. This analysis points to the persistence of a significant thermal anomaly, estimated to be between 200–400 °C, within the present
Primate-Specific Regulation of the Human Glycosphingolipid Gatekeeper UGCG
Researchers have elucidated the cryogenic electron microscopy (cryo-EM) structures of full-length human UGCG. This crucial enzyme acts as a gatekeeper, controlling the extent and variety of glycosphingolipids. The study reveals that UGCG employs a catalytic mechanism that does not require meta
Savannah Grass Growth Boosted by Increased CO2 in Dry Conditions
New scientific analysis, combining data from 70 experiments and 32 years of field observations, indicates that higher carbon dioxide (CO2) levels can significantly stimulate the growth of C4 grasses, particularly in environments with limited water availability. This discovery contradicts the lo
Asymmetric Prefrontal Representations for Leader–Follower Dynamics
When mice cooperate, they naturally adopt distinct leader and follower roles. Research indicates that the medial prefrontal cortex plays a crucial role in processing these role dynamics. Specifically, this brain region is involved in creating an egocentric map that represents the social value
Human Brain Organoids Track Time for Years
For more than five years, human brain organoids have been cultivated, revealing that brain cells can continue to develop and mark the passage of time. These organoids follow internal biological timelines, even when grown outside the human body, showcasing a remarkable capacity for sustained ma
UFC 330: Makhachev vs. Machado Garry Weigh-In Results
The official weigh-ins for UFC 330, scheduled for Saturday, August 15th, from the Xfinity Mobile Arena in Philadelphia, Pennsylvania, have concluded. The event is highlighted by two championship bouts. In the main event, UFC welterweight champion Islam Makhachev will defend his title agai
