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 long-held belief that these types of grasses show a weak response to changes in CO2 concentration. The findings highlight a previously underestimated factor influencing the transformation of savannah ecosystems globally.
Savannah Grass Growth in Dry Conditions is Boosted by Increased CO2 Levels
A comprehensive study, integrating results from 70 diverse experiments and three decades of real-world field data, has demonstrated that elevated carbon dioxide concentrations can invigorate the growth of C4 grasses, especially when water resources are scarce. This research challenges the prevailing notion that C4 grasses exhibit a minimal reaction to shifts in atmospheric CO2. The study unveils a crucial, yet previously overlooked, factor driving ecological changes across the world's savannahs.

Analysis of 70 experiments and 32 years of field observations shows that increasing the amount of carbon dioxide enhances the growth of the C4 group of grasses when water is limited. These findings challenge the assumption that C4 grasses respond weakly to changes in carbon dioxide level, and reveal an overlooked driver of change across the world’s savannahs.

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
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 with
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
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
