A study of ostrich eggshell bead exchange reveals that relationships among hunter-gatherer groups existed across hundreds of kilometers in late Middle Stone Age southern Africa. The size of the network provided access to high ecological diversity and offered a social strategy against scarcity.
Researchers at UNIST have developed flexible and transparent solar cells that can absorb reflected light, increasing their efficiency. The new solar cell structure takes advantage of the theoretical light absorption mechanism to recycle reflected light, enabling it to maintain over 95% initial efficiency even after bending tests.
Researchers at Ludwig-Maximilians-Universität München identified a signaling pathway enabling mitochondria to transmit distress signals to the surrounding cytosol. This pathway involves enzymes OMA1 and DELE1, which trigger cellular responses to stress, potentially opening new therapeutic approaches for age-related diseases.
Researchers discovered diverse forms of Photosystem I in cyanobacteria and algae, including a specialized dimer in Anabaena and a minimal form in Dunaliella. These findings suggest new energy pathways, pigment binding sites, and phospholipids, providing insight into photosynthesis beyond traditional textbook descriptions.
Researchers at RHIC have made precision measurements of hypertriton and antihypertriton binding energy and mass, shedding light on symmetry violations in neutron stars. The results could have significant implications for understanding astrophysical phenomena involving strange quarks.
Researchers found that premature babies can catch up with their immune systems after birth, equivalent to those born at term. The study suggests that preterm and term infants converge in a similar time frame for immune development, and that early identification of infection risk can lead to improved outcomes.
A University of Utah Health study found that poor communications in 22 Utah communities hinder efforts to connect those in need with food resources. The researchers identified four clusters of communities: Food Secure, Food Insecure, Information Deserts, and Information Uncertain.
Groundwater is a vital source of freshwater for crops and drinking water. A new computer model reveals that 20% of the world's sensitive coastal ecosystems are at risk due to groundwater flow carrying pollutants. Fresh groundwater can provide essential resources, but its high variability poses risks to local ecosystems.
A new study by West Virginia University researchers found that economic development incentives may contribute to the decline of middle-class jobs. The study examined the impact of tax breaks on employment trends in two cities, San Antonio and Birmingham, and found that incentivizing creative-class industries led to job losses in workin...
Researchers advocate for a public health approach to prevent and treat firearm violence, leveraging critical care providers and government funding. A solid evidence base is crucial for effective interventions.
