An international team of paleontologists has found matching sets of Early Cretaceous dinosaur footprints on what are now two different continents.
Scientists use evolution to bioengineer new pathways to sustainable energy, pharmaceuticals
Using evolution as a guiding principle, researchers have successfully engineered bacteria-yeast hybrids to perform photosynthetic carbon assimilation, generate cellular energy and support yeast growth without traditional carbon feedstocks like glucose or glycerol. By engineering photosynthetic cyanobacteria to live symbiotically inside yeast cells, the bacteria-yeast hybrids can produce important hydrocarbons, paving...
Public trust in drinking water safety is low globally
A new study finds more than half of adults surveyed worldwide expect to be seriously harmed by their water within the next two years. The study sought to understand public perceptions of drinking water safety. Because perceptions shape attitudes and behaviors, distrust in water quality has a negative impact on...
Study finds salamanders are surprisingly abundant in northeastern forests
Two recent amphibian-focused studies shed light on the ecological importance of red-backed salamanders, while confirming that proactive measures would prevent costly impacts from a wildlife disease spreading across Europe that has not yet reached North America.
CRISPR-based genome editing in Nile grass rats
A team of researchers has discovered a set of methods that enabled the first successful CRISPR-based genome editing in Nile grass rats.
Study finds nearly half of U.S. counties have at least one ‘pharmacy desert’
Nearly half of counties in the United States have at least one 'pharmacy desert' where there is no retail pharmacy within 10 miles, according to a new study.
Bioengineers develop lotus leaf-inspired system to advance study of cancer cell clusters
Bioengineers have harnessed the lotus effect to develop a system for culturing cancer cell clusters that can shed light on hard-to-study tumor properties. The new zinc oxide-based culturing surface mimics the lotus leaf surface structure, providing a highly tunable platform for the high-throughput generation of three-dimensional nanoscale tumor models.
A leaky sink: Carbon emissions from forest soil will likely grow with rising temperatures
The soils of northern forests are key reservoirs that help keep the carbon dioxide that trees inhale and use for photosynthesis from making it back into the atmosphere.
Two epicenters led to Japan’s violent Noto earthquake on New Year’s Day
The 7.5- magnitude earthquake beneath Japan's Noto Peninsula on Jan. 1, 2024, occurred when a 'dual-initiation mechanism' applied enough energy from two different locations to break through a fault barrier -- an area that locks two sides of a fault in place and absorbs the energy of fault movement, slowing...
Scientists propose guidelines for solar geoengineering research
To guide future research into solar geoengineering, an international group of scientists is making specific recommendations for evaluating proposals in order to identify the most feasible and legitimate scenarios for stratospheric aerosol intervention.
