Flowers like hibiscus use an invisible blueprint established very early in petal formation that dictates the size of their bullseyes -- a crucial pre-pattern that can significantly impact their ability to attract pollinating bees.
Urban heating and cooling to play substantial role in future energy demand under climate change
Existing global energy projections underestimate the impact of climate change on urban heating and cooling systems by roughly 50% by 2099 if greenhouse gas emissions remain high, researchers report. This disparity could profoundly affect critical sustainable energy planning for the future.
Technique to study how proteins bind to DNA is easily misused; New study offers solution
Spike-in normalization helps molecular biologists ensure the accuracy of their results, but the technique is easily misused. New study suggests new guidelines for use of this valuable technique.
Exceptional warm air intrusions and omnipresent aerosol layers in the stratosphere
Extremely clean air on the ground, warm air intrusions and sulphate aerosol at high altitudes -- a research project has gained new insights into clouds in Antarctica.
Plant-derived secondary organic aerosols can act as mediators of plant-plant interactions
A new study reveals that plant-derived secondary organic aerosols (SOAs) can act as mediators of plant-plant interactions. This research was conducted through the cooperation of chemical ecologists, plant ecophysiologists and atmospheric physicists.
CRISPR/Cas9 modifies euglena to create potential biofuel source
Through genome editing using CRISPR/Cas9, researchers stably create euglena mutants that can produce wax esters with improved cold flow, making the esters suitable as feedstock for biofuels.
Folded or cut, this lithium-sulfur battery keeps going
Most rechargeable batteries that power portable devices, such as toys, handheld vacuums and e-bikes, use lithium-ion technology. But these batteries can have short lifetimes and may catch fire when damaged. To address stability and safety issues, researchers have designed a lithium-sulfur (Li-S) battery that features an improved iron sulfide cathode....
Bacteria work together to thrive in difficult conditions
In a new study, researchers have determined through both statistical analysis and in experiments that soil pH is a driver of microbial community composition -- but that the need to address toxicity released during nitrogen cycling ultimately shapes the final microbial community.
Researchers Drill Down on Mine Waste Monitoring Using Drones and Sensors
University of Queensland researchers are developing new ways to monitor mine waste using drones and ground sensors to improve safety and land rehabilitation across mine sites.
U.S. Sweltered Through Its 4th-Hottest Summer on Record
A very warm August wrapped up an extremely hot summer across the U.S., with many cities breaking all-time heat records.
