A radical new approach in synthetic chemistry
Scientists at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory helped measure how unpaired electrons in atoms at one end of a molecule can drive chemical reactivity on the molecule's opposite side. As described in a paper recently published in the Journal of the American Chemical Society, this work, in collaboration with Princeton University, shows how molecules containing...
Study uncovers how bacteria use ancient mechanisms to self-repair
A new study led by UNSW Sydney scientists unveils how nature's oldest wheel, found within bacteria, can fix itself when times get tough.
Tracking explosions with toughened-up tracers
What happens in an explosion? Where do the products of that explosion go following the blast? These questions are often difficult to solve. New rugged tracer particles, developed by Pacific Northwest National Laboratory (PNNL) researchers, can provide some answers.
New research improves the coolness factor for athletes
Weekend joggers, competitive athletes and people keeping fit in the gym can say goodbye to sweaty armpits and clingy damp garments after a tough workout.
Gully erosion prediction tools can lead to better land management
Soil erosion is a significant problem for agricultural production, impacting soil quality and causing pollutants to enter waterways. Among all stages of soil erosion, gully erosion is the most severe phase, where large channels are carved through the field. Once gullies develop, they are challenging to manage through tiling; they require a more comprehensive approach along the impacted area.
Low-cost sensor records the level of rivers
Researchers at the University of Bonn have developed a method that allows the water level of rivers to be monitored around the clock. The cost-effective sensor is for instance suitable for area-wide flood warning systems. The study has been published in the journal Water Resources Research.
Adapting to a hotter planet has never been more important, and progress edged forward at COP27
As the COP27 climate summit drew to a close over the weekend, it's important to acknowledge that progress was made on climate adaptation—even if more can be done.
Can we protect Earth from space weather?
In early September 1859, the Northern Lights could suddenly be seen as far south as the Caribbean. The cause was a geomagnetic solar storm—specifically a coronal mass ejection, now dubbed the Carrington Event, after the astronomer who recorded it.
NET locus regulates both flavor quality and nutrient metabolite accumulation in rice
Rice (Oryza sativa L.) is one of the most important crops worldwide, providing much of the calorific needs for half of the global population. Economic development and rising living standards have led to the demand for rice gradually shifting from satisfying the need to "be full" to satisfying the need to "eat well," and combining flavor with nutrition is essential for the latter. Much research has...
Scientists add 'invisible fiber' to foods for a healthier diet
Scientists have converted native starches such as wheat, corn and cassava to dietary fiber that can be added to food to make it healthier without changing its texture, color or taste.
