Conventional plant regeneration approaches by cell culture require the external application of plant growth regulators, including hormones. However, optimizing culture conditions can be laborious. Now, researchers have developed a novel plant regeneration system that omits the need for hormone application by genetically regulating the expression of genes that control plant...

Activity in a room stirs up nanoparticles left over from consumer sprays
Common household products containing nanoparticles -- grains of engineered material so miniscule they are invisible to the eye -- could be contributing to a new form of indoor air pollution, according to a new study.
Astronomers share climate-friendly meeting solutions
Carbon emissions associated with air travel to professional conferences make up a sizable fraction of the emissions produced by researchers in academia.
Scientists show ancient village adapted to drought, rising seas
Researchers have unveiled evidence for ancient human resilience to climate change in the Eastern Mediterranean.
Methane emissions from landfill could be turned into sustainable jet fuel in plasma chemistry leap
Researchers have developed a chemical process using plasma that could create sustainable jet fuel from methane gas emitted from landfills, potentially creating a low-carbon aviation industry.
Big data reveals true climate impact of worldwide air travel
A new study that looked at nearly 40 million flights in 2019 calculated the greenhouse gas emissions from air travel for essentially every country on the planet. At 911 million tons, the total emissions from aviation are 50 per cent higher than the 604 million tons reported to the United...
New and improved way to grow the cells that give rise to the kidney’s filtration system
Scientists report significant progress in cultivating nephron progenitor cells (NPCs), the cells destined to form the kidney's filtration system, the nephrons. NPCs hold immense promise for understanding kidney development, modeling diseases, and discovering new treatments. The team improved the chemical cocktail for generating and growing NPCs in the laboratory, enabling...
Researchers parse oddity of distantly related bats in Solomon Islands that appear identical
A study of body size in leaf-nosed bats of the Solomon Islands has revealed surprising genetic diversity among nearly indistinguishable species on different islands.
Long Snouts Protect Foxes When ‘Mousing’ Headfirst in Snow
When hunting for mice in winter, red and Arctic fox are known to plunge headfirst at speeds of 2-4 meters per second but their sharp noses reduce the impact force in snow and protect them from injury, according to a new study published April 29 in the Proceedings of the...
How Can Forests Be Reforested in a Climate-Friendly Way?
Only a few tree species are flexible enough to survive a century of rapid climate change.
