How plants compete for light: Researchers discover new mechanism in shade avoidance
Plants that are close together do everything they can to intercept light. This "shade avoidance" response has been extensively researched. It is therefore even more remarkable that researchers from the laboratory of Molecular Biology at Wageningen Un.....»»
Microbes in environment drove methane emissions more than fossil fuels between 2020 and 2022, analysis finds
Microbes in the environment, not fossil fuels, have been driving the recent surge in methane emissions globally, according to a new, detailed analysis published Oct 28 in the Proceedings of the National Academy of Sciences by CU Boulder researchers a.....»»
Loss of "nitrogen fixers" threatens biodiversity, ecosystems, say biologists
Mississippi State University is part of a European-American collaboration studying how human activities, like fertilizer use and pollution, are impacting nitrogen-fixing plants which are crucial for maintaining healthy ecosystems by adding nitrogen t.....»»
Invasive flathead catfish impacting Susquehanna"s food chain, researchers find
Flathead catfish—native to the Mississippi River basin—were first detected in the Susquehanna River in Pennsylvania in 2002, according to the U.S. Geological Survey. In the two decades since then, the invasive species has spread throughout the ri.....»»
Fungi finding: mushroom hunters seek new species and recognition
You can't walk very far through a forest in this part of the United States without stumbling upon a mushroom, an eruption from a vast fungal kingdom that all life depends on, but about which we know very little......»»
Male stalk-eyed flies with short eyestalks are less attractive to females but fight more fiercely, scientists discover
In stalk-eyed flies, longer eyestalks attract the ladies. Females prefer males with longer eyestalks, and other males are less likely to fight them for access to females. But some males have a copy of the X chromosome which always causes short eyesta.....»»
Dolphins Are Exhaling Microplastics
New research highlights how extensive plastic pollution is—and how nonhuman species, including dolphins, are exposed......»»
Bizarre fish has sensory “legs” it uses for walking and tasting
Some sea robin species can use their legs to sense prey. Evolution has turned out bizarre and baffling creatures, such as walking fish. It only gets weirder from there. Some of th.....»»

Q&A: Experts discuss the beaver, a controversial mammal
When an endangered species succeeds in repopulating its former habitat, the immediate reaction is one of joy. In the long term, however, its spread is often associated with conflict. One example is the beaver, a keystone species. Other keystone speci.....»»

Bumblebee queens choose to hibernate in pesticide-contaminated soil, scientists discover
An alarming discovery from University of Guelph researchers raises concerns for bumblebee health, survival and reproduction. U of G environmental sciences researchers Drs. Nigel Raine and Sabrina Rondeau have found that bumblebee queens are more like.....»»
Better ocean connectivity boosts reef fish populations, finds study
Research led by the University of Oxford has found that oceanographic connectivity (the movement and exchange of water between different parts of the ocean) is a key influence for fish abundance across the Western Indian Ocean (WIO). The findings are.....»»
Resolving biology"s dark matter: DNA barcoding reveals hidden insect diversity
There are millions of species on Earth that we still know nothing about. Researchers call these species "biological dark matter," but new methods can provide us with a better overview more quickly......»»
MAX phases boost electrocatalytic biomass upgrading
Biomass is among the most abundant renewable resources on Earth. Through catalytic conversion, biomass can upgrade into a series of fuels and chemicals which can substitute traditional fossil resources, thus playing a crucial role in achieving the "c.....»»
Biofilms study reveals how multiple bacteria species manage to coexist
Biofilms—slimy communities of bacteria—grow on all sorts of surfaces: from glaciers and hot springs to plant roots, your bathtub and fridge, wounds, and medical devices such as catheters. Most biofilms are composed of multiple bacterial species,.....»»
DNA-binding C2H2 zinc finger proteins also regulate RNA processing, researchers discover
Researchers at the University of Toronto have shown that an important class of DNA-binding factors can also bind to RNA, regulating gene expression through various mechanisms. The study significantly expands our understanding of these proteins' funct.....»»
Stem carbohydrate richness in two cycad species
Terrestrial plants have developed strategies to cope with suboptimal conditions. Storage of nonstructural resources is one of those strategies. Nonstructural carbohydrates (NSCs) of plants are primarily sugars and starch, and have been studied extens.....»»
