How symbiotic bacteria adapt to big environmental changes
Studying the impact of the environment on animal evolution is no easy task, as most animals reproduce slowly and exhibit complex behaviors. However, microbiologists have an advantage: Bacteria reproduce rapidly, which makes them a much easier subject.....»»
Battling anthracnose: Unearthing the plant"s arsenal against pathogenic fungi
Plant diseases caused by pathogens like Colletotrichum fructicola lead to significant agricultural losses, particularly in fruit crops such as pear, apple, and peach. Traditional control methods often fail as pathogens adapt to plant defenses. Nonhos.....»»
Global South health care practices contribute to spread of antimicrobial resistance across the world, study suggests
Many bacteria resistant to multiple antibiotics originate in Pakistan and other parts of the Indian subcontinent. Infections caused by these bacteria are challenging to treat; longer treatment with broad-spectrum antibiotics is required and despite t.....»»
Heat and disease: The genetic tug-of-war in pepper immunity
Plants face simultaneous challenges from pathogens and environmental stresses, especially in tropical and subtropical regions. Pathogens trigger immune responses through specific receptors, while high temperatures activate heat tolerance mechanisms......»»
Squeezing more flavor: Genetic study optimizes citric acid in tomatoes
Citric acid (CA) is a flavor-enhancing compound in tomatoes that also serves as a metabolic pathway mediator. Despite its importance, the genetic and environmental interplay affecting its levels has been a puzzle, difficult to decipher and control......»»

Human activity: A double-edged sword in the face of drought
Earth and environmental scientists have reported that, as human socio-economic activities increase, greenhouse gas emissions will rise, leading to more frequent extreme weather events such as droughts and floods. However, a research team from Pohang.....»»
Many more bacteria produce greenhouse gases than previously thought, study finds
Caltech researchers have discovered a new class of enzymes that enable a myriad of bacteria to "breathe" nitrate when in low-oxygen conditions. While this is an evolutionary advantage for bacterial survival, the process produces the greenhouse gas ni.....»»
New insights into how cell shape influences protein transport rates
When a cell spreads out or changes its shape to adapt to its environment, the transport rate of proteins between the nucleus and cytoplasm changes. Previously, scientists assumed this change was caused by a shift in the size of the nuclear envelope's.....»»
Interactive map shows future climate of your city based on emissions scenarios
The impacts of climate change are being felt all over the world, but how will it impact how your hometown feels? An interactive web application from the University of Maryland Center for Environmental Science allows users to search 40,581 places and.....»»
Citizen scientists gather eDNA in water samples for global biodiversity census
Kara Andres, a postdoctoral fellow with the Living Earth Collaborative at Washington University in St. Louis, collected samples of water from Simpson Lake, in Valley Park, Mo., as part of a coordinated global effort to use environmental DNA—genetic.....»»
What actually makes avocados bad for the environment?
The soaring demand for avocados in Europe and North America has led to a trebling of global production in just over 20 years. However, this popular fruit is increasingly controversial because of the environmental impacts of farming and distributing t.....»»
Hidden partners: Symbiodolus bacteria found in various insect orders
Scientists at the Max Planck Institute for Chemical Ecology report the discovery of at least six orders of endosymbiont Symbiodolus clandestinus, which lives inside insect cells. Using fluorescence in situ hybridization, they showed that Symbiodolus.....»»
