Striking lane-like patterns found in bacteria populations
It's well understood that populations of species don't distribute at random. Rather, as populations grow, individuals are organized around barriers in the landscape. This organization can be seen in, for example, the growth of the cells around the ou.....»»
Diversity in typhoid bacteria linked to higher mortality rates
Worldwide, 20% of the bacterial strains that cause typhoid fever have genetic variations in their external layer, called Vi capsule, that provide higher virulence, higher infectivity and high antibiotic resistance, Cornell researchers have discovered.....»»
High elevation regions may become wildlife refuges through climate change
As climate change advances, its impacts are not universally equal, with temperature rising differently by latitude and elevation. Climate heterogeneity is the study of this diversity in Earth's climate patterns, and the focus of recent research publi.....»»
Intracellular mechanisms shown to promote spread of deadly bacterial infection
Northwestern Medicine investigators have discovered novel protein mechanisms that promote the rapid spread of Vibrio vulnificus, a rare but lethal bacteria that can cause vibriosis and sepsis, according to findings published in the Proceedings of the.....»»
New microbe-central model predicts global grassland soil pH under climate change
In a study published in One Earth on July 5, a research team led by Prof. Deng Ye from the Research Center for Eco-Environmental Sciences of the Chinese Academy of Sciences proposed the core-bacteria-forecast model (CoBacFM), which links the changes.....»»
Study reveals how stress pathways activate a cell"s emergency response procedures
Mayday! SOS! Distress signals like these are used around the world to indicate an emergency. The cells that make up your body also have their own versions of emergency signals. These get activated if a cell is infected by a virus or bacteria, or if t.....»»
How to ensure higher-density housing developments still have enough space for residents" recreation needs
Growing populations and housing shortages are affecting cities worldwide, including in Australia. It's driving them to adopt high-density development near public transport hubs instead of endless suburban sprawl on city fringes......»»
Getting bacteria into line: Physicists use magnetic fields to manipulate bacterial behavior
Researchers at Finland's Aalto University have found a way to use magnets to line up bacteria as they swim. The approach offers more than just a way to nudge bacteria into order—it also provides a useful tool for a wide range of research, such as w.....»»
Study reveals rapid evolution and global spread of Pseudomonas aeruginosa
Pseudomonas aeruginosa—an environmental bacteria that can cause devastating multidrug-resistant infections, particularly in people with underlying lung conditions—evolved rapidly and then spread globally over the last 200 years, probably driven b.....»»

Study reveals ancient Nile floods were highly variable during wetter climates
Global warming as well as recent droughts and floods threaten large populations along the Nile Valley. Understanding how such a large river will respond to an invigorated hydrological cycle is therefore a pressing issue. Insights can be gained by stu.....»»
It"s a challenging drive to Washington"s ocean beaches as state spends billions to help fish
It took 50 million years for salmon to evolve and only about 50 years to nearly wipe them out. Now, Washington's native salmon and steelhead populations are getting a reprieve—one stream at a time......»»
Experts warn of sewage, E. coli in Missouri River: Flooding could make quality worse
The Kansas Department of Health and Environment advised residents last week to stay out of the Missouri River due to contamination from raw sewage and E. coli bacteria. Five days later, the river is still dangerous to enter—both due to high water l.....»»
How many giraffe species are there? Understanding this maybe key to their protection
Giraffes, with their distinctive body shape and variations in coat patterns, have long been an example in evolutionary biology teachings. They are a textbook example of how species adapt to their surroundings and survive under harsh conditions. Despi.....»»
Nitrogen-using bacteria can cut farms’ greenhouse gas emissions
Nitrogen fertilizers get converted to nitrous oxide, a potent greenhouse gas. Enlarge (credit: Timothy Hearsum) Fritz Haber: good guy or bad guy? He won the Nobel Prize in Chemistry in 1918 for his part in developing the.....»»
Unveiling sea country management monitoring trends in Australia
AIMS scientists have partnered with Indigenous communities in the remote Kimberley region of Australia's northwest to monitor culturally important fish populations on coral reefs and incorporate the variability in data to better inform sea country ma.....»»
Unexpected source of nutrients fuels growth of toxic algae from Lake Erie
Climate change, such as warming and changes in precipitation patterns, affects the frequency and severity of harmful algal blooms (HABs) globally, including those of toxin-producing cyanobacteria that can contaminate drinking water......»»
Q&A: How to make sustainable products faster with artificial intelligence and automation
By modifying the genomes of plants and microorganisms, synthetic biologists can design biological systems that meet a specification, such as producing valuable chemical compounds, making bacteria sensitive to light, or programming bacterial cells to.....»»
The missing puzzle piece: A striking new snake species from the Arabian Peninsula
Researchers have discovered a new distinctive and secretive snake species in the Hejaz region of Saudi Arabia......»»
New method could significantly reduce agricultural greenhouse gas emissions
New research by the Norwegian University of Life Sciences (NMBU) and International Institute for Applied Systems Analysis (IIASA) proposes using soil bacteria to cut greenhouse gas emissions from food production. The research is published in the jour.....»»
