Phys.org / 'Canary in the coal mine': Superb fairy-wrens in Canberra could go extinct within 30 years
Superb fairy-wrens are facing "imminent danger," and a well-studied population in Canberra could go extinct in the next 30 years if we don't urgently curb greenhouse gas emissions, according to an international team of scientists ...
Phys.org / Millions-of-years-old insect symbioses are surprisingly fragile
Many insects have lived in close symbiosis with bacteria for millions of years, during which time the bacteria have provided them with vital nutrients, making the mutualistic relationship so close that neither partner can ...
Phys.org / Are relationship surveys measuring the wrong thing? How one 'Q-factor' shapes most answers
Commonly used self-report measures of romantic relationships may capture people's overall appraisal of their relationship more than measuring distinct relationship facets such as communication, conflict and affection, according ...
Phys.org / How plants fight back against bacteria that promote waterlogging in leaves
Farmers, gardeners, and botanists have long observed that plant diseases tend to flare up during periods of high humidity, particularly after rainfall. Humid conditions help bacteria enter plant leaves, and once inside, certain ...
Phys.org / Vegetation patterns and ecosystem resilience: Why their relationship status is 'complicated'
In dryland ecosystems, increased environmental stress often triggers a change from a uniform vegetation cover to patchy vegetation patterns. Some theoretical studies suggest that this spatial self-organization of vegetation ...
Phys.org / Air surveillance reveals hidden reservoirs of antibiotic resistance genes
A review finds that antibiotic resistance genes—capable of undermining modern medicine—can travel through the air across both cities and farmland, and argues that airborne spread represents an overlooked public health risk.
Phys.org / Terraforming Mars: Modeling engineered aerosols to warm the planet
Whenever humans arrive on Mars, they're going to find it a difficult place to exist. Mars is cold, with an average surface temperature of -55°C; temperatures can plunge to -125°C with dust storms lasting months; its atmosphere ...
Phys.org / New index reveals global water resources' growing dependence on extreme rainfall
As global temperatures climb, rainfall patterns are shifting in ways that could put water resources and agriculture under increasing strain, a new study published in Water Resources Research suggests.
Phys.org / Lost mosaic reveals first image of female beast-fighter from the Roman era
When you think of a fight between an animal and a human in ancient Roman sports, the mental image is usually of a big man vs. an animal in a big arena filled with cheering spectators. In a new study, Alfonso Manas, a researcher ...
Phys.org / Astronomers determine the fate of a double white dwarf binary
Utilizing the stellar evolution code named Modules for Experiments in Stellar Astrophysics (MESA), Chinese astronomers have investigated the evolution of a recently discovered ultra-compact double white dwarf binary system ...
Phys.org / SimCells successfully target and kill drug-resistant bacteria
We are continually in an evolutionary arms race with bacteria. As we develop new antibiotics, they develop resistance, and so it goes on until some of our treatments no longer work. Superbugs and antimicrobial resistance ...
Phys.org / Gaia analysis finds Messier 35 is larger and older than earlier estimates
Astronomers from Egypt and Turkey have conducted a comprehensive analysis of kinematic, structural, and astrophysical parameters of a nearby open cluster known as NGC 2168. Results of the new study, published March 23 on ...
