Phys.org / How bacteria use acetyl coenzyme as a building block in the formation of cells
Researchers at the University of Greifswald have discovered a new mechanism by which bacteria such as Bacillus subtilis can regulate the production of the central metabolic molecule acetyl coenzyme A (Acetyl-CoA). Acetyl-CoA, ...
Phys.org / Why shame is an evolution-based defense mechanism
It is unpleasant, strange and often comes as a surprise: shame. But why do we feel it? An international study has shed new light on the emotion of shame, which has long been considered harmful. The conclusion: Shame is not ...
Phys.org / Even weak ocean models can provide valuable information for environmental forecasts, study shows
Oxygen depletion in the western Baltic Sea is not uncommon. Oxygen-poor conditions regularly occur in deeper waters, placing stress on marine ecosystems and, in extreme cases, causing fish kills. As ocean temperatures continue ...
Phys.org / Salmonella genomes reveal 45 previously unknown toxins in foodborne bacteria
Researchers at the University of São Paulo (USP) in Brazil have discovered 45 new toxins produced by Salmonella bacteria, some of which are associated with foodborne infections. The study was conducted at the Center for Research ...
Phys.org / Ocean glow meets 3D printing with living gels that sense mechanical force
The integration of biological organisms into synthetic structures offers a radical new pathway for developing intelligent, self-powered materials. Researchers have pioneered an innovative approach to biomanufacturing by using ...
Phys.org / Cyclone Gabrielle-style storms may unleash tens of thousands more North Island landslides
In 2023, Cyclone Gabrielle triggered an estimated 800,000 landslides across the North Island, making it one of the most extreme landslide events ever recorded. New research by Te Whare Wānanga o Waitaha | University of Canterbury ...
Phys.org / Why animal calls sound alike in time: Most species share a common communication tempo
From insects to great apes, by way of birds and fish, animals communicate through an extraordinary variety of sounds. While the pitch or timbre of their vocalizations matters, rhythm may play a more fundamental role. Scientists ...
Phys.org / New art test could help museums spot fake Van Goghs without touching paintings
A new study published in the peer-reviewed journal Surface Topography: Metrology and Properties introduces a pioneering, noninvasive technique that can distinguish authentic artworks from forgeries, offering museums, collectors, ...
Phys.org / Would you return a favor? Scientists say it depends on the relationship
When a friend buys you a cup of coffee, it's likely that next time, you'll return the gesture. This type of reciprocal generosity has been well-documented in behavioral economics studies. However, anthropologists and other ...
Phys.org / Novel nanowire device offers rapid, noninvasive cancer detection
A research team in Japan has developed an efficient, minimally invasive cancer detection device that uses high-performance zinc oxide nanowires to selectively capture extracellular vesicles (EVs) from bodily fluids.
Phys.org / 'Janus-faced' nanomaterials pave the way for selectively capturing radioactive pollutants
A KAIST research team has succeeded, for the first time, in synthesizing the core raw material for fabricating asymmetric MXene, a so-called "Janus-faced" nanomaterial that can perform distinct functions because of differing ...
Phys.org / Cosmic acceleration holds up as new analysis rebuts slowdown claim
Our universe's expansion is still accelerating despite recent claims suggesting otherwise, an international team of astrophysicists says.
