Phys.org / Bacteria's hidden Achilles' heel: Sugar-phosphate buildup disrupts cell wall synthesis
Antibiotic resistance is considered one of the most urgent health threats of our time. Common bacteria such as E. coli and Staphylococcus aureus are evolving defenses against the drugs doctors rely on most. To combat the ...
Phys.org / Forever chemicals are more acidic than we thought, study finds
One of the ways that per- and polyfluoroalkyl substances (PFAS) earn their "forever chemical" nickname and persist in the environment is their acidity.
Phys.org / Iron-laden fluids drive abiotic organic synthesis in dolomitic marble, offering insight into origin of early life
Abiotic organic synthesis during geological processes has long drawn scientific interest, as it is believed to have laid both the material and energetic groundwork for the emergence of early life on Earth.
Phys.org / How extreme temperatures alter reptile reproduction
Biodiversity is disappearing at an alarming rate and is driven by human activity: contamination, greenhouse gases and extreme temperatures. But how exactly do these factors affect the reproduction and survival of species?
Phys.org / Current extinction rates haven't reached level of 'mass extinction' just yet, study suggests
Hundreds of species have gone extinct in recent centuries, but losses are few among larger classification levels, meaning we are not witnessing a mass extinction just yet, according to a study published in the open-access ...
Phys.org / Magnetic nanoparticles in synthetic cells enable controlled, deep-tissue drug release with reduced side effects
A synthetic cell that can be activated by a magnetic field to release a medicine while deep in the body has been created by chemists at UCL (University College London) and the University of Oxford.
Phys.org / Milk ingredient helps produce a new bioplastic—and more can be done
With rising risk to the environment and human health, the race for biodegradable plastics is gaining pace—with several projects under way at Flinders University in South Australia.
Phys.org / Broccoli seeds can spread resistance to multiple fungicides
A new study found evidence that commercial broccoli seeds can harbor a fungal seedborne pathogen, Alternaria brassicicola, with cross resistance to two commonly used fungicides.
Phys.org / Giving food waste fermentation a 'jolt' increases chemical production
Adding an electrical jolt to fermentation of industrial food waste speeds up the process and increases the yield of platform chemicals that are valuable components in a wide range of products, new research shows.
Phys.org / Observation-informed deep learning cuts ENSO projection uncertainty
El Niño-Southern Oscillation (ENSO) is the strongest interannual variability signal in Earth's climate system. The shifts between its warm and cold phases profoundly impact global extreme weather, ecosystems, and economic ...
Phys.org / Ancient plant protein offers new path for broad-spectrum pathogen resistance in crops
Researchers led by Ken Shirasu at the RIKEN Center for Sustainable Resource Science (CSRS) in Japan have identified an ancient protein that has the potential to help defend plants against tens of thousands of different bacteria ...
Phys.org / Open-source computational tool sheds light on 'wiggly' proteins
Most well-studied proteins are folded, meaning they have a defined three-dimensional shape that helps determine each protein's specific function. But as the tools of science have improved, so has the understanding that many ...
