Phys.org / For certain life-essential proteins in E. coli, repair is more likely
Proteins need to fold into specific shapes to perform their functions in cells, but they occasionally misfold, which can prevent them from properly functioning and even lead to disease.
Phys.org / How natural disasters exacerbate inequity
An AI analysis of Google Street View images across 16 states shows that damaged buildings in poorer communities often remain vacant for years, while wealthier areas rebuild faster and better.
Phys.org / Opposing forces in cells could hold clues to treating disease
A newly revealed molecular tug-of-war may have implications for better understanding how a multitude of diseases and disorders—including cancers, neurodegenerative diseases and immune disorders—originate, as well as how ...
Phys.org / Uncovering early embryonic communications using new stem cell model
From the moment an embryo starts to take shape, two-way communication is critical for making sure tissues and organs develop correctly.
Phys.org / Remote Southern Ocean seabirds study highlights reach of 'forever chemicals'
Seabirds in one of the remotest parts of the planet are being exposed to a wide range of forever chemicals, scientists have discovered.
Phys.org / Composite copper oxides show strong, long-lasting antiviral action against tough viruses
Composite copper–lanthanum and copper–yttrium oxides developed by researchers from Japan demonstrate exceptionally high antiviral activity against non-enveloped virus. These oxides are highly stable and achieve more than ...
Phys.org / After devastating wildfires, watersheds are surprisingly thick with fish and amphibians
In the aftermath of historically severe wildfires in 2020, a study of Cascade Range watersheds found that stream vertebrates are doing surprisingly well, highlighted by flourishing fish populations.
Phys.org / Firefighter gear contains potentially hazardous flame retardants, study shows
Some firefighter gear is manufactured with chemicals called brominated flame retardants that could pose a risk to firefighter health, according to a study published in Environmental Science & Technology Letters.
Phys.org / Surface-engineered ZnO nanocrystals tackle perfluoroalkyl substance contamination
Perfluoroalkyl substances (PFASs), a large class of synthetic chemicals, are valued for their ability to withstand heat, water, and oil. These materials are used in the production of everyday as well as industrial items. ...
Phys.org / ROSE-3D advances isotropic 3D super-resolution microscopy
In a study published in Nature Methods on December 2, a research team led by Profs. Xu Tao and Ji Wei from the Institute of Biophysics of the Chinese Academy of Sciences has developed a three-dimensional interferometric localization ...
Phys.org / Cool satellites and flexible electronics: Thin interlayers strengthen flexible composite materials
The picture that pops up before our inner eye when we hear the word "satellite" is probably this: Two extended solar "wings" and a compact body wrapped in foil with a golden or silvery shimmer. Researchers at Empa's Mechanics ...
Phys.org / How cells survive oxidative stress and ferroptosis
EPFL scientists have identified a molecular pathway that protects cells from lipid oxidation and ferroptosis, a regulated form of cell death involved in aging and several diseases.
