Phys.org / Revealing the cell's nanocourier at work
An international group of researchers led by Pompeu Fabra University has discovered the nanomachine that controls constitutive exocytosis: the uninterrupted delivery of spherical molecular packages to the cell surface. This ...
Phys.org / Biomass-derived furans offer sustainable alternative to petroleum in chemical production
A research project conducted by the Max-Planck-Institut für Kohlenforschung shows how biomass can be used as a raw material for chemical products instead of petroleum. The scientists have published their findings in the ...
Phys.org / Nationwide racial bias shapes media reporting on gun violence, study suggests
Mass shootings in white-majority neighborhoods received roughly twice the news coverage of mass shootings in neighborhoods where a majority of residents were people of color, while coverage of police-involved shootings was ...
Phys.org / How actin wavefronts rescue T cell receptors from endocytosis
Every time our body encounters a new disease-causing agent, a crucial defense system called adaptive immunity comes into play. T cells, the top agents in this system, survey the internal environment of infected cells and ...
Phys.org / Sideways discovery rewrites the rules of antigen presentation
A new discovery about how cells communicate with each other in the body's immune system has revealed deeper insights for an international team of scientists into fundamental immune system function.
Phys.org / When tropical oceans were oxygen oases
Research reveals when and why ancient tropical seas transitioned from oxygen oases to marine dead zones, providing clues to the long-term evolution of oceanic environments.
Phys.org / Plant diversity shapes chemical communication in ecosystems
Researchers at the Max Planck Institute for Chemical Ecology and the University of Kiel have provided experimental evidence showing that reducing plant species diversity alters plant chemical signals across whole communities ...
Phys.org / Cells use dual strategies to fine-tune inflammatory gene activation
Inflammation has to fight pathogens fast—but it can't get out of control. Researchers at the German Cancer Research Center (DKFZ) have now deciphered in more detail how the organism masters this balancing act. Their work ...
Phys.org / Exploring mutations that spontaneously switch on a key brain cell receptor
Many people are familiar with histamine, a biological molecule that serves as a key driver of allergic reactions and other immune responses. However, histamine is also a major neurotransmitter in the mammalian brain, regulating ...
Phys.org / Ancient Type II supernova discovered from universe's first billion years
Using the James Webb Space Telescope (JWST), an international team of astronomers has discovered a new Type II supernova. The newly detected supernova, named SN Eos, exploded when the universe was only 1 billion years old. ...
Phys.org / Antarctic submillimeter telescope enables more complete view of the carbon cycle in star-forming regions
Chinese researchers have braved the cold and harsh environment of Antarctica in order to get a unique view of star formation in the interstellar medium (ISM). The Chinese National Antarctica and Arctic Research Expedition ...
Phys.org / Temporal anti-parity–time symmetry offers new way to steer energy through systems
The movement of waves, patterns that carry sound, light or heat, through materials has been widely studied by physicists, as it has implications for the development of numerous modern technologies. In several materials, the ...
