Researchers switch off gene to switch on ultraviolet in butterfly wings

przez admin
Researchers have identified a gene that determines whether ultraviolet iridescence shows up in the wings of butterflies. The team showed that removing the gene in butterflies whose wings lack UV coloration leads to bright patches of UV iridescence in their wings. According to the researchers, the gene plays a critical role in the evolutionary process by which species become distinct from one another.

Physicists detect a hybrid particle held together by uniquely intense 'glue’

przez admin
Physicists detected a hybrid particle that is a mashup of an electron and a phonon, 'glued’ together with an exceptionally strong bond. It may be possible to tune the two components in tandem, enabling scientists to apply voltage or light to a material to tune not just its electrical properties but also its magnetism.

Scientists uncover new information about cellular death process, previously thought to be irreversible

przez admin
Researchers report a new method for analyzing pyroptosis — the process of cell death that is usually caused by infections and results in excess inflammation in the body — and show that the process, long thought to be irreversible once initiated, can in fact be halted and controlled. The discovery means that scientists have a new way to study diseases that are related to malfunctioning cell death processes and infections that can be complicated by out-of-control inflammation.

Researchers discover fossil of new species of pangolin in Europe

przez admin
Deeper analysis of fossils from one of Eastern Europe’s most significant paleontological sites has led to the discovery of a new species of pangolin, previously thought to have existed in Europe during the early Pleistocene but not confirmed until now.
