Phys.org / Universal structure of exceptional points revealed in nonlinear light‑based systems

Exceptional points, or EPs for short, are among the phenomena of modern physics. These are special points or locations at which the properties of matter, space or time change. In a new theoretical study, researchers from ...

Phys.org / Molecular clock transitions tune out the noise in the hunt for new physics

Heavy polar molecules are some of the most sensitive tools physicists have for probing what lies beyond the Standard Model, the theory that describes the particles and forces we know about. But turning that sensitivity into ...

Phys.org / Materials surrounding a fusion reaction can dramatically increase how often it occurs

Fusion at high temperatures powers the sun and, if harnessed, could provide a potential source of energy here on Earth. But controlling fusion reactions has other benefits. The process also generates subatomic particles called ...

Phys.org / Yeast survives after all 300 known spliceosomal introns are removed

Spliceosomal introns are noncoding DNA sequences located between exons in many eukaryotic protein-coding genes. Most are removed post-transcriptionally by RNA splicing and do not encode proteins, but they have been implicated ...

Phys.org / Programmable platform enables on-demand design of plant immune receptors against crop pathogens

Crop production faces threats from plant pathogens. Traditional disease-resistance breeding relies heavily on natural plant resistance genes that encode immune receptors adapted to particular pathogens. However, rapidly evolving ...
