Two new rotating radio transients discovered by astronomers
The time in milliseconds is delayed along the horizontal axis. The vertical axis shows the frequency of observations in MHz. The dark line within the dynamic spectrum is the signal of the detected transient. The intensity of radiation within the dynamic spectrum is shown in shades of gray. The darker the color, the stronger the …

Researchers argue that human longevity is partly due to the contributions of the elderly
Credit: CC0 Public Domain According to a long-standing canon in evolutionary biology, natural selection is cruelly selfish, promoting traits that promote reproductive success. This usually means that the so-called “power” of selection is well equipped to remove deleterious mutations that occur during early life and throughout the reproductive years. But by the age that fertility …

New molecular bond discovered by physicists is longer than some bacteria
The special ion microscope used in the discovery. Image credit: Nicolas Zuber For the first time, physicists have observed a molecular bond between a positive ion and a Rydberg atom, which is a special excited state in which electrons occupy orbitals much further from the nucleus than normal. A Rydberg atom can be 1000 times …

Credit: Coder Lab/CCNY City College of New York, associate professor of physics Ronald Koder and his team at the Koder Lab are advancing the field of molecular sensing by developing the first proteins that can detect a lethal nerve agent called VX in real time …
CERN July 5 myths about particle accelerators debunked
CERN’s July 5 particle accelerator did not create a cosmic black hole. The machine also cannot shift time and space, as viral conspiracy theories claim. On July 5, 2022, the European Organization for Nuclear Research, known as CERN, restarted its machine known as a particle accelerator. The machine rebooted today after a three year hiatus …

Researchers advance understanding of vortex diffusion in superfluidics
An illustration of a vortex tangle. Credit: Wei Guo/FAMU-FSU College of Engineering An international team of scientists with researchers from Florida State University has developed a model that predicts the distribution of vortices in so-called superfluidics, work that provides new insight into the physics that controls turbulence in quantum fluid systems such as superfluid neutron …

Why isn’t the inside of the solar system spinning faster? Old mystery may have new solution
Credit: Shutterstock According to a new study from Caltech, the movement of a small number of charged particles may solve a long-standing mystery about thin disks of gas orbiting young stars. These functions, called accretion disks, last for tens of millions of years and represent an early stage in the evolution of the solar system. …
