A small team of researchers at Purdue University has found the strongest evidence yet of the existence of abelian anyons. They have written a paper describing experiments they conducted designed to reveal the existence of the quasiparticles and have uploaded it to the arXiv preprint server while they await peer review. …

Making the case for slingshotting past Venus on the way to Mars
A team of researchers from the Johns Hopkins University Applied Physics Laboratory, North Carolina State University and NASA, has proposed, via whitepaper, that NASA should direct its Mars-bound spacecraft to fly by Venus first. In their paper, uploaded to the arXiv preprint server, the researchers outline their arguments for an opposition mission, as opposed to a conjunction mission.

Study determines fundamental parameters of the chemically peculiar star HD 108662
Astronomers have carried out a spectroscopic analysis of the atmosphere of a magnetic chemically peculiar star designated HD 108662. The study, described in a paper published June 29 on the arXiv preprint server, resulted in determining fundamental parameters of this star.

CRISPR Gene Editing In Human Embryos Wreaks Chromosomal Mayhem
A suite of experiments that use the gene-editing tool CRISPR-Cas9 to modify human embryos have revealed how the process can make large, unwanted changes to the genome at or near the target site. Nature reports: The first preprint was posted online on June 5 by developmental biologist Kathy Niakan of the Francis Crick Institute in London and her colleagues. In that…
New Exotica Catalog will help guide search for ET

Team in Germany observes Pauli crystals for the first time
A team of researchers at Heidelberg University has succeeded in building an apparatus that allowed them to observe Pauli crystals for the first time. They have written a paper describing their efforts and have uploaded it to the arXiv preprint server. …
LinkedIn’s AI Generates Candidate Screening Questions From Job Postings
LinkedIn is using AI and machine learning to generate screening questions for active job postings. From a report: In a paper [PDF] published this week on the preprint server Arxiv.org, coauthors describe Job2Questions, a model deployed that helps recruiters quickly find applicants by reducing the need for manual screening. This isn’t just theoretical research — Job2Questions was briefly tested across millions…
Is Space-Time Quantized Or Analog?
“What are the implications if ‘space-time’ (as conceived of in the Einstein Theory of General Relativity) is quantized like all other aspects of matter and energy?” asks Slashdot reader sixoh1. Space.com reports of a new study that tried to find out: In order for the math of general relativity to work, this fabric of space-time has to be absolutely smooth at…
How coronavirus drifts through the air in microscopic droplets
Aerosols are the tiny particles of liquid and material that float around in our environment. When they come from an infected person, they may be a significant source of coronavirus transmission.
