This past weekend, the seven-day average of U.S. deaths from COVID-19 broke that record twice, at 2,123 on Saturday and 2,171 yesterday, according to the COVID Tracking Project at The Atlantic. Yesterday, the seven-day averages for

Triple threat: The first observation of three massive gauge bosons produced in proton-proton collisions
The Standard Model, the most exhaustive existing theory outlining fundamental particle interactions, predicts the existence of what are known as triboson interactions. These interactions are processes in which three-gauge bosons are simultaneously produced from one Large Hadron Collider event.

Oligourea foldamers mimic peptides' alpha-helices and effectively bind to drug targets
Some useful drugs consist of peptides acting on their protein targets. To make them more efficient and stable, scientists have found a way to replace crucial segments of the peptides with ureido units. These oligoureas, which are composed of urea-based units, fold into a structure similar to that of peptides. Oligourea-based "fake" peptides enhance the options for rational drug design, concludes t

Carbon emission from star-forming clouds
The carbon atom can be easily ionized, more easily than hydrogen atoms for example. In star forming regions, where massive young stars emit ultraviolet light capable of ionizing atoms, all the neutral carbon nearby becomes ionized. The singly-ionized carbon atom (abbreviated CII) emits a strong line in the far infrared that is both very intense and consequently a reliable proxy for the ultraviolet

Voyager Probes Find New Electron-Accelerating Physics in Deep Space
Image Credit: NASA / JPL Tech NASA launched the Voyager probes more than 40 years ago, and the fact we're still talking about the impact of these spacecraft is a testament to how well-planned these missions were. Both Voyager 1 and 2 are outside the solar system now, but there's plenty to see out there in the interstellar medium (ISM). A newly published study from the University of Iowa says that

Risks of invasive and alien predator species for health and ecology
Increasingly, exotic animals and plants are being intentionally and unintentionally introduced into Europe from areas where they naturally occur. In Germany alone, more than one thousand invasive alien species (IAS) are registered. Invasive species cause significant changes to species communities and ecological systems and are considered one of the most important risks to biological diversity. Bec

Stunning discovery reveals bonefish dive 450 feet 'deep' into the abyss to spawn
Using active acoustic telemetry and sonar data, a study provides the first detailed documentation of a shallow water fish diving 450 feet deep to spawn. Prior research has shown that bonefish dive about 164 feet to spawn, but this new and unprecedented study reveals that they reached depths of 450 feet, and moved below 325 feet for two hours before spawning in a rush upward to 220 feet deep.
