Propagating dimensions of light: Deforming versatile non-diffractive beams along the optical trajectory

The diffraction of light is a ubiquitous phenomenon in nature where waves spread out as they propagate. This spreading of light beams during propagation limits the efficient transmission of energy and information. Therefore, ...

Marine microplastics: How water mass dispersal impacts transport trajectories

Marine microplastics (1 μm–5 mm diameter) are an ever-pressing concern, given their longevity in the environment (>100 years) and the effects they have on the organisms inhabiting them, particularly as ocean currents carry ...

Passing stars altered orbital evolution of Earth and other planets, astronomers find

Stars that pass by our solar system have altered the long-term orbital evolution of planets, including Earth, and, by extension, modified our climate.

A new virus-like entity has just been discovered—'obelisks' explained

Biological entities called obelisks have been hiding—in large numbers—inside the human mouth and gut. These microscopic entities, which were recently discovered by a team at Stanford University, are circular bits of genetic ...

Engineers uncover new mechanism for gene transfer

If you still remember that "Dear King Phillip Came Over For Good Spaghetti," you'll likely also recall the corresponding taxonomic ranks of biology: domain, kingdom, phylum, class, order, family, genus and species. The domains ...

Study shows how hurricane acted as a highway to transport microplastics to remote part of Newfoundland

When a hurricane approaches and crosses land, severe damage can occur—often leaving an obvious trail of physical destruction. What's less obvious to the naked eye is how these storms can carry harmful microplastics across ...

What would happen to Earth if a rogue star came too close?

Stars are gravitationally fastened to their galaxies and move in concert with their surroundings. But sometimes, something breaks the bond. If a star gets too close to a supermassive black hole, for example, the black hole ...
