Scientists from the National University of Singapore (NUS) have shown that excitonic resonances and transitions between excitons can significantly increase the efficiency of generating entangled photon pairs. This could lead to the development of efficient ultrathin quantum light sources.

Aliens From the Fourth-Dimension May Be Invading Our World—And We Don’t Even Know It
Theoretically, it’s impossible for us to perceive a 4D creature. That is, unless it broke into our three-dimensional reality.
A Cave Discovered on the Moon Opens up New Opportunities for Settlement by Humans
These could be incredibly valuable to future astronauts hoping to settle on the moon, acting as a convenient shelter for a lunar base.
The cave is accessible through a pit in the well-studied Mare Tranquillitatis (Sea of Tranquility). This is a large basin made mostly of basalt. Neil Armstrong and Buzz Aldrin touched down in this region on July 20 1969.
While Mare Tranquillitatis isn’t likely to be the first place humans try to settle on the moon, the existence of one cave makes the existence of others very likely, so scientists now expect there to be others in locations more suitable for human settlement.
Geophysicists find link between seismic waves called PKP precursors and strange anomalies in Earth’s mantle
For the decades since their discovery, seismic signals known as PKP precursors have challenged scientists. Regions of Earth’s lower mantle scatter incoming seismic waves, which return to the surface as PKP waves at differing speeds.
13,600-year-old remarkably intact mastodon skull discovered in Iowa
In an unexpected turn of events, a two-week archaeological dig unearthed a remarkably intact mastodon skull in a creek that might carry signs of human life too.
Over twelve days, archaeologists unearthed several mastodon bones. However, the skull, being “the first-ever well-preserved” artifact of its kind, makes it a significant find with potential connections to human history.
“We’re really hoping to find evidence of human interaction with this creature — perhaps the projectile points and knives that were used to kill the animal and do initial butchering,” John Doershuk, director and state archaeologist at the University of Iowa Office of the State Archaeologist (OSA) said.

Blind cavefish have extraordinary taste buds
UC biologist Joshua Gross studies blind cavefish, a species of fish that dwell in cave ponds in Mexico. In a study, supported by the National Science Foundation, Gross looked at the timeline for when the cavefish develop additional taste buds on the head and chin, finding the taste bud expansion starts at five months and continues into adulthood.
