Chemists have created a new way to make fluorescent solids, paving the way to create materials in a wider array of colors and for use in many more applications. The process, described in Chem, mixes cyanostar molecules with the dyes, which keeps the dye molecules farther apart so they can retain their fluorescent properties while in a solid state.

Some of the heat generated to keep oceans wet on Jupiter's moons may be produced by the moons working together gravitationally, according to findings published in Geophysical Research Letters. Researchers say the moon neighbors may create tidal waves on each other's surfaces to produce resonance and generate heat due to friction.

A study in Psychological Bulletin has found that youths who experienced threat-related trauma such as abuse or violence were more likely to show signs of accelerated aging on a cellular level and are more likely to enter puberty early compared with those who did not experience these traumas. However, the findings, based on a review of 54 studies assessing links of early-life adversity to pubertal timing and cellular aging and 25 studies evaluating early-life adversity and neural markers of accelerated development, showed that youths who experienced neglect or poverty did not exhibit either of the early-aging signs.

Dairy cows form bonds by grooming, study finds
(Pixabay)
Social grooming strengthens bonds between dairy cows, and age, social rank and repeated grooming between the same animals play a role in those bonds, researchers report in Frontiers in Veterinary Science. The team studied 38 cows at a Chilean agricultural research station, and said the findings underscore the value of monitoring herd interactions and investigating when social grooming declines.

Funding Watch
The National Science Foundation has awarded a $411,058 grant to University of California at Santa Cruz, to study languages that are on the verge of dying out. "We will be investigating a fundamental aspect of cognition: how language users refer to the world around them through their system of pronouns, and how this system is shaped by animacy -- how much something is conceived of as alive or human," says principal investigator Maziar Toosarvandani.
