Identifying asteroids on a potential collision course with Earth could be made easier thanks to an advancement in how to track their orbits more precisely.

Apples rank among the world's most valuable fruit crops, with production spanning more than 100 countries. Some apple trees naturally develop into what farmers call "spur-type" varieties—compact trees that are more productive and easier to maintain. But the genetic mechanisms underlying this coveted trait have remained elusive—until now.

An international team of researchers has made new observations of an unusual supernova, finding the most metal-poor stellar explosion ever observed.

A research team has successfully developed a platform capable of scalable, uniform production of organoids that mimic biological functions. Their research has recently been published in the journal Nature Communications.

The small industrious wood ant can do more than just build high nests in spruce forests. A newly published article in the journal Microbial Ecology reveals that ants combat a range of plant diseases, including those affecting apples. At the same time, ants hunt pests like winter moth larvae, which can defoliate apple trees, to feed their larvae. This opens up entirely new perspectives for biological control of plant diseases.

Light-emitting diodes (LEDs) are everywhere in modern life, from smartphones to home lighting. But today's LEDs have a major limitation: when you try to make them brighter by increasing their power, they become less efficient.

New University of Virginia research is pinpointing when young children begin recognizing what they believe to be unfair treatment in the classroom.

Armenians, a population in Western Asia historically inhabiting the Armenian highlands, were long believed to be descendants of Phrygian settlers from the Balkans. This theory originated largely from the accounts of the Greek historian Herodotus, who observed that Armenians were armed in Phrygian fashion when serving in the Persian army. Linguists further supported this theory, suggesting that the Armenian language shares ties with the Thraco-Phrygian subgroup of Indo-European languages.

Cyanobacteria, an ancient lineage of bacteria that perform photosynthesis, have been found to regulate their genes using the same physics principle used in AM radio transmission.

Because of warmer winters, Florida scrub-jays are now nesting one week earlier than they did in 1981. But these early birds are not always getting the worm.
