University College Dublin is Ireland's largest university, with research institutes spanning medicine, agriculture, science and the humanities.
Researchers at UCLA and UC Santa Barbara report in Science that the rare 15N15N form of nitrogen gas tracks how much nitrogen microbes convert to gas. Air dissolved in water normally hides that microbial gas, so the signal shows nitrogen removal that conventional methods obscure.

Bat1K researchers' Nature study of 103 genomes and 44 fossils puts the most likely origin of bats in Europe, 65 to 60 million years ago. The same model places powered flight and echolocation near the root of the tree, before modern bat groups began to split.

A UCD-led team read 3,500 years of sheeppox evolution out of manuscript skins and Bronze Age sheep teeth, which puts a dated, provenanced sampling frame for livestock disease inside library reading rooms.

The Bat1K consortium's Nature paper samples every one of the 21 recognised bat families and dates the group to roughly 65 million years ago, with the geography resting on where 44 fossil bats were found.

Tadhg O'Keeffe dated the oldest fabric inside University College Dublin's Roebuck Castle to the early 13th century after matching medieval features under its plaster against Gabriel Beranger's watercolours of the ruins from about 1765.

Ilias Dimeas and colleagues counted 232 plastic particles in lung washings and biopsies from 100 people already being scoped for symptoms, which earns the follow-up experiments they have started but not a claim about cause.
Reality
Polyploidy kills most of the organisms it visits. Its survivors include every seed plant alive. Maurine Neiman's snails are recent enough to watch closely, but that closeness does not explain why doubling keeps recurring.
Reality
A researcher with seven years of four-day-week pilot data says the four-day-week evidence is strong and the route to it is not, because gains have historically gone to output.

A Trinity College Dublin and UCD team says dietary yeast beta-glucan retrained bone marrow progenitors in obese mice, restoring anti-tumour immunity that weight loss alone did not.
