How did life originate? Ancient proteins may hold important clues. Every organism on Earth is made up of proteins. Although all organisms—even single-celled ones—have complex protein structures now, this wasn't always the case.

Plants have small pores on the underside of their leaves, known as stomata. When the sun rises, these pores open and the plants absorb carbon dioxide (CO2) from the atmosphere, which they need, in addition to sunlight and water, for photosynthesis. At the same…

A research team has published a study in Nature Communications detailing the development of a novel genetically encoded fluorescent sensor for real-time, cell-type-specific monitoring of intracellular adenosine (iAdo).

A conversation between a Tasmanian farmer and a researcher at the Tasmanian Institute of Agriculture (TIA) about the real cost of achieving net-zero emissions led to a multi-year study.

A team of biophysicists has published a step-by-step guide for the reliable cultivation of the unicellular green alga Chlamydomonas reinhardtii. The guide will support researchers worldwide in the fields of life sciences, biophysics, and bioengineering in…

Radiation sterilization technology destroys the DNA and cellular structures of bacteria and microorganisms using electromagnetic waves with far higher energy than ultraviolet radiation. This technique has become indispensable for sterilization in various…

Researchers have uncovered a "selfish" X chromosome in the fruit fly Drosophila testacea that manages to distort inheritance in both sperm and eggs.

A joint research team from the Institute of Biophysics of the Chinese Academy of Sciences and the Beijing Institute of Technology has uncovered a pivotal mechanism by which bacteria defend themselves against viral infection.

Just as human infants rely on their environment and social interactions to acquire speech, bat pups depend on their social environment for vocal learning. New research reveals that in the bat species Saccopteryx bilineata, maternal feedback influences vocal…

The genome structure—how genes are organized within DNA sequences in an organism—is fundamental to the processes and functions of organisms.

Research from the University of Adelaide shows microbial communities in echidna pseudo-pouches undergo dramatic changes while the animal is lactating, which could help in creating an environment for their young, known as puggles, to thrive.

As they digest grass and hay, cows produce significant amounts of methane, a greenhouse gas. In the quest to identify an alternative livestock feed, seaweed has emerged as a promising contender.

A non-toxic, environmentally friendly method of controlling weeds and pests in horticultural crops that has already proved successful in the United States and Europe will now be tested in Australia through a project led by La Trobe University. The five-year…

Ever wonder how many trees stand tall in North America's vast boreal forest? A new University of Alberta study has the answer, and it could benefit climate mitigation. The work is published in the journal Ecography.

Researchers led by the Institute of Marine Research in Norway report an 800 km poleward shift in the spawning grounds of Norwegian spring-spawning herring (NSS herring) following a loss of collective migration memory among older fish due to age-selective…

A recent study by Keifeng Yu and his colleagues, published in Acta Geologica Sinica, describes the discovery and identification of 12 new dinosaur teeth from the Upper Cretaceous Nenjiang Formation. The Cretaceous dinosaurs were identified as belonging to five…

A review of digital technologies in the International Journal of Agricultural Resources, Governance and Ecology suggests that integration of mobile, 5G, wireless and the so-called metaverse could be a turning point in global agriculture. The use of this kind…

Flamingos standing serenely in a shallow alkaline lake with heads submerged may seem to be placidly feeding, but there's a lot going on under the surface.

Researchers at the University of Agder (UiA) and Uppsala University are examining hundreds of snakes from museum collections. They are looking for traces of a deadly fungal disease.

In two recent studies, scientists from the Museum für Naturkunde Berlin have identified and described 40 previously unknown moth species from the Philippines. The newly discovered species belong to the snout moth family (Crambidae), a diverse and often…
