Australia needs to urgently prioritize state and national conservation policies, according to a new study, with the findings warning that more than 220 critically endangered species are at risk of being lost due to their small distributions coupled with u

A group of fossils of elasmosaurs—some of the most famous in North America—have just been formally identified as belonging to a "very odd" new genus of the sea monster, unlike any previously known.

ARS scientists made a "sweet" discovery that may be important to solving a major problem within the citrus industry.

The northern white rhinoceros is one of the rarest animals on Earth, with just two females left and no natural way for the species to reproduce.

A study has found that an ancient protein motif that binds to nucleic acids is functionally "ambidextrous." This means that the motif can interact with both natural and mirror-image nucleic acids, an occurrence that has never before been reporte

Roots "feel" gravity to extend and anchor themselves in the soil, but they can alter their growth direction toward a water source when needed. However, according to a new study by scientists at the Institute of Science and Technology Austria (IS

When trees and soil fungi form close associations with each other, both partners benefit. Many tree species have further enhanced this cooperation by forming a concurrent symbiosis with two different groups of mycorrhizal fungi. Those trees cope better wi

Nestled in dark burrows, with a limited sense of vision, mice brush their whiskers against their environment to navigate and to detect objects around them. This behavior, termed whisking, has been extensively studied in the past few decades and has tradit

Researchers at the Francis Crick Institute have developed a new stem cell model of the mature human amniotic sac, which replicates development of the tissues supporting the embryo from two to four weeks after fertilization. This is the first model of amni

Language processing in humans depends on the neuronal connection between language areas in the brain. Until recently, this language network was thought to be uniquely human.

A new study has compared how migrating humpback whales use two stopover sites along the Queensland coast, finding that one was more social in nature and the other was used primarily by mothers and calves.

Auxin is the first plant hormone—or "phytohormone"—ever identified, with its discovery dating to the late 19th and early 20th centuries. With its discovery, scientists began to understand how small, self-produced organic molecules could influenc
