Biologists have revealed for the first time the genetics linking pheromone signals produced by female moths and the neuronal response driving male attraction to females. The ability to predict mate choice will help in understanding how species diverge, and how to control agricultural pests.
A family of proteins that sense mechanical force--and enable our sense of touch and many other important bodily functions--also are essential for proper root growth in some plants, according to a study led by scientists at Scripps Research and Howard Hughes Medical Institute.
A team of evolutionary biologists has shown that Anolis lizards, or anoles, are able to breathe underwater with the aid of a bubble clinging to their snouts. Some anoles are stream specialists, and these semi-aquatic species frequently dive underwater to avoid predators, where they can remain submerged for as long as 18 minutes. The researchers termed the process 'rebreathing' after the scuba-diving technology.
New research led by the University of Kent has found that people fail to recognise the role of factory farming in causing infectious diseases.
Wild orangutans are known for their ability to survive food shortages, but scientists have made a surprising finding that highlights the need to protect the habitat of these critically endangered primates, which face rapid habitat destruction and threats linked to climate change.
The first frost of autumn may be grim for gardeners but the latest evidence reveals it is a profound event in the life of plants.
A plant cell wall's unique ability to expand without weakening or breaking is due to the movement of its cellulose skeleton, according to new research that models the cell wall. The new study, by Penn State researchers, presents a new concept of the plant cell wall, gives insights into plant cell growth, and could provide inspiration for the design of polymeric materials.
Scientists help protect sharks by developing aquarium breeding programs that pair up individuals in ways that increase genetic diversity. In a new study in Scientific Reports, scientists undertook the largest-ever effort to artificially inseminate sharks.Their work resulted in 97 new baby sharks, including ones whose parents live on opposite sides of the country and a few that don't have fathers at all.
Radical changes to the food system are needed to safeguard our food supply and combat malnutrition in the face of climate change, environmental degradation and epidemics, says new report.
Fossilised footprint tracks, recently discovered within the Hanna Formation in Wyoming, USA, which have been dated to 58 million years ago, may represent the earliest evidence of mammals gathering by the sea, according to a study published in Scientific Reports. Findings suggest that mammals may have first used marine habitats at least 9.4 million years earlier than previously thought, in the late Paleocene (66-56 million years ago), rather than the Eocene (56-33.9 million years ago).
