The most populated areas of Puget Sound have experienced striking shifts in marine species, with declines in herring and smelt that have long provided food for other marine life and big increases in the catch of jellyfish, which contribute far less to the food chain, according to new research that tracks species over the last 40 years.
Research by environmental scientists finds that potentially harmful growth-promoting hormones used in beef production are expected to persist in the environment at higher concentrations and for longer durations than previously thought.
An egg is many things. It is a versatile food but also an efficient source of bioactive compounds. A researcher has discovered that fractions isolated from the ovomucin protein in egg white can inhibit virus growth.
The ability that some people have to use echoes to determine the position of an otherwise silent object, in a similar way to bats and dolphins, requires good high-pitch hearing in both ears, according to new research. This builds on recent research that demonstrated conclusively that some sighted and blind people could use echoes in this way. What wasn’t clear until now was how important high-frequency hearing in both ears is.
Researchers have developed artificial membranes with programmable features, enabling studies of cell communication and the molecular basis of disease. The new study demonstrates how researchers can examine the interactions of cell surfaces with other biological molecules, with far ranging applications in medicine, biochemistry and biophysics.
A group of leading soil scientists points out the precarious state of the world’s soil resources and the possible ramifications for human security.
The popularity of bamboo landscaping could increase the spread of hantavirus, researchers say, with the plant’s prolific seed production creating a population boom among seed-eating deer mice that carry the disease.
A group of researchers from the US and Australia have announced the unexpected discovery of exotic ‘vinegar flies’ (drosophilids) in urban Los Angeles. How could these species of one of the world’s most studied organisms have escaped notice for so long in a place like Los Angeles? It all depends on how you look, the researchers say.
Scientists have found that baicalein significantly lowers eye pressure and may act as an all-natural treatment for glaucoma.
Marine scientists have long known that some species of fish possess a unique physiological characteristic — a web of arteries and veins lying very close together — that enables them to raise their internal temperatures higher than that of the water surrounding them. Now, a new study has demonstrated that species possessing the ability to warm their core — a process called endothermy — are able to swim two and a half times faster than those whose body temperature doesn’t change.
