When it comes to winning evolutionary fitness races, the tortoise once again prevails over the hare. Scientists have found that limiting migrations among populations of bacteria produced better adaptations.
The bacteria that sneak past the brain’s defenses to cause deadly bacterial meningitis are clever adversaries. New research investigates the molecular tricks bacteria use to convince their host that they are harmless and cause disease.
Fifty miles out to sea from San Diego, in the middle of April, under a perfectly clear blue sky, fisheries scientists leaned over the side of a rubber inflatable boat and lowered a juvenile loggerhead sea turtle into the water. That turtle was a trailblazer — the first of its kind ever released off the West Coast of the United States with a satellite transmitter attached.
Researchers realize that biomass feedstock will need to come from many different sources, in order to meet the revised Renewable Fuel Standard mandating the production of 36 billion gallons of biofuel by the year 2022. The concern remains over converting land from food crops to energy crops. Now a crop scientist, interested in a possible bioenergy feedstock/vegetable double-cropping system, has found promising results in such a system using pumpkin as the vegetable crop.
New research shows how a single growth factor receptor protein programs the entire genome. The study provides evidence that it all begins with a single “master” growth factor receptor that regulates the entire genome.
The Mycosplasma bacteria are the smallest self-replicating organisms. They lack a cell wall, making them resistant to almost all antibiotics, and infections caused by Mycoplasma in livestock result in annual multimillion euro losses in Europe and throughout the world. Although there are vaccines against two species of Mycoplasma that affect pigs and poultry, no vaccines exist for many Mycoplasma species that affect not only livestock but also pets and humans.
A new gene that enables plants to regulate their growth in different temperatures has been discovered by scientists. The researchers said the findings provided insights into how plants modulate their growth, and could lead to scientists designing plants that could withstand elevated temperatures.
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.
