Washington [US], August 11 (ANI): Anthropology professors and field primatologists have documented the daily life of hundreds of large-brained capuchin monkeys in Guanacaste, Costa Rica. They have found that female capuchin monkeys who are better integrated into social networks with other adult females tend to survive longer.
Washington [US], August 11 (ANI): New research has provided the strongest evidence yet that the earth's continents were formed by giant meteorite impacts that were particularly prevalent during the first billion years or so of our planet's four-and-a-half-billion-year history.
Washington [US], August 10 (ANI): The continents of Earth were formed by gigantic meteorite impacts that were particularly prevalent during the first billion years of our planet's four and a half billion year history, according to new Curtin research, which has presented the strongest proof to yet.
Washington [US], August 10 (ANI): Social hunting strategies are already well documented in many animal species when prey is distributed in an unpredictable way across the landscape. Researchers have now demonstrated for the first time that animals in this case the common noctule bat join together and form a mobile sensory network in order to increase their chances of finding their prey. The analyses show that predators can adjust to variable environmental conditions through flexible foraging strategies by networking with conspecifics.
Washington [US], August 10 (ANI): A historically overlooked rod-like projection present on nearly every cell type in the human body may finally be getting its scientific due: A new study has found that these appendages, called cilia, on neurons in the brain have a key role in ensuring a specific dopamine receptor's signals are properly received.
Washington [US], August 10 (ANI): A molecular pathway responsible for the spread of glioblastoma to surrounding tissue in the brain, as well as an existing drug that curbed tumour growth in animal models, has been identified by UT Southwestern.
Washington [US], August 10 (ANI): A new study based on data tracking hundreds of Philadelphia youth over more than a half-dozen years has detailed the complex pathway connecting impulsivity, alcohol use, and antisocial behaviour.
Washington [US], August 9 (ANI): Cystic fibrosis remains an incurable genetic disorder which impairs lung function and significantly reduces life expectancy. A new combination drug therapy which addresses the disorder's underlying defects offers a promising new treatment approach.
Washington [US], August 8 (ANI): Genetic signatures that can predict whether tumours in patients with bladder and other cancers will respond to immunotherapy have recently been identified by researchers from Cedars-Sinai Cancer.
Washington [US], August 7 (ANI): According to the standard model of cosmology, the vast majority of galaxies are surrounded by a halo of dark matter particles. This halo is invisible, but its mass exerts a strong gravitational pull on galaxies in the vicinity. A new study challenges this view of the Universe. The results suggest that the dwarf galaxies of Earth's second closest galaxy cluster known as the Fornax Cluster are free of such dark matter halos.
Frankfurt [Germany], August 5 (ANI): It is commonly known that bats utilise ultrasonic sounds to orient themselves and use the echoes that follow to create an impression of their environment. For instance, echolocation is used by the Seba's short-tailed bat (Carollia perspicillata) to find the fruits that make up its preferred diet. Bats communicate with one another via vocalising as well. They use a significantly narrower band of frequencies for this.
Washington [US], August 7 (ANI): Why do some people with amyloid plaques in their brains, associated with Alzheimer's disease, show no signs of the disease, while others with the same amount of plaque have clear memory and thinking problems? Researchers looked at genetic and life course factors that may help create a 'cognitive reserve' that provides a buffer against the disease.
Washington [US], August 6 (ANI): Tropical coastal ecosystems are among the most biodiverse areas on Earth. And they're also on the front lines of effects caused by human activity. That's why it's becoming increasingly important, especially as human populations increase, to manage the impacts of runoff and wastewater that flow into the sea.
Cambridge (Massachusetts) [US], August 6 (ANI): According to a recent study, the engineers present the design for a new ultrasound sticker, a stamp-sized device that sticks to the skin and can provide continuous ultrasound imaging of internal organs for 48 hours.
Washington [US], August 6 (ANI): New research suggests that people with elevated levels of the protein prostasin (mainly found in epithelial cells which line the surfaces and organs of the body) may be at higher risk of developing diabetes.
