They build among the tallest non-human structures (proportionately speaking) in the world and now a pioneering study has found the termites that live in Australia's remote Top End originated from overseas -- rafting vast distances and migrating from tree-tops to the ground, as humans later did. They adapted to significant environmental changes, including increasingly arid conditions and changed from wood- to grass-eaters, with their ground-based fortresses are now a prominent feature of remote areas 'Down Under'.
Hospitals can improve patient care and reduce costs associated with coronary angioplasty if cardiologists perform more of these procedures through an artery in the wrist and if they take steps to discharge such patients on the same day, according to a new study.
A superfluid, which resembles brain tissue, makes ultrasound images easier to interpret during an operation. This will make it easier for surgeons to remove brain tumors more accurately, say researchers.
Researchers have described how infectious bacteria can sense they’re attached to our intestinal cells, and then remodel their expression of specific genes, including those involved in virulence and metabolism, to exploit our cells and colonize our gut.
Survival instinct does not influence species cooperative breeding decisions, a new study has found. Instead, it has found communal living and helping behavior, to be a natural result of monogamous relationships reinforcing stronger genetic bonds in family groups. Siblings with full biological ties are more likely than others to stay with their family, than they are to break away. This is particularly beneficial in harsh environments, like the desert, but not the overall reason why they choose to live in this way.
Researchers demonstrate, for the first time that inhaled resveratrol treatments slow aging-related degenerative changes in mouse lung. Lung aging, characterized by airspace enlargement and decreasing lung function, is a significant risk factor for chronic human lung diseases.
Little is known about the heaviest, radioactive elements in Mendeleev's table. But an extremely sensitive technique involving laser light and gas jets makes it possible for the very first time to gain insight into their atomic and nuclear structure.
In a land where survival is precarious, Komodo dragons thrive despite being exposed to scads of bacteria that would kill less hardy creatures. Now in a study, scientists report that they have detected antimicrobial protein fragments in the lizard's blood that appear to help them resist deadly infections. The discovery could lead to the development of new drugs capable of combating bacteria that have become resistant to antibiotics.
Everyday in the workplace, colleagues actively compete for a limited amount of perks, including raises, promotions, bonuses and recognition. But new research shows that, more than often than not, people fall short in determining which co-workers might be trying to edge them out on the job.
Dive bombing a much larger bird isn't just a courageous act by often smaller bird species to keep predators at bay. It also gives male birds the chance to show off their physical qualities in order to impress females, according to new research on predator mobbing behavior of birds where potential prey approach and harass would-be predators such as owls.
Two drugs used to treat asthma and allergies may offer a way to prevent a form of pneumonia that can kill up to 40 percent of people who contract it, researchers at the University of Virginia School of Medicine have found.
We use others' eyes -- whether they're widened or narrowed -- to infer emotional states, and the inferences we make align with the optical function of those expressions, according to new research. The research reveals, for example, that people consistently associate narrowed eyes -- which can enhance visual discrimination -- with discrimination-related emotions including disgust and suspicion.
Researchers have demonstrated how harmful health complications passed from mother rats to their offspring can be reversed. The tests may point the way toward preventing the transfer of certain health conditions from human mothers to their children.
