GAINESVILLE, Fla. --- Birds of a feather don't always flock together: Peer into a forest canopy, and you will likely spot multiple bird species flying and feeding together, a phenomenon most spectacular in the Amazon where 50 species may travel as a unit. But are birds in these mixed flocks cooperating with one another or competing?
A new study suggests both.
Warfighters on the battlefield often rely on machines, vehicles and other technologies with rotating parts to complete their mission. Army researchers have devised a new method of testing for a major factor in equipment failure and breakdown in order to ensure that those tools meet the proper standard of quality.
Transmission of diseases from wildlife to livestock is a common threat in Alberta, according to new research by University of Alberta biologists. Foothills in the southwestern part of the province are home to wild elk as well as cattle on ranchlands--and when the species intermingle, the potential for disease to spread grows.
The Global Precipitation Measurement mission or GPM satellite provided a look at the rainfall occurring within Tropical Cyclone Uesi and found heaviest rainfall in the southern quadrant of the storm.
Uesi is in the South Pacific Ocean and has been affecting New Caledonia. New Caledonia is a collectivity of France, located south of Vanuatu and about 1,210 km (750 miles) east of Australia.
What if the key to a better understanding of schizophrenia has been here all along--but researchers haven't had the resources to study it?
Now, thanks to the pooled data and insights from researchers around the world, USC researchers have the clearest picture yet of brain abnormalities associated with the serious mental illness that impacts 20 million people worldwide.
All the elements are there to begin with, so to speak; it's just a matter of figuring out what they are capable of - alone or together. For Leslie Schoop's lab, one recent such investigation has uncovered a layered compound with a trio of properties not previously known to exist in one material.
CHAMPAIGN, Ill. -- By adding infrared capability to the ubiquitous, standard optical microscope, researchers at the University of Illinois at Urbana-Champaign hope to bring cancer diagnosis into the digital era.
Pairing infrared measurements with high-resolution optical images and machine learning algorithms, the researchers created digital biopsies that closely correlated with traditional pathology techniques and also outperformed state-of-the-art infrared microscopes.
HOUSTON - (Feb. 12, 2020) - You don't need a big laser to make laser-induced graphene (LIG). Scientists at Rice University, the University of Tennessee, Knoxville (UT Knoxville) and Oak Ridge National Laboratory (ORNL) are using a very small visible beam to burn the foamy form of carbon into microscopic patterns.
WASHINGTON, D.C.--The emergency department is being increasingly utilized as a patient's best or only treatment option for opioid use disorder (OUD). New analysis in Annals of Emergency Medicine shows that the prevalence of patients who visited emergency departments at four Indiana hospital systems for repeat opioid-related emergencies jumped from 8.8 percent of all opioid-related visits in 2012 to 34.1 percent in 2017--nearly a four-fold increase in just five years.
Numerous previous attempts to develop therapeutic treatments, directed at discreet targets of the sepsis cascade, could not cope with the complex pathophysiology of sepsis and failed.
Studies in a severe rat sepsis model showed that pre-treatment by NCs led to a dramatic increase in survival, from zero to 75%.
Over a quarter of the remaining endangered Asian elephants in the world live in some form of captivity. The Asian elephant is particularly threatened, its population having halved since the 1950s and its range now only 5 per cent of its original size. The Asian elephant as a species, however, is in a unique position with 24-29 per cent of their remaining population living among humans, in captive or semi-captive conditions. Whilst the conservation priority lies in protecting the dwindling wild population, it is also important to protect these large human-managed populations.
Today, nanoparticles are not only in cosmetic products, but everywhere, in the air, in water, in the soil and in food. Because they are so tiny, they easily enter into the cells in our body. This is also of interest for medical applications: Nanoparticles coated with active ingredients could be specifically introduced into cells, for example to destroy cancer cells. However, there is still much to be learned about how nanoparticles are distributed in the cells, what they do there, and how these effects depend on their size and coating.
Research involving the University of Liverpool has revealed the effect of climate warming on the complex interactions between tree masting and the insects that eat their seeds.
By far the largest proportion of soybeans grown worldwide is used for animal feed. This is particularly problematic because soybean cultivation inflicts massive environmental damage on supplier countries. The Institute of Agricultural and Nutritional Sciences at Martin Luther University Halle-Wittenberg (MLU) is therefore currently researching domestic alternatives as part of the SilaToast project.
DURHAM, N.C. -- Biomedical engineers at Duke University have demonstrated that while different wearable technologies, like smart watches and fitness trackers, can accurately measure heart rate across a variety of skin tones, the accuracy between devices begins to vary wildly when they measure heart rate during different types of everyday activities.
