CHAMPAIGN, Ill. -- A multidisciplinary group that studies the physical and chemical properties of insect wings has demonstrated the ability to reproduce the nanostructures that help cicada wings repel water and prevent bacteria from establishing on the surface. The new technique - which uses commercial nail polish - is economical and straightforward, and the researchers said it will help fabricate future high-tech waterproof materials.
Based on digital endocranial cast models the canine brain does not increase proportionally with body size. Researchers at ELTE Eötvös Loránd and Kaposvár University in Hungary reconstructed the surface morphology of 28 canine brains, including various dog breeds, wolves, coyotes, and jackals. The shortening of the facial skeleton greatly influences the ratio of certain brain regions, primarily the olfactory bulb and the frontal lobe. These changes might have profound implications for olfactory and problem-solving abilities.
OCTOBER 22, 2020 - Nutley, NJ - A more efficient and much faster method to assess high levels of neutralizing antibodies to COVID-19 could point the way to better understanding and treatment of the disease, according to new published findings by scientists from the Hackensack Meridian Center for Discovery and Innovation (CDI) and the University of Michigan (U-M).
A new discovery about how the body transports dexamethasone, a drug that can increase the survival chances of patients with severe COVID-19, suggests diabetes and other factors may reduce its potentially lifesaving effectiveness. Based on their findings, the researchers say doctors may need to rethink how they dose the drug for certain groups of patients.
Being highly connected to a strong social network has its benefits. Now a new University of Alberta study is showing the same goes for trees, thanks to their underground neighbours.
The study, published in the Journal of Ecology, is the first to show that the growth of adult trees is linked to their participation in fungal networks living in the forest soil.
DURHAM, N.C. -- A team of Duke University researchers has developed a lab-grown living lung model that mimics the tiny air sacs of the lungs where coronavirus infection and serious lung damage take place. This advance has enabled them to watch the battle between the SARS-CoV-2 coronavirus and lung cells at the finest molecular scale.
UNIVERSITY PARK, Pa. -- A new tool created by researchers at Penn State and Houston Methodist Hospital could diagnose a stroke based on abnormalities in a patient's speech ability and facial muscular movements, and with the accuracy of an emergency room physician -- all within minutes from an interaction with a smartphone.
WASHINGTON, Oct. 22, 2020 -- Over the last century, the compound ammonium nitrate has been involved in at least 30 disasters and terrorist attacks. Under normal circumstances, it's totally harmless and used in things like fertilizer, so what makes ammonium nitrate turn deadly?: https://youtu.be/-SeT3N3A19c.
Conducted by an international consortium, led by the London School of Hygiene & Tropical Medicine and the University of Maryland School of Medicine, the research is the first meta-analysis of preventive malaria treatments among school-age children.
The team pooled data from 11 different clinical studies that tested malaria preventative medications in 15,000 children aged 5 to 15 living in seven different countries across sub-Saharan Africa. Half were given preventive malaria treatment, whereas the other half were either given a placebo or not treated as a control.
Doctors and biostatisticians at the University of Michigan Rogel Cancer Center have led the development and validation of a staging system to better predict outcomes and inform treatment decisions for men diagnosed with non-metastatic prostate cancer.
Although it is one of the most common cancers worldwide, prostate cancer remains one of the few major cancers for which the familiar, numerical staging system -- ranging from stage 1 to stage 4 -- has not been adopted into national guidelines for treatment or for the testing of new medicines in clinical trials.
White Americans support strict immigration policies while at the same time favor the DREAM Act that would grant legal status to some immigrants who were brought to the United States as children, a contradiction linked to racial resentment and the belief that equality already exists, according to a Rutgers-led study.
SPOKANE, Wash. - Increasing the amount of time spent asleep immediately after a traumatic experience may ease any negative consequences, suggests a new study conducted by researchers at Washington State University's Elson S. Floyd College of Medicine.
'Mini-lungs' grown from tissue donated to Cambridge hospitals has provided a team of scientists from South Korea and the UK with important insights into how COVID-19 damages the lungs. Writing in the journal Cell Stem Cell, the researchers detail the mechanisms underlying SARS-CoV-2 infection and the early innate immune response in the lungs.
New research from an immunology team at the University of Chicago may shed light on the challenges of developing a universal flu vaccine that would provide long-lasting and broad protection against influenza viruses.
Despite having bat-like wings, two small dinosaurs, Yi and Ambopteryx, struggled to fly, only managing to glide clumsily between the trees where they lived, according to a new study led by an international team of researchers, including McGill University Professor Hans Larsson. Unable to compete with other tree-dwelling dinosaurs and early birds, they went extinct after just a few million years. The findings, published in iScience, support that dinosaurs evolved flight in several different ways before modern birds evolved.
