Flavonoid compounds -- produced by the roots of some sorghum plants -- positively affect soil microorganisms, according to Penn State researchers, who suggest the discovery is an early step in developing a frost-resistant line of the valuable crop for North American farmers.
The larynx is larger, more variable in size, and has undergone faster rates of evolution in primates than in carnivores, according to a study published August 11, 2020 in the open-access journal PLOS Biology by Daniel Bowling of Stanford University, W. Tecumseh Fitch of the University of Vienna, and colleagues.
USC researchers have found the likely order in which COVID-19 symptoms first appear: fever, cough, muscle pain, and then nausea, and/or vomiting, and diarrhea.
Knowing the order of COVID-19's symptoms may help patients seek care promptly or decide sooner than later to self-isolate, the scientists say. It also may help doctors rule out other illnesses, according to the study led by doctoral candidate Joseph Larsen and his colleagues with faculty advisors Peter Kuhn and James Hicks at the USC Michelson Center for Convergent Bioscience's Convergent Science Institute in Cancer.
Nylon manufacture could be revolutionised by the discovery that bacteria can make a key chemical involved in the process, without emitting harmful greenhouse gases.
Scientists have developed a sustainable method of making one of the most valuable industrial chemicals in the world - known as adipic acid - which is a key component of the material.
More than two million tonnes of the versatile fabric - used to make clothing, furniture and parachutes - is produced globally each year, with a market value of around £5 billion.
OAK BROOK, Ill. - There was a higher incidence and severity of physical intimate partner violence (IPV) among patients seen at a large, academic medical center in the U.S. during the COVID-19 pandemic compared with the prior three years, according to a new study published in Radiology.
BOSTON - Investigators led by a team at Massachusetts General Hospital (MGH) have made discoveries at the single cell level to uncover new details concerning mitochondrial diseases-- inherited disorders that interfere with energy production in the body and currently have no cure. The findings, which are published in the New England Journal of Medicine, could eventually benefit affected patients.
Progress against DIPG, a fatal childhood brain tumor, is usually a game of inches. Studies that hint at even small gains are cause for celebration.
That's why researchers at the University of Michigan and their collaborators are excited about discoveries that point toward a new potential treatment approach -- one that significantly lengthened survival times in two mouse models of DIPG.
Adopting a third-person, observer point of view when recalling your past activates different parts of your brain than recalling a memory seen through your own eyes, according to a new paper.
"Our perspective when we remember changes which brain regions support memory and how these brain regions interact together," explained Peggy St Jacques, assistant professor in the Faculty of Science'sDepartment of Psychology and co-author on the paper.
A recent paper published in The Economic Journal indicates that, in families with disabled children, the second born child is more adversely affected cognitively than the first-born child.
CLEVELAND--Luis Ortiz-Rodríguez grew up on the beaches of Puerto Rico--surfing, swimming and running in the hot sand--and swears he had never put on sunblock a day in his life.
Then the day came when he peered through an ultrafast laser spectrometer at the College of Arts & Sciences at Case Western Reserve University and observed and recorded pre-cancerous lesions forming on the DNA within three picoseconds after exposure to ultraviolet light.
That's picosecond, as in one trillionth of a second.
A Princeton team has developed a class of light-switchable, highly adaptable molecular tools with new capabilities to control cellular activities. The antibody-like proteins, called OptoBinders, allow researchers to rapidly control processes inside and outside of cells by directing their localization, with potential applications including protein purification, the improved production of biofuels, and new types of targeted cancer therapies.
WASHINGTON (August 13, 2020)-- An online COVID-19 symptom tracking tool developed by researchers at Georgetown University Medical Center ensures a person's confidentiality while being able to actively monitor their symptoms. The tool is not proprietary and can be used by entities that are not able to develop their own tracking systems.
WASHINGTON -- Researchers have designed an off-grid, low-cost modular energy source that can efficiently produce power at night. The system uses commercially available technology and could eventually help meet the need for nighttime lighting in urban areas or provide lighting in developing countries.
University of Toronto Engineering researchers have developed a new method of injecting healthy cells into damaged eyes. The technique could point the way toward new treatments with the potential to reverse forms of vision loss that are currently incurable.
Around the world, millions of people live with vision loss due to conditions such as age-related macular degeneration (AMD) or retinitis pigmentosa. Both are caused by the death of cells in the retina, at the back of the eye.
PROVIDENCE, R.I. [Brown University] -- As levels of atmospheric carbon dioxide continue to climb, scientists are looking for new ways of breaking down CO2 molecules to make useful carbon-based fuels, chemicals and other products. Now, a team of Brown University researchers has found a way to fine-tune a copper catalyst to produce complex hydrocarbons -- known as C2-plus products -- from CO2 with remarkable efficiency.
