CHAMPAIGN, Ill. -- Crop modeling is essential for understanding how to secure the food supply as the planet adapts to climate change. Many current crop models focus on simulating crop growth and yield at the field scale, but lack genetic and physiological data, which may hamper accurate production and environmental impact assessment at larger scales.
With primary and general elections on the horizon across the U.S., the American Geriatrics Society (AGS) today released a series of high-priority questions for candidates. The AGS candidate question guide is aimed at helping Americans keep all political leaders--including and perhaps especially those running for president--committed to a clear, articulated vision how they will support us all as Americans age.
In the past couple of years, if you lived in a major, or even mid-sized city, you were likely familiar with bike-share bikes.
Whether propped against a tree, strewn along the sidewalk or standing “docked” at a station, the often brightly colored bikes with whimsical company names promised a ready means to get from Point A to Point B.
Like crystal balls for the universe's deeper mysteries, galaxies and other massive space objects can serve as lenses to more distant objects and phenomena along the same path, bending light in revelatory ways.
Gravitational lensing was first theorized by Albert Einstein more than 100 years ago to describe how light bends when it travels past massive objects like galaxies and galaxy clusters.
AMHERST, Mass. - A new study reported this week by evolutionary ecologist Lynn Adler at the University of Massachusetts Amherst and Rebecca Irwin of North Carolina State University, with others, suggests that flower strips - rows of pollinator-friendly flowers planted with crops - offer benefits for common Eastern bumblebee (Bombus impatiens) colony reproduction, but some plants do increase pathogen infection risk.
Fusarium wilt is one of the most economically important diseases of watermelon and a major problem to growers worldwide. In the past, watermelon growers based in the Southeastern United States were able to use methyl bromide to manage this disease, but this is no longer an option due to environmental concerns.

1. ACP: Evidence does not support the use of hydroxychloroquine alone or in combination with azithromycin for prophylaxis or treatment of COVID-19
Scientists are working to find ways to monitor ammonia - an increasing species in the atmosphere closely linked to water eutrophication, soil acidity, and biodiversity loss. But measuring ammonia is not easy because ammonia can change from gas to particles quickly in the air.
Although there are accurate methods to determine ammonia in the lab with the aid of a pump, they are unsuitable for long-term measurements and for large-scale surveys in the field, due to the cost, particularly in terms of manpower, and the need for constant power supply.
Plenty of theories, but nobody knows exactly why we sleep. One thing we know for sure: sleepless nights will not help you make it through the day. There have been many studies exploring how sleep works in the brain and what its purposes are. However, how the synapse - the fundamental building block of the brain contributing to the formation of neuronal circuits - works in relation to sleep has been poorly understood.
n an article published today in Cell Host and Microbe, Professor Subbarao stressed the importance of detecting a neutralising antibody response in recovered COVID-19 patients, and of studies of COVID-19 vaccines in animal models.
Neutralising antibodies prevent infection by binding to a virus and blocking their ability to infect. After an infection, a host can produce neutralising antibodies to protect against future infection.
DALLAS, May 14, 2020 -- People with Type 2 diabetes, but not those with prediabetes, had worse cognitive performance three to six months after a stroke than those with normal fasting blood sugar levels, according to new research published today in Stroke, a journal of the American Stroke Association, a division of the American Heart Association.
Research from the University of Sheffield has revealed why some bird species take longer to develop than others
Findings could help scientists predict how animals will adapt to climate breakdown and habitat destruction
The study is the first to consider the importance of lifestyle, environment, evolutionary history and body size when explaining variation
A team of biochemists and virologists at Goethe University and the Frankfurt University Hospital were able to observe how human cells change upon infection with SARS-CoV-2, the virus causing COVID-19 in people. The scientists tested a series of compounds in laboratory models and found some which slowed down or stopped virus reproduction. These results now enable the search for an active substance to be narrowed down to a small number of already approved drugs. (Nature DOI: 10.1038/s41586-020-2332-7).
A new proof-of-concept study published in the May issue of The Journal of Nuclear Medicine has demonstrated that molecular imaging can be used for identifying early response to 177Lu-DOTATATE treatment in neuroendocrine tumor patients.
The optimal minimum legal age for non-medical cannabis use is 19 years of age, according to a study published in BMC Public Health.
A team of researchers at the Memorial University of Newfoundland, Canada, investigated how Canadians who started using cannabis at several young ages differed across important outcomes (educational attainment, cigarette smoking, self-reported general and mental health) in later-life.
