PROVIDENCE, R.I. [Brown University] -- Mindfulness-based meditation programs have emerged as a promising treatment for conditions ranging from stress to sleeplessness to depression. In some cases, they're even offered to people -- schoolkids or employees, for example -- who aren't actively seeking help or who haven't been screened for suitability. Yet most research and discourse about these programs focuses only on their benefits, with little investigation of the risks or the potential for adverse effects.
ITHACA, N.Y. - Wines and table grapes exist thanks to a genetic exchange so rare that it's only happened twice in nature in the last 6 million years. And since the domestication of the grapevine 8,000 years ago, breeding has continued to be a gamble.
When today's growers cultivate new varieties - trying to produce better-tasting and more disease-resistant grapes - it takes two to four years for breeders to learn whether they have the genetic ingredients for the perfect flower.
Due to climate change, the average global temperature will rise in the coming decades. This should also significantly increase the number of so-called cooling degree days. These measure the number of hours, in which the ambient temperature is above a certain threshold, at which a building must be cooled to keep the indoor temperature at a comfortable level. The rising values may lead to an increased installation of AC systems in households. This could lead to a higher energy demand for cooling buildings, which is already expected to increase due to climate change and population growth.
Invasions by alien insect and animal species have much in common with outbreaks of infectious diseases and could tell us a great deal about how pandemics spread, according to a research paper published today.
Biological invasions, where animals, insects, plants and microorganisms are transported around the globe by humans, are becoming more common and have a global annual cost of at least £118billion.
The cover for issue 7 of Oncotarget features Figure 5, "SUM149-MA cells surviving a 6-MP treatment are sensitive to chemotherapeutic drugs," published in "Inhibition of resistant triple-negative breast cancer cells with low-dose 6-mercaptopurine and 5-azacitidine" by Singh, et al. which reported that the authors have reported that a lengthy treatment with low-dose 6-mercaptopurine, a clinically useful anti-inflammatory drug, inhibits such resistant cells.
Rice farmers in Nepal are chronically falling short of their potential productivity. Poor rice yields are persistent across the Terai--a lowland region lying south of the outer foothills of the Himalayas that extends through southern Nepal into northern India--and existing decision support systems are failing to provide the precision required.
While some international students come to Canada knowing whether they intend to stay or return home after completing their degrees, the majority decide after they have had a chance to live here for a few years, a new study has found.
"Nearly a quarter of our participants made the decision prior to arriving in Canada," said Elena Neiterman, a lecturer in the School of Public Health and Health Systems at the University of Waterloo. "However, the majority were not certain what their plans for the future were until they had a chance to live here and explore life in Canada."
WASHINGTON, May 18, 2021 -- Wake steering is a strategy employed at wind power plants involving misaligning upstream turbines with the wind direction to deflect wakes away from downstream turbines, which consequently increases the net production of wind power at a plant.
In Journal of Renewable and Sustainable Energy, by AIP Publishing, researchers at the U.S. Department of Energy's National Renewable Energy Laboratory (NREL) illustrate how wake steering can increase energy production for a large sampling of commercial land-based U.S. wind power plants.
What The Study Did: Telemedicine use grew rapidly during the COVID-19 pandemic but there was geographic variation in its use so researchers in this study examined the association of county-level telemedicine use with community factors among people with commercial or Medicare Advantage insurance.

Eating a Western diet impairs the immune system in the gut in ways that could increase risk of infection and inflammatory bowel disease, according to a study from researchers at Washington University School of Medicine in St. Louis and Cleveland Clinic.
Australian scientists have compared an ancient Greek technique of memorising data to an even older technique from Aboriginal culture, using students in a rural medical school.
The research team, led by Academician GUO Guangcan from University of Science and Technology of China (USTC) of the Chinese Academy of Sciences, collaborating with LI Bo from Shangrao Normal University and CHEN Jingling from Nankai University, achieved the masking of optical quantum information. The researchers concealed quantum information into non-local quantum entangled states. The study was published in the journal Physical Review Letters.
Urban megaprojects tend to be the antithesis of good urban planning. They have a negative impact on local water systems, deprive local communities of water-related human rights, and their funders and sponsors have little accountability for their impact.
These are the findings of the University of Adelaide's Dr Scott Hawken from the School of Architecture and Built Environment who led a review of the impact of urban megaprojects on water justice in South East Asia.
"Urban megaprojects have severe implications for environmental processes," said Dr Hawken.
Graphene nanoribbons (GNRs), narrow strips of single-layer graphene, have interesting physical, electrical, thermal, and optical properties because of the interplay between their crystal and electronic structures. These novel characteristics have pushed them to the forefront in the search for ways to advance next-generation nanotechnologies.
With the rise of the digital age, the amount of WiFi sources to transmit information wirelessly between devices has grown exponentially. This results in the widespread use of the 2.4GHz radio frequency that WiFi uses, with excess signals available to be tapped for alternative uses.
