Donors more likely to give to COVID causes when font matches message
- ScienceDaily
- 20/10/6 21:35
Appeals seeking donations to help fight hunger during the COVID-19 pandemic were more successful when the typeface in which the appeal was written mirrored the tone of the donation request, a new study has found.
A simple enrollment change yields big dividends in children's early learning program
- ScienceDaily
- 20/10/6 21:35
Researchers know that texting programs can greatly benefit young children's literacy. Now new research shows that parents' participation in such programs can be boosted exponentially with one simple tweak: automatic enrollment, combined with the ability to opt out.
Pesticides and food scarcity dramatically reduce wild bee population
- ScienceDaily
- 20/10/6 21:35
The loss of flowering plants and the widespread use of pesticides could be a double punch to wild bee populations. In a new study, researchers found that the combined threats reduced blue orchard bee reproduction by 57 percent and resulted in fewer female offspring.
Hospitalized COVID-19 patients are younger, healthier than influenza patients, study finds
- ScienceDaily
- 20/10/6 21:35
Patients hospitalized with COVID-19 were more often male, younger, and had fewer underlying medical conditions than hospitalized influenza patients, a new study found.
Underwater robots to autonomously dock mid-mission to recharge and transfer data
- ScienceDaily
- 20/10/6 21:35
Robots exploring deep bodies of water can only go so far before needing to recharge and upload data. Purdue University engineers have designed a mobile docking station system that would help them go farther.
Experiments with twisted 2D materials catch electrons behaving collectively
- ScienceDaily
- 20/10/6 21:35
A team reports that carefully constructed stacks of graphene -- a 2D form of carbon -- can exhibit highly correlated electron properties. The team also found evidence that this type of collective behavior likely relates to the emergence of exotic magnetic states.
Remote control of blood sugar: Electromagnetic fields treat diabetes in animal models
- ScienceDaily
- 20/10/6 21:35
Researchers may have discovered a safe new way to manage blood sugar non-invasively. Exposing diabetic mice to a combination of static electric and magnetic fields for a few hours per day normalizes blood sugar and insulin resistance. The unexpected and surprising discovery raises the possibility of using electromagnetic fields (EMFs) as a remote control to manage type 2 diabetes.
