New test by deepest galaxy map finds Einstein’s theory stands true

Wed, 05/11/2016 - 12:41
Astronomers have made a 3D map of 3000 galaxies 13 billion light years from Earth, and found that Einstein's general theory of relativity is still valid.

How to boost online ratings

Wed, 05/11/2016 - 12:07
Consumers are more likely to give a positive review if they experience time and space distance before writing a review, new research suggests. In other words, the longer they wait to write a review, the better the evaluation. The same applies for being father away from a service experience.

Real-time influenza tracking with 'big data'

Wed, 05/11/2016 - 12:07
Cloud-based data from electronic health records can be used to pick up cases of influenza in real time, at least one week ahead of CDC reporting, a new study demonstrates.

Biomedical research streamlined by making genetic data easier to search

Tue, 05/10/2016 - 17:43
A team of scientists is expanding web services to make biomedical research more efficient. With their free, public projects, and, researchers around the world have a faster way to spot new connections between genes and disease.

Math, not skin, may be a better way to help researchers test consumer products, study shows

Tue, 05/10/2016 - 17:28
Researchers are presenting collaborative research on the use of mathematical methods for understanding the transportation of chemical compounds in biological tissues, like the skin. This could lead to better ways of testing cosmetic or consumer products without harming humans or animals.
