MIT researchers can now predict how much energy solar cells will produce at any location worldwide. Surprisingly, they identified that two types of solar cells can vary in energy output by 5 percent or more in tropical regions. This gap occurs because solar energy can shift depending on local temperature and water in the atmosphere. Their work, appearing in Joule, emphasizes that solar products may behave differently depending on their environment.
With revenue from college football at an unprecedented $3.4 billion annually, universities across the country invest millions each year in recruitment efforts for high school football players. But with talented players typically receiving multiple scholarship offers, team rosters are in limbo until student athletes commit to a university. However, a new study in the INFORMS journal Decision Analysis shares how social media can provide universities with valuable insight into the decision-making process of their recruits.
While a strong infrastructure is important for healthcare, measures of health facility infrastructure are poorly correlated with health system quality, according to a new study published this week in PLOS Medicine by Hannah Leslie from the Harvard T.H. Chan School of Public Health, USA, and colleagues.
Few people draw a parallel between bumblebees and travelling salesmen but that's what comes after months of tracking the flight paths of the foraging pollinators as they refine their routes around multiple destinations and, in the process, provide insights into analogous problems in logistics and robotics and into how land might be used more efficiently.
Researchers from the University of Texas at Austin and the City of Austin have developed a tool that uses artificial intelligence to recognize objects in raw traffic camera footage and characterize how those objects move and interact. This information can then be analyzed and queried by traffic engineers and officials to improve the safety and performance of the city's transportation network. The work will be presented at the IEEE Big Data conference this week.
Three billion years ago, the sun shone weaker, but Earth stayed surprisingly warm. Carl Sagan thought a greenhouse effect must have been to thank. A model built on 359 chemical processes has finally arrived at scenarios with a reasonable chance of producing the needed methane on ancient Earth. The model has broad parameters in hope that it may someday be of use to interpret conditions on exoplanets.
Analyzing trends on Twitter and Google can help predict vaccine scares that can lead to disease outbreaks, according to a study from the University of Waterloo.
The job outlook remained positive for Americans with disabilities, with yet another month of gains in the major economic indicators, according to today's National Trends in Disability Employment -- Monthly Update (nTIDE), issued by Kessler Foundation and the University of New Hampshire's Institute on Disability (UNH-IOD). This upward trend now extends to 20 consecutive months of gains in the labor market for people with disabilities.
A new mapping technique, described in the Nov. 14 issue of the Proceedings of the National Academies of Sciences, shows how researchers are developing computational tools that combine cellphone records with data from satellites and geographic information systems to create timely and incredibly detailed poverty maps. Unlike surveys or censuses, which can take years and cost millions of dollars, these maps can be generated quickly and cost-efficiently.
UT Dallas researchers develop speech-processing techniques to reconstruct NASA lunar mission audio from a massive archive. The team developed algorithms to process, recognize and analyze the audio to determine who said what and when in an advance in diarization research.
