As American consumers turn to online search engines for cheaper prescription drugs from foreign pharmacies, safety and quality concerns arise. In 2010, Google banned sponsored search advertising by pharmacies that are not certified by the National Association of Boards of Pharmacy (NABP). Soon, other major search engines followed. But a forthcoming study in the INFORMS journal, Marketing Science, a leading scholarly marketing publication, finds that the ad ban had limited success in reducing access.
Researchers investigates the properties of gravitational waves and binary black holes if they formed inside a collapsing star.
Research teams all over the world are exploring different ways to design a working computing chip that can integrate quantum interactions. Now, Australian and Dutch engineers believe they have cracked the problem, reimagining the silicon microprocessors we know to create a complete design for a quantum computer chip that can be manufactured using mostly standard industry processes and components.
A scientist from Siberian Federal University (SFU) and his colleagues from Austria and Germany constructed a physical and mathematical model of Mars- and Venus-sized planet formation. The team concluded that Mars had no chances to develop a thick atmosphere and biosphere. In the case of Venus it depended on solar activity: according to the scientists, it managed to keep its atmosphere due to the fact that young Sun was not very active. The study was published in Icarus.
While free or low cost music streaming sources like Spotify decrease the use of paid music platforms, such as iTunes, a new study in the INFORMS journal Marketing Science, shows they significantly increase exposure for and access to lesser known or indie artists that fall outside the top 100 or even top 500 listings.
The elementary particles of 'new physics' must be so massive that their detection in the LHC, the largest modern accelerator, will not be possible. This none- too-optimistic conclusion comes from the most comprehensive review of observational data from many scientific experiments and their confrontation with several popular varieties of supersymmetry theory. The complicated, extremely computationally demanding analysis was carried out by the team of the international GAMBIT Collaboration -- and leaves a shadow of hope.
QUT robotics researchers have developed new technology to equip underground mining vehicles to navigate autonomously through dust, camera blur and bad lighting.
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.
