Consensus is growing in recent research evaluating the impact of right-to-carry concealed handgun laws, showing that they increase violent crime, despite what older research says.
Mathematical models have proven the risk of the on-going pneumonic plague epidemic in Madagascar spreading elsewhere in the world is limited, with the estimated number of exported cases staying below 0.1 person in each country between Aug. 1 and Oct. 17.
Confirmatory HIV testing can substantially reduce the number of infants in South Africa who may be falsely diagnosed as HIV-infected and started on unneeded treatment, according to a new study published this week in PLOS Medicine by Lorna Dunning of the University of Cape Town, South Africa, and colleagues. Confirmatory testing is recommended by the World Health Organization and South African guidelines, but in many settings, uptake is low.
A new computational model of heart tissue allows researchers to estimate the probability of rare heartbeat irregularities that can cause sudden cardiac death. The model, developed by Mark Walker and colleagues from Johns Hopkins University, Baltimore, and IBM Research, Yorktown Heights, N.Y., is presented in PLOS Computational Biology.
Fishermen have no way of separating the fish they catch when they cast their nets at sea. Protected species with no market value end up being trapped and dying for no reason. In an attempt to minimize this incidental fishing, statisticians from UNIGE, Dalhousie University and the Australian National University have devised a new statistical method for predicting bycatches more accurately in the future. The technique can also be applied to other research fields.
Last month, the Bodleian Library at Oxford University announced that a Sanskrit manuscript housed in the library for the last century contains the oldest known written zero, although not a 'true' zero. An international group of historians of Indian mathematics has now challenged those findings.
In the present paper, the concept of 'situation' translates into one of a 'stochastic environment', and three levels of information are systematically studied (minimum, sequential, maximum).
New research by the University of Kent, Butterfly Conservation and the Centre for Ecology & Hydrology shows that citizen scientists can play a role in gathering meaningful information to inform long-term monitoring of biodiversity trends such as butterfly population change.
Hokkaido University scientists has developed a new mathematical model which accurately forecast that a devastating cholera epidemic in Yemen would peak by early July, the 26th week of 2017 and the cumulative incidence would be the order of 700-800 thousand cases.
University of Leicester research suggests that greater access to higher education can influence political outcomes.
