The final results of of the latest annual Pesticide Residue Monitoring Program found that samples are again below the tolerance levels set by the EPA.

The FDA evaluates foods annually for pesticide residues. Final results from the surveys are released after they have undergone a thorough quality assurance review.

But organic pesticides are not separated out. However, there is no reason to believe organic farmers are under any less cost pressure than regular farmers. Both have to maximize yields while minimizing costs and for farmers that often means real-time data on soil conditions and problems in order to use as few costly chemicals as possible. 

At the Ubicomp 2019 conference,University of Massachusetts Amherst graduate students Ali Kiaghadi and S. Zohreh Homayounfar debuted health-monitoring sleepwear they call "phyjamas."

The electronically active garments contain unobtrusive, portable devices for monitoring heart rate and respiratory rhythm during sleep.

The inventors designed a new fabric-based pressure sensor and combined that with a triboelectric sensor - one activated by a change in physical contact - to develop a distributed sensor suite that could be integrated into loose-fitting clothing like pajamas. They also developed data analytics to fuse signals from many points that took into account the quality of the signal coming in from each location.

Projects and welfare systems established to provide support by normalizing disabled people instead contribute to their further marginalization, finds a new analysis.

The paper in Organization Studies investigated a program that allocated computers to disabled people, to help people improve sociability through electronic interactions.

In 1799, Alexander von Humboldt set sail on a 5-year, 8000-km voyage through Latin America. His journey through the Andes Mountains, captured by his famous vegetation zonation figure featuring Mount Chimborazo, canonized the place of mountains in understanding Earth's biodiversity.  

One puzzle for scientists since von Humboldt 250 years ago, and certainly later with Darwin, Wallace, and Mendel, was global pattern of mountain biodiversity, and the extraordinarily high richness in tropical mountains in particular.

Two new papers focus on the fact that the high level of biodiversity found on mountains is far beyond what would be expected from prevailing hypotheses.

A team of ecologists exposed Zonotrichia leucophrys (white-crowned sparrows) to the seed treatment known as imidacloprid (in the class of insecticides known as neonicotinoids) and say the measured weight mass declined in just a few hours, which led to the birds delaying migration. But their study was so small it can only be considered exploratory.

Neonicotinoids are seed treatments, they were created to reduce broad spectrum spraying, like the dichloro-diphenyl-trichloroethane (DDT) that Nixon appointee William Ruckelshaus banned domestically over the findings of experts in 1972.  But this new paper claims the replacements for broad spraying may be just as harmful. 

A recent paper has linked two types of heart problems and one of the most commonly prescribed classes of antibiotics.

Data from the U.S. Food and Drug Administration's adverse reporting system plus a private insurance health claims database in the U.S. that captures demographics, drug identification, dose prescribed and treatment duration, identified 12,505 cases of valvular regurgitation with 125,020 case-control subjects in a random sample of more than nine million patients.
