When it comes to getting treatment for cancer treatment, your marital status could be making a significant difference in the level of medical care you get, finds a new analysis.

The stakes are high, given that 45 percent (<111 million) U.S. adults are unmarried and given the demographic trend among young people that number is likely to rise.

After Friedrich Wohler accidentally synthesized urea in 1828, chemical synthesis - and organic synthesis for that - has been a driving force in pharmaceutical innovation.

We live longer and better than ever and we can thank the continuous advancement of synthetic chemistry, which allows scientists to design and build new molecules.

When we think of marsupials (carrying young in a pouch) they are small and cute (opossum, wombat) to a little more menacing (kangaroos in boxing gloves) but nothing like Palorchestid marsupials, an extinct group of Australian megafauna, who were large, had strange tapir-like skulls, and large claws.

Over the course of their evolution, palorchestids grew even larger and stranger. Using limb proportions as a proxy for body size, these authors estimated that the latest and largest of the palorchestids weighed over 2,000 lbs. Furthermore, their forelimbs were extremely muscular and were likely adapted for grabbing or scraping at leaves and branches.

No matter how far back in recorded time you go, you were once an intruder. Native Americans of 1800 were genetically different from the natives who lived in North America of 1600, who had little in common with those 1400. Yet none of them were original settlers.

And when we think of Vikings, we think of ancient people hundreds of years before that, but they were once intruders too, and they caused a unique population of Icelandic walrus to disappear 1,100 years ago as they expanded. 

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.
