A new study by the U.S. Geological Survey and Centers for Disease Control and Prevention estimates about 2.1 million people in the U.S. may be getting their drinking water from private domestic wells considered to have high concentrations of arsenic, presumed to be from natural sources. “About 44 million people in the lower 48 states use water from domestic wells,” said Joe Ayotte, a USGS hydrologist and lead author of the study. “While we’re confident our research will help well owners understand if they live in an area of higher risk for arsenic, the only way for them to be certain of what’s in their water is to have it tested.” Using a standard of 10 micrograms of arsenic per liter -- the maximum contaminant level allowed for public water supplies -- the researchers developed maps of th

The National Institute of Advanced Industrial Science and Technology (AIST) Kansai in Osaka Prefecture has succeeded in making hens lay eggs that contain a pharmaceutical agent that can be used to treat such diseases as cancer and hepatitis, it has been learned. The procedure uses genome editing technology to produce interferon beta, a type of protein related to the immune system, at a relatively low cost. As early as next year, a joint research company plans to sell the drug as a research reagent at a price about half that of the conventional product. Eventually, they hope to lower the price to less than 10 percent of the current level. Interferon beta is used in the treatment of malignant skin cancer and hepatitis, as well as for virus research. Conventional product...

Tropical Storm Nate has killed at least 22 people in Central America as it pummeled the region with heavy rain while heading toward Mexico's Caribbean resorts and the US Gulf Coast, where it could strike as a hurricane this weekend. In Nicaragua, at least 11 people died on Thursday, seven others were reported missing and thousands had to evacuate homes because of flooding, said the country's vice president Rosario Murillo. Emergency officials in Costa Rica reported that at least eight people were killed due to the lashing rain, including two children. Another 17 people were missing, while more than 7000 had to take refuge from Nate in shelters, authorities said. Two youths also drowned in Honduras due to the sudden swell in a river, while a man was killed in a mud slide
TRABUCO HILLS (CBSLA.com) — State and federal agencies are looking into a disturbing incident in which a teacher might have distributed handmade flutes tainted with the man’s bodily fluids to school districts across Orange County. The California Department of Justice and the United States Postal Service are investigating a yet unnamed music instructor for giving flutes that might contain bodily fluids to several school districts in Southern California, including the Fountain Valley, Capistrano, and Newport Mesa agencies http://losangeles.cbslocal.com/2017/09/29/teacher-flutes-tainted-with-bodily-fluids/

Microparticles created by new 3D fabrication method could release drugs or vaccines long after injection. MIT engineers have invented a new 3-D fabrication method that can generate a novel type of drug-carrying particle that could allow multiple doses of a drug or vaccine to be delivered over an extended time period with just one injection. The new microparticles resemble tiny coffee cups that can be filled with a drug or vaccine and then sealed with a lid. The particles are made of a biocompatible, FDA-approved polymer that can be designed to degrade at specific times, spilling out the contents of the “cup.” “We are very excited about this work because, for the first time, we can create a library of tiny, encased vaccine particles, each programmed to release at a precise, predictab
Opioid use by American men may account for one-fifth of the decline in their participation in the U.S. labor force, according to a study by Princeton University economist Alan Krueger. “The opioid crisis and depressed labor-force participation are now intertwined in many parts of the U.S.,” Krueger, who was chief economist at the Treasury Department in the Obama administration, wrote in the study released Thursday at a Brookings Institution conference in Washington. Krueger’s study linked county prescription rates to labor force data from the past 15 years, concluding that regional differences in prescription rates were due to variations in medical practices, not health conditions. In previous research, he found that nearly half of men in their prime worker ag
Monsanto Company and ToolGen, Inc., a biotechnology company specializing in genome editing, announced today that the companies have reached a global licensing agreement for the use of ToolGen’s CRISPR technology platform to develop agricultural products. ToolGen is an early pioneer in gene editing research. The license provides Monsanto with access to ToolGen’s comprehensive suite of CRISPR intellectual property for use in plants. This agreement further expands Monsanto’s broad portfolio of gene-editing tools that can be used to develop improved and sustainable crops. “We are excited to bring ToolGen’s CRISPR platform on board at Monsanto, and are continuing to bolster and diversify our capabilities in this field of research,” said Tom Adams, Ph.D., vice president of biotechnology fo
Officials in two Arizona counties are warning the public after fleas in the region tested positive for the plague, the infamous infectious disease that killed millions during the Middle Ages. Navajo County Public Health officials confirmed on Friday that fleas in the area have tested positive for the rare disease. The public health warning follows a similar notice from Coconino County Public Health Services District in Arizona warning of the presence of plague in fleas found there too. Both counties are situated in the northern part of Arizona. "Navajo County Health Department is urging the public to take precautions to reduce their risk of exposure to this serious disease, which can be present in fleas, rodents, rabbits and predators that feed upon these animals," the public heal...

Scientists have hailed a “breakthrough” technology capable of regrowing damaged organs and healing serious wounds with the single touch of a penny-sized pad. The new device uses nanochips to reprogramme skin cells which then generate any type of cell necessary for medical treatment. The non-invasive procedure takes less than a second and in laboratory trials was found to restore the function of badly damaged blood vessels within days. Dubbed tissue nanotransfection (TNT), the technique works by placing a small pad of nanochips over a damaged area. A small electric current then fires DNA into the skin cells, converting them into the specific building block cells of any other part of the body, such as arteries, or even organs like the heart. It promises to transform the
