In a bid to detect cancers early and in a noninvasive way, scientists at the Johns Hopkins Kimmel Cancer Center report they have developed a test that spots tiny amounts of cancer-specific DNA in blood and have used it to accurately identify more than half of 138 people with relatively early-stage colorectal, breast, lung and ovarian cancers. The test, the scientists say, is novel in that it can distinguish between DNA shed from tumors and other altered DNA that can be mistaken for cancer biomarkers.

  In the face of opposition by the power industry, Environmental Protection Agency chief Scott Pruitt is planning to scrap an Obama-era rule to curb discharges of lead, arsenic and mercury from power plants into sources of drinking water. The Environme…

Get your maps. Some public lands are remote areas along unmaintained roads and are often inter-mingled with private land, so know where you're going. Contact your local Bureau of Land Management, National Park Service, US Fish and Wildlife Service, or Forest Service offices for camping and jurisdiction maps. Before you head out, make sure you are familiar with the area you are going to and ensure you have appropriate gear, equipment, and supplies.

Health and Human Services Secretary Tom Price and other top Trump appointees are outspoken opponents of federal funding for birth control, advocating abstinence rather than contraceptives to control teen pregnancies. Among the programs that lost their funding: the Choctaw Nation’s efforts to combat teen pregnancy in Oklahoma, Johns Hopkins’ work with adolescent Apaches in Arizona, the University of Texas’ guidance for youth in foster care, the Chicago Department of Public Health’s counseling and testing for sexually transmitted infections and the University of Southern California’s workshops for teaching parents how to talk to middle school kids about delaying sexual activity.

Jo Freeman writes: Unlike the other social sciences, psychology is thriving. While the supply of trained psychologists in the labor force has remained constant since 2005, the demand has grown. Quite a few employers purchased booths in the exhibit area just to advertising that they were hiring and interview potential recruits. They ranged from clinics in Hattiesburg, MS to New Zealand.

Internet Scout's Research Group's weekly marvelous discoveries: In February 1623, a group of Dutch officials accused a team of English merchants and Japanese mercenaries of conspiring to capture a castle on Amboyna, a small island in what is now part of Indonesia. The island was central to the booming spice trade, which had fueled an increasingly acrimonious rivalry between the British and the Dutch. "Folk art is a reflection of society as seen through the eyes of artists whose perceptions are sometimes traditional and conventional - sometimes unruly, and even wild." So writes the Canadian Museum of History, host of a online exhibit that highlights Quebec folk art from the eighteenth century through today. Michael Twitty explains how enslaved African-Americans created contemporary American southern cuisine.

About 10.3 million people have health insurance that they purchased through the ACA exchanges or marketplaces, where people who don’t get insurance through their employer can shop for insurance and compare prices and benefits. Seven in ten (69 percent) say it is more important for President Trump and Republicans' next steps on health care to include fixing the remaining problems with the ACA in order to help the marketplaces work better, compared to three in ten (29 percent) who say it is more important for them to continue plans to repeal and replace the ACA.

Murder Is Her Hobby: Frances Glessner Lee and The Nutshell Studies of Unexplained Death explores the surprising intersection between craft and forensic science. Frances Glessner Lee (1878 1962) crafted her extraordinary Nutshell Studies of Unexplained Death exquisitely detailed miniature crime scenes to train homicide investigators to "convict the guilty, clear the innocent, and find the truth in a nutshell." These dollhouse-sized diorama composites of true crime scenes helped revolutionize forensic science.

UC Berkeley solar physicist Oliveros cautions that smart phones, cameras, binoculars or telescopes must also be protected by an eclipse filter, created either by cutting up eclipse glasses and taping the filter over the camera lens, or by buying a special sun-safe filter or a number 14 welder’s glass to mount over the objective lens. 

Discovery's three-part documentary, First in Human, which follows the experiences of patients, their families, doctors, researchers, staff, and caregivers at the NIH Clinical Center, will air on three sequential Thursday evenings: August 10, 17, and 24, at 9:00 p.m. ET/PT. To further educate the public about clinical research and the NIH, we are planning social media events around the three episodes. We invite you to join us in any of these events using #FirstinHuman:

More than half of Americans now regularly take a prescription medication — four drugs, on average. 53% of those who take prescription drugs get them from more than one healthcare provider, which increases the risk of adverse drug effects. 35% percent of those taking prescription drugs say a healthcare provider has never reviewed their medicine to see if they can stop any of them. Almost 1.3 million went to US emergency rooms due to adverse drug effects in 2014, and about 124,000 died from those events, according to estimates based on data from the Centers for Disease Control and Prevention and the Food and Drug Administration.

This bill [Seniors Fraud Prevention Act of 2017] directs the Federal Trade Commission (FTC) to establish an office within the Bureau of Consumer Protection to advise the FTC on the prevention of fraud targeting seniors and to assist the FTC in monitoring the market for mail, television, Internet, telemarketing, and recorded message telephone call (robocall) fraud targeting seniors. The office must: (1) disseminate to seniors and their families and caregivers information on the most common fraud schemes, including methods of reporting complaints either to the FTC's national toll-free telephone number or to the FTC's Consumer Sentinel Network, (2) provide, in response to a specific request about a particular entity or individual, publicly available information regarding the FTC's enforcement action; and (3) maintain a website as a resource for information on fraud targeting seniors.

Ferida Wolff writes: When nature changes, it's not only the geese that must adapt. Temperatures are rising. The ocean is heating up and heading inland, threatening some shore communities and islands. Some areas are becoming parched and fires are more common and difficult to control. Extreme weather patterns are cropping up. Can we change our habits to help minimize the effect of global climate change? Can we recognize the importance of our behavior on nature? Will we need to be as adaptable as Canadian geese?

The pharmacological effect is so powerful that it can activate a chain of events that can result in addiction. The main cause of opioid death is when the drug binds to the receptors in the brain stem that control breathing. When the drug manipulates that area it triggers respiratory depression, and an individual can stop breathing.
