Informed consent: False positives not a worry in lung cancer study

A new study of participants in the National Lung Screening Trial finds that a false positive screen result — a screening test in which initial findings of concern for cancer are later found not to be worrisome — did not cause participants undue anxiety or reduced quality of life. Researchers hypothesize that clear and accurate consent forms prepared patients for these false positive diagnoses.

Tropical Storm Genevieve forms in Eastern Pacific

The seventh tropical depression of the Eastern Pacific Ocean formed and quickly ramped up to a tropical storm named ‘Genevieve.’ The National Oceanic and Atmospheric Administration’s GOES-West satellite captured an infrared image of the newborn storm being trailed by two other areas of developing low pressure to its east.

Test increases odds of correct surgery for thyroid cancer patients

The routine use of a molecular testing panel increases the likelihood of performing the correct initial surgery for thyroid cancer patients by 30 percent, the University of Pittsburgh Cancer Institute, partner with University of Pittsburgh Medical Center CancerCenter, reports in the Annals of Surgery. The test is available at the University of Pittsburgh Medical Center/University of Pittsburgh Cancer Institute Multidisciplinary Thyroid Center and other diagnostic testing agencies.

Manipulating key protein in the brain holds potential against obesity and diabetes

A protein that controls when genes are switched on or off plays a key role in specific areas of the brain to regulate metabolism, UT Southwestern Medical Center researchers have found. The research potentially could lead to new therapies to treat obesity and diabetes, since the transcription factor involved – spliced X-box binding protein 1 – appears to influence the body’s sensitivity to insulin and leptin signaling.

Washington State’s Sprawling Wildfire Captured By Drone Cam

Washington State's Sprawling Wildfire Captured By Drone CamThe sky is thick with smoke in central Washington, as the state's largest wildfire in recorded history leaves a charred trail of burned homes and blackened trees. The Carlton Complex Fire began as four separate fires that were triggered by lightning on July 14. As of today (July 24), the fire is spread over 390 square miles (1,010 square kilometers), or about one-third the size of Rhode Island, said Paul Gibbs, a spokesman for the fire crews battling the wildfire. Video production company Chelan HD sent out a drone to record aerial footage of the burned landscape.

DIY Vaginal Ultrasounds Could Reduce Trips to the Doctor

DIY Vaginal Ultrasounds Could Reduce Trips to the DoctorThe technology allows these women to perform vaginal ultrasounds at home, while their doctor views the results from afar. They are given a vaginal ultrasound (in which an ultrasound probe is placed into the vagina) to view the ovaries, so the doctor can see whether the eggs are maturing. In the study, 123 women in Belgium who were undergoing IVF were randomly assigned to either home monitoring, or the regular trips to the doctor's office. They were shown how to use the probe to take video recordings of their ovaries, and how to upload and send the videos to their doctor.

Truth Be Told, White Lies Can Keep Relationships Strong

The model showed that individuals who tell anti-social lies become isolated from others within their social networks over time. In fact, these individuals tend to form strong links with other individuals within their social networks. Social networks that people create online — on sites such as Facebook and Twitter — mimic the social networks they’re part of in the real world. Yes, they do, said Larry Rosen, a psychology professor at California State University, Dominguez Hills.

Bayer says Nexavar fails in breast cancer study

The logo of Germany's largest drugmaker Bayer is pictured in LeverkusenFRANKFURT (Reuters) – German drugmaker Bayer said a Phase III trial of cancer drug Nexavar in patients with advanced breast cancer did not meet its primary endpoint of delaying the progression of the disease. The study, called Resilience, evaluated Nexavar in combination with chemotherapeutic agent capecitabine, in women with HER2-negative breast cancer. Oral drug Nexavar, which Bayer is developing jointly with Amgen, is approved for use against certain types of liver, kidney and thyroid cancer. Study details are expected to be presented at an upcoming scientific conference. …

See the Moon, Mercury and Venus Before Sunrise Friday

See the Moon, Mercury and Venus Before Sunrise FridayMercury and Venus will star in an early morning meet-up with the moon Friday (July 24). Both planets can be seen low in the east-northeast roughly 45 minutes before sunrise. Mercury appears only about one twelfth as bright as Venus, and yet shining at magnitude -1 it ranks second only to Sirius in terms of brightness. To enhance your chances of seeing Mercury, the moon and Venus, try scanning the east-northeast horizon with binoculars.

Astronauts Simulate Deep-Space Mission in Underwater Lab

Astronauts Simulate Deep-Space Mission in Underwater LabPlenty of astronauts practice spacewalks in the water, but a crew currently living in an underwater lab plans to introduce a surprising twist to its aquatic excursions: They will create a 10-minute communications delay with Mission Control, simulating what speaking with people on Earth could be like in deep space. The four astronauts participating in the nine-day NASA Extreme Environment Mission Operations (NEEMO) 18 mission will perform underwater "spacewalks" in which they pretend to be on an asteroid far from Earth, where radio communications between the two locales would take minutes, not seconds, as communication from the International Space Station does. By then, Mission Control can give astronauts instructions on which spots to sample, crew members said during a news conference Wednesday (July 23). "We'll be testing out those tools if we did go to an asteroid," said Jeanette Epps, a NASA astronaut who is part of the NEEMO 18 crew.

Scientists to excavate Wyoming cave with trove of Ice Age fossils

Scientists will begin excavation early next week of an ancient Wyoming sinkhole containing a rare bounty of fossil remains of prehistoric animals, such as mammoths and dire wolves, preserved in unusually good condition, researchers said on Thursday.    The two-week dig, set to begin next Monday under the direction of Des Moines University paleontologist Julie Meachen, marks the first exploration of Natural Trap Cave in north-central Wyoming since its initial discovery in the 1970s.

Keryx drug improves phosphorus, iron in kidney patients: trial

(Reuters) – A pivotal trial of Keryx Biopharmaceuticals Inc’s experimental drug Zerenex showed that it improved levels of serum phosphorus and iron in patients on kidney dialysis, according to results published on Thursday. The trial involved 441 patients, according to the Journal of the American Society of Nephrology, which published the results. Over the four-week efficacy assessment period, mean serum phosphorus for Zerenex patients dropped by 2.2 milligrams per deciliter compared with placebo patients, the trial showed. Most patients with kidney disease that requires dialysis need chronic treatment with phosphate-binding agents to lower and maintain serum phosphorus at acceptable levels.

Researchers practice living on Mars – without leaving Earth

For the most part, expedition leader Casey Stedman and his five crewmates have stayed inside their 1,000-square foot (93-square meter) solar-powered dome, venturing out only for simulated spacewalks and doing so only when fully attired in mock spacesuits. “I haven’t seen a tree, smelled the rain, heard a bird, or felt wind on my skin in four months,” Stedman wrote in a blog on Instagram. Stedman is a U.S. Air Force Reserve officer, graduate student at Embry-Riddle Aeronautical University Worldwide. “We are simulating a long-duration mission on Mars, with a focus on crew psychology in isolation,” the crew said during an online interview with Reddit on Sunday.
