After evaluating content on idiopathic pulmonary fibrosis on almost 200 websites, researchers found that the information on Idiopathic Pulmonary Fibrosis
(IPF) from these sites was often incomplete, inaccurate and outdated. 

Political journalists will file countless reports from Iowa in the final days leading up to the caucuses, much of based on polls.

Another poll, this one by the Iowa State University/WHO-HD Iowa Caucus Poll, finds that voters rely on a variety of these reports and national television news still leads. 

Imagine communicating with your bank, the IRS or your doctor by way of an Internet that was actually secure, where if any bad actor were to try to eavesdrop you would know immediately. Such is the promise of secure quantum communication, and has been since it was 'almost ready' starting in the 1990s.

For quantum communication to become the standard, technical challenges still lie ahead. To make progress toward devices that can send and receive quantum data, researchers at Stanford University have created a novel quantum light source. 

Scarring is a natural part of any healing process but scar formation within blood vessels can be deadly.

To prevent scarring and the dangerous damage that follows, researchers writing in ACS Biomaterials Science and Engineering discuss development of a new biodegradable material with built-in vitamin A, which has been shown to reduce scarring in blood vessels. This soft elastic material can be used to treat injured vessels or be used to make medical devices, such as stents and prosthetic vascular grafts, to give them intrinsic healing properties. Early tests have shown that the material can reduce cell migration -- a major contributor to the scarring process -- by 57 percent.

It’s a common assumption that being online means you’ll have to part ways with your personal data and there’s nothing you can do about it.

How do you know the paper claiming GMO toxicity is in a journal that isn't very reputable? They don't have $9 to renew their domain.
Surgeons removing a malignant brain tumor don’t want to leave cancerous material behind, but they also need to protect healthy brain matter and minimize neurological harm. Once the patient’s skull is open, there’s no time to send tissue samples to a pathology lab to be frozen, sliced, stained, mounted on slides and investigated under a bulky microscope in order distinguish between cancerous and normal brain cells.

A handheld, miniature microscope could allow surgeons to “see” at a cellular level in the operating room and determine where to stop cutting. The researchers hope that after testing the microscope’s performance as a cancer- screening tool, it can be introduced into surgeries or other clinical procedures within the next 2 to 4 years.

A small pilot study in the Journal of Medical Internet Research finds that using smartphone reminders to prompt people to get moving may help reduce sedentary behavior.

Prior papers have corrolated sedentary time to increased risk of breast, colorectal, ovarian, endometrial, and prostate cancers as well as weight gain, higher BMI, and obesity. Still, we love our phones. Surveys finds that adults in the U.S. report spending an average of about 8 waking hours per day being sedentary. 

A new method to determine if bacteria are susceptible to antibiotics within a few hours could slow the appearance of drug resistance and allow doctors to more rapidly identify the appropriate treatment for patients with life threatening bacterial infections.

According to the Centers for Disease Control and Prevention, antibiotic resistance causes two million illnesses and 23,000 deaths annually, costing the U.S. economy approximately $20-billion a year in direct health care costs and nearly eight million extra days in the hospital. Indeed, bacteria are evolving resistance to antibiotics much more quickly than global biomedical research efforts are delivering new drugs to market, leading to the appearance of infections caused by bacteria that are now resistant to every therapy.

Heartbeats can now be measured without placing sensors on the body, thanks to a new way to measure heartbeats remotely, in real time, and under controlled conditions with as much accuracy as electrocardiographs.

The researchers say this will allow for the development of "casual sensing" -- taking measurements as people go about their daily activities, for instance, when they are going to bed or getting ready to start the day. Kind of like a Fitbit, except accurate

"Taking measurements with sensors on the body can be stressful and troublesome, because you have to stop what you're doing," says Hiroyuki Sakai, a researcher at Panasonic. "What we tried to make was something that would offer people a way to monitor their body in a casual and relaxed environment."
