Study reveals surprises concerning COPD and smoking

EurekAlert! - Mar, 03/21/2017 - 22:00
A new study challenges the widely accepted but oversimplified description of airway inflammation in smokers and patients with chronic obstructive pulmonary disease (COPD).

Does boosting 'good' cholesterol really improve your health?

EurekAlert! - Mar, 03/21/2017 - 22:00
A new review addresses the mysteries behind 'good' HDL cholesterol and why boosting its levels does not necessarily provide protection from cardiovascular risk for patients. It appears that augmenting the function of HDL cholesterol, rather than its concentration, is key.

Some blood thinners may increase heart attack risk

EurekAlert! - Mar, 03/21/2017 - 22:00
A new study has examined whether different blood thinning medications prescribed to prevent strokes in patients with atrial fibrillation might increase the risk of heart attacks.

Many adults have insufficient knowledge about heart failure

EurekAlert! - Mar, 03/21/2017 - 22:00
In the largest German survey on heart failure to date, investigators found that the overall awareness of heart failure has not increased over the past decade and is not at a satisfactory level.

Loss of smell linked to increased risk of early death

EurekAlert! - Mar, 03/21/2017 - 22:00
In a study of adults aged 40 to 90 years who were followed for 10 years, poor smell was linked with an increased risk of dying.

How reliable are traditional wildlife surveys?

EurekAlert! - Mar, 03/21/2017 - 22:00
To effectively manage a wildlife species, one of the most basic things you need to know is how many of them are out there. However, it's almost never feasible to count every single individual -- so how do the results of wildlife surveys compare to true population size? A new study in The Condor: Ornithological Applications tests this using the results of more than thirty years of surveys of the Rocky Mountain population of sandhill cranes.

Endangered ibises benefit from joining egret flocks

EurekAlert! - Mar, 03/21/2017 - 22:00
Birds benefit from flocking together -- even when they're not of a feather. According to a new study in The Auk: Ornithological Advances, China's endangered crested ibises benefit from joining forces with other, more visually-oriented bird species while searching for food.

Non-invasive prostate cancer diagnosing, monitoring

EurekAlert! - Lun, 03/20/2017 - 22:00
Technology being developed at Washington State University provides a non-invasive approach for diagnosing prostate cancer and tracking the disease's progression. It could enable doctors to determine how cancer patients are responding to different treatments without needing to perform invasive biopsies.

Optical tool monitors brain's circulatory response to pain

EurekAlert! - Lun, 03/20/2017 - 22:00
A study reported today in the journal Neurophotonics demonstrates that an optical imaging tool used to monitor regional blood flow and tissue oxygenation may be used to track the brain's response to acute pain in infants, children, and adults. The journal is published by SPIE, the international society for optics and photonics.

Scientists follow seeds to solve ecological puzzle

EurekAlert! - Lun, 03/20/2017 - 22:00
A four-year study of one rare and one common lupine growing in coastal dunes showed that a native mouse steals most of the rare lupines seeds while they are still attached to the plant. The mouse is a 'subsidized species,' given cover for nocturnal forays by European beachgrass, originally planted to stabilize the dunes.

Weekend surgery has no impact on death risk, study shows

EurekAlert! - Lun, 03/20/2017 - 22:00
Day of the week did not affect the survival chances of people undergoing emergency surgery, research in Scotland has found. The findings from the University of Edinburgh challenge the results of previous studies, which had suggested that those who undergo elective surgery at the end of the week are at a greater risk of dying.

430 million-year-old fossil named in honor of Sir David Attenborough

An international team of scientists led by the University of Leicester has discovered a new 430 million-year-old fossil and has named it in honor of Sir David Attenborough -- who grew up on the University campus.

Universe's ultraviolet background could provide clues about missing galaxies

EurekAlert! - Lun, 03/20/2017 - 22:00
Astronomers have developed a way to detect the ultraviolet background of the universe, which could help explain why there are so few small galaxies in the cosmos.
