New discoveries predict ability to forecast dementia from single molecule

EurekAlert! - Lun, 12/10/2018 - 23:00
Scientists who recently identified the molecular start of Alzheimer's disease have used that finding to determine that it should be possible to forecast which type of dementia will develop over time -- a form of personalized medicine for neurodegenerative diseases.

Internet therapy apps reduce depression symptoms, IU study finds

EurekAlert! - Lun, 12/10/2018 - 23:00
In a sweeping new study, Indiana University psychologists have found that a series of self-guided, internet-based therapy platforms effectively reduce depression. The work, which reviewed 21 pre-existing studies with a total of 4,781 participants, was published in the November issue of the Journal of Medical Internet Research. The study was led by Lorenzo Lorenzo-Luaces, a clinical professor in the IU Bloomington College of Arts and Sciences' Department of Psychological and Brain Sciences.

CCNY-Yale researchers make shape shifting cell breakthrough

EurekAlert! - Lun, 12/10/2018 - 23:00
A new computational model developed by researchers from The City College of New York and Yale gives a clearer picture of the structure and mechanics of soft, shape-changing cells that could provide a better understanding of cancerous tumor growth, wound healing, and embryonic development.

Alaska earthquakes offer new insight into improving hazard assessment

EurekAlert! - Lun, 12/10/2018 - 23:00
Earthquake hazard assessment often overlooks intra-slab earthquakes. EarthScope Transportable Array data for the 2016 Iniskin and Nov. 30, 2018 Anchorage earthquakes in Alaska offer new insight into potential causes of heavy shaking from these intra-slab events.

Drug repositioning strategy identifies potential anti-epilepsy drugs

EurekAlert! - Lun, 12/10/2018 - 23:00
Starting with human brain tissue from patients with epilepsy, University of Iowa researchers used gene expression profiling and bioinformatics to identify 91 FDA-approved drugs, that may also have potential as anti-epilepsy treatments. Testing showed three of drugs -- a diabetes drug, a hypertension medication, and an antiparasitic therapy -- significantly reduced seizure-like movement in zebrafish.

Stronger pesticide regulations likely needed to protect all bee species, say studies

EurekAlert! - Lun, 12/10/2018 - 23:00
Regulators worldwide currently use honeybees as the sole model species failing to account for potential threats posed by agrochemicals to the full diversity of bee species from bumblebees to solitary bees, which are probably more important for pollination of food crops than managed honeybees. They are potentially more vulnerable to pesticides given they nest in the ground and bumblebee queens have different life cycles that could increase exposure.

Brigham researchers develop smartphone-based ovulation test

EurekAlert! - Lun, 12/10/2018 - 23:00
Artificial intelligence used to detect signs of ovulation in a woman's saliva automatically and at low cost.

A future for red wolves may be found on Galveston Island

EurekAlert! - Lun, 12/10/2018 - 23:00
Red wolves, once nearly extinct, again teeter on the abyss. New research finds red wolf ancestry in Texas -- providing opportunities for additional conservation action and difficult policy challenges. Michigan Tech researcher Kristin Brzeski and others have identified red wolf "ghost alleles" in canid population on Galveston Island.

Gut microbiome may affect some anti-diabetes drugs

EurekAlert! - Lun, 12/10/2018 - 23:00
Why do orally-administered drugs for diabetes work for some people but not others?According to researchers at Wake Forest School of Medicine, bacteria that make up the gut microbiome may be the culprit.

Women and men with heart attack symptoms get different treatment from EMS

EurekAlert! - Lun, 12/10/2018 - 23:00
Researchers from the George Washington University (GW) have examined the care that women and men with heart attack symptoms receive from emergency medical services (EMS) after a 911 call and found that women were less likely to receive aspirin, be resuscitated, or be transported to the hospital in ambulances using lights and sirens.

Superhero science: Ant-Man and the Wasp

EurekAlert! - Lun, 12/10/2018 - 23:00
For most of Mikel-Stites' life, he had been nit-picking at the 'science' in science-fiction movies.

National Institute for Health and Care Excellence (NICE) issues new guidelines for COPD

EurekAlert! - Lun, 12/10/2018 - 23:00
NICE makes a 'strong' recommendation that patients with severe COPD be referred for evaluation for bronchoscopic lung volume reduction, including the Zephyr® Endobronchial Valve System.NICE has broadened the criteria for evaluation and a new group of people for whom lung volume reduction surgery was unsuitable may now be evaluated for treatment with Zephyr Valves, a less invasive treatment option.

Macrophage cells key to helping heart repair -- and potentially regenerate: New study

EurekAlert! - Lun, 12/10/2018 - 23:00
Macrophage cells have the ability to act in a neo-natal-like state, a time in life where they aid in the growth and development of organs, meaning they could be channeled to help repair the heart following a heart attack.

FEFU young scientists developed unique method to calculate transparent materials porosity

EurekAlert! - Lun, 12/10/2018 - 23:00
Applying the new method, technologists and materials scientists will be able to quickly, accurately and without destroying the studied objects to obtain information about the microstructure and functionality of transparent materials - single crystals, glasses, and ceramics. The article on that is available online on the site of the Journal of Alloys and Compounds.

Relationship impairments hinder men seeking mental health treatment

EurekAlert! - Lun, 12/10/2018 - 23:00
Relationship impairment (difficulty managing expectations and requirements within an intimate relationship) plays a role in explaining the association between symptom severity and those seeking treatment among post-9/11 military veterans. However, the role it plays is different for men and women.

Better biomedical devices, wearable displays may result from tiny light-guiding structures

EurekAlert! - Lun, 12/10/2018 - 23:00
For the first time, researchers have fabricated light-guiding structures known as waveguides just over one micron wide in a clear silicone commonly used for biomedical applications. The tiny, flexible waveguides can be used to make light-based devices such as biomedical sensors and endoscopes that are smaller and more complex than currently possible.

Possible connection between cardiovascular disease and living near oil and gas wells

EurekAlert! - Lun, 12/10/2018 - 23:00
Researchers at the Colorado School of Public Health have found a possible connection between the intensity of oil and gas exploration in an area and early indicators of cardiovascular disease among nearby residents.

Terahertz laser for sensing and imaging outperforms its predecessors

EurekAlert! - Lun, 12/10/2018 - 23:00
A terahertz laser designed by MIT researchers is the first to reach three key performance goals at once -- high constant power, tight beam pattern, and broad electric frequency tuning -- and could thus be valuable for a wide range of applications in chemical sensing and imaging.

BMI is a good measure of health after all, new study finds

EurekAlert! - Lun, 12/10/2018 - 23:00
A new study from the University of Bristol supports body mass index as a useful tool for assessing obesity and health.

NASA measures rainfall from Tropical Cyclone Owen's remnants at Queensland coast

EurekAlert! - Lun, 12/10/2018 - 23:00
The low pressure area formerly known as Tropical Cyclone Owen continued to organize and cross the southern Gulf of Carpentaria, Australia on Dec. 11. The Global Precipitation Measurement mission or GPM core satellite provided a look at the rainfall rates within the system.
