Silence is golden -- Suppressing host response to Ebola virus may help to control infection

EurekAlert! - Mar, 03/21/2017 - 22:00
The Ebola virus causes a severe, often fatal illness when it infects the human body. Initially targeting cells of the immune system called macrophages, white blood cells that absorb and clear away pathogens, a new study has found a way to potentially 'silence' these Ebola virus-infected macrophages.The findings, which appear in the Journal of Virology, could lead to new treatment options for Ebola virus disease.

Diametric brain circuits switch feeding and drinking behaviors on and off in mice

NSF-funded IUPUI study of non-rainfall water in Namib Desert reveals unexpected origins

EurekAlert! - Mar, 03/21/2017 - 22:00
In a study conducted in one of the world's oldest and most biologically diverse deserts, Indiana University-Purdue University Indianapolis scientists explore the origins of water other than rainfall and are identifying multiple origins. The study, supported by the National Science Foundation, is the first to report that the ocean is not the sole source of life-sustaining fog and dew for numerous plants and animals living in the Namib Desert.

Using a smartphone to screen for male infertility

EurekAlert! - Mar, 03/21/2017 - 22:00
Investigators at Brigham and Women's Hospital set out to develop a home-based diagnostic test that could be used to measure semen quality using a smartphone-based device. New findings by the team indicating that the smartphone-based semen analyzer can identify abnormal semen samples based on sperm concentration and motility criteria with approximately 98 percent accuracy are published online on March 22 in Science Translational Medicine.

Brain 'rewires' itself to enhance other senses in blind people

EurekAlert! - Mar, 03/21/2017 - 22:00
The brains of those who are born blind make new connections in the absence of visual information, resulting in enhanced, compensatory abilities such as a heightened sense of hearing, smell and touch, as well as cognitive functions (such as memory and language) according to a new study led by Massachusetts Eye and Ear researchers.

Huns and settlers may have cooperated on the frontier of Roman Empire

EurekAlert! - Mar, 03/21/2017 - 22:00
Analysis of isotopes in bones and teeth from fifth-century cemeteries suggests that nomadic Huns and Pannonian settlers on the frontier of Roman Empire may have intermixed, according to a study published March 22, 2017 in the open-access journal PLOS ONE by Susanne Hakenbeck from University of Cambridge, United Kingdom, and colleagues.

Nature conservation as a bridge to peace in the Middle East

EurekAlert! - Mar, 03/21/2017 - 22:00
Loss of biodiversity is a major challenge in today's world as is the quest for peace in regions engaged in conflict. But scientists writing in a Review published March 22 in Trends in Ecology & Evolution say that efforts to conserve natural resources present an opportunity to find common ground between communities at odds, building trust and renewed hope for peace.

Researchers create self-sustaining bacteria-fueled power cell

EurekAlert! - Mar, 03/21/2017 - 22:00
Instead of oil, coal, or even solar energy, self-sustaining bacterial fuel cells may power the future.Researchers at Binghamton University, State University of New York have developed the next step in microbial fuel cells (MFCs) with the first micro-scale self-sustaining cell, which generated power for 13 straight days through symbiotic interactions of two types of bacteria.

Metabolites of Resveratrol (Longevinex) pass through blood-ocular barriers in humans

EurekAlert! - Mar, 03/21/2017 - 22:00
On the heels of a study published last year that showed the red wine molecule resveratrol and its metabolites are found in human cerebrospinal fluid and therefore penetrate the blood-brain barrier, for the first time metabolites of the red wine molecule resveratrol have been detected in ocular tissues of humans as well. [Neurology Oct 2015; Journal Ophthalmology March 20, 2017]

AMP issues best practice guidelines for next-generation sequencing-based oncology panel validation

EurekAlert! - Mar, 03/21/2017 - 22:00
AMP has published consensus recommendations that will help clinical laboratory professionals achieve high-quality sequencing results and deliver better care for cancer patients

'Super sponge' promises effective toxic clean-up of lakes and more

EurekAlert! - Mar, 03/21/2017 - 22:00
Mercury is very toxic and can cause long-term health damage, but removing it from water is challenging. To address this growing problem, University of Minnesota College of Food, Agricultural and Natural Sciences (CFANS) Professor Abdennour Abbas and his lab team created a sponge that can absorb mercury from a polluted water source within seconds.

Hospital or home? Guidelines to assess older people who have fallen

EurekAlert! - Mar, 03/21/2017 - 22:00
Guidelines to help paramedics make the right decision for older people who have fallen are safe, cost-effective and help reduce further 999 calls, according to new research led by a team at Swansea University Medical School.

Method speeds testing of new networking protocols

EurekAlert! - Mar, 03/21/2017 - 22:00
At the Usenix Symposium on Networked Systems Design and Implementation later this month, researchers from MIT's Computer Science and Artificial Intelligence Laboratory will present a system for testing new traffic management protocols that requires no alteration to network hardware but still works at realistic speeds -- 20 times as fast as networks of software-controlled routers.

Research evaluates treatment of thyroid disease in pregnancy

EurekAlert! - Mar, 03/21/2017 - 22:00
New research indicates that universal screening for and subsequent treatment of subclinical hypothyroidism does not result in improved health outcomes for mothers or babies. The research was conducted through the Eunice Kennedy Shriver National Institute of Child Health and Human Development Maternal-Fetal Medicine Units (MFMU) Network and has been published this month in the New England Journal of Medicine.

Fledgling stars try to prevent their neighbors from birthing planets

EurekAlert! - Mar, 03/21/2017 - 22:00
Stars don't have to be massive to evaporate material from around nearby stars and affect their ability to form planets, a new study suggests.

Streamlined analysis could help people better manage their emotions

EurekAlert! - Mar, 03/21/2017 - 22:00
The strategies people use to manage their emotions fall into three core groupings, according to newly published research from the University at Buffalo. Since a lot of psychopathology is related to difficulty in regulating emotions, the findings may benefit researchers and clinicians trying to better understand and treat a range of psychological disorders, everything from anxiety to substance abuse, by streamlining assessment and giving people the tools necessary to more constructively work with their emotions.

Surveiling the consumer for loyalty and profit

EurekAlert! - Mar, 03/21/2017 - 22:00
Surveillance may be a dirty word when it comes to domestic politics, but understanding what interests the consumer and how technology may provide insights is a legitimate concern of retailers. Exactly which technologies yield the appropriate balance of potential profits and privacy can be a confounding dilemma. Marketing Professors J. Jeffrey Inman and Hristina Nikolova reviewed recent retail technologies and created a guide to help retailers find their way through.
