Rare mutation of gene carried by Quebec family gives insight into how the brain is wired

EurekAlert! - Dom, 06/17/2018 - 22:00
The study of a Quebec family with an unusual gene provides novel insight into how our brain is built and, according to the McGill-led team of scientists, offers a better understanding of psychiatric disorders such as depression, addictions and schizophrenia.

Daily fasting works for weight loss

EurekAlert! - Dom, 06/17/2018 - 22:00
A new study shows that daily fasting is an effective tool to reduce weight and lower blood pressure. The study is the first to examine the effect of time-restricted eating on weight loss in obese individuals.

Hunting molecules to find new planets

EurekAlert! - Dom, 06/17/2018 - 22:00
It's impossible to obtain images of an exoplanet, so dazzling is the light of its star. However, astronomers led by UNIGE have the idea of detecting molecules that are present in the planet's atmosphere in order to make it visible, provided that these same molecules are absent from its star. Thanks to this innovative technique, the device is sensitive to the selected molecules, making the star invisible and allowing the astronomers to observe the planet.

New study suggests ovarian hormone may make drug withdrawal symptoms worse for women

EurekAlert! - Dom, 06/17/2018 - 22:00
Researchers found that a form of the estrogen hormone can contribute to drug relapse in females by worsening withdrawal symptoms. The study looked at the interaction of the female sex hormone estradiol and methamphetamine.

Cementless fly ash binder makes concrete 'green'

EurekAlert! - Dom, 06/17/2018 - 22:00
Rice University engineers have developed a composite binder made primarily of fly ash, a byproduct of coal-fired power plants, that can replace Portland cement in concrete.

Rewiring plant defence genes to reduce crop waste

EurekAlert! - Dom, 06/17/2018 - 22:00
Plants could be genetically rewired to better resist disease, helping safeguard crop yields worldwide according to new research by the universities of Warwick and York. Defensive feedback control system developed enables plants to strengthen their defenses to withstand attack by re-wiring existing gene connectionsThe system uses same approach as aircraft autopilots use to counteract turbulence.

Odors are perceived the same way by hunter-gatherers and Westerners

EurekAlert! - Dom, 06/17/2018 - 22:00
Previous research has shown the hunter-gatherer Jahai are much better at naming odors than Westerners. They even have a more elaborate lexicon for it. New research by language scientist Asifa Majid of Radboud University shows that despite these linguistic differences, the Jahai and Dutch find the same odors pleasant and unpleasant.

Using gold nanoparticles to trigger sequential unfolding of 3D structures

EurekAlert! - Dom, 06/17/2018 - 22:00
Researchers have developed a technique that takes advantage of gold nanoparticles to trigger the sequential unfolding of three-dimensional structures using different wavelengths of light.

In the gaping mouth of ancient crocodiles

EurekAlert! - Dom, 06/17/2018 - 22:00
A new study by a team of international experts, led by University of Witwatersrand Ph.D. candidate Kathleen Dollman and Professor Jonah Choiniere published today in the American Museum Novitates, endeavoured to further explore the mouth of one of the earliest occurring and least understood groups of crocodilians, the shartegosuchids.

How the brain plays a role in rheumatoid arthritis inflammation

EurekAlert! - Dom, 06/17/2018 - 22:00
A new study from researchers at Michigan Medicine explores links between chronic joint inflammation and cognitive impairment.

New material for splitting water

EurekAlert! - Dom, 06/17/2018 - 22:00
Solar energy is clean and abundant, but when the sun isn't shining, you must store the energy in batteries or through a process called photocatalysis. In photocatalytic water splitting, sunlight separates water into hydrogen and oxygen, which can then be recombined in a fuel cell to release energy. Now, a new class of materials -- halide double perovskites -- may have just the right properties to split water, according to research in Applied Physics Letters.

Nature programmes could put a spring in your step

EurekAlert! - Dom, 06/17/2018 - 22:00
A new study shows that watching films set in a natural environment boosts body image.

When consumers don't want to talk about what they bought

EurekAlert! - Dom, 06/17/2018 - 22:00
One of the joys of shopping for many people is the opportunity to brag about their purchases to friends and others. But new research found one common situation in which people would rather not discuss what they just bought: when they're feeling like money is a little tight. In a series of studies, researchers found that consumers who felt financially constrained didn't want to talk about their purchases, large or small, with friends or strangers.

Cell technology used to treat osteochondral knee defect

EurekAlert! - Dom, 06/17/2018 - 22:00
As the publication describes, autologous cells of stromal vascular fraction were transplanted to a 36-year-old man with the use of fibrin matrix. The patient, whose injury had been caused by a fall, then has been under supervision for two years.

Lots of news and lots of contacts at ZPID Twin Conference

EurekAlert! - Dom, 06/17/2018 - 22:00
The Leibniz Institute for Psychology Information (ZPID) had organized the two conferences from June 7-12 at its seat in Trier, Germany.

Study examines first birth cohort to receive HPV vaccine: The vaccine works

EurekAlert! - Dom, 06/17/2018 - 22:00
Girls in the first birth cohort to be offered and receive the HPV vaccine showed a lower degree of dysplasia which may eventually lead to cervical cancer than a birth cohort from 1983. This is the conclusion of a new study conducted by researchers at the University of Copenhagen, who have been the first to study the vaccine's effect on the general population.

Research finds new way to determine protection of Men B vaccine against different strains

EurekAlert! - Dom, 06/17/2018 - 22:00
This approach is being assessed by Public Health England for its potential to routinely test all meningococcal disease cases.

New radiological procedure for the diagnosis of liver disease

EurekAlert! - Dom, 06/17/2018 - 22:00
Researchers from Charité -- Universitätsmedizin Berlin have successfully tested a new technology for use in the assessment of overweight adolescents with liver disease. Known as 'time-harmonic elastography' (THE), the technology enables physicians to determine the disease's severity without having to resort to invasive liver biopsies. The results of this research have been published in Radiology.

'Be personal and appreciative': Research shows effective responses to online feedback

EurekAlert! - Dom, 06/17/2018 - 22:00
As more patients leave feedback on online platforms including social media, new research shows how health and social care organisations can offer value in their response. The study was led by University of Plymouth researcher Rebecca Baines and colleagues in collaboration with James Munro at online platform Care Opinion, and they will be sharing the full findings at a webinar on Thursday, June 21.

Trojan Horse: How a killer fungus unleashes meningitis and brain infection

EurekAlert! - Dom, 06/17/2018 - 22:00
In a world first, Australian researchers have revealed how a deadly fungus and primary cause of life-threatening meningitis exploits the immune system like a 'Trojan Horse' to promote infection.
