Flexibility in the workplace is the key to helping women maintain their career trajectory after childbirth, new research by the University of Kent has shown.

New study rebuts the claim that antidepressants do not work

EurekAlert! - Jue, 08/17/2017 - 22:00
A theory that has gained considerable attention in international media, including Newsweek and the CBS broadcast 60 minutes, suggest that antidepressant drugs, such as the SSRIs, do not exert any actual antidepressant effect. A research group at the Sahlgrenska Academy has now analyzed data from clinical trials and can rebut this theory.

The power of perovskite

EurekAlert! - Jue, 08/17/2017 - 22:00
OIST researchers improve perovskite-based technology in the entire energy cycle, from solar cells harnessing power to LED diodes to light the screens of future electronic devices and other lighting applications.

How whip-like cell appendages promote bodily fluid flow

EurekAlert! - Jue, 08/17/2017 - 22:00
Researchers at Nagoya University revealed that a molecule called Daple is essential for the correct orientation and coordinated beating of cilia on the surface of cells lining ventricles in the brain. Without Daple, the cilia develop a random arrangement and cannot produce a uniform flow of CSF. This in turn leads to a build-up of fluid, which is associated with swelling of the head, known as hydrocephalus.

Drug resistance in an intestinal parasite of piglets confirmed for the first time

EurekAlert! - Jue, 08/17/2017 - 22:00
Cystoisospora suis causes diarrhea especially in newborn piglets and spreads quickly across farms. European farmers preventively use toltrazuril to control parasite development. In contrast to congeneric chicken parasites, no resistance to toltrazuril was described in pig parasites until recently. Researchers of Vetmeduni Vienna now confirmed ineffectivness of toltrazuril against a Dutch isolate. Although the resistance develops slowly, monitoring should be intensified due to the lack of alternative treatment options and hygiene measures should be increased.

Initial preliminary assessment of the health risks posed by longer-term consumption of foods contaminated with fipronil

EurekAlert! - Jue, 08/17/2017 - 22:00
Based on currently available knowledge, the German Federal Institute for Risk Assessment (BfR) assumes that illegal applications of products containing fipronil have apparently been carried out over an extended period of time. For this reason, the longer term consumption of foods contaminated with fipronil has to be given due consideration when assessing the risks.

Lasers used to detect risk of heart attack and stroke

EurekAlert! - Jue, 08/17/2017 - 22:00
Patients at risk of heart attacks and strokes may be spotted earlier thanks to a diagnosis tool that uses near-infrared light to identify high-risk arterial plaques, according to research carried out at WMG, University of Warwick, the Baker Institute and Monash University.

Hypertension during pregnancy may affect women's long-term cardiovascular health

EurekAlert! - Jue, 08/17/2017 - 22:00
Women who experience hypertension during pregnancy face an increased risk of heart disease and hypertension later in life, according to a new study.

A heart made of spider silk

EurekAlert! - Jue, 08/17/2017 - 22:00
Ever more people are suffering from cardiac insufficiency. The main cause of reduced cardiac functionality lies in the irreversible loss of cardiac muscle cells due to disease, especially ischemic diseases such as cardiac infarction. There is still no treatment to reverse damage of this nature. Research is ongoing to develop methods of repairing such damage to normalize cardiac function. A promising approach: cardiac muscle tissue made of spider silk.

Fipronil in foods containing eggs: Estimations of maximum tolerable daily consumption

EurekAlert! - Jue, 08/17/2017 - 22:00
The German Federal Institute for Risk Assessment has prepared a health risk assessment based on limited available data on fipronil levels in foods (containing eggs) in Germany.

Identifying individual atmospheric equatorial waves from a total flow field

EurekAlert! - Jue, 08/17/2017 - 22:00
A new study presents a method for identifying individual equatorial waves in wind and geopotential height fields using horizontal wave structures derived from classical equatorial wave theory.

Allergies: Cross-reactivity between cypress pollen and peaches/citrus fruits explained

EurekAlert! - Jue, 08/17/2017 - 22:00
In collaboration with teams from the Czech Republic and Japan, researchers from the Institut Pasteur, (AP-HP), and (AP-HM) have identified the likely origin of the cross-reactivity between cypress pollen, peaches and citrus fruits. Their work has shown that these sources contain allergens belonging to a new family of proteins involved in pollen food associated syndrome. This discovery, published in JACI on Aug. 3, paves the way for the development of novel allergy diagnostic tests.

Right kind of collaboration is key to solving environmental problems

EurekAlert! - Jue, 08/17/2017 - 22:00
Society's ability to solve environmental problems is tied to how different actors collaborate and the shape and form of the networks they create, says a new study from researchers at Stockholm Resilience Centre which is published in the journal Science.

CAS scientists make autism advance using monkey model

EurekAlert! - Jue, 08/17/2017 - 22:00
Recently, researchers from Dr. Zhang Yongqing's group at the Institute of Genetics and Developmental Biology of the Chinese Academy of Sciences (CAS) found neurodevelopmental abnormality in a SHANK3-deficient non-human primate for the first time.

Gene variant activity is surprisingly variable between tissues

EurekAlert! - Jue, 08/17/2017 - 22:00
Every tissue has its own pattern of active alleles, a large-scale study led by an international team of scientists at the CeMM Research Center for Molecular Medicine of the Austrian Academy of Sciences has found. Researchers of the former group of Denise Barlow were able to show that the differential allele activity is regulated by tissue-specific, regulatory DNA elements known as enhancers - a process that could also be involved in many diseases.

Histone 1, the guardian of genome stability

EurekAlert! - Jue, 08/17/2017 - 22:00
Genomic instability is the main risk factor for tumor development in humans. Therefore understanding its origin and and exploring therapeutic targets is paramount.Histone 1 silences a region of the genome that causes irreparable DNA damage when translated and is lethal for the organism.

The Western Ghats of India revealed two new primitive species of earthworm

EurekAlert! - Jue, 08/17/2017 - 22:00
Having conducted a survey of the earthworms in the Western Ghats mountains, India, a team of four scientists discovered two species new to science. Both belong to a primitive family. They are described in the open access journal ZooKeys.

Citrus: From luxury item to cash crop

EurekAlert! - Jue, 08/17/2017 - 22:00
New research from Tel Aviv University reveals that citrons and lemons were status symbols for the ancient Roman ruling elite. It also plots the route and evolution of the citrus trade in the ancient Mediterranean.

Doctors exploring how to prescribe income security

EurekAlert! - Jue, 08/17/2017 - 22:00
Physicians at St. Michael's Hospital are studying how full-time income support workers hired by health-care clinics can help vulnerable patients or those living in poverty improve their finances and their health.

Climate change and habitat conversion combine to homogenize nature

EurekAlert! - Jue, 08/17/2017 - 22:00
Climate change and habitat conversion to agriculture are working together to homogenize nature, indicates a study in the journal Global Change Biology led by the University of California, Davis. In other words, the more things change, the more they are the same.
