As many as one in four women attending sexual and reproductive healthcare services say they are not allowed to take control of their own reproductive lives, reveals a review of the available evidence, published today in BMJ Sexual & Reproductive Health.
As well as not being able to actively choose whether to use contraceptives, or start or continue with a pregnancy, this 'reproductive control' also takes the form of 'contraceptive sabotage', which includes covert removal of a condom during sex, so invalidating consent, the research shows.
Researchers have used artificial intelligence to support the instant diagnosis of one of the top causes of blindness, diabetes-related eye disease, in its earliest stages.
Diabetic retinopathy is the leading cause of vision loss in adults* and its impact is growing worldwide, with 191 million people set to be affected by 2030**.
There are no early-stage symptoms and the disease may already be advanced by the time people start losing their sight. Early diagnosis and treatment can make a dramatic difference to how much vision a patient retains.
A study from the University of Notre Dame has found that the properties of a material commonly used to create conductive or protective films and encapsulate drug compounds - and the conditions in which this material will disassemble to release that medication - may be different than initially thought.
Published in the Journal of the American Chemical Society, the study aimed to identify the conditions under which polyelectrolyte complexes, or PECs, would assemble and stay assembled. The researchers found new, important differences between strong and weak PECs.
BEER-SHEVA, Israel...January 4, 2019 - Ben-Gurion University researchers have developed a new satellite imaging system that could revolutionize the economics and imagery available from space-based cameras and even earth-based telescopes.
"This is an invention that completely changes the costs of space exploration, astronomy, aerial photography, and more," says Angika Bulbul, a BGU Ph.D. candidate under the supervision of Prof. Joseph Rosen in the BGU Department of Electrical and Computer Engineering.
Every time we look at a face, we take in a flood of information effortlessly: age, gender, race, expression, the direction of our subject's gaze, perhaps even their mood. Faces draw us in and help us navigate relationships and the world around us.
How the brain does this is a mystery. Understanding how facial recognition works has great value--perhaps particularly for those whose brains process information in ways that make eye contact challenging, including people with autism. Helping people tap into this flow of social cues could be transformational.
Two Veterans Affairs researchers have explored how memory is tied to the hippocampus, with findings that will expand scientists' understanding of how memory works.
As a non-noble metal, copper oxidizes more easily to positive valence (Cu+ or Cu2+) than same-family elements Au or Ag. In general, this chemical property is mainly determined by electron structure. Can we change the chemical properties of an element by regulating its electron structure? Can Cu act as a noble metal in catalytic reactions?
SEATTLE - Globally, one in four people over age 25 is at risk for stroke during their lifetime, according to a new scientific study.
Researchers found a nearly five-fold difference in lifetime stroke risk worldwide, with the highest risk in East Asia and Central and Eastern Europe, and lowest in sub-Saharan Africa. The lifetime stroke risk for 25-year-olds in 2016 ranged from 8% to 39%, depending on where they live; people in China have the highest risk.
Workplace resilience programmes, designed to bolster mental health and wellbeing, and encourage employees to seek help when issues arise, might not make any difference, suggests research published online in Occupational & Environmental Medicine.
These programmes are becoming increasingly popular in the belief that they are not only good for employee mental health, but also for employers' overheads, despite relatively little sound evaluation of their effectiveness, say the researchers.
When it comes to self-assessment, new U of T research suggests that maybe we do have a pretty good handle on our own personalities after all.
"It's widely assumed that people have rose-coloured glasses on when they consider their own personality," says Brian Connelly, an associate professor in U of T Scarborough's Department of Management.
"We found that isn't necessarily the case, that on average people don't show any trend in rating themselves more favourably than they're rated by their peers."
BOSTON - Already affecting more than five million Americans older than 65, Alzheimer's disease is on the rise and expected to impact more than 13 million people by 2050. Over the last three decades, researchers have relied on neuroimaging - brain scans such as magnetic resonance imaging (MRI) or positron emission tomography (PET) - to study Alzheimer's disease and other neurodegenerative diseases. Yet these studies have so far failed to deliver consistent findings, leaving scientists with no clear path to finding treatments or cures.
Astronomers have captured one of the most detailed views of a young star taken to date, and revealed an unexpected companion in orbit around it.
While observing the young star, astronomers led by Dr John Ilee from the University of Leeds discovered it was not in fact one star, but two.
The main object, referred to as MM 1a, is a young massive star surrounded by a rotating disc of gas and dust that was the focus of the scientists' original investigation.
What if, instead of turning up the thermostat, you could warm up with high-tech, flexible patches sewn into your clothes - while significantly reducing your electric bill and carbon footprint?
Argonne researchers have demonstrated a new technique’s viability for membranes.
Whether it's tap water or a cup of coffee, almost everything we drink passes through some kind of filter. The ability to transform liquids this way is essential to daily life, yet it often rests on relatively delicate membranes that can quickly clog or degrade.
Dec 10, 2018 - Aurora, Ore. - Hazelnuts are poised to be the "it" nut for 2019, and new research suggests that adding hazelnuts to your daily diet could bode well for long-term health.
