USC Roski Eye Institute researchers publish largest eye study among Latinos

LOS ANGELES - The University of Southern California (USC) Roski Eye Institute researchers and clinicians published results of the largest population-based study of adult Latinos and age-related macular degeneration (AMD) in the National Eye Institute-funded "Los Angeles Latino Eye Study (LALES)." The study, published in JAMA Ophthalmology, is the first to analyze the risk and prevalence of early and late stage AMD and its impact on quality of life for older Latinos.

An experiment seeks to make quantum physics visible to the naked eye

An experiment seeks to make quantum physics visible to the naked eye

Predictions from quantum physics have been confirmed by countless experiments, but no one has yet detected the quantum physical effect of entanglement directly with the naked eye. This should now be possible thanks to an experiment proposed by a team around a theoretical physicist at the University of Basel. The experiment might pave the way for new applications in quantum physics.

Group activities reduced depressive symptoms among older people with dementia

Group activities reduced depressive symptoms among older people with dementia

Both a high-intensity functional exercise programme and a non-exercise group activity, conducted among older care facility residents with dementia, reduced high levels of depressive symptoms. However, exercise had no superior effect on depression, according to a dissertation from Umeå University.

Mimicking the ingenuity of nature

Mimicking the ingenuity of nature

Nature shows how to do it: Photosynthesis is a process used by plants to create energy-rich organic compounds, usually in the form of carbohydrates, and oxygen (O2) from carbon dioxide (CO2) and water (H2O) driven by light. If we succeeded in mimicking this process on a large scale, numerous problems of humanity would probably be solved. Artificial photosynthesis could supply the Earth with fuels of high energy density such as hydrogen, methane or methanol while reducing the amount of carbon dioxide in our atmosphere and slowing down climate change.

Motorcycle right behind the racing cyclist can improve time in Giro prologue

Motorcycle right behind the racing cyclist can improve time in  Giro prologue

Research at TU Eindhoven, KU Leuven and the University of Liege has shown how a motorcyclist riding right behind a racing cyclist can reduce the air resistance for the cyclist by almost nine percent. In a time trial, such as this Friday's forthcoming prologue in the Giro (Tour of Italy) in Apeldoorn, this could mean a decisive advantage. The researchers advise the UCI (International Cycling Union) to extend the minimum distance between motorcycle and cyclist, also from a safety perspective, to 20 or 30 meters.

Kids' eating habits highlight need for healthier lunchboxes

New research from the University of Adelaide in Australia shows children aged 9-10 years old are receiving almost half of their daily energy requirements from "discretionary" or junk foods.

Scientists double number of known genetic risk factors for endometrial cancer

An international collaboration of researchers has identified five new gene regions that increase a woman's risk of developing endometrial cancer, one of the most common cancers to affect women, taking the number of known gene regions associated with the disease to nine.

Endometrial cancer affects the lining of the uterus. It is the fourth most commonly diagnosed cancer in UK women, with around 9,000 new cases being diagnosed each year.

Yoga and aquatic exercise can help combat MS symptoms

Exercise can have a positive influence on certain symptoms of multiple sclerosis: Patients who do yoga and aquatic exercise suffer less from fatigue, depression and paresthesia, as reported by researchers from the University of Basel and the Psychiatric University Clinics Basel in a joint study with colleagues in Iran.

Placebo effects in women are boosted by vasopressin

Philadelphia, PA, May 3, 2016 - A new study in the current issue of Biological Psychiatry suggests that women are particularly susceptible to the pain-relieving placebo effect of vasopressin.

Placebos are used to help accurately measure clinical responses/outcomes when studying the effects of medications, therapies, and other treatments. The well-known "placebo effect" is a phenomenon whereby a patient's condition improves or a patient experiences side effects despite having received a "fake" treatment.

Biophysics: Closing the ring

How bacterial cells divide in two is not fully understood. Physicists of Ludwig-Maximilians-Universitaet (LMU) in Munich now show that, at high concentrations, a crucial protein can assemble into ring-shaped filaments that constrict the cell, giving rise to two daughter cells.
