Exercise slows down cognitive decline in older adults

Exercise in older people is associated with a slower rate of decline in thinking skills that occurs with aging. People who reported light to no exercise experienced a decline equal to 10 more years of aging as compared to people who reported moderate to intense exercise, according to a population-based observational study published in the March 23, 2016, online issue of Neurology, the medical journal of the American Academy of Neurology.

Diet and lifestyle may play greater role than genetics in cataract development, severity

A diet rich in vitamin C could cut risk of cataract progression by a third, suggests a study being published online today in Ophthalmology, the journal of the American Academy of Ophthalmology. The research is also the first to show that diet and lifestyle may play a greater role than genetics in cataract development and severity.

Fatty acid supplement can help reduce early preterm births

Cupid was obviously a full-term baby. It's fitting then that a researcher named Valentine and her colleagues will oversee a new multicenter National Institutes of Health study to determine whether an over the counter fatty acid supplement, called DHA (Docosahexaenoic acid, an omega-3 fatty acid), can assist with reducing early preterm births.

Novel mechanism can suppress blood vessel leakage, reduce tumour spread in mice

Cancer therapy is often hampered by the accumulation of fluids in and around the tumour, which is caused by leakage from the blood vessels in the tumour. Researchers at Uppsala University now show how leakage from blood vessels is regulated.

German scientists analyse LOV proteins using neutron scattering

The internal movements of proteins can be important for their functionality; researchers are discovering more and more examples of this. Now, with the aid of neutron spectroscopy, dynamic processes have also been detected in so-called "LOV photoreceptors" by scientists from Jülich, Aachen, Dusseldorf and Garching near Munich.

Research shows tumor suppressor protein regulates polarity genes

What does Brad Pitt have in common with a fruit fly? His Hollywood hairstyles cover a prominent cowlick - the swirl of hair that that is caused by a patterning mechanism also active in our two-winged friends -- that similarly feature "polarized" hair patterns.

Research: X and Y DNA swapping may occur more often than previously thought

It turns out that the rigid "line in the sand" over which the human sex chromosomes---the Y and X--- go to avoid crossing over is a bit blurrier than previously thought. Contrary to the current scientific consensus, Arizona State University assistant professor Melissa Wilson Sayres has led a research team that has shown that X and Y DNA swapping may occur much more often.

Transcranial magnetic stimulation of STS can change behaviour of gaze

A study financed by the Assistance Publique-Hôpitaux de Paris has been conducted under the direction of Monica Zilbovicius in the Inserm Unit 1000 on a particular region of the brain, the superior temporal sulcus (STS), influencing perception and behaviour of the gaze.

Austrian scientists detect new membrane-bound arsenic substances in herring caviar

Seafish are known for their capability to accumulate toxic trace elements like mercury or arsenic. These elements are metabolized and end up chemically bound to organic compounds found in cell constituents like the membranes.

New worldwide collaboration aims to speed up effective diagnosis of TB

As World TB day (24 March) marks global efforts to eliminate tuberculosis as a public health problem by 2035, Oxford University researchers, in partnership with Public Health England (PHE), will lead a new worldwide collaboration called CRyPTIC to speed up diagnosis of the disease.

Penn neurologists uncover new genetic cause of Charcot-Marie-Tooth Disease

Charcot-Marie-Tooth Disease (CMT) is a family of inherited disorders of the peripheral nervous system, affecting approximately one in 2,500 Americans. Its most common iteration, CMT1, comes in many forms, most of which have to date been linked to a small set of causative genes.

Guardian system can predict risk of dangerous diseases

If an infectious disease outbreak or an attack using an agent such as anthrax were to occur in Chicago, it most likely first will be noticed in emergency rooms throughout the city. Swift identification of the cause of an incoming patients' illness could be crucial to public health and safety personnel being able to intervene in time to save lives.
