Obesity and a high-salt diet are both bad for our hearts but they are bigger, seemingly synergistic risks for females, scientists report.

Amsterdam, April 29, 2021 - The clinical presentation and underlying biology of Parkinson's disease (PD) varies significantly, but attempts to cluster cases into a limited number of subtypes have questionable applicability and relevance, reports the international Task Force for PD Subtypes in the Journal of Parkinson's Disease. Their systematic review of studies reporting a subtyping system for the first time concludes that new approaches are needed that acknowledge the individual nature of the disease and are more aligned with personalized medicine.

A third of children and adolescents develop a mental health problem after a concussion, which could persist for several years post-injury, according to a new literature review.

Osaka University and the University of Adelaide researchers have invented ultrasmall and ultrahigh-speed multiplexers that can separate and combine electromagnetic waves in the terahertz frequency bands, accelerating research and development of wireless communications towards 1 Terabit/s.

The choice between two non-invasive diagnostic tests is a common dilemma in patients who present with chest pain. Yale cardiologist Rohan Khera, MD, MS, and colleagues have developed ASSIST©, a new digital decision-aiding tool.

Melting of the Arctic ice sheets caused rapid methane release from the ocean floor during the last two deglaciations, according to a new study in Geology. A similar release is likely to happen today, and should be included in climate models, say the scientists.

Research from Lancaster University Management School and Texas Tech University shows toxic pollution hits poorer populations hardest as firms experience more pollutant releases and spend less money on waste management in areas with lower average incomes.

A research group working at Uppsala University has succeeded in studying 'translation factors' - important components of a cell's protein synthesis machinery - that are several billion years old. By studying these ancient 'resurrected' factors, the researchers were able to establish that they had much broader specificities than their present-day, more specialised counterparts.

Researchers believes that electrochemical biosensors will help defeat the coronavirus. These are high sensitivity and low cost diagnostic tools for detecting Covid-19.

A collaboration between experts and a Danish-based, global reaching patient organization has resulted in a groundbreaking medical publication, where guidelines are being presented on how to manage patients with unexplained low blood sugar.

Using ultra-high field magnetic resonance imaging (MRI) to map the brains of people with Down syndrome (DS), researchers from Case Western Reserve University, Cleveland Clinic, University Hospitals and other institutions detected subtle differences in the structure and function of the hippocampus--a region of the brain tied to memory and learning.

Older people with vision loss are significantly more likely to suffer mild cognitive impairment, which can be a precursor to dementia, according to a new study published in the journal Ageing Clinical and Experimental Research.

When heavy ions, accelerated to the speed of light, collide with each other in the depths of European or American accelerators, quark-gluon plasma is formed for fractions of a second, or even its "cocktail" seasoned with other particles. According to scientists from the IFJ PAN, experimental data show that there are underestimated actors on the scene: photons. Their collisions lead to the emission of seemingly excess particles, the presence of which could not be explained.

A new strain of the Lacticaseibacillus rhamnosus GG probiotic is able to utilise both lactose and casein as well as reproduce in dairy products. The discovery can make it unnecessary to separately add the probiotic to dairy products, in addition to which it could fare better in the intestine, boosting gut health.

A detailed analysis combining seafloor mapping and earthquake and gravity data shows that the oceanic crust under the Red Sea is older than previously thought.

An international research team including scientists from ETH Zurich has shownthat almost all the world's glaciers are becoming thinner and losing mass - andthat these changes are picking up pace. The team's analysis is the most comprehensive and accurate of its kind to date.

Researchers at Aalto University have now discovered that electrodes in lithium batteries containing cobalt can be reused as is after being newly saturated with lithium. In comparison to traditional recycling, which typically extracts metals from crushed batteries by melting or dissolving them, the new process saves valuable raw materials, and likely also energy.

A top-level international research team including researchers from the University of Eastern Finland has developed a new algorithm for the diagnostics of dementia. The algorithm is based on blood and cerebrospinal fluid biomarker measurements. These biomarkers can be used to aid setting of an exact diagnosis already in the early phases of dementia.
