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.

Science Snapshots From Berkeley Lab - Water purification, infant-warming device, cuff-based heart disease monitor, ancient magnetic fields

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.

First study to analyse the long-term effects of persistent organic pollutants on cardiometabolic risk in adolescents

People with diabetes are at increased risk of developing a severe course of COVID-19 compared to people without diabetes. The question to be answered is whether all people with diabetes have an increased risk of severe COVID-19, or whether specific risk factors can also be identified within this group. A new study by DZD researchers has now focused precisely on this question and gained relevant insights.

Human decision-making depends on the flexible processing of complex information, but how the brain may adapt processing to momentary task demands has remained unclear. In a new article published in the journal Nature Communications, researchers from the Max Planck Institute for Human Development have now outlined several crucial neural processes revealing that our brain networks may rapidly and flexibly shift from a rhythmic to a "noisy" state when the need to process information increases.

The researchers identified troubling disparities along race, income and education lines.

Women and men are often jealous for completely different reasons. This gender difference occurs so early that it surprised the researchers.

Mantis shrimp pack one of the most powerful punches on the planet, splitting water with their explosive blows, but when do their larvae begin letting fly with their ballistic appendages and how fast? The 4.2mm long larvae begin flicking their limbs as early as 9 days after hatching, around when they begin feeding, letting lose accelerations of 22 million deg/s2 and moving at ~0.385m/s, 5-10 times faster than the larval snacks they dine on.

An analysis of Twitter activity between March 1 and Aug. 1, 2020, found strong support by U.S. users for wearing face coverings and that a media focus on anti-mask opinions fueled the rhetoric of those opposed, report University of Oregon researchers.

Researchers at The University of Texas Health Science Center at San Antonio studied 43 brain disorders and strongly affirmed a theory called the "network degeneration hypothesis." This theory holds that disease-related structural damage invades functional networks used in human behavior and often repeats in "co-alteration networks."

With the advent of next-generation sequencing technology, biologists are closer than ever to achieving the goal of constructing the phylogenetic tree of life. Large genetic studies with hundreds to thousands of specimens, however, are still bottlenecked at the specimen transcription stage, in which information from museum specimens is transcribed and copied into spreadsheets. Here, researchers present an automated collection process that utilizes a combination of unique object identifiers and QR codes.

Largest study of its kind reveals the way relative brain size of mammals changed over the last 150 million years

Scientists have recreated the reaction by which carbon isotopes made their way into different organic compounds, challenging the notion that organic compounds, such as amino acids, were formed by isotopically enriched substrates. Their discovery suggests that the building blocks of life in meteorites were derived from widely available substrates in the early solar system.

A research team from Lawson Health Research Institute has found that a simple device can reduce swelling after kidney transplantation.
