Boxers and mixed martial arts (MMA) fighters may see some recovery in their thinking and memory skills as well as brain structure after they stop fighting, according to a new study.

A combination of seven healthy lifestyle habits including sleeping seven to nine hours daily, exercising regularly and having frequent social contact was associated with a lower risk of dementia in people with type 2 diabetes, according to a study published in the September 14, 2022, online issue of Neurology®, the medical journal of the American Academy of Neurology.

Chemists have discovered a new oxidation state of rhodium. This chemical element is one of the most catalytically important platinum-group metals and is used, for example, in catalytic converters for automobiles. Rhodium is actually already well studied.

Nearly nine in ten cases of sudden cardiac death (SCD) due to hypertrophic cardiomyopathy (HCM) in young people are preceded by symptoms, ECG abnormalities or a positive family history, according to a new study. Those findings suggest that expanding cardiac screening beyond competitive athletes could aid in the prevention of SCD in the young population with HCM.

Tiny crystals in ancient animal dung serve as key evidence in a new analysis suggesting the possibility that hunter-gatherers at Abu Hureyra, Syria, may have tended small numbers of animals just outside their dwellings between 12,800 and 12,300 years ago.

Researchers demonstrate a clear connection between personality in wandering albatross (Diomedea exulans) and the likelihood of divorce. Though the link between personality and relationship outcomes in humans is well-established, this is the first study to do so with animals.

In a new study, researchers across North America have modeled how antimicrobial use impacts the emergence of antimicrobial resistance in Escherichia coli isolated from Canadian turkey flocks.

A three-year study in northeastern Illinois and northwestern Indiana found that -- even at small scales -- emergent wetlands or ponds support many wetland bird species. The study also found that, at least in the years surveyed, the level of urbanization had little effect on most of the studied species' use of such sites, provided the right kinds of habitat were available.

Most viral infections negatively affect an organism's health, but one plant virus in particular -- soybean vein necrosis orthotospovirus, often referred to as SVNV -- may actually benefit a type of insect that commonly feeds on soybean plants and can transmit the virus to the plant, causing disease, according to new research.

Researchers have developed low-cost, painless, and bloodless tattoos that can be self-administered and have many applications, from medical alerts to tracking neutered animals to cosmetics.

A new study describes the rules by which physical force on cells affects squishy biocomputers inside, and the action of a related kinase known to be overactive as tau tangles form in the brain cells of Alzheimer's patients.

Contrast-enhanced in-phase Dixon sequence could reduce the need for correlation among other imaging modalities to better identify areas of prior biopsy during breast MRI interpretation, according to a new study.

Scientists have harnessed the potential of bacteria to help build advanced synthetic cells which mimic real life functionality.

Astronomers have developed a new technique to identify small planets hidden in protoplanetary disks.

Researchers have discovered a specific network of proteins that is necessary to restore hearing in zebrafish through cell regeneration. The study may inform the development of treatments for hearing loss in humans.

Researchers present the most precise test yet of the weak equivalence principle, a key component of the theory of general relativity. The report describes the final results from the MICROSCOPE mission, which tested the principle by measuring accelerations of free-falling objects in a satellite orbiting Earth.

Crops bred to thrive in single-crop settings begin adapting to growing in multispecies environments over just two generations, shows a new study.

A team has developed a novel approach for comparing neural networks that looks within the 'black box' of artificial intelligence to help researchers understand neural network behavior. Neural networks recognize patterns in datasets; they are used everywhere in society, in applications such as virtual assistants, facial recognition systems and self-driving cars.

Just as optical illusions can fool the eye to present a distorted image of reality, moral illusions can fool our decision-making ability, making us more selfish. But the results also show that we are more likely to vote for the good of all when taking part in democratic decisions.

A two-pronged approach to imaging breast density in mice resulted in better detection of changes in breast tissue, including spotting early signs of cancer. The researchers hope that this approach will be translated from mice and improve breast imaging for people; it may also help with prognosis of disease as density can be linked to specific patterns of mammary gland growth, including signs of...

Cercarial dermatitis is caused by the larvae of blood flukes that are parasites of birds or mammals. A new study suggests that a cercarial dermatitis outbreak in South Thailand was caused by the blood fluke Schistosoma indicum. The study offers important insights on these parasites, which, apart from being a public health issue, can also infect livestock animals, threatening the sustenance of...

Researchers around the world are working to develop efficient materials to convert CO2 into usable chemical substances -- work that is particularly pressing in view of global warming. A team has discovered a new and promising approach: catalytically active molecules are nanoconfined -- meaning they are put into an environment that leaves very little space for the single molecules -- on a surface...

A team develops a nanoreactor combining magnetic material and plasmonic catalysts. Remote control of step-by-step catalytic reactions of precursor led to cinnamaldehyde product with 95% yield.

Various approaches for treating lymph node metastasis exist. But now, a research team has combined two forms of therapy to create a superior treatment method than conventional chemotherapy.
