How old is your brain compared to your chronological age? A new measure of brain health developed by researchers at Rush University Medical Center may offer a novel approach to identifying individuals at risk of memory and thinking problems, according to research results published in Alzheimer's & Dementia: The Journal of the Alzheimer's Association on June 1.

You may think a little white lie about a bad haircut is strictly for your friend's benefit, but your brain activity says otherwise. Distinct activity patterns in the prefrontal cortex reveal when a white lie has selfish motives, according to new research published in JNeurosci.

1. Tai chi about equal to conventional exercise for reducing belly fat in middle-aged and older adults
A new study published in Proceedings of National Academics of Sciences finds that individuals who falsely believe they are able to identify false news are more likely to fall victim to it. In the article published today, Ben Lyons, assistant professor of communication at the University of Utah, and his colleagues examine the concern about the public's susceptibility to false news due to their inability to recognize their own limitations in identifying such information.
Very high atmospheric CO2 levels can explain the high temperatures on the still young Earth three to four billion years ago. At the time, our Sun shone with only 70 to 80 per cent of its present intensity. Nevertheless, the climate on the young Earth was apparently quite warm because there was hardly any glacial ice. This phenomenon is known as the 'paradox of the young weak Sun.' Without an effective greenhouse gas, the young Earth would have frozen into a lump of ice.
Art Garfunkel once described his legendary musical chemistry with Paul Simon, "We meet somewhere in the air through the vocal cords ... ." But a new study of duetting songbirds from Ecuador, the plain-tail wren (Pheugopedius euophrys), has offered another tune explaining the mysterious connection between successful performing duos.
It's a link of their minds, and it happens, in fact, as each singer mutes the brain of the other as they coordinate their duets.
Three groups (Dr. James Birchler's group from University of Missouri, Dr. Jan Barto's group from Institute of Experimental Botany of the Czech Academy of Sciences and Dr. HAN Fangpu's group from the Institute of Genetics and Developmental Biology of the Chinese Academy of Sciences) recently reported a reference sequence for the supernumerary B chromosome in maize in a study published online in PNAS (doi:10.1073/pnas.2104254118).
UCLA HEALTH RESEARCH BRIEF
FINDINGS
A new study shows that tai chi mirrors the beneficial effects of conventional exercise by reducing waist circumference in middle-aged and older adults with central obesity. The study was done by investigators at the University of Hong Kong, The Chinese University of Hong Kong; Chinese Academy of Sciences; and UCLA.
BACKGROUND
PULLMAN, Wash. - No billionaires live among the Tsimane people of Bolivia, although some are a bit better off than others. These subsistence communities on the edge of the Amazon also have fewer chronic health problems linked to the kind of dramatic economic disparity found in industrialized Western societies.
An enhanced learning environment during the first five years of life shapes the brain in ways that are apparent four decades later, say Virginia Tech and University of Pennsylvania scientists writing in the June edition of the Journal of Cognitive Neuroscience.
By including multi-ethnic participants, a largescale genetic study has identified more regions of the genome linked to type 2 diabetes-related traits than if the research had been conducted in Europeans alone.
Between 1991 and 2018, more than a third of all deaths in which heat played a role were attributable to human-induced global warming, according to a new article in Nature Climate Change.
LOS ANGELES (May 31, 2021) -- Today The Lundquist Institute announced that its investigators contributed data from several studies, including data on Hispanics, African-Americans and East Asians, to the international MAGIC collaboration, composed of more than 400 global academics, who conducted a genome-wide association meta-analysis led by the University of Exeter. Now published in Nature Genetics, their findings demonstrate that expanding research into different ancestries yields more and better results, as well as ultimately benefitting global patient care.
Gender roles absorbed at an early age seem to have shaped today's youth regarding their involvement in politics, in line with traditional stereotypes, concludes a new study, conducted amongst adolescents and young adults aged between 15 and 30 in Italy, within the Horizon 2020 project: "CATCH-EyoU. Processes in Youth's Construction of Active EU Citizenship".
