Alzheimer’s disease (AD), which affects an estimated 6.5 million adults in the United States, hits some groups harder than others. Compared to non-Hispanic whites, Hispanic Americans are 1.5 times as likely to develop AD, and African Americans are twice as likely. But scientists know little about the reasons behind these disparities, because the vast majority of AD research has been done with non-Hispanic white people. A new study that reviewed 11,871 research articles on AD brain imaging, led by researchers at the Keck School of Medicine of USC, has now revealed the extent of ...

Cancer patients saw a significant fall in Covid-related hospitalisations and mortality following the rollout of vaccines in the first panoramic study of its kind.   The research published in Scientific Reports today (Tuesday 25 July) looked at the impact of the global pandemic on case-outcome rates for cancer patients across a 21-month period from November 2020 to August 2022. The team of researchers led by the University of Birmingham found that hospitalisations in the period fell from nearly one in three patients (30.58%) to one in 13 patients (7.45%); and, case-mortality rates fell from more than one in five patients (20.53%) to less than one in 30 patients (3.25%).   Among ...

A new paper in Biology Methods & Protocols, published by Oxford University Press, shows it may be possible to design vaccines that will induce a stronger immune response to infecting pathogens, such as the virus causing COVID-19. In this study, the authors proposed and tested a new bioinformatic approach and tool that allows researchers to select parts of proteins that will elicit a strong immune response. Vaccines developed based on this approach would provide better protection from diseases. The immune system of humans (and other vertebrates) discriminates between self and non-self structures to attack and destroy the latter. T cells are the part of the immune system ...

Adding a flux during the synthesis of oxyhydrides is a promising strategy to obtain a pure, homogenous product, reveal scientists from Tokyo Tech. An SrCl2 flux promoted the melting of a part of reactants and facilitated their diffusion of reactants, which proved to be the key to producing highly pure SrVO2.4H0.6 or Sr3V2O6.2H0.8 perovskite oxyhydrides in high-pressure and high-temperature reactions. These compounds have potential as catalysts and as electrode materials for lithium-ion batteries.      Perovskite oxyhydrides ...

A mouse injured on one leg experiences an “awakening” of stem cells in the other leg as if the cells are preparing to heal an injury. Something similar happens in axolotls, which are masters at limb regeneration. Heart injuries in zebrafish can trigger certain changes in far-away organs like the kidney and brain. “In many different organisms, you can see the whole body respond to an injury. But whether or not those responses actually have any function has been unclear,” says Bo Wang, assistant professor of bioengineering at Stanford, “So that’s what we’re focusing on.” In ...

Jakarta … San Francisco … Shanghai … Phoenix … Houston. These major cities and others around the globe have many similarities, but they share one particular commonality that is concerning for residents. They are among the global cities most affected by climate change. While each of these cities has proven resilient for centuries, urban planners, community leaders and civil engineers continue to address their many environmental challenges. In preparing for these cities’ future, however, it might be more ...

Most of the earthquakes rumbling under the West’s Great Basin come in surges, clustered together in time and place. Scientists call these seismic groups “swarms,” which are a distinct category from the numerous aftershocks following a big shake, such as the 5.7 magnitude Magna quake of 2020 on the Wasatch Fault. Rather than getting spread out evenly over time, many of these small, often imperceptible quakes strike a region in a short period of time, say a few days or weeks. Central Utah has been the stage for dozens of earthquake swarms that have been recorded over the past 40 years by an ever-expanding network of seismic arrays managed by the University ...

Encouraging Latinx adolescents of Mexican origin to embrace their ethnic pride, cultural values, and connections to their cultural community contributes to positive development and better adjustment during adolescence, a new University of California, Davis, psychology study suggests. Moreover, researchers said, cultural preservation can help Latinx youth cope with adverse life experiences and social threats such as racism and discrimination. The study results were published this month in ...

A Chapman University scientist and his colleagues have determined how the Earth responds as it heats up due to climate change. The scientists say a warming world calls for a new approach in detecting how much carbon dioxide comes out of ecosystems when the temperature changes  — which tells us how well plants and soil can alleviate damage by removing carbon pollution from the atmosphere. The study is the first to find the temperature-carbon dioxide release relationship at the landscape level.  Their ...

An international team of scientists from the University of Miami Rosenstiel School of Marine, Atmospheric, and Earth Science and the Water Research Group from the Unit for Environmental Sciences and Management at the North-West University in South Africa have discovered a new species of marine cryptofauna in the Florida Keys.
