Study reveals long-debated makeup of the molecules that help organize your cells

A new study from the University of Chicago has laid out the internal structure of polyelectrolyte complexes, a special kind of molecular assembly that helps cells keep themselves organized. The researchers used a combination of simulations and neutron scattering to determine the precise structure of these molecules, which could lead to...

Multi-level international study explores anxiety, concerns of families with a child with a neurodevelopmental condition during the COVID-19 pandemic

A global study analyzed data from over 6,600 families with a child with a neurodevelopmental condition to understand how the COVID-19 pandemic impacted their anxiety levels. The results show that anxiety increased for parents and children at the beginning of the pandemic, but decreased for children as they returned to pre-pandemic levels.

Way cool: UVA professor developing ‘freeze ray’ technology for the Air Force

UVA professor Patrick Hopkins is developing a 'freeze ray' technology to cool electronics in spacecraft and high-altitude jets, which can't be cooled by nature due to the vacuum of space. The technology uses heat-generating plasma to create localized cooling, and has been granted $750,000 by the Air Force.

When electrons slowly vanish during cooling

In certain metals, phase transitions occur gradually due to exotic laws of quantum mechanics, allowing new insights into the quantum world. Researchers at the University of Bonn and ETH Zurich have directly observed this effect, enabling a better understanding of critical slowing down in fermions.

ACP issues updated guidance for colorectal cancer screening of asymptomatic adults

The American College of Physicians recommends starting colorectal cancer screening at age 50 for asymptomatic adults with average risk. The guideline aims to balance benefits and harms of screening in this population. Screening in younger adults may not offer significant net benefit due to lower incidence rates.

BU commentary: Including sexual and gender minority populations in medical research guarantees the health and well-being of all

A recent commentary emphasizes the importance of including sexual and gender minority (SGM) populations in medical research to ensure their health and well-being. Researchers have found that SGM adults experience higher prevalence of anxiety, depression, and HIV diagnosis compared to non-SGM adults.

Human senescent fibroblasts cause lung fibrosis in mice

Researchers found that human senescent fibroblasts trigger progressive lung fibrosis in immunodeficient mice by inducing paracrine senescence and pro-fibrotic activities. The study also suggests that senolytic compounds like navitoclax can ameliorate lung fibrosis induced by senescent human fibroblasts.

Half the population to have a mental health disorder by 75

A global study led by researchers from the University of Queensland and Harvard Medical School found that one in two people will develop a mental health disorder in their lifetime. The study analyzed data from over 150,000 adults across 29 countries and found that 50% of the population develops at least one disorder by age 75.

Cell biology: How cellular powerhouses call for help when under stress

A team of researchers from Goethe University Frankfurt has discovered a central switch point in the mitochondrial signaling chain under misfolding stress. The mitochondria send two chemical signals to the cell when protein misfolding stress occurs, triggering a protective response that reduces misfolded proteins and stabilizes membranes.
