Epithelial GPS: Position of RNAi machinery is associated with epithelial identity

Researchers found that RNAi machinery primarily localizes at apical adherens junctions in healthy colon cells but becomes mis-localized in colon cancer. This localization plays a crucial role in maintaining epithelial homeostasis, with restoration of the RNAi machinery potentially serving as a brake on tumor progression.

How does the brain link events to form a memory? Study reveals unexpected mental processes

Scientists at Columbia's Zuckerman Institute mapped the brain's complex calculations to link distinct events separated in time, shedding light on anxiety and trauma-related disorders. The hippocampus uses bursts of activity to form associations, saving energy by encoding information in synapses rather than constant electrical activity.

Computer vision helps SLAC scientists study lithium ion batteries

Researchers at SLAC National Accelerator Laboratory used computer vision and X-ray tomography data to understand how nickel-manganese-cobalt cathodes degrade over time. They found that particles detaching from the carbon matrix contribute significantly to battery decline, contradicting previous assumptions about making smaller particle...

To err is human, to learn, divine

The human brain balances complexity and accuracy when processing patterns, with errors playing a crucial role in learning and cognition. The new model suggests that the brain constantly strives to represent things in simple terms, with participants showing quicker responses to sequences generated by modular networks.

Perspiration problems? No sweat!

Osaka University researchers have generated immortalized human eccrine sweat gland myoepithelial cells (iEM cells), which can be cultured for over ten generations. This achievement has the potential to develop next-generation antiperspirants and promote research on sweat dysfunction and regeneration.

Forecasting urbanization

Researchers used data science and machine learning to forecast urbanization patterns, predicting a 1.8-5.9-fold increase in urban areas by 2100. Global simulations show countries transitioning from rapidly to steadily to urbanized over time, with varying impacts on environment and society.

Burning out in silence

A study by North Dakota State University and HSE University found a positive correlation between Russian's latent dissent at work and emotional burnout. Employees often express dissent through venting to co-workers or friends rather than management, leading to burnout and work-life imbalance.

Editorial: US healthcare must take a more proactive approach to prepare for future disasters

The COVID-19 pandemic exposed major deficiencies in the US healthcare system, highlighting the need for improved health maintenance and emergency preparedness. The article argues that public health systems are underfunded and understaffed, leading to inadequate responses to slow-moving mass casualty incidents like COVID-19.

Twitter -- not just pointless babble

The new book Twitter - A Biography explores the journey of Twitter from its inception to its current status as a global platform for news, political messages, and crisis communication. Professors Jean Burgess and Nancy Baym argue that Twitter's original social value has been lost amidst noise of antagonistic debate and self-promotion.

Quantum jump tipping the balance

Researchers at the Max Planck Institute for Nuclear Physics have successfully measured infinitesimal changes in mass of individual atoms for the first time, opening a new world for precision physics. The team discovered a previously unobserved quantum state in rhenium, which could be interesting for future atomic clocks.

The Lancet Rheumatology: Small observational study of patients with severe COVID-19 treated with the arthritis drug anakinra finds clinical improvements

A small observational study of 29 Italian patients with severe COVID-19 and hyperinflammation found that high-dose intravenous anakinra was associated with respiratory improvements and reduced signs of cytokine storm in 72% of patients. The treatment was generally safe, but more research is needed to fully understand its effectiveness.

New review of studies shows no link between prenatal antidepressant exposure and autism

A new meta-analysis by Jeffrey Newport found no association between prenatal antidepressant use and autism in children, despite previous studies suggesting a potential link. Limited access to healthcare among ethnic minority and immigrant mothers was identified as the root cause of bias, leading to inaccurate study results.

Stem cells shown to delay their own death to aid healing

Researchers have found that stem cells in planarians can postpone their own death to respond to an injury, allowing them to gather around the site of the wound and mount a response. This unique ability has implications for cancer research and therapies, particularly when examining chemotherapy and surgery options.

Vitamin D linked to low virus death rate -- Study

A new study has found an association between low average levels of vitamin D and high numbers of COVID-19 cases and mortality rates across 20 European countries. Vitamin D modulates the response of white blood cells, preventing excessive inflammatory cytokine release, which is a key factor in COVID-19 severity.
