Inflate cells to observe their inner life

Researchers at the University of Geneva have developed a new technique called Ultrastructure Expansion Microscopy (U-ExM), which allows for the visualization of cellular structures and protein complexes at a nanoscale. This method enables the detection of biochemical modifications and mapping of large intracellular molecular complexes.

Economic climate feedbacks

Researchers found that climate-driven economic losses can offset natural warming feedbacks, but this comes with increased inequality and reduced resources for mitigating climate change. The study suggests that climate-related economic activity slowdowns can temporarily reduce atmospheric CO2 levels.

URI researcher: Oyster aquaculture limits disease in wild oyster populations

A URI researcher found that oyster aquaculture can limit the spread of disease among wild oysters. Aquaculture operations can reduce disease by filtering parasites from the water and holding oysters long enough to prevent their development. Intensive oyster aquaculture, when done correctly, can be beneficial for wild populations.

One-third of Americans consider living abroad

A new study reveals that approximately one-third of all US-born US citizens living in the US are considering leaving to live abroad. The main motivations cited are exploration, retirement, and dissatisfaction with their current situation. National identity and networks played a significant role in shaping these aspirations.

Patients with heart failure have lower risk of death, hospital admission if seen by physician in first 7 days after emergency department discharge

Patients with heart failure who receive early follow-up by a physician within 7 days of emergency department discharge have lower risk of death and hospital admissions. The study found that 47% of patients were seen by a physician within a week, with the lowest death rate in those who received care within 7 days.

A fire-breathing dragon helps fight ember attacks on thatched-roof buildings

Researchers used the NIST Dragon to simulate ember attacks on thatched-roof buildings, revealing ignition occurred within 90 seconds and flames penetrated completely through the roofing assembly. The study's findings will help Japanese fire services develop effective counter measures and mitigate damage from large outdoor fires.

Medical emergency department visits can indicate increased suicide risk among teens and young adults

A new study identifies medical conditions that increase the risk of self-directed violence among teens and young adults visiting emergency departments. These conditions include epilepsy, seizures, multiple pain visits, syncope, vomiting, and dental complaints, highlighting the importance of EDs in suicide prevention.

Folate deficiency creates hitherto unknown problems in connection with cell division

Researchers from the University of Copenhagen found that folate deficiency creates far more damaging chromosomal abnormalities than previously known. This can lead to problems with cell division and DNA replication, increasing the risk of diseases like infertility, mental health disorders and cancer.
