Life is tough but so are worms -- thanks to mom

A Duke University study found that worm offspring of mothers who experienced nutrient stress during pregnancy were better equipped to handle starvation later on. This is due to changes in insulin signaling transmitted via eggs, which helped the larvae develop normally and avoid reproductive abnormalities.

High rates of opioid prescriptions for osteoarthritis

Researchers found that every fourth osteoarthritis patient was prescribed opioids, with codeine and tramadol being the most commonly used. Despite not being recommended as a first-line treatment, opioids were still given to nearly a quarter of patients, highlighting a significant challenge in addressing osteoarthritis pain management.

Arctic lead pollution and economic history

A study on Arctic lead pollution reveals a significant increase in emissions from European industries during the Middle Ages, coinciding with technological advancements and economic growth. The pollution level declined substantially after pollution abatement policies were enacted, but still remains much higher than historical levels.

Moffitt researchers identify effective drug combination against uveal melanoma

Researchers at Moffitt Cancer Center have identified a new drug combination that is effective against metastatic uveal melanoma cells. The combination of an MEK inhibitor and a histone deacetylase (HDAC) inhibitor, such as panobinostat, has been shown to prevent resistance to the MEK inhibitor and enhance its anti-tumor properties.

CNIC scientists identify an essential protein for correct heart contraction and survival

A team of CNIC scientists identified SRSF3 as crucial for proper heart function and found that its loss leads to reduced expression of genes involved in contraction. Further research revealed that SRSF3 controls the alternative processing of mTOR, a major regulator of cell metabolism, which is essential for heart health.

Researchers discover semiconducting nanotubes that form spontaneously

Scientists have discovered semiconducting nanotubes with precise cylindrical structures, which can be used as fluorescent markers in medical research or catalysts in photoreduction reactions. The researchers' accidental discovery reveals the spontaneous formation of these nanostructures using metallic nanocrystals and certain ligands.

'You all look alike to me' is hard-wired in us, UCR research finds

A new study led by UC Riverside psychologist Brent Hughes found that the tendency to recognize differences in own-race faces is greater than in other-race faces, a phenomenon known as the 'other-race effect.' This bias occurs even at early stages of sensory perception and can affect downstream beliefs and behaviors.

Bacteria associated with hospital infections are found in raw meat

A study by ISGlobal reveals that Acinetobacter bacteria commonly acquired in hospitals can also be transmitted through contaminated food, specifically raw meat. The research analyzed 138 meat samples and identified 12 isolates of the ACB complex, suggesting that raw meat may serve as a reservoir for these pathogenic bacteria.

Study confirms disparities in triple-negative breast cancer diagnoses

A new study published in the Journal of Cancer reveals significant disparities in triple-negative breast cancer diagnoses among women of color and younger women. The research found that non-Hispanic black women had a 2.3-times higher odds of being diagnosed with triple-negative breast cancer compared to non-Hispanic white women.

Ignoring cues for alcohol and fast food is hard -- but is it out of our control?

Researchers have shown that people's general inability to ignore reward cues is not just a lack of control, but rather a limitation of their executive control processes. In an experiment, participants struggled to resist fast food and alcohol cues when under cognitive pressure or high memory load. The findings suggest strengthening exe...

Instability in Antarctic ice projected to make sea level rise rapidly

A study by Georgia Institute of Technology researchers suggests that instability within Antarctic ice will accelerate its flow into the ocean and push sea levels up at a more rapid pace than previously expected. This 'instability' makes forecasting more uncertain, particularly relevant to engineering against flood dangers.
