Charge radii of exotic potassium isotopes challenge nuclear structure theory

Researchers from University of Jyväskylä studied nuclear charge radii of exotic potassium isotopes using collinear resonance ionization spectroscopy. The results showed that the potassium isotope with a neutron number of 32 does not conform to magic neutron number criteria, challenging current understanding of nuclear forces.

Deforestation is stressing mammals out

Researchers found higher levels of glucocorticoid stress hormones in animals from smaller forest patches, indicating chronic stress. The study highlights the impact of habitat destruction on wildlife, particularly in fragmented landscapes.

In vitro study helps explain how Zika virus passes from mother to fetus during pregnancy

A new study by USF Health researchers has discovered that maternal decidual cells act as reservoirs for Zika virus transmission through the placenta. The study also found that tizoxanide can effectively inhibit Zika virus in these cells, offering promise for preventing perinatal transmission and its associated health problems.

Computerized adaptive screener may help identify youth at risk for suicide

A new computerized adaptive screener has been developed to identify youth at risk for attempting suicide, correctly identifying 82.4% of youth who went on to attempt suicide in the three months following screening. The screener, CASSY, offers an easy-to-use way for providers to detect youth suicide risk in emergency department settings.

Research indicates gender disparity in academic achievement and leadership positions

A recent study discovered a significant gap in leadership opportunities for women, particularly mothers, who demonstrate high academic achievement. Despite having similar leadership prospects as fathers with low GPAs, women face barriers in securing promotions due to factors such as household responsibilities and biased promotion pract...

Research looks at the link between procedures and everyday practice in community pharmacy

A recent study published in Applied Ergonomics compared standardized processes for community pharmacists with their real-world practices, revealing a significant gap. The researchers identified four main themes: efficiency, resource availability, thoroughness, and delegating safeguards. Further research is needed to adapt procedures to...

Blink! The link between aerobic fitness and cognition

A study from the University of Tsukuba found that higher spontaneous eye blink rates correlate with improved cognitive function and enhanced executive function in physically fit individuals. The dopaminergic system, involved in physical activity and exercise, plays a crucial role in mediating this link.

Uncovering recurring deletions in SARS-CoV-2 spike protein that drive antibody escape

Researchers identified recurring deletions in SARS-CoV-2 spike protein that prevent antibody binding, allowing viruses to evade the immune system. The study analyzed nearly 150,000 gene sequences and found instances of viruses with these deletions, which have repeatedly arisen in genetically distinct viruses worldwide.

CABI study updates safer options for fall armyworm control in Africa

A recent CABI study has updated the list of potential biopesticide active ingredients for managing fall armyworm in Africa, with 41 products now registered across 30 countries. The review highlights the efficacy of eight additional biological control agents, including Aspergillus oryzae and thyme oil.
