Making a good thing better

Researchers have made a breakthrough in understanding liquid electrolytes used in lithium-ion batteries. They found that the actual solvation environment of lithium ions is non-tetrahedral, contrary to previous predictions. This discovery could lead to more efficient and better-performing electrolytes.

Microplastics in the ocean: Biologists study effects on marine animals

A study by biologists at the Alfred Wegener Institute found that ingestion of microplastic particles does not mechanically affect marine isopods. In a feeding experiment, researchers offered isopods artificial food supplemented with plastic particles, which were traced through the digestive system using various microscopy techniques.

Atom-thick CCD could capture images

Researchers at Rice University have developed a two-dimensional, light-sensitive material that can capture images. The material, copper indium selenide (CIS), is highly sensitive to light due to its slow-dissipating electrons, making it 10 times more efficient than previous materials.

Epithelial tube contraction

Scientists at the National University of Singapore identified a novel mechanosensitive regulation of epithelial tube contraction using the C. elegans spermatheca as a model. The study revealed that SPV-1 protein maintains regular cycles of actomyosin contractility, which helps maintain tube integrity.

Hot flashes linked to increased risk of hip fracture

A large cohort study found that women experiencing moderate to severe hot flashes and night sweats have lower bone mineral density and higher rates of hip fracture. Women with these symptoms are more likely to have issues with bone health than their peers, highlighting the need for healthy lifestyle habits to prevent osteoporosis.

Cell-associated HIV mucosal transmission: The neglected pathway

Researchers from Boston University School of Medicine propose that cell-associated HIV transmission is an important element contributing to the HIV epidemic, challenging traditional views on virus transmission. Genetic evidence suggests that HIV-infected cells populate genital secretions and breast milk, providing a new target for HIV ...

Core hospital care team members may surprise you

A study at Loyola University Health System found that social workers, dietitians, and physicians were the most central communicators in a hospital's clinical team. Effective clinical care teams show high degrees of shared cognition, whereas teams working in silos present barriers to optimal patient care.

Time management skills keep animals primed for survival

A new study published in PLOS Computational Biology suggests that animals can make efficient decisions by controlling the amount of effort invested within each unit of time, rather than just speed and accuracy. This ability allows them to adapt to changing environments and gain a fitness advantage over those with limited flexibility.

High socioeconomic status increases discrimination, depression risk in black young adults

A study found that high socioeconomic status, particularly in highly educated families, increases the risk of depression and discrimination among black young adults. Despite parental education's protective effect on white youth, high SES can lead to increased perceptions of being discriminated against, cancelling out its benefits.
