At the droplet of a hat: Capturing mixable liquid interaction

Researchers at OIST Graduate University have successfully captured the spreading of a droplet as it interacts with another mixable liquid for the first time. The study reveals that the droplets spread in a way resembling a 'hat' shape, with the brim continuing to expand over time until fully integrated into the second liquid.

Building a better battery

Researchers have long struggled to understand the factors contributing to battery inefficiency. A new study led by Texas A&M University chemist Sarbajit Banerjee reveals that trapped electrons, which form 'puddles of charge,' are a major obstacle. By imaging these electron clusters using advanced X-ray microscopy, the team has gained i...

Veils, headscarves may improve observers' ability to judge truthfulness, study finds

Researchers found that veils and headscarves can actually improve observers' ability to detect truthfulness in witnesses, contrary to common court assumptions. The study's results suggest that the presence of a veil may compel observers to pay attention to more 'diagnostic' cues, leading to higher accuracy rates in lie detection.

A lesson from fruit flies

Researchers at UC Santa Barbara have discovered a possible first therapy for Mucolipidosis IV by extending their findings from fruit flies to a mouse model. Bone marrow transplantation significantly delayed the onset of motor deficits in MLIV mice, preventing the amplification process that causes neurodegeneration and blindness.

New study shows impact of man-made structures on Louisiana's coastal wetlands

A new study by University of Miami researchers uses satellite data to quantify the impact of man-made canals and levees on Louisiana's coastal wetlands. The study found that these structures limit tidal inundation in 45% of the state's coastline, threatening the ecosystems' ability to adapt to sea-level rise.

Free articles on Aedes albopictus, mosquitoes that may transmit Zika

A special collection of articles from the Journal of Medical Entomology provides in-depth research on Asian tiger mosquito, Aedes albopictus, including its introduction to North America, disease transmission, and control measures. The studies highlight the importance of understanding this invasive insect for effective mosquito management.

Vegetation in Russian Arctic has memory

Researchers found that the degree of cold in the preceding ice age determines how fast vegetation adapts to interglacial climates. The study reveals that plants need thousands of years to adapt from a cold to a warmer period, with permafrost being the main reason for this delay.

Lives in the balance: Why do we hold onto potentially harmful, disease-causing mutations?

A recent study found that balancing selection can increase the frequency of harmful mutations in non-HLA genes within the MHC region. This mechanism may contribute to the prevalence of heritable diseases. The research team used DNA sequencing data from 6,500 individuals to test this hypothesis.

Researchers find human development's first gear

A team of researchers at Oxford University has identified four genes that play a crucial role in early human development. These genes, known as Argfx, Leutx, Dprx and Tprx, are activated for an extremely brief period, when the embryo is a tiny ball of 8-16 cells. They then switch off, controlling the 'first gear' of embryonic growth.
