How a male fly knows when to make a move on a mate

Researchers found that male fruit flies adjust their scent sensitivity by altering a gene called fruitless in response to pheromone signals and social environment. This study may provide insights into treating sensory processing disorders like autism, as it reveals how organisms selectively tune into or block sensory input.

First fossil nursery of the great white shark discovered

Researchers analyzed 2-5 million year old fossil teeth to reconstruct body size distribution patterns of the great white shark in the past. The discovery reveals a significant nursery area with high percentages of young sharks, indicating that environmental changes can impact population dynamics and evolutionary success.

ALMA spots twinkling heart of Milky Way

Astronomers using ALMA have spotted quasi-periodic flickers in millimeter-waves from the center of the Milky Way, suggesting a rotating radio spot circling a supermassive black hole. The findings provide insight into space-time with extreme gravity and may shed light on the behavior of gas around the black hole.

Combinatorial screening approach opens path to better-quality joint cartilage

A collaborative research team has developed a multi-component biomaterial-based screening approach that identifies material compositions and mechanical stimuli enabling human stem cells to differentiate into cells capable of generating higher-quality articular cartilage. The study uses high-throughput screening with multiple combinatio...

Algal genome provides insights into first land plants

The Penium margaritaceum genome provides insights into the origins of land plants by revealing footprints of adaptations for UV radiation protection and cell wall structure. The genome contains genes involved in regulatory systems, hormone signaling, and mucilage production, which are essential for structural support.

How the darter got stripes: Expanding a sexual selection theory explains animal patterns

A study led by University of Maryland Baltimore County Ph.D. candidate Samuel Hulse demonstrates a strong correlation between the visual patterns on male darter fish and their environments, supporting sensory drive theory. The findings show that male fish with colors easily perceivable in their environment are more likely to reproduce.

Cell reproduction dogma challenged

Researchers from CNRS and IGBMC demonstrate that meiosis in mice begins and proceeds normally even without retinoic acid. Meiosis is a crucial process for the transmission of unique sets of genes to offspring, resulting in novel assortments of chromosomes.

'Time is vision' after a stroke

Stroke survivors who receive early visual training can recover more of their lost vision than those trained later. Researchers discovered that the brain's visual structures degenerate over time after an occipital stroke, but early intervention can halt this loss.

Blood flow recovers faster than brain in micro strokes

A Rice University study reveals that blood flow to the brain recovers faster than brain function after a microstroke. The research used advanced neural monitoring technology to measure both blood flow and neuronal recovery simultaneously, showing a significant disconnect between the two processes.
