Loss of large herbivores affects interactions between plants and their natural enemies, study shows
Insects and microorganisms that feed on plants, cut up leaves, modify leaf tissue or produce leaf spots and other kinds of damage, are usually known as pests and considered harmful, yet interactions between plants and their natural enemies are import.....»»
Study sheds light on cancer cell "tug-of-war"
Understanding how cancerous cells spread from a primary tumor is important for any number of reasons, including determining the aggressiveness of the disease itself. The movement of cells into the extracellular matrix (ECM) of neighboring tissue is a.....»»
Why parrots sometimes adopt—or kill—each other"s babies
Infanticide and adoption in the animal kingdom have long puzzled scientists. While both males and females of many species are known to kill the babies of their rivals to secure sexual or social advantage, other animals have been observed caring for t.....»»
Researchers develop bioinspired Bouligand structure for enhanced mechanical properties
Bouligand structures, found in natural materials like fish scales, lobster peritoneum and bones, are known for providing exceptional mechanical properties to biomaterials. While progress has been made in creating bioinspired materials, most research.....»»
Fish residues can compensate for raw materials shortages and improve our health in the bargain
More than a million tons of fish residues can rescue the food and cosmetic industries from raw materials shortages—and create new jobs. The key factors here are oils rich in omega-3, collagen and gelatin......»»
Self-adaptive system for temperature control: A dynamically controllable strategy for healing wound tissue
Skin functions as a sophisticated sensorial system in the human body, capable not only of detecting environmental stimuli—such as temperature, pressure, strain, and vibration—but also of actively responding to these changes. Among these, the temp.....»»
DDT pollutants found in deep sea fish off LA coast raise questions about the pesticide"s continuing threat to wildlife
In the 1940s and 1950s, the ocean off the coast of Los Angeles was a dumping ground for the nation's largest manufacturer of the pesticide DDT—a chemical now known to harm humans and wildlife. Due to the stubborn chemistry of DDT and its toxic brea.....»»
Collecting live snakes in remote Amazon regions for study is no easy task—here"s how we do it
Brazil records an average of 29,000 snakebites a year, leading to around 130 deaths. And it is in the Amazon that the greatest number of cases occur. This region is home to 38 of the 75 species of venomous snakes recorded in Brazil......»»
Researchers develop new AI tool for fast and precise tissue analysis to support drug discovery and diagnostics
A team of scientists from A*STAR's Genome Institute of Singapore (GIS) and Bioinformatics Institute (BII) has developed a new AI software tool called "BANKSY" that automatically recognizes the cell types present in a tissue, such as muscle cells, ner.....»»
Rising mercury levels may contribute to declining Steller sea lion populations
A team of researchers from Texas A&M University and other institutions has made a surprising discovery about rising mercury levels in Steller sea lion pups that may have detrimental effects on the endangered species......»»
Stony coral tissue loss disease is shifting the ecological balance of Caribbean reefs
The outbreak of a deadly disease called stony coral tissue loss disease is destroying susceptible species of coral in the Caribbean while helping other, "weedier" organisms thrive—at least for now—according to a new study published in Science Adv.....»»
Male or female? Scientists discover the genetic mechanism that determines sex development in butterflies
Scientists of the Biology Centre, Czech Academy of Sciences, in collaboration with University of Liverpool have found the genetic mechanism that determines whether individuals of the butterfly species Bicyclus anynana become male or female......»»
