Newborn warty birch caterpillars defend the world’s smallest territory
Peer-Reviewed Publication
At just 1–2mm long, newborn warty birch caterpillars (Falcaria bilineata) are minute, but even though they are tiny they defend the world’s smallest territory: the tip of a birch leaf. They scrape and thump their leaf tip homes to produce vibrations that warn of intruders, but confrontations over their tiny territories never come to blows, protecting both protagonists from injury.
A new form of tumor infiltrating lymphocyte (TIL) therapy, a form of personalized cancer immunotherapy, dramatically improved the treatment’s effectiveness in patients with metastatic gastrointestinal cancers, according to results of a clinical trial led by researchers at the National Institutes of Health (NIH). The findings, published April 1, 2025 in Nature Medicine, offer hope that this therapy could be used to treat a variety of solid tumors, which has so far eluded researchers developing cell-based therapies.
While the threat that microplastics pose to human and ecological health has been richly documented and is well known, nanoplastics, which are smaller than one micrometer (1/50th the thickness of an average human hair), are far more reactive, far more mobile and vastly more capable of crossing biological membranes. Yet, because they are so tiny and so mobile, researchers don’t yet have an accurate understanding of just how toxic these particles are. The first step to understanding the toxicology of nanoplastics is to build a reliable, efficient and flexible tool that can not only quantify their concentration in a given sample, but also analyze which specific plastics that sample contains. An international team of scientists led by the University of Massachusetts Amherst recently announced in Nature Water the development of a new tool, known as the OM-SERS setup, which can do all of these things and can furthermore be used to detect particular nanoplastic concentrations and polymer types in solid samples, such as soils, body tissues and plants.
By integrating powerful 3D imaging technology with advanced computation, University of Arizona researchers can capture gaze direction information from tens of thousands of surface points on the eye instead of about a dozen used by conventional eye-tracking methods. The technique could boost eye-tracking accuracy in a variety of fields ranging from the entertainment industry to medical research and industrial engineering.
Lead, pesticides, brominated flame retardants, plastic additives, polychlorinated biphenyls (PCBs), and heavy metals. This is what researchers at Lund University in Sweden found when they collected dead hedgehogs to investigate the environmental pollutants found in urban environments.
In an era marked by rapid technological advancements, the traditional education system, with its rigid curriculum and prescribed learning paths, is increasingly seen as inadequate for preparing students to embrace the complexities of the modern world. Researchers have identified the tension between prescribed curriculum and student autonomy as the core issue of the educational system. This study analyzes how changes to the prescribed curriculum, pedagogy, and assessments can enhance student autonomy and learning.
Policies around waste management and processing are making global inequalities worse, argues an environmental professor.
Researchers from Tel Aviv University have developed an innovative method that can help to understand better how cells behave in changing biological environments, such as those found within a cancerous tumor.
