Medical Xpress / Macrophages need constant reminders to retain memories of prior infections, researchers discover
Researchers from the University of California, Los Angeles, have discovered that immune cells known as macrophages remain poised to fight repeat infections due to the persistent presence of signaling molecules left behind ...
Phys.org / Tropical forests generate rainfall worth billions, study finds
Tropical forests help to generate vast amounts of rainfall each year, adding weight to arguments for protecting them as water and climate pressures increase, say researchers. A new study led by the University of Leeds has ...
Medical Xpress / Periods may trigger pain for many who have sickle cell disease
Pain related to sickle cell disease (SCD) increases during menstruation, as do emergency department (ED) visits and hospitalizations, for many women and girls—according to a new, nationwide study led by researchers at UC ...
Medical Xpress / Telehealth genetic services increase uptake of counseling in childhood cancer survivors
For childhood cancer survivors, remote telehealth genetic services improve genetic counseling and testing uptake, according to a study published online Feb. 13 in The Lancet Regional Health—Americas.
Tech Xplore / How can you rescue a 'kidnapped' robot? New AI system helps robots regain their sense of location
Mobile robots must continuously estimate their position to navigate autonomously. However, satellite-based navigation systems are not always reliable: signals may degrade near buildings or become unavailable indoors. To operate ...
Phys.org / Plasma rotation simulations could help fusion reactors survive decades of use
Scientists have long seen a puzzling pattern in tokamaks, the doughnut-shaped machines that could one day reliably generate electricity from fusing atoms. When plasma particles escape the core of the magnetic fields that ...
Medical Xpress / Evidence suggests chatbot disclaimers may backfire, strengthening emotional bonds
Concerns that chatbot use can cause mental and physical harm have prompted policies that require AI chatbots to deliver regular or constant reminders that they are not human. In an opinion appearing in Trends in Cognitive ...
Medical Xpress / What a zinc gradient in dentin could mean for fillings and tooth health
Teeth are composites of mineral and protein, with a bulk of bony dentin that is highly porous. This structure allows teeth to be both strong and sensitive. Besides calcium and phosphate, teeth contain trace elements such ...
Phys.org / Specially engineered crystal reveals magnetism with quantum potential
Researchers at the Department of Energy's Oak Ridge National Laboratory, working with international partners, have uncovered surprising behavior in a specially engineered crystal. Composed of tantalum, tungsten and selenium—elements ...
Phys.org / Climbing behaviors of tree-dwelling mammals unlock insights on early primate evolution
Researchers have shed new light on the features that enable tree-dwelling mammals to move effectively through their environments, providing insights into the evolution of the distinct upright postures seen in primates. The ...
Medical Xpress / Big data and human height: Scientists develop algorithm to boost biobank data retrieval and analysis
Extracting and analyzing relevant medical information from large-scale databases such as biobanks poses considerable challenges. To exploit such "big data," attempts have focused on large sampling algorithms that model individual ...
Phys.org / Most roadless areas in Great Britain are smaller than 1 km², fragmenting wildlife habitats
Britain's landscape is highly fragmented by roads, with researchers from Cardiff University finding that more than 70% of the UK's roadless areas are smaller than 1 km2. The researchers say that more than 60% of roadless ...
