Phys.org / Dragonfly aerial fights follow some simple rules
Dragonflies are renowned for their remarkable flying abilities. Male dragonflies often compete for territory and mating opportunities, engaging in fascinating in-flight battles. Researchers at Imperial College London and ...
Phys.org / Giving bees a probiotic diet could help protect them from extreme temperatures
Honeybees do not like cold weather. When temperatures dip, they can become sluggish and unable to fly. But no matter the conditions in the outside world, they try to keep their hives close to a comfortable 34°C–36°C (93°F–97°F). ...
Phys.org / Detecting the body's magnetic fields with a low-power Ramsey-based magnetometer
Our bodies generate extremely weak magnetic fields as electric currents flow through the heart, brain and other tissues. These signals are used in magnetocardiography and magnetoencephalography to assess heart function and ...
Tech Xplore / Fine-tuned perovskites make blue LEDs more vibrant
Over the past decade, perovskite LEDs have become increasingly vibrant and affordable to produce. With careful tweaks to their chemical composition, these crystal-based light emitters can be tuned across the visible spectrum—matching ...
Medical Xpress / Human study links reduced inflammation to later myopia onset
University of Oklahoma College of Medicine researcher Jody Summers, Ph.D., has long hypothesized that inflammation plays a role in the development of myopia, or nearsightedness, in which close-up vision is clear but distance ...
Phys.org / Gig platforms can simply 'wait out' workers to slash wages, research reveals
Researchers from the Max Planck Institute for Intelligent Systems (MPI-IS), the Tübingen AI Center and Ellis Institute Tübingen have conducted a study that uncovers a mathematical strategy explaining how digital labor platforms ...
Phys.org / Hawaiian stilt reclassified from endangered to threatened after 50 years of conservation efforts
The U.S. Fish and Wildlife Service announced the reclassification of the Aʻeo, or Hawaiian stilt (Himantopus mexicanus knudseni), from endangered to threatened under the Endangered Species Act, a rare and hopeful milestone ...
Phys.org / AI may not make us stupid, but relying on it could weaken the skills built through practice
The worry of becoming stupid isn't new; it dates back to the time of the Greek philosopher Socrates, who insisted that writing would destroy memory and weaken the mind. Then came calculators, GPS and computers, all of which ...
Phys.org / Ancient stone tools reveal complex nomadic lifestyles in Armenian Highlands
A team of international scientists led by Dr. Ariel Malinsky-Buller, together with Ph.D. students David Nora, Ioannis Oikonomou and Dominik Rogall from the Hebrew University of Jerusalem, has uncovered new insights into the ...
Phys.org / Quantum sensing microscope illuminates transistor design
Artificial intelligence faces an energy crisis stemming from a physical traffic jam inside modern computer chips. Processors must continually shuffle data, such as the billions of parameters in complex models, between separate ...
Medical Xpress / New therapeutic target expands options for multiple myeloma
In a phase 1 clinical trial, treatment with the investigational bispecific antibody cevostamab reduced cancer in more than 40% of patients with multiple myeloma, many of whom had already undergone multiple other cancer treatments, ...
Phys.org / Black hole jet may be stirring gas cloud containing early 'red potato' galaxy
A black hole may be stirring a "pot" of gas containing a neighboring galaxy in the early universe, according to a new study published in Astronomy & Astrophysics that used observations from NASA's Chandra X-ray Observatory. ...
