Phys.org / Older male humpbacks sire more calves as populations recover from whaling
New research from the University of St Andrews published in Current Biology has shown that the role of age in male humpback whale reproduction has changed as populations recover from centuries of exploitation. Whaling drove ...
Phys.org / InN thin films show transient Pauli blocking for broadband ultrafast optical switching
Recent decades have witnessed rapid advancements in high-intensity laser technology. The combination of laser irradiation and novel materials is opening exciting avenues for the design of functional materials and devices. ...
Phys.org / Curiosity takes its closest look yet at Martian spiderwebs
In this age of Mars rovers, questions about the planet's ancient past have shifted. A growing body of evidence supports the idea that Mars was once warm and wet. Now researchers are focused on the timeline of the red planet's ...
Phys.org / Drug discovery bottleneck? Cell-free platform screens peptides faster, even in harsh conditions
Many biological functions are regulated by the switching on and off of mechanisms triggered by the matching of a keyhole (receptor) formed by a protein's three-dimensional structure and a molecule (ligand) that fits perfectly ...
Phys.org / Cellular switch casts light on why humans are active in the day
Early mammalian ancestors were nocturnal, sleeping during the day while the dinosaurs dominated the land. However, some mammalian lineages, including human ancestors, independently transitioned to diurnality (active during ...
Phys.org / 'Fast-paced, fit, agile': Ableist words in job ads decrease applicants
An office job calls for a "fast-paced, fit and energetic" person who can "stand out" in a crowd. How likely are you to apply? A new University of Guelph study, led by Dr. Melissa Walker as part of her Ph.D., says that more ...
Phys.org / Astronomers inspect ultraluminous X-ray pulsar's magnetic field evolution in the Whale galaxy
Indian astronomers have investigated an ultraluminous X-ray pulsar in the galaxy NGC 4631, designated X-8. The new study, described in a paper published Feb. 16 on the arXiv preprint server, provides essential information ...
Phys.org / Most lab testing quietly inflates 2D transistor performance, research reveals
For nearly two decades, two-dimensional (2D) semiconductors have been studied as a complement or possible successor to silicon transistors, promising smaller, faster and more energy-efficient processors. To ease their production ...
Phys.org / Why crowning the protein that makes jellyfish glow green as a model can help scientists streamline biology
Fruit flies, mice, zebrafish, yeast and the tiny worm C. elegans are model organisms that have carried modern biology on their backs.
Phys.org / Dogs are more like toddlers than cats when it comes to helping humans
Why does your dog rush to "help" when you are searching for something, while your cat seems… eh, less concerned? New research suggests that this difference may stem from deep evolutionary roots—and that, in certain situations, ...
Phys.org / Are climate models detecting monsoon changes a decade too early? 'Super-simulations' say yes
Changes in rainfall within global monsoon regions affect the livelihoods of billions. For years, climate models have suggested that the fingerprint of human-caused climate change on monsoons would become visible by a certain ...
Tech Xplore / Robotic wing inspired by nature delivers leap in underwater stability
Researchers have taken inspiration from nature to create a robotic wing that can sense and adapt to changes in water to deliver unparalleled stability. Drawing on the adaptive movements of birds and fish, the wing senses ...
