Phys.org / More dives, fewer reef sharks: Caribbean study links tourism pressure to shark sightings
Reef sharks are observed less frequently on Caribbean reefs that have high levels of diving activity and greater coastal development, according to new research published in the Journal of Applied Ecology. Even recreational ...
Phys.org / Stitching precise patterns—with lasers
Just as embroiderers, with needle and thread, can transform plain fabric into an intricate pattern, engineers can use lasers and polymers to create flexible, complex structures that could transform life-saving sensing technology. ...
Phys.org / Cell 'snowball' may be answer to large-scale tissue engineering
Cell cultures—single layers of cells grown in a small dish—have enabled researchers to study biological growth, develop or test drugs and even discover what causes some diseases. Cell spheroids, 3D versions of cell cultures ...
Phys.org / Origins of Earth's most powerful ocean current revealed
It transports far more than 100 times as much water as all of the Earth's rivers combined: The Antarctic Circumpolar Current rushes around the southern continent unhindered by land masses and is therefore a fundamental component ...
Phys.org / Body size, lifespan and mobility can help predict which species are most threatened as planet changes
How can we predict species' responses to always-arising changes in our world? A long-term ecological study from Yokohama National University researchers suggests the answer may lie in a few small simple biological traits. ...
Phys.org / Pigeons tend to respond 'at the edge of chaos,' study finds
If you were rewarded for following a particular pattern of behavior, wouldn't you keep doing it? The answer turns out to be more nuanced than you might think. In a new study, University of Iowa researchers report that pigeons ...
Phys.org / Spring cold snaps harm nesting tree swallows, but some show resilience
Warming temperatures from climate change cause tree swallows to nest up to two weeks earlier than they did in the 1970s, but early spring cold snaps can hinder nestlings' growth and survival, according to a new study that ...
Phys.org / Scientists identify potential new target for disrupting mosquito reproduction
A longstanding mystery in mosquito biology has been solved, opening a potential new path for controlling mosquitoes and the diseases they spread. For decades, scientists believed that juvenile hormone, a chemical signal essential ...
Phys.org / Quantum ground state of rotation achieved for the first time in two dimensions
Quantum mechanics tells us that a particle can never be perfectly still. But how precisely can it be oriented? A research team at the University of Vienna, together with colleagues at TU Wien and Ulm University, has now cooled ...
Phys.org / Rating community resilience with a deep learning framework
An understanding of community resilience and risk analysis is vital when it comes to protecting civilians and infrastructure from natural hazards, such as hurricanes or earthquakes. Artificial intelligence is an efficient ...
Phys.org / Robotic floats uncover hidden ocean chemistry in low-oxygen zones
Scientists have found a new way to detect subtle chemical signatures in seawater, revealing previously invisible details about the ocean's chemistry from data continuously collected by thousands of autonomous robotic floats ...
Phys.org / Expanded MAGIC toolkit makes genome-wide single-cell mosaic analysis possible in Drosophila
Researchers at Cornell University have developed a powerful new genetic toolkit that allows scientists to study how genes function at the level of individual cells, an advance that could accelerate discoveries in development, ...
