Phys.org / Examining embryo model ethics beyond box-checking
In science, ethical guidelines ensure that research takes place in a way that respects public trust and is conducted responsibly. Traditional ethics approval procedures work well for projects following established practices, ...
Phys.org / Rock bonding changes understanding of earthquake mechanics
When tectonic plates move, they rarely do so smoothly. Sometimes they slide almost imperceptibly; at other times, stress is suddenly released—resulting in an earthquake. What exactly governs this behavior remains one of the ...
Phys.org / High levels of forever chemicals found in Svalbard reindeer
Svalbard reindeer live in a place so remote they have actually evolved to become a subspecies. But that remoteness isn't enough to protect them from contaminants from the industrial world.
Phys.org / From Asgard to Earth: Tiny tubes may reveal the moment complex life began
Stromatolites—and their close relatives, microbial mats—could be mistaken for what seems like a bunch of old dark rocks. But instead, they are dense, layered communities of microbes. Long before complex life such as animals ...
Phys.org / Ancient Māori remains point to largely plant-based diets before colonization
New research led by the University of Otago—Ōtākou Whakaihu Waka, in close partnership with mana whenua, is shedding new light on Māori diet and burial practices in Aotearoa New Zealand prior to European colonization. The ...
Phys.org / New AI method flags fluid flow tipping points before simulations break down
David J. Silvester, a mathematics professor at the University of Manchester, has developed a novel machine-learning method to detect sudden changes in fluid behavior, improving speed and the cost of identifying these instabilities ...
Phys.org / Dragonflies share humans' red-light sensing trick, detecting wavelengths near 720 nm
Sometimes, different organisms can evolve the same ability independently, a process called parallel evolution. A new study from Osaka Metropolitan University (OMU) has found that dragonflies sense red light similarly to mammals, ...
Phys.org / Single-shot imaging captures more information about ultrafast microscopic processes than previously possible
Researchers have developed a new imaging technique that captures more information about ultrafast processes in the microscopic world than was previously possible. The technique offers scientists a powerful new tool to observe ...
Phys.org / What if dark matter came in two states?
The absence of a signal could itself be a signal. This is the idea behind a new study published in the Journal of Cosmology and Astroparticle Physics, which aims to redefine how we search for dark matter, showing that it ...
Phys.org / Why treelines don't simply rise with the climate
A global study by the University of Basel, Switzerland, reveals a surprising picture: While 42% of treelines worldwide are shifting upslope, 25% are retreating. This seemingly contradictory trend involves more than just warming. ...
Phys.org / One DNA letter can trigger complete sex reversal
Researchers at Bar-Ilan University have discovered that changing just one letter in DNA can completely alter sex development in mice. In the new study, published in Nature Communications, a single-letter insertion in a non-coding ...
Phys.org / Houston, we have a problem ... with the toilet
After a successful trip around the moon, everything has been going smoothly on the Orion spacecraft's journey back to Earth—except for the $23 million toilet, which has gotten clogged.
