Phys.org / Ancient CO₂ surge triggered widespread forest fires and erosion 56 million years ago
The climate warmed up almost as quickly 56 million years ago as it is doing now. When a huge amount of CO2 entered the atmosphere in a short period of time, it led to large-scale forest fires and erosion. Mei Nelissen, Ph.D. ...
Phys.org / Austrian cow shows first case of flexible, multi-purpose tool use in cattle
In 1982, cartoonist Gary Larson published a now-iconic "Far Side" comic titled "Cow Tools." In it, a cow stands proudly beside a jumble of bizarre, useless objects that are "tools" in name only. The joke hinged on a simple ...
Phys.org / Quantum 'alchemy' made feasible with excitons
What if you could create new materials just by shining a light at them? To most, this sounds like science fiction or alchemy, but to physicists investigating the burgeoning field of Floquet engineering, this is the goal. ...
Phys.org / Marine wildlife rarely interact with tidal turbines—and usually avoid collisions when they do, observations show
Tidal turbines harbor the potential to provide a natural, inexhaustible source of power, but have faced some regulatory hurdles and scientific uncertainty about risks to marine life.
Phys.org / A new nanorobot designed to improve immune cell recognition could help treat colorectal cancer
Colorectal cancer, the abnormal growth of cancerous cells in the large intestine or the rectum, is one of the most common types of cancers worldwide. Available treatments for this type of cancer include chemotherapy, radiation ...
Phys.org / X-ray observations reveal hidden disturbances in galaxy cluster Abell 3571
Using the Einstein Probe (EP), astronomers from China and Germany have observed a nearby galaxy cluster known as Abell 3571. Results of the observational campaign, published January 8 on the arXiv pre-print server, provide ...
Phys.org / Physicists uncover hidden magnetic order in the mysterious pseudogap phase
Physicists have uncovered a link between magnetism and a mysterious phase of matter called the pseudogap, which appears in certain quantum materials just above the temperature at which they become superconducting. The findings ...
Phys.org / A shark's energy reserves are linked to how far it travels, suggests new study
For years, researchers have tagged sharks in the world's oceans to learn where they go, how they migrate and where they feed. While these tags have given us a wealth of data about their lives, many questions still remain. ...
Phys.org / Some moral acts matter more than others, study shows
Every day, we quietly judge the people around us. Did that co-worker split the credit fairly? Did a neighbor return a lost package? Did someone cut in line or respect the rules?
Phys.org / First direct evidence of Migdal effect opens new path for dark matter search
In a landmark discovery that bridges nearly a century of theoretical physics, a Chinese research team has successfully captured the first direct evidence of the Migdal effect, a breakthrough with profound implications for ...
Phys.org / AI helps reveal global surge in floating algae
For the first time and with help from artificial intelligence, researchers have conducted a comprehensive study of global floating algae and found that blooms are expanding across the ocean. These trends are likely the result ...
Phys.org / Observing the positronium beam as a quantum matter wave for the first time
One of the discoveries that fundamentally distinguished the emerging field of quantum physics from classical physics was the observation that matter behaves differently at the smallest scales. A key finding was wave-particle ...
