An international study led by Adelaide University has found bowhead whale populations are recovering only in stocks where large areas of hazardous sea ice conditions limited devastating hunting centuries ago. The research ...

Materials called relaxor ferroelectrics have been used for decades in technologies like ultrasounds, microphones, and sonar systems. Their unique properties come from their atomic structure, but that structure has stubbornly ...

For nearly 25 years, scientists believed they knew what caused the most severe form of narcolepsy. A new UCLA Health study now suggests they were only half correct. In a study published in Nature Communications, UCLA Health ...

During the early stages of a pandemic, viruses tend to evolve in ways that enhance their ability to reproduce and spread, rather than to evade the host's immune system. The genetics and sex of the host influence how a novel ...

Anyone who has ever used a microscope knows that it takes time to bring a sample into sharp focus. Each time you move the slide, the image blurs, and you have to stop and carefully turn a knob to bring everything back into ...

Every stroke begins with a sudden interruption of blood flow in the brain. But what happens afterward—why neurons continue to lose function and die over the following days—has remained one of the most important unanswered ...

An AI model (REDMOD) can pick up the very early subtle tissue changes of pancreatic ductal adenocarcinoma, the most common form of pancreatic cancer, which conventional imaging and the human eye find difficult to detect, ...

As devices for wireless sensing systems become smaller and more complex, finding suitable power sources for them is becoming increasingly difficult. However, advances in low-power sensing technology may allow such systems ...

Every cell in the human body squeezes over six feet of DNA into a minuscule speck invisible to the naked eye—like compressing a whole house into a single sugar cube. In order to fit in a cell and remain organized, DNA is ...

Under a microscope, a bouquet of lollipop-like structures, each smaller than a grain of sand, waves gently in a Petri dish of liquid. Suddenly, they snap together, like the jaws of a Venus flytrap, as a scientist waves a ...

After a heart attack, the body rapidly floods the injured heart with neutrophils—white blood cells that help repair damage but can also make it worse when too many arrive too quickly. New research from the University of Oklahoma ...

After nearly four decades, the world's longest-running soil warming experiment is revealing a surprising result: even "stable" carbon in forest soils can break down as temperatures rise, releasing more CO₂ into the atmosphere. ...
