Even birds can't outfly climate change

As rising global temperatures alter ecosystems worldwide, animal species usually have two choices: adapt to changing local conditions or flee to a cooler clime. Ecologists have long assumed that the world's bird species were best equipped to respond to the pressures of climate change simply because they have the option of flying to higher altitudes or towards global poles. But a new study finds that few bird species are able to escape the realities of a warming world.

New factor linked to heart failure

When the workload on the heart increases, the ventricular wall may thicken too, known as cardiac hypertrophy. This is an adaptive response that reduces pressure on the heart and maintains the activity of this vital organ. It is often a reversible process that does not cause serious effects on the structure or function of the heart, but if the factor causing cardiac overload becomes chronic, it can lead to pathological hypertrophy with more serious effects (dilatation of the ventricular cavities, alterations in cardiac function, heart failure, etc.).

Fat-rich fluid fuels immune failure in ovarian cancer

New research has uncovered how lipid-rich fluid in the abdomen, known as ascites, plays a central role in weakening the body's immune response in advanced ovarian cancer. The findings offer new insights into immune suppression in ovarian cancer and open promising avenues for future immunotherapy approaches. Over 70% of patients with ovarian cancer are diagnosed at an advanced stage, often presenting with large volumes of ascites. This ascites fluid not only supports the spread of cancer throughout the abdominal cavity but also significantly impairs the body's immune defenses. Understanding how ascites affects the immune system is important for developing better treatments that use the immune system to fight cancer.

Cracking the code: Deciphering how concrete can heal itself

Lichen is an understated presence in our everyday world, often found clinging to trees and rocks. Its true beauty lies in its unique symbiotic system of fungi and algae, or cyanobacteria, that form a self-sustaining partnership, allowing it to thrive in even the harshest conditions. With that inspiration, researchers created a synthetic lichen system that collaborates like natural lichens. Their system uses cyanobacteria, which turns air and sunlight into food, and filamentous fungi, which produces minerals that seal the cracks. Working together, these microbes survive on nothing more than air, light and water. The autonomy of this system sets it apart from previous self-healing concrete endeavors.
