Sweet Deception: How Mycobacteria Exploit Immune Receptors to Survive
A new study reveals that Mycobacterium tuberculosis can dodge the host’s immune defenses by targeting an innate pattern recognition receptor on macrophages.
This interaction helps promote the mycobacteria’s ability to survive within the host cells.

A sugar on mycobacteria binds to the immune receptor dectin-1 on host macrophages, helping the bacteria survive and driving susceptibility to infection.
Direct evidence for poison use on microlithic arrowheads in Southern Africa at 60,000 years ago
Hunter-gatherers in southern Africa laced their stone arrow tips with poison roughly 60,000 years ago, a new Science Advances study finds.
The discovery pushes back the timeline for poison weapon use from the mid-Holocene to the Late Pleistocene.
Earliest proof of plant poisons on arrows reveals complex Pleistocene hunting in southern Africa.
Loss of Lipin1 Contributes to Multiple Pathological Processes in the Development of Heart Failure
Loss of lipin1 disrupts heart muscle membrane integrity, driving inflammation, fibrosis, and contributing to heart failure.
BackgroundLipin1 has dual functions acting as phosphatidic acid phosphatase required for lipid synthesis and as a transcriptional coactivator. Our previous research demonstrated that lipin1 is critical for maintaining sarcolemmal integrity in skeletal muscle. Given the importance of sarcolemmal stability for cardiac muscle viability and function, we investigated the role of lipin1 in the heart using a novel cardiac‐specific lipin1 deficient (Myh6‐lipin 1−/−) mouse model.
Scientists Made a Flash of Light Disappear Inside a Liquid
Liquids and solutions may look simple, but on the molecular scale they are constantly shifting and reorganizing. When sugar dissolves in water, each sugar molecule quickly becomes surrounded by fast moving water molecules. Inside living cells, the situation is even more intricate. Tiny liquid drople
Gravity May Be Key Evidence That Our Universe Is a Simulation, Groundbreaking New Research Suggests
One of nature’s most familiar forces might be doing something far stranger than we ever imagined.
