How Cells Clean Up Dead Neighbors — and What It Could Mean for Chronic Inflammation

Leave a Comment / Biology, Cell Biology, Science /

Reading time: 4 minutes Our bodies are constantly repairing and renewing themselves. Every day, cells become damaged, age, or die and need to be removed. It may sound like a simple housekeeping job, but researchers are discovering that this process is surprisingly complex. A new study has revealed how cells in protective tissues can remove […]

Many men experience Y chromosome loss as they age, which may contribute to a shorter lifespan

Biology, Genetics /

As men grow older, they often experience a gradual loss of the Y chromosome from some of their cells. Although the Y chromosome has few genes, its loss has been increasingly linked to serious diseases and shorter lifespan. New methods for detecting Y chromosome genes have revealed that Y loss is common in the tissues

Millions of Your Mother’s Cells Remain Inside You — Scientists Now Know Why

Biology, Genetics /

Every person born on Earth carries a small number of cells that originated from their mother. Roughly one in every million cells in the body may be maternal, meaning we each contain millions of cells that are genetically different from our own. Despite this, the immune system generally accepts them rather than attacking them as

Scientists May Have Discovered a Method to Prolong Fertility in Mice

Biology, Genetics /

As the ovaries grow older, the tissue that supports them gradually becomes stiffer, and researchers believe that slowing this change could help preserve fertility for longer. The area surrounding cells is far from empty. Instead, it resembles a gel-like environment filled with proteins and other molecules that provide structural support and nourishment to the cells.

Study Finds 70% Genetic Overlap Between Schizophrenia and Bipolar Disorder

Biology, Genetics /

Researchers are increasingly discovering that psychiatric disorders that appear very different from one another may actually have overlapping genetic foundations. In February of the previous year, scientists reported that eight separate psychiatric conditions shared common genetic factors. A December follow-up study in Nature became the largest of its kind. Genetic Patterns Across Psychiatric Disorders Researchers

A Little-Known Hair Type Could Help Ease Chronic Itch

Biology, Medicine /

Researchers have identified a previously unknown sensory pathway that connects fine hairs to itch perception, uncovering an unexpected biological mechanism that may play a role in chronic itch disorders and offer new opportunities for treatment. An itch may feel straightforward, but scientists are discovering that the sensation is much more intricate than it seems. Researchers

Researchers unveil a floating buoy engineered to repel jellyfish

Biology, Plants & Animals /

Researchers at the Universitat Politècnica de València and the University of Alicante developed an innovative floating buoy that prevents jellyfish from reaching shorelines, reducing the likelihood of stings for swimmers and beachgoers. The buoy incorporates a range of electronic devices, power systems, and specially designed coils that produce electromagnetic fields. These fields immobilize jellyfish and

Microbial degradation of biodegradable sensors reveals soil dynamics

Biology, Biotechnology /

New degradable sensors may provide valuable insights into the hidden yet vital microbial communities within soil. Developed by researchers at Lancaster University, University of Colorado Boulder, and University of Manchester, the sensors measure biological activity by incorporating a degradable material that soil microbes consume. The sensors have the potential to uncover valuable insights about soil

Research Shows that One Kiss Can Spread 80 Million Bacteria

Biology, Cell Biology /

A Dutch study indicates that just one ten-second kiss may pass on as many as 80 million bacteria. Dutch scientists found that couples who kissed nine times a day were more likely to share saliva bacteria. Previous studies indicate that the human mouth may host over 700 different bacterial species. The new research shows that
