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 […]
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

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.

A new cancer drug could help block both tumor growth and the spread of aggressive prostate cancer, according to a study by researchers at Umeå University and international collaborators, published in the journal Signal Transduction and Targeted Therapy. Researchers developed the new drug to stop cancer from spreading. According to Maréne Landström, who led the

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

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 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

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

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
Research Shows that One Kiss Can Spread 80 Million Bacteria Read More »
A recent imaging study questions long-held beliefs about how hair grows and may open the door to new hair-loss treatments. Scientists have found that human hair doesn’t grow by being pushed up from the root. Rather, it is drawn along by forces from a newly identified network of moving cells. This discovery challenges long-standing biological
