Research finds new evidence about the mechanisms controlling skin repair and regeneration As the air continues to dry and temperatures drop, the yearly battle against dry hands and skin has officially begun. New research from Northwestern University has found new evidence deep within the skin about the mechanisms controlling skin repair and renewal. Skin's barrier function gives it the unique ability to fight winter woes and retain water for our bodies. The outer layer of the skin, the epidermis, is constantly turning over to replace dead or damaged cells, creating new cells to reinforce the ...

New cancer models mimic aspects of mechanical environment within the body As cancer and tumor cells move inside the human body, they impart and are subject to mechanical forces. In order to understand how these actions affect cancer cell growth, spread, and invasion, a team of engineers at Rensselaer Polytechnic Institute is developing new models that mimic aspects of the mechanical environment within the body, providing new insight into how and why tumors develop in certain ways. In research published today in Integrative Biology, a team of engineers from Rensselaer developed an in vitro --...

Researchers are merging artificial intelligence (AI) and the latest computer technology with biological know-how to identify insects that possess supernatural speed.

Researchers uncover key regulation step that inhibits tumor growth Most living things need oxygen to grow and thrive. Even cancerous tumors. That's why tumors will readily sprout new blood vessels if their oxygen is starved, creating new lifelines for survival. A study published today from Scripps Research pinpoints the precise molecular machinery that makes this happen, providing scientific insights that can potentially be translated into medicines that help kill tumors and stop cancer from spreading in the body. The findings also may enable new interventions that promote healthy blood-vesse...

Brain tissue analysis may help explain enduring mysteries about PTSD A post-mortem analysis of brain tissue from people who had been diagnosed with post-traumatic stress disorder (PTSD) may help explain enduring mysteries about the disorder, such as why women are more susceptible to it and whether a dampened immune system response plays a role in dealing with stress, a team headed by Yale University researchers has found. The analysis of gene expression patterns in brain tissue located in four regions of the prefrontal cortex -- areas of the brain associated with higher cognitive function and...
