Credit: CC0 Public Domain MIT cancer biologists have discovered a new mechanism that lung tumors exploit to promote their own survival: These tumors alter bacterial populations within the lung, provoking the immune system to create an inflammatory environment that in turn helps the tumor cells to thrive. In mice that were genetically programmed to develop […]Continue Reading ...
Jan 22 2019 Mice growing up in a basic cage maintain lifelong visual cortex plasticity if their parents were raised in an environment that promoted social interaction and physical and mental stimulation, according to a multigenerational study published in eNeuro. The research suggests life experience may be transmitted from one generation to the next through […]Continue Reading ...
Nurse gives injection to woman, New Orleans, 1941. Credit: Wikipedia. Scientists increasingly believe that one of the driving forces in chronic pain—the number one health problem in both prevalence and burden—appears to be the memory of earlier pain. Research published today/this week in Current Biology suggests that there may be variations, based on sex, in […]Continue Reading ...
In ‘game-changing’ finding, bone mass rose 800% after signals were blocked in brains of mice UCLA and UC San Francisco life scientists have discovered a dramatic pattern of bone growth in female mice — research that could potentially lead to stronger bone density in women and new treatments for osteoporosis in older women. The researchers […]Continue Reading ...
Buck researchers also harness an innate repair mechanism to protect against liver damage in aging mice and extend lifespan in flies Older mice who are surgically joined with young mice in order to share a common bloodstream get stronger and healthier, making parabiosis one of the hottest topics in age research. Publishing in Nature Metabolism, […]Continue Reading ...
Genetically engineered mice mimic common sleep problems Mice that sleep fitfully could help researchers unravel the mystery of insomnia. Researchers at Washington University School of Medicine in St. Louis studied mice genetically modified to mimic the genetic disease neurofibromatosis type 1 (NF1), which is associated with sleep problems. They found that the animals, like some […]Continue Reading ...
If only we could keep our bodies young, healthy and energetic, even as we attain the wisdom of our years. New research at the Weizmann Institute of Science suggests this dream could be at least partly obtainable in the future. The results of this research, led by Prof. Valery Krizhanovsky and Dr. Yossi Ovadya in […]Continue Reading ...
Mice with AD-like symptoms receiving supplemental levels of choline in the womb improved their spatial memory. A second generation bred from these choline-treated mice also showed improved spatial memory, suggesting epigenetic changes in genes. Choline acts to reduce harmful levels of the amino acid homocysteine, converting it to the beneficial chemical methionine. Credit: Shireen DoolingBiodesign […]Continue Reading ...
miR-146b knockout (KO) mice developed hematopoietic malignancy. Credit: Department of Systems BioMedicine,TMDU The abnormal expression of different classes of molecules is known to be linked to various types of cells becoming cancerous. This is also true for the recently discovered group of small, noncoding molecules called microRNAs (miRNAs), although much remains to be investigated about […]Continue Reading ...
Most neurons in the human brain are generated from neural stem cells during embryonic development. After birth, a small reservoir of stem cells remains in the brain that keeps on producing new neurons throughout life. However, the question arises as to whether these new neurons really support brain function? And if so, can we improve […]Continue Reading ...
Cocaine is a highly addictive psychostimulant that induces complex molecular, cellular and behavioral responses. Despite various approaches and years of pre-clinical studies, effective, mechanism-based therapies to assist with cocaine misuse and dependence are still sorely lacking. Although it is well understood that elevations of the brain chemical dopamine play a critical role in cocaine’s ability […]Continue Reading ...
Russian neuroscientists discovered that the stress experienced by mice during their first weeks of life, affects not only them but also their offspring. The obtained data will help to understand how negative experience in the early period of life affects the mammalian brain. The results are published in Genes, Brain and Behavior. Separation from mother […]Continue Reading ...
MONDAY, Jan. 7, 2019 (American Heart Association) — A new study suggests that high levels of inorganic phosphate — a preservative widely used in certain sodas, packaged meats and other processed foods — may be a reason why the U.S. population isn’t as physically active as it used to be. Researchers from UT Southwestern Medical […]Continue Reading ...
In a new study, researchers have shown that obesity increases the level of semi-dormant senescent cells in the brain, which give rise to anxiety-like behaviors. Illustration Forest | Shutterstock Obesity is a growing global health problem; current estimates suggest that about a fifth of the adult population worldwide will be obese by 2025. It is […]Continue Reading ...
