Joslin discovers signs of residual islet cell function in people with long-term type 1 diabetes

...gating whether other factors, such as lifestyle or longevity genes, play a role in the development of complications, reported Dr. Keenan. Overall, the study opens new avenues for research and treatment of type 1 diabetes. "The findings suggest that many patients, even after many years of diabetes, may still h...

Looking to a new era in bee research

...long with mechanistic insights into the remarkable longevity of queen honey bees and sperm stored in the spermatheca. The HBGSP has united a broad range of scientists, from leaders in human genomics and bioinformatics to members of diverse disciplinary and organism-based communities, including those studyi...

Longer-lived rodents have lower levels of thyroid hormone

... explained. "Mice strains that exhibit extended longevity tend to have lower thyroid hormone concentrations than shorter living strains," the authors wrote. "Significant declines in thyroid hormone correlate well with enhanced maximum lifespan." The study compared the levels of these thyroid hormones amo...

Single molecule extends fat mice lives by reversing gene pathways associated with disease in obese

...e activating SIRT1 in mice, as well as other known longevity pathways. How the Study Was Done This study examined three groups of mice, one on a standard diet (SD), another on a high calorie diet (HC) with 60 percent of calories coming from fat, and a third group of mice on the same high calorie diet but...

Researcher examines polymers created with poultry feathers

... structure of keratin can improve the strength and longevity of the polymer. In addition, the viscosity can be improved with reducing agents such as sodium sulfite and lubricants such as poultry fat. The solid-state properties can also be modified using divalent transition metal ions to affect stiffness and sm...

Growth hormone is not the anti-aging bullet for healthy adults

... as bone density, cholesterol levels, stamina, and longevity in this population. "And it's associated with high rates of adverse events. "So, on the basis of available evidence, we cannot recommend growth hormone use for anti-aging in the healthy elderly." Human growth hormone, a protein produced by ...

Researchers identify gene involved in dog size

Whiteflies and plant viruses can help each other to speed up biological invasion

..., the invasive B whitefly had higher fecundity and longevity by 12 and 6 fold when feeding on plants infected by one virus, and by 18 and 7 fold when feeding on plants infected by another virus. Population density of the B whitefly on virus-infected plants reached 2-13 times that on healthy plants in 56 days. ...
