The SynergyAge Database: Which Genetic Effects on Life Span are Additive?

The SynergyAge database is intended to collect information on interactions between longevity-related mutations. Many such genetic alterations have been studied in laboratory species – yeast, flies, worms, mice, and so forth – but interactions between mutations are only sparsely investigated in comparison. This is true for all interventions in aging, as a rule. The scientific […]

TAU study finds “environmentally-friendly” disposable tableware has negative effects on marine animals

A new Tel Aviv University study compares the effects of two types of disposable dishes on the marine environment — regular plastic disposable dishes and more expensive bioplastic disposable dishes certified by various international organizations — and determines that the bioplastic dishes had a similar effect on marine animals as regular plastic dishes. Moreover, the study finds […]

Estrogenic and anti-estrogenic effects of PFASs could depend on the presence of estrogen

Perfluoroalkyl substances (PFASs) have received intense scrutiny in recent years because of their persistence in the environment and potential endocrine-disrupting effects. However, their estrogenic activities are controversial, with different studies showing apparently contradictory results. Now, researchers reporting in ACS’ Environmental Science & Technology have used a combination of laboratory experiments and computer modeling to reveal that PFASs […]

University of Iowa chemists study environmental safety, health effects of nanotechnology

The world of nanotechnology is a place where materials so small they’re undetectable to the human eye are found in products we use every day, from sunscreen to cell phone batteries. That’s a good thing. But nanomaterials may have hazardous side effects to the environment or to human health. And because these constituents are so tiny, […]

Immune Protein IL-17A Responsible for Lethal Side Effects of Gastric Cancer

The formation of scar tissue, or fibrosis, as gastric cancer disseminates throughout the peritoneum can be more lethal than the cancer itself and can interfere with chemotherapy. Researchers from Kanazawa University have now found that proinflammatory cytokine IL-17A from mast cells heavily influences the degree of fibrosis and causes structural changes in peritoneal cells. Preventing […]
