Formaldehyde is a colorless, flammable, strong-smelling chemical that is used to manufacture building materials and to produce many household products. Formaldehyde sources in the home include pressed-wood products, cigarette smoke, and fuel-burning appliances. When exposed to formaldehyde, some individuals may experience various short-term health effects. Formaldehyde has been classified as a known human carcinogen (cancer-causing substance) by the International Agency for Research on Cancer and as a probable human carcinogen by the U.S. Environmental Protection Agency. Research studies of workers exposed to formaldehyde have suggested an association between formaldehyde exposure and cancers of the nasal sinuses, nasopharynx, and brain, and possibly leukemia.
DNA in preserved museum specimens can allow scientists to explore the history of species and humanities impact on the ecosystem, but samples are typically preserved in formaldehyde which can damage DNA and make it very difficult to recover.
A new study has confirmed that permanent hair dyes and chemical hair straightener use are associated with breast cancers especially among African American women. There have been animal studies that reveal that these hair dyes and chemicals used for straightening the hair are associated with cancers. Human studies however have not shown consistent results establishing the relationship between the chemicals and the cancers.
Although e-cigarettes have been on the market for years, recent reports of vaping-linked illnesses have brought serious attention to these products.
Humans differ from one another in many ways, including how they react to disease, because of their DNA blueprint, as well as the difference in the environments they face. These factors combine to make each person unique. Now a new study published in the journal Nature Protocols reports the development of a promising technology to uncover the process by which the body fights diseases in different ways.
Roughly 85% of recently installed HVAC systems in K-12 classrooms investigated in California did not provide adequate ventilation, according to a study from UC Davis and the Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab).

The smokeless tobacco industry that began with low-voltage cigarette look-alikes has evolved to include customizable, high-wattage machines capable of generating enormous clouds of vapor - and potentially toxic substances.
Researchers at the Israel Institute of Technology have found that children’s mattresses may represent a health hazard as they emit some dangerous pollutants at concerning levels overnight.
When Elyse Imamura's son was an infant, she and her husband, Robert, chose to spread out his vaccinations at a more gradual pace than the official schedule recommended.

E-cigarettes have become increasingly popular as a smoke-free alternative to conventional tobacco cigarettes, but the health effects of "vaping" on humans have been debated in the scientific and tobacco manufacturing communities.
The chemicals present in e-cigarettes can alter DNA in oral cells and increase the risk of cancer, according a new study.
The popularity of electronic cigarettes continues to grow worldwide, as many people view them as a safer alternative to smoking. But the long-term effects of e-cigarette usage, commonly called "vaping," are unknown. Today, researchers report that vaping may modify the genetic material, or DNA, in the oral cells of users, which could increase their cancer risk.
A study by researchers from the Cancer Science Institute of Singapore at the National University of Singapore has revealed that RUNX proteins are integral to efficient DNA repair via the Fanconi Anemia pathway.
