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.
A team of international scientists has recently developed virus-like particles (VLPs) by coating liposomes with the synthetic spike glycoprotein of SARS-CoV-2.
Scientists with the Desert Research Institute Organic Analytical Laboratory in Reno, Nev., led by Andrey Khlystov, Ph.D., have been awarded a $1.5M grant from the National Institutes of Health (NIH) to study the formation of dangerous compounds by electronic cigarettes (e-cigarettes).
Despite tremendous efforts by the global scientific community to curb the spread of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), by developing more efficient testing protocols, therapies, and vaccines at a rapid pace, relatively little is known about the dynamics of SARS-CoV-2 replication within cells.
New research published today indicates that BAT's modern oral (MO) products in the form of tobacco-free nicotine pouches have a toxicant profile that is comparable to nicotine replacement therapies (NRTs) and much lower than traditional oral snus, a category of products that, when used as the sole nicotine product is already established as a reduced risk product compared with cigarettes.
When we inhale isolated coronavirus particles, more than 65% reach the deepest region of our lungs where damage to cells can lead to low blood oxygen levels, new research has discovered, and more of these aerosols reach the right lung than the left.
Vaccines are currently a great source of hope for many people, as it is believed they will help to protect society against COVID-19 and pave the way back to a normal life. The current focus is clearly on coronavirus — but vaccines are also fundamental to combating other pathogens.
Just as e-cigarette ingredients can vary from one region to another, the health effects of vaping can have regional characteristics as well. A new study out of West Virginia University suggests that rural e-cigarette users are older--and often get sicker--than their urban counterparts.
San Francisco restaurant owners, already simmering over covid-19 restrictions, are ready to boil over because of a city ban on natural gas stoves in new buildings that takes effect in June.
UiO's IONICON PTR-MS laboratory tracks the impact of toxic organic gases.
A new study finds that California's commuters are likely inhaling chemicals at levels that increase the risk for cancer and birth defects.
A person breathes in approx. 20 kilos of air every day. In Denmark, we spend almost 90 per cent of our time indoors, and therefore the chemical indoor climate in our buildings has a major impact on our health.
Researchers in the UK and the United States have developed a stem-cell-based screening platform for identifying compounds that inhibit infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) – the causative agent for coronavirus disease 2019 (COVID-19).
Rice is the staple food of about half the world's population. The cultivation of the rice plant is very water-intensive and, according to the German aid organization Welthungerhilfe, around 15 per cent of rice is grown in areas with a high risk of drought.
A toxic chemical ban signed into law in California will change the composition of cosmetics, shampoos, hair straighteners and other personal care products used by consumers across the country, industry officials and activists say.
A University of Cincinnati immunologist is recommending that individuals with contact dermatitis choose facial masks made without elastic or rubber that allow them to stay safe in the midst of COVID-19 while avoiding possible allergic reactions.
Researchers at the University of Maryland School of Medicine (UMSOM) have developed a novel technology to test for the presence of thin membrane protrusions called "microtentacles" on breast cancer cells, which can help predict whether a tumor is likely to spread.
A well-known hangover drug not only helps soothe pounding headaches but also triggers profound changes that protect the liver, USC scientists report in new findings that could help prevent alcohol-related harm.
A well-known hangover drug not only helps soothe pounding headaches but also triggers profound changes that protect the liver.
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.
