ECHA Bans Harmful Chemicals in Gel Nails; Parabens' Transgenerational Effects Revealed
The European Chemicals Agency (ECHA) has led a push for stricter regulations on harmful chemicals in gel nail products, with a ban on substances like formaldehyde and toluene effective since January 2021. Meanwhile, a new study published in Nature sheds light on the transgenerational effects of parabens on mice. In the realm of academia, a study on degree attainment in various disciplines has revealed interesting trends in chemistry and biology majors.
In a significant move to protect consumers, the ECHA, backed by EU national chemical agencies, has implemented new regulations restricting harmful chemicals in gel nail products. This comes after extensive scientific assessment and public consultations. The ban, effective since January 2021, targets chemicals like formaldehyde and toluene, which are known to pose health risks.
In the field of chemistry research, a new study published in Nature has uncovered concerning transgenerational effects of parabens. The study found that prenatal exposure to propylparaben in mice can lead to diminished ovarian reserve in future generations. This discovery highlights the potential long-term impacts of chemical exposure.
A recent study on degree attainment in various disciplines has provided insights into the trends among chemistry and biology majors. While there has been a small increase in both BS and PhD degree attainment in chemistry, the growth is notably slower compared to biological sciences. This suggests that some students might be switching their majors from chemistry to biology. The author's observations also indicate that pre-med undergraduates perceive the environment in biology departments as more appealing, contributing to this shift.
The author's research, freely available at doi.org/10.1021/scimeetings.5c11304, provides a comprehensive look at these trends. The author's interest in statistics was sparked by discussions with Rebecca Trager about the changing status of chemistry departments in the UK and US.
The ECHA's ban on harmful chemicals in gel nail products marks a significant step in consumer protection. Meanwhile, the Nature study on parabens underscores the need for further research into the long-term effects of chemical exposure. In academia, the trends in chemistry and biology majors highlight the importance of understanding student perceptions and preferences in shaping educational policies.
