Bacteria Can Defuse Dangerous Chemical In Passaic River

Bacteria that can help defuse highly toxic dioxin in sediments in the Passaic River – a Superfund hazardous waste site – could eventually aid cleanup efforts at other dioxin-contaminated sites around the world, according to Rutgers scientists. Their research, published in the journal Environmental Science & Technology, needs further work to realize the full potential of the beneficial bottom-dwelling microbes.

Evaluating Embryo Quality with Ultrasensitive Protein Detection

Infertility is estimated to affect 9% of reproductive-aged couples globally, and many couples turn to assisted reproductive technology. Selecting embryos with maximum development potential plays a pivotal role in obtaining the highest rate of success in ART treatment.
Researchers can evaluate the quality of an embryo by detecting the content of proteins secreted. In Biomicrofluidics, a method to detect trace proteins secreted by embryos using microfluidic droplets and multicolor fluorescence holds promise to select embryos for ART.

Study suggests marijuana may impair female fertility

Female eggs exposed to THC, the psychoactive ingredient in marijuana, have an impaired ability to produce viable embryos, and are significantly less likely to result in a viable pregnancy, according to an animal study accepted for presentation at ENDO 2020, the Endocrine Society’s annual meeting. The abstract will be published in the Journal of the Endocrine Society.
