Human preimplantation embryos based on their chromosomal status. Left: euploid, no errors. Middle: aneuploid (abnormal). Right: a mitotic error leads to chromosomal mosaicism. The embryo may harbor both euploid and abnormal cells.

Here’s the bird’s eye view on science this week:

Mental health effects of child maltreatment may surface later in life

Maltreatment during childhood increases the risk of diagnosis with a mental health disorder after the age of 38, even without a prior history of mental health disorders, researchers have found. Read full Digest >>>

More hope for would-be parents? Many embryos ruled out in IVF “self-correct”

Some ‘faulty’ embryos that are normally discarded in IVF can self-correct in the womb and result in healthy pregnancies. So-called ‘aneuploid embryos’ are flagged up in a genetic test before implantation. The finding could improve women’s chances of having healthy pregnancies. Read full Digest >>>

Cancer Gone Viral: The road from pain to liver cancer… and the cure

In this installment of our Cancer Gone Viral series, we talk about the Hepatitis C virus (HCV), the poster child of the opioid epidemic. It’s responsible for causing liver cancer but luckily, there’s a cure… if you catch it in time. Read full Digest >>>

Good news or bad? Climate change cuts insect numbers on farmlands

Intensive agriculture farmlands most impacted by climate change have seen a major decline in insects — a new study has found. This matters because insects are not just a nuisance but pollinators and important parts of the food chain. Read full Digest >>>

Cancer Gone Viral: How HIV infection ramps up cancer risk

Human Immunodeficiency Virus (HIV) is one of the most notorious cancer-causing viruses… which –weirdly– messes with our immune system and makes us more susceptible to other cancer-causing viruses. Read full Digest >>>
