Does anemia during pregnancy affect newborns’ risk of heart defects?

Researchers discovered that mothers who are anemic in early pregnancy have a 47% increased likelihood of giving birth to a child with congenital heart disease. This finding suggests that widespread iron supplementation could help prevent congenital heart disease in many newborns before it develops.

Bacteria killing material creates superbug busting paint

A new paint with a built-in bacteria-killing agent has been found to effectively kill MRSA, flu and COVID-19 on various surfaces. The paint, developed by scientists at the University of Nottingham, uses chlorhexidine to create an antimicrobial coating that can be applied to plastic and hard non-porous surfaces.

TOS statement on oral GLP-1s

A new oral small molecule glucagon-like peptide-1 (GLP-1) receptor agonist, Orforglipron, has demonstrated significant weight loss of 7.9% in individuals with diabetes and impaired glycemic control. The safety and tolerability of the medication are consistent with injectable therapies, making it a potentially accessible treatment option.

Big brains and big ranges might not save birds from climate change

A new study found that some bird species with large geographic ranges and big brains are actually more susceptible to climate change than previously thought. Researchers analyzed data from citizen scientists and found that birds adapted to narrow climate niches, such as the Arctic, are at higher risk from climate change.

Predicting long-term psychedelic side-effects

Researchers surveyed 654 people who planned to take psychedelics, finding a weak correlation between lifetime psychedelic use and delusional ideation. The study suggests that schizotypal traits may not be caused by taking psychedelics, with only 1/3 of participants experiencing lingering hallucinatory sensory experiences after four weeks.
