North American birds not fully adjusting to changing climate

At least 30 out of 114 North American bird species have become less well-adjusted to their climate over the last 30 years, according to a recent study. Climate decoupling, where species distributions and abundances diverge from climate conditions, is particularly prominent among habitat specialists.

A new treatment approach for cystic fibrosis

A new treatment approach using antisense oligonucleotides (ASOs) may help reduce cystic fibrosis symptoms and improve quality of life for patients with a specific gene mutation. The ASO strategy tricks cells into making an imperfect but functional version of the CFTR protein, which is better than having none at all.
