In this evidence review, researchers identified 17 randomized control trials comparing therapist-supported cognitive behavioural therapy delivered electronically to face to face cognitive behavioural therapy. The studies were conducted between 2003 and 2018 in the United States, Australia, Netherlands, Switzerland, Sweden and the United Kingdom

The precision editing technologies that have revolutionized DNA editing in the cell nucleus have been unable to reach the mitochondrial genome. Now, researchers have broken this barrier with a new type of molecular editor that can make precise C* G-to-T* A nucleotide changes in mitochondrial DNA. The editor, engineered from a bacterial toxin, enables modeling of disease-associated mtDNA mutations, opening the door to a better understanding of genetic changes associated with cancer, aging, and more.

Some animals fake their body size by sounding 'bigger' than they actually are. Researchers studied 164 different mammals and found that animals who lower their voice to sound bigger are often skilled vocalists. Both strategies -- sounding bigger and learning sounds -- are likely driven by sexual selection, and may play a role in explaining the origins of human speech evolution.

Hearing is widely thought to be the last sense to go in the dying process. Now, the first study to investigate hearing in palliative care patients who are close to death provides evidence that some may still be able to hear while in an unresponsive state. Electroencephalography (EEG) was used to measure the dying brain's response to sound. The findings may help family and friends bring comfort to a person in their final moments.

An important line of defense against SARS-CoV-2 is the formation of neutralizing antibodies. These can eliminate the intruders and have great potential to be used for prevention and treatment of SARS-CoV-2 infection. Researchers have elucidated how these antibodies develop and have isolated potent SARS-CoV-2 neutralizing antibodies.
