Gene editing with CRISPR can cause off-target mutations, but this seems to happen less often with an enzyme that cuts one of the strands of DNA instead of both.

Genetically modified pig hearts transplanted into two more patients
The team of researchers who transplanted a genetically modified pigโs heart into a living human earlier this year have completed two more pig heart transplant surgeries, setting the protocol for such operations.
In January this year, 57-year-old David Bennett became the first man on the planet to receive a heart from a genetically modified pig. Before this, researchers transplanted kidneys from similarly modified pigs into patients that were brain dead.
The organs are sourced from a company called Revivicor which uses genetic engineering to remove specific genes in the pigs to help in reducing transplant rejection while adding some that make the organs more compatible with the human immune system.

An international team of researchers led by UC Davis geneticist Suma Shankar has discovered a new gene implicated in a neurodevelopmental condition called DPH5-related diphthamide-deficiency syndrome. The syndrome is caused by DPH5 gene variants that may lead to embryonic death or profound neurodevelopmental delays.
Findings from their study were published in Genetics in Medicine.
โWe are so excited about the novel gene discovery,โ said the lead author Suma Shankar, professor in the Departments of Pediatrics and Ophthalmology and faculty at the UC Davis MIND Institute. Shankar is the director of Precision Genomics, Albert Rowe Endowed Chair in Genetics, and chief of Division of Genomic Medicine.

A new discovery from Tel Aviv University may provide a key to a great scientific enigma: How does the awake brain transform sensory input into a conscious experience? The groundbreaking study relied on data collected from electrodes implanted, for medical purposes, deep in the human brain. The information was utilized to examine differences between the response of the cerebral cortex to sounds in sleep vs. wakefulness, at a resolution of single neurons.
Amazon is quietly developing cancer vaccines in partnership with Fred Hutchinson and recruiting patients for a new clinical trial

Distinct neuron types in the auditory organ are necessary for encoding different features of sound and relaying them to the brain. Researchers at Karolinska Institutet provide evidence of an early, neuronal activity-independent, emergence of the different subtypes of auditory neurons, prior to birth in mice. The findings have recently been published in Nature Communications.
Neurons specialized in encoding sound emerge before birth
Distinct neuron types in the auditory organ are necessary for encoding different features of sound and relaying them to the brain. Researchers at Karolinska Institutet provide evidence of an early, neuronal activity-independent, emergence of the different subtypes of auditory neurons, prior to birth in mice. The findings have recently been published in Nature Communications.
Previous studies have provided ambiguous results on whether the different subtypes of auditory neurons emerge during prenatal or postnatal development, with in the latter case, a possible role of neuronal activity in generating their diversity. In this new study, researchers demonstrate that the fate of auditory neuron subtypes is under genetic control in the prenatal period, and reveal the complex molecular networks controlling their genesis.
