| Changed gene expression after heart surgery extends cardiomyocyte regeneration Posted: 24 Jun 2022 01:07 PM PDT While lower vertebrates can repair their adult hearts after a heart attack, mammals -- including humans -- cannot. The ability to regenerate dead muscle tissue in mammalian hearts disappears just a few days after birth because the heart muscle cells, called cardiomyocytes, exit the cell cycle. In 2020, researchers reported that surgery to remove the left ventricle apex of the heart of pigs, one day after birth, somehow extended the replication ability of heart muscle cells. To better understand the underlying gene expression changes in this extended regeneration window, researchers now report nuclear RNA-sequencing of heart muscle cells, using this porcine model. From such knowledge, and much further research yet to come, clinicians may potentially learn how to regenerate adult heart cardiomyocytes after a heart attack. |
| 3D printing of 'organic electronics' Posted: 24 Jun 2022 01:06 PM PDT A research group has explored the potential production of micro-scale organic electronics for use in bioelectronics via multiphoton 3-D printers. |
| The octopus' brain and the human brain share the same 'jumping genes' Posted: 24 Jun 2022 07:51 AM PDT The neural and cognitive complexity of the octopus could originate from a molecular analogy with the human brain, according to a new study. The research shows that the same 'jumping genes' are active both in the human brain and in the brain of two species, Octopus vulgaris, the common octopus, and Octopus bimaculoides, the Californian octopus. |
| Climate change negatively impacting bumble bees Posted: 24 Jun 2022 06:24 AM PDT Temperature changes have negatively impacted most species of bumble bees over the past 120 years, according to new new research. The researchers note that changes in temperature had more of a negative impact than other factors -- such as precipitation or floral resources. |
