Scientists develop way to perform supercomputer simulations of the heart on cellphones

You can now perform supercomputer simulations of the heart's electrophysiology in real time on desktop computers and even cellphones. A team of scientists developed a new approach that can not only help diagnose heart conditions and test new treatments, but pushes the boundaries of cardiac science by opening up a floodgate of new cardiac research and education.

Can a protein in cord blood predict risk of death, cerebral palsy in preterm infants?

Researchers have found that some preterm babies born without haptoglobin, a protein in blood cells, have higher odds of brain bleeding, cerebral palsy and death. Their findings suggest that the absence of the protein could serve as a potential biomarker indicating a need for increased monitoring or other preventive interventions.

Researchers find ancient Maya farms in Mexican wetlands

Archaeologists used the latest technology to find evidence suggesting ancient Maya people grew surplus crops to support an active trade with neighbors up and down the Yucatan Peninsula. The extensive croplands suggest the ancient Maya could grow surplus crops, especially the cotton responsible for the renowned textiles that were traded throughout Mesoamerica.

People can survive organ failure, a review explores how

Although organ failure can be fatal, your kidneys, heart, and liver are prepared for this catastrophe. Emerging research supports the finding that two cell populations quickly respond and work together to restore a non-functioning, or failing, organ. First, the surviving cells go into overdrive, working to keep the organ functioning while stem-like cells replace damaged tissue. A Review explores how this dual-response can save lives.

Researchers have designed two types of nano-sized building blocks that can automatically connect into cubes and scramble back into individual components based on the temperature of their environment. This accomplishment is another step towards chemical systems that more realistically mimic life. 'Imagine mixing two liquids together, like ink and water. They will automatically do the simple chemical process of dispersing until they are perfectly mixed,' said Professor Shuichi Hiraoka of the University of Tokyo.

Introducing a kinder, gentler way to blow holes in cells

Getting big molecules into cells isn't easy, and it isn't easy on the cells, either. Bulk electroporation blows holes throughout the cell and can kill many of them. Viruses like AAV have limited capacity for macromolecules like Cas9, and lentivirus has safety issues. A new, gentler form of electroporation, called nanoEP, causes less trauma to cells and is more efficient, potentially boosting delivery of large molecules for gene editing or CAR T-cell immunotherapy.

'Free lunch' warps inner spatial map in rat brains and, by implication, human brains

Our brains' neural circuitry creates spatial maps as we navigate through new environments, allowing us to recall locations and directions. While it's been known for some time that we have these internal maps, a study shows how, in rats, those maps get redrawn when the rats learn they'll receive a reward at a certain place on the map.
