Scientists at the Duke Comprehensive Cancer Center have scientifically validated for the first time that stem cells in umbilical cord blood can infiltrate damaged heart tissue and transform themselves into the kind of heart cells needed to halt further damage.
Clinical proof of this principle has existed for a decade, as Duke physicians have used cord blood to correct heart, brain and liver defects in children with rare metabolic diseases. But until now they lacked the molecular evidence to prove that cord blood stem cells were the root of a cure.
Now, the Duke team has dissected heart tissue to confirm the presence of donor stem cells in heart tissue. Moreover, they showed that donor stem cells had differentiated into heart muscle cells called myocytes, which then produced the critical enzyme needed to halt the progressive heart damage, said Kirsten Crapnell, Ph.D., a research fellow at Duke.

An international team of scientists, including three researchers from New Jersey Institute of Technology (NJIT), has shed new light on one of the central mysteries of solar physics: how energy from the Sun is transferred to the star's upper atmosphere, heating it to 1 million degrees Fahrenheit and higher in some regions, temperatures that are vastly hotter than the Sun's surface.
With new images from NJIT's Big Bear Solar Observatory (BBSO), the researchers have revealed in groundbreaking, granular detail what appears to be a likely...

Carbon nanotubes (CNTs) are valuable for a wide variety of applications. Made of graphene sheets rolled into tubes 10,000 times smaller than a human hair, CNTs have an exceptional strength-to-mass ratio and excellent thermal and electrical properties. These features make them ideal for a range of applications, including supercapacitors, interconnects, adhesives, particle trapping and structural color.
New research reveals even more potential for CNTs: as a coating, they can both repel and hold water in place, a useful property for applications like printing,...
If you've ever tried to put several really strong, small cube magnets right next to each other on a magnetic board, you'll know that you just can't do it. What happens is that the magnets always arrange themselves in a column sticking out vertically from the magnetic board. Moreover, it's almost impossible to join several rows of these magnets together to form a flat surface. That's because magnets are dipolar. Equal poles repel each other, with the north pole of one magnet always attaching itself to the south pole of another and vice versa. This explains why they form a column with all the magnets aligned the same way.
Now, scientists at ETH Zurich have managed to create magnetic building blocks in the shape of cubes that - for the first time ever - can be joined together to...
