The new study, which was published online June 7 in the journal Nature Communications also found that the new structure could contribute to infertility, miscarriages and birth defects.

However, the positive thing here is that once the researchers understand this structure better, it may assist them develop new therapies for male infertility and learn more about early human embryonic development.

Massachusetts Institute of Technology (MIT) researchers, working with scientists from Brigham and Women's Hospital, have developed a new way to power and communicate with devices implanted deep inside the human body.

The devices which are powered by a radio frequency waves which can safely pass through human tissues, could be used to deliver drugs, monitor conditions inside the body, or treat disease by stimulating the brain with electricity or light.

While conducting tests on animals, the researchers found that the waves can power devices located 10 centimeters deep in tissue, from distance of 1 meter.

As many as 70 percent of women with the most common form of breast cancer may be able to skip chemotherapy, based on their score on a genetic test, researchers said Sunday.
