The Standard Days Method (TM), a new natural method of family planning, is more than 95% effective at preventing pregnancy, according to an international study conducted by Georgetown University Medical Center’s Institute for Reproductive Health. Results of the study are published in the current issue of Contraception, the journal of the Association of Reproductive Health Professionals.
Based on sophisticated computer modeling of reproductive physiology data, the Standard Days Method identifies the 12-day "fertile window" of a woman’s menstrual cycle. These 12 days take into account the life span of the woman’s egg (about 24 hours) and the viable life of sperm (about 5 days) as well as the variation in the actual timing of ovulation from one cycle to the next. The study found the efficacy of the Standard Days Method to be comparable to or better than a number of other widely used methods of family planning, including the diaphragm and condom.
The two-year clinical trial evaluated the effectiveness of the Standard Days Method of family planning for 478 women in Bolivia, Peru and the Philippines. The women were of childbearing age with menstrual cycles between 26 and 32 days long. The study followed the women over 13 cycles.

Nanooptical traps are a promising building block for quantum technologies. Austrian and German scientists have now removed an important obstacle to their practical use. They were able to show that a special form of mechanical vibration heats trapped particles in a very short time and knocks them out of the trap.
By controlling individual atoms, quantum properties can be investigated and made usable for technological applications. For about ten years, physicists have...
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...
