Chemical reaction in birds provides sense of direction during migratory flights
...earchers fed high-frequency currents from a signal generator into a coil that surrounded four test cages. The coil, with a diameter of approximately two meters, could be moved to change the alignment of the oscillating field. Each bird was tested once a day during dusk for a period of approximately 75 minutes....Neural biology explains ejaculation
...tion. But the location of this spinal ejaculation generator remained a mystery until last August when Dr. Coolen and a postdoctoral fellow in her laboratory, Dr. William Truitt, reported their findings in Science . Dr. Coolen had targeted the lumbar spinothalamic neurons in the lower back because these neur...Scientists conduct first DNA field tests on Antarctic soil microbes
... Adelaide, Australia. They relied on a small Honda generator to power their operations. The researchers would sit cross-legged on the floor of the tent or on the First Aid box doing delicate genetic tests including DNA extractions, electrophoresis, and PCR analyses as the wind howled around them. It was defini...New research may lead to more effective treatment of asthmatic attacks

... large fish tanks to low-energy radio waves from a generator placed roughly a meter away. All died within 40 days. In the unexposed group, only 10 percent of the mussels died. Moreover, the researchers measured a fourfold increase of calcium in the water compared to the unexposed group. Ryan says, If you have ...Lab on a chip?
