Physics news

	Researchers achieve breakthrough in silicon-compatible magnetic whirls Researchers from Oxford University's Department of Physics have made a breakthrough in creating and designing magnetic whirls in membranes that can be seamlessly integrated with silicon. These hurricane-like magnetic whirls, thought to move at incredible speeds of up to kilometers per second could be used as information carriers in a new generation of green and super-fast computing platforms.

Electrons move, current flows, and signals are transmitted by applying an electrical voltage. However, there is also another way to manipulate electronic currents and signals: using the properties of the spin—the intrinsic magnetic moment of the electron. This is called "spintronics," and it has become an increasingly important field in contemporary electronic research.

	Oocytes outsmart toxic proteins to preserve long-term female fertility Oocytes are immature egg cells that develop in almost all female mammals before birth. The propagation of future generations depends on this finite reserve of cells surviving for many years without incurring damage. In mice, this can be a period of up to 18 months, while in humans it can last almost half a century, the average time between birth and menopause. How the cells accomplish this remarkable feat of longevity has been a longstanding question.
