An Egyptian scientist says some 20 swarms have invaded the country in the past three months and more are waiting in the wings.

Researchers simulate changes in sea ice and determine that regular ocean passages will be possible by mid-century.
The study estimates that 100 million sharks are killed globally every year. Shark populations are especially vulnerable because they do not reproduce quickly or early on in life. New protections are up for consideration at an international conference Sunday.
SpaceX founder Elon Musk says the resupply mission to the space station experienced a thruster problem, but it has been fixed.
The medal, along with other items that belonged to the late Francis Crick, will be auctioned on April 10-11 in New York.
The Chelyabinsk meteor was part of a group of Earth-crossing objects known as Apollo asteroids, scientists believe.
From Japan comes news of a giant isopod that knows all there is to know about the hunger game. How else to explain the fasting behavior of the animal that, his minders say, hasn't eaten in more than 1,500 days? The male giant isopod, known simply as No. 1, last ate on Jan. 2, 2009 — or, to put it in perspective, 18 days before President Obama began his first term.
Scientists believe a long-lost land mass, sandwiched between the land masses that make up today's India and Madagascar, was lost on the sea tens of millions of years ago.
The meteor that caused at least 1,000 injuries in Russia after a startling and powerful daytime explosion one week ago has been identified as a chondrite, the most common type of meteor that falls on Earth. But that hasn't stopped a black-market economy from developing around the fragments.
Japan says an auxiliary battery was improperly connected to the main battery that overheated, forcing an emergency landing.
Hurricanes often weaken as they travel north across colder water and approach land. But Sandy hasn't. One reason is that it's expected to change from a tropical storm powered by warm ocean water to something more like a winter storm powered by temperature and pressure differences in the atmosphere.
It's still unclear whether Sandy, which was both downgraded then upgraded early Saturday morning, will be a devastating storm or just a bad one. It is clear, however, that Sandy will be remembered as the storm that broke all the rules and baffled the nation's top weather forecasters.
Because about half of all drugs act on the receptors that let humans sense their environment, the scientists' work has been incredibly important for the development of pharmaceuticals.
Serge Haroche of France and David Wineland of the United States have been honored for their work on the interaction between life and matter — in particular, the "fundamental interactions between light particles and matter."
John B. Gurdon and Shinya Yamanaka discovered that mature and specialized cells "can be reprogrammed to become immature cells capable of developing into all tissues of the body," according to the Nobel committee.
NASA's Curiosity rover has found definitive proof that water once ran across the surface of Mars, the agency announced today. NASA scientists say that new photos from the rover show rocks that were smoothed and rounded by water. The rocks are in a large canyon and nearby channels that were cut by flowing water, making up an alluvial fan.
Riding piggy-back atop a Boeing 747, the shuttle performed a fly-by at several iconic spots, from Malibu and Santa Monica to the Getty Center, the Griffith Observatory, and Vandenberg Air Force Base.
A scientist discovered the first lesula specimen being kept as a pet in the Democratic Republic of Congo in 2007.
A French study of clay formation in the South Pacific islands casts doubt on how scientists have long believed similar clays were deposited on Mars.
