Last spring, the strongest geomagnetic storm in two decades slammed Earth, producing light displays across the Northern Hemisphere. And last fall, a powerful solar storm dazzled skygazers far from the Arctic Circle when dancing lights appeared in unexpected places including Germany, the United Kingdom, New England and New York City.Aurora displays known as the northern and southern lights are commonly visible near the poles, where charged particles from the sun interact with Earth’s atmosphere.

Skygazers are spotting the lights deeper into the United States and Europe because the sun is going through a major facelift. Every 11 years, its poles swap places, causing magnetic twists and tangles along the way.Severe storms are capable of scrambling radio and GPS communications.The sun’s active spurt is expected to last at least through the end of this year, though when solar activity will peak won’t be known until months after the fact, according to NASA and NOAA.

Solar storms can bring more than colorful lights to Earth.When fast-moving particles and plasma slam into Earth’s magnetic field, they can temporarily disrupt the power grid. Space weather can also interfere with air traffic control radio and satellites in orbit.

In 1859, a severe solar storm triggered auroras as far south as Hawaii and caught telegraph lines on fire in a rare event. And a 1972 solar storm may have detonated magnetic U.S. sea mines off the coast of Vietnam.

Space weather experts aren’t able to predict a solar storm months in advance. Instead, they alert relevant parties to prepare in the days before a solar outburst hits Earth.Other components have been added to formula in recent years. They include docosahexaenoic acid, or DHA, an essential omega-3 fatty acid, and human milk oligosaccharides, complex sugars that are found breast milk but not in cow’s milk. Although they may be beneficial, they are not required.

“These have been added to some formulas, but not to other formulas, so we want to take a look,” Abrams explained.Many parents have raised concerns over formula ingredients such as added sugars and

, which are also being targeted by Kennedy as hazards in the wider food supply.Recent research suggests that added sugars such as glucose and corn syrup solids in infant formula may be linked to weight gain in children. Young said that most experts agree that lactose, the primary type of sugar found in breast milk, is preferred.
