WASHINGTON (Reuters) – Earth’s magnetic field has been a life preserver, protecting against relentless solar winds, streams of charged particles rushing from the Sun, that otherwise could strip away the planet’s atmosphere and water.
“It would be a pretty barren planet without it,” said University of Rochester geophysicist John Tarduno.
WASHINGTON (Reuters) – They look alike, act alike and long have been considered to be the same species. But, in the case of the golden jackals found across parts of Africa, the Middle East, Asia and Europe, it turns out that appearances can be deceiving.
Scientists said on Thursday a comprehensive genetic analysis found that these populations are made up of two entirely distinct species, with those in Africa different from the others.
WASHINGTON (Reuters) – Democratic U.S. Congressman Chaka Fattah of Pennsylvania and four associates were charged on Wednesday in a political corruption case with bribery and misusing hundreds of thousands of dollars of federal, charitable and campaign funds.
Fattah, 58, who has represented Philadelphia in the U.S. House of Representatives for two decades and is one of the senior black lawmakers in Congress, and the others were indicted by a federal grand jury on 29 counts in an alleged racketeering conspiracy, the U.S. Department of Justice said.
WASHINGTON (Reuters) – If you want to know the secret behind the success of Tyrannosaurus rex and its meat-eating dinosaur cousins, look no further than their teeth.
Scientists on Tuesday unveiled a comprehensive analysis of the teeth of the group of carnivorous dinosaurs called theropods, detailing a unique serrated structure that let them chomp efficiently through the flesh and bones of large prey.
WASHINGTON (Reuters) – If you feel like a human scream jolts the deep recesses of your brain, there’s a good reason for it. That is precisely what is happening, scientists say.
Researchers who explored how the brain handles a scream said on Thursday the loud, high-pitched sound targets a deep brain structure called the amygdala that plays a major role in danger processing and fear learning.
WASHINGTON (Reuters) – Polar bears are the kings of the ice surface covering the top of the globe, but the ongoing loss of the Arctic sea ice on which they hunt seals is causing summer food deprivation that threatens these imposing white-furred predators.
Some experts had thought the bears might be able to mitigate the effects of reduced food intake by entering a “walking hibernation” during summers, an energy-conserving state of reduced activity and metabolic rate akin to the winter hibernation other bear species undertake.
WASHINGTON (Reuters) – Scientists have unearthed a spectacularly preserved, nearly complete fossil in northeastern China of a feathered dinosaur with wings like those of a bird, although they doubt the strange creature could fly.
The researchers on Thursday said the fast-running meat-eater was about 6 feet (1.8 meters) long and covered with simple hair-like feathers over much of its body, with large, quill-like feathers on its wings and long tail.
WASHINGTON (Reuters) – Key Republicans distanced themselves on Sunday from presidential candidate Donald Trump’s denunciation of illegal immigrants from Mexico as rapists and criminals, saying he has become “a wrecking ball” for the party’s ability to win Hispanic voters.
Announcing his candidacy last month, Trump accused Mexico of sending rapists and other criminals into the United States. He later added that illegal border-crossers from Mexico were carrying “tremendous infectious disease”.
WASHINGTON (Reuters) – President Barack Obama on Friday created three new U.S. national monuments in Texas, Nevada and California spanning more than a million acres (400,000 hectares) in a move he said helps preserve America’s beauty but that Republicans condemned as a “surreptitious land grab.”
Acting under a 1906 federal law called the Antiquities Act, Obama established National Monument in California, the Waco Mammoth National Monument in Texas and the Basin and Range National Monument in Nevada.
WASHINGTON (Reuters) – Donald Trump, who became the center of attention in the race for the 2016 Republican U.S. presidential nomination with his denunciation of illegal immigrants from Mexico, has vaulted into a virtual dead heat with Jeb Bush atop the field, a Reuters-Ipsos poll released on Saturday showed.
Trump, a billionaire real estate developer, had the support of 15.8 percent of respondents in the online poll of self-identified Republicans compared to 16.1 percent for Bush, a former Florida governor.
