News organizations and journalists' advocates are challenging restrictive new ground rules for reporters assigned to cover the Senate impeachment trial.

Correspondents who submit to an official credentialing process are granted broad access throughout the Capitol complex and usually encounter few restrictions in talking with members of Congress or others.

But now Senate Sergeant-at-Arms Michael Stenger has imposed new requirements for the impeachment trial, negotiated in part with Republican leadership:

On an unusually warm January afternoon, 28-year-old Icy Coomber attended a poster-making session for the fourth annual Women's March in Washington, D.C.

Unlike the friend she accompanied to the event, Coomber did not participate in any of the previous anti-Trump demonstrations. Three years ago, the first march drew hundreds of thousands of people to the nation's capital and hosted sister marches in cities around the world.

The National Academy of Recording Arts and Sciences has placed its president and CEO, Deborah Dugan, on administrative leave in a major shakeup at the organization less than two weeks before this year's Grammy Awards ceremony.

Tesla CEO Elon Musk has always had ambitious goals. Make electric cars cool, save the world, all while making money as a brand new car manufacturer.

And from the start some people have been confident that he would fail. So they shorted Tesla stock — placing a bet that the company's stock value would collapse.

So far, that has been a phenomenally bad bet.

In the first two weeks of 2020 alone, short sellers were down some $2.6 billion, according to Ihor Dusaniwsky, the head of predictive analytics at S3 Partners.

The New York Mets have announced that they are parting ways with their brand-new manager, Carlos Beltrán, amid a sign-stealing scandal that has rocked Major League Baseball.

"This was not an easy decision," Mets COO Jeff Wilpon and general manager Brodie Van Wagenen said in a statement. "Considering the circumstances, it became clear to all parties that it was not in anyone's best interest for Carlos to move forward as Manager of the New York Mets."

A pair of Boeing 737 Max 8 jetliners plummeted from the sky in 2018 and 2019, killing hundreds of passengers and eventually prompting officials to ground the aircraft model worldwide — but the process that allowed the craft in the

It was a lifesaving mission as dramatic as any in the months-long battle against the wildfires that have torn through the Australian bush.

But instead of a race to save humans or animals, a specialized team of Australian firefighters was bent on saving invaluable plant life: hidden groves of the Wollemi pine, a prehistoric tree species that has outlived the dinosaurs.

For decades, scientists have been trying to create machines that mimic the way birds fly. A team from Stanford University has gotten one big step closer.

Microsoft has announced an ambitious plan to not just reduce its carbon emissions, but to actively remove carbon from the atmosphere — going "carbon negative" by 2030.

TSA announced that its officers seized 4,432 guns at checkpoints last year — the most in the agency's 18-year history. It also says that 87% of those guns (some 3,855) were loaded.

Cybercrime is booming, and victims are often at a loss about where to get help.

In theory, Americans should report the crimes to the FBI, via its Internet Crime Complaint Center. In practice, the feds get hundreds of thousands of complaints a year, and have to focus on the biggest cases.

But the other option, calling the police, can seem even less promising.

Since 2017, the Trump administration has placed layers of tough sanctions on Iran in an effort to deprive the regime of financial resources and to force it to negotiate a new nuclear deal.

A medical condition that often escapes public notice may be involved in 20% of deaths worldwide, according to a new study.

The disease is sepsis — sometimes called blood poisoning. It arises when the body overreacts to an infection. Blood vessels throughout the body become leaky, triggering multiple-organ failure.
