Millions of Americans have peripheral artery disease, a disorder primarily caused by fatty deposits that can narrow arteries and block blood flow to the legs. Often, the first symptom they feel is leg pain. Experts say that most treatments are safe, but some have expressed a growing sense of alarm that doctors may be doing procedures that patients don’t need, exposing them to unnecessary risks.

ProPublica looked into artery procedures and found that some doctors are making millions of dollars doing a questionable number of treatments. Government insurers pay well for vascular procedures that are done outside of hospitals, and doctors can bill tens of thousands of dollars for treatments done in a single office visit.

One doctor in Maryland made millions of dollars from the federal government for performing thousands of vascular procedures. A state medical board investigation found that his inappropriate treatments put patients at risk of serious harm. One man had to have his leg amputated after invasive treatments for mild pain, according to filings in a settled lawsuit. A grandmother bled out and died shortly after the same doctor cut into her, according to another ongoing lawsuit. The doctor denied the allegations in legal filings, but declined to be interviewed and did not respond to emailed questions.

July 3 (Reuters) - Elon Musk’s Twitter has put a temporary limit on the number of tweets that users can see each day, a move that has sparked some backlash and could undermine the social network’s efforts to attract advertisers.

The limit, imposed to “address extreme levels of data scraping and system manipulation”, is the latest change by Twitter, which was last year acquired by Musk for $44 billion.

What does the latest change mean and what are the alternatives to Twitter? How do the changes impact users?

Users cannot view tweets without logging in to the platform. Verified accounts can now read 6,000 posts per day, unverified accounts 600 posts and new un-verified accounts 300 posts. After that, users will get a message that says, “rate limit exceeded”.

A 25-year science wager has come to an end. In 1998, neuroscientist Christof Koch bet philosopher David Chalmers that the mechanism by which the brain’s neurons produce consciousness would be discovered by 2023. Both scientists agreed publicly on 23 June, at the annual meeting of the Association for the Scientific Study of Consciousness (ASSC) in New York City, that it is still an ongoing quest — and declared Chalmers the winner.

What ultimately helped to settle the bet was a key study testing two leading hypotheses about the neural basis of consciousness, whose findings were unveiled at the conference.

“It was always a relatively good bet for me and a bold bet for Christof,” says Chalmers, who is now co-director of the Center for Mind, Brain and Consciousness at New York University. But he also says this isn’t the end of the story, and that an answer will come eventually: “There’s been a lot of progress in the field.”

June 26 (Reuters) - U.S. President Joe Biden on Monday plans to lay out how a $42 billion investment in expanding internet access will be divvied up among the nation's 50 states, in an effort to give all Americans access to high-speed broadband by 2030.

The move will kick off the second leg of Biden's tour highlighting how legislation passed by Congress during the first half of his term will affect average Americans, as his reelection bid gears up.

"We have an historic opportunity here to make a real difference in people's lives and making sure that we deliver on that potential is what we're about every day and to make sure that people feel that at their kitchen table, in their communities, in their backyards,” White House chief of staff Jeff Zients said.

Zients compared the broadband effort to President Franklin Roosevelt's efforts in 1936 to bring electricity to rural America. The administration estimates there are some 8.5 million locations in the U.S. that lack access to broadband connections.

You're familiar with the states of matter we encounter daily – such as solid, liquid, and gas – but in more exotic and extreme conditions, new states can appear, and scientists from the US and China just found one.

They're calling it the chiral bose-liquid state, and as with every new arrangement of particles we discover, it can tell us more about the fabric and the mechanisms of the Universe around us – and in particular, at the super-small quantum scale.

Behold the most nauseating and mesmerizing swim advisories floating around.

The Yellowstone County Sheriff's Office wrote on Facebook on Saturday morning that multiple tanker cars were "damaged and leaking petroleum products near the Yellowstone River."

Later reports from other agencies in addition to photos from the derailment indicate that the train had crashed into the Yellowstone River when a bridge collapsed early Saturday morning.

It’s well known that global sea levels are rising, but now NASA is showing by just how much.

The National Aeronautics and Space Administration shared an animation that shows how far sea levels have risen between 1993 and 2022.

Over those three decades, sea levels have risen about 3.5 inches.

That may not seem like a lot, but the animation should be used as a visual metaphor. NASA said it’s designed to look like a submerged porthole of a boat as water can be seen lapping outside the window.
