Scientists have developed a new painkiller, which has the same morphine effect when given at a hundred times lower dose. The new drug is still under trial. According to a study published Saturday in the US Science Translational Medicine journal, the AT121 compound does not cause the same side effects caused by other harsh painkillers.

Mei-Chuan Ko, professor at the Wake Forest Baptist Medical Center, said: “In our study, we found AT-121 to be safe and non-addictive, as well as an effective pain medication. In addition, this compound also was effective at blocking abuse potential of prescription opioids, much like buprenorphine does for heroin, so we hope it could be used to treat pain and opioid abuse."

According to the US Department of Health and Human Services, more than 115 people die from opium overdoses each year in the United States.

Over 21-29 percent of patients with medical prescriptions including opium compounds used to relieve chronic pain have suffered from subsequent addiction. As of July 2017, opium addiction cases increased by 30 percent in 42 US states.

The currently marketed opium drugs focus on the so-called opioid receptors, a part of the brain that works to help people not to feel pain. Researchers have been working on developing a drug that can stimulate this part of the brain to avoid the side effects of opium, mainly addiction, shortness of breath, and increased sensitivity to pain later.

Olympic Balloon to Rise again in Paris

A giant balloon that became a popular landmark over the skies of Paris during the 2024 Olympics is set to rise again, with organizers hoping it will once again attract crowds of tourists.

During the Games, the Olympic cauldron tethered to a balloon flew above the Tuileries garden at sunset every day, with thousands flocking to see the seven-meter (23 feet) wide ring of electric fire, AFP said.

Last summer's version "had been thought up to last for the length of the Olympic and Paralympic Games," said Mathieu Lehanneur, the designer of the cauldron.

After President Emmanuel Macron "decided to bring it back, all of the technical aspects needed to be reviewed", he told AFP on Thursday.

Lehanneur said he was "very moved" that the Olympic balloon was making a comeback.

"The worst thing would have been for this memory to become a sitting relic that couldn't fly anymore," he said.

The new cauldron will take to the skies on Saturday evening during France's annual street music festival, the Fete de la Musique.

The balloon will rise into the air every evening until September 14 -- a summer tradition set to return every year until the 2028 Los Angeles Games.

"For its revival, we needed to make sure it changed as little as possible and that everything that did change was not visible," said Lehanneur.

With a decarbonated fire patented by French energy giant EDF, the upgraded balloon follows "the same technical principles" as its previous version, said director of innovation at EDF Julien Villeret.

The improved attraction "will last ten times longer" and be able to function for "300 days instead of 30", according to Villeret.

The creators of the balloon also reinforced the light-and-mist system that "makes the flames dance", he said.

Under the cauldron, a machine room hides cables, a compressor and a hydro-electric winch.

That system will "hold back the helium balloon when it rises and pull it down during descent", said Jerome Giacomoni, president of the Aerophile group that constructed the balloon.

"Filled with 6,200 m3 of helium that is lighter than air," the Olympic balloon "will be able to lift around three tons" of cauldron, cables and attached parts, he said.

The Tuileries garden is where French inventor Jacques Charles took flight in his first gas balloon on December 1, 1783, Giacomoni added.

He followed in the footsteps of the famed Montgolfier brothers, who had just nine days earlier elsewhere in Paris managed to launch a similar balloon into the sky with humans onboard.
