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.

Brazil Fires Drive Acceleration in Amazon Deforestation

A record fire season in Brazil last year caused the rate of deforestation to accelerate, in a blow to President Luiz Inacio Lula da Silva's pledge to protect the Amazon rainforest, official figures showed Friday.

The figures released by the National Institute for Space Research (INPE), which tracks forest cover by satellite, indicated that deforestation rate between August 2024 and May 2025 rose by 9.1 percent compared to the same period in 2023-2024, said AFP.

And they showed a staggering 92-percent increase in Amazon deforestation in May, compared to the year-ago period.

That development risks erasing the gains made by Brazil in 2024, when deforestation slowed in all of its ecological biomes for the first time in six years.

The report showed that beyond the Amazon, the picture was less alarming in other biomes across Brazil, host of this year's UN climate change conference.

In the Pantanal wetlands, for instance, deforestation between August 2024 and May 2025 fell by 77 percent compared to the same period in 2023-2024.

Presenting the findings, the environment ministry's executive secretary Joao Paulo Capobianco chiefly blamed the record number of fires that swept Brazil and other South American countries last year, whipped up by a severe drought.

Many of the fires were started to clear land for crops or cattle and then raged out of control.
