A new alternative to opioids
2025-08-04
Kyoto, Japan -- Opioids like morphine are widely used in medical practice due to their powerful pain-relieving effects. However, they carry the risk of serious adverse effects such as respiratory depression and drug dependence. For this reason, Japan has strict regulations in place to ensure that these medications are prescribed only by authorized physicians.
In the United States, however, the opioid OxyContin was once prescribed frequently triggering a surge in the misuse of synthetic opioids such as fentanyl. As a result, the number of deaths caused by opioid overdose surpassed 80,000 in 2023, escalating ...
Tracing brain chemistry across humanity’s family tree
2025-08-04
The evolutionary success of our species may have hinged on minute changes to our brain biochemistry after we diverged from the lineage leading to Neanderthals and Denisovans about half a million years ago
Two of these tiny changes that set modern humans apart from Neanderthals and Denisovans affect the stability and genetic expression of the enzyme adenylosuccinate lyase, or ADSL. This enzyme is involved in the biosynthesis of purine, one of the fundamental building blocks of DNA, RNA, and other important biomolecules. In a study now published in PNAS, researchers from the Okinawa Institute of Science and Technology (OIST), Japan and the Max Plank Institute for Evolutionary ...

Gigantic, meat-eating dinosaurs didn’t all have strong bites
2025-08-04
A new analysis of the bite strength of 18 species of carnivorous dinosaurs shows that while the Tyrannasaurus rex skull was optimized for quick, strong bites like a crocodile, other giant, predatory dinosaurs that walked on two legs—including spinosaurs and allosaurs—had much weaker bites and instead specialized in slashing and ripping flesh. Reported in the Cell Press journal Current Biology on August 4, these findings demonstrate that meat-eating dinosaurs followed different evolutionary paths in terms of skull design and feeding style despite their similarly gigantic sizes.
“Carnivorous dinosaurs took very different paths as they ...
