The first experimental vaccine to be tested in the United States for treatment of opioid use disorder is being studied in a phase 1a/1b clinical trial led by researchers at Columbia University Vagelos College of Physicians and Surgeons. “We have good medications to treat opioid use disorder, but about half of the people who use […]

Marijuana use continued to rise among college students over the past five years and remained at historically high levels among same-aged peers who are not in college in 2020, according to survey results from the 2020 Monitoring the Future (MTF) panel study. This represents the highest levels of marijuana use recorded since the 1980s. The survey also found that marijuana vaping and nicotine vaping leveled off in 2020 after sharp increases reported every year since 2017 […]

When stretched or deformed, shape memory polymers return to their original shapes after heat or light is applied. These materials show great promise for soft robotics, smart biomedical devices and deployable space structures, but until now they haven’t been able to store enough energy. Now, researchers reporting in ACS Central Science have developed a shape memory polymer […]

Palaeontologists at the Royal Ontario Museum (ROM) have uncovered the remains of a huge new fossil species belonging to an extinct animal group in half-a-billion-year-old Cambrian rocks from Kootenay National Park in the Canadian Rockies. The findings were announced on September 8, 2021, in a study published in Royal Society Open Science. Named Titanokorys gainesi, this new species […]

Smaller is better when it comes to the flexible plastic endotracheal tubes placed in the windpipe to help patients breathe, say the medical professionals who treat vocal professionals. Endotracheal tubes, which come in a wide range of sizes, are placed in a process called intubation in ICU and trauma patients as well as in individuals […]

Researchers at the University of Helsinki and LUT University, Finland, have analyzed the extent to which insect protein could help to reduce global warming associated with food consumption in Europe. They have especially focused on insect protein use and soybean-protein use in the production of broilers. The results support previous research suggesting that insect protein […]

Researchers have discovered a way to use mining waste as part of a potential cheaper catalyst for hydrogen fuel production. Water splitting reactions that produce hydrogen are triggered using rare platinum ($1450/ounce), iridium ($1370/ounce) and ruthenium ($367/ounce), or cheaper but less active metals—cobalt ($70,000/tonne), nickel ($26,000/tonne) and iron ($641/tonne). Professor Ziqi Sun from the QUT […]

Police forces in England say the potential for significant harm to people who go missing is rising after decades of cuts to police budgets, rising demand and lack of training. In the first report to examine whether swinging cuts to police budgets introduced since 2010 have had any impact on missing people investigations, the authors […]

An artificial intelligence (AI) program can spot signs of lung cancer on CT scans a year before they can be diagnosed with existing methods, according to research presented at the European Respiratory Society International Congress. [1] Lung cancer is the most common cause of cancer death with around 1.8 million lives lost around the world each […]

An analysis by Chinese researchers suggests that over 40% of items on the US export control list are scientific instruments required by China’s laboratory researchers. Of 12 categories defined by the US government, analytical instruments such as mass spectrometers, process laboratory equipment including tools used in the chemical and pharmaceutical sectors, and performance testing instruments […]
