“Vaping and dabbing were most common among young adults aged 18–24 years. Trends in both of these routes of use have increased among adolescents and young adults.”
How does the average U.S. adult consume marijuana? This is what a recent report published by the Centers for Disease Control and Prevention (CDC) hopes to address as a team of CDC researchers investigated the range of cannabis products that are used by U.S. adults and which products are used more than others. This report has the potential to help scientists, legislators, and the public better understand cannabis use throughout the United States and develop educational and preventive measures for its use.
The report states, “As the availability and types of cannabis products expand, less is known about how persons consume cannabis. Historically, cannabis has most often been smoked; however, additional routes of use are available, including oral ingestion, vaping, and more recently, dabbing (i.e., inhalation of highly concentrated THC-based oils often heated using a blowtorch).”
For the study, the researchers conducted a survey of 138,625 participants to identify how both the frequency and method of cannabis use and broken up into several age groups. In the end, they found that 14,044 (15.3%) used cannabis with 6,848 (7.9%) using it daily. They found that 79.4% smoked cannabis while eating, vaping, and dabbing comprised 41.6%, 30.3%, and 14.6%, respectively. Additionally, 29.3% of non-Hispanic American Indian or Alaska Native (AI/AN) individuals were found to participate in dabbing, along with 23% of individuals without a high school diploma.
Complex neural circuits likely arose independently in birds and mammals, suggesting that vertebrates evolved intelligence multiple times.
Concentrating light in a volume as small as the wavelength itself is a challenge that is crucial for numerous applications. Researchers from AMOLF, TU Delft, and Cornell University in the U.S. have demonstrated a new way to focus light on an extremely small scale. Their method utilizes special properties of a photonic crystal and works for a broader spectrum of wavelengths than alternative methods. The researchers published their findings in Science Advances on April 18.
I’m writing this from a laptop that’s stalling and refusing to switch between tabs because it’s gotten too warm in the early Indian summer. It’s not like I’m running a hectic workload of video and audio editing tools and multiple browsers at once: this old machine just can’t move heat away from the processor and other internals quickly enough.
That results in throttling, or reducing the clock speed at high temperatures, in order to prevent overheating and damage to the internal components. But a new finding from the University of Virginia School of Engineering and Applied Science could make that a thing of the past – with crystals.
When electronic components like the processor in your laptop are working at full tilt, they can get pretty hot. The same can be said for chips in a range of other devices, and even batteries in electric cars. Now, if these components are squashed into tight spaces, you’re going to see heat build up there and take a long time to dissipate.
