Cannabis use frequency and cannabis-related consequences in high-risk young adults across cannabis legalization

JAMA Network Open

2023-09-27
(Press-News.org)

About The Study: In a study of 619 high-risk young adults in Ontario, Canada, individuals using cannabis frequently pre-legalization showed significant reductions in use and consequences over time, reflecting an aging out pattern. Small increases in use among participants with no pre-legalization use were observed over time, but without parallel changes in cannabis-related consequences. The results did not reveal substantive adverse near-term outcomes across the legalization period, although a within-participants design cannot rule out the possibility of alternative trajectories in the absence of legalization. 

Authors: Amanda Doggett, Ph.D., of McMaster University/St. Joseph’s Healthcare in Hamilton, Ontario, Canada, is the corresponding author.

Decriminalizing drug possession not linked to higher overdose death rates in Oregon or Washington

2023-09-27
In recent months, several media outlets have investigated an Oregon law that decriminalized possession of small amounts of controlled substances, including heroin, cocaine and methamphetamine, for some persons.  The articles have included information suggesting that the law may be responsible for continued increases in overdose deaths. Today, new research led by NYU Grossman School of Medicine published online in JAMA Psychiatry suggests that in Oregon and Washington, two states that implemented drug decriminalization policies ...

Impact of genes linked to neurodevelopmental diseases found in Stanford Medicine-led study

2023-09-27
Stanford Medicine investigators and their colleagues sifted through a jumble of genes implicated in neurodevelopmental disorders and identified dozens of disparate troublemakers with similar effects. Because the method they used sorts defective genes by their function — or in this case, their dysfunction — the approach is likely to accelerate drug development for neurodevelopmental disorders. Studies have implicated at least 500 genes in such disorders. But scientists have no idea exactly how defects in most of these genes impair brain function. The ...

Powering the quantum revolution: Quantum engines on the horizon

Powering the quantum revolution: Quantum engines on the horizon
2023-09-27
Quantum mechanics is a branch of physics that explores the properties and interactions of iparticles at very small scale, such as atoms and molecules. This has led to the development of new technologies that are more powerful and efficient compared to their conventional counterparts, causing breakthroughs in areas such as computing, communication, and energy.   At the Okinawa Institute of Science and Technology (OIST), researchers at the Quantum Systems Unit have collaborated with scientists from the University ...

New proof for black hole spin

New proof for black hole spin
2023-09-27
The supermassive black hole at the heart of galaxy M87, made famous by the first picture of a black hole shadow, has yielded another first: the jet shooting out from the black hole has been confirmed to wobble, providing direct proof that the black hole is spinning. Super massive black holes, monsters up to billions of times heavier than the Sun that eat everything around them including light, are difficult to study because no information can escape from within. Theoretically, there are very few properties that we can even hope to measure. One property that might possibly be observed is spin, but due to the difficulties involved there have been no direct ...

Monitoring of radio galaxy M87 confirms black hole spin

Monitoring of radio galaxy M87 confirms black hole spin
2023-09-27
The nearby radio galaxy M87, located 55 million light-years from the Earth and harboring a black hole 6.5 billion times more massive than the Sun, exhibits an oscillating jet that swings up and down with an amplitude of about 10 degrees, confirming the black hole's spin. The study, which was headed by Chinese researcher Dr. CUI Yuzhu and published in Nature on Sept. 27, was conducted by an international team using a global network of radio telescopes. Through extensive analysis of telescope data from 2000­–2022, the research team revealed a recurring 11-year cycle in the precessional motion of the jet base, as predicted ...

Desalination system could produce freshwater that is cheaper than tap water

Desalination system could produce freshwater that is cheaper than tap water
2023-09-27
Engineers at MIT and in China are aiming to turn seawater into drinking water with a completely passive device that is inspired by the ocean, and powered by the sun.  In a paper appearing today in the journal Joule, the team outlines the design for a new solar desalination system that takes in saltwater and heats it with natural sunlight.  The configuration of the device allows water to circulate in swirling eddies, in a manner similar to the much larger “thermohaline” circulation of the ocean. This circulation, ...

Protecting lands slows biodiversity loss among vertebrates by five times

Protecting lands slows biodiversity loss among vertebrates by five times
2023-09-27
Protecting large swaths of Earth’s land can help stem the tide of biodiversity loss—including for vertebrates like amphibians, reptiles, mammals and birds, according to a new study published in Nature Sept. 27. The study, led by the Smithsonian Environmental Research Center (SERC) and Conservation International, emphasizes the importance of proper governance for the success of protected lands, and offers much-needed support for the United Nations’ “30 by 30” initiative to conserve the ...

How an audience changes a songbird’s brain

How an audience changes a songbird’s brain
2023-09-27
NEW YORK, NY — His mind might have been set on finding water or on perfecting a song he learned as a chick from his dad. But all of that gets pushed down the to-do list for an adult male zebra finch when he notices a female has drawn nigh.    “The males stop worrying about anything else and, for the first time, we have found signs of that re-prioritization in the behavior of specific brain cells,” said Vikram Gadagkar, PhD, a principal investigator at Columbia’s Zuckerman Institute and a co-first author, along with graduate student Andrea Roeser of Cornell ...

Organic lasers have a bright future

2023-09-27
Scientists at St Andrews are leading a significant breakthrough in a decades-long challenge to develop compact laser technology. Lasers are used across the world for a huge range of applications in communications, medicine, surveying, manufacturing and measurement.  They are used to transmit information across the internet, for medical treatments, and even in the face scanner on phones.  Most of these lasers are made from rigid, brittle, semiconductor crystals such as gallium arsenide. Organic semiconductors are a newer class of electronic material. Flexible, based on carbon and emitting visible ...

Women’s mood worsens during ‘pill pause’ period of monthly contraceptive pill cycle

2023-09-27
Type of work: peer-reviewed/observational study/people Barcelona: Most contraceptive pills are based on a cycle of taking the pill for 21 days, and then stopping the pill for 7 days. Now researchers have found that women’s mood worsens during the 7 pill-free days. This work will be presented at the ECNP congress in Barcelona on 8th October, after recent publication (see notes). Lead researcher, Professor Belinda Angela Pletzer (of Paris Lodron University, Salzburg, Austria) said “We investigated women’s mental health during the pill pause in long-term pill users: since they are long-term ...
