A study published in the scientific journal Addiction provides the most comprehensive evidence to date of the association between recreational cannabis laws (RCLs) in US states and responses in the illegal markets for cannabis, heroin, and other drugs in those states.

An interdisciplinary European collaboration called the Seas Oceans and Public Health In Europe (SOPHIE) Project, led by the University of Exeter and funded by Horizons 2020, has outlined the initial steps that a wide range of organisations could take to work together to protect the largest connected ecoInsystem on Earth. They call for the current UN Ocean Decade to act as a meaningful catalyst for global change, reminding us that ocean health is intricately linked to human health.

During an inflammatory response, things need to happen quickly: ETH Zurich researchers have recently discovered that certain immune cells that function as security guards can use a shortcut to get from the tissue to lymph nodes.

Considered extinct from the Eastern Balkan Mountains of Bulgaria in the 1970s, the Griffon Vulture has claimed the area back with 23-25 breeding pairs, distributed in five different colonies and two more frequently used roosting sites. This astonishing success was achieved through an ambitious long-term restoration programme and the release of 153 vultures between 2010-2020. The research project is described in the open-access, peer-reviewed Biodiversity Data Journal.

Whether it's plankton exposed to parasites or people exposed to pathogens, a host's initial immune response plays an integral role in determining whether infection occurs and to what degree it spreads within a population, new University of Colorado Boulder research suggests.

Using an epigenetic clock, the researchers looked at the genes of 45 of those who were ELBW babies along with 47 who were normal birth weight when they were age 30 to 35 to compare their biological age, controlling for chronic health problems and sensory impairments.

Indigenous peoples in Canada have higher rates of death and complications after surgery and lower rates of surgeries than other populations, found new research published in CMAJ (Canadian Medical Association Journal) http://www.cmaj.ca/lookup/doi/10.1503/cmaj.191682.

While some parents still have reservations about using telemedicine for their kids, the majority were satisfied with the experience, suggest findings from a new national poll.

Researchers at China's Qingdao University have developed a new 'multi-modal' image fusion method based on supervised deep learning. It enhances image clarity, reduces redundant image features and supports batch processing, improving the accuracy of medical diagnoses.

POSTECH research team led by Junsuk Rho presents a nanophotonics-based ultracompact LiDAR technology in a world-renowned journal.

Two research breakthroughs are poised to accelerate the development of synthetic diamond-based quantum technology.

Sperm are generally viewed as having just one action in reproduction -- to fertilize the female's egg - but studies at the University of Adelaide are overturning that view.

In patients who had a coronary stent inserted after experiencing the most severe type of heart attack, the use of a technique that measures blood flow and pressure through a partially blocked artery to determine if a second stenting procedure is needed did not improve outcomes and was more costly than using angiography, or a heart X-ray, alone to guide the procedure, according to research presented at the American College of Cardiology's 70th Annual Scientific Session.

Rivaroxaban, in addition to low-dose aspirin, significantly reduced the occurrence of total severe events of the heart, limb or brain and issues related to other vascular complications in patients with symptomatic peripheral artery disease (PAD) who underwent lower extremity revascularization, a procedure to open blocked arteries in the leg. The findings, presented at the American College of Cardiology's 70th Annual Scientific Session, expand on earlier data and underscore the broad absolute benefits of this strategy in this high-risk patient population, researchers said.

Taking medications to protect the heart from damage associated with adjuvant breast cancer therapy--medications that are administered in addition to surgery to remove a tumor--did not significantly improve markers of heart health two years after breast cancer treatment, according to a study presented at the American College of Cardiology's 70th Annual Scientific Session.

Older patients hospitalized with acute heart failure who participated in a novel 12-week physical rehabilitation (rehab) program tailored to address their specific physical impairments had significant gains not only in physical functioning but also quality of life and depression compared with those receiving usual care, regardless of their heart's ejection fraction, according to a new study presented at the American College of Cardiology's 70th Annual Scientific Session.

Dapagliflozin, a sodium-glucose cotransporter 2 (SGLT2) inhibitor, did not significantly reduce the risk of organ failure or death or improve recovery in patients hospitalized with COVID-19 who are at high risk of developing serious complications compared to placebo, according to data presented at the American College of Cardiology's 70th Annual Scientific Session.

Patients at high risk for cardiovascular events who had the highest levels of eicosapentaenoic acid (EPA) in their blood one year after taking daily omega-3 carboxylic acid, a prescription-grade fish oil, had similar rates of major cardiovascular events as people taking a corn oil placebo, according to a secondary analysis of the STRENGTH trial presented at the American College of Cardiology's 70th Annual Scientific Session.

People with extremely high levels of triglycerides (a type of fat in the blood) and a specific genetic profile saw a substantial reduction in triglycerides after taking the human monoclonal antibody evinacumab compared with those taking a placebo, in a study presented at the American College of Cardiology's 70th Annual Scientific Session.

Among patients who had a cardiac stent inserted after a heart attack, switching to less-potent dual antiplatelet therapy (DAPT) after 30 days was safer and more effective in preventing adverse events a year later than continuing on a high-potency DAPT regimen, according to data presented at the American College of Cardiology's 70th Annual Scientific Session.
