UC San Diego study identifies new potential treatment targets for COVID-19 and other diseases caused by coronaviruses.
Determining whether one variable truly causes another – rather than merely correlating with it – usually requires deliberate intervention experiments, which are often impossible in climate systems, neural circuits, or economies. Reporting in The Innovation, researchers led by Professors Wei Lin, Luonan Chen, and Kazuyuki Aihara introduce a theoretical framework called interventional dynamical causality (IntDC) together with a computational criterion, interventional embedding entropy (IEE). Built on delay-embedding state-space reconstruction, IEE quantifies the strength of intervention-level causal effects using observational time-series data alone – no manipulation of the system required. The method accurately removed confounding effects in benchmark simulations and successfully reconstructed the neural connectome of Caenorhabditis elegans, COVID-19 transmission networks in Japan, and circadian gene regulatory networks.

Early Paxlovid treatment was associated with modestly lower risks of Long COVID, post-acute hospitalization, and death among high-risk, nonhospitalized patients with COVID-19, while no clear reduction in Long COVID risk was observed among low-risk patients.
A new national study found that hospitalizations for serious heart infections associated with drug use are declining after years of increases, driven largely by a decrease in opioid-associated cases.
Published today in Clinical Infectious Diseases, the study analyzed national hospitalization data from 2016 through 2022 to identify trends in drug use-associated infective endocarditis. Researchers identified more than 118,000 hospitalizations nationwide during the seven-year period. Hospitalizations peaked at approximately 18,700 in 2020, during the COVID-19 pandemic, before declining by 18% to about 15,300 in 2022.
Infective endocarditis is a potentially life-threatening infection that occurs when bacteria or other germs enter the bloodstream and infect the inner lining or valves of the heart. The infection, which can occur when people inject drugs, can cause permanent heart damage, require lengthy hospital stays or lead to death.
Stimulants outnumbered opioid cases in parts of the country
The researchers also pointed out another key finding: while opioid-associated hospitalizations are declining, stimulants such as methamphetamine and cocaine are accounting for a growing share of these serious infections, particularly in the Western part of the United States.
The researchers estimated a 59% probability of stimulant-involved infective endocarditis in the Pacific region, compared to 34% in New England.
Nationwide, in 2016, approximately 37% of drug use associated endocarditis hospitalizations involved stimulants, either alone or in combination with opioids. By 2022, that proportion had increased to nearly 47%.
“I believe the problem isn't simply that stimulants are becoming more prominent. It's that the healthcare system currently has fewer effective tools to treat stimulant use disorder than opioid use disorder,” said Christine.
Suicidal ideation increased 42.6%, suicide planning by 256.2% and suicide attempts by 263.3% among older U.S. adults from 2021-2024, according to a new UCLA Health and UC San Diego Health study.
Research published in the Journal of Risk and Financial Management shows that crises do more than cause financial market volatility and falling share prices – they lead to markets becoming far more interconnected.
The study examined the Dow Jones Industrial Average, S&P 500, FTSE 100 and DAX during the Global Financial Crisis and the Covid-19 pandemic.
Rather than study correlation (market A causes a movement in market B), the research used a technique derived from chaos theory, known as convergent cross-mapping, to look at whether the dynamics of one market contained recoverable information about another.
The most striking results came from the Covid-19 pandemic, where the average coupling measure increased by 16% from pre-crisis to crisis period.Routine vaccine program disruptions and under-resourced health systems are driving a global decline in childhood measles vaccination rates post COVID-19, a study has found.
In the early days of the COVID-19 pandemic, many households wiped down groceries with disinfectant before putting them away. Hand sanitizer was in short supply. With little information on how the virus spread – people became more cautious of germs from other people. A new University of California San Diego study suggests that humans may not be alone in changing behavior after experiencing a disease threat.
Researchers examining whether COVID-19 vaccination affects persistent smell or taste problems after contracting the virus have found that, in most cases, it does not.
