LA JOLLA, CA—The insomnia drug suvorexant (Belsomra®) might be an effective treatment for opioid use disorder, according to a preclinical study from Scripps Research. In the study, published April 27, 2023, in Frontiers in Pharmacology, the Scripps Research scientists found that suvorexant reduced prescription opioid intake and helped protect against relapse in rats modeling opioid use disorder (OUD). If the results translate to humans in clinical trials, the insomnia drug could offer a promising approach for the millions of people who have OUD. “Our results suggest that repurposing suvorexant could be a good strategy for reducing drug intake and blocking relapse in cases ...

From New York to North Carolina and as far west as Illinois, the invasive spotted lanternfly is causing chaos in many states where agricultural and forestry industries are essential to the economy. It has been estimated that crops and forest production losses caused by insects and pathogens are close to $40 billion a year. Spotted laternflies, native to mainland China, prey upon 70-plus host plant species, stealing their nutrients with their piercing snouts, called stylets. They are often characterized as “hitchhikers” for their ability to move ...

Amid rising evidence that additives designed to improve plastics also disrupt sex hormones, a Rutgers laboratory trial shows that plastic itself can do likewise when inhaled at moderate levels. Previous studies focused on chemicals such as bisphenol-A (BPA) that make plastics stiffer or more flexible. These findings spurred ongoing efforts to find safer plastic additives. The Rutgers study showed that microscale and nanoscale particles (MNPs) of polyamide, a common plastic better known as nylon, produced endocrine-disrupting ...

CRISPR claimed scientific fame for its ability to quickly and accurately edit genes. But, at the core, CRISPR systems are immune systems that help bacteria protect themselves from viruses by targeting and destroying viral DNA and RNA. A new study published in Science reveals a previously unrecognized player in one such system – a membrane protein that enhances anti-viral defense – simultaneously broadening our understanding of and raising more questions related to the complexities of CRISPR. Uncovering New Clues about CRISPR CRISPR systems consist of two major components – a guide RNA that targets a specific viral DNA or RNA sequence and a Cas enzyme ...

For millennia, humans have used knots for all kinds of reasons — to tie rope, braid hair, or weave fabrics. But there are organisms that are better at tying knots and far superior — and faster — at untangling them. Tiny California blackworms intricately tangle themselves by the thousands to form ball-shaped blobs that allow them to execute a wide range of biological functions. But, most striking of all, while the worms tangle over a period of several minutes, they can untangle in mere milliseconds, escaping at the first sign of a threat from a predator. Saad Bhamla, assistant ...

New Haven, Conn. — What the human genome is lacking compared with the genomes of other primates might have been as crucial to the development of humankind as what has been added during our evolutionary history, according to a new study led by researchers at Yale and the Broad Institute of MIT and Harvard. The new findings, published April 28 in the journal Science, fill an important gap in what is known about historical changes to the human genome. While a revolution in the capacity to collect data from genomes ...

CHAPEL HILL, N.C. – Hundreds of scientific studies have been conducted over the years to find the genes underlying common human traits, from eye color to intelligence and physical and mental illnesses. Patrick Sullivan, MD, FRANZCP, the Yeargan Distinguished Professor of Psychiatry and Genetics at the UNC School of Medicine, and the Psychiatric Genomic Consortium have produced a new packet for the journal Science, to give researchers another way to understand human disease, using the power of evolutionary genomics. “This is a tool that can give us a lot of important hints about human disease,” ...

Solving a riddle that has confounded biologists since bacterial spores — inert, sleeping bacteria —  were first described more than 150 years ago, researchers at Harvard Medical School have discovered a new kind of cellular sensor that allows spores to detect the presence of nutrients in their environment and quickly spring back to life. It turns out that these sensors double as channels through the membrane and remain closed during dormancy but rapidly open when they detect nutrients. Once open, the channels allow electrically charged ions to flow out through the cell membrane, setting in motion ...

HOUSTON – (April 27, 2023) – Research supports the promise of psychedelics in treating conditions like depression and post-traumatic stress disorder, but the future regulatory landscape for these drugs remains unclear. Experts from Baylor College of Medicine, the University of Pennsylvania, American University and Harvard Law School call for creativity and collaboration at the federal and state levels in developing policies for the use and oversight of psychedelics and a commitment to developing a strong evidence base for efficacy and safety. In a paper published in the journal Science, the authors, experts in bioethics, law and ...

Contrary to what is stated in biology textbooks, the growth of fish doesn’t slow down when and because they start spawning. In fact, their growth accelerates after they reproduce, according to a new article published in Science.   “Fish don’t have to choose between growth or reproduction because, in the real world, they don’t occur simultaneously but rather sequentially,” says University of British Columbia (UBC) fisheries researcher Dr. Daniel Pauly, co-author of ...

Counting problems arise in many different fields, e.g., statistical physics, economics and machine learning. In order to study the complexity of counting problems, several natural frameworks have been proposed. Two well studied frameworks are counting constraint satisfaction problems (#CSP) and Holant problems. For counting satisfaction problems over the Boolean domain, two explicit tractable families namely  and , are identified; any function set which is not contained in these two families is proved to be #P-hard. Furthermore, counting CSPd is the counting constraint satisfaction problem restricted to the instances where every variable occurs a multiple of d times. The team ...

Results from the NRG Oncology RTOG 0631 clinical trial comparing stereotactic vs. conventional radiotherapy for localized vertebral metastases of the spine did not meet its primary endpoint. Data from the study suggests that radiosurgery was not considered superior in terms of pain responses at 3 months following treatment, and even displayed worse pain response, than the conventional external beam radiotherapy (cEBRT). These results were recently published in the JAMA Oncology. cEBRT is currently the standard of care for treating ...

A study supported by the National Institutes of Health found that people who experienced acute kidney injury (AKI) during a hospitalization, including those admitted with AKI or who developed AKI in the hospital, were more likely to revisit the hospital or die shortly after discharge, compared to people hospitalized without AKI. AKI is a sudden loss of kidney function that usually lasts for a short time. The research, funded by NIH’s National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK), was ...

Inflammation is a complex biological process that can eradicate pathogens and promotes repair of damaged tissues. However, deregulation of the immune system can lead to uncontrolled inflammation and produce lesions instead. Inflammation is also involved in cancer. The molecular mechanisms underlying inflammation are not fully understood, and so developing new drugs represents a significant challenge. As far back as 2020, Dr. Raphaël Rodriguez, CNRS research director and head of the Chemical Biology team at Institut Curie (Equipe ...

The importance of alternative energy has recently increased due to global challenges such as environmental ...

FOR IMMEDIATE RELEASE Researchers at Johns Hopkins University School of Medicine say they have evidence from a new study in rats that spinal cord stimulation (SCS) may be useful in reducing chronic pain in people undergoing active treatment with a common anti-cancer drug. The study found that the use of SCS measurably reduced pain response in rats that were implanted with human lung cancer tissue — without compromising effectiveness of treatment with paclitaxel, a drug used to treat a variety of cancers. The study, published April 11 in Neuromodulation: Technology at the Neural ...

Norway, like other Nordic countries, widely utilised non-mandatory advice during the COVID-19 pandemic in the attempt to reduce social contacts among people and occasionally turned to obligatory measures, specifically during peaks in transmission. In comparison with stricter interventions, non-mandatory measures are usually less invasive and costly and have been recommended in previous pandemics, including influenza. Mobile phone data provides mobility metrics In their research article published in Eurosurveillance today, Kamineni et al. compare the impact on mobility when previously non-mandatory ...
