The restoration of mussel beds in the Wadden Sea or the Delta is a lot more successful when young mussels are helped a little with low, protective fences on the bottom. That is shown by research conducted by marine biologist Jildou Schotanus at the Hogeschool Zeeland / University of Applied Sciences in Vlissingen and at the Royal Netherlands Institute for Sea Research in Yerseke. She defends her thesis Restoring mussel beds on highly dynamic mudflats at the University of Groningen on Monday February 5th. Ecosystem engineers Mussels are so-called ecosystem ...

Although most patients diagnosed with Covid-19 will quickly recover, some people experience symptoms that linger well after they start testing negative again — including insomnia. Scientists already knew that insomnia was common in patients who had to be hospitalized, but a team of scientists led by Dr Huong T. X. Hoang of Phenikaa University, Vietnam began to wonder if mild infections might also affect sleep quality. “As a sleep researcher, I received many questions and complaints from relatives, friends, ...

How can inclusivity be achieved in cardiopulmonary exercise tests for individuals facing lower limb injuries or disabilities that make it impossible to pedal a bicycle? Conventional exercise assessments rely primarily on lower limb exercise to determine maximal oxygen uptake – a cardiopulmonary function metric that indicates the maximum amount of oxygen that can be taken into the body in one minute. If lower limbs cannot be exercised, it necessitates an upper limb alternative. However, no clear upper limb ...

With more than 100,000 drug overdose deaths in the United States in one year, communities need more than ‘just say no’ drug prevention education and abstinence-only addiction treatment to save lives, an expert has warned. Statistics show that most people who complete conventional drug prevention education as youth eventually go on to use alcohol, nicotine, or illegal drugs. Harm reduction expert Sheila P. Vakharia, PhD, MSW, explains: “The majority have experimented, others use socially, and some experience substance-related problems or addictions. And, regardless of their patterns of use, most have never been taught strategies for safer substance use, ...

An article published in CMAJ (Canadian Medical Association Journal) describes five things clinicians and harm reduction workers should know about xylazine, a veterinary medication adulterating the illicit opioid supplyhttps://www.cmaj.ca/lookup/doi/10.1503/cmaj.231603. There is no antidote to the effects of xylazine, and the authors explain that xylazine contamination should be suspected when naloxone appears not to work effectively in people with opioid toxicity. Highlights: Xylazine is not approved for use in humans and is increasingly found in illicit drug samples along with fentanyl. People using ...

Children and young adults with allergies or eczema who have difficulty swallowing may have eosinophilic esophagitis. A review published in CMAJ (Canadian Medical Association Journal) provides guidance on how to diagnose and manage this chronic inflammatory disease https://www.cmaj.ca/lookup/doi/10.1503/cmaj.230378. In people with eosinophilic esophagitis, the esophageal lining is inflamed, which can cause injury and narrowing of the throat. Although it can affect anyone, the risk is higher in children aged 5–14 years ...

Pancreatic cancer is the No. 3 cause of cancer-related deaths in the United States, and only 12% of patients survive five years after being diagnosed. Severe pancreatic cancer is associated with metastasis, and it is this spread of secondary tumors that usually causes death, but little is known about the molecular mechanisms that drive metastasis. In a study published Dec. 18 in Advanced Science, researchers from the University of California, Davis showed that abnormal expression of the protein Engrailed-1 (EN1) ...

Food manufacturers often add preservatives to food products to keep them fresh. A primary purpose of these preservatives is to kill microbes that could break down and otherwise spoil the food. Common additives like sugar, salt, vinegar and alcohol have been used as preservatives for centuries, but modern-day food labels now reveal more unfamiliar ingredients such as sodium benzoate, calcium propionate, and potassium sorbate. Bacteria produce chemicals called bacteriocins to kill microbial competitors. These chemicals can serve as natural preservatives by killing potentially dangerous pathogens ...

Many people are familiar with facial recognition systems that unlock smartphones and game systems or allow access to our bank accounts online. But the current technology can require boxy projectors and lenses. Now, researchers report in ACS’ Nano Letters a sleeker 3D surface imaging system with flatter, simplified optics. In proof-of-concept demonstrations, the new system recognized the face of Michelangelo’s David just as well as an existing smartphone system. 3D surface imaging is a common tool used in smartphone facial recognition, as well as in computer vision and autonomous driving. These systems typically consist of a dot projector that contains multiple components: ...

Many complex systems, from microbial communities to mussel beds to drylands, display striking self-organized clusters. According to theoretical models, these groupings play an important role in how an ecosystem works and its ability to respond to environmental changes. A new paper in PNAS focused on the spatial patterns found in drylands offers important empirical evidence validating the models. Drylands make up 40 percent of the Earth’s landmass and are places where water is the limiting resource for life. They often display a characteristic ...

DURHAM, N.C. – As the HIV virus glides up outside a human cell to dock and possibly inject its deadly cargo of genetic code, there’s a spectacularly brief moment in which a tiny piece of its surface snaps open to begin the process of infection. Seeing that structure snap open and shut in mere millionths of a second is giving Duke Human Vaccine Institute (DHVI) investigators a new handle on the surface of the virus that could lead to broadly neutralizing antibodies for an AIDS vaccine. Their findings appear Feb. 2 in Science Advances. Being able to attach an antibody specifically to ...
