Permanent magnets, the kind found on refrigerators everywhere, exist because their constituent atoms behave as miniature magnets. They align and combine to form the larger magnet in a phenomenon called ferromagnetism. There are some materials where the atomic magnets instead form an alternating pattern, so the material has no net magnetization. Such antiferromagnets have attracted attention for their potential to create faster and more compact magnetic memory devices for computing. Realizing the full potential of antiferromagnetic devices will require sensing their atom-to-atom magnetic patterns, ...

DETROIT (April 12, 2023) – Henry Ford Hospital structural heart interventional cardiologists Pedro Villablanca, M.D., and Brian O’Neill, M.D., are the first in the U.S. to successfully implant the new transcatheter tricuspid valve replacement device LuX-Valve Plus™ for the treatment of patients with symptomatic tricuspid valve disease for whom traditional open-heart surgery is too high of a risk. “These are patients with severe tricuspid regurgitation who have no other options available to them in the U.S., based on the anatomy of their native valve and medical complexities,” ...

Dynamic control of terahertz (THz) waves at-will with an ultracompact device is important for THz technologies in biomedical imaging, telecommunications, detection, and beyond. However, tunable THz devices made of conventional materials are usually bulky, and they tend to have limited modulation depths and functionalities, due to weak interactions between naturally existing materials and THz waves. Metasurfaces – functional materials endowed with unparalleled flexibility to manipulate light at the deep-subwavelength scale – provide ...

Dopamine, a brain chemical long associated with pleasure, motivation and reward-seeking, also appears to play an important role in why exercise and other physical efforts feel “easy” to some people and exhausting to others, according to results of a study of people with Parkinson’s disease led by Johns Hopkins Medicine researchers. Parkinson’s disease is marked by a loss of dopamine-producing cells in the brain over time. The findings, published online April 1 in NPG Parkinson’s Disease, could, the researchers say, eventually lead to more effective ways to help people establish and stick with exercise ...

BOSTON – There were more than 100,000 reported deaths from opioid overdoses in 2021, according to the Centers for Disease Control and Prevention. Methadone treatment remains one of the most reliable means of treating opioid use disorder, with success rates reportedly ranging from 60 to 90 percent for patients who stick with the long-term regimen. Adherence, though, remains a challenge. In a novel randomized clinical trial published in JAMA Network Open, senior author Ted J. Kaptchuk at Beth Israel Deaconess Medical Center ...

ORLANDO, April 12, 2023 – A University of Central Florida researcher will be using the newly constructed Two-meter Twin Telescope (TTT) in the Canary Islands, Spain, to study metal-rich M-type asteroids. The work can inform the study of asteroids like 16 Psyche, an M-type, or metal, asteroid NASA is launching a mission in October 2023 to visit. The M-type asteroids offer both high concentrations of metals that could be harnessed to make structures in space as well as clues to the formation of ...

As the number of children in need of access to timely evaluation and intervention for autism spectrum disorder (ASD) continues to rise, new research is showing how barriers to diagnoses and treatment can be reduced through an innovative training program first developed at the University of Missouri. ASD can be identified and diagnosed in young children by a well-trained clinician, and early diagnosis is vital to quickly establishing access to evidence-based therapies and interventions. However, long specialty center waitlists, distance, and ...

Rutgers geneticists, working with an international team of scientists, have conducted the most comprehensive sequencing yet of the complete DNA sequence of the little skate – which, like its better-known cousin, the stingray, has long been viewed as enigmatic because of its shape. The scientists, writing in Nature, reported that by studying the intricacies of Leucoraja erinacea’s genome, they have gained a far better understanding of how the fish evolved from its ancestor – which possessed a much narrower body – over a period of 300 million years to become a flat, winged bottom-dweller. “We ...

A type of cell usually characterized as the brain’s support system appears to play an important role in obsessive-compulsive disorder-related behaviors, according to new UCLA Health research published April 12 in Nature.  The new clue about the brain mechanisms behind OCD, a disorder that is incompletely understood, came as a surprise to researchers. They originally sought to study how neurons interact with star-shaped “helper” cells known as astrocytes, which are known to provide support and protection to neurons. However, ...

The National Cancer Institute, part of the National Institutes of Health (NIH), has helped launch a phase 3 randomized clinical trial (NCT05633602) of a two-drug combination to treat patients with advanced non-small cell lung cancer (NSCLC). Called the Pragmatica-Lung Study (or S2302), this is one of the first NCI-supported clinical trials to use a trial design that removes many of the barriers that prevent people from joining clinical trials. This “pragmatic” approach aims to increase accessibility ...

Acylceramides and protein-bound ceramides are vital for the formation of the oral barrier in mice, similar to their role in skin, protecting from infection. The skin is the body’s first line of defense against the environment, particularly against pathogens, chemicals, and allergens. It is now known that a class of biological molecules called acylceramides and their metabolites, protein-bound ceramides, are essential to the formation of this barrier. The outermost tissues of the mouth are closely related to the skin and have similar functions—an oral barrier. However, little ...

Washington, DC—Our planet’s water could have originated from interactions between the hydrogen-rich atmospheres and magma oceans of the planetary embryos that comprised Earth’s formative years, according to new work from Carnegie Science’s Anat Shahar and UCLA’s Edward Young and Hilke Schlichting. Their findings, which could explain the origins of Earth’s signature features, are published in Nature. For decades, what researchers knew about planet formation was based ...

Substance use disorder affects 20 million Americans, and more than 100,000 people died from a drug overdose in 2021, according to the Centers for Disease Control and Prevention. While the medication methadone has the strongest evidence-based effectiveness to prevent relapse, about half of patients drop out of their treatment within one year of initiation. The solution could lie in taking a simple “sugar pill” or placebo along with the methadone, according to a randomized clinical trial led by researchers at the University of Maryland School of Medicine. In a randomized ...

Liver cancer is the third leading cause of cancer death and the sixth most common cancer type worldwide. Major risk factors include environmental and metabolic stressors, such as obesity, viral hepatitis and steatohepatitis (fatty and inflamed liver). These stressors damage the liver by killing hepatocytes, the major cell type in the liver. The cell death then triggers an inflammatory response which signals the liver to generate a new batch of hepatocytes. But this sudden push towards cellular proliferation also increases the risk of tumor formation. In ...

Yin-Yang theory is an ancient Chinese philosophy in which Yin-Yang forces are interdependent and work in opposition to each other to create balance. Recently, inspired by this ancient theory, a research team led by Prof. GUO Xin and Prof. LI Can from the Dalian Institute of Chemical Physics (DICP) of the Chinese Academy of Sciences (CAS) has revealed the origin of the stability of Dion–Jacobson (DJ) phase two-dimensional (2D) perovskite materials. Their findings were published in Joule on April 12. DJ 2D perovskites, a class of organic–inorganic ...

CAMBRIDGE, MA -- Human skin is home to millions of microbes. One of these microbes, Staphylococcus aureus, is an opportunistic pathogen that can invade patches of skin affected by eczema, also known as atopic dermatitis. In a new study, researchers at MIT and other institutions have discovered that this microbe can rapidly evolve within a single person’s microbiome. They found that in people with eczema, S. aureus tends to evolve to a variant with a mutation in a specific gene that helps it grow faster on the skin. This study marks ...

PLYMOUTH MEETING, PA [April 12, 2023] — The NCCN 2023 Annual Conference took place in-person in Orlando and virtually, with a particular focus on human connection. That connection was underscored with more than 2,000 registrants from across the continuum of cancer care, including approximately 1,000 who returned in-person for the first time since 2019. Educational sessions highlighted the importance of ensuring care meets the latest standards while also rejecting a one-size-fits-all approach. “At NCCN, we don’t shy away from difficult discussions; we want our conference attendees to take away the message that ...

Have you ever wondered why some insects like cockroaches prefer to stay or decrease movement in darkness? Some may tell you it’s called photophobia, a habit deeply coded in their genes. A further question would be whether we can correct this habit of cockroaches, that is, moving in the darkness just as they move in bright backgrounds. Scientists from Osaka University may have answered this question with a positive answer. They solved this question by converting a cockroach into a cyborg. They published this research in the journal Cyborg and Bionic Systems.                  ...
