The research was based on pulsar timing observations carried out with the Five-hundred-meter Aperture Spherical Telescope (FAST). The research was conducted by the Chinese Pulsar Timing Array (CPTA) collaboration. Researchers (Prof. Kejia Lee, Post-Doc. Siyuan Chen, PhD students Jiangwei Xu, and Zihan Xue) from Department of Astronomy ...

EAST LANSING, Mich. – Women with a history of endometriosis had higher concentrations of cadmium in their urine compared to those without that diagnosis, according to a Michigan State University study that suggests the toxic metal could be linked to the development of endometriosis.  Affecting one in 10 reproductive-age women, endometriosis is a gynecologic condition in which tissue that looks like the lining of the uterus, or womb, appears outside the uterus. Those with endometriosis can experience chronic, painful and debilitating symptoms, which can interfere with all aspects of life, including daily activity, work productivity, ...

Ann Arbor, July 24, 2023 - Among nearly 10 million US infants born between 2016 and 2018, breastfed babies were 33% less likely to die during the post-perinatal period (day 7−364) than infants who were not breastfed, reports a new study in the American Journal of Preventive Medicine, published by Elsevier. The findings build on previous US research with smaller datasets, which documented the association between the initiation of breastfeeding and the reduction of post-perinatal infant mortality by a range of 19% to 26%. Lead investigator Julie L. Ware, MD, MPH, ...

An analysis of real-world data from more than 1.2 million patients from health systems in four geographically dispersed states -- Indiana, Oregon, Texas and Utah -- conducted by the U.S. Centers for Disease Control and Prevention’s VISION Network, has determined both the number of adults needed to be vaccinated to prevent one COVID-19 associated hospitalization and the number needed to be vaccinated to prevent one COVID-19 associated emergency department (ED) visit. This study is one of the first, ...

A new study involving over 700,000 U.S. veterans reports that people who adopt eight healthy lifestyle habits by middle age can expect to live substantially longer than those with few or none of these habits. The eight habits are: being physically active, being free from opioid addiction, not smoking, managing stress, having a good diet, not regularly binge drinking, having good sleep hygiene, and having positive social relationships.   According to the results, men who have all eight habits at age 40 would be predicted to live an average of 24 years longer than men with none of these habits. For women, having all eight healthy lifestyle factors ...

More people are drinking milk alternatives made from plant sources such as oats, soy, or almonds, but do plant-based products deliver the same nutrition as cow’s milk? Results from a new study suggest that most don’t.   Cow’s milk is an important source of calcium and vitamin D, both of which are identified in the 2020-2025 Dietary Guidelines for Americans as nutrients of public health concern for underconsumption. Cow’s milk is also a major source of protein in the American diet.   To assess how the nutritional content of plant-based milk alternatives compares to that of cow’s milk, researchers examined more than ...

COLUMBUS, Ohio – When people who publicly reject COVID-19 vaccines later die from the disease, observers have complex reactions to their fates, a new study suggests.   While very few rejoice in the deaths of anti-vaxxers, some people believe those who are dogmatic against vaccines are deserving of worse outcomes – and that reaction is related to the political party affiliation and vaccination status of the person evaluating the anti-vaxxer.   Democrats and those who were vaccinated were more likely than Republicans and the unvaccinated to think anti-vaxxers who died got what they deserved ...

As artificial intelligence expands across more professions, robot preachers and AI programs offer new means of sharing religious beliefs, but they may undermine credibility and reduce donations for religious groups that rely on them, according to research published by the American Psychological Association.   “It seems like robots take over more occupations every year, but I wouldn’t be so sure that religious leaders will ever be fully automated because religious leaders need credibility, and robots aren’t credible,” said lead researcher Joshua Conrad Jackson, PhD, an assistant professor at the University of ...

July 24, 2023 – Characters with facial disfigurement have long been a recurring theme in films. Their characteristics and outcomes lend insights into perceptions of facial deformities and the effects of plastic surgery, reports a study in The Journal of Craniofacial Surgery under the guidance of Editor-in-Chief Mutaz B. Habal, MD, FRCS, FACS of Tampa, Florida. The journal is published in the Lippincott portfolio by Wolters Kluwer. Movie characters who undergo successful plastic surgery to improve their facial appearance are more likely to have happy endings, according to the new research by Young Suk Kim, BA, and Kun Hwang, MD, PhD, of Armed Forces ...

A new study suggests that incorporating olive oil into your diet could help reduce the risk of dying from dementia. As many countries face rising rates of Alzheimer’s disease and other forms of dementia, the study offers hope that healthy lifestyle factors such as diet can help to prevent or slow the progression of these devastating conditions.   “Our study reinforces dietary guidelines recommending vegetable oils such as olive oil and suggests that these recommendations not only support heart health but potentially brain health, as well,” said Anne-Julie Tessier, RD, PhD, a postdoctoral fellow at the Harvard T.H. ...

Researchers report that blood levels of the omega-3 fatty acid docosahexaenoic acid (DHA) were inversely correlated with hearing difficulty in a new population-based cross-sectional study. Middle-aged and older adults with higher DHA levels were 8-20% less likely to report age-related hearing issues than those with lower DHA levels.   “Higher DHA levels have previously been found to be associated with a lower risk of heart disease, cognitive impairment, and death. Our study extends these findings to suggest a role for DHA in maintaining ...

Losing weight is often a goal for people with type 2 diabetes, which is strongly associated with being overweight or obese. However, it hasn’t been clear what dieting strategy works best for people with this metabolic disorder.   A new randomized controlled study of people with type 2 diabetes showed that study participants who restricted eating to between noon and 8 p.m. daily lost more weight than those who reduced their overall calorie intake by counting calories. Both dieting strategies produced similar improvements in blood sugar levels.   “Many people find counting calories very hard to stick to in the long term, ...

Caecilians are an elusive type of amphibian that primarily live underground and look like a cross between a worm and a snake. One of the few things that is known about caecilians is their unique method for feeding their young. Mothers produce a special layer of fatty skin tissue, which juvenile caecilians tear off with baby teeth that evolved specifically for that purpose. A new study shows that skin-feeding does more than provide nutrients for young caecilians. It also helps the mother pass microbes from her skin and gut down to her young, inoculating them to jump-start a healthy ...

A technique that uses imaging technology as a guide can make radiation therapy safer for patients with prostate cancer by helping clinicians accurately aim radiation beams at the prostate while avoiding nearby tissue in the bladder, urethra, and rectum. That is the finding of a thorough analysis of all published clinical trials of the technique, called magnetic resonance–guided daily adaptive stereotactic body radiotherapy (MRg-A-SBRT). The analysis is published by Wiley online in CANCER, a peer-reviewed journal of the American Cancer Society. By providing detailed images, MRg-A-SBRT can be used to adjust a patient’s radiation plan every ...

Children and adolescents living in food-insecure households had a 55% higher frequency of physician visits for mental health reasons than those with adequate food supplies, according to new research published in CMAJ (Canadian Medical Association Journal) https://www.cmaj.ca/lookup/doi/10.1503/cmaj.230332. In 2021, almost 6 million people Canada, including 1.4 million children and adolescents younger than 18 years faced food insecurity; that is, inadequate food intake because of financial problems. The study looked at population health survey data from the Canadian Community Health Survey on ...

Teleost fish encompass a diverse group, among which seahorses display a unique morphology. The characteristic spines and brood pouch seen in seahorses feature distinctive epithelial cells—called flame cone cells—covered by a mucous cap. However, these cells are not found in the barbed pipefish Urocampus nanus or the seaweed pipefish Syngnathus schlegeli, close relatives of the seahorse, belonging to the Syngnathidae lineage. While research has hypothesized the function of the flame cone cells, their evolutionary origins have remained a mystery. Now, a team of scientists led by Assoc. Prof. Mari Kawaguchi and Prof. Shigeki Yasumasu from the Department of Materials ...

According to an analysis of the UK’s cosmetic injectables industry by UCL researchers, 68% of cosmetic practitioners who are administering injections such as Botox are not qualified medical doctors. The study, published in the Journal of Plastic, Reconstructive & Aesthetic Surgery, is the first survey of who is providing cosmetic injectable services, such as Botulinum Toxin (Botox) and Dermal Fillers, in the UK. Currently, little is known about the background qualifications, training and experience levels of those who are administering treatments. To fill this ...

3D printing of complex objects typically takes a long time due to the printing process necessarily laying down a large number of 2D layers to build up the object. The process usually wastes a lot of material required to support the unfinished object. Some novel ways to make flat materials self-fold into 3D shapes exist, but have shortcomings. For the first time, researchers combined 2D printing, origami, and chemistry to create a method of rapid 3D object fabrication without creating any waste material. These shapes self-fold in seconds. For some time, 3D printing has been used to prototype ...

A diet originally designed to help ward off cognitive decline in adults might also help improve attention in pre-adolescents, according to a new study. The findings could help inform future dietary interventions aimed at improving cognition in children.   The new study examined two diets: the Healthy Eating Index – 2015 (HEI-2015), which is based on the Dietary Guidelines for Americans, and the Mediterranean-DASH Intervention for Neurodegenerative Delay (MIND) diet, which combines the Mediterranean diet with the heart-healthy Dietary Approaches to Stop Hypertension ...

Eating more planet-friendly foods could help you live a longer, healthier life, according to new research. Researchers found that people who followed a more environmentally sustainable diet were 25% less likely to die during a follow-up period of over 30 years compared to those with a less sustainable diet.   The study builds upon prior research that identified foods that are a win-win for both health and the environment—such as whole grains, fruit, non-starchy vegetables, nuts, and unsaturated oils—as well as foods that could be harmful to the environment and human health, like eggs ...

A study of over 10,000 children in rural Pennsylvania revealed that a large proportion of children were fed foods that are high in sugar and salt in their first years of life.   Over half (53%) of the children in the study received high-sodium meats such as hot dogs, 37% received salty snacks such as potato chips, and one-third (34%) received cakes, cookies, or pudding before age 2. In addition, over one-quarter (27%) of babies received juice before their first birthday.    “Given ...

Systematic review of 8 studies in more than 7,700 serodiscordant couples in 25 countries finds people living with HIV with viral loads less than 1,000 copies/mL have almost zero risk of transmitting the virus to their sexual partners. Previous studies have not been able to confirm a lack of transmission risk above 200 copies/mL. Systematic review also consolidates and reinforces previous studies that have found there is zero risk of transmitting the virus to sexual partners when people living with HIV have an undetectable viral load. Of the more than 320 documented sexual HIV transmissions ...

In one of the first large-scale studies of genes related to diet, researchers have uncovered almost 500 genes that appear to directly influence the foods we eat. The findings represent an important step toward using a person’s genetics to develop precision nutrition strategies that help improve health or prevent disease.   “Some genes we identified are related to sensory pathways — including those for taste, smell, and texture — and may also increase the reward response in the brain,” said research team leader Joanne Cole, PhD, assistant professor in the Department ...

There is growing evidence that consuming prebiotics — certain types of fiber often found in plants that stimulate beneficial bacteria in your gut — can help to maintain a healthy gut microbiome. In a new study, scientists estimated the prebiotic content of thousands of food types by using preexisting literature to find out which foods offer the highest prebiotic content.   According to the study, foods that pack the greatest prebiotic punch are dandelion greens, Jerusalem artichokes, garlic, leeks, and onions. In addition to supporting gut microbes, prebiotic rich ...

A University of Texas at Arlington engineering researcher is working on defenses that could thwart cyberattacks against networks of self-driving cars and unmanned aerial vehicles. Animesh Chakravarthy, associate professor in the Department of Mechanical and Aerospace Engineering (MAE), is the principal investigator on an approximately $800,000 U.S. Department of Defense grant titled “Resilient Multi-Vehicle Networks.” MAE Professor Kamesh Subbarao, and Bill Beksi, assistant professor ...
