About The Study: The findings of this study of more than 500,000 children suggest that there is no evidence of a difference in math and reading scores over grades 2 to 11 among children born between 39 and 40 weeks’ gestation, and overall no evidence of better scores among those born at 41 weeks’ gestation compared with 40 weeks’ gestation. The results can further inform decisions on delivery timing at term birth by offering insights into long-term associations of delivery timing with cognitive development and school achievement.  Authors: George L. Wehby, M.P.H., Ph.D., of ...

Using energy from light to activate natural enzymes can help scientists create new-to-nature enzymatic reactions that support eco-friendly biomanufacturing — the production of fuels, plastics, and valuable chemicals from plants or other biological systems. Applying this photoenzymatic approach, researchers have developed a clean, efficient way to synthesize crucial chemical building blocks known as chiral amines, solving a longstanding challenge in synthetic chemistry. The study, published in Nature Catalysis, ...

Many substances change their properties when they are cooled below a certain critical temperature. Such a phase transition occurs, for example, when water freezes. However, in certain metals there are phase transitions that do not exist in the macrocosm. They arise because of the special laws of quantum mechanics that apply in the realm of nature’s smallest building blocks. It is thought that the concept of electrons as carriers of quantized electric charge no longer applies near these exotic phase transitions. Researchers at the University of Bonn and ETH Zurich have now ...

(Boston)—In the face of ongoing political threats to the rights and well-being of sexual and gender minority (SGM) populations, public health and health care institutions and practitioners must explicitly address the needs of marginalized populations while ensuring that those with multiple marginalized identities are well represented in research, according to a commentary in JAMA Network Open.  “If we continue to exclude SGM in research, we will remain oblivious to the troubles they face in achieving health and well-being,” said lead author Carl G. Streed, Jr., MD, MPH, FACP, ...

An article to be published on July 31 in Nature Ecology & Evolution reveals that Luzio, the oldest human skeleton found in São Paulo state (Brazil), was a descendant of the ancestral population that settled the Americas at least 16,000 years ago and gave rise to all present-day Indigenous peoples, such as the Tupi. Based on the largest set of Brazilian archeological genomic data, the study reported in the article also offers an explanation for the disappearance of the oldest coastal communities, who built the icons of Brazilian archeology known as sambaquis, huge mounds of shells and fishbones used as dwellings, cemeteries and territorial boundaries. Archeologists often ...

The first bees evolved on an ancient supercontinent more than 120 million years ago, diversifying faster and spreading wider than previously suspected, a new study shows. Led by Washington State University researchers, the study provides a new best estimate for when and where bees first evolved. Newly published in the journal Current Biology, the project reconstructed the evolutionary history of bees, estimated their antiquity, and identified their likely geographical expansion around the world. The results indicate their point of origin was in western Gondwana, an ancient supercontinent that at that time included today's continents of Africa and South America. “There’s ...

What makes a brilliant scientist? Who are the people behind the greatest discoveries of our time? Connecting art and science, photographer Herlinde Koelbl seeks the answers in this English translation of the German book Fascination of Science, an indelible collection of portraits of and interviews with sixty pioneering scientists of the twenty-first century. Koelbl's approach is intimate and accessible, and her highly personal interviews with her subjects reveal the forces (as well as the personal quirks) that motivate the scientists' work; for example, one wakes up at 3 am because ...

CHAMPAIGN, Ill. — Scientists have identified a protein that plays a pivotal role in the action of several emerging cancer therapies. The researchers say the discovery will likely aid efforts to fine-tune the use of immunotherapies against several challenging cancers. They report their findings in the journal Cancer Research.  “Most anticancer drugs cause cancer cells to shrivel up and die in a controlled process known as apoptosis. But apoptosis does not usually strongly activate immune cells,” said David Shapiro, a professor ...

FOR IMMEDIATE RELEASE A new review paper co-authored by two Johns Hopkins pain experts suggests that scrambler therapy, a noninvasive pain treatment,  can yield significant relief for approximately 80%–90% of patients with chronic pain, and it may be more effective than another noninvasive therapy: transcutaneous electrical nerve stimulation (TENS). The write-up was published online July 13 in The New England Journal of Medicine. Scrambler therapy, approved by the U.S. Food and Drug Administration in 2009, administers electrical stimulation through the skin via electrodes placed in areas of the body above and below where chronic pain is felt. The goal is to capture the nerve endings ...

New York, NY (July 31, 2023)—Psychosocial stress profoundly affects people’s lives globally, not least because it can be a critical risk factor for cardiovascular disease. Thanks to an $11.5 million award renewal from the National Heart, Lung, and Blood Institute (NHLBI) of the National Institutes of Health, distinguished researchers at the Icahn School of Medicine at Mount Sinai and elsewhere aim to gain a deeper understanding of how stress influences cardiovascular health. “To address residual cardiovascular risk in patients, our research program aims to bolster our mechanistic understanding ...

You know that freeze-ray gun that “Batman” villain Mr. Freeze uses to “ice” his enemies? A University of Virginia professor thinks he may have figured out how to make one in real life. The discovery – which, unexpectedly, relies on heat-generating plasma – is not meant for weaponry, however. Mechanical and aerospace engineering professor Patrick Hopkins wants to create on-demand surface cooling for electronics inside spacecraft and high-altitude jets. “That’s the primary problem right now,” Hopkins said. “A lot of electronics on board heat up, but they have no way to cool down.” The U.S. Air Force likes the prospect of a freeze ...

PULLMAN, Wash. –The origin of bees is tens of millions of years older than most previous estimates, a new study shows.  A team led by Washington State University researchers traced the bee genealogy back more than 120 million years to an ancient supercontinent, Gondwana, which included today’s continents of Africa and South America. In a study that proposes a new evolutionary history of bees, the researchers found evidence that bees originated earlier, diversified faster and spread wider than many scientists previously suspected. They published their findings in the journal Current ...

Research Highlights: An analysis of data from seven studies involving more than 19,000 adults in the United States, Korea and Japan found a clear association between increases in systolic (top-number) blood pressure and the number of alcoholic beverages consumed daily. Even people who drank one alcoholic beverage per day showed a link to higher blood pressure when compared to non-drinkers, reinforcing the American Heart Association’s advice to limit alcohol intake and to not start drinking alcohol if you do not already. Embargoed until ...

A new study from Tulane University has identified a new treatment for a chronic immune system disease that can prevent children from eating. Eosinophilic esophagitis (EoE) is triggered by food allergies or airborne allergens which causes a type of white blood cell, eosinophils, to build up in the lining of the esophagus. This causes the esophagus to shorten and the esophageal wall to thicken, making swallowing difficult and causing food to get stuck in the throat. The disease occurs in an estimated 1 in 2,000 adults but more frequently affects children (1 in 1,500) where symptoms can be harder to diagnose and pose greater risks as difficulty feeding can lead to malnutrition, weight loss and ...

Postpartum prescriptions for oxycodone were not associated with increased risk of longer-term opioid use compared to codeine prescriptions, according to new research published in CMAJ (Canadian Medical Association Journal) https://www.cmaj.ca/lookup/doi/10.1503/cmaj.221351. Over the last 10 years, there has been a shift to fewer codeine prescriptions and an increase in prescriptions for stronger opioids, such as hydrocodone, hydromorphone and oxycodone for patients postpartum. “This occurred in part ...

Research Highlights: A novel vaccine that targets a protein involved in Alzheimer’s disease helped eliminate toxic cells in mice with the condition. After vaccination, the mice had fewer amyloid plaques and less inflammation in brain tissue and showed improvement in behavior and awareness. Embargoed until 12 p.m. CT/1 p.m. ET, Sunday, July 30, 2023 BOSTON, July 30, 2023 — A novel vaccine that targets inflamed brain cells associated with Alzheimer’s disease may hold the key to potentially preventing or modifying the course of the disease, according to preliminary research presented at the American Heart Association’s Basic Cardiovascular Sciences Scientific ...

Tokyo, Japan – Researchers from Tokyo Metropolitan University have uncovered the physics behind how foams are spread on surfaces. Balls of foam placed on a flat substrate were scraped across with a plate and observed. They identified different patterns which strongly depend on the scraping speed, governed by competing physical phenomena. Their findings apply to all kinds of soft materials that need to be spread evenly on surfaces, from mayonnaise on bread to insulation on walls.   Whether ...

Whether it’s setting up a Bank of England-type body to run it or fining patients for missing appointments, healthcare leaders, policymakers and practitioners past and present have a wealth of ideas about how they would change the NHS for the better. Professor Dinesh Bhugra, a psychiatrist and former president of the British Medical Association and the Royal College of Psychologists, asked 14 peers, physicians and patients’ representatives for their prescription for the NHS. The interviews are reproduced in Professor Bhugra’s new book, Conversations about the NHS.  Thought-provoking and in some cases, controversial, ideas include: Setting ...

As with many toxins, exposure to the toxic metal cadmium during pregnancy can adversely impact fetal development. Now, researchers at the Rutgers School of Public Health think they’re beginning to understand how the metal inflicts its damage: by disrupting placental hormones that regulate pregnancy physiology.   Unlike other toxins, relatively little cadmium crosses the placenta to directly impact the fetus. Instead, the placenta concentrates cadmium in its tissue at rates of up to six times that found in umbilical cord serum.   “We already know a lot about cadmium and its detrimental impacts on fetal health, such ...

A new study by scientists at the Jean Mayer USDA Human Nutrition Research Center on Aging (HNRCA) at Tufts University suggests that a micronutrient in human breast milk provides significant benefit to the developing brains of newborns, a finding that further illuminates the link between nutrition and brain health and could help improve infant formulas used in circumstances when breastfeeding isn’t possible. The study, published July 11 in the Proceedings of the National Academy of Sciences (PNAS),  also paves the way to study what role this micronutrient might play in the brain as ...
