BOSTON—Plant-based proteins have major health advantages over animal-based proteins, according to a New England Journal of Medicine letter to the editor by Neal D. Barnard, MD, published Aug. 1, 2024. New findings show that all plants contain all essential amino acids, in contrast to the common but mistaken belief that plants lack one or more amino acids. Of the 20 amino acids that are the building blocks of protein, nine cannot be produced by the human body. All are found in plant sources. “In addition, plant-based ...

HOUSTON – (August 1, 2024) – Materials behave differently in different size regimes, and researchers tend to cluster their efforts either at the nanoscale, examining materials in atom-level detail, or at the microscale, looking at structures between three and five orders of magnitude greater. However, less is known about what happens in the “in-between” realm spanning from 10 billionths to 1 millionth of a meter. “We call this the mesoscale,” said Rice University materials scientist Lane Martin, who together with collaborators at the U.S. Department of Energy’s (DOE) Argonne National Laboratory and Lawrence Berkeley National ...

During the height of the COVID-19 pandemic Gregory Berns, a neuroscientist at Emory University, moved from Atlanta to a farm an hour south of the city. His reinvention from city dweller to farmer led to his upcoming book “Cowpuppy: An Unexpected friendship and a Scientist’s Journey into the Secret World of Cows.” Set for publication by Harper Collins on August 20, the book describes Berns’ crash course to becoming a cattleman and his ongoing fascination with the interior world of cows. Berns originally bought a few cows to keep the grass in the ...

Hotter conditions prevent two tiny organisms working together for mutual benefit, new research shows. University of Exeter scientists studied a single-celled organism (Paramecium bursaria) which can absorb and host algae (Chlorella spp). This pairing is common in freshwater worldwide, and their symbiotic relationship provides benefits including trading of nutrients and protection for the algae. But when scientists made the water 5°C warmer, the partnership stopped working – and the results suggest the algae may even become parasitic. The breakdown of such relationships could have a major impact on ecosystems. “This ...

Despite widespread support, laws enforcing universal background checks at the time of firearm purchase may not be enough to move the needle on reducing shooting deaths in the United States. A Tufts University School of Medicine study, published August 1 in the journal JAMA Network Open, reports that states that require gun permits rather than relying solely on universal background checks see firearm homicide rates, on average, 18% lower than states with background check policies alone. The analysis compared firearm homicide data from the 12 states with universal background check laws but no permit ...

Regular aspirin may help lower risk of colorectal cancer in people with greater lifestyle-related risk factors for the disease, according to a study led by researchers at Mass General Brigham. The study, published in JAMA Oncology, could encourage a more nuanced approach to preventive aspirin use. “We sought to identify individuals who are more likely to benefit from aspirin to facilitate more personalized prevention strategies,” said co-senior author Andrew Chan, MD, MPH, Director of Epidemiology for the Mass General Cancer Center and gastroenterology Director of the Center for ...

About The Study: Between 14 and 27 weeks’ gestation, novice users with no prior training in ultrasonography estimated gestational age as accurately with the low-cost, point-of-care artificial intelligence (AI) tool as credentialed sonographers performing standard biometry on high-specification machines. These findings have immediate implications for obstetrical care in low-resource settings, advancing the World Health Organization goal of ultrasonography estimation of gestational age for all pregnant people. Quote from corresponding author Jeffrey ...

About The Study: Aspirin use was associated with a greater absolute reduction in risk of colorectal cancer among individuals with less healthy lifestyles in this cohort study.

About The Study: In this purposive national survey study of clinicians providing abortion, moral distress was elevated among all clinicians and more than twice as high among those practicing in states that restrict abortion compared with those in states that protect abortion. The findings suggest that structural changes addressing bans on necessary health care, such as federal protections for abortion, are needed at institutional, state, and federal policy levels to combat widespread moral distress.  Corresponding Author: To contact the corresponding author, ...

About The Study: This cross-sectional study found that universal background checks alone were not associated with firearm homicide rates, but a permit requirement for the purchase and possession of firearms was associated with substantially reduced rates of firearm homicide. The findings suggest that combining universal background checks and permit-to-purchase requirements is an effective strategy for firearm-related fatality reduction.  Corresponding Author: To contact the corresponding author, Michael Siegel, MD, MPH, email mike.siegel@tufts.edu.

Fewer side effects, improved chances of healing: the goal of precision medicine is to provide patients with the most individualized treatment possible. This requires a precise understanding of what is happening at the cellular level. For the first time, researchers at the Technical University of Munich (TUM) have now succeeded in mapping the interactions of 144 active substances with around 8,000 proteins. The results could help to identify previously unknown potential benefits of existing drugs. Practically all drugs either affect, produce or eliminate proteins – or are, in fact, proteins. But what exactly happens when a high or low dose is taken? And what is going ...

Companies and institutes are currently working on biotechnological processes for the production of dairy products without the use of cows: In so-called precision fermentation, egg and milk proteins are produced with the help of bacteria, yeasts or other fungi. This results in foods such as milk or cheese with a familiar flavour and texture. Supporters hope that this will lead to more sustainable food production, as nutrient-rich proteins can be produced using fewer resources. But will consumers accept such products? Researchers at the University of Göttingen have found that a large proportion of German consumers are willing to try and buy cheese produced in this way. ...
