It follows previous studies that showed seaweed cut methane emissions 82% in feedlot cattle ...

The consumption of milk products, eggs and fish has a positive effect on childhood development in Africa. This has been demonstrated in a recent study by the CABI's regional centre for Africa in Nairobi, Kenya and the University of Bonn. The researchers used representative data from five African countries with over 32,000 child observations. If the children had a diet containing animal products, they suffered less from malnutrition and related developmental deficiencies. The study has now been published in the journal PNAS.  Almost 150 million children under the age of five around the world suffer from serious growth and developmental ...

Fukuoka and Tsukuba, Japan—Researchers have uncovered key insights about how liquid crystals, materials capable of forming complex ordered structures, transform between different phases. Published in PNAS, the study provides a clearer understanding of how these materials change their structures at the microscopic level. This research could provide a means to give a deeper insight into the transformation between different structures in a wider variety of materials.

A new collection of published papers offers the most detailed and comprehensive breakdown yet of how water injected into the Permian Basin during oil and gas operations is changing subsurface pressures and causing earthquakes. The Permian Basin in West Texas is the country’s most prolific energy-producing region, accounting for more than 40% of the nation’s oil production and about 15% of gas production. However, energy production has caused earthquakes and other challenges in recent years as oil and gas operators now manage roughly 15 million barrels of produced wastewater each day. This briny water comes to the surface ...

Where do you see patterns in chaos? It has been proven, in the incredibly tiny quantum realm, by an international team co-led by UC Santa Cruz physicist Jairo Velasco, Jr. In a new paper published on November 27 in Nature, the researchers detail an experiment that confirms a theory first put forth 40 years ago stating that electrons confined in quantum space would move along common paths rather than producing a chaotic jumble of trajectories. Electrons exhibit both particle and wave-like properties—they ...

Brazilian scientists have determined that ancient specimens of partially domesticated maize (Zea mays, also known as corn) originally from Peruaçu Valley in Minas Gerais state (Brazil) were the farthest from Mexico, the plant’s historic center of origin, of any finds made so far.

UNIVERSITY PARK, Pa. — The more time you spend on social media, the likelier you are to have come across a viral post that seems too strange to be true. Brief scientific literacy interventions, especially those that focus on critical thinking skills, may help to undermine conspiracy beliefs and behaviors before the conspiracy theories have a chance to take root, according to a team led by Penn State researchers. The team published their findings in the Journal of Consumer Research. \“While some conspiracy beliefs may seem relatively harmless, others — about vaccines, genetically modified organisms and climate change, for example ...

CHAMPAIGN, Ill. — Teenagers use generative artificial intelligence for many purposes, including emotional support and social interactions. A study by University of Illinois Urbana-Champaign researchers found that parents have little understanding of GAI, how their children use it and its potential risks, and that GAI platforms offer insufficient protection to ensure children’s safety. The research paper by information sciences professor Yang Wang, the co-director of the Social Computing Systems Lab, and doctoral student Yaman Yu is one of the first published sources of data on the uses and risks of GAI for children. Wang ...

University of Texas at Arlington senior Ken Perry has always been interested in how the heart works. This curiosity led the Arlington High School graduate to start working in the lab of UTA kinesiology Professor R. Matthew Brothers during his second year of college. Now, two years later, Perry is the recipient of two research awards from the American Physiological Society (APS) for his research on a connection between high-fat meals and cardiovascular health. “I always wanted to learn about heart and blood flow, so when friend of mine interested in research encouraged me to apply for the SURPINT program ...

ITHACA, N.Y. – Cornell University researchers have created the smallest walking robot yet. Its mission: to be tiny enough to interact with waves of visible light and still move independently, so that it can maneuver to specific locations – in a tissue sample, for instance – to take images and measure forces at the scale of some of the body’s smallest structures. The team’s paper, “Magnetically Programmed Diffractive Robotics,” published in Science. “A walking robot that’s small enough to interact with and shape light effectively takes a microscope’s lens and puts it directly ...

Salicylic acid is vital for protecting plants from pathogens, but its synthesis remains unclear. A recent study by Shinshu University researchers has discovered that the protein HSR201 is key to its production. They found that HSR201 localizes to specific organelles called peroxisomes through a unique targeting signal. This discovery improves our understanding of how plants produce salicylic acid and could pave the way for developing engineered crops with improved disease resistance. Plant hormones, or phytohormones, are vital for plant growth, adaptation, and defense. ...

A new study from The Hospital for Sick Children (SickKids) and Institut Curie reveals how stem cells sense and respond to their environment, with implications for inflammatory bowel disease and colorectal cancer.  Stem cells constantly adapt to their environment to maintain organ and tissue health, informed by chemical signals and physical forces. When they do not function as intended, stem cells can result in a number of health conditions including inflammatory bowel disease (IBD) and colorectal (bowel) cancer, where they continue to divide until a tumour forms. Until ...

La Jolla, Calif. (December 2, 2024) — A new study from scientists at the University of California San Diego introduces a powerful new approach to understanding the operation of crisis pregnancy centers, non-profit organizations dedicated to an anti-abortion agenda. The study published in JAMA Internal Medicine provides the first account of the practices of crisis pregnancy centers (CPC) operating in the United States.  "While our study shows crisis pregnancy centers provide valuable community services, like parenting classes,  there is a clear need for consumer safety measures to prevent the promotion and use of their ...

A team of astronomers has found that Venus has never been habitable, despite decades of speculation that our closest planetary neighbour was once much more like Earth than it is today. The researchers, from the University of Cambridge, studied the chemical composition of the Venusian atmosphere and inferred that its interior is too dry today for there ever to have been enough water for oceans to exist at its surface. Instead, the planet has likely been a scorching, inhospitable world for its entire history. The results, reported in the journal Nature Astronomy, have implications for understanding Earth’s uniqueness, and for the search for life on planets outside ...
