A new RAND Corporation report finds that the basic infrastructure to support elementary (grades K-5) social studies instruction – academic standards, accountability requirements, assessment programs – is inadequate in many states. Even where state-level infrastructure to guide teachers’ instruction is in place, its comprehensiveness and quality vary greatly. Support and guidance at the district and school level to underpin social studies instruction are also lacking compared to other core academic ...

Scientists at Lawrence Berkeley National Laboratory (Berkeley Lab) have developed a conductive polymer coating – called HOS-PFM – that could enable longer lasting, more powerful lithium-ion batteries for electric vehicles.  “The advance opens up a new approach to developing EV batteries that are more affordable and easy to manufacture,“ said Gao Liu, a senior scientist in Berkeley Lab’s Energy Technologies Area. The HOS-PFM coating conducts both electrons and ions at the same time. This ensures battery stability and high charge/discharge rates while enhancing battery life. The coating ...

BIRMINGHAM, Ala. – A United States Food and Drug Administration mandate to limit the dosage of acetaminophen in pills that combine acetaminophen and opioid medications is significantly associated with subsequent reductions in serious liver injury, researchers report in the medical journal JAMA. The federal mandate was announced in 2011 and implemented in 2014. “The FDA mandate that limits acetaminophen dosage to 325 milligrams per tablet in combination acetaminophen-opioid medications was associated with a significant and persistent decline in the yearly rate of hospitalizations and proportion per year of acute liver failure ...

WASHINGTON, March 7, 2023 – Proxy data – indirect records of the Earth’s climate found in unlikely places like coral, pollen, trees, and sediments – show interesting oscillations approximately every 100,000 years starting about 1 million years ago. Strong changes in global ice volume, sea level, carbon dioxide concentration, and surface temperature indicate cycles of a long, slow transition to a glacial period and an abrupt switch to a warm and short interglacial period. Milutin Milankovitch hypothesized that the timing of these cycles was controlled by the orbital parameters of the Earth, including the shape of its path around ...

A hormone called fibroblast growth factor 21 (FGF21) protects mice against ethanol-induced loss of balance and righting reflex, according to a study publishing on March 7 in the journal Cell Metabolism. “We’ve discovered that the liver is not only involved in metabolizing alcohol but that it also sends a hormonal signal to the brain to protect against the harmful effects of intoxication, including both loss of consciousness and coordination,” says co-senior study author Steven Kliewer of the University of Texas Southwestern Medical Center. “We’ve further shown that by increasing FGF21 concentrations even higher by injection, we can dramatically ...

At a glance: New research suggests female mice show more stable exploratory behavior than male mice, despite hormone cycles The results challenge a long-held assumption that hormones have a broad effect on behavior in female mice, making them less suitable for research The findings make a strong scientific case for increasing the inclusion of female mice in neuroscience and other experiments Mice have long been a central part of neuroscience research, providing a flexible model that scientists ...

About The Study: The findings of this study suggest that despite initial telemedicine gains at rural Veterans Affairs (VA) health care sites, the pandemic was associated with an increase in the rural-urban telemedicine divide across the VA health care system. To ensure equitable access to care, the VA health care system’s coordinated telemedicine response may benefit from addressing rural disparities in structural capacity (e.g., internet bandwidth) and from tailoring technology to encourage adoption among rural users.  Authors: Lucinda B. Leung, M.D., Ph.D., M.P.H., of the Veterans Affairs Greater Los Angeles Healthcare System in Los Angeles, is the corresponding ...

A United States Food and Drug Administration mandate to limit the dosage of acetaminophen in pills that combine acetaminophen and opioid medications is significantly associated with subsequent reductions in serious liver injury, according to a study led by investigators at the University of Alabama and Weill Cornell Medicine. The federal mandate was announced in 2011 and implemented in 2014. The results were reported March 7 in the medical journal JAMA. “After researchers found that more than 40 percent of acetaminophen-induced acute liver failure cases involved combination acetaminophen and opioid medications, and an FDA advisory ...

The selective breeding of grain crops is one of the main reasons why domesticated plants produce such excellent yields. Selecting the best candidates for breeding is, however, a remarkably complex task. On one hand, it requires a skilled breeder with trained eyes to assess plant resistance to disease and pests, crop growth, and other factors. On the other hand, it also requires precise tool-assisted measurements such as grain size, mass, and quality. Although all these standard measures are useful, none of them takes into account the number ...

Safe live microorganisms are found in a variety of foods we eat every day, from yogurt and other fermented foods, to raw fruits and vegetables. Despite the widespread idea that these mixtures of live microbes contribute to health, convincing evidence linking live dietary microbes to health benefits has been lacking. A new study provides some of the first real-world evidence that higher consumption of live microbes may promote health. A group of scientists led by the International Scientific Association for Probiotics and Prebiotics (ISAPP) classified over 9,000 individual ...

Sustainable energy solutions cannot be pulled out of thin air. However, combining air with metal and other frameworks may pave the way for environmentally friendly energy conversion and storage, according to a research team based in China.   They published their review of novel porous materials — called metal-organic frameworks (MOFs) and covalent organic frameworks (COFs) — and their potential to advance metal-air batteries on 03 March in Nano Research Energy.   The porous crystal material frameworks comprise various arrangements of bonded materials that can induce desired properties, including the ability to accelerate reactions between oxygen and metals ...

Macrophages are highly specialized cells of the immune system that help the body detect and fight deadly pathogens. In particular, M1-like macrophages detect and destroy tumor cells, and release protective chemokines such as interleukin (IL)-6 and tumor-necrosis factor α (TNF α), thus shielding the body from life-threatening pathologies like cancer. However, not all macrophages show anti-tumor potential. Certain types of macrophages, i.e., M2-like macrophages, promote tumor growth. Luckily, the desired macrophage phenotype—a set of traits resulting from the genetic makeup of the macrophage—can be activated by modulating the ...

OAK BROOK, Ill. – An artificial intelligence (AI) tool can accurately identify normal and abnormal chest X-rays in a clinical setting, according to a study published in Radiology, a journal of the Radiological Society of North America (RSNA). Chest X-rays are used to diagnose a wide variety of conditions to do with the heart and lungs. An abnormal chest X-ray can be an indication of a range of conditions, including cancer and chronic lung diseases. An AI tool that can accurately differentiate between normal and abnormal chest X-rays would greatly alleviate the heavy workload experienced by radiologists globally. “There is an exponentially growing demand for medical ...

A study at Hospital for Special Surgery (HSS) found that intraoperative three-dimensional (3D) imaging was superior to two-dimensional radiographs in confirming the accuracy of pedicle screw placement during spine surgery. The research was presented today at the American Academy of Orthopaedic Surgeons (AAOS) Annual Meeting in Las Vegas.   Many spinal surgeries require the use of implants called pedicle screws to stabilize the spine. Precise positioning of these screws is critical for a successful outcome. “Two-dimensional biplanar radiographs [BPR] ...

Researchers realized the multimodal locomotion control of the soft microrobot in magnetic fields and the grasping and transportation of micro-objects by the soft microrobot.   The new paper, published in Cyborg and Bionic System, details the process ...

Starting with the emergence of quantum mechanics, the world of physics has been divided between classical and quantum physics. Classical physics deals with the motions of objects we typically see every day in the macroscopic world, while quantum physics explains the exotic behaviors of elementary particles in the microscopic world. Many solids or liquids are composed of particles interacting with one another at close distances, which sometimes results in the rise of “quasiparticles.” Quasiparticles are long-lived excitations that behave effectively as weakly interacting particles. The idea of quasiparticles was introduced by the Soviet physicist Lev Landau in 1941, and ...

Network-assisted full-duplex (NAFD) systems enable uplink and downlink communications within the same time-frequency resources, so as to avoid the overhead of switching uplink/downlink modes. However, as the number of users and access points (APs) proliferated, mass access brings significant overhead in mode selection. In addition, the differentiated service demands among users also makes the effective utilization of resources difficult. Combined with network slicing technology, a slicing capacity-centered mode selection and resource optimization scheme is proposed. This scheme adopts a double-layer deep reinforcement ...

“As a Black woman, I’m invisible. They just erase your humanity. You don’t exist in front of them.” (Tessa, 33-year-old Black research assistant) “It wasn’t about disliking what I did or being judgmental of what I did. It was a different kind of problem, to not be acknowledged. They didn’t care. There was no curiosity. They didn’t give a f***. We were invisible.” (Brinda, 30-year-old South Asian consultant) Invisibility is a salient and recurring experience of mistreatment for women of colour working in traditionally white and male professions, two ...

Color plays a huge role in our lives — the hues we wear and decorate with are a way for us to signal who we are, where we’re from, and what we care about. And it’s been that way for a long time. In a new study in the Journal of Archaeological Science: Reports, archaeologists compared the colors on pieces of ancient Peruvian pottery. They found that potters across the Wari empire all used the same rich black pigment to make ceramics used in rituals: a sign of the empire’s influence. The Wari empire spread over Peru’s highlands and coastal areas from 600-1050 ...
