Boston, MA— A new study led by the Harvard Pilgrim Health Care Institute evaluates the impact of a voluntary code intended to improve ethical recruitment of physicians from World Health Organization-designated shortage countries. While the Code initially reduced physician migration from these countries, the research finds it did not improve their physician supply, highlighting the need for broader investments to strengthen global health systems. The study is published on February 6 in JAMA Health Forum. Global health care workforce shortages are intensified when physicians from lower-to-middle income countries (LMICs) migrate to high-income ...

“The concept of time has troubled philosophers and physicists for thousands of years, and the advent of quantum mechanics has not simplified the problem,” says Professor Hugo Dil, a physicist at EPFL. “The central problem is the general role of time in quantum mechanics, and especially the timescale associated with a quantum transition.” Quantum events, like tunnelling, or an electron changing its state by absorbing a photon, happen at mind‑bending speeds. Some take only a few tens of attoseconds (10-18 seconds), ...

Tungsten carbide–cobalt (WC–Co) is prized for its hardness, but that same property makes it unusually difficult to shape. The current process is wasteful and expensive for the yield produced, and an economically sensible method for creating these materials is long overdue. WC-Co cemented carbides are important in fields that require high wear resistance and hardness, such as cutting and construction tools. Currently, these carbides are made using powder metallurgy, utilizing high pressure and sintering machines to combine the WC and Co powders to yield a manufactured cemented carbide. Though this method does produce highly durable and hard final products, a lot of expensive ...

Fukuoka, Japan—Cancer is one of the leading causes of death worldwide, marked by the uncontrolled growth of abnormal cells. What makes it more dangerous is the ability of cancer cells to move quickly through the body, allowing them to invade surrounding tissues. While this behavior is well known, the mechanism behind this rapid spread remains unclear. Researchers from Kyushu University set out to fill this gap and unveiled a new physical process that helps cancer cells move rapidly throughout the body. This study was led by Professor Junichi Ikenouchi from Kyushu University’s Faculty of Medical Sciences, along with his colleagues at Kyushu University, in collaboration with ...

COLUMBUS, Ohio – A new study in mice hints at the potential to use tiny particles made with RNA molecules to deliver chemotherapy drugs and other therapies directly to tumors, killing cancer cells without generating an immune response or toxicity-related side effects. Researchers constructed tiny molecular clusters called RNA micelles, loaded them with potent chemo drugs and an RNA molecule that blocks cancer survival, and placed a tumor targeting molecule on their outer wall that attaches to receptors on cancer cell surfaces to enhance delivery. Treatment with these RNA micelles almost ...

Earth’s surface is covered by more than a dozen tectonic plates, and in subduction zones around the world—including the Japanese Islands—plates converge and dense oceanic plates sink into the Earth’s interior. These regions, especially plate boundaries, are known for frequent seismic activity. In recent years, scientists have increasingly emphasized that water plays a crucial role in earthquake phenomena in subduction zones, and thus conducted active research to investigate the influence of water on various processes occurring within earthquake source regions. When water is supplied, peridotite—the primary constituent of ...

Early in the 1969 film “Midnight Cowboy,” Dustin Hoffman, playing the character of Ratso Rizzo, crosses a Manhattan street and angrily bangs on the hood of an encroaching taxi. Hoffman’s line — “I’m walking here!” — has since been repeated by thousands of New Yorkers. Where cars and people mix, tensions rise.  And yet, governments and planners across the U.S. haven’t thoroughly tracked where it is that cars and people mix. Officials have long measured vehicle traffic closely while largely ignoring pedestrian traffic. Now, an MIT research group has assembled a routable dataset of sidewalks, ...
