The transport of mercury ions across intestinal epithelial cells can be studied for toxicology assessments by using animal models and static cell cultures. However, the concepts do not reliably replicate conditions of the human gut microenvironment to monitor in situ cell physiology. As a result, the mechanism of mercury transport in the human intestine is still unknown. Read Full Article Here

Nanomedicines took the spotlight during the COVID-19 pandemic. Researchers are using these very small and intricate materials to develop diagnostic tests and treatments. Nanomedicine is already used for various diseases, such as the COVID-19 vaccines and therapies for cardiovascular disease. The “nano” refers to the use of particles that are only a few hundred nanometers in size, which is significantly smaller than the width of a human hair. Read Full Article Here

Plastics are ubiquitous in our society, found in packaging and bottles as well as making up more than 18% of solid waste in landfills. Many of these plastics also make their way into the oceans, where they take up to hundreds of years to break down into pieces that can harm wildlife and the aquatic ecosystem. Read Full Article Here

The International Maritime Organization (IMO), the United Nations agency that governs safety and environmental standards for shipping worldwide, has adopted a U.S. proposal to increase protections for endangered blue, fin and humpback whales off the California coast. The proposal takes effect this summer and expands areas that vessels should avoid to give whales more space, and extends vessel traffic lanes west of, in and around NOAA’s Channel Islands National Marine Sanctuary.

A new plasma operation scenario Super I Mode was discovered and demonstrated on the Experiment Advanced Superconducting Tokamak (EAST). The new high-confinement and self-organizing mechanism represents the reliability and advancement of the machine itself but also offers insights into how to better maintain the plasma and its operating stability.

The optical, electrical and mechanical properties of some materials change depending on the direction or orientation of the material. Depending on how wood is cut, for example, the orientation of the wood grain can result in a stronger or weaker material with different appearances. This same principal applies to ultrathin, two-dimensional (2D) materials with unique properties such as magnetism. Read Full Article Here

Whisper networks—informal channels that women use to warn others about sexual harassment, abuse or assault—take root because formal reporting systems can re-traumatize people who have been harmed. That’s what I found while conducting research on this topic for my dissertation. Read Full Article Here

While promiscuity among humans is often scorned, symbiotic promiscuity can be a sign of excellent teamwork in other species. Plant growth, especially in legumes, flourishes through mutualistic interactions with soil bacteria, commonly known as rhizobia. A successful interaction culminates with the formation of a root nodule, where rhizobia provide nitrogen to the plant. This association depends on complex chemical dialogs, which restrict plant-bacterial compatibility. However, exceptional cases of symbiotic promiscuity may occur, and certain legumes can develop nitrogen-fixing nodules with diverse rhizobia.

Traditionally, active metasurface research has primarily focused on changing the dielectric constant and permeability of the substrate, which frequently results in resonance effect and ohmic loss. However, a reconfigurable metasurface based on mechanical deformation can avoid these problems. At the moment, though, mechanical reconfigurable metasurfaces represented by the MEMS and FIB-induced deformation processes are difficult to fabricate or have limited resilience. As a new type of liquid crystal polymer material, Liquid Crystal Elastomer (LCE) can realize controllable and recoverable elastic deformation in response to temperature rise or light irradiation, which has generated enormous interest in the communities of chemistry, materials, and bionics.

Human life is inextricably bound to light. Developments in science and technology have increased the popularity of artificial light and diversified the use of sunlight. However, inappropriate light radiation can be harmful to human health and well-being. As important channels for external light, windows play a vital role in the regulation of light in buildings, vehicles, and aircraft. Read Full Article Here

The perception and negotiation abilities of more charismatic CEOs result in higher IPO prices and smaller offer price ranges for their firms, according to new research published in the Strategic Entrepreneurship Journal. The study found that humility among CEOs, on the other hand—while celebrated in the media—actually goes against the implicit leadership theory, which suggests that people expect leaders to be strong, charismatic, and aggressive visionaries.

In a warming world, coal can often seem the “bad guy.” But we can do other things with coal besides burn it. A team at Ohio University used the Pittsburgh Supercomputing Center’s Bridges-2 system to carry out a series of simulations showing how coal might eventually be converted to valuable—and carbon-neutral—materials like graphite and carbon nanotubes.
