Living cells are highly organized, yet they are not assembled using rigid blueprints or by following a predetermined plan. Instead, order emerges on its own from countless interactions between molecules that are constantly moving and rearranging. One of the most striking examples of this emerging order is the left–right asymmetry. This type of chirality—the property of an object that makes it different from its mirror image—is essential for many biological processes and can be observed throughout nature. Interestingly, how both small- and large-scale order arise from interactions ...

While there are plenty of historical topics U.S. citizens agree on—generally events and figures from the Civil War up to the end of the Cold War—the birth of the nation isn’t one of them, according to a new report from Johns Hopkins SNF Agora Institute and a nonprofit called Millions of Conversations.  The country’s founding has become one of the most polarizing eras in history, the new research finds, just as the United States is starting to celebrate its 250th anniversary this year. Older generations in the survey believe American ...

CLEVELAND—Researchers at Case Western Reserve University have discovered a way to breach one of cancer’s most stubborn defenses: the impenetrable fortress that solid tumors build around themselves. By injecting nanobubbles filled with inert gas into tumors and “jiggling” them with ultrasound, the team successfully broke down tumor barriers enough for treatment-bearing molecules to get inside, according to results of a new study published in ACS Nano. “The physical barrier is limiting delivery of cancer drugs, especially for new immunotherapies,” ...

Plastics have become an integral part of modern society thanks to their durability and resistance to water. However, precisely these properties turn them into persistent disruptors of ecological cycles. As a result, unrecovered plastic is accumulating across ecosystems and becoming an increasingly ubiquitous component of global food chains, raising growing concerns about potential impacts on human health. In an effort to address this challenge, the use of biomaterials as substitutes for conventional plastics has long been explored. However, their widespread adoption has been limited by a fundamental drawback: most biological materials weaken when ...

Studying foraging behavior in marine mammals is especially difficult. Unlike terrestrial animals, which can often be directly observed, marine mammals feed underwater and across vast, remote areas, making it challenging to determine where and what they eat. Most diet studies rely on stomach contents of stranded animals, making it impossible to know where or when feeding occurred. In the Arctic, however, where Inuit communities hunt marine mammals as part of a subsistence lifestyle, this limitation can be overcome. By comparing ...

The days of dropping a thermal imaging camera and replacing an expensive lens are coming to an end with a new repairable lens developed by Flinders University scientists.  A high-performance lens for infrared cameras invented by Flinders researchers is emerging as a lower cost, more sustainable option for industries whish use thermal imaging cameras, including security and surveillance, medicine, electrical engineering, electronics, defence and autonomous vehicle operation.  The new infrared thermal imaging lens, ...

Antimicrobial resistance (AMR) in common foodborne bacteria such as Salmonella and Campylobacter continues to be a public health concern across Europe, according to a new joint report from the European Food Safety Authority (EFSA) and the European Centre for Disease Prevention and Control (ECDC). While resistance to commonly used antimicrobials remains widespread in foodborne bacteria such as Salmonella and Campylobacter, several countries have reported progress in reducing resistance levels in humans and in food-producing animals. Because these foodborne bacteria can spread from animals and food to humans, causing severe infections ...

CLEVELAND—Among the enduring challenges of storing energy—for wind or solar farms, or backup storage for the energy grid or data centers—is batteries that can hold large amounts of electricity for a long time. In addition to having a large capacity—potentially enough to power a neighborhood or small city for days or weeks—ideally these batteries would be safe, affordable and environmentally harmless. With an eye toward meeting those benchmarks, researchers at Case Western Reserve University are developing novel electrolytes—fluids that can conduct ions—for ...

Mobile robots must continuously estimate their position to navigate autonomously. However, satellite-based navigation systems are not always reliable: signals may degrade near buildings or become unavailable indoors. To operate safely and efficiently, robots must interpret their surroundings using onboard sensors and robust localization algorithms. Researchers at Miguel Hernández University of Elche (UMH) in Spain have developed a hierarchical localization system that significantly improves robot positioning in large, changing environments. The method addresses one of the most challenging ...

Interbrain synchrony is the simultaneous activity of neural networks across the brains of people who are socially interacting –- for example talking, learning, singing, or working together. Having brains that are thus synchronized or ‘in tune’ can help people boost their emotional connection, improve communication, and align their attention. Neural synchrony is thought to be important for healthy bonding between parents and children. And now, a team of scientists in the UK has found that neural synchrony ...

Hip fractures are common in the elderly, with many patients experiencing a decline in Activities of Daily Living (ADL) post-surgery. Therefore, postoperative rehabilitation plays a crucial role in helping patients recover to their pre-injury ADL level. Previous studies have shown that providing rehabilitation on weekdays and outside of normal business hours, such as on the weekend and public holidays, during hospitalization promotes improvements in ADL. However, many medical institutions ...

Researchers at Kumamoto University have discovered that behavioral changes during the COVID-19 pandemic—particularly widespread mask-wearing—may have reduced the risk of certain types of heart attacks triggered by air pollution. The study, led by Dr. Masanobu Ishii and colleagues, was published in the European Society of Cardiology’s flagship journal, European Heart Journal. Air pollution and heart attacks Fine particulate matter known as PM2.5—tiny airborne particles small enough to penetrate ...

Professor Pei-Qiang Huang's research group at Xiamen University recently reported the first reduction-cross-coupling reaction of aliphatic tertiary amides with 4-cyanopyridine via iridium and photoredox tandem catalysis. This method is based on the formation of imineonium through iridium-catalyzed hydrosilylation and acid catalysis, followed by tandem photocatalysis to generate two radicals (C,N,N trialkyl α-amino radical and stable 4-cyano-1,4-dihydropyridine radical) which then undergo ...

A new Edith Cowan University (ECU) study has found advertisements that encourage healthy choices can reduce cravings and intentions to consume unhealthy foods, and in some cases a 15-second message may be more effective than traditional 30-second commercials.  Led by Dr Ross Hollett, the research investigated how the length and framing of junk food and anti-junk food ads influence immediate cravings among adults in different Body Mass Index (BMI) categories.  Anti-junk food ads are public health campaigns designed to discourage people from eating unhealthy foods, either by warning about ...

A woman was buried with two children, but they were not her own. In another grave, two children were placed. They were not siblings and were more distantly related, perhaps cousins. In a new study, researchers at Uppsala University have clarified family relationships in four graves from a 5,500-year-old hunter-gatherer culture at Ajvide on Gotland. DNA analyses suggest that the people were well aware of family lineages and that relationships beyond the immediate family played an important role. Ajvide is one of the most important Stone Age sites in Scandinavia and is ...

The effectiveness of exercise therapy to ease the symptoms of osteoarthritis is likely minimal, short lived, and probably no better than no treatment at all, suggests an overarching (umbrella) systematic review and pooled data analysis of the available evidence, published in the open access journal RMD Open.   The findings question the universal promotion of exercise as a first line treatment to ease pain and improve physical function in all those living with the degenerative joint disease, and highlight the need to revisit research priorities, conclude the researchers.   Exercise ...

ANN ARBOR—The price of copper must at least double in order to spur the development of new copper mines to meet the world's growing demand for the metal, according to a team led by a University of Michigan researcher. A research team led by U-M geologist Adam Simon examined barriers to producing the copper necessary to meet demands for the metal under different scenarios. They found that meeting basic copper demand is possible, but will require higher prices and reforms to the permitting process to encourage ...

As aging populations and rising diabetes rates drive an increase in chronic wounds, more patients face the risk of amputations. UC Riverside researchers have developed an oxygen-delivering gel capable of healing injuries that might otherwise progress to limb loss. Injuries that fail to heal for more than a month are considered chronic wounds. They affect an estimated 12 million people annually worldwide, and around 4.5 million in the U.S. Of these, about one in five patients will ultimately require a life-altering amputation. The new gel, tested in animal models, targets what researchers believe is a root cause of many chronic wounds: a lack of oxygen ...

In the complex world of soil and water chemistry, certain minerals act like microscopic sponges, soaking up pollutants and keeping our environment safe. Among the most dangerous of these pollutants is hexavalent chromium, Cr(VI), a highly toxic and mobile substance often found at industrial and mining sites. Now, a groundbreaking study published in Carbon Research has identified the specific "superstar" minerals that are best at neutralizing this threat while simultaneously locking away organic carbon. The research, ...

Sandy soils are among the most challenging environments for agriculture because water drains quickly and nutrients are easily lost. A new long-term field experiment shows that combining biochar with compost and sludge can dramatically improve how sandy soils retain water, offering a practical strategy for farming in drought-prone regions. Researchers conducted a 441-day lysimeter study to examine how different organic amendments influence the water balance of sandy soil under realistic environmental conditions. The team compared single amendments and combinations of biochar, compost, and sludge, monitoring soil moisture, drainage, ...

Mangrove forests are widely known as powerful natural carbon sinks, but new research shows that a lesser-known form of carbon stored in their soils could significantly influence how coastal ecosystems store and transport carbon. A new study investigating mangrove soils in the Zhangjiang Estuary of China reveals that black carbon, a highly stable product of incomplete combustion from sources such as wildfires and fossil fuel burning, persists in mangrove sediments and may contribute to long-term carbon sequestration in coastal environments. The findings also highlight the importance of dissolved ...

A new study from Adelaide University is turning a spotlight on those tablet versions, finding that the absorption-enhancing ingredient salcaprozate sodium (SNAC) may have measurable adverse biological effects for the gut and beyond.   It is the first in vivo study to systematically evaluate the effects of repeated SNAC exposure on gut microbiota composition, function, and metabolic outcomes. In an animal model extending 21 days, researchers identified:   Lower levels of beneficial gut bacteria that help break down dietary fibre Reduced short-chain fatty acids which protect the gut lining and help regulate inflammation Higher levels of blood inflammatory ...
