The gross price of insulin in the U.S. is more than nine times higher than in 33 high-income comparison nations, according to a new RAND report.   Although the cost differences of insulin between the U.S. and other nations varied depending on the comparison country and the type of insulin, U.S. prices were always higher -- often five to 10 times higher -- than those in other countries. The new report updates findings from earlier RAND work about U.S. insulin prices.   After accounting for rebates and other discounts often offered by drug manufacturers, the price of a unit of insulin remained 2.3 times higher in the ...

For centuries, doctors have used their hands as essential diagnostic tools — exploring joints and palpating abdomens to assess a patient’s health. Often a cancer will reveal itself as a lump or unusual stiffness in a normally bouncy tissue or organ. More recently, the relationship between stiffness and cancer has been documented through biophysical studies and clinical trials, particularly in liver and breast cancer. For example, stiffness is a primary hallmark of liver cirrhosis, which can progress to liver cancer. Now researchers ...

Among the buzziest consumer technologies right now are “mixed reality” or “spatial computing” headsets that convincingly blend views of the real world with digital content. A key enabling technology behind these gizmos is passthrough video, which involves blocking out all light so users must rely on cameras on the headsets to see the external world around them via real-time video playing on tiny screens. The arrangement allows users to physically interact with their environments and go about daily activities but with added digital content displayed, ranging from familiar device apps to innovative gaming scenarios. ...

By Maegan Murray Scientists have spent decades finding ways to efficiently and affordably degrade plant materials so that they can be converted into useful bioproducts that benefit everyday life.  Bio-based fuels, detergents, nutritional supplements, and even plastics are the result of this work. And while scientists have found ways to degrade plants to the extent needed to produce a range of products, certain polymers such as lignin, which is a primary ingredient in the cell wall of plants, remain incredibly difficult to affordably break down without adding pollutants back into the environment. These polymers can be left behind as waste products with ...

Researchers at the Centre for Genomic Regulation (CRG) in Barcelona and the Spanish National Cancer Research Centre (CNIO) in Madrid have captured the world’s first high-resolution images of the earliest moments of microtubule formation inside human cells. The findings, published today in the journal Science, lay the foundations for potential breakthroughs in treating many different types of diseases ranging from cancer to neurodevelopmental disorders. “Microtubules are critical components of cells, but all the images we see in textbooks describing the first moments of their creation are models or cartoons based ...

We often think of fish as carefree swimmers in the ocean, reacting to the world around them without much forethought. However, new research from the Okinawa Institute of Science and Technology (OIST) suggests that our marine cousins may be more cognizant than we credit them for.  By observing how a colony of clown anemonefish (Amphiprion ocellaris) – the species of the titular character in Finding Nemo – reacts to intruders in their sea anemone home, OIST researchers have found that ...

Bacteria are traditionally imagined as single-cell organisms, spread out sparsely over surfaces or suspended in liquids, but in many environments the true bacterial mode of growth is in sticky clusters called biofilms. Biofilm formation can be useful to humans—it is integral, for example, to the production of kombucha tea. But it is more often problematic, because it makes it more difficult to control bacterial growth: When bacterial cells produce a biofilm, it acts as a shield against outside invaders, making the bacteria more ...

· Researchers at the Centre for Genomic Regulation (CRG) , the Spanish National Cancer Research Center (CNIO) and the IBMB-CSIC solve a key problem in biology: how human cells build their microtubules · During cell division, microtubules function as nanometer-thick long ‘ropes' inside cells that pull chromosomes apart so that each daughter cell receives a copy of the genetic material · The work published in Science lays the groundwork for future breakthroughs in the treatment of diseases ranging from cancer to neurodevelopmental disorders   Cells in the human body are constantly dividing. With each division the genetic information contained in the ...

Single-cell projectome analysis has revealed previously unknown spatial organization principles of the brain-wide structure and connectivity of more than 10,000 individual hippocampal neurons in the mouse brain, according to a new study. Specialized projections called axons allow neurons to transmit signals to other neurons across the brain. The hippocampus (HIP) – one of the most extensively studied brain regions – plays a crucial role in many crucial brain functions, including learning, memory, ...

The effect of large herbivores on plant abundance and diversity depends more on their size and diet than whether they are native or introduced into their host ecosystems, according to a meta-analysis of more than 200 studies worldwide. The findings counter the widely held notion that the impacts of introduced megafauna are distinct and more harmful than those of native megafauna and suggest that trait-based ecology provides better insight into megaherbivore-plant interactions than concepts of species origin. Large mammal herbivores play a key role in shaping ecosystems and biodiversity by consuming vegetation, dispersing seeds and nutrients, and creating ...

A computational analysis has highlighted the poorly understood relationships and elusive histories of modern sign languages worldwide, revealing two major sign language families shaped by geopolitical forces and relevant signing communities. The findings show that the computational methods applied – which have been useful in understanding spoken languages – can be extended to the study of sign languages; as such, they offer promise for addressing the disparities in our understanding of other marginalized and diverse ...

A new machine learning model – trained on video and audio recorded from the first-person perspective of one young child for over a year – has provided new insights into early language acquisition. Not only do the findings offer a valuable framework to understand how children learn words and concepts, but they could be critical in developing artificial intelligence (AI) systems that can learn language in more human-like ways. Beginning around 6 to 9 months of age, children begin acquiring their ...

New research published today in the journal Science has concluded that eradicating animals on the basis that they are not native in order to protect plant species, can be a flawed practice costing millions of dollars, and resulting in the slaughter of millions of healthy wild animals. Introduced large herbivores, or megafauna, are claimed to have distinct and harmful ecological impacts, including damaging sensitive plants and habitats, reducing native plant diversity, and facilitating introduced plants. However, up to now these impacts have been studied without comparison to a proper ...
