Malnutrition links kidney disease, weaker muscles
Scientists at Osaka Metropolitan University utilized a Japan-developed, objective, and simple nutritional indicator called the Nutrition Risk Index (NRI) to unveil a long-suspected yet unverified relationship between sarcopenia and malnutrition in end-stage kidney disease patients. Their findings confirmed that malnutrition contributes to sarcopenia, which can be detected through NRI. End-stage kidney disease patients undergoing maintenance […]
Long-hypothesized ‘next generation wonder material’ created: Scientists have successfully synthesized graphyne, which has been theorized for decades
For over a decade, scientists have attempted to synthesize a new form of carbon called graphyne with limited success. That endeavor is now at an end, though, thanks to new research from the University of Colorado Boulder. Graphyne has long been of interest to scientists because of its similarities to the “wonder material” graphene — […]
New theory promises to reshape how we think about polymer superstructures: Predict how double-gyroid networks form
Polymer scientists at the University of Massachusetts Amherst recently announced in the journal Nature Communications that they have solved a longstanding mystery surrounding a nanoscale structure, formed by collections of molecules, called a double-gyroid. This shape is one of the most desirable for materials scientists, and has a wide range of applications; but, until now, […]
Scientists provide more than 50K camera trap images for massive study on Amazon wildlife
WCS scientists working in the vast Amazon Basin have contributed more than 57,000 camera trap images for a new study published in the journal Ecology by an international team of 120 research institutions. The study consists of 120,000-plus images taken in eight countries, representing the largest photo database to date of the Amazon’s staggering array […]
Higher wheat yields and protein content on the horizon
A team of international researchers has discovered a way to produce higher quality wheat. The scientists from the University of Adelaide and the UK’s John Innes Centre have identified a genetic driver that improves yield traits in wheat, which unexpectedly can also lead to increasing protein content by up to 25 per cent. “Little is […]
Scientists study links between obesity, age and body chemistry
A team of Clemson University scientists is making inroads in understanding the relationship between certain enzymes that are normally produced in the body and their role in regulating obesity and controlling liver diseases. According to Centers for Disease Control and Prevention (CDC) data collected in 2017-18, more than 42% of U.S. adults and 19% of […]
Emissions tied to the international trade of agricultural goods are rising
Earth system scientists at the University of California, Irvine and other institutions have drawn the clearest line yet connecting consumers of agricultural produce in wealthier countries in Asia, Europe and North America with a growth in greenhouse gas emissions in less-developed nations, mostly in the Southern Hemisphere. In a paper published today in Science, the […]
Self-propelled, endlessly programmable artificial cilia: Simple microstructures that bend, twist and perform stroke-like motions could be used for soft robotics, medical devices and more
For years, scientists have been attempting to engineer tiny, artificial cilia for miniature robotic systems that can perform complex motions, including bending, twisting, and reversing. Building these smaller-than-a-human-hair microstructures typically requires multi-step fabrication processes and varying stimuli to create the complex movements, limiting their wide-scale applications. Now, researchers from the Harvard John A. Paulson School […]
Mental illness plays havoc with the mind as well as the heart
University of South Australia scientists have uncovered another reason why society should be paying more attention to mental health: it is closely aligned to blood pressure and heart rate variations. A new study published in BioMedical Engineering draws a link between mental illness and widely fluctuating blood pressure, which can lead to cardiovascular disease and […]
New technique shows in detail where drug molecules hit their targets in the body
Scientists at Scripps Research have invented a way to image, across different tissues and with higher precision than ever before, where drugs bind to their targets in the body. The new method could become a routine tool in drug development. Described in a paper in Cell on April 27, 2022, the new method, called CATCH, […]
