Poorly coiled frog guts help scientists unravel prevalent human birth anomaly
2024-02-19
How does our intestine, which can be at least 15 feet long, fit properly inside our bodies? As our digestive system grows, the gut tube goes through a series of dramatic looping and rotation to package the lengthening intestine. Failure of the gut to rotate properly during development results in a prevalent, but poorly understood, birth anomaly called intestinal malrotation. Now, in a study published in the journal Development, scientists from North Carolina State University have uncovered a potential cause of this life-threatening condition.
Intestinal malrotation affects 1 in 500 births but the underlying causes are not well understood. ...
Unveiling uremic toxins linked to itching in hemodialysis patients
2024-02-19
Niigata, Japan – Dr. Yamamoto et al. found the several uremic toxins as one of causes of itching in hemodialysis patients. Hemodialysis patients commonly experience itching on a daily basis, which is distributed throughout their bodies. They developed a "PBUT score" based on highly protein-bound uremic toxins (PBUT) that increase in the body with end-stage kidney disease. The PBUT score was associated with itching in hemodialysis patients.
I. Background of the Study
Patients with advanced chronic kidney disease (CKD) require kidney replacement therapy, such as hemodialysis, to manage their condition. Hemodialysis patients often experience various symptoms, ...

This tiny, tamper-proof ID tag can authenticate almost anything
2024-02-18
A few years ago, MIT researchers invented a cryptographic ID tag that is several times smaller and significantly cheaper than the traditional radio frequency tags (RFIDs) that are often affixed to products to verify their authenticity.
This tiny tag, which offers improved security over RFIDs, utilizes terahertz waves, which are smaller and travel much faster than radio waves. But this terahertz tag shared a major security vulnerability with traditional RFIDs: A counterfeiter could peel the tag off a genuine item and reattach it to a fake, and the authentication system would be none the wiser.
The researchers have now surmounted ...
Viruses that can help ‘dial up’ carbon capture in the sea
2024-02-17
DENVER – Armed with a catalog of hundreds of thousands of DNA and RNA virus species in the world’s oceans, scientists are now zeroing in on the viruses most likely to combat climate change by helping trap carbon dioxide in seawater or, using similar techniques, different viruses that may prevent methane’s escape from thawing Arctic soil.
By combining genomic sequencing data with artificial intelligence analysis, researchers have identified ocean-based viruses and assessed their genomes to find that they “steal” genes from other microbes or cells that process carbon in the sea. Mapping microbial ...

Scientists try out stone age tools to understand how they were used
2024-02-17
Tokyo, Japan – Researchers from Tokyo Metropolitan University crafted replica stone age tools and used them for a range of tasks to see how different activities create traces on the edge. They found that a combination of macroscopic and microscopic traces can tell us how stone edges were used. Their criteria help separate tools used for wood-felling from other activities. Dated stone edges may be used to identify when timber use began for early humans.
For prehistoric humans, improvements in woodworking technology were revolutionary. While Paleolithic (early stone age) artifacts point to the use of wood for simple tools such as spears ...

Anoxic marine basins are among the best candidates for deep-sea carbon sequestration
2024-02-16
(Santa Barbara, Calif.) — Anoxic marine basins may be among the most viable places to conduct large-scale carbon sequestration in the deep ocean, while minimizing negative impacts to marine life. So say UC Santa Barbara researchers in a paper published in the journal AGU Advances. As we explore ways to actively draw down the levels of carbon in the atmosphere, sending plant biomass to these barren, oxygen-free zones on the seafloor becomes an option worth considering.
“The big picture here is that all the best models that we have say that we have to do some form of net negative CO2 removal in order to hit climate goals,” said geochemist, geobiologist ...
