Researchers at North Carolina State University developed a nondestructive technique to collect cellular material from historical parchment manuscripts without damaging them. This allows for genetic analyses that provide new insights into past cultural and agricultural practices.
A new species of ladybird beetle, Parastethorus pinicola, was discovered on a pine tree at Kyushu University's Hakozaki Satellite. The beetle measures just over one millimeter in length and is the first major update to Japanese ladybird classification in 50 years.
Researchers at Kobe University developed a method to preserve iPS cells directly in their culture dishes using D-proline as a cryoprotectant. This allows for easy automation of the process, reducing costs and increasing efficiency in regenerative medicine and drug discovery research. The breakthrough enables the direct freezing, thawin...
The University of Leicester's Space Park Leicester is designing a Double-Walled Isolator (DWI) to safely store and analyze extra-terrestrial materials, including Martian samples. The project aims to provide a high-level of containment and cleanliness to avoid cross-contamination.
Researchers at Tufts University have developed a paper-based device that accurately measures HIV viral loads from dried blood samples, outperforming industry standards. The device, called the plasma spot card, was tested on 75 South African patients and showed improved accuracy in detecting drug-resistant mutations.
The OSIRIS-REx mission returned a large sample from asteroid Bennu, which Japanese collaborators detected includes all five nucleobases required for life. The analysis revealed high concentrations of ammonia and nitrogen-rich organic matter.
The American College of Chest Physicians has released a new clinical guideline on endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) specimen processing and handling to standardize the process. The guidelines aim to improve diagnostic yield and specimen preservation for downstream ancillary testing.
A handheld diagnostic lab developed by UCLA researchers can fully automate pooled testing and detect multiple diseases, reducing costs and usage of scarce supplies. The technology can be easily manufactured, deployed, and performed at a doctor's office or mass testing sites, helping authorities prepare for future pandemics.
A Rutgers University study has revealed that spice containers are a common source of cross-contamination in kitchens, with nearly half of samples showing evidence of contamination. The study's findings highlight the importance of proper handwashing and sanitizing of kitchen surfaces to prevent the spread of foodborne illnesses.
A new virus detection method has been developed by KAUST researchers using magnetic nanoparticles, allowing for fast, safe and cheap testing of viruses in clinical and wastewater samples. The method rivals commercial viral-RNA extraction kits while lowering the risk of handling potentially infectious samples.
A study found that soiled clinical linens can contaminate surfaces with C. difficile bacteria, even in clean areas of a laundry facility. This highlights the potential risk of environmental contamination and emphasizes the importance of infection prevention in healthcare settings.
