When lymphatic vessels fail, typically their ability to pump out the fluid is compromised. Georgia Institute of Technology researchers have developed a new treatment using nanoparticles that can repair lymphatic vessel pumping. Traditionally, researchers in the field have tried to regrow lymphatic vessels, but repairing the pumping action is a unique approach.
A lecturer and his research team from Faculty of Veterinary Science, Chulalongkorn University, have developed “FLAVO INNOVAC” nanovaccine for the prevention of bacterial gills diseases in freshwater fish species such as Tilapia and freshwater Asian sea bass. This nanovaccine is an effective solution that reduces the risk of death from diseases and the limitations of vaccine injections.
Some analysts say that the end of Moore’s Law is near, but Patrick Naulleau, the director of Berkeley Lab’s Center for X-Ray Optics (CXRO), says that it could be decades before the modern chip runs out of room for improvement, thanks to advances in materials and instrumentation enabled by the CXRO.
Placenta accreta spectrum (PAS) disorder occurs when the placenta remains attached to the uterus after childbirth. Now researchers have developed a blood test to identify this condition, enabling early intervention by high-risk pregnancy specialists.
Cornell researchers have identified a new way to measure DNA torsional stiffness – how much resistance the helix offers when twisted – information that can potentially shed light on how cells work.

Scientists have learned how to place crystalline defects in new materials with atomic-scale precision. This enables materials that can control excitons—energy carriers similar to subatomic particles. New research reveals how to create local energy wells that “capture” the excitons. This small but important step could lead to smaller, more efficient components for optical telecommunications.
Dmitri Simberg, PhD, associate professor in the University of Colorado Skaggs School of Pharmacy, released a new study of the effectiveness of different types of fluorescent labels used to monitor the accumulation of liposomes in tumors. The study was published on July 1, 2021, in ACS Nano.
RNA-based drugs may change the standard of care for many diseases, making personalized medicine a reality. So far these cost-effective, easy-to-manufacture drugs haven’t been very useful in treating brain tumors and other brain disease. But a team of researchers at Georgia Tech and Emory University has shown that a combination of ultrasound and RNA-loaded nanoparticles can temporarily open the protective blood-brain barrier, allowing the delivery of potent medicine to brain tumors.
Science Snapshots from Berkeley Lab: X-rays accelerate battery R&D; infrared microscopy goes off grid; substrates support 2D tech
Researchers reporting in ACS’ Nano Letters have made a prototype of an anode-free, zinc-based battery that uses low-cost, naturally abundant materials.
One of the proteins on the virus – located on the characteristic COVID spike – has a component called the receptor-binding domain, or RBD, which is its “Achilles heel.” That is, he said, antibodies against this part of the virus have the potential to the neutralize the virus.
A team of scientists led by Berkeley Lab has gained important new insight into electrons’ role in the harvesting of light in artificial photosynthesis systems.
Mixtures of nanoparticles show promise for solar fuels production. For example, gold donor particles absorb sunlight well, but they need an acceptor material to efficiently make fuel. Now, scientists have found a way to count electrons as they transfer between the two materials during these chemical reactions.
Scientists developed a new method of selectively attaching DNA strands to specific regions of nanoparticles. The DNA strands then dictate how the nanoparticles assemble into more complex architectures. The team used this approach to demonstrate 24 different nanoarchitectures.
Scientists are working on ways to build atomic structures to specifications and are studying these methods on a larger scale using ‘big atoms.’ These ‘big atoms’ are micro-particles of silica mixed into liquid crystals. Silica particles, when mixed into liquid crystals, can act a lot like individual atoms. The geometry of the particles determines how they interact with each other the same way the electrons around an atom determine how it interacts with other atoms. Scientists can observe interactions in these ‘big atoms’ with optical microscopes, removing the need for atomic-scale imaging.
Scientists at Berkeley Lab’s Molecular Foundry have designed a biocompatible polymer that has the potential to advance photothermal therapy, a technique that deploys near-infrared light to combat antibacterial-resistant infections and cancer.
Research by Nebraska engineers Peter and Eli Sutter points to a way to overcome the challenges of building multi-layered nanostructures
